To simplify the expression
Given:
The expression,
Concept Used:
- Like terms are the terms that contain the same variable with similar exponents on it. Constants are like terms as well.
- In any expression, terms are separated by plus or minus signs.
- Coefficients are the constants in front of the variable terms.
Calculation:
In order to simplify the given expression, first open the brackets to expand the expression and then simplify further by combining the like terms as shown below
Thus, the expression is
Now, to write the polynomial in standard form first write the degree of each term and then write the term with higher exponents to lowest exponents and then the constant term as shown below:
The degree of the term
The degree of the term
The degree of the term
The constant term is
So, the standard form is

- 3. We'd like to know the first time when the population reaches 7000 people. First, graph the function from part (a) on your calculator or Desmos. In the same window, graph the line y = 7000. Notice that you will need to adjust your window so that you can see values as big as 7000! Investigate the intersection of the two graphs. (This video shows you how to find the intersection on your calculator, or in Desmos just hover the cursor over the point.) At what value t> 0 does the line intersect with your exponential function? Round your answer to two decimal places. (You don't need to show work for this part.)

The value appreciated to $170,000 by the year 2007. A) If the value is growing exponentially, what was the annual growth rate between 1988 and 2007? Round the growth rate to 4 decimal places. r = B) What is the correct answer to part A written in percentage form? r = 3 %.arrow_forward
