Question

The half-life of a certain radioactive material is 85 days. An initial amount of the material has a mass of 801kg. Write an exponential function that models the

decay of the material.

Answer 1

m(t) = 801 * (1/2)^(t/85)

Explanation:

m(t) = 801 * (1/2)^(t/85)

m(t) is the mass after t days
