Answer:
sum = ∑[n=1,5] 4^(n-4)
Step-by-step explanation:
First of all, you need to be able to describe the n-th term.
Here, we have ...
term #: 1, 2, 3, 4, 5
value: 4^-3, 4^-2, 4^-1, 4^0, 4^1
That is, the exponent of 4 is 4 less than the term number. So, the n-th term is 4^(n-4). The sum of the 5 terms shown is then ...

The generic equation of the line is:

Where,
m: slope of the line
(T0, H0): ordered pair belonging to the line.
The slope of the line is:

Substituting values we have:

Rewriting:


Then, choosing an ordered pair we have:

Substituting values we have:

Rewriting the equation:

Then, for 8 hours we have:
Answer:
a linear equation to model the relationship between height H of the candle, and T time is:
the candle will be 12 inches after burning 8 hours
