Solve each system of equations by substitution.

2 x+6 y=14

4 x-8 y=48

Answer:

Answer: a = 15/2 ,

Step-by-step explanation:

Subtract 21 from both sides  16a+21 = 20a-9

16a + 21 -21=- 20a- 9 -21

Simplify the expression

16a + 21 -21=- 20a- 9 -21

16a=20a -30

Subtract 20a from both sides

16a=20a -30

16a - 20a = 20a -30 - 20a

Solution

a = 15/2

The function y = 3x(x + 2)³ has two zeros: x = 0 (with multiplicity 1) and x = -2 (with multiplicity 3). The multiplicity of a zero represents the number of times that zero appears as a root of the function.

To find the zeros of the function, we set y equal to zero and solve for x. In this case, we have: 3x(x + 2)³ = 0

Since the product of factors is zero, we can set each factor equal to zero and solve for x:

1) Setting x = 0, we get 3(0)(0 + 2)³ = 0, which gives us a zero at x = 0 with multiplicity 1.

2) Setting x + 2 = 0, we have 3x(0)³ = 0, which also gives us a zero at x = -2. Since it is raised to the power of 3, it has a multiplicity of 3.

If people are happy, then they rarely correct their faults.

In if-then form, the statement "Happy people rarely correct their faults" can be expressed as an implication. The "if" part of the statement (the condition) is "people are happy," and the "then" part (the consequence) is "they rarely correct their faults."

This form indicates that when the condition is true (people being happy), the consequence tends to occur (they rarely correct their faults).

However, it does not necessarily mean that all happy people will never correct their faults or that correcting faults is solely dependent on happiness. It simply suggests a general tendency or pattern observed where happy individuals are less inclined to address their flaws compared to others.

It seems like you're describing an experiment that will compare different combinations of choices for finishing the raw fabric. The experiment will involve using either metal rollers or natural-bristle rollers to raise the fabric's surface, dyeing the fabric for 30 or 40 minutes, and applying a temperature of either 150°C or 175°C.

In this experiment, the goal is to compare the effects of different combinations of choices for finishing raw fabric. The choices include:

Rollers: The experiment will test two types of rollers: metal rollers and natural-bristle rollers. These rollers are used to raise the surface of the fabric.

Dyeing Cycle Time: Two different dyeing cycle times will be evaluated: 30 minutes and 40 minutes. This refers to the duration for which the fabric is subjected to the dyeing process.

Temperature: Two temperature settings will be tested: 150°C and 175°C. These temperatures represent the heat applied during the fabric finishing process.

For each combination of choices, three fabric specimens will be treated accordingly. Once the treatments are completed, the quality of each fabric specimen will be evaluated and scored. This evaluation will likely involve assessing various attributes such as color vibrancy, texture, smoothness, durability, or any other relevant factors that contribute to fabric quality.

By comparing the scores obtained from each treatment combination, the experiment aims to determine which combination of choices yields the best quality fabric. This information can then be used by Fabric Science, the maker of the fabric, to make informed decisions about their fabric finishing processes.

Simplifying rational expressions is similar to simplifying fractions in that both processes involve reducing the expression to its simplest form. Both rational expressions and fractions involve division, and the goal is to simplify and make the expression or fraction easier to work with or understand.

Similarities:

Common Factors: Both in rational expressions and fractions, you look for common factors in the numerator and denominator. By canceling out these common factors, you simplify the expression.

Division: Both rational expressions and fractions involve division. In fractions, you divide the numerator by the denominator to get the value. In rational expressions, you divide the polynomials in the numerator and denominator.

Differences:

Variables: Rational expressions often involve variables, whereas fractions typically involve numbers. Variables in rational expressions can represent unknown quantities, allowing for more general expressions.

Polynomials: Rational expressions may involve polynomials in the numerator and denominator, whereas fractions usually involve integers or decimals. Simplifying rational expressions requires factoring and canceling out common factors among the polynomials.

