Answer:
Yes the inverse of a function does exist. Hope this helps :)
For the answer to the question above,
<span>V(n) = a * b^n, where V(n) shows the value of boat after n years.
V(0) = 3500
V(2) = 2000
n = 0
V(0) = a * b^0 = 3500
a = 3500
V(2) = a * b^2
2000 = 3500 * b^2
b = sqrt (2000/3500)
b ≈ 0.76
V(n) = 3500 * 0.76^n
We can check it for n = 1 which is close to 2500 in the graph:
V(1) = 3500 * (0.76)^1
V(1) = 2660
And in the graph we have V(3) ≈ 1500,
V(n) = 3500 * (0.76)^3 ≈ 1536
Now n = 9.5
V(9.5) = 3500 * (0.76)^(9.5)
V(9.5) ≈ 258</span>
Find the difference between the 2 numbers which will give you the increase from the lower value to the higher. Divide this increase by the original (lower) number and multiply the result by 100 to get the percentage. For us that looks like this:
. Simplifying a bit we have
or 49%, rounded.
The mean of the students scores is 81.3, the median is 80.
If Ms.Mosher adds 5 bonus points to each student, the mean and median will both increase by 5 of the six student’s scores!
Hi there
Payment per year
1,000×12months=12,000
total payment over the lifetime of the loan.
12,000×10years=120,000
Hope it helps
