Lesson
Hamburger Disease
Using the ideas that you have learned in this section you should now be able to write equations to model Richard's, John's and Sadie's handling of the hamburger meat. Be careful in trying to write a function for Sadie's since you will have to consider three different situations - the first 2 hours, the next 20.5 hours and then the remaining time. This gives rise to what is referred to as a piecewise function since the resulting graph will have three distinct pieces to it to match each of the time periods.
You should now be able to write the final draft for the answers to questions (a) and (b).
Nitrogen- 14 to Carbon 14 Simulation
Using the ideas that you have learned in this section and the previous section you should now be able to to answer questions (a) (b) and (c).
Since such a large table of values is required it is a good idea to use an entire sheet of graph paper for the scatter plot. When attempting to find the equation for the curve of best fit, experiment with the various regression equations - quadratic, cubic, quartic, exponential, etc. Determine which is the best and why it is the best model.
