True or false: If $a\text{⃗}=⟨3,-2⟩$ and $b ⃗$ has initial point $(-10,5)$ & terminal point $(-7,3)$, then $a ⃗=b ⃗$.

True or false: If $a\text{⃗}=⟨3,2⟩$ and $b ⃗$ has initial point $(3,-1)$ & terminal point $(6,1)$, then $a ⃗=b ⃗$.

If vector $v\text{⃗}=⟨-4,-10⟩$, calculate the magnitude $|v ⃗ |$.

If vector $v\text{⃗}$ has initial point $(-1,2)$ and terminal point $(9,5)$, calculate the magnitude $|v ⃗ |$.

If vectors $v\text{⃗}=⟨2,1⟩$, $u\text{⃗}=⟨3,4⟩$, and $w\text{⃗}=⟨-1,1⟩$, calculate $v\text{⃗}+u\text{⃗}-w\text{⃗}$.

If vectors $v\text{⃗}=⟨4,1⟩$, $u ⃗=⟨-8,3⟩$, and $w ⃗=⟨-2,-1⟩$, calculate $w ⃗-3(v ⃗+u ⃗)$.
