⦁ A $10,000 certificate of deposit earns simple interest of 8 percent per year. Calculate the total earned money over the 5 year
abruzzese [7]

Answer:

The total earned money over the 5 year period=$14,000

Step-by-step explanation:

We are given that

Principle amount, P=$10000

Rate of interest, r=8%

Time, t=5 years

We have to find the total earned money over the 5 year period.

We know that

Simple interest=\frac{P\times r\times t}{100}

Using the formula

S.I=[tex]\frac{10000\times 8\times 5}{100}{/tex]

S.I=$4000

Now,

Amount=P+S.I

Amount=10000+4000

Amount=$14000

Hence, the total earned money over the 5 year period=$14000

Given the definitions of f (x) and g(x) below, find the value of (g • f)(9).
Stells [14]

9514 1404 393

Answer:

  (g·f)(9) = 496

Step-by-step explanation:

One way to do this is to find the values of g(9) and f(9).

  g(9) = (3x -1)x +14 = (3(9) -1)(9) +14 = 26(9) +14 = 248

  f(9) = -(9) +11 = 2

Then ...

  (g·f)(9) = g(9)·f(9) = 248·2

  (g·f)(9) = 496

(3x^4y^5) ^ 3/7 in radical form
kobusy [5.1K]

The expression in radical form is (\sqrt[7]{3x^4y^5}) ^3

In order to express the given indices expression in radical form, we need to ensure there is a square root present in the resulting expression.

According to the law of indices,

a^{m/n} = \sqrt[n]{m}

Given the indices (3x^4y^5) ^ {3/7}

Comparing with the general formula, we will see that:

m = 3

n = 7

a = 3x^4y^5

Applying the law of indices:

(3x^4y^5) ^ {3/7} = (\sqrt[7]{3x^4y^5}) ^3

Hence the expression in radical form is (\sqrt[7]{3x^4y^5}) ^3
