Centerville is the headquarters of Greedy Cablevision Inc. The cable company is about to expand service to
two nearby towns, Springfield and Shelbyville. There needs to be cable connecting Centerville to both towns.
The idea is to save on the cost of cable by arranging the cable in a Y-shaped configuation.
Centerville is located at (10, 0) in the cy-plane, Springfield is at (0, 8), and Shelbyville is at (0,
cable runs from Centerville to some point (x, 0) on the x-axis where it splits into two branches going to
Springfield and Shelbyville. Find the location (x, 0) that will minimize the amount of cable between the 3
towns and compute the amount of cable needed. Justify your answer.
8). The
To solve this problem we need to minimize the following function of x:
f(x)
We find that f(x) has a critical number at x =
To verify that f(x) has a minimum at this critical number we compute the second derivative f''(x) and find
a positive number.
that its value at the critical number is
Thus the minimum length of cable needed is
