How much did the population grow between the year 2004 and 2008? b. How long did it take the population to grow from 1001 students to 1697 students? c. What is the average population growth per year? d. What was the population in the year 2000? c. Find an equation for the population, P, of the school t years after 2000. f. Using your equation, predict the population of the school in 2011. 2. A phone company has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 410 minutes, the monthly cost will be $71.50. If the customer uses 720 minutes, the monthly cost will be $1 18. a. Find a linear equation for the monthly cost of the cell plan as a function of x, the number of monthly minutes used. b. Interpret the slope and vertical intercept of the equation. c. Use your equation to find the total monthly cost if 687 minutes are used.3. In 1991, the moose population in a park was measured to be 4360. By 1999, the population was measured again to be 5880. If the population continues to change linearly, a. Find a formula for the moose population, P. b. What does your model predict the moose population to be in 2003? 4. You are choosing between two different prepaid cell phone plans. The first plan charges a rate of 26 cents per minute. The second plan charges a monthly fee of $19.95 plus 11 cents per minute. How many minutes would you have to use in a month in order for the second plan to be preferable?5. Find the area of a triangle bounded by the y axis, the line f (x) =9--x, and the line perpendicular to f(x) that passes through the origin. W6. Find the area of a parallelogram bounded by the y axis, the line x =3, the line f (x) =1+2x, and the line parallel to f(x) passing through (2, 7) 7. The median home values in Mississippi and Hawaii (adjusted for inflation) are shown below. If we assume that the house values are changing linearly, Year Mississippi Hawaii 1950 25200 74400 2000 71400 272700 a. In which state have home values increased at a higher rate? b. If these trends were to continue, what would be the median home value in Mississippi in 2010? C. If we assume the linear trend existed before 1950 and continues after 2000, the two states' median house values will be (or were) equal in what year?
