Answer:
|u| = √29
Explanations:
Since we are only given one vector, we cannot compute its dot product. However, the magnitude of a vector (x, y) is expressed as:
[tex]|u|=\sqrt{x^2+y^2}[/tex]
Given the vector u = (-2, -5), the magnitude of u is expressed as:
[tex]\begin{gathered} |u|=\sqrt{(-2)^2+(-5)^2} \\ |u|=\sqrt{4+25} \\ |u|=\sqrt{29} \end{gathered}[/tex]
Hence the magnitude of the vector in radical form is √29
