Solve the initial value problem yy′+x=x2+y2‾‾‾‾‾‾‾√ with y(1)=8‾√. To solve this, we should use the substitution u= x^2+y^2 help

leva [86]

Looks like the equation is

$yy'+x=\sqrt{x^2+y^2}$

Substitute $u(x)=x^2+y(x)^2$ , so that $u'=2x+2yy'$ . Then the equation is the same as

$\dfrac{u'-2x}2+x=\sqrt u\implies u'=2\sqrt u\implies\dfrac{\mathrm du}{2\sqrt u}=\mathrm dx$

Integrate both sides to get

$\sqrt u=C\implies\sqrt{x^2+y^2}=C$

Given that $y(1)=\sqrt8$ , we have

$\sqrt{1^2+(\sqrt8)^2}=C\implies C=3$

so the solution is

$\sqrt{x^2+y^2}=3$

Answer:

B: 1 × 10^5

Step-by-step explanation:

B is correct and C is not becasue you have to have the number multiplied by 10 to a power because then you wouldn't know what number to use as the base. I hope this helps. :)
