Chapter 2.4, Problem 25E
In Exercises 25-26, find a linear function in slope-intercept form that models the given description. Each function should model the percentage of total spending, p(x), by Americans x years after 1950.
In 1950, Americans spent 22% of their budget on food. This has decreased at an average rate of approximately 0.25% per year since then.

A Webmaster has tracked an increasing number of registered users since the beginning of an advertising campaign. Before starting to advertise, he had 2,200 registered users and after 4 months of advertising he now has 5,480 registered users. Use this data to write a linear function that gives the total number of registered users, given the number of months after starting to advertise. Use the function to predict the number of registered users 8 months into the advertising campaign.
Between 2000 and 2010, the use of opioids was
exploding in the USA. We use MME (Morphine Milligram
Equivalents) as a measure of doses used. It went from
85.3 billion doses in 2000 to a level 164% higher in 2009.
Assuming a linear trend (billion of doses as a function of
years t), what is the vertical intercept of the linear
function of the use of opioids, in billion? Assume that t=0
in 2003.
If needed, round your answer to 2 digits after the decimal
point.
Answer:
The growth rate of the speed of sound in relation to the temperature in degrees Fahrenheit is a linear function. The speed of sound at 0 degrees Fahrenheit is 1052.3 feet per second. For every 1 degree Fahrenheit rise in temperature, the speed of sound increases by 1.1 feet per second.
A. Identify the initial value of linear function that gives the speed of sound in terms of temperature.
B. A 20 degree Fahrenheit rise in temperature would provide what increase in the speed of sound?
C. What would the speed of sound be after a 67 degree Fahrenheit rise in temperature?
