Answer:

Explanation:

To simplify a polynomial, we have to do two things: 1) combine like terms, and 2) rearrange the terms so that they're written in descending order of exponent.

First, we combine like terms, which requires us to identify the terms that can be added or subtracted from each other. Like terms always have the same variable (with the same exponent) attached to them. For example, you can add 1 "x-squared" to 2 "x-squareds" and get 3 "x-squareds", but 1 "x-squared" plus an "x" can't be combined because they're not like terms.

Let's identify some like terms below.

f(x)=−4x+3x2−7+9x−12x2−5x4

Here you can see that -4x and 9x are like terms. When we combine (add) -4x and 9x, we get 5x. So let's write 5x instead:

f(x)=5x+3x2−7−12x2−5x4

Let's do the same thing with the x-squared terms:

f(x)=5x+3x2−7−12x2−5x4

f(x)=5x−9x2−7−5x4

Now there are no like terms left. Our last step is to organize the terms so that x is written in descending power:

f(x)=−5x4−9x2+5x−7

Step-by-step explanation:

the company is making a general assumption that, on average, consumers choosing the red dress have a less price-elastic demand, indicating a higher willingness to pay for the specific color option.

The assumption that the company makes about consumers who buy the red dress compared to those who buy the black dress is option a: Consumers that buy the red dress have a less price-elastic (or more price-inelastic) demand than those that buy the black dress.

Price elasticity of demand measures the responsiveness of quantity demanded to a change in price. When the company prices the red dress 30% higher than the black dress, they are assuming that consumers who choose the red dress are less sensitive to changes in price compared to those who choose the black dress. In other words, the company believes that consumers who prefer the red dress are willing to pay a higher price for the desired color and are less likely to be deterred by the price increase.

This assumption is based on the idea that certain consumer segments may have different preferences and willingness to pay for specific attributes or characteristics of a product, such as color. By setting a higher price for the red dress, the company is targeting consumers who value the red color more and are willing to pay a premium for it.

It is important to note that this assumption may not hold true for all consumers, as individual preferences and price sensitivity can vary. Some consumers who prefer the red dress may still be price-sensitive and may switch to the black dress if the price difference is too significant.

Therefore, the solution to the system of linear equations is: x₁ = -5, x₂ = 11, x₃ = -18.

To solve the system of linear equations:

3x₁ + 2x₂x₃ = 10

-x₁ + 3x₂ + 2x₃ = 5

x₁ - x₂ - x₃ = -1

We can use various methods such as substitution, elimination, or matrix methods. Here, we'll use the elimination method.

Step 1: Multiply the second equation by 3 and add it to the first equation:

3x₁ + 2x₂x₃ = 10

-(3x₁ - 9x₂ - 6x₃ = 15)

-7x₂ - 4x₃ = -5 (Equation A)

Step 2: Multiply the third equation by 3 and add it to the first equation:

3x₁ + 2x₂x₃ = 10

(3x₁ - 3x₂ - 3x₃ = -3)

-x₂ - x₃ = 7 (Equation B)

Step 3: Add Equation A and Equation B:

-7x₂ - 4x₃ = -5

+(-x₂ - x₃ = 7)

-8x₂ - 5x₃ = 2 (Equation C)

Step 4: Multiply Equation B by 8 and subtract it from Equation C:

A given shape that is bounded by three sides and has got three internal angles is referred to as a triangle. Types of triangles include right angle triangle, isosceles triangle, equilateral triangle, acute angle triangle, etc. The sum of the internal angles of any triangle is \(180^{o}\).

In the given question, point P is such that <APB = <APC = <BPC = \(120^{o}\). Also, line PB bisects <ABC into two equal measures. Thus;

<ABP = \(30^{o}\)

Thus,

<ABP + <APB + <BAP = \(180^{o}\)

30 + 120 + <BAP = \(180^{o}\)

<BAP = \(180^{o}\) - 150

<BAP = \(30^{o}\)

Apply the Sine rule to determine the value of PB, such that;

\(\frac{AP}{Sin B}\) = \(\frac{BP}{Sin30}\)

\(\frac{8}{Sin30}\) = \(\frac{BP}{Sin 30}\)

Answer:

a.

