after t seconds is given by the following equation:
h(t)=-4.9t^2+25t
1. the height of the ball t seconds after being thrown
2. the height of the ball between 1 and 2 seconds
3. the height of the ball between 1.5 and 2.5 seconds
4. the change per second in the height of the ball between a and b seconds

                    ANSWERS


1. the height of the ball t seconds after being thrown:  h(t).


2. the height of the ball between 1 and 2 seconds:       h(1) <= h <= h(2).


3. the height of the ball between 1.5 and 2.5 seconds:  h(1.5) <= h <= h(2.5).


4. the change per second in the height of the ball between a and b seconds:  %28h%28b%29+-+h%28a%29%29%2F%28b-a%29.
