A ball is thrown into the air with an upward velocity of 36 ft/s. Its height h in feet after t seconds is given by the function mc0161.jpg. In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. What is the ball’s maximum height?
2.25 s; 10 ft
1.13 s; 32.5 ft
1.13 s; 30.25 ft
1.13 s; 70.75 ft

Best ResponseYou've already chosen the best response.0wouldn't it be A? (2x + 7)(x – 4) = 0 (2x + 4)(x + 7) = 0 (2x – 7)(x + 4) = 0 (2x – 4)(x + 7) = 0

Best ResponseYou've already chosen the best response.0I have one similar to my very fist question.. A ball is thrown into the air with an upward velocity of 48 ft/s. Its height h in feet after t seconds is given by the function h=16t^2+48t+6 In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. What is the ball’s maximum height?
