- Flood Control A river is 8 feet above its flood stage. The water is receding at a rate of 3 inches per hour. Write a mathematical model that shows the number of feet above flood stage after t hours. Assuming the water continually recedes at this rate, when will the river be 1 foot above its flood stage?arrow_forwardIn 2004, a school population was 1,001. By 2008the population had grown to 1,697. Assume thepopulation is changing linearly. a. How much did the population grow between theyear 2004 and 2008? b. How long did it take the population to grow from1,001 students to 1,697 students? c. What is the average population growth per year? d. What was the population in the year 2000? e. Find an equation for the population, P, of theschool t years after 2001. f. Using your equation, predict the population of theschool in 2011 .arrow_forwardA cup of soup is left on a countertop to cool. The table below gives the temperatures, in degrees Fahrenheit, of the soup recorded over a 10-minute period. Time in Minutes (x) | Temperature in ºF (y) 0. 180.2 1658 4. 146.3 6. 135.4 8. 127.7 10 110.5 a) Graph the scatter plot on your calculator. Is the data linear, quadratic, or exponential? b) Use the appropriate regression to find the equation of best fit. c) Predict the temperature after 15 minutes. Is this interpolation or extrapolation?arrow_forward
- In July 2012, Alvarado Niles bought a house for $187,000. In September 2013, a nearby house with the same floor plan was sold for $206,000. (a) Develop a model that represents the value of the house. (Write your model in terms of t, where t is measured in months after July 2012. Round the coefficient of t to seven decimal places.) (b) Use the model to predict when the house will double its 2012 value. (Round your answer to one decimal place.) (c) Use the model to determine the value of the house one year after Mr. Niles purchased it. (Round your answer to the nearest whole number.) (d) Use part (c) to determine the rate at which the value of the house grew per month. (Round your answer to the nearest cent.)arrow_forwardIn July 2012, Alvarado Niles bought a house for $185,000.
