Now here is the problem:
Given: y = 9 - x^2, y = 2
Find the coordinates of the centroid of the above plane region.
Please refer to the attached file as well for extra information.
f(x) = 9-x^2 = y; g(x) = 2 = y
1. Find the points of intersections of these two curves.
9-x^2 = 2 -> x^2 = 7 -> x = +/- sqrt(7); y = 2
Since the f(x)-g(x)area is below the parabola f(x), but above the line, y =2 is the ...
