Aprojectile is thrown upward so that its distance, in feet, above the ground after t seconds is h(t) = -15t2 + 510t. what is its maximum height?

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  .

No it would not. logically thinking this wouldn’t because even though your record is cleaned you are still part of system. this is from a legal view not from what even book. also alex is that you like ims alex in history and math with me in 8th aka last year. if not then oof sorry.
