A system of equations has at least one point in common in the solution (unless it is a special case)
A system of inequalities has regions of common solutions. (always an infinite number of solutions)
The graph shows the height h, in feet, of s football at time t, in seconds, from the moment it was kicked at ground level.
We are supposed to find the average rate of change in height from t=1.5 seconds to t=1.75 seconds.
Average rate of change in height=
As we can see from the the change in distance for the time interval 1.5 second to 1.75 second=
and time=
Average rate of change in height=
=20ft/sec
Hence Required Rate of change is -20 ft/sec, because its falling(In the direction of negative y-aixs)
