Answer:
52
Step-by-step explanation:
Given the the equation h(t) =- where t is the time in second
So to find the ball's maximum height we can apply the vertex formula:
t=
to find the "x" value of the vertex, then plug that value into the original equation as a substitute for "x".
Standard quadratic form is:
=> a=15, b=30 in our given equation
<=> t =
When t =-1 we have h(t) = = 52
So the ball's maximum height is: 52
Hope it will find you well.
