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}}

Factorise a.x3+4.a.x​
Contact [7]

Answer:

{ax}^{3}  + 4ax \\

factorise out a and x :

{ \boxed{answer{= ax( {x}^{2}  + 4) }}}\\ but \: farther \: more :  \\  = ax( {x}^{2}  +  {2}^{2} )

but from general factorization:

{ \boxed{( {a}^{2} +  {b}^{2}) =  {(a + b)}^{2}   - 2ab }}

a » x

b » 2

therefore:

= ax \{ {(x + 2)}^{2}  - 2(x)(2) \} \\  \\  = { \boxed{ \boxed{ax( {x + 2)}^{2} - 4x }}}

Pls list out the steps
Daniel [21]
First, the bigger square's area is 20*20= 400 cm^2

second, the circle's area is ¶r^2 = ¶(20/2)^2 = ¶(10)^2 = 100¶ cm^2

third, smaller square-- if we imagine it as 4 parts as 4 right triangles-- 1 part will be 1/2*(20/2)(20/2) = 1/2 (10)(10) = 50 cm^2 then the area of the smaller square is 4*50 = 200 cm^2

so the shaded parts = circle - smaller square =100¶ - 200 cm^2

the answer is 2

Mhanifa please help :( no one has helped me on this yet
VMariaS [17]

Answer:

16)

  • q / 12 = sin 20
  • q = 12 sin 20
  • q = 4.1
  • p / 12 = cos 20
  • p = 112 cos 20
  • p = 11.3

17)

  • x / 44 = tan 39
  • x = 44 tan 39
  • x = 35.6
  • 35.6 / y = sin 39
  • y = 35.5 / sin 39
  • y = 56.4

18)

  • 14 / b = sin 57
  • b = 14 / sin 57
  • b = 16.7
  • a / 16.7 = cos 57
  • a = 16.7 cos 57
  • a = 9.1
