If and are vectors, and is a scalar, which of the following is true?

Work done by a force in moving an object along a vector is calculated by:

A negative value for the dot product of two vectors implies the angle between them is:

The horizontal and vertical components of a vector represent:

If the angle between two vectors is acute, their dot product is:

The component of along is given by the formula:

The projection of onto is defined as:

According to De Moivre’s Theorem, to find the th power of a complex number, you take the th power of the modulus and:

To graph a complex number , we plot the ordered pair in a plane called the:

The graph of a complex number is a point in the complex plane. What does the distance from this point to the origin represent?
