Use absolute value to express the distance between −13 and 17 on the number line. |−13 − 17| = −30
|−13 − 17| = 30
|−13 − 17| = −4
|−13 − 17| = 4

Data are collected to see how many ice-cream cones are sold at a ballpark in a week. day 1 is sunday and day 7 is the following saturday. use the data from the table to create a scatter plot.

Suppose that the price p (in dollars) and the weekly sales x (in thousands of units) of a certain commodity satisfy the demand equation 4p cubedplusx squaredequals38 comma 400. determine the rate at which sales are changing at a time when xequals80, pequals20, and the price is falling at the rate of $.20 per week.

The measure of angle 0 is 600 degrees
