Question

1) Encontre a distância entre as coordenadas abaixo.

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

b) A(10,7) e B(4,-1)

c) A(11,15) e B(2,3)

d) A(13,18) e B(1,2)

e) A(9,10) e B(3,2)​

Answer 1

a)

dAB²=(3-7)²+(2-5)²

dAB=\/(-4)²+(-3)²

dAB=\/16+9

dAB=\/25

dAB=5

b)

dAB=\/(4-10)²+(-1-7)²

dAB=\/(-6)²+(-8)²

dAB=\/36+64

dAB=\/100

dAB=10

c)

dAB=\/(2-11)²+(3-15)²

dAB=\/(-9)²+(-12)²

dAB=\/81+144

dAB=\/225

dAB=15

d)

dAB=\/(1-13)²+(2-18)²

dAB=\/(-12)²+(-16)²

dAB=\/144+256

dAB=\/400

dAB=20

e)

dAB=\/(3-9)²+(2-10)²

dAB=\/(-6)²+(-8)²

dAB=\/36+64

dAB=\/100

dAB=10
