A: An example of third-degree polynomial in standard form are 3x^3 - 2x + 5.

B: According to the closure property of addition of polynomials if two polynomials are added then the result is also a polynomial.

A: To create a third-degree polynomial in standard form, we need to have an expression of the form:

ax^3 + bx^2 + cx + d, where a, b, c, and d are constants.

The degree of the polynomial is the highest power of x in the expression, which in this case is 3. To ensure that the polynomial is in standard form, we need to arrange the terms in descending order of their degrees. So, the third-degree term comes first, followed by the second-degree term, then the first-degree term, and finally the constant term.

For example, the polynomial 3x^3 - 2x + 5 is in standard form because the terms are arranged in descending order of degree.

B: The closure property of addition of polynomials states that if we add two polynomials, the result is also a polynomial. In other words, the set of polynomials is closed under addition. This means that if we add any two polynomials, the sum will always be a polynomial.

For example, if we add the polynomials 2x^2 + 3x + 1 and x^3 - 2x^2 + 4, we get a new polynomial  x^3 - x^2 + 3x + 5, which is also a polynomial. Therefore, the closure property ensures that the addition of polynomials is a valid operation.

slope -intercept form       y =  - 3x - 7

slope m =-3 and y - intercept c = -7

Step-by-step explanation:

Explanation:-

Given that slope 'm' = -3 and point (0,-7)

The equation of the straight line passing through the point and having slope 'm'

y - y₁ = m ( x- x₁)

The equation of the straight line passing through the point ( 0,-7) and slope m = -3

y - (-7) = -3 ( x -0)

y +7 = -3x

3x +y + 7=0

The equation of the line 3x +y + 7=0

Final answer:-

If A,B, and C are the letters selected and we use A twice, B twice, and C once. The number of ways different passwords exist in this scenario are 30.

A password, sometimes known as a passcode (in devices made by Apple, for instance), is a hidden piece of information that is typically a long string of characters and is used to verify a user's identity. Passwords were always thought to be memorized, but today's average person has access to a huge number of password-protected services, making it difficult to remember a different password for each one. The secret is kept by a party known as the claimant, and the person confirming the claimant's identity is known as the verifier, according to the nomenclature of the NIST Digital Identity Guidelines. The verifier can determine the identity of the claimant when the claimant successfully uses a recognized authentication technique to show the verifier that they know the password.

Answer: 79

Step-by-step explanation:

\(\sqrt{k+2}-9=0\\\\\sqrt{k+2}=9\\\\k+2=81\\\\k=\boxed{79}\)

Answer:

D) k = 79

Step-by-step explanation:

Given equation: \(\sf\sqrt{k+2}-x=0\)

Steps:

1. Substitute 9 as the value of x in the equation:

\(\sf\sqrt{k+2}-9=0\)

2. Add 9 to both sides:

\(\sf\sqrt{k+2}-9+9=0+9\\\\\Rightarrow \sqrt{k+2}=9\)

3. Square both sides of the equation:

\(\sf\left(\sqrt{k+2}\right)^2=9^2\\\\\Rightarrow k+2=81\)

4. Subtract 2 from both sides:

\(\sf k+2-2=81-2\\\\\Rightarrow k = 79\)

5. Check your work:

\(\sf\sqrt{k+2}-x=0\ \textsf{[ substitute 79 for k, and 9 for x ]}\\\\\sqrt{79+2}-9=0\ \textsf{[ add ]}\\\\\sqrt{81}-9=0\ \textsf{[ take the square root ]}\\\\9-9=0\ \textsf{[ subtract ]}\\\\0=0\ \checkmark\)

The times interest earned ratio for Camargo, Inc. is 1.87. This means that the company's earnings before interest and taxes (EBIT) are 1.87 times greater than its interest expense.

