Question

determine a distância entre os pontos.​

Answer 1

g)

d^2 = (Xa-Xb)^2 + (Ya-Yb)^2

d^2 = [-4-(-4)]^2 + [3-(-7)]^2

d^2 = √100

d = 10

h)

d^2 = (Xa-Xb)^2 + (Ya-Yb)^2

d^2 = [√2-(-√2)]^2 + (-√2-√2)^2

d^2 = (√2+√2)^2 + (-2√2)^2

d^2 = 8 + 8

d = √16

d = 4

i)

d^2 = (Xa-Xb)^2 + (Ya-Yb)^2

d^2 = [1-(-3)]^2 + (3-3)^2

d^2 = 16 + 0

d = √16

d = 4
