Answer:A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x² = −1. Because no real number satisfies this equation, i is called an imaginary number.

A promissory note for $3600.00 dated May 15, 2012, requires an interest payment of $370.00 at maturity. If interest is at 9.6% c
vladimir1956 [14]

The due date of the promissory note is May 24th 2013.

Data;

  • Present Value (PV) = $3600
  • Interest = $370
  • Future Value (FV) = PV + I = $3600 + $370 = $3970

<h3>Due Date of the Note</h3>

To calculate the due date of the note, we can use the formula of future value of the note.

FV = PV (1 + \frac{r}{n})^d\\ 3970 = 3600 (1 + \frac{9.6}{12})^d\\3970 = 3600(1+0.008)^d\\\frac{3970}{3600} =(1.008)^n

Let's take the natural log of both sides

(1.008)^n = (\frac{3970}{3600})\\ n\ln(1.008) = \ln(\frac{397}{360})\\ n = 12.28

This is approximately 12 months and 9 days.

The due date of the promissory note is May 24th 2013.
