Answer:

\boxed{\sf \ C \ is \ the \ correct \ answer \ ! \ }

Step-by-step explanation:

fog(x)=f(g(x))

so it comes

f(g(x))=f(x+1)=4(x+1)^2

<u>so C is the correct answer</u>

Answer:

Option B

Step-by-step explanation:

f(x) = 4x^2\\g(x) = x+1

Multiplying both will give us:

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

=> (fg)(x) = 4x^3+4x^2

It takes 26 pounds of seed to completely plant a 3-acre field. How many pounds of seed are needed per acre?
satela [25.4K]

Answer:

3.25 pounds per acre

Step-by-step explanation:

We want to find how much pounds of seed is need per acre. In division, with a numerator and denominator, this works perfectly, with how much we need (of seed) per acre translating into \frac{26 pounds}{3 acres} , with the line representing the per. We can plug this into a calculator to get 3.25 pounds per acre, or \frac{3.25 pounds}{1 acre}

PLEASE HELP!! WILL MARK BRAINLIEST AND THANK YOU!!
tangare [24]

Answer:

Option D (-4,7)

Step-by-step explanation:

we have

Square TUVW with vertices T(-6,1), U(-1,0), V(-2,-5), and W(-7,-4

<u><em>The question is</em></u>

Find out the coordinates of U'

Part a) Reflection: in the y-axis

we know that

The rule of the reflection of a point across the y-axis is

(x,y) -----> (-x,y)

so

U(-1,0) -----> U'(1,0)

Part b) Translation (x,y) —> (x-5,y+7)

That means ---> the translation is 5 units at left and 7 units up

so

U'(1,0) -----> U''(1-5,0+7)

U'(1,0) -----> U''(-4,7)

therefore

Option D (-4,7)

Robert Russell earns 3% commission on the sale of a $512,800 home. What is his<br> commission?
leva [86]

Answer:

The commission is  \$15,384

Step-by-step explanation:

we know that

3\%=3/100=0.03 ----> percentage of the commission in decimal form

To find out how much is the commission, multiply the amount of the sale of the home by the percentage of the commission in decimal form

so

512,800(0.03)=\$15,384
