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?
The demand for gasoline can be modeled as a linear function of price. If the price of gasoline is p = $3.10 per gallon, the quantity demanded in a fixed period is q = 75 gallons. If the price rises to $3.50 per gallon, the quantity demanded falls to 45 gallons in that period. (a) Find a formula for q in terms of p. Oq = – 75p + 307.5 q = – 307.5p + 75 Oq = 75p – 157.5 q = – 75p – 157.5 Oq = 75p + 307.5

C. What is the estimated weight of a 3 year old child?
The owner of a local hair salon is planning to raise the price for a haircut and blow dry. The current rate is $30 for this service, with the salon averaging 550 clients a month. A survey indicates that the salon will lose 5 clients for every incremenetal price increase of $2.50. a. Write an equation to model the salon’s monthly revenue, R, in dollars, as a function of x, where x represents the number of $2.50 increases in price. b. Use the product rule to determine R’(x). c. Solve for R’(x) = 0.
