A baseball is hit, and rises to a height above the ground, f(t), in feet, at time t, in seconds, can be estimated by the formula: f(t)=-10t^(2)+40t+8

Step-by-step explanation:

The given function is

To find the maximum height reached by the ball, we need to find the vertex of the parabolla represented by the given quadratic equation.

Remember that a vertex has coordinates (h,k), where and .

According to the given function, we have

and

So, the vertex has coordinates of (2,48), which means the maximum height reached by the baseball is 48 feet.
