5. Burning Candles, Part 3 Consider the following graph for another group of three burning candles. Each line represents a different candle. NWAMANOOO Height (cm) -p Q R 0 7 8 9 10 11 12 13 14 15 16 17 Time (min) a. What was the starting height of each candle? b. At what rate did each candle burn? How do you know? c. What is the slope of each line? d. Which of the groups of candles shown could be represented by the graph and why? Which candle is Candle P? Candle Q? Candle R? e. Write an equation to represent each candle's burning. (It might help to make a table of data for each candle first.) f. How are the three equations alike? Group 1 Group 2 Group 3 How are they different? g. Write an equation for a fourth candle, Candle S, whose graph will intersect the point (0, 8) as do the other three lines. h. Sketch the graph of your equation for Candle S on the same grid with the graphs for Candles P, Q, and R. i. Describe or draw Candle S that you represented by the graph and equation in parts (g) and (h). 6. The accompanying graph shows the number of quarts of strawberries picked by three people one morning. 96 a. One person was scared by a snake and quit picking. Annette 84 Who was that? How do you know? b. How many quarts does Annette pick per hour? 72 c. At what time did Barb start picking? How many 60 Cindy Number of quarts picked quarts does she pick per hour? 48 d. Which person picks strawberries most quickly? 36 How do you know? Barb 24 7. The next morning Annette (see Learning Exercise 6) 12 - was ill.
