Question 1030965: A scientist has 68 grams of a radioactive substance that decays at an exponential rate. Assuming k = -0.4, how many grams of radioactive substance remain after 10 days (use continuous growth/decay)?
You can put this solution on YOUR website! A scientist has 68 grams of a radioactive substance that decays at an exponential rate. Assuming k = -0.4, how many grams of radioactive substance remain after 10 days.
-----
A(t) = P*e^(-0.4t)
-----
A(10) = 68*e^(-4) = 1.25 grams
