3.) When debris is dropped from a cliff its height, h, measured in feet at various times, t, measured in seconds, is shown in the accompanying table.
Time (t): 0 1 2 3 4 5
Height : 875 843 807 741 662 450
a) State the quadratic regression equation which models the data [Round coefficients to the nearest thousandth.]
b) Using this regression equation, find the approximate height, rounded to the nearest foot, of the debris at time t = 7 seconds.
c) Predict at what time, to the nearest tenth of a second, the debris will hit the ground.
