Question

найдите расстояние между точками А и В,если А(а-0,2),В(б+0,5),а-б=-1Помогите,срочно надо!

Answer 1

A-B=|(a-0,2)-(b+0,5)|=|(a-b)-0,7|=|-1-0,7|=|-1,7|=1,7

Answer 2

Calculating the Distance Between Points A and B

To calculate the distance between points A and B, we can use the formula for the distance between two points in a plane, which is given by:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

Given that A(a, 0.2) and B(b, 0.5), and a - b = -1, we can proceed with the calculation.

First, let's find the coordinates of points A and B: - A(a, 0.2) - B(b, 0.5)

Now, we can calculate the distance using the formula: Distance = √((b - a)^2 + (0.5 - 0.2)^2)

Let's substitute the value of a - b = -1 into the formula and calculate the distance.

Distance = √((-1)^2 + (0.3)^2)

Distance = √(1 + 0.09)

Distance = √1.09

Distance ≈ 1.043

So, the distance between points A and B is approximately 1.043.
