Basically meaning that no model can exactly be on point with whatever it is modeling. Two things cannot be EXACTLY identical to what they are referring to, but it is saying that some can get close enough to be useful as an example.
Answer:
25%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
Here, new number = 30, and old number = 24.
percent change = (30 - 24)/(24) * 100%
percent change = 6/24 * 100%
percent change = 0.25 * 100%
percent change = 25%
Laptop's sale tax
=6/100 x 650
=39
Power adapter's sale tax
=6/100 x 59
=3.54
Total Sales tax=
39+3.54
=42.54

Answer:
A Polynomial can be expressed in terms that only have positive integer exponents and the operations of addition, subtraction, and multiplication. In other words, it must be possible to write the expression without division.
Step-by-step explanation:
<em>EXAMPLES :</em>
- <em> x2 + 2x +5 Since all of the variables have integer exponents that are positive this is a polynomial.</em>
- <em>5x +1 Since all of the variables have integer exponents that are positive this is a polynomial.</em>
- <em>(x7 + 2x4 - 5) * 3x Since all of the variables have integer exponents that are positive this is a polynomial.</em>
- <em>5x-2 +1 Not a polynomial because a term has a negative exponent</em>
- <em>3x½ +2 Not a polynomial because a term has a fraction exponent</em>
- <em>(5x +1) ÷ (3x) Not a polynomial because of the division</em>
- <em>(6x2 +3x) ÷ (3x) Is actually a polynomial because it's possible to simplify this to 3x + 1 --which of course satisfies the requirements of a polynomial. (Remember the definition states that the expression 'can' be expressed using addition,subtraction, multiplication. So, if it's possible to simplify an expression into a form that uses only those operations and whose exponents are all positive integers...then you do indeed have a polynomial equation)
