An oil company wants to lay a pipeline from its offshore drilling rig to a storage tank on shore, as illustrated in the accompanying figure. The rig (point W) is 5 miles offshore (point A), and the storage tank (point B) is 8 miles down the shoreline. The costs of laying pipe underwater are $9,000 per mile and along the shoreline are $3,000 per mile. Point P is the point on shore where the underwater pipe connects with the shoreline pipe. Set up an equation for the total cost. State domain, state units. d√25+2² A 2-10 1 2 3 4 5 6 3
