Personal Income Personal income (in billions of dollars) in the United States was 12,430 in 2008 and 14,167 in 2013. Assume that the relationship between the personal income y and the time t (in years) is linear. Let t = 0 represent 2000. (Source: U.S. Bureau of Economic Analysis)
(a) Write a linear model for the data.
(b) Estimate the personal incomes in 2011 and 2014.
(c) Use your school’s library, the Internet, or some other reference source to find the actual personal incomes in 2011 and 2014. How close were your estimates?

You are confined to use the differential identities. Let u and v be scalar fields, and F be a vector field given by F = (Vu) x (Vv) (i) Show that F is solenoidal (or incompressible). (ii) Show that G = (uvv – vVu) is a vector potential for F.arrow_forwardA driver is traveling along a straight road when a buffalo runs into the street. This driver has a reaction time of 0.75 seconds. When the driver sees the buffalo he is traveling at 44 ft/s, his car can decelerate at 2 ft/s^2 when the brakes are applied. What is the stopping distance between when the driver first saw the buffalo, to when the car stops.arrow_forwardTopic 2 Evaluate S x dx, using u-substitution.
