Geometrically, the arc length, s, is directly proportional to the magnitude of the central angle, θ, according to the formula s = rθ. In our diagram the radius of the circle, r, is equal to L, the length of the pendulum. Thus, s = Lθ, where θ must be measured in radians. Substituting into the equation for SHM, we get
Examples For each of the following relationships, graph the proportional relationship between the two quantities, write the equation representing the relationship, and describe how the unit rate, or slope is represented on the graph. Example 1: Gasoline cost $4.24 per gallon.
Circle the table letter below that represents a proportional relationship to this original table: Cups of flour Number of cookies 0.5 1 dozen. 1.5 doz. en 3 6 dozen. Cups of flour Number of cookies 1 2 dozen. 0.
Given a proportional relationship, students will be able to graph a set of data from the relationship and interpret the unit rate as the slope of the line.
Some examples of the importance of this relationship The ratio of surface area to volume of a baby is much greater than that of an adult. Heat production is more or less proportional to volume. loss and gain is proportional to surface area. As a result, in unfavorable
Graphing Proportional Relationships - Example2. Another common example of directly proportional relationships is that between time and distance when travelling at a constant speed. The graph below shows the relationship between distance and time for a vehicle travelling at a constant speed of 30 miles per hour.
