Question

In a soccer game, Sally kicks the ball to a teammate who is on the other side of the field. The ball's height h (in feet above the ground), t seconds after Sally kicked it, is modeled by: h ( t ) = − 2 t ^2 + 10 t What is the height of the ball at the time it is kicked?

Answer 1

Answer: 0

Step-by-step explanation:

h ( t ) = − 2 t ^2 + 10 t

h = height of ball above the ground

t = time, seconds after ball was kicked

Height of ball at the time it is kicked?

At the time ball is kicked, time (t) = 0

Therefore,

h ( t ) = − 2 t ^2 + 10 t

h( 0) = - 2(0)^2 + 10(0)

h = 0 + 0

h = 0

The ball was the on the grounf at the time it was kicked.
