    depreciate means decrease so you have to use this formula \[\huge\rm y = a(1-r)^t\] a = initial amount r= rate t = years substitute values solve for y

    so the equation looks like y=2859(1-.21)^3

    A radio active isotope decays according to the exponential decay equation where t is in days. Round to the thousandths place. For the half life: The half life is the solution (t) of the equation : a/2=ae^−3.568t
