The "half-life" of Californium-242 is 3.49 minutes. That means that half of the isotope we have will decay in 3.49 minutes. In another 3.49 minutes half of the amount of the isotope we had at
the end of the first 3.49 minutes will decay. This process will continue indefinitely where we lose
half of the remaining isotope every 3.49 minutes. For this situation, assume we have 15 grams
of Californium-242. Let x represent the number of 3.49 minute intervals.
Describe this process using recursion.
40 = 3.49

Describe this process using an explicit formula.
How much Californium-242 isotope will remain after 10.47 minutes? Remember that x
represents the number of 3.49 intervals)
