Question

calcule a distancia entre os pontos,
a)A (2,3) e b (2,5)
b)A(2,1) e B (-2,4)
c)A (6,3) e B (1,5)
d)A (6,3) e B (2,7)
e) A(4,3) e B (0,0)
f)A(-1,-1) e B (1,1)

Answer 1

a)A(2,3) e B(2,5)
DAB=√(xB-xA)²+(yB-yA)²
DAB=√(2-2)²+(5-3)²
DAB=√(0²+(2)²
DAB=√4= "2"

C) A(6,3) e B(2,7)
DAB=√(xB-xA)²+(yB-yA)²
DAB=√(2-6)²+(7-3)²
DAB=√(4)²+(4)²
DAB=√16+16="32"

F) (A(-1,-1) e B(1,1)
DAB=√(xB-xA)²+(yB-yA)²
DAB=√(1-(-1)²+(1-(-1)²
DAB=√(1+1)²+(1+1)²
DAB=√4+4=
DAB=√8=√2².2=2√2
