The only thing that is constant is change
You may have heard the saying, “The only thing that is constant is change.” Paying attention to the change all around you can help you to better understand your world. For this week’s Exploration Problem, you will use estimation techniques to identify how a topic of your interest has changed and is changing over time.
Choose a topic of interest where you can see a change.
· Review almanacs, newspapers, magazines, or search on the Internet to find two graphs from the topic of interest you have chosen that show data changing from year to year that you find interesting. Choose mathematical models in the form of graphs: In one graph, the data values should be increasing relatively steadily. In the second graph, the data values should be decreasing relatively steadily. Include the images of your graphs. You may insert the image into a Microsoft Word document. Make sure one is showing an increase and one is showing a decrease.
Cite the resources from where the graphs came from.
Create a 1- to 2-paragraph summary including the following:
An explanation of the topic you chose and the data that has changed from year to year that you find interesting A description of the mathematical models, in the form of graphs, used to demonstrate how the data has changed
A justification of why you think things are changing An explanation of how you think this change might affect you in the near or distant future A prediction about what might occur in the future An identification and presentation of any circumstances that might affect the accuracy of the prediction

2. The members of a family of four (two parents and two children) are trying to be more conscious of their water usage. To find opportunities where they might make the most impact, they researched the average household water consumption for various uses. They already have a new house with efficient appliances, which will decrease water usage for the dishwasher and clothes washer. Help them determine where they can make the most impact with their water usage.

Imagine using math to explain how you know your friends and acquaintances. Were any of the people in your life introduced to you through another friend or acquaintance?
In this Discussion, you will create a visual representation that models relationships similar to the “six degrees of separation” as presented in your readings.
Chapters 14, paying special attention to the beginning of Section 14.1.
Select a favorite television series, movie, or novel with an extensive cast of characters that you consider interesting. Determine a relationship that exists among some, but not all, of the characters.
Consider the following graph, which represents the one-way airfare between five cities.
a. First use a graph tool like Graph Creator to represent the information in the table. Use vertices to represent the cities and weights on appropriate edges to show the airfares.
b. Next, assume that you are a salesman who lives in one of the cities (pick any city except for A) and required to fly to all four of the other cities and return to your home city. Describe how you would use the Nearest Neighbor Method to determine the optimal route. What is the total cost for this Hamilton circuit?
Mathematician Discussion
Choose a mathematician, then research his/her life and accomplishments. Select one thing he/she is famous for that relates to at least one of the Learning Outcomes for this course (see attached document).
Write a news article/blog using the “who, what, where, why, and how” method that makes a connection between the mathematician's accomplishment/publication and the necessary use of real numbers and arithmetic; polynomials and equations; or ratios, proportions, and percentages.
List the resources used at the end of your post using APA style.
Price Levels
Please respond to the following:
Select the areas of the price-setting process (define price window, set initial price, and communicate prices to market) that you believe to be the most important. Support your argument with evidence and/or examples.
classmate response: please respond to classmate post
In my opinion the price window is the most is the most important step of the price setting process. The overall goal is to set profit maximizing prices by capturing the appropriate amount of the differential value in each stage to affect the final price at each stage. The price window is set for every portion and characterized by the roof, the most noteworthy admissible value point, and the floor, the least allowable price point. We start the value setting process by building up the value window for every section and after that, in step two, a contract that window gave important destinations for the portion and potential client reactions to the new costs. So, setting the price range based on the differential value and the relevant cost is vital to the overall goal of maximizing your profit.

Elizabeth runs a factory that makes DVD players. Each R80 takes 9 ounces of plastic and 2 ounces of metal. Each D200 requires 6 ounces of plastic and 6 ounces of metal. The factory has 408 ounces of plastic, 324 ounces of metal available, with a maximum of 24 R80 that can be built each week. If each R80 generates $7 in profit, and each D200 generates $1, how many of each of the DVD players should Elizabeth have the factory make each week to make the most profit? R80=? , D200=?, best profit=?
