Question

LEMBRANDO QUE AS COORDENADAS DE A SÃO (-1,3) E C(3/2,4) ALGUÉM SABE O VALOR ?

CONSIDERE OS PONTOS REPRESENTADOS NO PLANO A SEGUIR E DETERMINE:


a) A distância de A até C

Answer 1

Só colocar na formula:

$Distancia=\sqrt{(x_c-x_a)^2+(y_c-y_a)^2}\\\\Distancia=\sqrt{(\frac{3}{2}-(-1))^2+(4-3)^2}\\\\Distancia =\sqrt{(\frac{3}{2}+1)^2+(1)^2}\\\\Distancia =\sqrt{(\frac{3.1+1.2}{2})^2+1}\\\\Distancia =\sqrt{(\frac{5}{2})^2+1}\\\\Distancia =\sqrt{\frac{25}{4}+1}\\\\Distancia =\sqrt{\frac{25}{4}+\frac{1}{1}}\\\\MMC\;entre\;1\;e\;4=4\\\\Distancia =\sqrt{\frac{25.1+1.4}{4}}\\\\Distancia =\sqrt{\frac{25+4}{4}}\\\\Distancia =\sqrt{\frac{29}{4}}\\\\Distancia = \frac{\sqrt{29}}{2}$