Step-by-step explanation:

this is a y = mx + b equation

the “B” is the y-intercept. So look where the line crosses the 6 axis. The equation says -1. Right away, there are only two answers that could possibly be it. A and B. The Lines both cross at -1 on the y-axis.

the ”mx“ part of the equation is the slope. Slope is the change in y over the Change in x.

in other words:

y1-y2

———

x1-x2

another thing is that slope in this equation is negative. This means the line is decreasing or going/pointing down. The only possible answer is a.

Answer:

\(y = 120x \)

Step-by-step explanation:

Equation of a straight line is

\(y = mx + b\)

m= slope of line = rise/run which can be computed by taking two points on the line, finding the difference I the y coordinate values and dividing by the correspoding difference in their x coordinate values

b is the y-intercept where the line crosses the y-sxis

Looking at the graph we can see that the line crosses the y-sxis at the origin (0, 0) so the y-intercept is at y=0

The slope is determined by examining the two highlighted points (3, 360) and (2, 240)

Slope =

\( \frac{360 - 240}{3 - 2} = \frac{120 }{1} = 120\)

So equation of line is

\(y = 120x + 0\)

or

\(y = 120x\)

Y= 5, then x = 20/3. We could also choose a different value of y and get a different value of x, but the sum of the areas of the rectangles will always be 30 square centimeters.

Rectangles are commonly found in architecture, engineering, and mathematics. They are used to model many real-world objects, such as doors, windows, computer screens, and paper. The shape and properties of a rectangle make it useful for many practical applications, such as calculating the area of a room or the size of a photo.

The diagonals of a rectangle are equal in length and bisect each other, forming two congruent right triangles. The length of the diagonals can be found using the Pythagorean theorem. The rectangle is also a special case of a rhombus, which has all four sides equal in length, and a square, which has all four sides equal in length and four right angles.

We know that the sum of the areas of the two rectangles is 30 square centimeters. We can use the formulas for the area of a rectangle to set up an equation:

Area of Rectangle 1 + Area of Rectangle 2 = 30

length * width + length * width = 30

Substituting the given values for the lengths of the rectangles:

3x + 2y = 30

This is a linear equation in two variables, x and y. We can solve for one variable in terms of the other:

3x = 30 - 2y

x = (30 - 2y)/3

This gives us the value of x in terms of y. We can substitute this expression for x into the equation above and solve for y:

3x + 2y = 30

3[(30 - 2y)/3] + 2y = 30

30 - 2y + 2y = 30

0 = 0

This equation is always true, which means that there are an infinite number of solutions. We can choose any value of y, and then use the expression for x in terms of y to find the corresponding value of x.

For example, let's choose y = 5. Then:

x = (30 - 2y)/3 = (30 - 10)/3 = 20/3

So, if y = 5, then x = 20/3. We could also choose a different value of y and get a different value of x, but the sum of the areas of the rectangles will always be 30 square centimeters.

The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.

To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.

Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.

To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.

Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.

Therefore, the slope of the line that divides the region into two equal areas is 5.

The expected correlation between the supply of a commodity (x) and the price of a commodity (y) depends on the nature of the commodity and market dynamics. However, in general, we would expect a **negative correlation** between the supply of a commodity and its price. Correct option is C.

The law of supply states that as the supply of a commodity increases, assuming demand remains constant, the price tends to decrease. This is because an increase in supply leads to a higher quantity of the commodity available in the market, potentially causing an excess supply or surplus. In such situations, suppliers may lower prices to attract buyers and reduce their inventory.

Conversely, when the supply of a commodity decreases, assuming demand remains constant, the price tends to increase. A decrease in supply results in a lower quantity available in the market, potentially leading to a scarcity or shortage. In such scenarios, suppliers may increase prices to maximize their profits due to the limited availability of the commodity.

It's important to note that real-world markets can be influenced by various factors, including changes in demand, production costs, technological advancements, government policies, and market competition, which can complicate the relationship between supply and price. Nonetheless, the general expectation is that a decrease in supply tends to lead to an increase in price, and an increase in supply tends to lead to a decrease in price, indicating a negative correlation.

The surface given by the equation \(4x^2 - 16y^2 + z^2 = 16\) is a hyperboloid of two sheets. It consists of two distinct surfaces that intersect along the z-axis and open upwards and downwards.

