Answer: 4,676.96Procedure:The formula for compounded interest is:

Future value = investment * factor
Interests = future value - investment
Where r is the monthly rate, which you calculate as the % yearly rate divided by 12.
And n is the number of months which is equal to the number of years times 12.
These are the calculations:



Future value = 3080.43 *2.518 = 7,757.39
Interests = 7,757.39 - 3080.43 = 4,676.96
Answer:
1000 rounded to the nearest ten is:
1000
Step-by-step explanation:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
Given that f(x) = 2x + 11: if f(x) = y = 21, then 21 = 2x + 11, and so 10=2x and x=5.
Thus, f(5) = 2(5) + 11 = 21; (5,21) is a point on the graph of f(x).
If that is so (which it is), then (21,5) is a point on the graph of the inverse function, and 5 is the appropriate output value.
