Karla took a 400 mg dose of antibiotics. Her doctor said that the amount of medicine in her bloodstream would change by 23% per hour. What is the 1-hour growth (or decay) factor for the amount of medicine in Karla's bloodstream? Preview Write a formula for the function that models the amount of medicine in Karla's bloodstream (in mg) in terms of the number of hours since she took the dose. Be sure to use function notation. Preview Evaluate and interpret f(3). f(3) Preview This value represents the number of (Select an answer). d. Modify your function formula from part (b) if her initial dose was 600 mg instead of 400 mg and if the hourly percent change was 37%. Preview

Step 1
The 1-hour growth (or decay) factor for the amount of medicine in Karla's bloodstream is 1 + 0.23 = 1.23. So, the 1-hour growth factor is $\boxed{1.23}$. Show more…

The patient has taken an initial dose of prescription medication. The relationship between the elapsed time t, in hours since they took the first dose, and the amount of medication, M(t), in milligrams (mg) in their bloodstream is modeled by the following function: M(t) = 70e^(-0.6t) Round your answers to 1 decimal place and include the correct units. a) How much medication is in their bloodstream at 3 hours? b) At what rate is the medication in their bloodstream decreasing after 3 hours? (Note: Do not enter a negative number because we already used the word "decreasing.")

A patient is given a 300mg dose of medicine that degrades by 25% every hour. a. Write a function to describe this situation. Identify the units of each value and write a sentence explaining what each piece of the function represents in this context. b. What is the remaining drug concentration after a day? c. Use Guess and Check to determine about how many hours will it take for the drug concentration to be halved. Find an estimated value to the nearest half hour. We want our function to output: ________ Because ______________________________________________________ d. Use Guess and Check to determine about how many hours will it take for the drug concentration reach 5mg. Find an estimated value to the nearest half hour.

A certain drug is eliminated from the bloodstream with a half-life of 32 hours. Suppose that a patient receives an initial dose of 40 mg of the drug at midnight. a. How much of the drug is in the patient's blood at noon later that day? b. When will the drug concentration reach 50% of its initial level? a. The reference point is midnight. If t is measured in hours, what is the exponential decay function? y(t) = (Type an expression. Do not round until the final answer. Then round coefficients to six decimal places as needed.)
