## VIDEO: Algebra Applications: Data Analysis, Segment 4: What is an Adjustable Rate Mortgage?

### Another factor in the mortgage crisis was the use of adjustable rate mortgages. Students run a number of scenarios to test adjustable rate mortgages, while also taking into account the state of the housing market during the time of the mortgage crisis. This video includes a Video Transcript: https://www.media4math.com/library/video-transcript-algebra-applications-data-analysis-segment-4-what-adjustable-rate-mortgage A Promethean Flipchart is available for this video: https://www.media4math.com/library/promethean-flipchart-algebra-applications-what-adjustable-rate-mortgage

## VIDEO: Algebra Applications: Variables and Equations, Segment 3: River Ratios.

### Why do rivers meander instead of traveling in a straight line? In going from point A to point B, why should a river take the circuitous route it does instead of a direct path? Furthermore, what information can the ratio of the river’s length to its straight-line distance tell us? In this segment the geological forces that account for a river’s motion are explained. In the process, the so-called Meander Ratio is explored. Students construct a mathematical model of a meandering river using the TI-Nspire. Having built the model, students then use it to generate data to find the average of many Meander Ratios. The results show that on average the Meander Ratio is equal to pi.
