Modeling exponential functions for the decrease of a population

The video tutorial covers exponential and modeling equations, explaining their components and application. The teacher demonstrates solving a problem using these equations, highlighting common mistakes and corrections. The focus is on understanding the equation's variables and applying them correctly to find the solution.

What does the variable 'a' represent in the equation a(t) = a * (1 + r)^T?

What is the initial population given in the problem?

How do you convert a percentage rate into a decimal for calculations?

Explain the significance of the base 'B' in exponential growth or decay.

How does the teacher determine whether the population is increasing or decreasing?

What mistake did the teacher make regarding the population calculation?

What was the final population calculated after 18 years?
