44. Lauren throws a ball with an initial velocity of 40 feet per second
Lauren throws a ball with an initial velocity of 40 feet per second. The equation for the height of the ball is h = -16t2 + 40t + 5, where h represents the height in feet and t represents the time in seconds. When will the ball hit the ground? (SOLVE USING QUADRATIC FORMULA!!)

45. It will hit the ground in approximately 2.62 seconds.

46. Craig Hoffheimer wants to build a swimming pool surrounded by a sidewalk of uniform width. He wants the dimensions of the pool and sidewalk to be 16 meters by 20 meters. The pool has an area of 192 square meters. How wide should the sidewalk be?

47. The sidewalk should be 2m all the way around.

48. A ball is thrown into the air vertically
with a velocity of 112 feet per second.
The ball was released 6 feet above the
ground. The height above the ground
t seconds after release is modeled by
H(t) = -16t t + 6
When will the ball reach 130 ft?
Will the ball ever reach 250 feet?
c. In how many seconds after its release
will the ball hit the ground?

49. About 1.4s and 5.6s
No, it only goes to 202
In about 7 seconds
