Answer:
<u>Exponential model</u>
where:
- y = value at "t" time
- A = initial value
- r = rate of growth/decay
- t = time (in years)
Given:
- y = 100 g
- t = 0 years
Substituting given values into the formula and solving for A:
Given:
- A = 100 g
- y = 50 g when t = 30.17
Substituting the given values into the equation and solving for r:
Therefore, the final equation is:
<u>Part (a)</u>
Q: From 100g how much remains in 80 years?
<u>Part (b)</u>
Q: How long will it take to have 10% remaining?
10% of 100 g = 10 g
<u>Part (a)</u>
Q: How much remains after 50 years (time)?
<u></u>
<u>Part (b)</u>
Q: How long to reach 20 g (amount remaining)?
<u></u>
