Water boils at 212°F at sea level and at 193.6°F at an altitude of 10,000 feet. (a) Find a relationship of the form T = mx + b where T is degrees Fahrenheit and x is altitude in thousands of feet. (b) Find the boiling point at an altitude of 4,300 feet. (c) Find the altitude if the boiling point is 197.5°F. (d) Graph T and illustrate the answers to (b) and (c) on the graph. (a) Choose the correct relationship below. O A. T = 1.84x+212 O B. T = 1.84x +212 O C. T = 1.84x-212 O D. T= 1.84x - 212arrow_forward

- U.S. Airplane Passenger Projections In a report issued by the U.S. Department of Transportation in 2012, it was predicted that the number of passengers boarding planes in the United States would grow steadily from the current 0.7 billion boardings/year to 1.2 billion boardings/year in 2032. Find a linear function f giving the projected boardings (in billions) in year t , where t =0 corresponds to 2012. What is the projected annual rate of growth of boardings between 2012 and 2032? How many boardings per year are projected for 2022?arrow_forwardA coffee shop currently sells 470 lattes a day at $3.50 each. They recently tried raising the by price by $0.25 a latte, and found that they sold 50 less lattes a day. a) Assume that the number of lattes they sell in a day, N, is linearly related to the sale price, 'p' (in dollars). Find an equation for N as a function of p. N(p) = b) Revenue (the amount of money the store brings in before costs) can be found by multiplying the cost per cup times the number of cups sold. Again using p as the sales price, use your equation from above to write an equation for the revenue, R as a function of p.
