How many integers appear in both of the following arithmetic progressions: A1: 2, 9, 16,.....2+(1000-1)*7 A2: 3, 12, 21,.....3+(1000-1)*9 Since 2 appears in A1 but not in A2, it does not appear in both of the arithmetic progressions.

a) Assuming you meant x^3 + y^3 - x y^2 = 5 3x^2 + 3y^2 dy/dx - x(2y)dy/dx - y^2 = 0 dy/dx(3y^2 - 2xy) = y^2 - 3x^2 dy/dx = (y^2 - 3x^2)/(3y^2 - 2xy) b) just arithmetic, you do it c) yours d) for a horizontal tangent, dy/dx = 0 then y^2 - 3x^2 = 0 y^2 = 3x^2 y = ± x&#...

No top ? So I see a base which is (50-2x) by (40-2x) and I see a height of x total surface area = (50-2x)(40-2x) + 2x(50-2x) + 2x(40-2x) =2000 - 180x + 4x^2 + 100x - 4x^2 + 80x - 4x^2 = -4x^2 + 2000 -4x^2 + 2000 = 1900 -4x^2 = -100 x^2 = 25 x = √25 = 5 check my arithmetic
