(0} 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 ofiaying the pipe? \fa Evaluate the following integral: (3+ tanx -dx COS' X [5] b) Find the area of the region enclosed by the parabolas y=x and y=2x-x2.
