The height ,h, in feet of a baseball that is popped up into the air is a quadratic function of the time, t, in seconds, since it was hit. an equation that may model this situation is h(t)=4+60t-16t^2. answers the following questions accurately, rounding to two decimals places when needed. how high is the ball when it strikes the bat?

Step-by-step explanation:

The exercise provides you the following Quadratic function:

Then, based on the information given in the exercise, you can conclude that, when the ball strikes the bat, the time in seconds is the following:

Therefore, in order to calculate the height in feet of the ball when it strikes the bat, you need to subsititute into the function and    then evaluate.

Then, you get this result:
