Applying radioactive decay to determine the percent left of compound

The video tutorial explains growth and decay models, focusing on the half-life of radioactive radium. It provides a step-by-step guide to solving for the decay rate and calculating the percentage of radium remaining after 100 years. The tutorial uses the formula Y = A * e^(RT) and demonstrates how to apply logarithms to solve for the decay rate. The conclusion shows that 96% of radium remains after 100 years, given its half-life of 1620 years.

How do you solve for the rate of decay (R) in the context of the radium problem?

What does the natural logarithm of both sides help to determine in the decay model?

Explain the significance of the value 0.96 in the context of the radium decay after 100 years.
