Question

а(1,-3) b(2,-3) найдите | a+b| наверху букв стрелки

Answer 1

Нужно найти координаты a+b?

a+b (3;-6)

Answer 2

1) Пусть вектор a+ вектор b= вектору m. Тогда, вектор m= (3; -6)

2) |вектор m|= корень из (9+36)= корень из (45)=3 корня из 5

Ответ: |вектор a+ вектор b|= 3 корня из 5

 

Answer 3

Calculation of |a + b|

To find the value of |a + b|, where a = (1, -3) and b = (2, -3), we need to calculate the sum of the two vectors and then find the magnitude of the resulting vector.

The sum of the two vectors a and b can be calculated by adding their corresponding components:

a + b = (1 + 2, -3 + (-3)) = (3, -6)

Now, we need to find the magnitude of the resulting vector (3, -6). The magnitude of a vector can be calculated using the Pythagorean theorem:

|m| = sqrt(x^2 + y^2)

where x and y are the components of the vector.

For the vector (3, -6), the magnitude can be calculated as follows:

|m| = sqrt(3^2 + (-6)^2) = sqrt(9 + 36) = sqrt(45) = 6.708

Therefore, the magnitude of the vector (3, -6) is approximately 6.708.

Answer: The magnitude of the vector |a + b| is approximately 6.708.
