During a baseball game, a player’s ball hit into the outfield is modeled by the equation h = –16t2 + 65t. a bird flying across the field follows the path modeled by the equation h = 8t + 20. let t be the time since the ball is hit and h be the height. what do the intersection points of the equations represent? a. the height when the ball and the bird are the same distance across the field b. the height when the ball is hit and the bird starts flying across the field c. the time when the height of the ball and the bird are the same d. the time when the ball and the bird hit the ground

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .
