Question 450253
the half-life of cesium-137 is 40 years.
 suppose we have a 34-g sample.
 find a function that models the mass remaining after t years.
:
The radiology decay formula
A = Ao*2^(-h/t)
Where
A = amt after t yrs
Ao = initial amt
t = time in yrs
h = half-life of substance, in yrs
:
A = 34*2^(-t/40)
