Question

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

Answer 1

d = 13

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
