What is the integral ofintegral of (x^2)*(9- x^2)^1/2dx

WHAT IS THE DIFFERENTIAL EQUATION for tan(x^2+y^2)dy=xdx+ydy, does any body know?

what are the steps? I used the intergrating factor for the group term xdx+ydy, IF 1/(x^2+y^2). but my answer does not make sense. Anyone, please.

13 red, 13 blue, 13 yellow, and 13 green. Marbles of each color are letters A through M. 5 marbles are chosen at random. How many 5 marble choices are there? How many 5 marble choices consist of exactly 2 with the same letter and 3 others, different letters?

I had back surgery 20 years ago and I still have problems with it. I notice that it gets worse every years. I had chiropractic, physical therapy and life time exercise. I feel very unhappy and I miss out doing things I enjoy. Can anybody tell me if there is any type of solution? Any advice? Thank you.

Ammonia is a gas with a characteristic pungent odor. it is sold as a water solution for use in household cleaning. The gas is a compound of nitrogen and hydrogen in the atomic ratio 1:3. A sample of ammonia contains 7.933 g N and 1.712 g H . What is the atomic mass of N relative to H? The book answer is 13.90

13.90 what?! How? Help. Thank you.

Find the work done by F=(2xy^3)i + (4x^2y^2)j in moving a particle once counterclockwise around the curve C: the boundary of the "triangular" region in the first quadrant enclosed by the x-axis, the line x=1, and the curve y=x^3.

evaluate the triple integral of x√(y^2+4) that lies above the parabolic cylinder y^2 +4Z=16 and the planes x=0,x=1 and z=0

A plane drops a bomb. The plane fly off at 40 m/s at a height of 100 mts. Determine :

a) Where the bomb impacts the ground (horizontal distance ) relative to the initial drop.

b)The angle of depresion with the line of sight.

c) The magnitud of velocity of the bomb just before the impact.

d) The angle the bomb impact the ground.

A metal plate 3 feet long and 3 feet wide was cut in the form of letter "C" If the density of the metal plate is p = 1 lb. / ft, determine the x and y coordinates of the center (center mass when the density is constant)

Una plancha de metal de 3 pies de largo y 3 pies de ancho se corto en forma de letra "C" Si la densidad de la plancha de metal es p= 1 lb./pie, determina las coordenadas x y y del centro de (centro de masa cuando la densidad es constante)

d^2y/x^2 - 4dy/dx = 8, y= dy/dx = 0 when x =0

I know the complementary function is y A +Be^4x

I also know that particular integral y=C, since 8 is a constant.

y' = 0, y'' =0, Substituting in the original Equation C=0. I need some help.
