The curve y : Vac 7 1 passes through the point P(26, 5). Since Q (as, V $ 7 1) is also a point on the curve, we can find the slope of the secant line PQ for various values of :0. The slope of the secant line passing through the points P(26, 5) and Q (1:, V5: 1) is given by Part a) If Q is the point (3:, V1: 1) , use your calculator to find the slope of the secant line PQ for the given values of :3. Round to five decimal places. At :3 : 25.5, mm: At :3 = 25.9, msec: At m = 25.99, msec: At It : 25.999, mm: At :1: : 26.5, msec: At :8 : 26.1, mm: At :8 = 26.01, mm: At m = 26.001, msec: Part b) Use the results of Part (a) to estimate the slope of the tangent line to the curve at P. If necessary, round to five decimal places
