Answer:

$\frac{1}{ \sqrt[7]{ {12}^{4} } }$

Step-by-step explanation:

${12}^{ - \frac{4}{7} } is \: the \: same \: as \\ \frac{1}{ {12}^{ \frac{4}{7} } } \\ {12}^{ \frac{4}{7} } can \: also \: be \: expressed \: as \\ \sqrt[7]{ {12}^{4} }$

Therefore:

${12} ^ { -\frac{4}{7} } \: is \: equivalent \: to \\ \frac{1}{ \sqrt[7]{ {12}^{4} } }$

Suppose you deposited $900 into an account that earns 4% simple annual interest. Find the balance of the account after 6 months

Jet001 [13]

Balance after 6 months would be 900*(900+2%). You just need to evaluate it then you will get the answer. btw 2% comes from 4% because it's half of the year.

Suppose that $3000 is placed in an account that pays 16% interest compounded each year. Assume that no withdrawals are made from

Papessa [141]

Answer:

a) $3480

b) $4036.8

Step-by-step explanation:

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.

Suppose that $3000 is placed in an account that pays 16% interest compounded each year.

This means, respectively, that $P = 3000, r = 0.16, n = 1$
