determine whether the following statements are true and give an explanation or counterexample. a. all polynomials are rational functions but not all rational functions are polynomials.
The given statement: " all polynomials are rational functions but not all rational functions are polynomials." is true; its counterexample will be: Not all polynomials are rational functions but all rational functions are polynomials.
What is a polynomial?Polynomial refers to an algebraic equation that has more than two terms, particularly the accumulation of numerous phrases that each include a different power of the same variable (s).
Now,
A polynomial of degree n has at most n real zeros. The degree of a polynomial function determines the end behavior of its graph. A rational function is a function of the form: [tex]f(x)=\frac{P(x)}{Q(x)}, Q(x) \neq 0[/tex] and P(x) and Q(x) are both polynomials.A function that cannot be written in the form of a polynomial is not a rational function.Further,
A counterexample refers to an idea or a statement that contradicts an idea or a theory.Basically, we can infer that it is the negation of a statement.For the given statement, the negation would be given as: Not all polynomials are rational functions but all rational functions are polynomials.Hence, The given statement: " all polynomials are rational functions but not all rational functions are polynomials." is true; its counterexample will be: Not all polynomials are rational functions but all rational functions are polynomials.

Trina wants to find the least expensive way to buy 24 necklaces. She wants to buy only one type of package. She has $48. The table shows the number of necklaces in a package and the cost of each package.
Trina should buy the $6 packages to get 24 necklaces for the least price as calculated by using multiplication and division.
A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics .One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division. The other operations are multiplication, addition, and subtraction.At a fundamental level, counting the instances in which one number is included within another is one interpretation of the division of two natural numbers.From the attached table let us calculate the cost of buying necklaces in the various packages by using multiplication and division.
For the $4 package:
Number of necklaces in the package = 3
Number of packages Trina should buy (division used) = 24 ÷ 3 = 8
Cost of 8 packages =$ 4 × 8 = $ 32
For the $5 package:
Number of necklaces in the package = 4
Number of packages Trina should buy(division used) = 24 ÷ 4 = 6
Cost of 8 packages =$ 5 × 6 = $ 30
For the $6 package:
Number of necklaces in the package = 6
Number of packages Trina should buy(division used) = 24 ÷ 6 = 4
Cost of 8 packages =$ 6 × 4 = $ 24
Therefore buying the $24 package is the cheapest.

A customer wanted to purchase a video game and realized that they were short $3.96 to be able to pay. Which value is the opposite of being short $3.96?
Using the absolute value function, the value that is the opposite of being short $3.96 is: x + 3.96.
What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, that is, |2| = |-2| = 2.
For this problem, the number is of $3.96, that is:
|x| = 3.96.
Hence:
Short of $3.96 means that x = -3.96.The opposite is the other solution, of x = 3.96.More can be learned about the absolute value function at https://brainly.com/question/24734454

which lines are parallel
y=2x+3
y=2x-5
y=-2x+3
The parallel lines are y = 2x + 3 and y = 2x - 5
How to determine the parallel lines?The given equations are linear equations
Linear equations are represented as
y = mx + c
Where the slope of the linear equation is
Slope = m
Linear equations that have the same slope are parallel
This means that y = mx + c and y = mx + b are parallel lines because the slopes of the linear equations is m
Using the above as a guide, the parallel lines are y = 2x + 3 and y = 2x - 5

The circle below is centered at (4,-1) and has a radius of 3. What is it’s equation?
The equation of the area of the circle (x - 4)^2 + (y + 1)^2 = 9, that is, option B.
The standard form of an equation of a circle is (x - h)^2 + (y - k)^2 = r^2
where, r = radius of the circle and (h, k) are the coordinates of the center of the circle.
Here, we are given that a circle is centered at (4,-1) and has a radius of 3.
Thus, r = 3
h = 4
and k = -1
Therefore, the equation of the circles will be-
(x - 4)^2 + (y - (-1))^2 = 3^2
(x - 4)^2 + (y + 1)^2 = 9
Thus, option B, (x - 4)^2 + (y + 1)^2 = 9 is the correct option.

Given that the variable y varies directly with the variable x. If the value of x is 14, the value of y will be 21.
If the value of x is 14, what is the value of y?Proportional relationships are relationships between two variables where their ratios are equivalent.
A direct variation is expressed;
a ∝ b then a = kb
Where k is the proportionality constant.
Given the data in the question
a = 10b = 15k = ?First, we determine the proportionality constant.
a = kb
15 = k × 10
k = 15/10
k = 3/2

Answer:
Value of y is 21, when x is 14.
Step-by-step explanation:
Now we have to,
→ find the value of y when x is 14.
Forming the formula,
→ k × 2 = x
→ k × 3 = y
Let's complete the given table,
→ k × 2 = x, k × 3 = y
→ 1 × 2 = 2, 1 × 3 = 3
→ 2 × 2 = 4, 2 × 3 = 6
→ 3 × 2 = 6, 3 × 3 = 9
→ 4 × 2 = 8, 4 × 3 = 12
→ 5 × 2 = 10, 5 × 3 = 15
→ 6 × 2 = 12, 6 × 3 = 18
→ 7 × 2 = 14, 7 × 3 = 21
Then the table will look like,
|| x || y |||| 2 || 3 |||| 10 || 15 |||| 14 || 21 ||Hence, y is 21 when x is 14.

What on a graph is a parabola?
Drawing a parabola for the quadratic function f(x) = ax2 + bx + c results in a U-shaped curve. When an is smaller than zero, the parabola's graph is downward (or opens downward). When the value of an is greater than 0, the parabola's graph ascends (or opens up).Parabola equation with a vertex at (h, k) is given by y = a(x - h)^2 + k
For the give parabola, y = a(x - 4)^2 - 3
y = a(x^2 - 8x + 16) - 3
At (5, -6)
-6 = a((5)^2 - 8(5) + 16) - 3 = a(25 - 40 + 16) - 3 = a - 3
a = -6 + 3 = -3
Therefore, the coefficient of the squared expression is -3..

How to find the nth term in the sequence
3,6,9,12
The n th term of the series is 3n where n is the term of reference
As we can see that there is constant difference in the terms
12-9=3
9-6=3
6-3=3
We are made sure that it is the arithmetic progression
Common difference is the difference that is constantly subtracted or added to each term after the first term
Thus the common difference 'd' is 3 as per the calculations above
Now the first term is 3
We know that any N th term of arithmetic progression is given by the formula
Tn= a+ (n-1)*d
where a is the first term of the progression and n is the term of reference and d is the common difference
a=3
d=3
Therefore, nth term of the series is = Tn= 3 + (n-1) *3
Tn= 3+3n-3
Tn = 3n
Hence the n th term of the series is 3n where n is the term of reference
