VIDEO: Algebra Applications: Quadratic Functions, Segment 4: MedicineFrom the time a baby is born to the time it reaches 36 months of age, there is dramatic growth in height and weight. An analysis of CDC data reveals a number of quadratic models that doctors can use to monitor the growth and development of children. 

VIDEO: Algebra Applications: Variables and Equations 
VIDEO: Algebra Applications: Variables and EquationsIn this episode of Algebra Applications, two realworld explorations are developed: Biology. Analyzing statistics from honey bee production allows for a mathematical analysis of the socalled Colony Collapse Disorder. Geology. Why do rivers meander instead of traveling in a straight line?

VIDEO: Algebra Applications: Variables and Equations, Segment 2: Honey Production.Honey bees not only produce a tasty treat, they also help pollinate flowering plants that provide much of the food throughout the world. So, when in 2006 bee colonies started dying out, scientists recognized a serious problem. 

VIDEO: Algebra Applications: Variables and Equations, 3 
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? 

VIDEO: Algebra Applications: Inequalities 
VIDEO: Algebra Applications: InequalitiesIn this episode of Algebra Applications, two realworld explorations of inequalities are developed. Hybrid Cars. An examination of the equations and inequalities that involve miles per gallon (mpg) for city and highway traffic reveals important information about hybrid cars and those with gasolinepowered engines. 

VIDEO: Algebra Applications: Inequalities, 1 
VIDEO: Algebra Applications: Inequalities, Segment 1: Hybrid CarsWith the increasing demand worldwide for cars, the cost of gasoline continues to rise. The need for fuelefficient cars makes hybrids a current favorite.

VIDEO: Algebra Applications: Inequalities, Segment 2: Floods in VeniceThe city of Venice is slowly sinking into the Adriatic Sea. So what does a city whose streets are full of water do about flooding? Venice experiences a great deal of flooding, and with the expected rise of sea levels over the next century, this ancient city is in peril. 

VIDEO: Algebra Applications: Functions and Relations 
VIDEO: Algebra Applications: Functions and RelationsIn this episode of Algebra Applications, students explore the following scenario: Scientists use conic sections to map the trajectories of spacecraft in flight. The setting for this episode is a planned future flight to Mars. 

VIDEO: Algebra Applications: Functions and Relations, 1 
VIDEO: Algebra Applications: Functions and Relations, Segment 1: Introduction.Scientists use conic sections to map the trajectories of spacecraft in flight. The setting for this episode is a planned future flight to Mars. As the ship travels from Earth to Mars, parabolic, circular, and elliptical paths are explored. 

VIDEO: Algebra Applications: Functions and Relations, 2 
VIDEO: Algebra Applications: Functions and Relations, Segment 2: Parabolic Paths.The liftoff and preorbital path of the rock is described by a parabola. Students explore the properties of parabolas from the standpoint of the parametric equations that describe the horizontal and vertical directions of motion for the rocket. 

VIDEO: Algebra Applications: Functions and Relations, 3 
VIDEO: Algebra Applications: Functions and Relations, Segment 3: Circular Paths.The path of a rocket orbiting the Earth can be modeled with the equation of a circle. Students explore the quadratic relation and the parametric equations that can be used to model the path of a spacecraft orbiting Earth. 

VIDEO: Algebra Applications: Functions and Relations, 4 
VIDEO: Algebra Applications: Functions and Relations, Segment 4: Elliptical Paths.The planets orbiting the sun follow elliptical paths. In fact, the trajectory of a spacecraft traveling to Mars would also be elliptical. Students explore these various ellipses. 

VIDEO: Algebra Applications: Data Analysis 
VIDEO: Algebra Applications: Data AnalysisIn this episode of Algebra Applications, students explore the dramatic events of 2008 related to the mortgage crisis. Brought about principally through mortgage defaults, the effect on the overall economy was severe. 

VIDEO: Algebra Applications: Data Analysis, 1 
VIDEO: Algebra Applications: Data Analysis, Segment 1: IntroductionIn this introductory segment students learn about the mortage crisis of 2008. In the process they get a brief introduction to what a mortgage is. This is part of a collection of videos from the Algebra Applications video series on the topic of Data Analysis. 

VIDEO: Algebra Applications: Data Analysis, 2 
VIDEO: Algebra Applications: Data Analysis, Segment 2: What Is a Mortgage?The time value of money is at the basis of all loans. Students learn about the key factors that determine monthly mortgage payments and use the TINspire to create an amortization table. This table is used throughout the rest of the program to explore different scenarios.

VIDEO: Algebra Applications: Data Analysis, Segment 3: What Is a What is a Subprime Mortgage?Having learned the general features of a mortgage, students learn the specifics of a subprime mortgage. With this comes the notion of a credit score, and with credit scores come the probabilities for a loan default. 

VIDEO: Algebra Applications: Data Analysis, 4 
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.
