If f(x) = -4x + 2 and g(x) = sq root X – 8,<br>what is (fºg)(12)?

Anettt [7]

Answer:

$(fog)(12)=-6$

Step-by-step explanation:

Recall that the notation: $(fog)(12)$ is the same as: $f(g(12))$ which means the value of the function f when you give it as input the value obtained by evaluating g(12).

Therefore, we need to start finding what g(12) is using the definition :

$g(x)=\sqrt{x-8}$ and evaluating it as x = 12.

$g(x)=\sqrt{x-8}\\g(12)=\sqrt{12-8}\\g(12)=\sqrt{4}\\g(12)=2$

So now we use this answer "2" as input for f(x):

$f(x)=-4x+2\\f(2)=-4(2)+2\\f(2)=-8+2\\f(2)=-6$

Therefore, $(fog)(12)=-6$

The length of a rectangle is four times its width. if the perimeter of the rectangle is 80yd, find its length and width.

Vedmedyk [2.9K]

The length is 8. the width is 32.

32(2) = 64

8(2) = 16

64+16 = 80

So the length would be 8 and the width would be 32 since it's 4 times the length.

Hope this helped!

Latoya's annual salary is $26,000. A total of $7352.24 will be deducted for taxes and health insurance. She will receive her pay

Anna71 [15]

Step-by-step explanation:

Lets translate this word problem into math.

"Latoya's annual salary is $26,000" = We start with the number 26,000

"A total of $7352.24 will be deducted for taxes and health insurance" = It's the number we started with "deducted" (minus) 7352.24

"She will receive her paycheck monthly in 12 equal installments" = Our number will be divided by 12

"How much will she get paid with each paycheck?" = "Find answer pls thx"

To put it all together...
