plug these #s into the half-life formula

230 = 860(.5)^t/5

exponential growth model

x = ae^bx

exponential decay model

x = ae^-bx

gaussian model

y = ae^-(x-b)²/c

logistic growth model

y = a/1+be^-rx

natural logarithmic model

y = a+b ln x

common logarithmic model

y = a+b logx

half-life formula

A = Pe^rt