Domain Restrictions: Rational expressions can have domain restrictions due to values that make the denominator equal to zero. These restrictions need to be considered when simplifying rational expressions to ensure that the simplified expression is valid within its domain.

In summary, simplifying rational expressions is similar to simplifying fractions in terms of finding common factors and reducing the expression to its simplest form. However, rational expressions involve variables, polynomials, and domain restrictions, which make the simplification process more complex compared to fractions that typically involve numbers.

Given the consumption utility function u(c) = -50c, a daily discount rate of 0.25, and the option to wash your neighbor's car at any time in the next four days, we analyze the optimal timing using different scenarios. In the standard economic model of exponential discounting, the choice of when to wash the car depends on maximizing expected utility. When considering utility from anticipation and consumption with α = 1 or α = 3, as well as when α = 3 but the daily discount rate is changed to 0.99, the optimal timing will be determined by comparing the discounted utility values at each time point.

In the standard economic model of exponential discounting, the optimal timing to wash the car is determined by comparing the discounted utility values for each day. We calculate the present value of utility for each day, discounting it by the daily discount rate of 0.25. The day with the highest present value of utility corresponds to the optimal choice of when to wash the car.

If we introduce utility from anticipation with α = 1, we weigh the utility from future consumption equally with the utility from current consumption. In this case, we still compare the discounted utility values for each day, but we additionally take into account the anticipation utility for future days.

When α = 3, we assign more weight to utility from future consumption compared to utility from current consumption. Thus, the optimal choice will be biased towards later days, as the higher α value emphasizes the anticipation utility.

If we consider α = 3 with a higher daily discount rate of 0.99, the discounting factor becomes stronger. As a result, the present value of utility for future days decreases significantly, making the optimal choice to wash the car shift towards earlier days compared to the previous scenario with a discount rate of 0.25.

If you deposit $14,000 into an account paying 2.1% interest compounded monthly, you will earn approximately $2,450 in interest after 8 years.

To calculate the interest earned, we can use the formula for compound interest: A = [tex]P(1 + r/n)^(nt)[/tex], where A is the final amount, P is the principal amount (initial deposit), r is the annual interest rate (expressed as a decimal), n is the number of times interest is compounded per year, and t is the number of years.

In this case, the principal amount is $14,000, the annual interest rate is 2.1% (or 0.021 as a decimal), and the interest is compounded monthly, so n = 12. The time period is 8 years.

Plugging these values into the formula, we get:

A = [tex]14000(1 + 0.021/12)^(^1^2^*^8^)[/tex]

Calculating this expression, we find that the final amount after 8 years will be approximately $16,449.55. To determine the interest earned, we subtract the initial deposit from the final amount:

Interest earned = $16,449.55 - $14,000 = $2,449.55.

Rounding this to the nearest dollar, the interest earned after 8 years will be approximately $2,450.

To find the standard-form equation of an ellipse, we need the coordinates of the vertices and the focus. The vertices determine the length of the major axis, while the focus determines the distance from the center to the foci.

Given the vertices (3,-1) and (3,-11), we can determine the length of the major axis, which is 2a = |-1 - (-11)| = 10. So, a = 5.

Given the focus (3,-4), we can determine the distance from the center to the foci, which is c = |-4 - (-6)| = 2.

Since the major axis is horizontal, the standard-form equation of the ellipse is (x-h)²/a² + (y-k)²/b² = 1, where (h,k) is the center of the ellipse.

The center of the ellipse is at (3, (-1-11)/2) = (3,-6).

Plugging in the values, we have (x-3)²/5² + (y+6)²/3² = 1, which simplifies to (x-3)²/16 + (y+6)²/36 = 1.

