ASC 315 - Summer 2017 Page 1 of 2 ASC 315 Project DUE: Thursday, July 20, 2017 by 11:59 pm Submit via blackboard instructions. This is an individual project. It is worth 100 points. Your work must be clear and neat. You must document your resources (where appropriate) when answering the parts of the project. This is a requirement as part of the points given in this project. Part 1: Viewing Graphs - Hot Water Heater Operation (20 pts) The tank, to the right, is of the type normally found in a flat in Italy. Cold water enters it at the bottom and hot water is drawn off from the top whenever someone uses a hot tap. Twice a day the water is heated by the central heating boiler the tank is lagged to reduce heat loss. The graph below shows the temperature variations in a domestic hot water tank. Two temperature sensors were attached to the tank: one near the top and one near the bottom. The graph shows a 24-hour period starting and ending at midnight. ASC 315 - Summer 2017 Page 2 of 2 Answer the following questions using the information, pictures, and graphs above. 1. 2. 3. 4. At what times was the water being heated up? Explain how you determined your answer. What was the first time that someone ran a hot tap? Explain how you determined your answer. When was the hottest water being used? Explain how you determined your answer. Why does the bottom graph vary so much more than the top graph? Part 2: Understanding Types of Graphs (80 pts) In chapter 6 you are presented with three different equations that can model real world applications. The three equations are linear equations, exponential equations, and quadratic equations. When we use the equation to explain an application, we generally refer to it as a model. Type of Models: 1. Linear model 2. Exponential model 3. Quadratic model For this part of the project I would like for you to provide the following for each model a. An explanation of the mathematical equation. b. Provide two real world applications for each model where one of the applications refer to a recent technology. (Do not forget to document your resources in answering questions and proving examples for this part.) DOCUMENT YOUR RESOURCES USED IN ANSWERING THE QUESTIONS
