Cooper invested $3,100 in an account paying an interest rate of 2%

Liula [17]

Answer:

Robert will have $481 more in his account than Cooper.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Continuous compounding:

Similar to compound interest:

$A(t) = P(1 + r)^t$

Cooper:

Cooper invested $3,100 in an account paying an interest rate of 2% compounded quarterly. This means that $P = 3100, r = 0.02, n = 4$

After 12 years is A(12). So

$A(t) = P(1 + \frac{r}{n})^{nt}$

$A(12) = 3100(1 + \frac{0.02}{4})^{4*12}$

$A(12) = 3938.5$

Cooper will have $3938.5 in his account.

Robert:

Robert invested $3,100 in an account paying an interest rate of 3 % compounded continuously. So $P = 3100, r = 0.03$ .

After 12 years.

$A(t) = P(1 + r)^t$

$A(12) = 3100(1 + 0.03)^{12}$

$A(12) = 4419.9$

Robert will have $4419.9 in his account.

How much more money would Robert have in his account than Cooper, to the nearest dollar?

4419.9 - 3938.5 = 481.4

To the nearest dollar, Robert will have $481 more in his account than Cooper.

The following is a subset of A = {1, 2, 3, 4, 5}, except: *

erica [24]

A subset only includes element from the original set.

Answer #3 has "7" in it, but 7 isn't in Set A, so it cannot be a subset.

HELP!!pls solve this rn pls. pls i rly need it now<br> 5 (-2a – 8 ) < -9a +4

Ann [662]

5(-2a-8) < -9a + 4

Use distributive property on left side:

-10a -40 < -9a + 4

Add 40 to both sides

-10a < -9a + 44

Add 9a to both sides

-a < 44

Multiply both sides by -1 and reverse the inequality sign:

A > -44

Answer: a > -44

3^-6x(3^3 divide 3^0)^2

Greeley [361]

Answer:

${3}^{2}$

Step-by-step explanation:

$3^{ - 6} \times (3^4 \div 3^0)^2$

$\frac{1}{ {3}^{6} } \times ( {3}^{4} \div {3}^{0} {)}^{2}$

$\frac{1}{729} \times ( {3}^{4} \div {3}^{0} {)}^{2}$

$\frac{1}{729} \times ( {3}^{4} {)}^{2}$

$\frac{1}{729} \times 6561$

$\frac{1}{729} \times (729(9))$

$9$

${3}^{2}$
