The answer to the given question is as below:-
Polynomials:-
x³-7x²+9x-5x⁴-20
x⁵-5x⁴+4x³+2x-1
3x²-5x⁴+2x-12
Non-polynomial:-
x⁻5-5x⁻⁴+4x⁻³+2x⁻1-1
<h3>What are polynomials?</h3>
A polynomial is a mathematical equation made up of indeterminates and coefficients and involves only addition, subtraction, multiplication, and non-negative integer exponentiation of variables. The exponents of the polynomials can not be irrational.
So the table will be formed as:-
Polynomials:- Non-polynomial:-
x³-7x²+9x-5x⁴-20 x⁻5-5x⁻⁴+4x⁻³+2x⁻1-1
x⁵-5x⁴+4x³+2x-1
3x²-5x⁴+2x-12
Therefore the polynomials and non-polynomials are shown in the table above.

Answer:
Step-by-step explanation:
<h3> <em><u>The complete exercise is: "At the cocession stand, medium sodas cost $1.25 and hot dogs cost $2.50. Jack bought 2 medium sodas snd 2 hot dogs. He paid with $20. What was his change?"</u></em></h3>
You need to analize the information provided in the exercise.
You know that the price of a medium soda was:
And the price of a hot dog was:
Therefore the total amount of money Jack spent in 2 medium sodas and 2 hot dogs, was:
Since Jack paid with $20, you need to subtract the total amount of money calculated before from $20, in order to calculate his change.
Therefore, you get that Jack's change was:
<h3>
Answer:</h3>
99.90%
<h3>
Step-by-step explanation:</h3>
STEPS:
- Find the total amount
- Find out what number of what we want to know the percentage of there are out of the whole amount there is. (Divide the percentage amount we want to find by the total amount)
- Turn into a percentage by multiplying by 100
Find the total sum
30.2 mil = 30,200,000 small businesses + 30,000 other = 30,230,000 total
Find the fraction that small businesses make up of the total
Convert to percentage
0.9990 → % = 0.9990 × 100 = 99.90%

The distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
Speed = 72 km/h
time = 45 mins = 45/60 = 0.75 hours
We know,
Distance = Speed×time
Distance = 72(km/h)×0.75(h)
Distance = 54 km
Thus, the distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.
