What is the value of x? <br> Enter your answer in the box. <br><br> (cm)

Taya2010 [7]

Answer:

x = 94 cm

Step-by-step explanation:

95.2 / 34 = 168/(x - 34)

95.2(x - 34) = 34 * 168

95.2x - 3236.8 = 5712

95.2x = 8948.8

x = 94

First change to standard form of first order linear differential equation and then by finding the appropriate integrating factor

Leokris [45]

Answer:

Step-by-step explanation:

Given is a Differential equation as

$xy' + y = lnx ; y(e)=1$

To bring it to linear form we can divide the full equation by x

$y'+\frac{y}{x} =\frac{ln x}{x}$

This is of the form

y'+p(x) *y = q(x)

p(x) = 1/x

So find

$e^{\int\limits{\frac{1}{x} } \, dx } = e^{ln x} = x$

Solution is

$xy = \int {x*lnx /x } \, dx =xln x -x +C$

Use the initial value as y(e) =1

$e= eln e -e+C\\C=e$

So solution is

$xy =xln x -x+e$
