Answer:

50 cm^2

Step-by-step explanation:

area of rectangle = base * height

5 * 7 = 35

area of triangle = base * height / 2

5 * 4 = 20/2 = 10

5 * 2 = 10/2 = 5

add them all up

35 + 5 + 10 = 50 cm^2

If f(x) = -7x + 1 and g(x) = Square root of x-5,<br> what is (fºg)(41)?

Ghella [55]

This is similar to the other question you posted. Follow the same steps as before.

First find g(41).

g(41) = sqrt{x - 5}

g(41) = sqrt{41 - 5}

g(41) = sqrt{36}

g(41) = 6

We now find f(6).

f(6) = -7(6) + 1

f(6) = -42 + 1

f(6) = -41

Answer:

(fºg)(41) = -41
