Rates of change can be positive or negative. This corresponds to an increase or decrease in the y -value between the two data points. When a quantity does not change over time, it is called zero rate of change. Positive rate of change When the value of x increases, the value of y increases and the graph slants upward. Negative rate of change 4. When the dependent variable increase as the independent variable stays the same, the rate of change is (Positive, negative, zero, undefined) circle one. Find the rate of change (Hint: word problems are units Identify what you are given and determine the unit and the time.) time Write the ordered pair (time, units). 5. X Y 20 35 25 40 6.

Problem 1 A rectangular water tank (see figure below) is being filled at the constant rate of 20 liters / second. The base of the tank has dimensions w = 1 meter and L = 2 meters. What is the rate of change of the height of water in the tank?(express the answer in cm / sec). Solution to Problem 1: The volume V of water in the tank is given by. A rate of change is a rate that describes how one quantity changes in relation to another quantity. Rates of change can be positive or negative. This corresponds to an increase or decrease in the -value between the two data points. When a quantity does not change over time, it is called zero rate of change. Find the average annual rate of change in dollars per year in the value of the house. Round your answer to the nearest dollar. (Let x = 0 represent 1990) For this problem, we don't have a graph to refer to in order to identify the two ordered pairs. Therefore, we must find two ordered pairs within the context of this problem.
