Chapter 14, Problem 39RE

Instantaneous Rate of Change The following data represent the revenue R (in dollars) received from selling x wristwatches at Wilk’s Watch Shop.

Wristwatches, x Revenue , R 0 0 25 2340 40 3600 50 4375 90 6975 130 8775 160 9600 200 10000 220 9900 250 9375

Find the average rate of change of revenue from x = 25 to x = 130 wristwatches.

Find the average rate of change of revenue from x = 25 to x = 90 wristwatches.

Find the average rate of change of revenue from x = 25 to x = 50 wristwatches.

Using a graphing utility, find the quadratic function of best fit.

Using the function found in part (d), determine the instantaneous rate of change of revenue at x = 25 wristwatches.

If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution. STEP 1: Consider the figure in part (a). Since this region is simply a triangle, you may use precalculus methods to solve this part of the problem. First determine the height of the triangle and the length of the triangle's base. height 4 units units base 5 STEP 2: Compute the area of the triangle by employing a formula from precalculus, thus finding the area of the shaded region in part (a). 10 square units STEP 3: Consider the figure in part (b). Since this region is defined by a complicated curve, the problem seems to require calculus. Find an approximation of the shaded region by using a graphical approach. (Hint: Treat the shaded regi as…
