Question

calcule a distância entre os pontos dados:​

Answer 1

a)

[(2 - 3)^2 + (4 - 1)^2]^(1/2)

[(-1)^2 + 3^2]^(1/2)

[1 + 9]^(1/2)

10^(1/2)

b)

[(-6 - (-5))^2 + (5 - 1)^2]^(1/2)

[(-6 + 5)^2 + 4^2]^(1/2)

[(-1)^2 + 16]^(1/2)

[1 + 16]^(1/2)

17^(1/2)

c)

[(3 - (-2))^2 + (-1 - 4)^2]^(1/2

[(3 + 2)^2 + (-5)^2]^(1/2)

[5^2 + 25]^(1/2)

[25 + 25]^(1/2)

[50]^(1/2)

10^(1/2)

5 * 2^(1/2)
