Question

1). Calcule a distância entre os seguintes pontos:



a) P(5; 2), Q(6 ; 3)

b)P( 4; 2 ) Q ( 8 ; 2 )​

Answer 1

Resposta:

Explicação passo-a-passo:

$d = \sqrt(x_1 - x_2)^2 + (y_1-y_2)^2\\\\\\\\a) d = \sqrt(5-6)^2 + (2-3)^2\\\\\\d= \sqrt 1+ 1 = \sqrt2\\\\\\\\b) d= \sqrt (4 - 8)^2 + (2-2)^2\\d= \sqrt 16 + 0 =4$
