## anonymous 5 years ago Please answer! Find distance from -5+4i to 0

1. anonymous

wouldn't you just set it equal to 0? If that is the case it is 5/4

2. anonymous

use distance formula d^2 = (-5)^2 + 4^2

$\sqrt{(-5^{2}+(4i)^{2}}$ would this do it?

$\sqrt{25+(-16)}=\sqrt{9}=\pm3$

5. anonymous

But it asks for the distance from 0 to (-5+4i) is that still right

It is a complex number containing a real component (-5) and the imaginary component 4i

Helllllp

I get it now! Thanks

sqrt(5^2+4^2)=sqrt(25+16)=sqrt(41)
