Question

Please answer!
Find distance from -5+4i to 0

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

Helllllp

Answer 9

I get it now! Thanks

Answer 10

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

Answer 11

I see where I went astray, I inludec i squared which is a -1, when I should of ignored the fact there was an i, as I was actually getting the absolute value.
