Algebra Application: When Will Space Travel Be Affordable? 
In this Algebra Application, students examine the budding industry of commercial space travel. Using data from the Bureau of Transportation Statistics, students build a mathematical model from historical airfare data. This model is used to predict when commercial space travel will become affordable. This also includes a discussion of inflationadjusted costs and the future value of money. Topics covered:

Closed Captioned Video: Algebra Applications: Exponential Functions 
In this episode of Algebra Applications, students explore earthquakes using exponential models. In particular, students analyze the earthquake that struck the Sichuan Province in China in 2008, months before the Beijing Olympics. This dramatic, realworld example allows students to apply their understanding of exponential functions and their inverses, along with data analysis and periodic function analysis.

Closed Captioned Video: Algebra Applications: Exponential Functions, Segment 4: How Is Earthquake Magnitude Measured? 
An earthquake is an example of a seismic wave. A wave can be modeled with a trigonometric function. Using the TINspire, students link the amplitude to an exponential function to analyze the dramatic increase in intensity resulting from minor changes to magnitude.

Closed Captioned Video: Algebra Applications: Logarithmic Functions, Segment 1: What Are Logarithms? 
The mathematical definition of a logarithm is the inverse of an exponential function, but why do we need to use logarithms? This segment explains the nature of some data sets, where incremental changes in the domain result in explosive changes in the range. As a result, logarithms allow for the a way to present and analyze what would otherwise be unwieldy data.

Closed Captioned Video: Algebra Applications: Logarithmic Functions, Segment 2: Hearing Loss 
We live in a noisy world. In fact, prolonged exposure to noise can cause hearing loss. Students analyze the noise level at a rock concert and determine the ideal distance where the noise level is out of the harmful range. Using the TINspire’s Geometry tools, student create a mathematical simulation of the decibel level as a function of distance.

Closed Captioned Video: Algebra Applications: Logarithmic Functions, Segment 3: Tsunamis 
In 1998 a devastating tsunami was triggered by a 7.0 magnitude earthquake off the coast of New Guinea. The amount of energy from this earthquake was equivalent to a thermonuclear explosion. Students analyze the energy outputs for different magnitude earthquakes. Using the Graphing tools, students explore the use of a logarithmic scale to better analyze exponential data.
