College Admissions: Financial Planning (Informative/Explanatory)

As college costs continue to rise faster than the general rate of inflation, young college students are increasingly finding themselves saddled with debt and forced to make complex financial decisions. In response, some colleges now channel freshmen through personal finance seminars in which students learn how to budget, how to understand loan terminology, and how to avoid common financial pitfalls.

Think about the financial challenges you may face when you attend college. You may also want to interview a college student you know about his or her challenging experiences.

Math Video Improves Understanding (Informative/Explanatory)

We are not usually asked to describe or discuss math concepts except in a math class, and we are very rarely asked to write about them. However, writing about math concepts can improve learning, reinforce our understanding of the concepts, and strengthen our understanding of the vocabulary and terminology. After viewing a math video, think about the new concepts introduced, how they relate to what you have already learned, and how you will use them in the future. How was the video able to illustrate the concepts to improve your understanding?

In a well-developed essay, discuss the math concepts of the video and how the video impacted your understanding of those concepts. Include facts and details to support your discussion.

Using Geometry to Plan a Memorial Park (Informative/Explanatory)

You are on the Buildings and Grounds Committee in your city and have been assigned the task of creating a memorial park for veterans who have served in the community. The park will consist of a playground, bathrooms, a parking lot, a memorial fountain, and a spotlight for the fountain. The playground, bathrooms, and parking lot will be connected by sidewalks in the shape of a triangle. The memorial fountain will be placed within this triangle, equidistant from the sidewalks that connect the playground, bathrooms, and parking lot. A spotlight for the fountain will be placed equidistant from the playground, bathrooms, and parking lot. A canopy that will be used for the dedication of the park will cover the area between the playground, bathrooms, and parking lot. The balance point of the canopy must be determined for the center pole or the canopy will collapse.

After determining the centroid, incenter, and circumcenter of the triangle of sidewalks connecting the playground, bathrooms, and parking lot, suggest which of these three points would be the best place for the memorial fountain, spotlight, and canopy's center pole. In a multi-paragraph essay, report your findings for the location of the three objects, supporting their locations with the principles of geometry.

Using Triangles to Find a Plane (Informative/Explanatory)

The president of the United States has asked you to assist in finding a plane that has gone down over the Indian Ocean. You have been given the task of choosing a tracking system company to find the plane. You want to locate the plane as quickly as possible.

There are four tracking system companies available for use. Each company uses satellites that will take certain measurements to create a triangle around the possible crash site.

The triangle will be formed from the following three points:

The airport from which the plane departed

The point where the plane made a counterclockwise turn

The plane's last known position

Analyze the sample data given by each company to select the one that will find the plane most efficiently. In a multi-paragraph essay, justify your selection of the company to the president. Use the results of your analysis of each company's sample data to support your justification.

Below is sample data given by each company:

Company 1:

Acute Satellite Inc. can provide the following information by using their satellites:

An airplane takes off from Kuala Lumpur going northwest at an angle of 73°. The plane turns counterclockwise 35°. The last known angle is a counterclockwise turn of 72°.

Company 2:

Right Distance Inc. can provide the following information by using their satellites:

An airplane takes off from Kuala Lumpur going north at an angle of 90°. The plane travels 1,250 km, and then turns counterclockwise 35°.

Company 3:

Butte Inc. can provide the following information by using their satellites:

An airplane takes off from Kuala Lumpur going northwest at an angle of 38°. The plane travels 2,500 km, and then turns counterclockwise and travels another 1,750 km.