From the question, we have the following parameters that can be used in our computation:

Volume = 8

Base = square

Base = x

So, the volume is

A polynomial is an algebraic expression consisting of variables and coefficients, combined using addition, subtraction, and multiplication operations. It is a mathematical expression that represents a function of one or more variables. The polynomial x⁴ - 4x³ - 5x² can be factored as follows:

x⁴ - 4x³ - 5x² = x²(x² - 4x - 5).

To factor the quadratic expression x² - 4x - 5, we look for two numbers whose product is -5 and whose sum is -4. The numbers -5 and 1 satisfy these conditions, so we can write the quadratic expression as:

x² - 4x - 5 = (x - 5)(x + 1)

Therefore, the polynomial x⁴ - 4x³ - 5x² can be factored as:

x⁴ - 4x³ - 5x² = x²(x - 5)(x + 1)

To check if the factoring is correct, we can multiply the factors together:

x²(x - 5)(x + 1) = x²(x² + x - 5x - 5) = x²(x² - 4x - 5)

Expanding further:

x²(x² - 4x - 5) = x⁴ - 4x³ - 5x²

The factored form matches the original polynomial, so we can conclude that the factoring is correct.

In summary, the polynomial x⁴ - 4x³ - 5x² can be factored as x²(x - 5)(x + 1). This factoring can be verified by multiplying the factors together, which yields the original polynomial.

Answer:

Yes

Step-by-step explanation:
f(x) = 5x^4 - 2x^3 + 3x - 2 + 1 is a polynomial function.Polynomial functions are functions that can be expressed as the sum of power functions in the form f(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + ... + a₁x + a₀, where n is a non-negative integer and a is a constant coefficient.

In this case, the function f(x) is a polynomial function of degree 4 because the highest power of x in the function is 4. The coefficients of the function are also constants, which means that this function satisfies the definition of a polynomial function.

Therefore, we can conclude that f(x) = 5x^4 - 2x^3 + 3x - 2 + 1 is a polynomial function.

The given series, in the same order, is a geometric series. The sum of all 9 terms of the series is -8789085.

To solve this question, we use the basic principles of progressions, both arithmetic and geometric and their properties such as the 'n' th term of the series and the sum-to-n terms.

First, we define what an arithmetic or geometric progression is.

A series, in which the consecutive terms increase or decrease consistently by sum, are called arithmetic progressions.

Let a be the first term of a series.

a, a+d, a+2d, a+3d...

This series is an arithmetic progression, where 'd' is called the 'common difference' between any two consecutive terms.

Similarly, the series in which the consecutive terms grow or fall consistently, but by product, is called geometric progression.

a, ar, ar², ar³....

This is an example of a geometric progression, where 'r' is called the common ratio, between any two consecutive terms.

Now going back to the question, we need to compare any two sets of consecutive terms.

-5 and 25:

Difference: 25 - (-5) = 30

Ratio: 25/-5 = -5

25 and -125

Difference: -125 - 25 = -150

Ratio: -125/25 = -5

As we can see, the ratio is constant, whereas the difference is not.

Thus, we clearly conclude that this is an example of geometric progression.

Now, we need to complete the series by the 9th term. The equation for nth term of a geometric series is:

aₙ = arⁿ⁻¹

We know that a = -5 and r = -5 for the series.

a₉ = ar⁸

   = (-5)(-5)⁸

   = (-5)⁹

   = -1953125

a₈ = ar⁷ = (-5)⁸ = 390,625

a₇ = ar⁶ = (-5)⁷ = -78,125

a₆ = ar⁵ = (-5)⁶ = 15,625

a5 = ar⁴ = (-5)⁵ = -3,125

Series: -5, 25, -125, 625, -3125, 15625, -78125, 390625, -1953125

Finally, we need the sum to 9 terms of the series.

We have the formula,

Sₙ = (n/2)(a + aₙ)

S₉ = (9/2)(-5 -1953125)

S₉ = 4.5(-1953130)

S₉ = -8789085

This is the value evaluated for the given value of n, 9.

