Aball is kicked upward with an initial velocity of 68 feet per second. the ball's height, h (in feet), from the ground is modeled by h=-16t^2+68t where t is measured in seconds. what is the practical domain in this situation?

A: 0 less than or equal to t less or equal to 4.25

Step-by-step explanation: did it in edge

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
