The height of a soccer ball that is kicked from the ground can be approximated by the function: y = -16x² + 48x

where y is the height of the soccer ball in feet x seconds after it is kicked.

Find the time, in seconds, it takes from the moment the soccer ball is kicked until it returns to the ground. ​

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
