Question 149929: Exponential and Logarithmic Functions
Like always reading and translating these are tough. Thank you for helping
Problem: The level of a prescription drug in the human body over time can be found using the formula:
where D is the amount taken every n hours and H is the drug�s half-life in hours.
1.If 2.5 milligrams of Lorazepam with a half-life of 14 hours is taken every 24 hours, then to what level does the drug build up over time?
2.If a doctor wants the level of Lorazepam to build up to a level of 5.58 milligrams in a patient taking 2.5 milligram doses, then how often should the doses be taken?
3.What is the difference between taking 2.5 milligrams of Lorazepam every 12 hours and taking 5 milligrams every 24 hours?
4. What mathematical concepts are applyied and explain the steps in order to solve this problem
Thank you
