Do the lines x+ 3y +7 =0, 3x+2y +11=0 and 2x+y+4=0 have a common point of interception?

To determine if the 3 lines have a common point, we'll
have to determine the solution of the system formed by the equations of the 3
lines:


x+ 3y +7 =0


We'll
subtract 7 both sides:


x + 3y = -7
(1)


3x+2y +11=0


We'll
subtract 11 both sides:


3x + 2y = -11
(2)


2x+y+4=0


We'll subtract 4
both sides:


2x + y = -4
(3)


We'll determine the matrix of the system. The
determinant is formed from the coefficients of x and
y.


           1    3


    A
=  3    2


           
2    1


We'll take the first2 lines and columns of the
matrix and we'll calculate the minor of the matrix
A.


         1    3


d
=   


         3     2 


d = 1*2
- 3*3 = 2 - 9 = -7


Now, we'll calculate the determinant
that we'll tell us if the system has solution or not.


This
determinant will be formed from the minor, the last row and the column of the terms from
the right side of equal:


        1    3   
-7


C =  3     2   -11


       
2    1    -4


C = -2*4 - 7*3 - 3*2*11 + 2*2*7 + 11 +
3*3*4


C = - 8 - 21 - 66 + 28 + 11 +
36


C = 20  - 1 - 30


C =
-11


Since C is not zero, the system has no
solutions.


If the system doesn't have
solutions, that means that the lines do not intercepting or do not have any common
point.

Show that (2x-1)^2-(x-3)^2 can be simplified to (3x-4)(x+2)?

We'll expand the squares using the
formula:


(a+b)^2 = a^2 + 2ab +
b^2


(a-b)^2 = a^2 - 2ab +
b^2


(2x-1)^2 = (2x)^2 - 2*(2x)*1 +
1^2


(2x-1)^2 = 4x^2 - 4x + 1
(1)


(x-3)^2 = x^2 - 2*x*3 +
3^2


(x-3)^2 = x^2 - 6x + 9
(2)


We'll subtract (2) from
(1):


4x^2 - 4x + 1 -  x^2 + 6x -
9


We'll combine like
terms:


3x^2 + 2x - 8


We'll
determine the roots of the quadratic:


3x^2 + 2x - 8 =
0


x1 = [-2+sqrt(4+96)]/6


x1 =
(-2+10)/6


x1 = 8/6


x1 =
4/3


x2 = (-2-10)/6


x2 =
-2


The quadratic could be written as a product of linear
factors:


3x^2 + 2x - 8 = 3(x - 4/3)(x +
2)


We'll multiply by 3 the first
factor:


3(x - 4/3)(x + 2) = (3x - 4*3/3)(x +
2)


3x^2 + 2x - 8 =
(3x-4)(x+2)


(2x-1)^2 - (x-3)^2 = (3x-4)(x+2)
q.e.d.

Please help me interpret the poem "The Line Gang" by Robert Frost.I'm having a really hard time trying to figure out what Robert Frost is trying...

In "The Line Gang" Robert Frost describes a team of men
who are setting telephone and telegraph wires.


They begin
by cutting down a forest, "replanting" the logs as telephone poles, and then stringing
wires between the poles:


They throw a forest down
less cut than broken.
They plant dead trees for living, and the
dead
They string together with a living
thread.

The wires will carry words, either spoken
on a telephone or "beaten out" on a telegraph; as the words travel along the wire,
however, they will be "as hushed as when they were a thought."  The men, though, do not
work quietly: "they go past /
With shouts
afar."


Frost was born in 1874 and died in 1963; he
witnessed the rapid transformation of America from a mostly rural country to a mostly
urban superpower.  In his personal life, he experienced urban life in his hometown of
San Francisco and rural life in his adopted home of New
England.


In "The Line Gang," Frost seems to be considering
the progress of industrialization and urbanization.  His attitude toward this process is
not simplistically "for" or "against."  He observes that the forest has been left
"broken" by the chopping down of trees, but he also seems to admire the power and
potential of the telephone and telegraph that can "set the wild at
naught."


Critics have observed that Frost often expresses a
"double" vision in his poems.  This can be seem in "The Line
Gang."

How does Ophelia's madness compare with that of Hamlet in Act 4?This question relates to Act 4 of Hamlet. Help!!!

The most important difference between Ophelia and Hamlet's
madness in Act 4 is the fact that Ophelia is, in fact, gone crazy, while Hamlet is
merely continuing to put his "antic disposition on."  Hamlet's behavior in the first few
scenes is "crazy" because he needs to maintain the illusion of madness as a cover story
for his murder of Polonius.  He didn't intend to kill him, but he did nevertheless kill
a man and that act has put in more danger with Claudius.  Claudius will now be seen as
more "justified" in taking action to control Hamlet.  Hamlet seems to enjoy acting crazy
because each time he does, he gets to say all the things he wants to say without regard
to the relationships he supposedly has with the people around.  He can tell Rosencrantz
and Guildenstern that they are merely sponges who soak up the King's favors.  He can
call his uncle his mother and defend himself.  He can insult the king by explaining how
the king, as worm food, could actually go through the digestive track of a lowly
beggar.  In his "right mind" he would never speak this
way!


Ophelia, on the other hand, has been put through too
much for her mind to handle, and she has truly lost her sanity.  Over the course of a
few days she has been told to break up with her boyfriend, who later told her to go to a
nunnery and that the never loved her.  That same boyfriend killed her father.  Her
behavior -- specifically the singing of seemingly random snatches of songs (alluding to
her father's death and her betrayal by Hamlet) and handing out flowers while hardly
engaging with those around her are sure signs of madness.  Her subsequent suicide is the
final act of a crazy woman. 

How did economic development during the Gilded Age affect urban residential patterns?

The main way in which economic development affected urban
residential patterns was by contributing to the beginnings of what we would now call
"sprawl."  Economic development (along with technological developments) created a large
new middle class that could move out of the inner cities and into new
suburbs.


As the Gilded Age brought in more large companies
and more of a need for white collar employees, the size of the middle class increased. 
At the same time, innovations in mass transit such as the development of electric
trolleys allowed the middle class to move away from the inner cities and out into the
"streetcar suburbs."

What is the effect of the speaker not completing the final line with a simile and why is this a useful strategy in "Harlem"?

In the eight lines enclosed within the frame (that is,
between the first andnext-to-last lines) we get four possibilities: The Dream may “dry
up,” “fester,”“crust and sugar over,” or “sag.” Each of these is set forth with a
simile,for example, “dry up / like a raisin in the sun.” By the way, the third ofthese,
“crust up and sugar over—like a syrupy sweet,” probably describes adream that has turned
into smiling Uncle Tomism. Similes can be effective, andthese are effective, but in the
final line Hughes states the last possibility (“Ordoes it explode?”) directly and
briefly, without an amplification. The effect is,more or less, to suggest that the fancy
(or pretty) talk stops. The explosion istoo serious to be treated in a literary way.
But, of course, the word “explode,”applied to a dream, is itself figurative.
That is, the last line is as “literary” or“poetical” as the earlier lines, but
it is a slightly different sort of poetry.

HELP!!! OK..am just asking this because its very shocking. In Act 2,after macbeth killed the king, lennox says its the guards.after confirming it...

There would be nothing wrong with Lennox seeing Macbeth
killing Duncan's two guards. Macbeth wants to silence them, but he pretends he is
carried away by righteous anger and is executing them on the spot for killing the King.
Macbeth is a high-ranking thane and can do such a thing without being in any legal
jeopardy. The two grooms are nobodies. The only reason Macduff questions Macbeth's
action is that it would have been much better to keep these two unfortunate men alive in
order to question them about the assassination of the man they were supposed to be
guarding. It seems obvious that if they were actually guilty of murdering King Duncan,
which they of course deny, then somebody must have bribed them to do it. Naturally
everybody--except Macbeth--would want to know who was the brains behind the
plot.


