Solution

The dot product of two vectors is calculated by multiplying the corresponding components of the vectors and then adding those products together.

For the vectors <1, -2> and <3, 2>, the dot product is calculated as follows:

(1 * 3) + (-2 * 2) = 3 - 4 = -1

So, the dot product of <1, -2> and <3, 2> is -1.
