Only need to complete Q1c and Q1d part, please use matlab and take a screenshot

Background You have been asked to manage a project to install a pipeline from an offshore gas platform to an onshore gas processing plant. A rough schematic is shown in Figure 1. The aim is to determine the cheapest design solution possible. The platform is D km offshore, and L km along the coastline from the processing plant. The pipeline will follow a straight line from the platform to the shore, and hit land at a point that is a distance x from that point on the shore that is closest to the platform. It is assumed that the coastline is a straight line.

Note: Q1a-Q1f are independent from Q1g-Q1h. Note: figure(1)' in Q1a.m contains a plot marking the locations of the offshore gas platform and onshore gas plant, which will be used in Q1b. Q1a "Company 1" has quoted the cost of laying a subsea pipeline of $Cs per kilometre (regardless of water depth) and the cost of laying onshore pipeline at $C01 per kilometre. In the Q1a.m file, create a function handle for the cost of the pipeline with inputs x. Calculate the cost of the pipeline for 0