Lennox is presented as a young, naive lad. He was an
eye-witness to Macbeth's execution of the two terrified guards, but Lennox assumes that
they were guilty and that Macbeth acted justifiably in the heat of anger. When Malcolm
asks who killed his father, Lennox explains his
opinion:


readability="11">

Those of his chamber, as it seem'd, had
done't:
Their hands and faces were all badged with blood;
So were
their daggers, which unwiped we found
Upon their pillows:
They
stared, and were distracted; no man's life
Was to be trusted with them.      
   (2.3)



When Malcolm and
Donalbain decide to flee for their lives, it is easy for Macbeth to blame them for
hiring the two grooms to kill their father. But in Act 3, Scene 6, some time has passed,
and Lennox has become much older and wiser. He puts a much different spin on what
happened when he and Macbeth entered the dead king's
chamber.



Men
must not walk too late.
Who cannot want the thought, how
monstrous
It was for Malcolm and for Donalbain
To kill their
gracious father? Damned fact!
How it did grieve Macbeth! Did he
not straight,
In pious rage, the two delinquents tear,
That were the
slaves of drink and thralls of sleep?
Was not that nobly done? Ay, and wisely
too,
For ’twould have anger'd any heart alive
To hear the men
deny't.



Lennox is no longer
gullible. He has learned to see through appearances and to talk in innuendo. He realizes
the truth. Macbeth killed Duncan and then killed the two guards to keep them from giving
any evidence. From what Macbeth says to his wife after returning from killing the King,
it is possible that one of the guards might actually have seen Macbeth in the King's
chamber.


readability="9">

There's one did laugh in's sleep, and one
cried,
“Murder!”
That they did wake each other: I stood and heard
them:
But they did say their prayers and address'd them
Again to
sleep.                    
(2.2)



In any case, Macbeth
thought it prudent to kill them both. They were dead men anyway from the time Macbeth
and his wife hatched the plot to murder Duncan. The grooms were to be smeared with blood
and found that way when Duncan's body was discovered. Naturally it would be assumed that
they were paid by someone, but they would deny their guilt and would not be able to name
anyone who might have bribed them. Macbeth has an opportunity to kill them immediately
and seizes it.

How do companies maintain strong customer relationships in a marketing aspect?

Companies maintain strong customer relationships by
developing customer retention programs. The programs focus on keeping the customer,
maintaining the customer, improving the customer, and utilizing the customer. These can
come in all sorts of variations such as:


1) By selling a
product or service, follow-up with how the customer views that product or
service.


2) Provide any additional, new, or improvised
ancillary support items to the customer.


3) Allow the
customer to make suggestions and offer advice for new products and
services.


4) Use the customer to refer other customers and
reward that customer with discounts, cash, or other
products.


5) Promote that customer as a highly valued
customer in media documents and use quotes to acknowledge
customer.


6) Routinely provide customer with psychological
support such as happy birthday wishes, free calendars and other items that remind
the customer that he is highly valued.

"You never really understand a person until you consider things from his point of view - until you climb into his skin and walk around in it."How...

The Cunninghams fall into the 2nd of the 4 tiers of
Maycomb society:


  1. White Professionals (Atticus,
    Miss Maudie)

  2. Poor White Farmers
    (Cunninghams)

  3. Poor White Trash
    (Ewells)

  4. Blacks (Calpurnia,
    Robinsons)

There is prejudice from nearly every
tier of this list toward anyone who is underneathe.  Not every character fits into the
generality that the entire town is prejudiced, but to make a generalization, the class
system is mostly built on wealth and education, and most are born into a level where
they will always remain.  Not understanding this unspoken societal class system is why
Miss Caroline has such a hard time on the first day of school.  There are unspoken rules
and boundaries that go with it.


This quote applies to
directly to many of the different people Scout must "consider" as she grows up.  There
are not many characters in the book who are similar to the family she knows.  When
Walter comes over for supper for example, in chapter 3, Scout starts to make fun of him
for pouring mollasses all over his food.  Scout doesn't understand the look from
Atticus, nor the fact that she must finish her meal in the kitchen with
Calpurnia.


Scout grows up in the first tier of Maycomb
society, a group that Atticus belongs to by education and perhaps income, but not
necessarily attitude.  Unlike many people in the "professionals" category, Atticus is
not imposing on his children the attitude that they are better than anyone else. 
Therefore, not only does Walter Cunningham relate directly to this most famous "Atticus
Finch lesson," but nearly everyone else in the town does as
well.

Describe shortly the character Mr. Fielding from the point of view of Aziz.

Aziz is an interesting character because he is very
emotional and flighty. He is somewhat conflicted over his relationship with Fielding. He
realizes in his gut that Fielding is not like the other British, and he likes Fielding,
but he still maintains distance from Fielding. He is both attracted and put off, wanting
to become Fielding's friend, but never sure if it is possible to be his friend. He seems
to enjoy being around Fielding, but sometimes he tries too hard to befriend him and
impress him. Then, he gets impatient with himself for trying so hard. He is curious
about Fielding. He does not understand why Fielding is different
than the other British. He reads Fielding's mail in one chapter because of this
curiousity, but he does not see anything wrong with doing this. He sometimes thinks that
Fielding is too straightforward, which is different from the way Aziz approaches things
- dealing in nuances and indirectness. He is sometimes embarassed when Fielding tells
him things bluntly, not knowing how to react and not feeling comfortable about being as
blunt or as honest.


Aziz often misinterprets Fielding's
motives. After the trial, he is angry at everyone, including Fielding, who ironically is
the only one who believed he was innocent.

In "Dr. Heidegger's Experiment," what happens to the rose?

We are told that the rose is incredibly important to Dr.
Heidegger, as it was given to him by Sylvia Ward to be worn on their wedding day before
her unfortunate death. However, it is also vitally important to the short story, as
Hawthorne uses it symbolically to reinforce the message of this tale. When Dr. Heidegger
throws the rose into the water from the Fountain of Youth, it blooms once
more:



Soon,
however, a singular change began to be visible. The crushed and dried petals stirred,
and assumed a deepening tinge of crimson, as if the flower were reviving from a
deathlike slumber; the slender stalk and twigs of foliage became green; and there was
the rose of half a century, looking as fresh as when Sylvia Ward had first given it to
her lover.



Of course, this
symbolises the change that is about to occur in each of the guests as they drink the
Water of Youth, and it also indicates the reversal in their youth at the end. When it
does fade once more, intriguingly, Dr. Heidegger says about
it:



"I love it
as well thus, as in its dewy
freshness."



Clearly, Dr.
Heidegger is pointing towards the moral of this story - ageing brings its own benefits,
such as reflection and wisdom, which are just as important and valuable as the youth
that his guests are so eager to re-live and waste once more.

Regarding Chapter 3, in what way are Nick and Gatsby similar at this point? Why are they paradoxical?Only chapter 3 based answers please provide a...

One way in which Nick and Gatsby are alike in chapter 3 is
that neither one is careless.  Jordan says to Nick, toward the end of the chapter, "I
hate careless people.  That's why I like you."  Gatsby is very careful in how he
presents himself.  He orchestrates his parties like he's conducting the Philharmonic. 
He brings in lavish feasts with plenty of illegal alcohol.  He brings in people, too. 
He does not drink because he wants to stay in control of everything.  Even his words are
carefully planned.  This is emphasized by his affectation, "Old sport".  The two are
different though, in the reason why each is careful.  Nick is careful because he cares
about others and because he's honest.  He even concludes the chapter with the admitted
realization of his one cardinal virtue - honesty - when he says, "I am one of the few
honest people that I have ever known."  For Nick, being honest equates to carefulness
because Nick does not like to lie to or to mislead people.  He is careful not to do
either.  Gatsby, on the other hand, is careful to hide his true identity and motives. 
His carefulness is required because of his lack of honesty.  He creates a false history
and he does nothing to straighten out the rumors of his past.

In Fahrenheit 451, why does Bradbury intricately describe the river, woods, and sky?

The vivid details Bradbury uses occur at the end of the
novel when Guy Montag has escaped capture by the Hound and society. His escape takes him
swiftly through the town, anticipating capture at any minute, with the Hound closeby.
Within feet of the river, the authorities announce that everyone should open their doors
to search for the fugitive (Montag). When the people all step outside, it is only then
that Montag has reached the river and stepped in. His immersion erases the scent that
the Hound has been following.


It is not just sheer relief
or an adrenaline rush that brings the characteristics of the river so vividly to Montag.
 It is his immersion into nature and freedom that so overwhelm him, and he is like a
newly born creature with his "meeting" of the water. The water is like "raw liquor"
which he drinks in and even snorts up his nose.  he cannot get enough of it. Montag
travels—floating as in a dream—on the water, as the land passes him.  He has left the
horror of reality and moved into what seems unreal: peace and quiet that is a soothing
balm to his soul.


