{a} (bl (Cl Find the coordinates of the points on the curve .r3 11:3 =16 which are nearest to the point (0.6). Car A is travelling west at 50 mi Hi and car B is travelling north at 60 mi f h. Both are headed for the intersection of the two roads. At What rate are the cars approaching each other when car A is 0.3 mi and car B is 0.4 mi from the intersection? An offshore oil well is located in the ocean at a point W, which is 5 miles from the closest shorepoint A on a straight shoreline The oil is to be piped to a shorepoint B that is 8 miles from A by piping it on a straight line underwater from W to some shorepoint P between A and B and then on to B via a pipe along the shoreline, If the cost of laying pipe is $100,000 per mile under water and $75,000 per mile over land, where should the point P be located to minimize the cost oflaying the pipe
