Answer:

12.1244 or $\sqrt{147}$

Step-by-step explanation:

Use the Pythagorean Theorem and solve for b^2:

7^2+b^2= 14^2

Simplify:

49+b^2= 196

Subtract 49 from both sides:

49-49+b^2= 196-49

Simplifly:

b^2= 147

Unsquare both sides:

$\sqrt{b} = \sqrt{147}$

Giải các phương trình vi phân sau<br> y' - y/x+1 = 2

KatRina [158]

It looks like the differential equation is

$y'-\dfrac y{x+1}=2$

Multiply both sides by 1/(<em>x</em> + 1) :

$\dfrac{y'}{x+1}-\dfrac y{(x+1)^2} = \dfrac2{x+1}$

The left side is now a derivative of a product,

$\left(\dfrac y{x+1}\right)' = \dfrac2{x+1}$

Integrate both sides with respect to <em>x</em> :

$\dfrac y{x+1} = 2\ln|x+1|+C$

Solve for <em>y</em> :

$y = 2(x+1)\ln|x+1| + C(x+1)$
