What the duck is the freaking answer too 1/12=x/80

ASHA 777 [7]

If you are setting it up as a proportion then you would muiltiply the 12 and x to get 12x. Then muiltiply the 80 and 1 to get 80. So 12x=80. Divide the 12 to get your final answer

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

$xy =xln x -x+e$

What is the value of n in this equation: 2↑2 * 2↑n = (2↑4)↑3

Cloud [144]

Answer:

The value of n in the given equation is; n = 10

Step-by-step explanation:

Exponent for a natural power b is defined as iterated multiplication, which Knuth denoted by a single up-arrow:

a↑b = $a^b$ ......[1]

Given the expression: 2↑2 * 2↑n = (2↑4)↑3

Using [1] in the given expression is;

$(2^2) \cdot 2^n = (2^4)^3$

Using $a^n \cdot a^m = a^{n+m}$ and $(a^n)^m = a^{nm}$

we have;

$2^{2+n} = 2^{12}$

2 + n = 12 [ Using $a^m = a^n$ ⇒ m =n ]

Subtract 2 to both sides of an equation:

2 + n - 2 = 12 -2

Simplify:

n = 10

Therefore, the value of n is, 10
