I'm cramming for midterms so if you can break down each step it would be greatly appreciated :) Calc review: 1) You wish to make a 9 sectioned pen with 1000 feet of fence. What dimensions will give the most area and what is that area? 2) A kite is launched 100 feet from a boy and is 50feet in the air. It is going straight up at 15 ft/sec. How fast does the boy need to let the string out? 3) Use the definition of the derivative to find the derivative of y = 4x2 + x - 8
