15. The local recreation center has asked you to design a machine that launches a hopper full of basketballs at a hoop so the team can practice rebounding drills. The machine needs to adjust to multiple hoop heights for all age levels. The equation that represents the height of the basketball as a function of time (t) in seconds is: h=-16t2+32t+3 How many seconds does it take for the ball to pass through a 8 foot hoop coming down? Round to the nearest hundredth. ball passes through the hoop at t= seconds
