1st question the height (h) in feet of a projectile launched vertically upward from the top of a 280-foot tall bridge is given by h= 280 + 48t - 16t^2 where t is time in seconds. when does the projectile reach a maximum height and how long will it take the projectile to strike the ground? second question chris want to make an enclosed rectangular area for a mulch pile. she wants to make the enclosure in such a way as to use a corner of her back yard. she also wants it to be twice as long as it is wide. since the yard is already fenced, she simply needs to construct two sides of the mulch pile enclosure. she has only 15 feet of material available. find the dimensions of the enclosure that will produce the maximum area.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
