By analyzing the polynomial we have the following conclusions about the five propositions:

1) True

2) True

3) False

4) False

5) True

In this question we have a second order polynomial with two variables (x, y) and we need to determine the truth value of each proposition by applying concepts related to polynomials.:

1) There are four terms - A term is an additive component of the polynomial. Thus, the polynomial has four terms. (True)

2) 6 · x² and 3 · x are like terms - Two components are like terms if they have the same variable. Thus, 6 · x² and 3 · x are like terms. (True)

3) The coefficient on y is 14 - A coefficient is a constant that accompanies a variable. The constant of y is -14. (False)

4) Simplified, the expression is 6 · x² + 5 · x - 14 · y - The simplification of the polynomial is done by applying algebraic properties. The simplified form is 6 · x² + x - 14 · y. (False)

5) The commutative property allows the expression to be written as 6 · x²  - 14 · y + 3 · x - 2 · x - Commutative property indicates that the order of components of the polynomial can be changed without changing the result of the entire polynomial. (True)

The statement is incomplete and incorrectly formatted. Correct statement is shown below:

Determine the truth value of each statement based on the expression 6 · x² - 2 · x - 14 · y + 3 · x.

1) There are four terms.

2) 6 · x² and 3 · x are like terms.

3) The coefficient on y is 14.

4) Simplified, the expression is 6 · x² + 5 · x - 14 · y.

5) The commutative property allows the expression to be written as 6 · x²  - 14 · y + 3 · x - 2 · x.

The probability that the number is not a prime number is 5/9.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Paul is thinking of a number that is greater than 10 and less than 20.

So, the prime number between 10 and 20 are 11, 13, 17, 19.

So, the probability that the number is not a prime number

= ( 9- 4)/ 9

= 5/9

Hence, the probability that the number is not a prime number is 5/9.

Convex polygon

A polygon is a figure that has no curved lines. A convex polygons has no "caves."

In this instance, answer choices B, C, and D all have curved lines which means that they aren't polygons. Additionally, as an example of a concave polygon, answer choice D creates a sort of "cave."

Therefore, answer choice A is a convex polygon.

Step-by-step explanation:

To find extreme values, take the first derivative

[tex]y = - 3 {x}^{2} + 16x - 16[/tex]

Solve the equation for x.

[tex]x = \frac{ - 16 + \sqrt{256 - 192} }{ - 6} [/tex]

or

[tex]x = \frac{ - 16 - \sqrt{256 - 192} }{ - 6} [/tex]

[tex]x = \frac{ - 16 + \sqrt{64} }{ - 6} [/tex]

or

[tex]x = \frac{ - 16 - \sqrt{64} }{ - 6} [/tex]

We then get

[tex]x = \frac{4}{3} [/tex]

or

[tex]x = 4[/tex]

So our extreme values occur at x=4/3 and x=4

Zeroes:

[tex] - {x}^{3} + 8 {x}^{2} - 16x[/tex]

[tex] - x( {x}^{2} - 8x + 16)[/tex]

[tex] - x(x - 4) {}^{2} [/tex]

[tex] - x = 0[/tex]

[tex](x - 4) {}^{2} = 0[/tex]

[tex]x = 4[/tex]

So we have a double root at 4, and a root of 0. We have two positive roots and one non negative root

End behavior:

Since we have a negative leading coefficient and a odd degree, as x becomes more positive, y will become negative and as x becomes more negative, y will become positive.

Answer:

0.035 grams

Step-by-step explanation:

Grams of salt per gram of ocean water

For every gram of ocean water, there is 0.035 grams of salt dissolved in it.

The salinity of earths oceans,

→ a = 525 g

Amount of water for the salinity,

→ b = 15 kg

→ b = 15 × 1000

→ [ b = 15000 g ]

Then find the grams of salt for every gram of ocean water,

→ a ÷ b

→ 525 ÷ 15000

→ 0.035 g

Hence, answer is 0.035 grams of salt.

Answer: 8y

Step-by-step explanation:

The values needed to find the length AB will be;

⇒ AB = √(3x)² + (- 8y)²

Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.

Given that;

The coordinate are,

⇒ A = (- 5x, 4y)

⇒ B = (- 2x, - 4y)

Now,

Since, We know that;

The distance between the points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

So, The distance between the points (- 5x, 4y) and (- 2x, - 4y) is,

⇒ d = √ (- 2x - (- 5x))² + (- 4y - 4y)²

⇒ d = √(3x)² + (- 8y)²

Thus, The values needed to find the length AB is find as;

⇒ AB = √(3x)² + (- 8y)²

Step-by-step explanation:

The statement first, statement second, and statement sixth are true.

It is defined as a three-dimensional space enclosed by an object or thing.

We have:

The original prism has a length of 3 inches, a width of 2 inches, and a height of 1 inches.

The new length = 3+2 = 5 inches

The new width = 2+2 = 4 inches

The new height = 1+2 = 3 inches

The volume of the old prism  = 3×2×1 = 6 cubic inches

The volume of the new prism = 5×4×3 = 60 cubic inches

Srekar, could increase the volume by the same amount by just adding 6 to the height instead of 2 to each side is false becasue:

Volume = 3×2×(1+6) = 42 cubic inches

The volume of the new prism will be 20 times 3 = 60 because there will be 20 cubes in each layer and the height will be 3 so there will be 3 layers of 20 cubes each is true.

Thus, the statement first, statement second, and statement sixth are true.

The percentage of pies sold that were apples or cherry is 52%

The given parameters are:

The total number of pies is:

Total = 32 + 33 + 20 + 15

Evaluate

Total = 100

The percentage of apples or cherry is calculated as:

Percentage = (Apple + Cherry)/Total

So, we have:

Percentage = (32 + 20)/100

Evaluate the quotient

Percentage = 0.52

Express as percentage

Percentage = 52%
