Question

Sorry I'm working on a practice test and I've been stuck for a long time. This is the problem. I would really appreciate it if you could please help me out

Town P is located 5 miles north of an ocean. City planners want to connect Town P to Power Plant Q, which is located off shore (in the ocean) several miles away.

The problem is continued in the comments since it's so long :(

Answer 1

If we draw on a coordinate system, we can place Town P at (0,5) and Power Plant Q (10, -3). The x-axis forms the beach, separating the land (everything above the x-axis) from the sea (everything located below the x-axis).

It costs $5000 to place a mile of power lines on land and $10000 to place a mile of power lines in the ocean

Answer 2

The actual problem is

a) find the least expensive way to connect the town to the power plant (how many miles of power plant should be built on land, how many should be built in water, and how much will the project cost

b) Find the most expensive way to connect the town?

Answer 3

were the coordinates specifically given or did you make them up?

Answer 4

they were given

Answer 5

distance from town to shore is x
distance from plant to shore is y
