2. An apple falling from a tree is h feet above the ground t seconds after it begins to fall, where h=64-16t^2
After how many seconds will the apple hit the ground?

step-by-step explanation:

i think you should think about the question and not look online.

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

answer: you need to organize this better it does not make sense.
