Question

Calcula a distância(comprimento) do segmento AB:

a) A(-2,2) e B(1,-3)

b) A(3,-1) e B (3,5)

c) A(0,-2) e B (5,-2)

Answer 1

Resposta:

resposta A ) (-2,2 e B (1,-3

Answer 2

Resposta:

a) $\sqrt{34}$ b) 6 c) 5

Explicação passo a passo:

utilizasse a formula dab=$\sqrt{(Xb-Xa)^2+(Yb-Ya)^2}$

logo

a) $\sqrt{(1-(-2))^2+(-3-2)^2}$ -> $\sqrt{9+25}$=$\sqrt{34}$

b) $\sqrt{(3-3)^2+(5-(-1))^2}$ -> $\sqrt{0+36}$ = 6

c) $\sqrt{(5-0)^2 + (-2-(-2))^2}$ -> $\sqrt{25+0}$ = 5