The woods assail his senses as he begins
to walk.  He smells the scent of hay, hears animals and insects, and the rustle of
trees: all away from the oppressive sounds and imprisonment of the city.  And he recalls
a time when he knew a girl who lived in this kind of place, who could put dandelions
beneath one's chin and explain what she saw in the yellow reflection of the
"flower."


And in the sky, he sees stars so multitudinous
that they seem almost overpowering: he cannot remember seeing so many stars, so
brilliant.  The moon is also beautiful, casting its reflected light all around
him.


In all of these things there is beauty, peace and a
frightening sense of freedom. Here Montag becomes acquainted with the world as it truly
is, not as it is "prepared" for him, or explained to him. There is no one controlling
what he sees or thinks or feels.  Life until now has been precise and calculated. He and
his neighbors have not experienced the world except as it has been "homogenized" by the
government.


Bradbury provides these vivid details to convey
the essence of Montag's rebirth into the world. The details flow over the reader as the
images and sensations flow over Montag. All of these things delight Montag and give him
release—and a sense of hope, though even that is not strong yet. The men he meets at the
camp will help him grow stronger in the journey he now undertakes with his newfound
freedom, and release.

Explain how might we think of The Autobiography of an Ex-Coloured Man by James Weldon Johnson as a queer text.

I think that there are few assertions to be made on the
outset.  The primary level of distinction in the work is one predicated upon race and
racial identity.  This is not something that can be whittled away.  Lines such as,
individuals of color "of this country know and understand the white people better than
the white people know and understand them," help to bring this into total focus.  The
idea of the narrator being obsessed with the issue of race and racial identity
throughout the autobiography also helps to bring this into full light.  Yet, I think
that the text can be seen as analogous to groups such as gay and lesbian and
transgendered individuals with the idea of substituting sexual identity for race.  The
notion of seeking to come to terms with being "different" in a society is something that
can help make this work compatible works that analyze what it means to be different in a
sexual sense from the cultural majority.  I think that this might be the only way that
one can see this text as queer, in that we have to replace what is constructed as racial
identity for that of sexual orientation.

Explain what visual techniques are shown in "Unemployment" by Ben Shahn that gives the viewer a sense of belonging or not belonging.

I think that one can see some strong techniques employed
in Shahn's work that help to bring out the theme of belonging.  The fact that all of the
characters in the portrait seem to be looking or staring at the same object reflects a
common link in their experience.  Given the title of the portrait, it might be that they
are looking at their own reality with a sense of despair.  Perhaps, they are envisioning
an end goal that seems so very far removed from their own present consciousness.  In
their shared glares of fixation the viewer understands that their predicament is
understood, is common to all of them, and something where some level of solidarity is
present, consciously or not.  The fact that they all look the same for the most part
helps to also enhance the belonging theme of the work.  There might be some surface
differences in that one might look darker than another or one might have a physical
difference in their appearance.  However, Shahn might be trying to draw the transcendent
condition of their similarity as undercutting all else.

How can you explain the stanzaic and line structure in Sir Philip Sidney's “My True Love Hath My Heart”

This poem by Philip Sidney is a sonnet, so the structure
of the poem is 14 lines, and in this case, it has an Italian Sonnet structure.  You can
see that the first 8 lines (the octet) are broken into 2 4-line sentences. Then the
final 6 lines (the sextet) are the last sentence of the poem.  The rhyme scheme also
helps unify these sections.


In this clever poem, the
speaker (a woman) is explaining how she and her love have exchanged hearts, and that
this act has made them very happy.  This poem takes the almost cliche idea of exchanging
hearts and takes it to the extreme, almost implying a literal exchange of hearts.  The
octet explains how she has his heart and he has hers, and because of this exchange they
are now inextricably joined.


In the sextet she explains
they have each received a wound -- this is an allusion to Cupid, who with his arrow
shots, gives wounds, but those wounds cause love, so they are wounds that ultimately
cause bliss.  The final line repeats the first line, thus reinforcing the theme of the
poem.

"We lived and died together." How does this reflect a cultural insider's perspective, disrupting streotypes about stoic Indians?in The Absolutely...

The idea of suffering together is an element that emerges
from the quote.  The cultural insider point of view that is present is one that reflects
the nature of suffering amongst the Indians was something that could only be understood
by those who endured it.  The notion of the stoic Native America being one who is
separated from the harsh conditions placed upon them is a stereotype that might have
actually empowered the aggressor in continuing to inflict policies that were harmful to
the nature of the Native America.  In such a quote, the reader fully understands this
part of Junior's identity.  Death and suffering are a part of his own consciousness,
something that White society fails to understand.  When Junior goes to a white school,
the experiences of his being an Indian are negated.  Yet, when Junior experiences the
intellectual curiosity that transcends the reservation, the statement's truth might also
be reflexive.  What this means is that part of living and dying together is the hope
that there could be something else. While such a condition binds Native Americans,
Junior's desire to see something else outside of where he is, something outside of death
and suffering, might also be motivating his desire to leave.  In this quote, we see a
statement on the culture, but also in how this could impact Junior and his own
developing sense of consciousness.

In The Odyssey, what reason does Odysseus give for not answering Penelope's questions about his background?

Odysseus, disguised as the beggar, attempts a few thwarts
of this question. At first, he just allows Penelope to tell her story and background
which she hopes would help him begin to tell his own story. Fortunately for him, it gave
him time to connect to something she said. Obviously he cannot tell the truth, he needs
to keep his identity a secret to even her until the suitors are killed. But, he did
think long enough to craft a story about the fact that he had run across Odysseus in his
travels. This mention of her husband distracts her enough that she doesn't really ask
for his background again. He describes Odysseus and tells of his safety. This confirms
for her that he is telling truth because he knew details the common person would not
just know about Odysseus, and then he gave her hope. He didn't have a good reason for
not answering her questions, he just skirted them thinking as a beggar he could be
considered a man of little importance.

Could it be argued that Jefferson laid the foundations for an imperial US and a powerful federal government?

Because Thomas Jefferson was a Democratic-Republican, you
would not think that he would have helped lay a foundation for these things.  However,
you can certainly argued that he did, indeed, lay the foundations for a powerful central
government and an imperial US.


The main argument for this
comes from the fact that Jefferson bought the Louisiana Purchase on his own accord as
president -- he did not ask permission.  He did this even though the Constitution does
not give the president permission to do this.  By doing this, Jefferson set a precedent
that presidents can kind of do whatever they want if it's not clearly unconstitutional. 
He also gained a huge amount of land for the US and started it on its way to being a
huge and imperial country.

Compare and contrast Brechtian and Aristotelian Theatre.

This sounds like an essay topic, so I'll give you a few
points of comparison to get you started.  Please also use the link below to more
information on writing a comparison/contrast
essay.


  1. Probably the most important difference
    between the two is that Brecht wanted his audience to think intellectually
    about the performance that they were witnessing, while Aristotle argued
    that audiences, especially those witnessing a Tragedy, should be drawn in
    emotionally, experiencing the tragic circumstances along
    with the hero of the play.

  2. Aristotle did not actually
    write or produce theatrical performances, he was a philosopher and offered theoretical
    ideas about the nature and purpose of drama in his work Poetics
    Brecht was a director, writer and producer of his own theatrical productions.  So, while
    Aristotle presented theoretical ideas about theatre, Brecht
    presented practical applications or stagings of actual
    performances.

  3. Aristotle proposed that the drama
    (especially Tragedy) is a journey of a main character to a cathartic self-awareness. 
    For Brecht, dramatic theatre exists as a vehicle to create social change, not to reflect
    the internal workings of an individual soul.  So, Aristotle's focus was
    man's internal life, while Brecht's focus was on
    the external, the social
    order
    .

his Poetics, and Brecht, plus some tips for creating a

Determine f(x) if 2*f(x) + 3*f(1-x) = 4x - 1

We conclude that the function we have to determine is a
linear function, because the result of the sum of the functions is a linear function 4x
- 1.


We'll substitute x by 1-x in the given
relation.


