Q9 Rectangular Area 2 Points Suppose that r and y axis have been drawn on the ground. A nearby lake has a coast that looks like y = ed. We want to make a rectangular lawn so that one corner is at (0, 0) and the opposite corner is along the coastline of the lake and has coordinates (2, y). The area of the rectangular lawn is A(2) = re-z. (Please see the graph below.) y = ex (x, y) y X Q9.1 x-value for maximum 1 Point Find the value of r that gives the maximal area of such a rectangle. (You do not need to compute the maximal area. Just enter the value of a that gives you the maximal area.) Enter the answer as a decimal number (without units). Round to three decimal places, if needed. Enter your answer here Q9.2 Minimum Area 1 Point What is the minimum value of the area function over the interval [0, 10]? Enter the answer as a decimal number (without units). Round to three decimal places, if needed. Enter your answer here
