For each of the following, determine the interest rate per compounding period. 1) 12% per year, compounded weekly b) 8% per year
Zarrin [17]

Using compound interest, the rates per compounding period are given as follows:

a) 0.1273 = 12.73%.

b) 0.0833 = 8.33%

c) 0.0617 = 6.17%

<h3>What is compound interest?</h3>

The amount of money earned, in compound interest, after t years, is given by:

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

In which:

  • 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.

The <u>interest rate per compounding period</u> is given as follows:

\left(1 + \frac{r}{n}\right)^n - 1

For item a, the parameters are:

r = 0.12, n = 52.

Hence:

\left(1 + \frac{0.12}{52}\right)^{52} - 1 = 0.1273

For item b, the parameters are:

r = 0.08, n = 104.

Hence:

\left(1 + \frac{0.08}{104}\right)^{104} - 1 = 0.0833

For item c, the parameters are:

r = 0.06, n = 12.

Hence:

\left(1 + \frac{0.06}{12}\right)^{12} - 1 = 0.0617

A swimming pool has a length of 28 feet, a width of 16 feet, and a depth of 7 feet.
ivanzaharov [21]

Answer:

The pool can hold 3,136 cubic feet of water

Step-by-step explanation:

To know how much water the pool can hold,  we need to find the volume of this swimming pool, because the volume is how much a container can hold.

The formula for volume is L*W*H (length times width times height)

Let's multiply!

28*16*7=3136