2f(1-x) + 3f(x) = 4(1-x) -
1


We'll remove the brackets form the right
side:


2f(1-x) + 3f(x) = 4 - 4x -
1


We'll combine like
terms:


2f(1-x) + 3f(x) = 3 - 4x
(1)


2*f(x) + 3*f(1-x) = 4x - 1
(2)


We'll eliminate the unknown f(1-x). For this reason,
we'll multiply (1) by 3 and (2) by -2:


6f(1-x) + 9f(x) = 9
- 12x (3)


-6f(1-x) - 4f(x) = -8x + 2
(4)


We'll add (3) +
(4):


6f(1-x) + 9f(x) - 6f(1-x) - 4f(x) = 9 - 12x - 8x +
2


We'll eliminate and combine like
terms:


5f(x) = -20x + 11


We'll
divide by 5:


The function
is:


f(x) = -4x +
11/5


Another method of solving the problem
is to consider the linear function:


f(x) = ax +
b


f(1-x) = a(1-x) + b


f(1-x) =
a - ax + b


We'll re-write the expression 2*f(x) + 3*f(1-x)
= 4x - 1


2ax + 2b - 3ax + 3a + 3b = 4x -
1


We'll combine like
terms:


-ax + 3a + 5b = 4x -
1


The expressions from both sides are equal if the
correspondent coefficients are equal.


-a =
4


a =
-4


3a + 5b =
-1


3*(-4) + 5b = -1


-12 + 5b =
-1


5b = 11


b =
11/5


f(x) = -4x +
11/5

After how many years will the maximum payout be less than the premium, losing money by continuing with the policy in the scenario below?A machine...

The annual premium paid is 10% of the new value = P/10 ,
where P is the new value of the machine.


The  value of the
machine due to depreciation  is 1/2 of new value for every two years. Thus the machine
value at any year becomes sqrt(1/2) of its pevious year value.  The new value of the
machine is P . So after n years the value of the machine becomes  {sqrt(1/2)} ^n * P=
P/(2^(n/2)).


So the maximum pay out by the insurance
company  at any year = machine value at that time (or year) =
P/(2^(n/2)).


So it is required to determine when the
maximum pay out by the insurance company becomes less than the annual premum
.


Therefore to determine n such that P/2^(n/2)  <
P/10.


Divide by P and cross
multiply:


10 <
2^n/2.


log10 < (n/2)
log2.


2 /log2 > n.


Or n
> 2/log2 .


Clearly for n = 6.64 ,  1/2(6.64/2) =
0.100226.. > 1/10.


For n = 6.65 , 1/2^(6-65/2) =
0.9979 < 1/10.


Therefore  between the year 6 and 7 
(or between 6.64 years and 6.65 years, or in the 8th month  after 6 years) the  maximum
 insurance becomes less than the annual premium. So making the annual payment of premium
is a clear loss from the 7th year onwards.

Solve 5x + 6y + z = 9, 6x + 3 y = 6, 2x + 6y + z =4

5x+6y+z=9...........(1)


6x+3y
=6................(2)


2x+6y+z=4
.................(3).


The 2nd equation is free from
z.


So we eleminate z between equations (1) and (3) by
Eq(1)-eq(3) which also eliminates y. So we solve x
:


(5x+6y+z) - (2x+6y+z) = 9 - 4 =
5


3x = 5.


x =
5/3.


Substitute x = 5/3 in
eq(2):


6x+3y = 6. Or 3y = 6-6x = 6-6(5/3) = 6-10 =
-4.


3y = -4.


y=
-4/3.


Substitute x = 5/3 and y =-4/3 in
(1):


5x+6y+z =
9


5(5/3)+6(-4/3)+z = 9


25/3
-24/3 +z = 9


1/3 +z = 9


z =
9-1/3 = 26/3


Therefore x = 5/3 , y =-4/3 and z
=28/3

What is important for students to know about Act II, scene ii, in Romeo and Juliet, and how can I, as their teacher, make them learn it?

I don't believe that you can make anyone do or learn
anything.  As the old saying goes: "You can lead a horse to water, but you can't make
him drink."  Maybe it would be helpful for you to focus on the things about the scene
that you really like, the things that you think are very neat or cool, so that your
enthusiasm might be contagious to the students?


Here are
some things about the scene that, for me, make it an exciting and interesting
one.


  1. The scene opens with tons of dramatic
    suspense, created because Romeo is in the garden of his enemies.  Will he be
    discovered?  Will he have to fight one of his Capulet
    enemies?

  2. Juliet is, in terms of her language, a much more
    straightforward, direct, and "masculine" character.  It's Romeo who has all the very
    flowery and romantic descriptions of things.  These characters (who go against the
    masculine and feminine stereotypes) might have been created by Shakespeare to have fun
    with the fact that he knew young men of almost the exactly the same age would play these
    two characters.  Have your class read parts of the scenes, interchanging guys and gals
    reading Romeo and Juliet.

  3. Talk with your students about
    the fact that, except for the light in Juliet's window, the scene is meant to be taking
    place in the dark.  This means that, at least at first, Romeo can see her, but she can't
    see him.  Discuss how this affects the scene and at what point in the text it might be
    that Juliet finally sees Romeo.

  4. Some of this text is the
    most famous in all of the English language.  For example "Wherefore art thou, Romeo?" is
    very famous, but often erroneously assumed to mean "Where are you, Romeo?"  So, it might
    be illuminating to pick out some of the more famous lines and examine them for their
    images and correct meanings with your
    students.

Again, the key is really to find the
parts of the scene that interest and excite you.  This will give you the greatest chance
of success with teaching the scene to your students.  For more about "the balcony
scene," please follow the links below.

Describe the social structure of the community in Silas Marner.

The clearest information we are given about the social
structure of Raveloe in this fascinating novel is in Chapter Three, which introduces us
to the "head" of Raveloe. Of course, as with any village, Raveloe consists of a mix of
different groups of people, each having their own social standing. Thus there are the
landed gentry, at the top of the social ladder, with other various groups taking their
place below them until you reach the very poor. However, Chapter Three begins with an
introduction to the Cass family:


readability="9">

The greatest man in Raveloe was Squire Cass, who
lived in the large red house, with the handsome flight of stone steps in front and the
high stables behind it, nearly opposite the
church.



We are likewise told
in this chapter about the relationship between the rich and poor of
Raveloe:


readability="12">

...the rich ate and drank freely, and accepted
gout and apoplexy as things that ran mysteriously in respectable families, and the poor
thought that the rich were entirely in the right of it to lead a jolly life; besides,
their feasting causes a multiplication of orts, which were the heirlooms of the
poor.



Thus Raveloe exists
with the head of its social structure being Squire Cass, with other members of the
landed gentry who live a fine life. There also exists the poorer members of the
community who do not begrudge their supposed "betters" the life they
lead.

Analyze the poem "The Negro Speaks of Rivers" by Langston Hughes.

The rivers which Hughes describes follow the history of
human evolution,beginning with the Euphrates, where human civilization is believed to
have begun, to the African rivers of the Congo and Nile, and eventually to the
Mississippi, where Africans were brought as slaves to America. Hughes’ poem speaks to
the deep cultural history to which W. E. B. DuBois often alluded as an undiscovered
strength of African-American culture.


Rivers have specific
geographic boundaries, and yet by naming the rivers and their locales, the speaker
communicates the universal, boundless nature of the human soul. The title informs the
reader that the speaker is African American,though the racial identity is not overtly
mentioned in the poem itself. The effect of this approach is to suggest that the
connection of spirit and soul that this “I”shares with the earth is organic, even
prehistoric.


The incidents, including references to bathing
in line 5, building a hut on the Congo in line 6, pyramids in line 7, and singing of the
slaves in Mississippi in response toLincoln’s Emancipation Proclamation, all evoke the
active role and contributions of African Americans throughout history. The chronology of
these stanzas reinforces not only the historical participation of the“Negro” but the
spiritual depth he has acquired in the long journey from slavery to
freedom.

Determine the definite integral for y=x+1/x. x=1 and x=3

The definite integral is calculated using Leibniz-Newton
formula.


Int (x + 1/x)dx = F(b) - F(a), where a = 1 and b =
3


First, we'll determine the result of the indefinite
integral:


Int (x +
1/x)dx


We'll use the additive property of
integrals:


Int (x + 1/x)dx = Int xdx + Int
dx/x


Int (x + 1/x)dx = x^2/2 + ln x +
C


The resulted expression is
F(x).


