Replacing r 2 by x2 + y2, r cos θ by x, and r sin θ by y gives . 10. A plate has the shape of a right triangle. One leg of the triangle is 12 cm and the other is 7 cm. When the
plate is placed with one vertex at the origin, one at the point (12, 0), and one at (12, 7), the mass density (in
grams per cm2) at any point (x, y) depends only on x and is given by δ(x) = x + 2. Find the mass of the...
