Suppose that a space probe is launched in 2012 with 2.0kg of ^238 Pu.
If the half-life of ^238Pu is 87.7 yr, write a function of the form A(t)= Ao(1/2)^t/h to model the quantity Qt of ^238Pu left after t years.
:
A = the amt remaining after t yrs (in kg)
Ao = initial amt (2kg)
t = time of decay
h = half life of the substance (87.7 yrs)
:
A%28t%29+=+2%2A%281%2F2%29%5E%28%28t%2F87.7%29%29