Now, we'll determine F(b) = F(3) and F(a) =
F(1):


F(3) = 3^2/2 + ln 3


F(3)
= 9/2 + ln 3


F(1) = 1/2 + ln
1


F(1) = 1/2 + 0


F(1) =
1/2


We'll determine the definite
integral:


Int (x + 1/x)dx = F(3) -
F(1)


Int (x + 1/x)dx = 9/2 + ln 3 -
1/2


We'll combine like
terms:


Int (x + 1/x)dx = 4 + ln
3

What is the historical background that influenced Dickens' writing of Great Expectations?

Living in the Victorian Age in which industrialization was
changing society, Charles Dickens felt that society in England was a prison.  In the
rural areas there were landlords, the owners of large farms, and farmers and common
laborers who owned no land, but merely existed on a subsistence level by working on the
large farms.  With the invention of the steam-powered engine, thrashing machines took
the place of many of these laborers.  Consequently, the poor rural people flooded the
city of London where they, along with the other poor of London, sought work in the
factories.  In their efforts to survive, these people sent their children to work as
well.  Since their jobs were unskilled laborer jobs and there were no labor laws of any
kind in England at that time, the poor were condemned to poverty
forever.


Having had a father placed in debtors' prison and
having had to work in a blacking warehouse as a boy himself, Charles Dickens was most
sympathetic to the poor, a class who was ignored by what he perceived as a frivolous
upperclass who controlled all the wealth.  In fact there was only one major bank, the
Bank of England, which dealt mainly with government contracts because businessmen
conducted their financial dealings privately among themselves.  Since there was little
hope for social mobility, many of the poor who sought their fortune during the
Industrial Revolution found themselves in workhouses and prison, or they turned to
crime.  Since money was made in London, criminal activity increased there. (Magwitch is
one of the poor who survives by petty crime.)


As
higher-level workers in factories and merchants prospered from the industrialization, a
new middle class emerged (Uncle Pumblechook is an example) and the need for banking
arose.  Banks, thus, became more numerous as the need for borrowing for new businesses
arose.  (Pip's procuring a job for Herbert is made possible by this growing banking
business.)


It was not until 1860 that the railroad
connected the city to the rural areas of England. (This is why Pip must take the
stagecoach to the Boar's Inn whenever he returns home.)

How did the railroad industry pioneer the economic developments of the late nineteenth century? (In the U.S.)Remember, economic developments!

I would say that the major way in which the railroads
acted as pioneers was in relation to building the big businesses that came to typify the
late 19th and early 20th centuries.  As one of the books I teach from says, railroads
were the first of the truly big businesses.


As the
railroads got so big, they had to pioneer new ways of doing business.  Most importantly,
they were the first companies to get so large that they needed complex bureaucracies to
keep them running efficiently.  This was the beginning of the new trend toward large
companies that had significant numbers of white collar bureaucrats working for
them.


One example of how the railroads had to change things
is not really economic, but it illustrates the point.  It was only because of the
expansion of railroads that the US got standardized time zones.  This was because the
railroads were big, complex businesses that needed to really know for sure that each of
its parts was in agreement as to what time it was.  From that came the time
zones.


So the railroad expansion brought with it the
organization and rationalization of the activities of huge
businesses.

In The Merchant of Venice, what is the wisdom of the conditions of the will laid by Portia's father?

This is a great question - I don't think many women today
would like to be in the same situation as Portia! However, as Bassanio mentions to
Antonio in Act I scene 1 about the lady "richly left", it is clear that the inheritance
that Portia has received can be viewed as much as a curse as a blessing. Portia herself
in Act I scene 2 certainly bemoans her situation to Nerissa, complaining that by her
father's will she is not able to choose her husband - only if they successfully pick the
right casket with her picture in it will they gain her hand in marriage. Note what she
says about her longing to be able to choose:


readability="11">

O, me, the word "choose"! I may neither choose
who I would nor refuse who I dislike; so is the will of a living daughter curbed by the
will of a dead father. Is it not hard, Nerissa, that I cannot choose one nor refuse
none?



Portia here points to
the irony of her situation - her will is curtailed by the will of her "dead" father,
although he is long gone and she is still alive. She also points out the lack of freedom
she has - for not being able to choose also means she is not able to
refuse.


However, in response to her grumblings, it is
Nerissa who actually answers your question by explaining the wisdom of Portia's father's
conditions:


readability="13">

Your father was ever virtuous, and holy men at
their death have good inspirations; therefore the lottery that he hath devised in these
three chests of gold, silver, and lead, whereof who chooses his meaning chooses you,
will no doubt never be chosen by any rightly but one who you shall rightly
love.



Nerissa sums up the
wisdom of Portia's father's actions. As a "virtuous" man, he can be trusted so that the
"lottery" that he created will only allow somebody who is suitable and worthy for his
daughter's hand to succeed. Herein lies the wisdom - Portia's father has designed a test
to weed out the suitable from the unsuitable, ensuring that the person who triumphs is
of a suitable moral character for his daughter.

Much of the conversation seems to be about trivial things. What purposes does this conversation serve?"Hills Like White Elephants"

As is so typical of Ernest Hemingway's minimalist style,
much of the meaning of "Hills Like White Elephants" comes from what is not said and what
lies beneath the surface--his renowned "iceberg effect."  Often a second reading of his
stories reveals more to the student since knowing the outcome assists in finding how it
came about.  However, in this story, even the outcome is
unresolved.


Nevertheless, it is this ambiguous conclusion
that leads the reader to an understanding of the character of the man who is myopic in
his relationship with Jigs, the girl.  For instance, while the couple are waiting for
the train to Barcelona and sit at a table, Jig "looks off at the line of hills" and
reflectively notes that they look like white elephants, but the man replies without
interest without pausing in his drinking of a beer:


readability="9">

"I've never seen one," the man drank his
beer.


"No, you wouldn't
have."


"I might have," the man said.  "Just because you say
I wouldn't have doesn't prove
anything.



He becomes angered
at the suggestion that he cannot expand his thinking, a contention made relevant in the
ensuing conversation as Jigs tries to escape her thoughts by drinking absinthe, known
for its psychoactive properties:


readability="13">

"It tastes like licorice," the girl said and put
the glass down.


"That's the way with
everything."


"Yes," said the girl.  Everything tastes of
licorice.  Especially all the things you've waited so long for, like
absinthe."



The man, "who
lacks imagination" as a character from another of Hemingway's stories describes such a
man, dismisses her reflections.  Likewise, he seeks to dismiss the subject of his desire
for Jig to have an abortion so that they can "...be fine afterward.  Just like we were
before."  Repeatedly, the man speaks of his concern for Jig--"if you don't want to you
don't have to."  But Jig's knows that things will be
different:


readability="8">

"...But if I do it, then it will be nice again if
I say things are like white elephants, and you'll like
it?"



Another aspect that
develops the meaning to the apparently trivial conversation is the few lines that
Hemingway puts between this dialogue.  For example, towards the end of the story, the
man tries to convince Jig by saying, "But you've got to realize---" and she abruptly
responds with "I realize"; however Hemingway narrates that she looks across at the hills
on the dry side of the valley and the man looks at her and at the table.  These actions
of the girl and the man indicate their points of view on their serious topic.  For, Jigs
sees beyond to a dry, dispassionate relationship, while again the man is myopic and
selfish.  Thus, there is no resolution to their conflict since there is no change in
character.

Is a one page quote too much for a six page essay? i found some material from an articles that supports my work well but the parts i nees...

If your paper is only 6 pages long, then that quote would
be 15% of the text -- and it isn't YOU!.  Good research uses sources like what you have
found, and selects the most salient points to quote.  Once you have the quote or
paraphrase, then YOU need to explain what you have written and connect it to whatever
the topic of your paper is.  Your teacher wants to know what you think first and
foremost -- not what other people think.  Your essay needs to reflect you -- not be a
summary of others. 


If this is a literary analysis paper,
consider the idea and  examples from your source, but then also discuss additional
examples that you found in the text. 


On a side note, be
sure that you use proper documentation of ANY ideas that come from outside sources,
whether you use direct quotations or paraphrases.  Just putting someone else's idea into
your own words does not make the idea yours -- that is still plagiarism. 

