Answer: 4

Which complex number has a distance of 17 from the origin on the complex plane?
Virty [35]

Answer:

None of the options are correct.

Step-by-step explanation:

Let the complex number is a + ib

Given distance from origin = 17 units

Now, by distance formula distance of a point  from the origin  =

17 = \sqrt{(x)^{2}  + (y)^{2} }

1) <u>Check for 2 + 15 i</u>

here, \sqrt{15^2  +  2^2}  = \sqrt{225 + 4} = \sqrt{229} ≠ 17

2)<u> Check for 17 +  i</u>

here, \sqrt{17^2  +  1^2}  = \sqrt{289 + 1} = \sqrt{290}≠ 17

3)<u> Check for 20 - 3 i</u>

here, \sqrt{20^2  +  (-3)^2}  = \sqrt{400 + 9} = \sqrt{409}≠ 17

4) <u>Check for 4 -  i</u>

here, \sqrt{4^2  +  (-1)^2}  = \sqrt{16 + 1} = \sqrt{17} ≠ 17

Hence,  none of the options are correct.
