If $2940 is invested at 3.2% compounded quarterly, how much is in the account after 8 years?

tino4ka555 [31]

Answer:

The future value is $3793.776

Step-by-step explanation:

Given

$PV = 2940$ --- present value

$r = 3.2\%$ --- rate

$t = 8$ --- time

$n = 4$ --- quarterly

Required

Determine the future value

This is calculated using:

$FV = PV(1 + \frac{r}{n})^{nt$

So, we have:

$FV =2940 * (1 + \frac{3.2\%}{4})^{4*8$

$FV =2940 * (1 + \frac{3.2}{400})^{32$

$FV =2940 * (1 + 0.008)^{32$

$FV =2940 * (1.008)^{32$

$FV =2940 * 1.2904$

$FV =3793.776$

Write the recursive rule and the iterative rule for the following sequence: 10, 6, 2, -2, -6

barxatty [35]

The recursive rule is
$a_n=a_{n-1}+(-4)$ .
The iterative rule is
$a_n=14-4n$

The recursive rule is given by the formula
$a_n=a_{n-1}+d$ , where d is the common difference. Our common difference is -4, which gives us the recursive rule above.

The iterative rule begins with the formula
$a_n=a_1+d(n-1)$ , where a₁ is the first term and d is the common difference. Our first term is 10 and our common difference is -4:
$a_n=10+(-4)(n-1)
\\\text{Using the Distributive Property,}
\\
\\a_n=10+(-4*n)+(-4*-1)
\\
\\a_n=10-4n+4
\\
\\\text{Combining like terms,}
\\
\\a_n=14-4n$

I need the RIGHT answer to this please. :)

KATRIN_1 [288]

A is the answer. It has no repeating x points buy it repeats on the y coordinate, which is okay. The answer is A just to say it again.

lukranit [14]

Answer:

Step-by-step explanation:

The slope of line u is 9/2; the line perpendicular to that is the opposite reciprocal...opposite sign and the flip of the fraction. The perpendicular slope is -2/9