To identify the surface defined by the equation \(4x^2 - 16y^2 + z^2 = 16,\) we can analyze the equation and determine its geometric properties.

First, let's rewrite the equation in a standard form:

\(4x^2 - 16y^2 + z^2 = 16\)

By rearranging terms, we have:

\((x^2/4) - (y^2/1) + (z^2/16) = 1\)

Comparing this equation to the standard form of a hyperboloid, we can see that the x and z terms have positive coefficients, while the y term has a negative coefficient. This indicates that the surface is a hyperboloid of two sheets.

The trace of the surface can be obtained by setting one variable constant and examining the resulting equation. Let's consider the traces in the xz-plane (setting y = 0) and the xy-plane (setting z = 0).

When y = 0, the equation becomes:

\(4x^2 + z^2 = 16\)

This represents an ellipse in the xz-plane centered at the origin, with the major axis along the x-axis and the minor axis along the z-axis.

The impact of removing an influential point on the new regression line depends on the nature of the influential point and its relationship to the rest of the data points.

How will the removal of the influential point affect the new least-squares regression line for the remaining points?

The removal of an influential point from a dataset can have a significant effect on the regression line. An influential point is a point that has a large impact on the regression line, meaning that if it were removed, the slope and intercept of the regression line would be significantly different.

If the influential point is an outlier, its removal can result in a new regression line that is closer to the remaining data points. This is because the presence of the outlier may have pulled the original regression line away from the majority of the data points.

However, if the influential point is not an outlier but instead represents a critical data point, such as a point representing an important case or condition, its removal can result in a regression line that does not accurately represent the relationship between the remaining data points.

Explanation: A process chart is a graphical tool used to monitor processes in production and service industries. The average process performance and the upper and lower limits are calculated and displayed on an X-bar chart, which is a common process chart. The values for a variable can be collected and analyzed using process charts. An \( \bar{X} \) chart, commonly known as an x-bar chart, is used to monitor a process with continuous numerical data. A binary outcome variable, on the other hand, has only two possible outcomes (e.g., yes/no, pass/fail, etc.). As a result, binary data is unsuitable for an \( \bar{X} \) chart, which is only used to monitor continuous numerical data.

Variables are values that may be altered in a process, which can affect its results. Variables may be categorized as continuous or discrete, depending on whether they can be measured or counted. Discrete variables, such as the number of employees working on a task or the number of items produced in a process, are quantifiable and can be measured precisely. Continuous variables, such as the temperature, length, or weight, can take on any value over a range and are therefore less specific. The reasons for holding inventory include serving as a buffer against uncertainties, ensuring product availability and preventing stockouts, reducing lead times and transportation costs, taking advantage of discounts and bulk purchasing opportunities, and providing a hedge against inflation and price fluctuations.

Answer:

a=148.50

b=0.045

c=8

Step-by-step explanation:

i just took the quiz on edgeunity

All the value of variables are,

a = 148.50, b = 0.05, and c = 8

Now, For the values of a, b, and c in the table, we can use the formula for simple interest:

I = Prt

where I is the interest earned in dollars,

P is the principal in dollars,

r is the interest rate per year as a decimal, and t is the time in years.

Hence, By Using this formula, we can solve for the missing values in the table as follows:

For the first row, we have

P = 3300, r = 0.045, and t = 1.

We can plug in these values and the given value of a = into the formula to solve for a:

a = Prt

a = 3300 x 0.045 x 1

a = 148.50

Therefore, a = 148.50 for the first row.

For the second row, we have P = 3300, t = 3, and I = 445.50.

We can plug in these values and solve for r:

I = Prt

445.50 = 3300 x r x 3

r = 0.05

Therefore, b = 0.05 for the second row.

For the third row, we have P = 3300, t = 7, and I = 1039.50. We can plug in these values and solve for r:

I = Prt

1039.50 = 3300 x r x 7

r = 0.045

Therefore, c = 7 for the third row.

For the fourth row, we have P = 3300, t = c, and I = 1188.00. We can plug in these values and solve for c:

I = Prt

1188.00 = 3300 x 0.045 x c

c = 8

Therefore, c = 8 for the fourth row.

Thus, we have a = 148.50, b = 0.05, and c = 8 to complete the table.
