What should thef-stop setting be?arrow_forwardIn Example 7, find the average speed of the car (a) from t1=0tot2=1 second and (b) from t1=1 second to t2=4 seconds.arrow_forwardFor the following exercises, consider this scenario: The population of a city increased steadily over a ten-year span. The following ordered pairs show the population and the year over the ten-year span (population, year) for specific recorded years: Predict when the population will hit 12,000.arrow_forward
- For the following exercises, consider this scenario: The population of a city increased steadily overa ten-year span. The following ordered pairs show the population and the year over the ten-year span (population, year) for specific recorded years: (3,600,2000);(4,000,2001);(4,700,2003);(6,000,2006) 45. According to the model, what is the populationin 2014?arrow_forwardUsing the data in Example 12, how much radon-222 will remain after one year?arrow_forwardFor the following exercises, consider this scenario: The profit of a company decreased steadily over a ten-year span.The following ordered pairs show dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span (number of units sold, profit) for specific recorded years: (46,250),(48,305),(50,350),(52,390),(54,410). Predict when the profit will dip below the $25,000threshold.arrow_forward
- For the following exercises, consider this scenario: The profit of a company decreased steadily overa ten-year span.The following ordered pairs show dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span (number of units sold, profit) for specific recorded years: (46,250),(48,305),(50,350),(52,390),(54,410). Use linear regression to determine a function y,where the profit in thousands of dollars depends onthe number of units sold in hundreds.arrow_forwardFor the following exercises, consider this scenario: The profit of a company increased steadily over a ten-year span.
