Question 253637
A radioactive substance has an initial mass of 100 grams and its mass halves every 4 years. Write an expression that shows the number of grams remaining after x years.
:
I would use the formula: A = Ao*2^(-x/4)
Where:
A = resulting amt
Ao = initial amt
x = no. of yrs
4 = half-life of the substance (yrs)
