How do you right a number in its prime factorization?

Please use "write" here, not "right." "write" is "right" here, if you get my drift.
"right" is wrong in this context.    ;)

Example:  Most of us would see immediately that 5 is a prime factor of 50.

Write 50 as 5 * 10.

10 is not prime; it can be factored into 5 and 2.

Thus, 50 written as the product of its prime factors is 5 * 5 * 2  (answer)

The function g has an inverse. The function g − 1 determines the number of folds needed to give the folded paper a thickness of
Amanda [17]

Answer:

\mathbf{g^{-1} (t) = log _2  \ 20 \ t}

Step-by-step explanation:

Here is the full question

A standard piece of paper is 0.05 mm thick. Let's imagine taking a piece of paper and folding the paper in half multiple times. We'll assume we can make "perfect folds," where each fold makes the folded paper exactly twice as thick as before - and we can make as many folds as we want.

Write a function g that determines the thickness of the folded paper (in mm) in terms of the number folds made, n. (Notice that g(0) 0.05,)

g(n )= (05)2^n

The function g has an inverse. The function g⁻¹ determines the number of folds needed to give the folded paper a thickness of t mm. Write a function formula for g⁻¹).

<u>SOLUTION:</u>

If we represent g(n) with  t;

Then

\mathbf{t = (0.05)2^n} \\ \\ \mathbf{\dfrac{t}{0.05} = 2^n} \\ \\ \mathbf{\dfrac {100 \ t }{ 5} = 2^n} \\  \\ \mathbf{20 t = 2^n}

Taking logarithm of both sides; we have :

\mathbf{log (20 t) = n log 2}    \ \ \    \mathbf{(since  \ ,  log  \ a^b = b \ log \ a) }  \\ \\ \mathbf{n =  \dfrac{log \ 20 t }{log \ 2 }} \\ \\ \mathbf{g^{-1} (t) =  \dfrac{log \ 20 t }{log \ 2 }} \\ \\ \mathbf{g^{-1} (t) = log _2  \ 20 \ t}

A book can be classified as either non dash fiction or fiction. Suppose that 87​% of books are classified as fiction. ​(a) Two b
Mnenie [13.5K]

Answer:

0.7569, 0.5729,0.4371

Step-by-step explanation:

Given that the books are of only two types either non dash fiction or fiction.

Also probability of selecting a fiction = 0.87 = p

X - no of books fiction selected is binomial with p = 0.87 and n =2

(since each trial is independent of the other and there are only two trials)

a) the probability that both books are fiction=

P(X=2) = 0.87^2 = \\0.7569

b) Here n =4 with same p.

P(X=4) =0.87^4 \\= 0.5729

c) Prob atleast one is non dash  fiction =P(X< 4)\\= 1-P(X=4)\\=1-0.87^4\\=0.4371

This is not unusual since 0.4371 probability is not nearer to 0 it is almost half.

For the parallelogram, if m&lt;2=4x-17 and m&lt;4=3x-8, find m&lt;1.
kompoz [17]

Answer:

D. 161°

Step-by-step explanation:

m<2 is congruent to m<4, m<1 is congruent to m<3 by properties of a parallelogram

to find x:

4x-17=3x-8

x-17=-8

x=9

m<4=3(9)-8=19

so, m<4=19°

m<2 =19°

to find m<1:

the interior angles of a parallelogram add up to 360°

360-2(19)=2x

2x=360-38

2x=322

x=161°

m<1=161°

Suppose a teacher finds that the
horsena [70]

Answer:

Scores = 8

Step-by-step explanation:

To solve variation problems, you make mild assumptions and analogies

Let's score be represented with S

Let's Absences be represented with A.

Therefore

S varies inversely as A

S ~ 1/A

S = K/A

The K represents a contant notation so that we can easily figure the variation problem.

When Absences were 2

Scores were 12

S = K/A

12 = K / 2

Cross Multiply.

K = 24.

It means that, S = 24 / A.

For a student with 3 absences, the score would be:

S = 24 / A

S = 24 / 3

S = 8

Math is fun!
