Answer:

√(65) = 8.06

Explanation:

Assuming u = <4, 7> then the coordinates of the vector are 4 and 7, then we must apply the magnitude formula.

$\sqrt{4^(2) + 7^(2) } =√(16 + 49) = √(6\\5)$

So, the answer is 8.06 (if you round to hundredths place... if more is required simply insert
$√(65\\)$ into your calculator).
