Answer:
Point 1: (-5.03, 0.001)
Point 2: (0, 0.333)
Point 3: (3.068, 9.698)
Step-by-step explanation:
To minimize the cost, we take the straight distance from the refinery to the other side of the river as 2 km. Also, the 7 km will be the distance that has to be traveled by the pipeline in land. The total cost, C, is therefore,
total cost = (2 km)($800,000/km) + (7 km)($400,000 /km)
total cost = $4,400,000
Thus, the total cost of the pipeline is approximately $4,400,000.00.
