Answer:
Step-by-step explanation:
For this case we need to define some notation:
represent the remaining length of the candle in inches
represent the time in hours that have elapsed since the candle was lit.
For this case we assume that L and f are related so then we can write this like that: L is a function of t.
And for this case we have a constant rate given of:
And we know a initial condition
So then since we have a constant rate of change we can use a linear model given by:
Where m is given and we need to find b. If we use the initial condition we have this:
And solving for b we got:
So then our lineal model would be given by:
