- Running Ants A scientist observed that the speed S at which certain ants ran was a function of T, the ambient temperature. He discovered the formula S=0.2T-2.7, Where S is measured in centimetres per second and T is in degrees Celsius. a. Using functional notation, express the speed of the ants when the ambient temperature is 30 degrees Celsius, and calculate that speed using the formula above. b. Solve for T in the formula above to obtain a formula expressing the ambient temperature T as a function of the speed S at which the ants run. c. If the ants are running at a speed of 3 centimeters per second, what is the ambient temperature?arrow_forwardTax Owed According to the Oklahoma Income Tax Table for 2010, the income tax owed by an Oklahoma resident who is married and filing jointly with a taxable income above 100, 000 is 5070 plus 5.5 of the taxable income over 100, 000. a. Use a formula to express the tax owed as a function of the taxable income, assuming that the taxable income is above 100, 000. Be sure to explain the meaning of the letters you choose and the units. b. What is the tax on a taxable income of 108, 650? Round your answer to the nearest dollar. c. For what taxable income would the tax be 5686?arrow_forwardLater Public High School Enrollment Here is a model for the number of students enrolled in U.S. public high schools as a function of time since 2000. N=0.033t2+0.46t+13.37 In this formula, N is the enrollment in millions of students, t is the time in years since 2000, and the model is applicable from 2000 to 2010. a. Calculate N(10) and explain in practical terms what it means. b. In what year was the enrollment the largest? c. Find the average yearly rate of change in enrollment from 2004 to 2010. Is the result misleading, considering your answer to part b?arrow_forward
- Juice Sales The number J, in thousands, of cans of frozen orange juice sold weekly is a function of the price P, in dollars, of a can. In a certain grocery store, the formula is J=11-2.5P. a. Express using functional notation the number of cans sold weekly if the price of a can is 1.40, and then calculate that value. b. At what price will there be 7.25 thousand cans sold weekly? c. Solve for P in the formula above to obtain a formula expressing P as a fuction of J. d. At what price will there be 7.75 thousand cans sold weekly?arrow_forwardGrowth in Weight and Height Between the ages of 7 and 11 years, the weight w, in pounds, of a certain girl is given by the formula w=8t. Here t represents her age in years. a. Use a formula to express the age t of the girl as a function of her weight w. b. At what age does she attain a weight of 68 pounds? c. The height h, in inches, of this girl during the same period is given by the formula h=1.8t+40. i. Use you answer to part b to determine how tall she is when she weighs 68 pounds. ii. Use a formula to express the height h of the girl as a function of her weight w. iii. Answer the question in part i again, this time using your answer to part ii.arrow_forwardTemperature Conversions In everyday experience, the measure of temperature most often used are Fahrenheit F and Celsius C. Recall that the relationship between them is given by F=1.8C+32. Physicists and chemists often use the Kelvin temperature scale. You can get kelvinsK from degrees Celsius by using K=C+273.15. a. Explain in practical terms what K30 means, and then calculate that value. b. Find a formula expressing the temperature C in degrees Celsius as a function of the temperature K in kelvins. c. Find a formula expressing the temperature F in degrees Fahrenheit as a function of the temperature K in kelvins. d. What is the temperature in degrees Fahrenheit of an object that is 310 kelvins?arrow_forward
- m Miles per Gallon The cost of operating a car depends on the gas mileage in that your car gets, the cost x per gallon of gasoline, and the distance d that you drive. a. How much does it cost to drive 100 miles if your car gets 25 miles per gallon and gasoline costs 349 cents per gallon? b. Find a formula that gives the cost C as a function of m, g, and d be sure to state the units of each variable. c. Use functional notation to show the cost of driving a car that gets 28 miles per gallon a distance of 138 miles if gasoline costs 3.69 per gallon Use the formula from part b to calculate the cost.arrow_forwardAverage Speed: A commuter regularly drives 70 miles from home to work, and the amount of time required for the trip varies widely as a result of road and traffic conditions. The average speed for such a trip is a function of the time required. For example, if the trip takes 2 hours, then the average speed is 70/2 = 35 miles per hour. a. What is the average speed if the trip takes an hour and a half? b. Find a formula for the average speed as a function of the time required for the trip. You need to choose variable and function names. Be sure to state units. c. Make a graph of the average speed as a function of the time required. Includes trips from 1 hour to 3 hours in length. d. Is the graph concave up or concave down? Explain in practical terms what this meansarrow_forwardA forest fire leaves behind an area of grass burned in an expanding circular pattern.

- Growth in Length of Haddock D.S. Raitt found that the length L of haddock in centimeters as a function of the age t in years is given approximately by the formula L=5342.820.82t a. Calculate L(4) and explain what it means. b. Compare the average yearly rate of growth in length from age 5 to age 10 years with the average yearly rate of growth from age 15 to age 20 years. Explain in practical terms what this tells you about the way haddock grow. c. What is the longest haddock you would expect to find anywhere?arrow_forwardFlood Control A river is 8 feet above its flood stage. The water is receding at a rate of 3 inches per hour. Write a mathematical model that shows the number of feet above flood stage after t hours. Assuming the water continually recedes at this rate, when will the river be 1 foot above its flood stage?arrow_forward
