Compute the double integral D x3 ydA over the domain 1) indicated as 0 g x g 4, x 5 y 5 3x + 5. (Use symbolic notation and fractions where needed.) Incorrect Compute the double integral JJ (26xy - x2 ) dA over the region bounded below by y = x, above by y = Vx. (Use symbolic notation and fractions where needed.) (26xy - x2 ) dydx = 2.0809 IncorrectCalculate the double integral of f(x,y)= 6-896 over the triangle with vertices 0 = (0,0), A = (2,5),B = (6,5). (Use symbolic notation and fractions where needed.) Incorrect Find the volume of the region bounded by z = 168 y, z = y, y = x2, and y = 84 x2. (Use symbolic notation and fractions where needed.)
