IRISSAK [1]3 years ago
4 0

Answer:

47.3 grams

Step-by-step explanation:

Given: A solution contains 4.3 grams of salt per liter.

To find: Amount of salt in 11 liters of the solution

Solution:

Amount of salt in 1 liter of the solution = 4.3 grams

So, amount of salt in 11 liters of the solution = 11 × Amount of salt in 1 liter of the solution = 11 × 4.3 = 47.3 grams

Hence, 11 liters of the solution contains 47.3 grams of salt.

Step-by-step explanation: look so if you have

shcool A its 8v+4b=12

and

School B: 12v+4b= 16

since both classes used 4 busses we can use elimination by subtracting the A class Equation from the b class equation to solve from v for its value Then, use either equation and the now found value for v to solve for b.

You should find part of the process to be

12v+4b-(8v+4b)=12-16 which shows the van holds only a few people even before continuing the solution.

_________

      2       | 0

-3 | 2 a 19 3

_______<u> -3</u>

      2      | 0

-3 | 2 a 19 3

_______<u> -3</u>

      2    1 | 0

-3 | 2 a 19 3

_____<u>-18 -3</u>

     2     1 | 0

-3 | 2 a 19 3

_____<u> -18 -3</u>

     2  6  1 | 0

-3 | 2 a 19 3

_____<u> -18 -3</u>

     2  6  1 | 0

-3 | 2 a 19 3

____<u>-6 -18 -3</u>

     2  6  1 | 0

a - 6 = 6

a = 12

Find a second solution y2(x) of<br> x^2y"-3xy'+5y=0; y1=x^2cos(lnx)
rosijanka [135]

We can try reduction order and look for a solution y_2(x)=y_1(x)v(x). Then

y_2=y_1v\implies{y_2}'=y_1v'+{y_1}'v\implies{y_2}''=y_1v''+2{y_1}'v+{y_1}''v

Substituting these into the ODE gives

x^2(y_1v''+2{y_1}'v+{y_1}''v)-3x(y_1v'+{y_1}'v)+5y_1v=0

x^2y_1v''+(2x^2{y_1}'-3xy_1)v'+(x^2{y_1}''-3x{y_1}'+5y_1)v=0

x^4\cos(\ln x)v''+x^3(\cos(\ln x)-2\sin(\ln x))v'=0

which leaves us with an ODE linear in w(x)=v'(x):

x^4\cos(\ln x)w'+x^3(\cos(\ln x)-2\sin(\ln x))w=0

This ODE is separable; divide both sides by the coefficient of w'(x) and separate the variables to get

w'+\dfrac{\cos(\ln x)-2\sin(\ln x)}{x\cos(\ln x)}w=0

\dfrac{w'}w=\dfrac{2\sin(\ln x)-\cos(\ln x)}{x\cos(\ln x)}

\dfrac{\mathrm dw}w=\dfrac{2\sin(\ln x)-\cos(\ln x)}{x\cos(\ln x)}\,\mathrm dx

Integrate both sides; on the right, substitute u=\ln x so that \mathrm du=\dfrac{\mathrm dx}x.

\ln|w|=\displaystyle\int\frac{2\sin u-\cos u}{\cos u}\,\mathrm du=\int(2\tan u-1)\,\mathrm du

Now solve for w(u),

\ln|w|=-2\ln(\cos u)-u+C

w=e^{-2\ln(\cos u)-u+C}

w=Ce^{-u}\sec^2u

then for w(x),

w=Ce^{-\ln x}\sec^2(-\ln x)

w=C\dfrac{\sec^2(\ln x)}x

Solve for v(x) by integrating both sides.

v=\displaystyle C_1\int\frac{\sec^2(\ln x)}x\,\mathrm dx

Substitute u=\ln x again and solve for v(u):

v=\displaystyle C_1\int\sec^2u\,\mathrm du

v=C_1\tan u+C_2

then for v(x),

v=C_1\tan(\ln x)+C_2

So the second solution would be

y_2=x^2\cos(\ln x)(C_1\tan(\ln x)+C_2)

y_2=C_1x^2\sin(\ln x)+C_2x^2\cos(\ln x)

y_1(x) already accounts for the second term of the solution above, so we end up with

\boxed{y_2=x^2\sin(\ln x)}

as the second independent solution.
