Mathematics

Naily [24]3 years ago

Answer:

To find f-¹(x) of f(x) equate f(x) to y

That's

f(x) = y

So we have

y =  \frac{4x - 7}{10}

Next interchange the variables that's x becomes y and y becomes x

That's

x =  \frac{4y - 7}{10}

Next make y the subject

Cross multiply

We have

4y - 7 = 10x

Move -7 to the right side of the equation

4y = 10x + 7

Divide both sides by 4

We have the final answer as

y =  \frac{10x + 7}{4}

So

f ^{ - 1} (x) =  \frac{10x + 7}{4}

Hope this helps you

As the payroll manager for a particular company, your task is to complete the following weekly payroll record. The company pays
Ludmilka [50]

The total weekly pay of the company is $754.98

What is total hours worked for the week?

The overtime is the excess of  total hours, which is 47 hours, over the regular hours of 40 hours of work a week, in essence, overtime hours  is 7(47-40)

Overtime rate=regular hour pay*1.5

regular hour pay=$14.95

overtime rate=$14.95*1.5

overtime rate=$22.425

overtime pay for 7 hours=7*$22.425

overtime pay for 7 hours=$156.98

The regular pay is 40 hours of regular time multiplied regular pay per hour

regular pay=$14.95*40

regular pay=$598.00

total pay=regular pay+overtime

total pay=$598.00+$156.98

total pay=$754.98
