Questions:
- Initially, there are 300 grams
of a particular radioactive substance. Using the formula, how many grams are
left at the 10-year point? Run the application and try stopping it at the
10-yr. mark.
Answer
- Assume the decay of another radioactive
substance is given by A = 300(e–0.03t). To
do this, you will need to change the coeffienct in front of t to –
0.03. If there are initially 300 grams of this substance, how much is left
at the 10-year point?
