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
the ball after 3 seconds? PART B: After how many seconds will the ball hit the
ground before rebound? -

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

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
