Question

Найти длину отрезка AB A(3;7) B(-5;13)

Answer 1

АВ = (-5-3;  13 - 7) = (-8; 8)
длина отрезка АВ = √(  (-8)² + 8²) = √(64 +64) = √128 = 8√2

Answer 2

I can chat with you in Russian. To find the length of the segment AB with endpoints A(3;7) and B(-5;13), we can use the distance formula:

$$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$

where $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the endpoints. Substituting the values, we get:

$$d = \sqrt{(-5 - 3)^2 + (13 - 7)^2}$$

$$d = \sqrt{(-8)^2 + (6)^2}$$

$$d = \sqrt{64 + 36}$$

$$d = \sqrt{100}$$

$$d = 10$$

Therefore, the length of the segment AB is 10 units.Ответь+подробно.+Найти+длину+отрезка+AB+A(3;7)+B(-5;13)
