Answer:
Decay
Step-by-step explanation:
Considering the model:

0.85=1-0.15
Therefore, the model can be rewritten as:

This shows that the model decays by a common ratio of 0.15 or 15%.
In general, when the common ratio is less than 1, the model decays while whenever it is greater than one, there is exponential growth.
Answer:

Answer:
Yes, it is.
Step-by-step explanation:
Although it may seem like it is not, 13/7 is a rational number. A rational number must terminate (end) or repeat. 1.8571485714... goes on forever but it repeats, making it a rational number.
