X = 1 + root 2 , find the value of (x - 1/x )^3​
steposvetlana [31]

Answer:

(\sqrt{2})^3

Step-by-step explanation:

Given the expression

(x - \frac{1}{x} )^3

Simplify

(\frac{x^2-x}{x} )^3

Given that x = 1+√2

Substitute

(\frac{(1+\sqrt{2} )^2-(1+\sqrt{2} )}{1+\sqrt{2} } )^3\\=( \frac{1+2\sqrt{2} +2 - 1 - \sqrt{2}}{1+\sqrt{2}} )^3\\= (\frac{\sqrt{2}+2}{1+\sqrt{2}})^3 \\Rationalize\\= (\frac{\sqrt{2}-2+2-2\sqrt{2}}{1-2})^3 \\=( \frac{-\sqrt{2}}{-1})^3 \\= (\sqrt{2})^3\\ \\

If you have 12% withheld for federal taxes, 7% for state taxes, and FICA is 7.65%, how much are your involuntary withholdings in
grandymaker [24]

Answer:

Step-by-step explanation:

The required withholding amounts are ...

  • federal tax = 0.12×$1375 = $165.00
  • state taxes = 0.07×$1375 = $96.25
  • FICA = 0.0765×$1375 = $105.19

So, the total involuntary withholding is ...

  $165.00 +96.25 +105.19 = $366.44

We want to find the voluntary withholding such that ...

  (gross pay) - (involuntary withholding) - (voluntary withholding) = (net pay)

Adding (voluntary withholding - net pay) to both sides of this equation, we get ...

  (gross pay) - (involuntary withholding) - (net pay) = (voluntary withholding)

Filling in the values we know gives ...

  $1375 -366.44 -725 = voluntary withholding = $283.56

Your voluntary withholding is $283.56.

Can someone plz help me it is timed I will give Brainliest IF IT IS CORRECT
Artyom0805 [142]

Answer:

C. 1.15<em>x</em> because adding 15% to the cost of the haircut is the same as multiplying the cost by 1.15.

Step-by-step explanation:

This answer is correct because, adding 0.15x (or 15%) to the total amount is the same as multiplying the cost by 1.15. This is because, the 1 that is added to 0.15 represents the total, since we are just multiplying instead of adding to it.

Hope this helps! :D

Select the correct answer.
Alexus [3.1K]

Answer:

C. Surveys  

Step-by-step explanation:

A primary source of information is the gathering of data that hasn't already been collected.

One of the best ways is to use a market research survey.

A, B, and D are wrong. They are all secondary sources — they provide information that someone else has generated.
