Find the interest generated if one invests $6000 for 9 years at 7% per annum with interest compounded monthly
Answers
Answer:
$5,245.06 (nearest cent)
Step-by-step explanation:
Compound Interest Formula
[tex]\large \text{$ \sf I=P\left(1+\frac{r}{n}\right)^{nt} -P$}[/tex]
where:
I = interest accruedP = principal amountr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsedGiven:
P = $6,000r = 7% = 0.07n = 12 (monthly)t = 9 yearsSubstitute the given values into the formula and solve for I:
[tex]\implies \sf I=6000\left(1+\dfrac{0.07}{12}\right)^{12 \times 9}-6000[/tex]
[tex]\implies \sf I=6000\left(\dfrac{1207}{1200}\right)^{108}-6000[/tex]
[tex]\implies \sf I=5245.061831...[/tex]
Therefore, the interest generated is $5,245.06 (nearest cent).

Answers
Answer:
there are infinite values of sum X + Y = (Y + 65/Y) since there are infinite values of Y.
Step-by-step explanation:
XY = 65. Given that question is asking you find X + Y, it kind of indicates that there could be very limited possible values of X and Y which you can work out. Again it is an indication of such silly questions. It need not be true that you have limited solutions.
One such solution is represented here. I have assumed X and Y are positive integers only.
Factorize 65 = 65 x 1 or 13 x 5
Therefore (X,Y) can be (65,1) or (13,5) .
So X + Y = 66 or 18.
If we include negative integers as well ,
then XY = 65 => Factors are 65 x 1, 13 x 5 or (-13) x (-5) or (-65) x (-1)
So X + Y = -66 or -18 or 18 or 66.
In general,
XY = 65 => X = 65/Y (assuming Y is not 0 else XY would have been 0 too).
Therefore X + Y = Y + 65/Y.
If X, Y belong to real or complex numbers except 0,
there are infinite values of sum X + Y = (Y + 65/Y) since there are infinite values of Y.
