It is said that if you are with someone else, you do not have to outrun the wolf, you just have to outrun the other person.
Suppose that a wolf can run 15 m/s, you can run 10 m/s and your friend can run 5 m/s.
You start 15 meters away from the wolf and your friend starts 20 meters, away from the
wolf.
Set up three equations and then answer using your perfered method
(table/graphing/theory): Who gets caught first and when (in seconds)?

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60
