Question

Calcule a distancia entre os pontos A (-2,3) e B (3,4)

Answer 1

D a,p = [(3+2)²+ (4-3)²]^1/2
D a,p = [5²+1²]^1/2
D a,p = 26^1/2

Espero ter ajudado!

Answer 2

dAB = $\sqrt{(xB-xA)^2+(yB-yA)^2}$

xA = - 2
xB = 3

yA = 3
yB = 4

dAB = $\sqrt{[3-(-2)]^2+(4-3)^2}$

dAB = $\sqrt{(3+2)^2+(1)^2}$

dAB = $\sqrt{25+1}$

dAB = √26
