An engineer is designing a pipeline which is supposed to connect two points P and S. The engineer decides
to do it in three sections. The first section runs from point P to point Q, and costs $48 per mile to lay, the
second section runs from point Q to point R and costs $54 per mile, the third runs from point R to point S
and costs $44 per mile. Looking at the diagram below, you see that if you know the lengths marked x and y,
then you know the positions of Q and R. Find the values of x and y which minimize the cost of the pipeline.
Please show your answers to 4 decimal places.

An open-top rectangular box is being constructed to hold a volume of 150 in³. The base of the box is made
from a material costing 7 cents/in². The front of the box must be decorated, and will cost 11 cents/in².
The remainder of the sides will cost 3 cents/in².
Find the dimensions that will minimize the cost of constructing this box. Please show your answers to at
least 4 decimal places.
