We have two equations and two unknowns. We can eliminate if we first solve each equation for . This first step gives us two equations for . We have two expressions that both equal , so we can set them equal to each other, and then solve for : Use in either above equation to find . You should get the same answer either way so you can use both as a check. Question 14 0 / 1 pts Suppose that a certain pain medication is eliminated from the body (by metabolism) according to the model Q=150(0.70)t, where Q is the quantity of the medication in the body in milligrams (mg) and t in the time in hours since the medication was administered. How much medication was administered (include the units)? What is the hourly decay rate of the medication? Correct Answer 150 mg of medication was administered. The hourly decay rate is 30%. You Answered 150 mg of medication was administered. The hourly decay rate is 70%. 70 mg of medication was administered. The hourly decay rate is 30%.
0.70 mg of medication was administered. The hourly decay rate is 150%. 105 mg of medication was administered. The hourly decay rate is 90%. The amount of medicine administered was mg, since . The hourly decay rate is Question 15 1 / 1 pts Suppose that an investment of \$12000 has declined in value by 3% percent per year for 2 years. Choose the best expression for the value of the investment. Correct! The decay rate is , the correct exponential equation has the form where is the initial value and is the number of years.
