Evaluate the integral ∬R3xdA over the region R = {(r, θ) | 1 ≤ r ≤ 2, 0 ≤ θ ≤ π}.We're given a table of values and told that the relationship between x and y is linear. Then we're asked to find the intercepts of the corresponding graph. The key is realizing that the x -intercept is the point where y = 0 , and the y -intercept is where x = 0 . The point ( 7, 0) is our x -intercept because when y = 0 , we're on the x -axis. Rutgers coach Greg Schiano and his players know what's at stake.
