Find the general solution to 1/x dy/dx - 2y/x^2 = x cos x, y(pi) = pi^2

Step-by-step explanation:

Consider linear differential equation

It's solution is of form where I.F is integrating factor given by .

Given:

We can write this equation as

On comparing this equation with , we get

I.F =      { formula used: }

we get solution as follows:

{ formula used: }

Applying condition:

So, we get solution as :

42

step-by-step explanation:

256/6=42

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
