Solve the problem. Round to two decimal places where Docking Facility necessary. Supertankers off-load oil at a docking facility shore point 5 mi offshore. The nearest refinery is 9 mi east of the docking facility. A pipeline must be constructed connecting the docking facility with the refinery. The pipeline costs $300,000 per mile if 5 mi constructed underwater and $200,000 per mile if over land. Locate point B to minimize the cost of construction. Shore - A B Refinery 9 mi . . . O A. Point B is 5.66 miles from Point A. O B. Point B is 4.47 miles from Point A. O C. Point B is 3.51 miles from Point A. O D. Point B is 2.50 miles from Point A
