Question

Determine a distancia entre os pontos:

a) A(1,1) e B(6,1)
b) A(2,3) e B(5,7)
c) A(-2,-4) e B(-2,0)
d) C(3,3) e D(4,-2)​

Answer 1

Explicação passo-a-passo:

a)

A(1,1) e B(6,1)

D=√(∆x)²+(∆y)²

D=√(1-6)²+(1-1)²

D=√(-5)²+(0)²

D=√25+0

D=√25

D=5

b)

A(2,3) e B(5,7)

D=√(∆x)²+(∆y)²

D=√(2-5)²+(3-7)²

D=√(-3)²+(-4)²

D=√9+16

D=√25

D=5

c) A(-2,-4) e B(-2,0)

D=√(∆x)²+(∆y)²

D=√(-2+2)²+(-4-0)²

D=√(0)²+(-4)²

D=√0+16

D=√16

D=4

d) C(3,3) e D(4,-2)

D=√(∆x)²+(∆y)²

D=√(3-4)²+(3+2)²

D=√(-1)²+(5)²

D=√1+25

D=√26
