Question
Forty grams of a certain radioactive material disintegrates to 16 grams in 220 years. How much of this material is left after 300 years?
Step 1
We know that the decay formula is N(t) = N0 * e^(-λt), where N(t) is the amount of material left after time t, N0 is the initial amount, λ is the decay constant, and t is the time. We are given that 40 grams of the material decays to 16 grams in 220 years. So, we Show more…

A radioactive substance has a half-life of 700 years. If there were 10 grams initially, how much would be left after 300 years?
Transcendental Functions
Exponential Growth and Decay
A radioactive element decays exponentially in proportion to its mass. One half of its original amount remains after $5,750$ years. If $10,000$ grams of the element are present initially, how much will be left after $1,000$ years?
