10. A ball is thrown from a 96 foot platform. The height of the ball in feet is 10 points modeled by H(t) = -16t? + 80t + 96, where t is the time in seconds after
the ball is thrown. When will the ball hit the ground? Remember to include
units in your answer.

step-by-step explanation:

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:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
