There was a sample of 550 mg of radioactive substance to start a study since then the sample has decayed 2.9% each year write an exponential function showing the relationship between Y&T

Answer 1

At the end of a year, you are left with 97.1% of the amount at the start of the year.

m(t) = m₀ (0.971)^t

m₀ = 550 mg

t = years elapsed since the amount was m₀
