Setting Up Equations Each of Exercise S-1 through S-4 poses a question that can be answered by solving an equation. Given the appropriate equation. Note that you are not asked to solve the equation.
Argon-39 is a radioactive isotope of argon. Initially a sample of argon-39 contains 10 grams, and the amount remaining after t years is given by
The half-life is the time required for the amount of argon-39 to be reduced by half. The half-life of argon-39 is the solution of an equation. Find that equation.
