Question

What is true about the complex number -5 - 5i? Check all that apply.
A. It lies in quadrant 2.
B. It lies in quadrant 3.
C. The modulus is 5.
D. The modulus is .

Answer 1

Any idea?

Answer 2

absolutely not... @OOOPS

Answer 3

oh D should read "the modulus is 5 Root2"

Answer 4

Is it B and D @OOOPS

Answer 5

The modulus is the distance from the origin right?

Answer 6

just one is correct, choose

Answer 7

so the modulus is
\[\sqrt{5^2 + 5^2}\]

Answer 8

I can check all that apply.

Answer 9

but to this problem, only one is correct

Answer 10

you move -5 on the real axis and -5 on the imaginary axis, that is a triangle with legs 5 and 5, the hypotenuse is the distance from the origin and the modulus

Answer 11

square root of 50 is the modulus

Answer 12

or 5 root 2

Answer 13

and that is quadrant 3

Answer 14

just jot it down, you can see everything, oh, Dan did. :)
