Solve the given initial-value problem. the de is a bernoulli equation. x2 dy dx − 2xy = 4y4, y(1) = 1 2

mario62 [17]

$x^2\dfrac{\mathrm dy}{\mathrm dx}-2xy=4y^4$
$x^2y^{-4}\dfrac{\mathrm dy}{\mathrm dx}-2xy^{-3}=4$

Substitute $z=y^{-3}$ , so that $\dfrac{\mathrm dz}{\mathrm dx}=-3y^{-4}\dfrac{\mathrm dy}{\mathrm dx}$ . Then the ODE in terms of $z(x)$ is

$-\dfrac13x^2\dfrac{\mathrm dz}{\mathrm dx}-2xz=4$
$x^2\dfrac{\mathrm dz}{\mathrm dx}+6xz=-12$
$x^6\dfrac{\mathrm dz}{\mathrm dx}+6x^5z=-12x^4$

$\dfrac{\mathrm d}{\mathrm dx}\left[x^6z\right]=-12x^4$
$\implies x^6z=-\dfrac{12}5x^5+C$
$\implies z=-\dfrac{12}{5x}+\dfrac C{x^6}$
$\implies\dfrac1{y^3}=-\dfrac{12}{5x}+\dfrac C{x^6}$

and you can attempt to solve for $y$ explicitly from here if you wish.
In any case, given that $y(1)=\dfrac12$ (presumably that's what you meant to write), we'd get

$\dfrac1{\left(\frac12\right)^3}=-\dfrac{12}{5\cdot1}+\dfrac C{1^6}$
$8=-\dfrac{12}5+C\implies C=\dfrac{52}5$

giving a particular solution of

$\dfrac1{y^3}=-\dfrac{12}{5x}+\dfrac{52}{5x^6}$

In a right triangle, one of the angles measures 29º. What is the measure of the

serious [3.7K]

Answer:

90° and 61°

Step-by-step explanation:

Since it's a right angled triangle, I thought it was wrong since you said right angle.

180 - 29 = 151

There is always one right angle in a right angled triangle, which is 90°, so you just have to deduct 90° and 29° from 180° and you will find out the answer.

180 - 29 - 90 = 61°
