Question

Can someone pleaseeee help me ​

Answer 1

Explanation:

Given that ,the height ,h in feet of a baseball after being stuck by a bat can be approximated by h(t) =
`-16t^2+100t +5`

a)

Now h(t) for t=3

h(3) =
`-(16* 3^2)+ (100* 3)+5` = 161 feet

and h(t) for t= 5

h(5)
`=-(16* 5^2)+ (100* 5)+5`=105 feet

b)

Since the height of baseball decreases with respect of time . Its mean that the baseball come down .
