Radiometric Dating BBC - History - Archaeology - Carbon Dating Dating Exhibit How about carbon dating?

These problems will require you to know how to evaluate exponential expressions and solve exponential equations. If the information for time is given in dates, you need to convert it to how much time has past since the initial time.If you need a review on these topics, feel free to go to Tutorial 42: Exponential Functions and Tutorial 45: Exponential Equations. For example, if the model is set up at an initial year of 2000 and you need to find out what the value is in the year 2010, t would be 2010 - 2000 = 10 years.Natasha Glydon Exponential decay is a particular form of a very rapid decrease in some quantity.One specific example of exponential decay is purified kerosene, used for jet fuel.Include recognizing even and odd functions from their graphs and algebraic expressions for them. Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table). Identify the effect on the graph of replacing f(x) by f(x) k, k f(x), f(kx), and f(x k) for specific values of k (both positive and negative); find the value of k given the graphs.    In this tutorial I will step you through how to solve problems that deal in exponential growth and decay.

Note that the purpose of this task is algebraic in nature -- closely related tasks exist which approach similar problems from numerical or graphical stances.

The standards do not prescribe that students use or know with log identities, which form the basis for the "take the logarithm of both sides" approach.

The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.

In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.
