Question

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

Answer 1

Answer:

B

Step-by-step explanation:

Answer 2

Answer:

b) √29

Step-by-step explanation:

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

We need to use the distance formula.

Distance formula = $\sqrt{(x2 -x1)^2 + (y2 - y1)^2}$

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

Distance = $\sqrt{(2 -0)^2 + (-5 - 0)^2}$

= $\sqrt{2^2 + (5)^2}$

= √(4 + 25)

= √29

The answer is b) √29

Hope you will understand the concept.
