A 11-inch candle is lit and burns at a constant rate of 1.3 inches per hour. Let t represent the number of hours since the candle was lit, and suppose R is a function such that R(t) represents the remaining length of the candle (in inches) t hours after it was lit. a. Write a function formula for R in terms of t. R(t)=11-1.3t Preview b. What is the domain of R relative to this context? Enter your answer as an interval. [0,8.46] Preview c. What is the range of R relative to this context? Enter your answer as an interval. Preview no answer given d. What is the domain of R¯ relative to this context? Enter your answer as an interval. Preview e. What is the range of R' relative to this context? Enter your answer as an interval. Preview f. Solve R(t) = 6.2 for t. t = 3.69 Preview g. What does your solution in part (f) represent in this context? Select all that apply. How many hours since the candle was lit when it is 6.2 inches long. * The length of the candle (in inches) 6.2 hours after it was lit. How long it takes for the candle to burn out.