How do I write a letter to a Spanish friend?I have to write a letter to my spanish freind descibing my spanish classroom. i have to...

Yikes!


It is not difficult,
actually. All you have to do is FIRST form the sentences using the parts of the
classroom. What your teacher wants is to know whether you can grasp the concept of using
your nouns BEFORE your adjectives which is the biggie in learning Romance languages such
as French, Spanish, and Italian.


Ok: First, write down the
parts of the classroom that you need to describe- **We couldn't possibly do it for you
unless we have seen your classroom**. Try something such
as:


La bandera de los Estados Unidos esta en la parte
derecha del salon.


El escritorio de la maestra esta al
frente del salon y al frente de los estudiantes.


Los
estudiantes se sientan de frente al escritorio de la
maestra.


La pizarra es blanca y
grande.


Las ventanas son grandes y puedes ver afuera hacia
el patio.


As far as the letter to your friend goes, ask:
Como es tu salon? *Use the accents*


Most importantly,
always begin your letter the way a Spanish person
would:


Querido amigo,


Como
estas?  Yo estoy muy bien! Dejame contarte de mi nuevo salon de clases. Es muy bonito!
Lo voy a describir en esta carta. Luego me dices como es tu salon de clases.
Bien?


And then begin to describe. Hope it
helps!

How did one achieve upward mobility in the tribe?

In Things Fall Apart, a male member
of the Igbo tribe may advance in terms of wrestlers thrown, cowries collected, wives
obtained, children sired, titles garnered, heads taken in war, and yams harvested.
 Males were thus upwardly mobile within the tribe; females, however, could only be
mobile within the family, depending on which wife they were (by
age).


In the novel, males can attain upward mobility
through great physical labor in the fields, at war, and during the wrestling matches.
 Females have limited mobility and can only hope to marry a titled male.  Luckily, a
wife will give birth to several male children who survive.  Only then will she be
granted her own obi and status among the other
wives.


Okonkwo, for example, has three wives and several
children who live in separate obis on his compound.  He has an obi full of yams for
which he has had to toil mercilessly.  He has limited cowries (shells used for money)
because he has had to repay his father's debts.


Most
importantly, Okonkwo has two titles (and two more to go).  These are the main status
symbols in the tribe; they are like stars on a general.  Also of note are Okonkwo's five
heads taken in battle.  And, don't forget,  he first achieved fame by throwing the Cat
during a wrestling match.   Having been the son of an agbala
(titleless male), Okonkwo's hard work has allowed him to move up the social ladder of
the tribe to become one of its most respected leaders.

1) Explain datatypes in c++. 2) Explain declaration & branching control statement in c++. 3) Explain object oriented methodology in c++.

1) A datatype in any programming language defines the type
of data a variable will hold in memory.  The basic datatypes in C++
are:


char --> character (such as "a" or b"), or a
small integer (-128<n<127 or 0<n<255)
int
--> integer (whole numbers)
bool --> boolean (i.e. true or
false)
float --> floating point number (can have decimal numbers up to
7 digits)
double --> double precision floating point number (can have
decimal numbers up to 15 digits)


2) Control statements in
programming control what pieces of code will be executed
when.


Branching control statement --> depending on
the condition, different code will be executed.  Examples of branching control
statements are if and switch statements


Declaration control
statement --> executes code while the conditions of the statement are being met,
these are typically loops: for, while etc.


3) Object
oriented program essentially models computer language as easy to decipher thinking. 
Unlike machine code which is like learning a new language entirely, in object oriented
programming it reads and flows like thought: if this, then do that, for this, do that,
etc.

What is Finny's theory about the war ?no

In Chapter 8, Finny tells Gene that the "war stuff" is a
myth.  He states that American is not truly "in a state of war with Nazi Germany and
Imperial Japan."  He claims, "there isn't any war." So, he convinces Gene that he needs
to start training for the Olympics.


His theory is that the
war is fake, a conspiracy concocted by "fat old men" who don't want the younger
generation "crowding them out their jobs."  These fat old men are enjoying themselves
while the young men are fighting this pretend war.


Later he
confesses to Gene that he never believed this theory.  He knew there was a war.  He
created this story because he had tried to enlist but because of his injury was unable
to.  Gene's telling Finny that he would be no good in a war because he was not a killer,
was not ruthless, was one of many truths that the two young men confront in the
novel.

A box is dragged along the floor. The rope that is acting on the box makes an angle A to the floor. How much force is being used to drag the box ?

In the rope occurs a tension that is dragging the box and
tends to lift the box. If the angle made by the rope to the floor is smaller, the force
that is dragging the box will be greater. If the rope is parallel to the floor, the
lifting component won't exist, at all.


The component of the
tension that dragging the box is the horizontal
component.


F horiz. = F*cos
a


If the tension in the rope is 300 N and the angle made by
the rope to the floor is 30 degrees, the horizontal component
is:


F horiz. = 300 N*cos 30


F
horiz. = 300*sqrt3/2


F horiz. = 150sqrt3
N


The vertical component of the tension, the
lifting force is:


F vert =
300N*sin30


F vert =
150N


Now, we must take in consideration the
friction that brakes the box when it is dragged on the
floor.


The friction is opposite to the horizontal component
of the tension from the rope, when the object is moving at constant
speed.


Friction = - F
horiz.


Friction = -150sqrt3
N

In Hamlet, what literary devices can you identify in the following passage? Please help me find metaphors, synecdoche, images, similes. It is...

a) Metaphors are comparisons that do not use the word
"like" or "as."  Some examples:


"O, what a rogue and
peasant slave am I."  Hamlet is not really a slave; in fact, he is a prince.  He means
to say that he is acting like a peasant slave who lacks
courage. 


 "Why, what an ass am I!"  Hamlet is not really a
donkey.  He means to say that he is acting foolishly, like a
donkey.


b) Images.  The two metaphors above can also be
considered examples of imagery; they cause us to picture slaves and jackasses in our
minds.  Other images are:


"drown the stage with
tears";


"I should have fatted all the region kites/With
this slave's offal" (I should have fed all the hunting birds in the
region
With my body’s decaying flesh);


c) Similes
are comparisons that use the word "like" or "as."  Some
examples:


"Yet I...peak like a John-a-dreams" (shrink from
my task of revenging my father's murder like a dreamy
fellow);


"I...must...fall down cursing like a very drab, /
Menial servant in the kitchen."


d) A synechdoche is a
figure of speech in which a part is used to represent the whole (abc for alphabet) or
the whole represents a part (Boston won the World Series).  The term is also used for
other substitutions, such as the object contained for the container ("I was injured by
some pickles" rather than "I was injured by a can of pickles), and the action instead of
the actor.


This passage contains an example of the last
type of synechdoche:


readability="7">

Because murder, although it is silent, will
speak
With its own most miraculous
organ.



Hamlet does not mean
that "murder" can speak.  Rather he means that the person who committed the murder,
Claudius, can be made to speak by having him witness a play that is "something like the
murder" of Hamlet's father.

In A Separate Peace how is Gene directly affected by the war?

Gene is an interesting one, because one main point of the
novel is that the war impacts him less than his experiences with Finny did.  Gene gives
an entire analogy at the end of the book where he shows that the war was hard, but that
before he ever got to the battlefield, he had fought his own personal war with himself
over thre Finny situation.  During his time at Devon, Gene had confronted his
insecurities with himself, his feelings of jealousy over Finny's popularity and seeming
ease in life, and dealt with his own morbid ability to hurt and damage others.  The war
is so traumatic for people often because they have to face the reality that they are
capable of killing and injuring other human beings who they don't really have anything
against personally.  Gene came to that realization before he ever joined the war; he
tried to hurt his friend.  He was capable of great evil towards his good friend.  In the
third to last paragraph of the book, Gene says,


readability="7">

"I never killed anybody and I never developed an
intense level of hatred for the enemy.  Because my war ended before I ever put on a
uniform; I was on active duty all my time at school; I killed my enemy
there."



So while other boys
had to face that realiy on the battlefield, Gene had already fought with himself over
that and come to terms with it.  Yes, the war does impact him; for example, it gives him
a horrible experience with Leper, it impacts his life at Devon as troops and supplies
for the war move onto campus, and it takes many of his friends away from him.  However,
Gene struggled with the issues that war raised before he ever got to the real war.  I
hope that those thoughts helped; good luck!

