Question

найдите расстояния между точками C(3;8) и D(-1;5)

Answer 1

R = √ (Xd-Xc)^2 + (Yd-Yc)^2 = √ (-1-3)^2 + (5-8)^2 = √(16+9)= 5

Answer 2

I can help you with your math question. To find the distance between two points, you can use the formula:

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

In your case, the points are C(3;8) and D(-1;5), so you can plug in the values of x and y:

$$d=\sqrt{(-1-3)^2+(5-8)^2}$$

Then, you can simplify the expression by following the order of operations:

$$d=\sqrt{(-4)^2+(-3)^2}$$ $$d=\sqrt{16+9}$$ $$d=\sqrt{25}$$ $$d=5$$

Therefore, the distance between the points C and D is 5 units. I hope this helps.Ответь+подробно.+найдите+расстояния+между+точками+C(3;8)+и+D(-1;5)
