Question

Determine M, ponto médio de AB, dados A(3, 22) e B(21, 26):​

Answer 1

Resposta:

formula

d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}d=(x2−x1)2+(y2−y1)2

a)

P(3,-3)

Q=(-3,3)

\begin{gathered}d= \sqrt{(-3-3)^2+(3-(-3))^2} \\ \\ d= \sqrt{(-6)^2+(3+3)^2} \\ \\ d= \sqrt{36+6^2} = \\ \\ d= \sqrt{36+36} \\ \\ d= \sqrt{72} \\ \\ d= \sqrt{2^2.2.3^2} \\ \\ d=2.3 \sqrt{2} \\ \\ d=6 \sqrt{2}\end{gathered}d=(−3−3)2+(3−(−3))2d=(−6)2+(3+3)2d=36+62=d=36+36d=72d=22.2.32d=2.32d=62

-----------------------------------3,3----------------------------------

C(-4,0)

D(0,3)

\begin{gathered}d= \sqrt{(0-4)^2+(3-0)^2} \\ \\ d= \sqrt{(-4)^2+3^2} \\ \\ d= \sqrt{16+9} \\ \\ d=\sqrt{25} \\ \\ d=5\end{gathered}d=(0−4)2+(3−0)2d=(−4)2+32d=16+9d=25d=5
