The exponential function for the amount of the dose that remains is given by:
[tex]A(t) = 10(0.95)^t[/tex]
A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
In this problem, we have that the initial amount is of 10 units, with a decay rate of 5%, hence A(0) = 10, r = 0.05, and the equation is given by:
[tex]A(t) = 10(0.95)^t[/tex]
