3xy'+y=12x find general solution
Eduardwww [97]
The equation is linear, as you can write

3xy'+y=12x\implies y'+\dfrac1{3x}y=4

An integrating factor would be

\mu(x)=\exp\left(\displaystyle\int\frac{\mathrm dx}{3x}\right)=x^{1/3}

Multiplying both sides of the ODE by this yields

x^{1/3}y'+\dfrac1{3x^{2/3}}y=4x^{1/3}

where the LHS is a derivative:

\dfrac{\mathrm d}{\mathrm dx}\left[x^{1/3}y\right]=4x^{1/3}

Integrating both sides, we get

x^{1/3}y=4\displaystyle\int x^{1/3}\,\mathrm dx
x^{1/3}y=3x^{4/3}+C
y=3x^{3/3}+Cx^{-1/3}=3x+\dfrac C{x^{1/3}}

2. Find the number of cubical
lys-0071 [83]

Answer:number of boxes = 60

Volume of box = side × side × side.

 = 3 × 3 × 3

= 27 cu. cm.

Volume of carton = length × breadth × height.

= 15 × 9 × 12

= 1620 cu. cm.

Number of boxes = Volume of carton/Volume of each box.

= 1620/27

= 60

Therefore, number of boxes = 60.

Step-by-step explanation:Volume of box = side × side × side.

 = 3 × 3 × 3

= 27 cu. cm.

Volume of carton = length × breadth × height.

= 15 × 9 × 12

= 1620 cu. cm.

Number of boxes = Volume of carton/Volume of each box.

= 1620/27

= 60

Therefore, number of boxes = 60.
