Problem of the Week: 2014-10-21

Due Tuesday, October 21 at 5:00 pm

A triangle with vertices (5, 5), (7, -3), and (8, 1) is reflected across the line x = 7 to create a second triangle.  What is the area of the union of the two triangles?

All answers should be clearly explained.  Mathematics is about logic and reasoning, not just about getting a number and putting a box around it.

Submit your answers to the Math/Stat Office, Room 107, Adel Mathematics Building. If your instructor is giving you extra credit for doing POTW, please indicate the instructor's name and the class. Please put the due date (e.g. 2014-01-21 for January 21, 2014) on your submission. Contact with questions.

Winning solutions and a summary of scores will be posted on the POTW bulletin board. This bulletin board is located near the bottom of the big stairway joining the first and second floor of the Adel Math Building.
