8. A baseball pitcher throws a baseball with an initial velocity of 135 feet per second at an angle of 21 to the horizontal. The ball leaves the pitcher's hand at a height of 5 feet. The trajectory of the ball can be described by the set of parametric equations :1: = 126.0% 3; = 16t2 + 48.38: + 5 [a] [2 points) For how long is the ball in the air after being thrown? You can round to the nearest tenth of a second. {b} [2 points) How many feet away from the pitcher will the ball land? You can round to the nearest foot. (c) Optional Extra Credit! (1 point) Hon;r did I calculate the numbers 126.03 and 48.38 in the set of parametric equations above? 1.
