Answer:

Answer: Choice C

Explanation:

The Magnitude of a Vector

Given a vector in the form:


\mathbf{v}=x\mathbf{i}+y\mathbf{j}

The magnitude of the vector is:


\mid\mid \mathbf{v}\mid\mid=√(x^2+y^2)

We are given the vector:


\mathbf{v}=17\mathbf{i}-39\mathbf{j}

The magnitude is:


\mid\mid \mathbf{v}\mid\mid=√(17^2+(-39)^2)


\mid\mid \mathbf{v}\mid\mid=√(289+1521)=√(1810)