What three elements of poetry contribute to the message in the poem "Death Be Not Proud"?

John Donne's Holy Sonnet X, which has
come to be called "Death Be Not Proud" because of its theme and repetition of the
phrase, exhibits several elements of poetry:


METER AND
RHYME 


First of all, since poetry has
been defined as "literature in a metrical form," it is apparent that the meter and rhyme
of Donne's famous verse serve well to contribute to its meaning, an attack upon the
ineffectual tyrant of death.  The meter, the rhythm and rhyme are balanced and strong,
underscoring Donne's assertive castigation of
death.


METAPHYSICAL
CONCEIT


The metaphysical conceit creates elaborately
dissimilar concepts and ideas and images which startle the reader into understanding
that although death comes ultimately, its effect is not as terrible as one may imagine,
for death is not in control of circumstances; it is but a "slave to fate, chance, kings,
and desperate men."  And, of course, eternal life conquers
death.


PERSONIFICATION


Death
has been personificed as the grim reaper; at other times as an angel with black wings
and a net, and still other times as a fierce horseman who carries a skull.  Donne
suggests these images of death with such words as "thou dost overthrow," "and soonest
our best men with thee do go," and "dost with poison, war, and sickness
dwell."


PARADOX


After
suggesting the known images of death and their dangerous acts, Donne counters the fear
that the personification of death connotes by stating
paradoxes:


readability="13">

 For those whom thou think'st thou dost
overthroe,


Die not, poor death, not yet canst thou kill
me


From rest and sleep, which but thy pictures
[images] be



Strengthening his
argument that death has no real power over the human soul which "wakes eternally," Donne
ends with his final paradox: 


readability="5">

And death shall be no more. Death thou shall
die.


If there is a net nonzero force on a moving object, is it possible for the total work done on the object to be zero?

By definition, work equals to zero when the force acting
on the object acts on it perpendicular to the direction of its movement.  The easiest
way to conceptualize this effect is with uniform circular motion, and more specifically,
centripetal force.  With centripetal force, the force is directed away from the centre
of the motion while the object moves perpendicular to it in a circular
arc.


Another situation in which work is zero despite a
nonzero force is when the displacement of the object is zero.  This is seen in the
equation of work:


W = F * d = F * 0 =
0


Pushing against a wall or an object sitting on a surface
are examples of this kind of zero work with a nonzero force.  When you push on a wall
you are exerting force; however, the wall does not move.  When an object is sitting on a
surface, the surface exerts a force upwards on the object; however, the object exerts an
equal force in the opposite direction, and a result, the object does not
move.

About the Prime Interest Rate: How high do you predict it to rise within the next 3, 4 and 5 years, and why?

The prime interest rate or prime lending rate (PLR) is the
rate at which banks lend funds to the clients they consider most credit worthy and from
whom they expect no defaults in repayment. This is not to be confused with the Federal
Funds Rate, which is the rate for loans betweens banks. Sometimes this is also called
the href="http://wheatoncollege.edu/admin/sfs/loans/terms.html">Prime
Rate
.


This has been kept at a very low rate of
3.25% to facilitate the economic development and encourage the creation and expansion of
new industry in the US. Unemployment in the US is still quite high and though it is
trying to find its way out from the economic turmoil that has affected it in the past 2
years it has still a long way to go.


Increasing the PLR can
disrupt this recovery, though the extremely low rate at which it is right now is also
not very good for the economy in the long run .


I think
that within the next 3 years the economy will recover sufficiently to allow the PLR to
be brought back to its earlier levels of 5% that it was before the economic meltdown. It
will remain constant once that is done.

What is the final velocity in the following scenario?A body of mass 16 kg travelling to the right at 5 m/s collides with a body of mass 4 kg...

In a perfectly inelastic
collision:


M1*v1 + M2*v2 = (M1 +
M2)*vf


Here M1 and M2 are the masses of the bodies
colliding, v1 and v2 are their initial velocity and vf is their final
velocity.


Now, in the problem it is given that the body of
mass 16 kg is travelling at 5 m/s towards the right. It collides with a body of mass 4
kg travelling at 5 m/s towards the rest.


Therefore we can
use


M1*v1 + M2*v2 = (M1 +
M2)*vf


=> vf = (M1*v1 + M2*v2)/(M1 +
M2)


=> vf = (16*5 -
4*5)/20


=> vf =
60/20


=> vf = 3
m/s


The final body made up of the bodies that
collided with each other moves at 3 m/s towards the
right.

Why is the kiss considered a monumental moment in The Three Sisters?

The kiss that I assume you are referring to is between
Masha and Vershinin in Act IV.  These characters have fallen in love with each other,
even though they are both married to other people.


In Act
II, Vershinin declares his love for Masha in a brief scene in which the two are alone
onstage.  The play is actually crowded with characters, and a two-person scene is not a
very common occurrence in it.  A few scenes later, in Act III, Masha declares to her
sisters that she and Vershinin are in love with each other, much to her sisters'
horror.


So, the kiss comes after all of this, not during. 
Vershinin is in the army and leaving in Act IV.  He is saying goodbye to Masha and Olga
and, in my stage directions, there is "a prolonged kiss" between Masha and
Vershinin.


It is significant in these
ways:


  • It comes not in a moment when they are
    alone onstage, but when Masha's sister Olga is also there.

  • It does not signal the beginning of a love affair, but
    rather the ending of it.  Vershinin will leave, and by his words to Masha, it seems
    clear that he does not intend to see her again.

  • It is the
    only kiss that they share in the play.

Up until
Vershinin's departure, it appears that Masha's affair with him has been purely
intellectual and emotional.  It is not until the affair is over that they share a kiss. 
This irony is at the heart of this action's importance.

How did the growth of the nationalism affect the Balkans?

It would be helpful if you could tell us which historical
period you are asking about.  I am guessing that you are asking about the time soon
before WWI.  During this time, the growth of nationalism made the Balkans a "powder keg"
that would blow up and help cause WWI.


In the time just
before WWI, the Balkans were mainly part of the Austro-Hungarian Empire.  The rulers of
this empire were ethnic Germans while most in the Balkans were ethnic slavs.  For this
reason, the Slavs were unhappy as part of the empire.  Their attempts to form
nationalist resistance movements caused a great deal of trouble.  This culminated with a
nationalist killing the Archduke and starting WWI.

What is the significance of Tom Robinson's trial in To Kill a Mockingbird?

The trial of Tom Robinson is of great significance in
To Kill a Mockingbird.  In the novel, Atticus Finch teaches his
children, Scout and Jem, that they are not to shoot mockingbirds, since mockingbirds
represent only purity and beauty; the birds do not harm anyone and only give beauty in
the form or song.  The trial of Tom Robinson is symbolic of the killing of a
mockingbird, which is (in turn) symbolic of the destruction of
innocence.


Tom Robinson, is found guilty of the rape of
Mayella Ewell, despite his actual innocence.  The reason for the guilty verdict lies in
the prejudice of those around him.  As a black man, he is assumed to possess fewer
morals and less innate goodness than the white citizens of Maycomb, including Bob
Ewell.  When Tom Robinson dies as a result of attempting to escape the prison in which
he never should have been placed, it is a direct reflection of the theme of the
destruction of innocence.

What are the main aspects of evil and chaos associated with Macbeth's rule?Macbeth’s rule marks a period of chaos and cruelty in Scotland. Only...

Macbeth usurps the throne and his rule in Scotland is one
of tyranny and chaos. After having usurped kingship, Macbeth's sole efforts are to
ensure his safety and to hold on to power. He goes from fear to fear, passing sleepless
nights, unleashing a reign of terror consisting murder and bloodshed. He appoints
murderers to eliminate Banquo and his son, Fleance, in a bid to invalidate the prophecy
with regard to Banquo's issues becoming future kings. Banquo is put to death with
'twenty trenched gashes' on his head, though Fleance escapes. He sends killers to the
house of Macduff even after having known that Macduff fled to England. The killers
terminate Lady Macduff, the children and all members of the family. Ever since the
failed coronation banquet, the Scottish nobles begin to desert Macbeth, and they refer
to him as the 'tyrant'. Macbeth's rule is marked by all sorts of terror and strong-arm
tactics being unleashed, men being labelled as traitors and killed, widows howling and
orphans crying, and the whole of Scotland being soaked in blood.

