Insulin comes in 10 cubic centimeter (cc) vials labeled in the number of units of insulin per cubic centimeter of fluid. A vial marked U40 has 40 units of insulin per cubic centimeter of fluid. If a patient needs 14 units of insulin, how much fluid should be drawn into the syringe from the U40 vial? The amount of fluid containing 14 units of insulin is [ ] cc. (Type an integer or a decimal.)

Step 1
We need to find out how much fluid contains 14 units of insulin. We can set up a proportion to solve this: 40 units : 1 cc = 14 units : x cc Cross-multiplying gives us 40x = 14, So, x = 14/40 = 0.35 cubic centimeters. Show more…

Blood Sugar Level Insulin affects the glucose, or blood sugar, level of some diabetics according to the function $G(x)=-0.2 x^{2}+450$, where $G(x)$ is the blood sugar level 1 hour after $x$ units of insulin are injected. (This mathematical model is only approximate, and it is valid only for values of $x$ less than about $40 .$ Find the blood sugar level after the following numbers of units of insulin are iniected. (a) 0 (b) 25 Find the rate of change of blood sugar level after injection of the following numbers of units of insulin. $\begin{array}{ll}{\text { (c) 10 (d) 25

A drug is administered intravenously to a patient at the rate of 14 mg/h. The patient's body eliminates the drug over time so that after t hours the proportion that remains is e^?0.25t. If the patient currently has 80 mg of the drug in her bloodstream, how much of the drug is present 8 hours from now? (Round your answer to one decimal place.)
