****PLEASE explain your answer****

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.

Answer:

  (b)  f(x) = (-x)^(1/2)

Step-by-step explanation:

The square root is only defined for argument values that are non-negative. Hence the domain of ...

  f(x) = (-x)^(1/2)

is all values of x less than or equal to zero. This is not "all values of x."

Answer:

Option B

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of the line passing through (-5, -2) and (3, -1) will be,

m = [tex]\frac{-1+2}{3+5}[/tex]

m = [tex]\frac{1}{8}[/tex]

Equation of the line passing through (h, k) and slope 'm' is given by,

y - k = m(x - h)

Therefore, equation of the line passing through (3, -1) and slope = [tex]\frac{1}{8}[/tex] will be,

[tex]y+1=\frac{1}{8}(x-3)[/tex]

[tex]y=\frac{1}{8}x-\frac{3}{8}-1[/tex]

[tex]y=\frac{1}{8}x-\frac{11}{8}[/tex]

Option B will be the answer.

Step-by-step explanation:

A quadratic function is given to us . And we need to fill out the table by using the function . The given function is ,

[tex]\rm\implies y = x^2+x - 6 [/tex]

Here we need to substitute the different values of x , to get the different values of y.

Put x = -3 :-

[tex]\rm\implies y = 3^2-3-6\\ [/tex]

[tex]\rm\implies y = 9 - 3 - 6 \\[/tex]

[tex]\rm\implies y = 0 [/tex]

Put x = -2 :-

[tex]\rm\implies y = 2^2-2-6\\ [/tex]

[tex]\rm\implies y = 4 -2-6\\[/tex]

[tex]\rm\implies y = -4 [/tex]

Put x = -1 :-

[tex]\rm\implies y = -1^2-1-6\\[/tex]

[tex]\rm\implies y = 1 -1-6 \\[/tex]

[tex]\rm\implies y = -6 [/tex]

Put x = 1 :-

[tex]\rm\implies y = 1^2+1-6\\ [/tex]

[tex]\rm\implies y = 2 -6[/tex]

[tex]\rm\implies y = -4[/tex]

Put x = 2 :-

[tex]\rm\implies y = 2^2+2-6\\ [/tex]

[tex]\rm\implies y = 4 +2-6\\ [/tex]

[tex]\rm\implies y = 2[/tex]

Put x = 3 :-

[tex]\rm\implies y = 3^2+3-6\\ [/tex]

[tex]\rm\implies y = 9 +3-6\\ [/tex]

[tex]\rm\implies y = 6 [/tex]

Answer:

Speed of canoiest is 10 miles/hour.

Speed of current is 2 miles/hour.

Step-by-step explanation:

Let the speed of canoiest is v and the speed of current is u.

distance = speed x time

24 = (v + u ) x 2

v + u = 12 ..... (1)

Now

24 = (v- u) x 3

v - u = 8 .... (2)

By solving (1) and (2)

2 v = 20

v = 10 miles/hour

u = 2 miles/hour

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.

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

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 :)

Answer:

The probability that they purchased a green or a gray sweater is [tex]\frac{12}{31}[/tex]

Step-by-step explanation:

Probability is the greater or lesser possibility of a certain event occurring. In other words, probability establishes a relationship between the number of favorable events and the total number of possible events. Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.

[tex]P(A)=\frac{number of favorable cases}{number of possible cases}[/tex]

The addition rule is used when you want to know the probability that 2 or more events will occur. The addition rule or addition rule states that if we have an event A and an event B, the probability of event A or event B occurring is calculated as follows:

P(A∪B)= P(A) + P(B) - P(A∩B)

Where:

P (A): probability of event A occurring.

P (B): probability that event B occurs.

P (A⋃B): probability that event A or event B occurs.

P (A⋂B): probability of event A and event B occurring at the same time.

Mutually exclusive events are things that cannot happen at the same time. Then P (A⋂B) = 0. So, P(A∪B)= P(A) + P(B)

In this case, being:

You know:

So:

Then:

P(A∪B)= P(A) + P(B)

P(A∪B)= [tex]\frac{8}{31}+ \frac{4}{31}[/tex]

P(A∪B)= [tex]\frac{12}{31}[/tex]

The probability that they purchased a green or a gray sweater is [tex]\frac{12}{31}[/tex]

Answer:

n = 9

Step-by-step explanation:

24 = -3 + 3n

24 + 3 = 3n

27 = 3n

9 = n

Answer: n = 9

Step-by-step explanation:

24 = -3+ 3n  - so + 3 on both sides - you get

27 = 3n - then divide both sides by 3 - which is

9 = n

n = 9

Answer:

22.5

Step-by-step explanation:

 percent is any number over 100, so 25% is 25 over 100, this means that 25% can be written as:

25100

Now, any number in fractional form (a number over a number) is the same as division so 25% can also be written as a decimal, we just move the decimal point 2 places to the right of 25, like this:

25100=0.25

Now we have two ways that we can solve this problem! I'll start with the fractional method of solving.

Answer:

x = 0 or x = 3

Step-by-step explanation:

-3x(x-3)(x^2+16)=0

3x = 0

x-3 = 0

x^2+16 =0 (not possible with real numbers)

x = 0, x= 3

Hence,

x = 0 or x =3

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:  Choice A.   [tex]-x^2+2x+8[/tex]

Work Shown:

[tex](f - g)(x) = f(x) - g(x)\\\\(f - g)(x) = (2x+1) - (x^2-7)\\\\(f - g)(x) = 2x+1 - x^2+7\\\\(f - g)(x) = -x^2+2x+(1+7)\\\\(f - g)(x) = -x^2+2x+8\\\\[/tex]

which shows the answer is choice A.

Side note: be sure to distribute the negative to every term inside the second set of parenthesis. So you wouldn't say -(x^2-7) = -x^2-7. If you did this error, then you'd get to the wrong answer choice C.
