A 100 foot cable is used to haul a 300 pound load from the ground to the top of a 100 foot tall building. The cable has varying density so that the density at a height h feet above the ground is δ ( h ) = 30 − 2 h pounds per linear foot. The load being lifted has a leak, and leaks at a constant rate, so that by the time it reaches the top of the building it weighs only 250 pounds. Determine the work performed by the time the load (or what's left of it) reaches the top of the building.

An electrical tower of height 12 feet stands 21 feet away from a 20-foot tall building. A support cable stretched from the top of the tower to a point on the ground and then back to the top of the building. How far from the base of the tower should the cable be attached on the ground so that the least amount of total cables is used? You must set up an appropriate function to get credit.
