HW1: Average and Instantaneous Velocity OPEN Turned in automatically when due. ITEMS INFO 1. Practice similar Next > The point P(9, 7) lies on the curve y = vi + 4. Let Q be the point (x, Vi + 4). a. Find the slope of the secant line PQ (correct to six decimal places) for the for the following values of a. If x = 9.1, the slope of PQ is: 0.166206 If a = 9.01, the slope of PQ is: 0.16662 If x = 8.9, the slope of PQ is: 0.167132 If a = 8.99, the slope of PQ is: 0.166713 b. Based on the above results, estimate the slope of the tangent line to the curve at P(9, 7). Answer: 0.16 Submit answer Answers (in progress)
