SOLUTION
The question simply means that we should find the sum to infinity of the geometric series.
The formula of sum to infinity of a geometric serie is given by
Where
So, this becomes
Therefore, option b is the correct answer
Given:
The initial mass of an element is 800 grams.
Decay rate = 8.2% per day
Number of days = 15
To find:
The remaining element after 15 days.
Solution:
The exponential decay model is
Where, a is the initial value r is the rate of interest and t is time period.
Putting in the above formula, we get
Therefore, the mass of the remaining element is 221.7 grams.
Answer:
I think this is the correct answer
