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

What is the value of 2x3 + 4x2 - 3x2 - 6x when x = 3?
never [62]

Answer:

-10

Step-by-step explanation:

If the equation is 2 x 3+4 x 2-3 x 2- 6(x)=  .  Than the equation would turn into  2 x 3+4 x 2-3 x 2- 6(3) which equals -10.

2. Define the absolute value function, y = |x|, as a piecewise function. Please include complete sentences and examples to justi
Mekhanik [1.2K]
Y = |x| = x if x ≥ 0, -x if x < 0

absolute value can be interpreted as a function that does not allow negative real numbers, forcing them to be positive (leaving 0 alone). if the input x is more than or equal 0, then x stays positive so there is no need to do anything: "x if x ≥ 0".
if the input is less than 0, then it is an negative number and needs a negative coefficient to negate the negative: "-x if x < 0"

example: if x = -3, then it will take the "-x if x < 0" piece resulting in y = -(-3) = 3, which is what |-3| does

if x = 1, it will take the "x if x ≥ 0" piece and just have y = 1 which is what |1| does.

for x = 0, it will take the "x if x ≥ 0" and just have y = 0 which is what |0| does

Three friends each have some ribbon. Carol has 54 inches of ribbon, Tino has 7.5 feet of ribbon, and Baxter has 3.5 yards of rib
Nastasia [14]
1 ft = 12 inches......1 yd = 36 inches

carol has 54 inches
Tino has 7.5 ft......7.5 * 12 = 90 inches
baxter has 3.5 yds......3.5 * 36 = 126 inches
for a total of : (54 + 90 + 126) = 270 inches total <===

1 ft = 12 inches....so 270 inches = 270/12 = 22.5 ft <==
1 yd = 36 inches..so 270 inches = 270/36 = 7.5 yds <==
