In 1950, the life-expectancy of women was 72 years old. In 1970, it was 75 years. Let E represents the life expectancy and "t" the number of years since 1950 (t = 0 gives 1950 and t = 10 gives 1960). 21. Express a linear function of life expectancy of women to the data points (0, 72) and (20, 75). a. E=3t-72 c. E=3t/20 + 72 b. E= 20t+72 d. E=3t+72 22. Predict the life expectancy of women in 2003. a. 79.95yrs old b. 81.25yrs. old 23. Predict the life expectancy of women in 2018. a. 71.25yrs. old b. 75.5yrs old c. 82.35yrs. old d. 83.25yrs old c. 82.2yrs old d. 88.6yrs old

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?
