Answer:

The answer is

<h2>20 + 56i</h2>

Step-by-step explanation:

(2 -10i) (-5 + 3i)

Using FOIL multiply each term in the first bracket by the terms in the second <u>bracket</u>

That's

2(-5) + 2(3i) - 10i(-5) - 10i(3i)

<u>Multiply the numbers and simplify</u>

We have

- 10 + 6i + 50i - 30i²

From the rules of imaginary numbers

<h3>i² = - 1</h3>

So we have

- 10 + 56i - 30(- 1)

- 10 + 56i + 30

Simplify

30 - 10 + 56i

We have the final answer as

<h3>20 + 56i</h3>

Hope this helps you

barxatty [35]

The amount of money worker will take home is €24752.6

<h3>What is gross pay?</h3>

Gross pay is the amount earned by any individual without any deductions of the taxes, and charges. It is the total amount of money earned by anyone.

Given that:-

  • The gross pay of a worker in a factory is €30800.60 per annum. If €504 is deducted from his salary month.

The amount of money he will take home will be calculated as:-

Gross pay = €30800.60

Deductions = €504 per month = 504 x 12 = €6048 per year.

So net pay = 30800.6 - 6048 =  €24752.6

Therefore the amount of money the worker will take home is €24752.6