The lateral area of the lamp shade is approximately 286.1 square inches to the nearest tenth.

To find the lateral area of the lamp shade, we need to calculate the area of the curved surface of the cylinder.

The formula for the lateral area of a cylinder is given by:

Lateral Area = 2πrh

where r is the radius of the base and h is the height of the cylinder.

Given that the diameter of the shade is 6 \frac{3}{4} inches, we can find the radius (r) by dividing the diameter by 2:

r = \frac{6 \frac{3}{4}}{2}

To convert the mixed number to an improper fraction, we multiply the whole number by the denominator and add the numerator:

r = \frac{27}{4} \cdot \frac{1}{2} = \frac{27}{8}

Now we can substitute the values into the formula:

Lateral Area = 2π \cdot \frac{27}{8} \cdot 18

To approximate the answer to the nearest tenth, we can use the value 3.14 for π.

Lateral Area ≈ 2 \cdot 3.14 \cdot \frac{27}{8} \cdot 18

The polynomial function in standard form with the given zeros x = 5, 6, and 7 is:

f(x) = x^3 - 18x^2 + 107x - 210

To write a polynomial function in standard form with the given zeros x = 5, 6, and 7, we use the fact that if a value x is a zero of a polynomial function, then (x - a) is a factor of the polynomial, where a is the zero.

Using this information, we can construct the polynomial function as follows:

Since the zeros are x = 5, 6, and 7, the factors of the polynomial are (x - 5), (x - 6), and (x - 7).

To obtain the polynomial function, we multiply these factors together:

f(x) = (x - 5)(x - 6)(x - 7)

Expanding this expression, we get:

f(x) = (x^2 - 11x + 30)(x - 7)

Now, let's multiply further:

f(x) = (x^2 - 11x + 30)(x) - 7(x^2 - 11x + 30)

Expanding again:

f(x) = x^3 - 11x^2 + 30x - 7x^2 + 77x - 210

Combining like terms:

f(x) = x^3 - 11x^2 - 7x^2 + 30x + 77x - 210

To complete the square for the expression x² + 11x, we need to find a term that, when added to the expression, creates a perfect square trinomial.

To complete the square, we take half of the coefficient of the x-term, square it, and add it to both sides of the equation. In this case, the coefficient of x is 11, so half of it is 11/2, and when squared, it becomes 121/4. Adding 121/4 to both sides of the equation, we have x² + 11x + 121/4 = x² + 11x + 121/4. Now, the left side of the equation can be factored as a perfect square trinomial, which is (x + 11/2)².

Therefore, the complete square form of x² + 11x is (x + 11/2)².To complete the square for a quadratic expression in the form x² + bx, we take half of the coefficient of the x-term, square it, and add it to both sides of the equation. The result is a perfect square trinomial. In the given expression x² + 11x, the coefficient of x is 11. Half of 11 is 11/2, and when squared, it becomes 121/4.

The value of the operation is x³ - 7x² - 9x + 8.

Here we have been given the functions,

f(x) = x - 8  and  g(x) = x² + x - 1

We need to find (fg)(x))

Since there is no ° sign in between. hence we need to find

(f×g)(x)

This implies we need to multiply the value of the functions f and g at x

= (x - 8)(x² + x - 1)

= x³ + x² - x - 8x² - 8x + 8

= x³ - 7x² - 9x + 8

Hence, the value of the operation is x³ - 7x² - 9x + 8.

The radius of a circle with an area of 271 square inches is,

⇒ r = 9.3 inches

We have to give that,

An area of a circle is,

A = 271 square inches.

Since We know that,

The area of the circle is,

A = πr²

Where r is the radius of the circle.

Substitute A = 271 square inches in the above formula,

271 = 3.14 × r²

r² = 271 / 3.14

r² = 86.3

r = √86.3

r = 9.3 inches

Therefore, The radius of a circle with an area of 271 square inches is,

⇒ r = 9.3 inches
