A ball is kicked straight up into the air. The height of the ball in feet is given by the expression -16t2+ 12t+ 4, where t is t
ime in seconds. Factor the expression. Then find the height of the ball after 1 second.
1 answer:
Answer:
0 feet.
Step-by-step explanation:
h = -16t^2 + 12t + 4
h = -4(4t^2 - 3t - 1)
= -4(4t + 1)(t - 1)
After 1 second height = -4 * 1 * 0 = 0 feet.
