The table in Part A represents y as a function of x. This means that the value of Y is dependent on the value of X. The table can be represented by an equation that describes the relation of X and Y:

or

By substituting any value of X, you get a specific value of Y based from the given relationship, thus Y is a function of X.
For Part B, the value of f(150) is $470 and it represents the total cost for borrowing a rowboat for 150 hours. By substituting the value of x = 150 into the function, you get the total cost:
(z^6 - 8)(z^6 + 8) is the answer.
If you verify this by multiplying, you will see that:
(z^6 - 8)(z^6 + 8) = z^(6+6) + 8z^6 - 8z^6 - 64
= z^12 + 0 - 64
= z^12 - 64
Hope this helps,

Different regular shapes have certain formulas that you use to find their volume. For example
volume of a cube is Base x Width x height
Volume of cylinder is pie r^2 x h
etc...
Since the measure of an angle is 12 degrees less than the measure of its supplement, then x=180-x-12 or 2x=168 or x=84 and 180-x=96. Step 4. ANSWER: The angle is 84 degrees and its supplementary angle is 96 degrees.
