Question

What is true about the complex number -5 + 5i? More than one can apply.
A. The modulus is 10.
B. It lies in quadrant 4.
C. It lies in quadrant 2.
D. The modulus is 5 sqrt 2.

Answer 1

It's going to be quadrant 2, C. Because the x-axis being the reals and the y-axis being the imaginary part, so the -5=x-axis and 5=y axis lies on the quadrant 2.

Did that makes sense to u?

Answer 2

Yeah :)

Answer 3

What about the modulus?

Answer 4

It can't be the Modulus, it means the absolute value or you can say the magnitude. The modulus is actually 5√2.

Answer 5

So C and D. thank you :)
