Question:

The half-life of a radioactive substance is 560 years. If there are 400 grams of the radioactive substance initially, construct an exponential model for the amount remaining (in grams) after {eq}t {/eq} years.

Exponential Model:

A mathematical illustration of a relationship between two variables, where one variable changes at a pace proportional to its current value, is called an exponential model. Population increase, compound interest, radioactive decay, and many more phenomena requiring exponential development are all typically described using exponential models. They offer a practical tool for forecasting future values or extrapolating past values from the trend shown.

We can use the formula: to build an exponential model for the quantity of radioactive material left (in grams) after t years.

$$A = A_{0}...
