Question

Знайти модуль вектора а, якщо а(1;2,-5)

Answer 1

Ответ:

√30

Объяснение:

√(1²+2²+(-5)²)=√(1+4+25)=√30

Answer 2

Finding the Module of Vector a

To find the module (or magnitude) of a vector, we can use the formula:

|a| = √(a1^2 + a2^2 + a3^2)

Given vector a as (1, 2, -5), we can calculate the module using the above formula:

|a| = √(1^2 + 2^2 + (-5)^2)

|a| = √(1 + 4 + 25)

|a| = √30

Therefore, the module of vector a is √30.
