3) use a graph of the function to estimate the slope of the tangent line at P. (This slope represents the rate at which the water is flowing from the tank after 15 minutes)

Step 1

Draw a graph by plotting the points (5, 694), (10, 444), (15, 250), (20, 111), (25, 28) and (30, 0). Draw the slope of tangent line at P.

Step 2

Then we ha...
