Question

The mass of a substance, which follows a continuous exponential growth model, is being studied in a lab. The doubling time for this substance was observed to

be 8 hours. There were 3.6 mg of the substance present at the beginning of the study.

Answer 1

In order to find the continuous growth rate, we need to convert the model to the form P(t) = P0ekt. So, we need to solve for k in 1.042 = ek. Taking the natural log of both sides, we get k = ln(1.042) ≈ . 04114.
