(a) Use a graphing utility to plot the points (h, In P). Use the regression capabilities of the graphing utility to find a linear model for the revised data points.
(b) The line in part (a) has the form In
(c) Use a graphing utility to plot the original data and graph the exponential model in part (b).
(d) Find the rates of change of the pressure when

- Cost of Adding Employees The following table shows the cost, in millions of dollars, to Walmart of adding the given number of employees to each of its superstores.14 E = number of new employees 1 2 3 4 C = cost 89.6 179.2 268.8 358.4 a. Find a linear model for the data in the table. b. Explain in practical terms the meaning of the slope of the linear model you found in part a.arrow_forwardLyme Disease The numbers Nof confirmed cases of Lyme disease in Maryland from 2007 through 2014 are shown in the table, where t represents the year, with t=7corresponding to 2007. (a) Use a graphing utility to create a scatter plot of the data. (b) Use the regression feature of the graphing utility to find a quartic model for the data. (A quartic model has the form at4+bt3+ct2+dt+e,where a,b,c,d,and e are constant and t is variable.) Graph the model in the same viewing window as the scatter plot. (c) Use the model to create a table of estimated values of N.Compare the model with the original data. (d) Use synthetic division to confirm algebraically your estimated value for the year 2014.arrow_forwardCellular Phone Subscribers The table shows the numbers of cellular phone subscribers y in millions in the United States from 2008 through 2013. Source: CTIA- The Wireless Association Year200820092010201120122013Number,y270286296316326336 (a) Find the least squares regression line for the data. Let x represent the year, with x=8 corresponding to 2008. (b) Use the linear regression capabilities of a graphing utility to find a linear model for the data. How does this model compare with the model obtained in part a? (c) Use the linear model to create a table of estimated values for y. Compare the estimated values with the actual data.arrow_forward
