If log x - log(2x-1)=1 find x​
Zinaida [17]

✿━━━━@♥ℳg━━━━✿

<h2>\boxed{Explained\:Answer}</h2>

______________________________

✿━━━━@♥ℳg━━━━✿

f (x) = log ( 1+x / 1-x ) ---- 1

f ( 2x / 1+x2 )   = ???

to find this -----  in equation 1 replace "x" by  ( 2x / 1+x2 )

then

f ( 2x / 1+x2 ) = log ( 1 + x2 + 2x  / 1 + x2 - 2x )

f ( 2x / 1+x2 ) =  log ( 1+x / 1-x ) 2

f ( 2x / 1+x2 ) = 2 log ( 1+x / 1-x )

 f ( 2x / 1+x2 ) = 2 f(x)

Cheers....

Hey guys, I need help with these Scale factor problems! problems are linked in a screenshot below:
AVprozaik [17]

Answer:

  1. A → B: 1/3
  2. correct
  3. A → B: 2/5

Step-by-step explanation:

It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.

  1. A → B = 1/3; B → A = 3
  2. A → B = 2; B → A = 1/2
  3. A → B = 2/5; B → A = 5/2

__

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.

  1. B : A = 1 : 3
  2. A : B = 1 : 2
  3. B : A = 2 : 5

Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.

. Isabella buys a 1.75 litre carton of apple juice. What is the largest number of 200 millilitre glasses that she can have from
Free_Kalibri [48]

Answer:

<em>The largest number of glasses of juice Isabella can have from the carton is 8.</em>

Step-by-step explanation:

<u>Ratios</u>

Knowing the total capacity of the carton of apple juice Ct, and the capacity of each glass Co, we can calculate how many glasses can be taken from the carton by finding the ratio:

\displaystyle n=\frac{Ct}{Co}

There are 1,000 milliliters in one liter, thus the carton has a capacity of

C t= 1.75*1,000 = 1,750 milliliters

Thus,

\displaystyle n=\frac{1,750}{200}

n=8.75

Since we cannot have 8.75 glasses, we round to the previous integer, then:

The largest number of glasses of juice Isabella can have from the carton is 8.
