An island is 4 miles offshore in a large bay. A water pipeline is to be run from a water tank on the shore to the island, as in the figure. The pipeline costs 60 thousand dollars per mile in the ocean, and 40 thousand P dollars per mile on the land. What pipeline configuration will cost the least? Fill in the table below (2 pts for values, 2 pts for the formulas) Length of pipeline under water: Distance to P on shore (no pipeline there) 0 20 1.
