When Maddy was born, her aunt opened a certificate of deposit in her
Lostsunrise [7]

Given the final amount of money available in Maddy's account, the interest rate and the time elapsed, the initial money her aunt invested was $15,000.

<h3>What is an interest in banking?</h3>

Interest is simply the amount of money a lender or financial institution receives for lending out money or pays for receiving money.

The formular for calculating compound interest is expressed as;

A = P(1 + r/n)^(n*t)

Where A is final amount, P is initial principal balance, r is interest rate, n is  number of times interest applied per time period and t is number of time periods elapsed.

Given the data in the question;

  • Interest rate r = 5.5% anuually = 5.5/100 = 0.055
  • Final amount A = $39,322
  • Time r = 18 yrs
  • Initial principal balance P = ?

We substitute our given values into the expression above.

$39322  = P(1 + 0.055/1)^(1*18)

$39322  = P(1 + 0.055)^(18)

$39322  = P(1.055)^(18)

P = $39322 / (1.055)^(18)

P = $39322 / 2.621466

P = $15,000

Therefore, given the final amount of money available in Maddy's account, the interest rate and the time elapsed, the initial money her aunt invested was $15,000.

Step-by-step explanation:

In this question, the above given-choice is correct because the account on the same bank has certainly, but when a retirement fund in a company is concerned, you could only have a savings account on their behalf, and the mutual funds must then be distributed, and these several savings accounts can be opened is by tracking the amount they need to save for every savings target.

Calculate the area under the graph of f(x) = 1/xlnx from x = e to x = e^e
Gnom [1K]

Using integration, it is found that the area under the graph of f(x) in the desired interval is of 1 unit squared.

<h3>How is the area under a graph found?</h3>

The area under the graph of a curve f(x) between x = a and x = b is given by the following integral:

A = \int_{a}^{b} f(x) dx

In this problem, the function and the limits of integration are given by:

f(x) = \frac{1}{x\ln{x}}

a = e, b = e^e

Hence:

A = \int_{e}^{e^e} \frac{1}{x\ln{x}} dx

Using substitution:

u = \ln{x}

du = \frac{1}{x} dx

dx = x du

Hence:

\int \frac{1}{x\ln{x}} dx = \int \frac{1}{u} du = \ln{u} = \ln{\ln{x}}

Applying the Fundamental Theorem of Calculus:

A = \ln{\ln{e^e}} - \ln{\ln{e}} = \ln{e\ln{e}} = \ln{\ln{e}} = \ln{e} - \ln{1} = 1

Hence, the area under the graph of f(x) in the desired interval is of 1 unit squared.
