This math topic focuses on solving exponential decay problems with mismatched time units in a continuous context. It covers determining the decay rate, \( r \), from exponential functions represented by real-world scenarios like declines in toxin concentration, bird populations, radioactive materials, bacteria populations, and whale populations. The problems require manipulating exponential equations to isolate and solve for the decay rate, involving calculations with logarithms and different time units. This includes transforming given formulas to determine the most appropriate way to calculate decay rates from initial and final conditions over specific times. Each problem includes several answer options for students to choose from.
