Question

Calcule a Distancia entre os pontos
a) E(-4,-3) e O (-2,-5)
b) F (-5,4) e G (2,-5)
c) H (-1,5) e I (-1,12)
d) N(V[2,-V[2] e P (-V[2],V[2])

Answer 1

Explicação passo-a-passo:

a) E(-4,-3) e O (-2,-5)

D=√(∆x)²+(∆y)²

D=√(-4+2)²+(-3+5)²

D=√(-2)²+(2)²

D=√4+4

D=√2.4

D=2√2

b) F (-5,4) e G (2,-5)

D=√(∆x)²+(∆y)²

D=√(-5-2)²+(4+5)²

D=√(-7)²+(9)²

D=√49+81

D=√130

c) H (-1,5) e I (-1,12)

D=√(∆x)²+(∆y)²

D=√(-1+1)²+(5-12)²

D=√(0)²+(-7)²

D=√0+49

D=√49

D=7

d) N(V[2,-V[2] e P (-V[2],V[2])

D=√(∆X)²+(∆y)²

D=√(√2+√2)²+(-√2-√2)²

D=√(2√2)²+(-2√2)²

D=√8+8

D=√16

D=4
