Answer: second option

Step-by-step explanation:

To find the inverse function of the given function f(x):

f(x)=2x

You need to:

Substitute f(x)=y into the function:

 y=2x

Now, you need  to solve for "x", to do this, you must divide both sides of the function by 2:

\frac{y}{2}=\frac{2x}{2}\\\\\frac{y}{2}=x

Now, replace "x" with "y" and replace "y" with "x":

\frac{x}{2}=y

Therefore, substituting y=f^{-1}(x) you get:

f^{-1}(x)=\frac{x}{2} or  f^{-1}(x)=\frac{1}{2}x

Peter Chibwe works at Company XYZ. The following information relates to his performance at work for a single week Deductions are
Colt1911 [192]

The question is related to Payroll Administration and Management.

Where the weekly gross is $10,000 the Net Pay is $ 7,240 while monthly Net Pay is $ 28,960.00.

<h3>What is Payroll Administration?</h3>

This is defined as the series of task required to organize the compensation an benefits of the employee for the period that they have spent working.

<h3>The solution is given below:</h3>

A) Note that the information given above is for a week. We are not given the gross wage. Hence we'd assume that the gross wage for the week is $10,000.

If gross pay is $10,000, Net Pay is calculated by removing deductions.

Deductions are:

Pension fund = 7.5% of 10,000 = $750

PAYE Tax = 20% of (95% of 10,000) = $1,900 This is because medical aid is non-taxable.

Employee Insurance = 1% of 10,000 = $100

Union Membership = $10

The Total Deduction thus is = 750 + 1,900 + 100 +10 = $2, 760.00

The Net pay =  Gross Pay Less Deductibles

= 10,000-7,760

Thus The Net pay = $ 7,240/Week.

His weekly net wage will be:

7,240 * 4 = $28,960.00/Month

B) The kind of remuneration method used by company XYZ is

Time Rate System. Under the time rate system, the worker is paid per hour, per day, per week, or per month.

It is normally used for workers who are engaged on highly skilled jobs or highly skilled services, for example, equipment testing, or inspection of operations, toolmaking, etc.

Can someone help me find the angle measurements
agasfer [191]

Answer:

12. 50 degrres

13. 90 degrees

14. 40 degrees

15. 50 degrees

16. 130 degrees

17. 90 degrees

Step-by-step explanation:

12. Angle UAY is equal to 50 degrees as it is stated in the graph

13. Angle YAZ is 90 degrees, as there is a square at the angle, meaning that the angle is a right angle.

14. Angle ZAX + Angle UAY + Angle YAZ = 180, as it is supplementary.

We know Angle UAY and Angle YAZ, so we can find Angle ZAX

Angle ZAX = 180 - UAY - YAZ = 180 - 50 - 90 = 40 degrees

15. Angle XAW = 50 degrees, as it is vertical angles with Angle UAY.

16. Angle WAU = Angle YAX = Angle YAZ + Angle ZAX = 90 + 40 = 130 degrees

17. Angle ZAW and Angle YAZ are supplementary, so they add up to 180 degrees.

Angle YAZ = 90 degrees, so Angle ZAW must also equal 90 degrees.
