An island is 4 miles offshore in a large bay. A water pipeline is to be run from a water tank on the shore to the island. The pipeline costs $50,000 per mile in the ocean and $20,000 per mile on the land. The water company would like to run the pipeline for the cheapest amount possible, so they have called on you (with your superior math and trigonometry skills) to help. 1. Just to get yourself started, you decide to make the angle in the diagram be
=10∘

a. What is the length of the pipeline in the ocean? miles__ (round to two decimal places)

b. What is the cost of the pipeline in the ocean? $__ (use your rounded answer from part a)

c. What is the length of the pipeline on land? miles__ (round to two decimal places)

d. What is the cost of the pipeline on land? $ __ (use your rounded answer from part c)

e. What is the overall cost of the pipeline? $__ (use your rounded answers from part b and d)

2. Since your answers to question 1 were based on one angle (and rounded answers), you decide to recalculate the overall cost based on another angle and giving a more precise answer by NOT rounding mid work.

Given
=67∘
Determine the total final cost for the entire pipeline.

The totally cost of the pipeline is $__
