The amount of a radioactive isotope present in a certain sample at time t is given by Upper A left parenthesis t right parenthesis equals 800 e Superscript negative 0.02838 t grams, where t years is the time since the initial amount was measured. How long will it take for the amount of the isotope to equal 524 grams?
Added by Miguel -Ngel E.
Step 1
We have the equation A(t) = 800e^(-0.02838t) and we want to find the value of t when A(t) = 524. So, we set up the equation: 524 = 800e^(-0.02838t) Show more…

The amount of a radioactive isotope present in a certain sample at time t is given by Upper A(t) = 500e^(-0.02839t) grams, where t years is the time since the initial amount was measured. How long will it take for the amount of the isotope to equal 317 grams?

The amount of a radioactive isotope present in a certain sample at time t is given by A(t) = 600e^(-0.02828t) grams, where t years is the time since the initial amount was measured. a. Find the initial amount of the isotope that is present in the sample. b. Find the half-life of this isotope. That is, find the number of years until half of the original amount of the isotope remains. a. The initial amount of the isotope that is present in the sample is [ ] grams.
