Round your answers to 4 decimal places. Half-Life in Days: Half-Life in Weeks: Half-Life in Years: Moving forward, we will use the half-life in days, so t will be measured in days. Using the formula for exponential decay (A - Age ) and the half-life for your radioactive isotope, calculate k. Make sure to get your value of k to 8 decimal places
