- Software Publishing The table shows the estimate revenues in billions of dollars of software publishers in the United States from 2011 through 2013.Source: U.S. Census Bureau Year Revenues, y 2011 156.8 2012 161.7 2013 177.2 a Create a system of linear equations for the data to fit the curve y=at2+bt+c Where t = 1 corresponds to 2011, and y is the revenue. b Use Cramers Rule to solve the system. c Use a graphing utility to plot the data and graph the polynomial function in the same viewing window. d Briefly describe how well the polynomial function fits the data.arrow_forwardTemperature In Exercises 29 and 30, the figure shows the boundary temperatures in degree Celsius of an insulted thin metal plate. The steady-state temperature at an interior junction is approximately equal to the mean of the temperatures at the four surrounding junctions. Use a system of linear equations to approximate the interior temperatures T1,T2,T3, and T4.arrow_forwardInternational Travel: The table shows the numbers of visitors y (in thousands) to the United States from China from 2012 through 2014. (a) The data can be modeled by the quadratic function y=at2+bt+c. Write a system of linear equations for the data. Let t represent the year, with t=12 corresponding to 2012. (b) Use the matrix capabilities of a graphing utility to find the inverse of the coefficient matrix of the system from part (a). (c) Use the result of part (b) to solve the system and write the model y=at2+bt+c. (d) Use the graphing utility to graph the model with the data.arrow_forward
