Question

calcule a distância entre os pontos c(3,5) e d(-3,12)

Answer 1

$c(3,5);d(-3,12)\\\\\\ D_{c,d} = \sqrt{ ( x_{d} - x_{c} )^{2} + ( y_{d} - y_{c} )^{2} } \to \\\\\\ D_{c,d} = \sqrt{ ( -3-3)^{2} + ( 12-5 )^{2} } \to \\\\ D_{c,d} = \sqrt{ ( -6 )^{2} + ( 7 )^{2} } \to \\\\ D_{c,d} = \sqrt{36+49 } \to \\\\ D_{c,d} = \sqrt{85 } \to \\\\ D_{c,d} = 9,2$
