Eileen is reading a novel for her library’s summer reading program. Which question can Eileen ask herself to best form a personal connection with the text?
A. What symbolism does this novel share with other novels I have read?
B. How do the facts in the text add to what I already know about my research topic?
C. What connections can I build between the themes in this text and other modern stories?
D. How do the struggles of the characters compare with challenges I have faced in my own life?
Answer:
Step-by-step explanation:
To begin with the answer. This is very personal, but I would choose D. I think you have to relate things to what you know. How do other people live through the same problem? Does the author believe that the best path has been chosen, or does he/she believe that the central character is doomed to failure? And how do these comments relate to me. You are going to get the most out of any novel when you can relate to the central character or any of the characters for that matter.
I'm not concerned with C. You can read trash and what they say is likely consistent but that only means that trash is pandering to a clientele that does not want to think much. Whatever spin you put on C, agreement is not a terrific thing. It does not make you think.
I suppose B is important if you are reading non fiction. I'm not answering it that way.
A: not the answer. This is a very remote connection. Most of the time symbolism is not the main attraction of any novel nor especially of any non fiction writing. Moby D*ick is not a great novel because of its symbolism of which there is a huge amount. It is a great novel because the conflict is between man and nature and although that is symbolic, it is not as important as the character study of Ahab (who is himself a symbol). Nor or Ishmael for that matter. I will admit you have to have a Bible in one hand and Moby Di*ck in the other, but it is not critical. The theme is.

Given a rhombus has a side length of 15 and one diagonal has a length of 2x. Find the length of the second diagonal in terms of x. Show all work and leave your answer in radical form.
9514 1404 393
Answer:
2√(225 -x²)
Step-by-step explanation:
Let 2y be the length of the second diagonal. The half-diagonals and the side of the rhombus form a right triangle. The Pythagorean theorem tells us the relationship between sides and hypotenuse is ...
x² +y² = 15²
y² = 225 -x²
2y = 2√(225 -x²2) . . . . the length of the second diagonal
Find a solution to the initial value problem,
y″+12x=0, y(0)=2,y′(0)=−1.
Answer:
y = -2*x^3 - x + 2
Step-by-step explanation:
We want to solve the differential equation:
y'' + 12*x = 0
such that:
y(0) = 2
y'(0) = -1
We can rewrite our equation to:
y'' = -12x
if we integrate at both sides, we get:
[tex]\int {y''} \, dx = y'= \int {-12x} \, dx[/tex]
Solving that integral we can find the value of y', so we will get:
y' = -12* (1/2)*x^2 + C = -6*x^2 + C
where C is the constant of integration.
Evaluating y' in x = 0 we get:
y'(0) = -6*0^2 + C = C
and for the initial value problem, we know that:
y'(0) = -1
then:
y'(0) = -1 = C
C = -1
So we have the equation:
y' = -6*x^2 - 1
Now we can integrate again, to get:
y = -6*(1/3)*x^3 - 1*x + K
y = -2*x^3 - x + K
Where K is the constant of integration.
Evaluating or function in x = 0 we get:
y(0) = -2*0^3 - 0 + K
y(0) = K
And by the initial value, we know that: y(0) = 2
Then:
y(0) = 2 = K
K = 2
The function is:
y = -2*x^3 - x + 2

Find the volume of the figure. Round to the nearest tenth if necessary.
Answer:
Volume = 204 m³
Step-by-step explanation:
The figure is a triangular prism
Volume of the triangular prism = ½ × a × c × h
Where,
a = 8 m
c = 5.1 m
h = 10 m
Plug in the known values and solve
Volume = ½ × 8 × 5.1 × 10
Volume = 4 × 5.1 × 10
Volume = 204 m³
Anyone good with calculus? Please help.
First take a time derivative of a function describing motion,
[tex]\frac{d}{dt}h(t)=\frac{d}{dt}-4.9t^2+19.6t-14.6=-9.8t+19.6[/tex].
Finding the maxima of the function is obtained by determining where the critical points are. You can find the critical points by equating the derivative with 0 and solving for t,
[tex]\frac{d}{dt}h(t)=0[/tex]
[tex]-9.8t+19.6=0\implies t=\frac{19.6}{9.8}=\boxed{2}[/tex].
So at 2 seconds the ball peaks in height.
To find out the height feed 2 to the function h.
[tex]h(2)=-4.9\cdot2^2+19.6\cdot2-14.6=\boxed{5}[/tex].
So at 2 seconds the ball reaches maximum height of 5 meters.
Hope this helps :)

