Problem 3:

Find the Area/dimensions of the following problem with the perimeter of 18ft.

 This problem is more complex because instead of having just a regular flat top, the window has an arc. Because of this, you have to find 1/2 of the circumference using the radius which is 1/2 of x.

 Once you find y you can plug it into the area equation so you just have to solve for x.

 Once you have x, you plug it back into your perimeter equation to find the final y value.

This problem incorporates equation solving, finding the vertex, Solving for various variables, etc.

Problem 4:

Allie's Reflection:

We chose to do these concepts because they cover areas that Alexa and I struggled with throughout the trimester. These problems include various concepts that we covered throughout the year. Those concepts including: completing the square, factoring, finding inverses, finding domain, finding range, finding the vertex, long division with radicals, finding an equation using 3 points, etc. This project ended up being easier than I anticipated when we got the outline. It was also a very good way to review for the final exam because it took me through the problems more in depth than I had looked before. I did not really learn anything new from this project, it just helped me review for the final mostly. 

Alexa's Reflection:

The concepts we chose for this project were chosen because I thought they were interesting concepts and some of them i had trouble learning in the trimester.  These problems provide us with the best mathematical understanding because we used a wide variety of different concepts that we learned in class.  I did learn something from this assignment.  First, I became a lot better at finding a function with three given points.  Also, there was a problem that helped me a lot with area of shapes other than a rectangle.
