Vectors

Vector $$\overrightarrow{AB}$$ is equivalent to __________.

$$\overrightarrow{OY} = 10\mathbf{a} + 9\mathbf{b}$$

$$\overrightarrow{OY} = 40\mathbf{a} + 36\mathbf{b}$$

$$\overrightarrow{OY} = 5\mathbf{a} + 9\mathbf{b}$$

$$\overrightarrow{OY} = 20\mathbf{a} + 9\mathbf{b}$$

Vector $$\overrightarrow{OA} = 20\mathbf{a} + 18\mathbf{b}$$. $$Y$$ is the midpoint of $$\overrightarrow{OA}$$. Find the vector $$\overrightarrow{OY}$$ in terms of $$\mathbf{a}$$ and $$\mathbf{b}$$

$$\overrightarrow{OB} = 10\mathbf{a} + 9\mathbf{b}$$

$$\overrightarrow{OB} = 40\mathbf{a} + 36\mathbf{b}$$

$$\overrightarrow{OB} = 5\mathbf{a} + 9\mathbf{b}$$

$$\overrightarrow{OB} = 20\mathbf{a} + 9\mathbf{b}$$

Vector $$\overrightarrow{OA} = 20\mathbf{a} + 18\mathbf{b}$$. $$A$$ is the midpoint of $$\overrightarrow{OB}$$. Find the vector $$\overrightarrow{OB}$$ in terms of $$\mathbf{a}$$ and $$\mathbf{b}$$ 

$$\frac{1}{2}\overrightarrow{BD}=\overrightarrow{BX}$$

$$2\overrightarrow{BD}=\overrightarrow{BX}$$

$$\frac{1}{2}\overrightarrow{BD}=0.5\bigg({2\choose3}+{6\choose-1}\bigg)$$

$$\frac{1}{2}\overrightarrow{BD}= 2\bigg({2 \choose 3}+{6 \choose -1}\bigg)$$

$$X$$ is the midpoint of the vector $$\overrightarrow{BD}$$. Which of the following statements are true?

$$\overrightarrow{PX}= 14\mathbf{a}-16\mathbf{b}$$ 

$$\overrightarrow{PX}= 7\mathbf{a}-8\mathbf{b}$$ 

$$\overrightarrow{PX}= 7\mathbf{a}+8\mathbf{b}$$

$$\overrightarrow{PX}= 3.5\mathbf{a}-4\mathbf{b}$$ 

$$X$$ is the midpoint of the vector $$\overrightarrow{PQ}$$. Which of the following is vector $$\overrightarrow{PX}$$?

$$\overrightarrow{OX}= 1.5\mathbf{a}+0.5\mathbf{b}$$ 

$$\overrightarrow{OX}= 3\mathbf{a}-\mathbf{b}$$ 

$$\overrightarrow{OX}= 1.5\mathbf{a}-0.5\mathbf{b}$$ 

$$\overrightarrow{OX}= 2.5\mathbf{a}-\mathbf{b}$$ 

$$\overrightarrow{OX}= 2.5\mathbf{a}+\mathbf{b}$$ 

The point $$X$$ is the midpoint of the vector $$\overrightarrow{OB}$$. Identify $$\overrightarrow{OX}$$.
