Bell Work: Solve using the quadratic formula. The Point Imperial is the highest point of the Grand Canyon and it is 8,800 feet tall. A professional

hiker climbed to the top of one of the rims of the Grand Canyon that is 348 feet below Point

Imperial. The hiker threw a rock upward from that rim with an initial velocity of 18 ft per second.

How many seconds will it take the rock to hit the ground? Round your answer to the nearest tenth

of a second

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
