The quadratic function h(t) = -16.1t^2 + 150 models a balls height, in feet, over time, in seconds, after its dropped from a 15 story building. from what height in feet was the ball dropped?

If eh = hg and hg=16, find the diameter of k

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.
