4. The height h in feet of a projectile launched vertically upward from the top of a 112-foot tall tower when time (measured in seconds)t = 0 is given by h = -16t2 + 96t + 112.
a) How long will it take the projectile to strike the ground?
b) What is the maximum height that the projectile reaches?
5. The height in feet of a bottle rocket is given by h = -16t2 + 192t, where t is the time in seconds.
a)How long will it take for the rocket to return to the ground?
b)What is the height after 2 seconds?
c)What is the maximum height?
6. While playing catch with his grandson yesterday Tim throws a ball as hard as possible into the air. The height hin feet of the ball is given by h = -16t2 + 64t + 6, where t is in seconds.
a) How long will it take until the ball reaches the grandson’s glove if he catches it at a height of 4 feet?
b)What is the maximum height of the ball?
Solve by factoring, taking the square roots, or, if necessary, by using the graphing calculator. Give exact radical answers unless using the graphing calculator, then round to the nearest hundredth.
7. x2 – 5x = 08. x2 + 6x – 72 = 09. (x + 4)2 = 25
10. x2 – 3x – 8 = 011. 7x2 + 27x – 4 = 012. x2 + 6x + 9 = 0
13. x2 – 20 = 014. 5x2 + 13x – 2 = 0
Factor the following but do not solve.
