A 12.5-inch candle is lit and burns at a constant rate of 1.2 inches per hour. Let t represent the number of hours that have elapsed since the candle was lit. a. Write an expression in terms of t that represents the number of inches that have burned from the candle since it was lit. I=12.5-1.2t * Preview b. Write an expression in terms of t that represents the remaining length of the candle (in inches). * Preview c. Determine if the following statements are true or false. Select an answer * The number of inches that have burned from the candle is proportional to the amount of time since the candle has been burning. Select an answer > * The remaining length of the candle is proportional to the amount of time since the candle has been burning. • Select an answer * The change in the candle's height is proportional the amount of time since the candle has been burning.
