Answer:
16,000
Step-by-step explanation:
20,000 x .20 = 4,000
20,000 - 4,000 = 16,000
By looking at the degree of the polynomials, we conclude that the option that is not linear is option C.
<h3>Which of the following functions is not a linear function?</h3>
A polynomial is an expression of the form:

Where all the exponents are natural numbers.
We define the degree of a polynomial as the largest exponent, and we define a linear function as a polynomial of degree 1.
So a linear function is of the form:

Now, if you look at option C, you can see that the degree of that polynomial is 2. So that is not a linear function.
Then the correct option is C.

Using the Factor Theorem, the polynomial is given by: 
- The graph is sketched at the end of the answer.
The <em>Factor Theorem</em> states that a polynomial function with roots
is given by:
In which a is the leading coefficient.
In this problem, the roots are:
- Root of -4 with multiplicity 4, hence
.
- Root of -1 with multiplicity 3, hence
.
- Root of 5 with multiplicity 6, hence

Then:


- Positive leading coefficient, hence
.
- 13th degree, so it is odd.
Then:

At the end of the answer, an sketch of the graph is given.

Although a radical cannot be expressed as a terminating or recurring decimal or a fraction, it can be approximated. This approximation can be expressed as a decimal or a fraction. So if a decimal, ordinary rules of arithmetic apply.
If a fraction, ordinary rules for subtracting fractions apply.
EXAMPLE
99/70 is a good approximation for √2. Let’s see how we would calculate 5-√2=5-99/70=(350-99)/70=251/70=3⁴¹⁄₇₀.
√2=1.4142 to 4 places of decimals. So 5-√2=5-1.4142=3.5858. When we work out 3⁴¹⁄₇₀ as a decimal to 4 places we get 3.5857.
So treat radicals like other real numbers. When giving an answer you may need to say what accuracy you are using (so many decimal places) or the question may tell you how many decimal places are needed.
Matt will be different because he is basically free handing it and everyone has human errors. but since she is using the technology she shouldn't mess up.
