Find the indefinite integral. (Remember to use absolute values where appropriate. Use C for the constant of integration.) dx x(l

I'm assuming the integral is

$\displaystyle \int \frac{dx}{x (\ln(x^2))^5}$

We have

$\ln(x^2) = 2 \ln|x| \implies (\ln(x^2))^5 = 32 (\ln|x|)^5$

Then substituting $y=\ln|x|$ and $dy=\frac{dx}x$ , the integral transforms and reduces to

$\displaystyle \int \frac{dx}{x(\ln(x^2))^5} = \frac1{32} \int \frac{dy}{y^5} \\\\ ~~~~~~~~ = \frac1{32} \left(-\frac1{4y^4}\right) + C \\\\ ~~~~~~~~ = -\frac1{128(\ln|x|)^4} + C$

which we can rewrite as

$128 (\ln|x|)^4 = 8\cdot2^4(\ln|x|)^4 = 8 (2\ln|x|)^4 = 8 (\ln(x^2))^4$

and so

$\displaystyle \int \frac{dx}{x (\ln(x^2))^5} = \boxed{-\frac1{8(\ln(x^2))^4} + C}$

Which pair of segments in the figures below are congruent?

oksian1 [2.3K]

Answer:

Segment B C and Segment P N

Step-by-step explanation:

we know that

Line segments are congruent if they have the same length

In this problem

we have

Segment L.M ≅ Segment F.A

Segment M.N ≅ Segment A.B

Segment P.N ≅ Segment B.C

Segment P.J ≅ Segment C.D

Segment J.K ≅ Segment E.D

Segment K.K ≅ Segment F.E

therefore

The answer is

Segment B C and Segment P N

There's one piece of information missing from the question, so
in order to completely calculate the answer, we must assume the
missing number.

We have no information that helps us calculate the probability
that you will eat the first jelly bean. So we'll have to assume that
you will definitely eat it, no matter what color it is. The probability is 1 .

-- You start out with (2 + 4 + 8 + 6) = 20 jelly beans in the package.
    8 of them are purple.

-- If you close your eyes and pull one out of the package, then the
probability that it will be purple is
      8 / 20 .

-- You definitely eat it. The probability of this event is 1 .

-- Now there are 19 jelly beans left in the package.
   6 of them are blue.

-- The probability of picking a blue one out of the package without peaking is

   6 / 19 .

-- The probability of all three of these events happening is

   (8/20) · (1) · (6/19)

   = (8 · 1 · 6) / (20 ·19)

   =    48 / 380

   = 12/95 = 0.1263... = 12.63...% (rounded)
