Your new phew is standing on his deck which is 4 feet off the ground. He tosses his toy up into the air. The equation h(t) = -2t

Tpy6a [65]

Answer:

The height of the toy is 9 feet after 1 second

Step-by-step explanation:

we have

$h(t)=-2t^2+7t+4$

where

h(t) is the toys height from the ground

t is the time in seconds

For t=1 sec

substitute the value of t in the quadratic equation and solve for h(t)

$h(1)=-2(1)^2+7(1)+4$

$h(1)=9\ ft$
