Given that segment $TQ$ is $26$ units long, what is the length of $QV$ if $TQ$ and $QV$ are collinear and $TQ$ is a part of $TV$ where $TV$ is $32$ units long?

Use the figure to find each vector: u - v. Use vector notation as in Example 4.

Use the figure to find each vector: - v. Use vector notation as in Example 4.

Refer to vectors a through h below. Make a copy or a sketch of each vector, and then draw a sketch to represent each of the following. For example, find a + e by placing a and e so that their initial points coincide. Then use the parallelogram rule to find the resultant, as shown in the figure on the right.

a + b
