Don't forget your Algebra I now that you're taking calculus.
You have two points: (5,26.5) and (24,24.6)
So figure the slope of the line, and use the point-slope form of the equation.
Then find f(11)
Or, just do linear interpolation.
11 is 6/19 of the way from 5 to 24
so, the height will be 6/19 of the way from 26.5 to 24.6
Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. After 5 hours of burning, a candle has a height of 26.5 centimeters. After 24 hours of burning, its height is 24.6 centimeters. What is the height of the candle after 11 hours?
