Answer:
6 feet
Step-by-step explanation:
A soccer ball is kicked from the ground in an arc defined by the function,
[tex]h(x) = -2x^2 + 8x[/tex]
h(x) is the height of the ball and time is t.
we need to find out the height when t= 3 seconds
Plug in 3 for t
[tex]h(x) = -2x^2 + 8x[/tex]
[tex]h(3) = -2(3)^2 + 8(3)[/tex]
[tex]h(3) =-18+24=6[/tex]
The height of the ball after 3 seconds is 6 feet.
