5. After t seconds, a ball tossed in the air from the ground level reaches a height
of h feet given by the function h(t) = 144t – 16t^2. PART A: What is the height of

Sagot :

Answer:

a = 288 feet, b = 9 seconds

Step-by-step explanation:

t = 3, solve for h(t)

h(3) = 144(3)-16(3)^2

=432-144

=288

H(t) = 0, solve for t

0=144(t)-16(t)^2

t = 0, t =9
