Question

The half-life of a certain radioactive material is 76 hours. An initial amount of the material has a mass of 794 kg.
Write an exponential function that models the decay of this material.

Answer 1

794(1/2)^(t/76)

Answer 2

half life T=76 hrs
initial amount of radioactive material N0=794 kg

Answer 3

we know radioactive constant lamda=1/T=1/76

Answer 4

N=N0 e^(-lamda *t)
N=76 e^(-1/76 *t)
