Please help I’m lost it has to be 3 or 2 or more answers by the way and I will except answers from Expert, Ace, or Genius or any

deff fn [24]

The correct answer is only A, because you need the tenths place to be greater than the number on the left, and not just the hundredths place.

P.S. Even though I'm a beginner, I took Multi-Variable calculus in 12th grade.
P.P.S. STOP PUTTING ON RANDOM ANSWERS ON QUESTIONS JUST SO YOU CAN GET THE POINTS!!!!!!

Find the general solution of the given differential equation. x dy dx − y = x2 sin(x) y(x) = Correct: Your answer is correct. Gi

Divide both sides by $x^2$ - note that this means we can't have $x=0$ :

$x\dfrac{\mathrm dy}{\mathrm dx}-y=x^2\sin x$

$\dfrac1x\dfrac{\mathrm dy}{\mathrm dx}-\dfrac1{x^2}y=\sin x$

Then the left side reduces to the derivative of a product,

$\dfrac{\mathrm d}{\mathrm dx}\left[\dfrac1xy\right]=\sin x$

$\dfrac1xy=\displaystyle\sin x\,\mathrm dx=\cos x+C$

$y=x\cos x+Cx$

This solution is continuous everywhere, but accounting for the singular point $x=0$ , the largest interval over which it is defined would be $(0,\infty)$ or $(-\infty,0)$ .
