Can you show the image of the problem wanting to be solved for extra support and I would know how to solve this or is this all
14 and 15 are both choice B
Answer:
a.
b.
Step-by-step explanation:
First, we need tot find a general expression for the amount of caffeine remaining in the body after certain time. As the problem states that every hour x percent of caffeine leaves the body, we must substract that percentage from the initial quantity of caffeine, by each hour passing. That expression would be:
Then, to find the amount of caffeine metabolized per hour, we need to differentiate the previous equation. Following the differentiation rules we get:
The rate is negative as it represents the amount of caffeine leaving the body at certain time.
The answer is D -2x^3-16x^2-10x
