    5. If an object is dropped from a height of 400 feet, the function h(t) = -16t2 + 400 gives the height of the object after t seconds. When will the object hit the ground? (1point) a. 25 seconds b. 10 seconds c. 5 seconds d. 2.5 seconds 6. A ball is thrown into the air with an upward velocity of 24 ft/s. Its height (h) in feet after t seconds is given by the function h = –16t2 + 24t + 5. How long does it take the ball to reach its maximum height? What is the ball’s maximum height? Round to the nearest hundredth, if necessary. (1 point) a. 1.5 s; 5 ft. b. 0.75 s; 32 ft. c. 0.75 s; 11 ft. d. 0.75 s; 14 ft. 22. A rocket is launched from atop a 68-foot cliff with an initial velocity of 155 ft/s. The height of the rocket above the ground at time t is given by h = –16t2 + 155t + 68. When will the rocket hit the ground after it is launched? Round to the nearest tenth of a second. 23. What kind of function best models the data in the table? Use differences or ratios. x y 0 -2 1 -3 2 -4 3 -5 4 -6 24. What kind of function best models the data in the table? Use differences or ratios. x y 0 1.9 1 7.6 2 30.4 3 121.6 4 486.4 25. Write an equation to model the data in the table. x y 0 2 1 -1.7 2 -5.4 3 -9.1 4 -12.8

    5. If an object is dropped from a height of 400 feet, the function h(t) = -16t2 + 400 gives the height of the object after t seconds. When will the object hit the ground? h(t) = -16t2 + 400 the height on the ground is 0 0 = -16t2 + 400 try solving for t

    wanna give it a try? -16t2 + 400 = 0 subtract 400 from both sides

    okay i will...so -16t2 + 400 - 400 and then 0 - 400?

    -16t2 + 400 - 400 = 0 - 400 so what will that be?

    no -16t2 + 400 - 400 = 0 - 400 -16t2 = - 400 now divide everything by (-16)