Find the percentage profit (on selling price) if the cost price = $405 and selling price = $615?

To determine the percentage of
profit:


The cost price = $405
(given).


Sold price = $ 615
(given).


This sale gives a profit as the selling price is
higher than the cost price.


Therefore the amount of profit
= selling price - cost price = $(615-405) = $210.


Therefore
the percentage of profit = (amount of profit/cost pice)100 = (210/405)100 = 21000/405 =
1400/27 = 51.85%.


Therefore , the percentage of profit in
this sale is 51.85%.

In Heart of Darkness, what is significant about this quote? "The word "ivory" hung in the air. You would think they were praying to it."

Everything that is happening in the Congo stems from the
ivory trade. I believe this passage comes toward the end of the story in talking about
Kurtz and his compound. Kurtz has fallen victim to the ivory trade. It has taken over
his life and his greed for it has overpowered him so much so that he has people praying
to it for him and with him. Kurtz was smart enough to be able to brainwash the natives
into working for him, but he was unable to self-regulate and therefore, everything that
is at his compound is geared toward the ivory. Marlow, on the other hand, didn't come to
the Congo to get ivory, so he can keep his mindset based in reality. He was sent to save
Kurtz and bring him back, but he finds that that is impossible.

What is the relationship between inflation and stagflation?

Basically, inflation is one part of stagflation.  But
inflation, all by itself, is not the same thing as
stagflation.


Inflation is when the general level of prices
goes up in a country's economy.  This is not the price of one specific thing -- it is
the average price of all things.


Stagflation is when high
levels of inflation happen while the economy is "stagnant."  This means that the
economy's real gross domestic product is not going up (in other words, the economy is in
a contraction with stagnant or decreasing business activity).  Inflation with
contraction is not usually supposed to happen, but sometimes it
does.


So the relationship is that inflation is one of two
things that make up stagflation, contraction being the second
thing.

What is the volume of the cylinder made of a 8*12 sheet rolled longside?

We have a rectangular sheet with length = 12 and width =
8.


The rectangle is rolled long-side to shape a
cylinder.


Then the height of the cylinder will be the
length of the rectangle= 12.


==> The height (h) =
12.


Then, the width of the rectangle will form the
circumference of the base.


==> The circumference C =
8.


Now we will calculate the
volume.


We know that the volume v = r^2 * pi * h where r is
the radius of the base.


But we have C =
8


==> C = 2* pi * r =
8


==> r= 8/ 2*pi = 4/pi = 1.27 (
approx.)


Now we will substitute into the
volume.


==> V = r^2 * pi *
h


==> V = ( 4/pi)^2 * pi *
12


          = 16/ pi * 12 =
61.12.


Then, the volume of the cylinder is
61.12 cubic units.

How does a pressure cooker work?

The basic principle of a pressure cooker is that the
boiling point of water increases with the pressure experienced by the water and the
steam produced from the steam. Thus the pressure cooker is designed to control the
escape of steam generated from the water inside the cooker. When the steam is not
allowed to escape from the pressure cooker freely, its temperature as well as that of
the water increases. Thus the temperature inside the pressure cooker is several degrees
above the 100 degrees C., the boiling point of water at normal atmospheric
pressure.


The higher temperature of the water in the food
being cooked as well as the steam fills the entire pressure cooker completely, helps to
heat and cook the food inside the pressure cooker evenly and
quickly.


The pressure cookers are designed with systems of
outlets for the steam which open only when the pressure of stem reaches a minimum level.
This allows part of the steam in the pressure cooker to be released from time to time to
prevent the pressure inside increasing to unsafe levels.

How sincerely concerned are the townspeople of Salem for the souls of Hester & Pearl?

The settlement's sentiment towards everything is meant to
be hypocritical and to hold double standards. All through the novel we see how the
elders rule while one of their own impregnated a woman and left her to her disgrace. We
see how they all cry "witch" while allowing a self-confessed witch and necromancer live
among them in an even better status than Hester. In all, the entire town is allegorical
of how the sins of the people require a scapegoat so that society can feel better about
itself.


Nobody cared about Hester and Pearl- all they
needed was a pariah, or scapegoat that they can blame, use as an example, talk bad
about, and feel better about themselves. Hester was the topic of sermons, and the
emotional punching bag of a town full of hypocrite puritans.  Therefore, there is no
sincerity in the hearts of any of the people in Boston.


If
anything, at some point in the novel it seemed as if Hester had become a soldiering
member of society, Scarlet letter and all, but we come to find out that Hester was as
fed up with her people towards the end as they had been angry at
her.

What are some chief thematic and stylistic features of Sir Francis Bacon's Essays?

When discussing the style and themes of Sir Francis
Bacon’s Essays, it’s important to remember that the
Essays were published in three editions in Bacon’s lifetime. Each
new edition added more themes to the list of topics treated, and each of the later
editions presented essays that tended to be longer, and more elaborate in style, than
the editions that preceded them. Nevertheless, critics have cited some common traits of
Bacon’s style and themes, and perhaps these can best be illustrated by examining a
particular essay – in this case, the essay titled “Of
Death.”


Bacon’s essays are often said to contain short,
pity, memorable phrases as well as balanced sentence structure, and certainly all of
those traits are evident in the opening words of the essay “Of
Death”:



Men
fear death, as children fear to go in the dark; and as that natural fear in children, is
increased with tales, so is the
other.



Here the phrase “men
fear death” immediately catches our attention. “Men” is balanced later by “children,”
and the phrasing that follows the semicolon is as balanced as the phrasing that precedes
it. Meanwhile, the phrases on either side of the semicolon are themselves balanced, and
this frequent use of balance in Bacon’s essays suggests the mental balance and sensible
reasoning of the author. The fact that Bacon is dealing with such a universally
interesting topic as death is also typical of his essays, which very often deal with
precisely such topics. Rather than writing about his personal experiences or
perceptions, Bacon writes about topics likely to interest most readers, and he does so
in a fairly impersonal style.


Bacon is often said to write
in a crisp, terse, clipped manner, in a style influenced by Tacitus and Seneca rather
than by the long, elaborately developed sentences of Seneca, and this tendency to
terseness can be seen in the following sentence:


readability="6">

Revenge triumphs over death; love slights it;
honor aspireth to it; grief flieth to it; fear preoccupateth it . . .
.



In his essays, especially
the later or revised ones, Bacon tends to cite classical examples to make his points and
even to quote from classical sources.  In the essay “Of Death,” for instance, he writes
as follows:


readability="15">

Augustus Caesar died in a compliment;
Livia, conjugii nostri memor, vive et vale.
Tiberius in dissimulation; as Tacitus saith of him, Jam Tiberium vires et
corpus, non dissimulatio, deserebant
. Vespasian in a jest, sitting upon the
stool; Ut puto deus fio. Galba with a sentence; Feri, si
ex re sit populi Romani
; holding forth his neck. Septimius Severus in
despatch; Adeste si quid mihi restat agendum. And the
like.



Today, many of Bacon’s
sentences, as in the passage just quoted, would be considered fragments, but they are
typical of the often lightning speed of his style and of his emphasis on matter over
manner, substance over conventionally “correct” grammar. Bacon rarely develops the full
implications of many of his ideas. Instead, he often mentions an idea quickly and then
swiftly moves on to the next, thereby encouraging readers to make connections and to
think for themselves. Certainly that is one of the effects of the essay “Of
Death.”

What is the difference between suffragist and suffragette movements?

Both terms are very similar in their meaning.  They both
refer to women seeking the right to vote against a patriarchal establishment.  The
differences between the term might relate to how those who fought for this right were
viewed by the social and political orders.  The term "suffragette" was coined by British
media to describe in a derogatory manner those women who were staunch advocates of
social change.  Similar to the term "Queer" in United States history and lecixon,
something that was used to demonize and separate ended up becoming appropriated as a
"badge" or a nameplate that indicated change.  "Suffragette" became appropriated by
women fighting for the right to vote and was transformed into "suffragist," a term that
was accepted in America when American women sought the same rights in their nation.  The
suffix of "-ette" was seen as the derogatory element, seeking to use language to keep
women in a position of social subservience.  Yet, the appropriation of language to
assert power can be seen and through it, women's political rights in both England and
the United States.
