Math what is the maximum height of the ball? when is the ball at this max height? when will the ball hit the ground? what is the domain?

See attached picture of what the graph looks like:

what is the maximum height of the ball?  115.39 feet

when is the ball at this max height?  2.66 seconds

when will the ball hit the ground?  5.34 seconds

what is the domain? The domain is the time the cannon ball is in the aire which is all values from o seconds to 5.34 seconds:  0 < x < 5.34

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
