What is the modulus of 5 - 3i

Mathematics

DaniilM [7]3 years ago

Hello!

The above expression exemplifies a “complex number.” A complex number takes the following form:

a + bi

In this case, A is equal to (5) while B is equal to (-3). To find the modulus of a complex number, we will need to use the following formula (let “x” represent the modulus):

x = √(a² + b²)

Insert any known values into the formula above:

x = √((5)² + (-3)²)

Simplify the right side of the equation:

x = √(25 + 9)
x = √34

We have now proven that the modulus is equal to √34.

I hope this helps!

Tony buys a washing machine
Lorico [155]

Step-by-step explanation:

£480 = 120% (after adding the 20% VAT).

we want to know how much 100% is.

he do we get from 120% to 100% ?

first the formal long way

£480 = 120%

1% = 120%/120 = 480/120 = £4

100% = 1% × 100 = 4×100 = £400

once you understand this mechanism, you can apply the direct shortcut :

£480 / 1.2 = £400

as a multiplication with 100/120 is the same as a division by 120/100, which is 1.2.

and what we did at the beginning in long form was nothing else than

£480 × 100/120 = 480 × 10/12 = 480 × 5/6 = £400
