Later 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?
Titanic At 2:00 p.m. on April 11, 1912, the Titanic left Cobh, Ireland, on her voyage to New York City. At 11:40 p.m. on April 14, the Titanic struck an iceberg and sank, having covered only about 2100 miles of the approximately 3400-mile trip. (a) What was the total duration of the voyage in hours? (b) What was the average speed in miles per hour? (c) Write a function relating the distance of the Titanic from New York City and the number of hours traveled. Find the domain and range of the function. (d) Graph the function in part (c).
TEST YOUR UNDERSTADING FOR EXAMPLE 3.5 A donation to the university is required for the privilege of purchasing premium season football passes. The cost is a linear function of the number of season passes. It costs 8000 to get season passes for myself and my spouse. To get passes for my entire family of 5, it costs 17,000. Use a formula to express the total cost C, in dollars, of n season passes. EXAMPLE 3.5 CHANGING CELSIUS TO FAHRENHEIT Temperature F=F(C) in Fahrenheit is a linear function of the temperature C in Celsius. A lab assistant placed a Fahrenheit thermometer beside a Celsius thermometer and observed the following: When the Celsius thermometer reads 30 degree (C=30), the Fahrenheit thermometer reads 86 degrees (F=86). When the Celsius thermometer reads 40 degrees, the Fahrenheit thermometer reads 104 degrees. Part 1 Use a formula to express F as a linear function of C. Part 2 At sea level, water boils at 212 degrees Fahrenheit. What temperature in degrees Celsius makes water boil? Part 3 Explain in practical terms what the slope means in this setting.
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?
Temperature 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?
