Question

encontre a distancia entre os pontos dados
a) A(5, 2) e B(1, 3)
b) E(-4.-3) e O(0,0)
f) J(-2,-1) e K(3,-4)
h) N(Raiz de 2, - Raiz de 2) e P(- raiz de 2, raiz de 2)

Answer 1

a) = (1-5, 3-2) = (-4, 1)
d = √(-4^2) + (1^2)
d= √9 = 3

b) = (0-(-4), 0-(-3)) = (4,3)
d = √(4^2)+(3^2)
d = √25 = 5

f) = (3-(-2), -4-(-1))
= (5, -3)
d= √(5^2)+(-3^2) = 34

h) (-√2-(√2), √2-(-√2)) = (-2√2, 2√2)
d = √8 + 8
d = √16 = 4
