The answer to this problem is 10x - 1 with a 5 reminder, which can also be written as 10x - 1 + 5/(x + 10).
To find this, we first have to turn it into a long division problem. First we look to see how many times x goes into 10x^2.
10x^2/x = 10x.
Now we eliminate the first term and multiply the 10x by the second term.
10x * 10 = 100x.
We now subtract that 100x from 99x. This gives us a -x remainder. We can now see how many times x goes into that as well.
-x/x = -1
This gives us the final answer of 10x - 1 with a 5 remainder.
Formula of the daily compound interest:
A = P.e^(r.t), where P is the initial investment, r = interest rate, t = number of years e= 2.718 and A = final amount
6,225.18= 4,543.11(e)^(r.15)
(e)^(r.15) = 6,225.18/4,543.11
(e)^(r.15) = 1.3702046
ln[(e)^(r.15)] = ln(1.3702046)
15.r = 0.314991
And r = 0.314491/15 = 0.020 OR 2%
