Some fireworks displays can reach heights of over 300 meters. The height of a firework shell, in meters, 1 seconds after launch can be modeled by the function f (t) = -4.912 + 80t. How many seconds does it take for the shell to first reach a height of 300 meters round to the
nearest tenth of a second.

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2

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:
