'i'he rectangular plot in Figure 2;! has she 100 ft by 200 ft. Pipe Is to be laid from A to a point P on side BC and from there to C. The cost of laying pipe along the side of the plat is $ 45m and the cost through the plat is $ F'Oftt {since it Is underground]. (a) Let x] be the total cost. where it Is the distance from P to B. Determine x), but note that f is discontinuous at x = 0 (when x = D. the cost of the entire pipe Is $ 46m]. What Is the minimal cost? (a) It the east along the sides a s am, what is the minimal cost? :] B P C A 200 FIGURE 26 if you don't get this in 4 tries, you can get a hint. Brendon is on one side of a river that is 50 m wide and wants to reach s point 300 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 2 mfs and run at 4 mfs. (Use decimal notation. Give your answer to at least two decimal places.) The minimum amount of time Is C] seconds help {fractions}
