A ball is thrown upward with an initial velocity of 64 ​ft/sec from a height 720 ft. Its height​ s, in​ feet, after t seconds is given by s=−16t2+64t+720. After how long will the ball reach the​ ground?

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

What is the solution to the equation in the & show work i’m very
