After a certain medicine is ingested, its concentration in the bloodstream changes over time.
2 answers:
Answer:
Every hour, the medicine concentration decays by a factor of 4%.
Step-by-step explanation:
The relationship between the elapsed time, <em>t</em>, in minutes, since the medicine was ingested, and its concentration in the bloodstream, <em>C</em> (<em>t</em>), is:
The decay function is:
Here,
<em>y</em> = final amount
<em>a </em>= initial amount
<em>r</em> = decay rate
<em>t</em> = time
From the provided expression the decay rate is:
Thus, every hour, the medicine concentration decays by a factor of 4%.

Step-by-step explanation:
A geometric sequence goes from one term to the next by always multiplying or dividing by the same value.
In geometric sequences, the ratio between consecutive terms is always the same. We call that ratio the common ratio.
This is the explicit formula for the geometric sequence whose first term is <em>k</em> and common ratio is<em> r:</em>
<em> </em><em />
This is the recursive formula of that sequence:
We know that the first term is <em>k</em> = 3 and the common ratio is <em>r = </em>2. Therefore,
The explicit formula is and the recursive formula is
