Find the area of the semicircle 16 meters

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
