A company produces a product for which the variable cost is $12.39 per unit and the fixed costs are $96,000. The product sells for $17.30. Let x be the number (a) The total cost for a business is the sum of the variable cost and the fixed costs. Write the total Cost C as a function of the number of units produced. C = (b) Write the revenue R as a function of the number of units sold. R = (c) Write the profit P as a function of the number of units sold. (Note: P = R - C.) P =

HN) Exercises (1)You take 200 milligrams of a headache medicine, and after 4 hours, 120 milligrams remain in your system. If the effects of the medicine wear off when less than 80 milligrams remain, when will you need to take a second dose, assuming the anmount of medicine in your system decays exponentially? 13 ส.ค. The half-life of Radium-226 is 1590 years. If a sample initially contains 200 mg. how many milligrams will remain after 1000 years? )The half-life of Fermium-253 is 3 days. If a sample initially contains 100 mg, how many milligrams will remain after 1 week? บ้อ The half-life of Erbium-165 is 10.4 hours. After 24 hours a sample still contains 2 mg. What was the initial mass of the sample, and how much will remain after another 3 days? The half-life of Nobelium-259 is 58 minutes. After 3 hours a sample still contains10 mg. What was the initial mass of the sample, and how much will remain after another 8 hours? (6) A scientist begins with 250 grams of a radioactive substance. After 225 minutes, the sample has decayed to 32 grams. Find the half-life of this substance. A wooden artifact from an archeological dig contains 60 percent of the carbon-14 that is present in living trees. How long ago was the artifact made? (The half-life of carbon-14 is 5730 years.)
