2.  A vector is any quantity that has magnitude (size) and direction.  A vector is used to describe translations.

3.  Vectors can be written as an ordered pair   These are the components of the vector. 2 is the x component and -3 is the y component.  To find the magnitude of the vector use pythagorean theorem. √(2 2 + (-3 2 ))

5.  To find the x component take the cosine of the angle formed from the vector and the x- axis and multiply it by the magnitude.  To find the y component take the sine of the angle formed from the vector and the x-axis and multiply it by the magnitude.

6.  What do you call a teapot of boiling water on top of Mount Everest?  A high-pot-in-use

7.  A new government 10 year survey cost $3,000,000,000 revealed that 3/4 of the people in America make up 75% of the population.
