The simplified expression is \frac{-1}{9x} -9x - 10.

<h3>What is algebraic expression?</h3>

An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.).

Here, the given expression

           \frac{1}{x}+\frac{-10x/9}{x^2}-9x-10

            \frac{1}{x}+\frac{-10}{9x}-9x-10

             \frac{9-10}{9x} -9x -10

                 \frac{-1}{9x} -9x - 10

Thus, the simplified expression is \frac{-1}{9x} -9x - 10.

In 2002, a certain town recorded 15,300 acres of underdeveloped land. Each year
Katyanochek1 [597]

The approximate amount of underdeveloped land in 2013 is A = 15300 X e^-0.07(11).

<h3>How do you determine the future value when there is continuous compounding? </h3>

The formula for calculating future value of an investment when there is continuous compounding is A = P x   e^{r}x N

Where:

  • P = population in 2002
  • r = rate of decrease = 0.07
  • n = number of years = 2013 - 2002 = 11 years

A = 15300 X e^-0.07(11)