EBIT = Sales - Cost of Goods Sold - Depreciation Expense = $534,000 - $241,680 - $60,400 = $231,920

Interest Expense = (EBIT - Additions to Retained Earnings) * (1 - Tax Rate) = ($231,920 - $72,800) * (1 - 0.22)

= $129,796.80

Times Interest Earned Ratio = EBIT / Interest Expense = $231,920 / $129,796.80 = 1.87

This indicates that the company has a good ability to cover its interest payments.

The inequality to determine the number of runs per inning, p Kim's team could have scored is; 4r + 6 > 17

Let r represent the number of runs per inning. Thus for 4 innings, we have 4r.

The team already has 6 runs. Now add the additional runs to this to get;

4r + 6

The team wants to score more than the other team, this means they need more than 17 and so the inequality required is;

4r + 6 > 17

Subtract 6 from each side to get;

4r + 6 - 6 > 17 - 6

4r > 11

Divide both sides by 4 to get:

The value of 4/5 x 3/4 in simplest form is 3/5. To find the value of 4/5 x 3/4, we need to multiply the numerators and denominators separately and simplify the resulting fraction to its simplest form. Multiplying the numerators 4 and 3 gives us 12, while multiplying the denominators 5 and 4 gives us 20. So, 4/5 x 3/4 can be written as 12/20.

To simplify 12/20 to its simplest form, we need to find the greatest common factor (GCF) of the numerator and denominator. In this case, both 12 and 20 are divisible by 4, so the GCF is 4. Dividing both the numerator and denominator by 4, we get 3/5. Therefore, the value of 4/5 x 3/4 in simplest form is 3/5.
In conclusion, the value of 4/5 x 3/4 in simplest form is 3/5, which can be obtained by multiplying the numerators and denominators separately and simplifying the resulting fraction by finding its greatest common factor.

To calculate the volume of a rectangular box, you multiply the lengths of its sides.

In this case, the given box has sides measuring 7 inches, 9 inches, and 13 inches. Therefore, the volume can be calculated as:

Volume = Length × Width × Height

Volume = 7 inches × 9 inches × 13 inches

Volume = 819 cubic inches

So, the volume of the given box is 819 cubic inches. The formula for volume takes into account the three dimensions of the box (length, width, and height), and multiplying them together gives us the total amount of space contained within the box.

In this case, the box has a volume of 819 cubic inches, representing the amount of three-dimensional space it occupies.

The hardest part about negative numbers in addition is remembering when to add, rather than subtract. In the last equation, we add the numbers together, because the negative sign cancels out with subtraction. All of the other equations we can follow exactly what it says to do, because there are no minus signs right next to each other.

This is an example of a biased research sample. By only surveying students at a wealthy private college, the researcher may not accurately capture the budgeting behavior of college students as a whole.

The sample is limited and not representative of the entire population of college students. To ensure more accurate and unbiased results, the researcher should consider surveying a diverse range of college students from different socioeconomic backgrounds and institutions. In this scenario, a researcher wants to study budgeting behavior among college students but only surveys students at a wealthy private college with a tuition of $65,000 per year. This is an example of a biased research sample. The sample is not representative of the broader population of college students, as it only includes students from a specific socio-economic background attending a wealthy private college.

The equation of a line perpendicular to line y = 8/3x-5 in slope-intercept form that contains point (-2, -2) is y = -3x/8 - 11/4.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁)

Where:

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

8/3 × m₂ = -1

m₂ = -3/8.

At data point (-2, -2), a linear equation of this line can be calculated in point-slope form as follows:

y - (-2) = -3/8(x - (-2))

y + 2 = -3/8(x + 2)

y = -3x/8 - 3/4 - 2

y = -3x/8 - 11/4

Answer:

\(s=20\)

Step-by-step explanation:

By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two, opposite interior angles.

In other words:

\(4s=(3s-20)+(2s)\)

Solve for s. Combine like terms:

\(4s=5s-20\)

Subtract 5s from both sides:

\(-s=-20\)

And divide both sides by negative one. Therefore:

\(s=20\)
