A ball travels on a parabolic path in which the height (in feet) is given by the expression $-25t^2+75t+24$, where $t$ is the ti
evablogger [386]

Answer:

The height of the ball is at it's maximum 1.5 units of time after launch.

Step-by-step explanation:

Suppose we have a quadratic function in the following format:

h(t) = at^{2} + bt + c

If t is negative, the maximu value of h(t) will happen at the point

t_{MAX} = -\frac{b}{2a}

In this question:

h(t) = -25t^{2} + 75t + 24

So

a = -25, b = 75, c = 24

Then

t_{MAX} = -\frac{b}{2a} = -\frac{75}{2*(-25)} = 1.5

The height of the ball is at it's maximum 1.5 units of time after launch.
