Question

Seja M o ponto médio do segmento de reta com extremidades localizadas nos pontos A(2, 5) e B(6, 15). Então as coordenadas de M são
a) (1, 10) b) (2, 15) c) (4, 6) d) (8, 12) e) (4, 10)

Answer 1

Resposta:

$\textsf{Leia abaixo}$

Explicação passo a passo:

$\mathsf{M_{AB}\left(\dfrac{x_A + x_B}{2}\:;\:\dfrac{y_A + y_B}{2}\right)}$

$\mathsf{M_{AB}\left(\dfrac{2 + 6}{2}\:;\:\dfrac{5 + 15}{2}\right)}$

$\mathsf{M_{AB}\left(\dfrac{8}{2}\:;\:\dfrac{20}{2}\right)}$

$\boxed{\boxed{\mathsf{M_{AB}\left(4\:;\:10\right)}}}\leftarrow\textsf{letra E}$

Answer 2

Resposta: E) ( 4 , 10 )

$\Large \boxed{ \begin{array}{c}\bf{M_{AB}\left(\dfrac{x_A + x_B}{2}\:;\:\dfrac{y_A + y_B}{2}\right)} \\ \bf{M_{AB}\left(\dfrac{2 + 6}{2}\:;\:\dfrac{5 + 15}{2}\right)}\\ \bf{M_{AB}\left(\dfrac{8}{2}\:;\:\dfrac{20}{2}\right)} \\ \bf{M_{AB}\left(4\:;\:10\right)} \\ \end{array}}$