Which of the following would be an example of the Coase Theorem? A. The county commission agrees to a town meeting to hear concerns from citizens about setting off fireworks after 10 p.m. B. The county commission approves a steep fine to be placed on anyone setting off fireworks after 10 p.m. C. The homeowners association provides a fireworks show that ends at 10 p.m. D. The homeowners association agrees to report anyone setting off fireworks after 10 p.m. to the local authorities.
Answer:
The correct answer is C.
Step-by-step explanation:
Coase Theorem says that any externality can be dismantled no matter who is ultimately compensated. The theorem mainly concerns compensation for pollution of foreign property, and states that, provided certain conditions are met, negotiation can lead to Pareto's optimal outcome.
Ronald Coase came up with the idea when looking for a way to allocate broadcast frequencies as efficiently as possible to individual radio stations. Competing radio stations could not agree on which radio frequency to choose, and if more than one of them was broadcasting on the same frequency, there was mutual interference. Coase noted that, despite the lack of state regulation to ensure a fair allocation of radio frequencies, the market is able to deal with this problem as follows: Radio stations that have sought to increase their economic profits by broadcast on an exclusive frequency, they were willing to pay their competitors to switch to another radio frequency without interrupting their transmission.

Step-by-step explanation:
Water is leaking out of an inverted conical tank at a rate of13400cubic centimeters per min at the same time that water is being pumped into the tank at a constant rate. The tank has height8meters and the diameter at the top is6meters. If the water level is rising at a rate of24centimeters per minute when the height of the water is5meters, find the rate at which water is being pumped into the tank in cubic centimeters per minute.
9514 1404 393
Answer:
2,664,118.8 cm³/min
Step-by-step explanation:
The diameter at the water level of 5 m is (5/8)(6 m) = 3.75 m, so the area of the water surface is ...
A = (π/4)d² = (π/4)(3.75 m)² ≈ 11.044662 m²
When rising at the rate of 24 cm/min, the volume is increasing at the rate ...
(110,446.62 cm²)(24 cm/min = 2,650718.8 cm³/min
The input volume must be sufficient to accommodate this increase as well as the leakage. Then the input volume is ...
2,650718.8 cm³/min + 13,400 cm³/min = 2,664,118.8 cm³/min
A telephone pole has a wire attached to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor point is 49 feet less than the height of the pole. If the wire is to be 14 feet longer than the height of the pole, what is the height of the pole?
9514 1404 393
Answer:
105 ft
Step-by-step explanation:
Let x represent the height of the pole. Then (x -49) is the distance from the pole to the anchor point, and (x+14) is the length of the wire from the top of the pole to the anchor point.
The Pythagorean theorem gives us the relation ...
(x +14)² = x² +(x -49)²
x² +28x +196 = x² +x² -98x +2401 . . . . eliminate parentheses
x² -126x +2205 = 0 . . . . . . . . put in standard form
x² -126x +3969 -1764 = 0 . . . . "complete the square)
(x -63) = ±√1764 . . . . . . add 1764, take the square root
x = 63 +42 = 105 . . . . . . highest value root. The pole must be higher than 49 feet
The height of the pole is 105 feet.

Answer: [tex]y^\frac{1}{8}[/tex]
Step-by-step explanation:
Ok so when taking roots the number in the little corner at the left of the radical sign (if there is one) is the root you take. It could be the 4th root, 6th root, or the x root. You don't have to use the radical sign though, you can use an exponent to write it. All you have to do is take the reciprocal of the number to find what to write for the exponent. So for those examples it would be [tex]\frac{1}{4}, \frac{1}{6} ,\frac{1}{x}[/tex]. The number in the top left of the radical sign is 8 so the answer would be [tex]y^\frac{1}{8}[/tex]

What is the effect on the graph of f (2)
g(x) = 1 +112
A. The graph of f(x) is shifted 11 units to the left.
B. The graph of f(x) is shifted 11 units to the right.
C. The graph of f(x) is shifted 11 units up.
D. The graph of f(x) is shifted 11 units down.
Answer:
C. The graph of f(x) is shifted 11 units up.
Step-by-step explanation:
Given
[tex]g(x) = f(x) + 11[/tex]
Required
Interpret g(x)
When a function is shifted up in b units, the rule is:
[tex](x,y) \to (x,y+b)[/tex]
Replace b with 11
[tex](x,y) \to (x,y+11)[/tex]
Replace y with f(x)
[tex](x,f(x)) \to (x,f(x)+11)[/tex]
So, we have:
[tex]g(x) = f(x) + 11[/tex]
Hence; f(x) is shifted 11 units up.
