Question

calculate the distance of (3,-4)from the origin​

Answer 1

Answer:

5

Step-by-step explanation:

Origin (0,0)

A(3,-4)

lenght = sqr root ( (x1 - x2)^2 + (y1 - y2)^2  )    or length ^ 2 = (x1 - x2)^2 + (y1 - y2)^2

So:

(3 - 0)^2 + (-4 - 0)^2 = length^2

9 + 16 = length^2

length = sqr root (25)

length = 5
