My bad i can u but i can’t type it all here

You're asking in the ap section, so i'll give the ap calculus-style answer. alternatively, you can find the vertex of the parabola and use the "y"-coordinate as the answer.

the maximum height can occur at a critical number, that is, a number  such that  .

the derivative of  can be calculated as follows:



find a value of  that is a zero of the derivative:


this is parabola that is opening downward; we can assume there is a maximum at  .

to find that maximum, calculate  .

The answer is:   [a]:   " affidavit" .

It took me a while to figure out this complex expression but i believe the answer you’re looking for is

but i am not sure because i am not at that level of math yet.
