6. An angler hooks a trout and reels in his line at Sin/sec. Assume the tip of the fishing rod is 13 ft above the water and directly above the angler, and the
Decreasing
fish is pulled horizontally directly toward the angler (see
at 5 in./s
figure). Find the horizontal speed of the fish when it is
21 ft from the angler. You need to define any variable 13 ft
you use in the context of the problem.
7. Find the point P on the line y=5x that is closest to the
point (78, 0). Include a picture and define any variable you use.
