Answer: The direction of the rotation is counterclockwise about the origin.

Step-by-step explanation:

          [tex](x,y)[/tex] → [tex](-y, x)[/tex]

In this case, we can observe that the coordinates of the Pre-image of the Point G are:

[tex](7 ,-5)[/tex]

And the coordinates of its Image are:

[tex](5, 7)[/tex]

Then:

[tex](x,y)[/tex] → [tex](-y, x)[/tex]

[tex](7 ,-5)[/tex] → [tex](5, 7)[/tex]

Therefore, the direction of the rotation is counterclockwise about the origin.

Answer:

C. (4,28)

Step-by-step explanation:

The substitution method requires you to input a specified number in place of a variable. In this case, the variable 'x' should be replaced by the number 4. Using the order of operations, we know that multiplication should be applied before subtraction. When we replace 'x' with 4, we get the equation 'y=8(4)-4'. Multiplying 8 and 4 gives us 32. If we subtract 4 from 32, we get 28. The answer ends up being 'y=28'.

That is the first part of our solution. What we are actually looking for is an ordered pair. We know ordered pairs are written in the form (x, y). First, we need to find the 'x'. The 'x' has been given to us from the beginning, it is 4. Next is the 'y'. This is what we needed to find using substitution. We ultimately concluded that the 'y' is equivalent to 28. Therefore our ordered pair is (4, 28), the letter choice C.

I hope this helped you and that I clearly elaborated on the answer choice.

Answer:

The expression is 5⁵-1 (=3124)

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find the zeros, set y=-4(x - 3)2 + 8 = 0.  Then -4(x - 3)^2 = -8, and:

4(x - 3)^2 = 8.  Dividing both sides by 4 yields (x - 3)^2 = 2.

Taking the square root of both sides yields x - 3 = ±2, so that

x = 3 ±2, or x = 5 and x = 1.  These are the zeros. The correct interpretatioon is A:  where the daily profit is $0.

Answer:

Interpretation: The zeros are where the daily profit is $0.00.

Zeroes are x = 1.58 and x = 4.41.

Step-by-step explanation:

Given function,

[tex]y=-4(x-3)^2+8[/tex]

For finding the zeros,

y = 0,

[tex]-4(x-3)^2+8=0[/tex]

[tex]-4(x-3)^2=-8[/tex]

[tex](x-3)^2=2[/tex]

[tex]x-3=\pm \sqrt{2}[/tex]

[tex]\implies x = 3\pm \sqrt{2}[/tex]

[tex]\implies x\approx 4.41\text{ or }x=1.58[/tex]

Hence, the zeroes of the function are x = 1.58 and x = 4.41,

∵ x represents the price of a taco and y represents daily profit,

Therefore, the zeroes are where the daily profit is $ 0.00.

Answer:

First part:

Set h(t) = 231and solve for t.

-16t²+ 152t + 9= 231

-16t² + 152t - 222= 0

Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 231 on the way up, and the higher value is the time to reach 231 again, on the way down.

Second part:

Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.

Answer:

Step-by-step explanation:"

The electrician charges an initial fee of $42", AND "The electrician charges $22 for every hour worked" is true.

The equation is y=22x+42. The formula is y=mx+b.m is the slope, or is this case, the number of dollars for every "x", which is the number of hours worked. So you have to pay $22 for every hour the electrician works.b is the y-intercept, or the amount it starts with, in this case, you have to pay a fee of $42 even when the electrician worked 0 hours. This is because $42 is the amount it starts with.On a graph, the line will start at (0,42) because that is when you start paying. And then it will increase by 22 for each hour, so the next coordinate would be (1,64).

The given function y=22x+42 represents the electrician’s charges. The electrician charges $22 for each hour worked and has a flat service fee of $42.

The given function y=22x+42 stands for the electrical work charges in terms of hours worked. Here 'y' represents the total amount charged, 'x' represents the number of hours worked, '22' is the hourly rate and '42' is likely a fixed service fee regardless of the hours worked. So the aspects that holds true for this function are: (1) The electrician charges $22 per hour of work, (2) The electrician has a fixed service fee of $42 whether or not they have worked any hours

Answer:

f(g(-1)) = -8 and g(f(1/2) = 4/19.

Step-by-step explanation:

The question specifies f(x) = x^2 + 9x and g(x) = 1/x. The question requires that there should be composite functions. This means a function in a function. Therefore, f(g(x)) means that the function g(x) is taken is an input in the function f(x). Simply replace g(x) instead of x in f(x). This gives:

f(g(x)) = (1/x)^2 + 9(1/x) = x^(-2) + 9/x.

Similar process for g(f(x)) gives:

g(f(x)) = 1/(x^2 + 9x).

Now there are two separate composite functions. Now taking inputs in the composite functions:

f(g(-1)) = (-1)^(-2) + 9/(-1) = 1 - 9 = -8.

g(f(0.5) = 1/(0.5^2 + 9(0.5)) = 1/(0.25+4.5) = 1/4.75 = 100/475 = 4/19.

Therefore f(g(-1)) = -8 and g(f(1/2) = 4/19!!!

Answer:

Henry's monthly payment is $457.5

Henry pays up for the boat at the end overall $35,960

Step-by-step explanation:

* Lets explain how to solve the problem

- Henry buys a large boat with full amount of $32,000

- He cannot pay the full amount at once

- He puts a down payment of $14,000

- He receives a loan for the rest of the payment

∵ The rest of payment = 32,000 - 14,000 = $18,000

- The loan has an interest rate of 5.5%

∴ The rate of interest = 5.5/100 = 0.055

- It is to be paid out over 4 years

∵ The amount of interest = P × r × t , where

# P is the principle amount

# r is the rate

# t is the time

∵ P = 18, 000 , r = 0.055 , t = 4

∴ The amount of interest = 18,000 × 0.055 × 4 = $3960

- The total remaining amount is the sum of the rest of payment and

 the amount of interest

∵ The rest of payment is $18,000

∵ The interest amount = $3,960

∴ The total remaining amount = 18,000 + 3,960 = $21960

- The number of monthly payments = 12 × t

∵ t = 4

∴ The number of monthly payment = 12 × 4 = 48 months

- The monthly payment = the total remaining ÷ the number of

  monthly payment

∵ The total remaining is 21960

∵ The number of monthly payment = 48

∴ The monthly payment = 21960 ÷ 48 = $457.5

* Henry's monthly payment is $457.5

- The total paying for the boat is the sum of the payment down and

  the remaining total payment

∵ The payment down is $14,000

∵ The remaining total payment is 21,960

∴ The total payment for the boat = 14,000 + 21,960 = $35,960

* Henry pays up for the boat at the end overall $35,960
