## anonymous one year ago 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, f(t), in feet, at different times (t) in seconds: f(t) = -16t2 + 48t + 100 The average rate of change of f(x) from x = 3 seconds to x = 5 seconds is _____feet per second.

$\frac{ ((-16(5)^{2}+48(5)+100)-(-16(3)^{2}+48(3)+100)) }{ 5-3 }$

2. LynFran

$\frac{ ((-16(25)+340)-(-16(9)+244)) }{ 2 }$
