a batter hits a fly ball. a scout in the stands makes the following observations
time
(seconds)x
75
1.5

2.75
3.25
4.75
height
(feet)y
77
133
160

169

use a graphing calculator to perform the regression for the best-fit equation.

i came up with:

y= ax ²+bx+c
y=(-15.90)x^2+110.49 x+3.01

a= -15.90 b = 110.48; c= 3.01

i need with these:

determine the initial velocity of the baseball and the height of the ball when hit. round to
the nearest hundredth.

calculate how many seconds an outfielder has to position himself for the catch if he
intends to catch the ball 6 feet above the ground. show your work and round to the
nearest hundredth
