Asmall house was built on an island off a perfectly straight shoreline. the point b on the shoreline that is closest to the island is exactly 6 miles from the island. eight miles east of b is the closest source of fresh water to the island. a pipeline is to be built from the island to the source of fresh water by laying pipe underwater in a straight line from the island to a point q on the shoreline between b and the water source, and then laying pipe on land along the shoreline from q to the source. it costs 6000 dollars per mile to lay the pipe under the water and 3750 dollars per mile to lay pipe on land. how far east of b should q be located in order to minimize the total construction costs
