The Law of exponential Decay is an application of antiderivatives. Just as
something can decay, it can grow as well. Both decay and growth are
included in the theorem below.
Exponential Growth and Decay
If y is a differentiable function of t such that y > 0 and y ' = ky, for some
constant k, then y = Cekt. C is the initial value of y, and k is the
proportionality constant. Exponential growth occurs when k > 0, and
exponential decay when k < 0.
Situation
10 grams of plutonium isotope Pu239 is released in some far off nuclear
research facility. They have exposed the 10 grams of Pu239 to air, s

Best ResponseYou've already chosen the best response.0seems like there are some information missing for this question. 10grams of Pu239 would be the initial value, which is the constant C. You will need either half life of decay constant to determine the amount of isotopes in terms of time.
