A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, ft, in feet, at different times t in seconds:
f(t) = 16t2 + 32t + 90
The average rate of change of f(t) from t = 4 seconds to t = 6 seconds is _____ feet per second.

Best ResponseYou've already chosen the best response.1we'll be using the formula for average rate of change [f(6)f(4)] / (64) so, first start by finding f(6)f(4) = ?

Best ResponseYou've already chosen the best response.1not quite f(t) = 16t^2 + 32t + 90 f(6) = ?

Best ResponseYou've already chosen the best response.1using the same method you just did, just set t = 4 instead of 6

Best ResponseYou've already chosen the best response.1good, now plug everything back into our formula {f(6)f(4)] / (64)

Best ResponseYou've already chosen the best response.0so 294+38? @Vocaloid

Best ResponseYou've already chosen the best response.1that's part of it the numerator is f(6)  f(4) = 294+38 and the denominator is (64) so divide the numerator by the denominator
