Question

Writing Vectors in Terms of$i$and $j$Write the given vector in terms of$i$and $j$

$\mathbf{u}=⟨-2,10⟩$

Short answer

The vector $\mathbf{u}=⟨-2,10⟩$ in terms of $i$ and $j$ can be written as $\text{-2 i+10 j}$ .

Step-by-step solution

Step 1.Given information.

Given: $\mathbf{u}=⟨-2,10⟩$

Step 2. To write the given vector in terms of i and j.

Write the given vector$⟨-2,10⟩$as coefficient of$i$and$j$respectively.

$\begin{array}{l}u=⟨-2,10⟩\\ u=(-2)i+\left(10\right)j\\ u=-2i+10j\end{array}$
