Question

What is the distance between -2-3i and 3+9i

Answer 1

Answer:

d = 13

Step-by-step explanation:

The distance formula in a complex plane is $\sqrt{(s-a)^{2} + (t-b) }$. Let us say that points (a,b) are (-2,-3) and points (s,t) are (3,9), both coordinates derived from given. Substitute the numbers into the equation to get the distance.

d = $\sqrt{(3-(-2))^{2} + (9-(-\\3))^{2} }$

d = 13
