GRADED EXERCISE 5: 1 3. A 6-ft man walks away from a 9-ft lamppost at a rate of ft/sec. If the light at the top of the lamppost produces the man's shadow, how fast is the tip of his shadow moving when he is 5 ft from the pole? 4. What is the smallest perimeter possible for a rectangle of an area 25m²? (The perimeter of a rectangle is 21+ 2w, where l and w are, resp., the length and width of the rectangle, while the area is lw.)
