Question

What is the distance from the origin of point P graphed on the complex plane below?

Answer 1

B

Explanation:

Answer 2

b) √29

Explanation:

Given: The origin is (0, 0), the point P is (2, -5).

We need to use the distance formula.

Distance formula =
`√((x2 -x1)^2 + (y2 - y1)^2) \\`

Here x2 = 2, x 1 = 0, y1 =0, y2 = -5

Distance =
`√((2 -0)^2 + (-5 - 0)^2)`

=
`√(2^2 + (5)^2)`

= √(4 + 25)

= √29

The answer is b) √29

Hope you will understand the concept.

Thank you.
