Solve the Differential equation 2(y-4x^2) dx + x dy = 0
padilas [110]

Assume a solution of the form \Psi(x,y)=C. Taking the differential of both sides would give the ODE

\Psi_x\,\mathrm dx+\Psi_y\,\mathrm dy=0

where \Psi_x=2y-8x^2 and \Psi_y=x. The ODE is exact if \Psi_{xy}=\Psi_{yx}. We have

\Psi_{xy}=(2y-8x^2)_y=2

\Psi_{yx}=(x)_x=1

so the ODE is not exact. However, multiplying both sides by x gives

(2xy-8x^3)\,\mathrm dx+x^2\,\mathrm dy=0

and now

(x\Psi_x)_y=(2xy-8x^3)_y=2x

(x\Psi_y)_x=(x^2)_x=2x

so the ODE is now exact.

Now,

\Psi_x=2xy-8x^3\implies \Psi(x,y)=x^2y-2x^4+f(y)

\Psi_y=x^2=x^2+f_y\implies f_y=0\implies f(y)=C

So the ODE has solution

\Psi(x,y)=x^2y-2x^4+C=C

or simply

\boxed{x^2y-2x^4=C}

Enrique can spend at most $2240 to renovate his home. One roll of wallpaper costs $32, and one can of paint costs $28. He needs
umka2103 [35]

The possible solution is having 30 rolls of wallpaper and 20 can of paints or 30 rolls of wallpaper with 46 can of paint.

<h3>Inequality</h3>

Inequality is the non equal comparison of two or more numbers and variables.

Let x represent the number of wallpapers and y represent the number of cans.

He needs at least 30 rolls of wallpaper and at least 20 cans of paint. Hence:

x ≥ 30   (1);

y ≥ 20    (2)

Also:

32x + 28y ≤ 2240    (3)

Plotting the 3 equations using geogebra online graphing tool, the possible solution is:

(30, 20), (30, 46)

The possible solution is having 30 rolls of wallpaper and 20 can of paints or 30 rolls of wallpaper with 46 can of paint.
