A company wants to run a pipeline from a point A on the shore to a point B on an island which is 6 km from the shore. It costs 4000 per kilometer to run the pipeline on shore, and 5000 per kilometer to run it underwater. There is a point C on the shore so that BC is at right angles to AC. The straight shoreline is the line AC. The distance AC is 9 km. Determine the minimum cost. 44000 54000 34000 64000
