Question

calcule a distância entre os pontos A(3,4) e B(-3,1)​

Answer 1

Resposta:

$d = \sqrt{(xb - xa)} ^{2} + (yb - ya) {}^{2} \\ d = \sqrt{ ( - 3 - 3) ^{2} } + (1 - 4) ^{2} \\ d = \sqrt{( - 6) ^{2} } + ( - 3) ^{2} \\ d = \sqrt{36 + 9} \\ d = \sqrt{45}$

Answer 2

A(3, 4) B(-3, 1)

dist(A, B) = ((-3 - 3)^2 + (1 - 4)^2)^(1/2)
dist(A, B) = ((-6)^2 + (-3)^2)^(1/2)
dist(A, B) = (36 + 9)^(1/2)
dist(A, B) = (45)^(1/2)
