how would you go ahead and fill out this problem. I'm getting confused along the way. Thanks! An explanation would be awesome as well! Thanks in advance!
A tank holds 4000 gallons of water, which drains from the bottom of the tank in half an hour. The values in the table show the volume V of water remaining in the tank (in gallons) after t minutes. If P is the point (15, 1020) on the graph of V, find the slopes of the secant lines PQ when Q is the point on the graph with the following values. Slopes of secant lines passing through P(15, 1020) and Q(t, 1/(0) can be calculated using We begin by calculating the slope when t = 5. Estimate the slope of the tangent line at P(15, 1020) by averaging the slopes of two adjacent secant lines. Looking at the table, the t-values adjacent to t = 15 areExplanation / Answer
1)
(5, 2740)=> slope = -89.66 degrees
(10,1800)=> slope = -89.63 degrees
(20,412) => slope = -89.52 degrees
(25, 104)=> slope = -89.49 degrees
(30,0) => slope = -89.15 degrees
tangent = -89.575 degrees
