An island is 3.5 mi from the nearest point on a straight shoreline: that point is 8 mi from a power station. A utility company plans to lay electrical cable underwater from the island to the shore and then underground along the shore to the power station. Assume it costs $2400/mi to lay underwater cable and $1200/mi to lay underground cable. Island Solve this problem by choosing to either solve part a or part b. a. At what point should the underwater cable meet the Cable shore in order to minimize the cost of the project? 3.5 mi Power station Shore 8 mi - b. Solve the problem in #2 again, but this time minimize the cost with respect to the smaller angle e between the underwater cable and the shore.
