    Our assignment is to solve problem 103 on page 605, parts a and b, and problem 104 on page 606, both a and b, of our text book, Elementary and Intermediate Algebra. The assignment revolves around sail boat stability and speed. The formulas we will use can give you a good starting point in planning your craft and journey if used wisely. Knowing the restrictions of a ship’s stability and maximum speed is important in real world applications. It can be applied to the design of everyday sail boats and racing boats to ensure the safety of these craft. A formula along these lines can also be used for pleasure yachts, cruise ships, and cargo craft. Knowing the stability and speed of your craft is important to safety as you will know if the sea is rough if you can navigate it safely. This also applies to the aforementioned larger craft as they can decide whether to plot a course around heavy seas or proceed as originally scheduled. The speed of the craft can be used to determine how long it will take to reach your destination. Of course there will be many other variables that would need to be taken into account, like weight of cargo or anything else you may be carrying, but it will give you a good starting point for your journey.…
