A graph which shows the relationship given in the table is: B. graph with the x axis labeled number of days and the y axis labeled total amount of sunglasses and a line going from the point 0 comma 56 through the point 1 comma 54.

In this scenario, the number of days would be plotted on the x-axis (x-coordinate) of the scatter plot while the total amount of sunglasses would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

From the scatter plot (see attachment) which models the relationship between the number of days and total amount of sunglasses, a linear equation for the line of best fit is given by:

y = -2x + 56

In conclusion, we can reasonably infer and logically deduce that the y-intercept is equal to (0, 56).

A graph of the line that passes through the two points (-3/2, -3/2) and (3/2, 3/2) is shown in the image attached below.

In Mathematics and Geometry, the slope of any straight line can be calculated by using this mathematical equation (expression);

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

From the information provided above, we have the following data points located on the line:

Points on the x-coordinate = (-3/2, 3/2).

Points on the y-coordinate = (-3/2, 3/2).

Substituting the given data points into the slope formula, we have the following;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (3/2 + 3/2)/(3/2 + 3/2)

Slope (m) = 3/3 = 1

At point (-3/2, -3/2), an equation of this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

Where:

y - (-3/2) = 1(x - (-3/2))

y + 1.5 = x + 1.5

y = x

Next, we would use an online graphing calculator to plot the linear equation as shown in the graph attached below.

The selling price for the article if it is equal to marked price will be $117

using profit and loss formulas.

What is profit and loss formula?

Profit and Loss formula is used in mathematics to determine the price of a commodity in the market and understand how profitable a business is. Every product has a cost price and a selling price. Based on the values of these prices, we can calculate the profit gained or the loss incurred for a particular product. The important terms covered under this are cost price, fixed, variable and semi-variable cost, selling price, marked price, list price, margin, etc.

For example, for a shopkeeper, if the value of the selling price is more than the cost price of a commodity, then it is a profit and if the cost price is more than the selling price, it becomes a loss.

Now,

Given Cost price=$65

Marked up price = 180%*$65

As

Marked up price = selling price

Therefore

     selling price= 180%*$65

                 selling price =$117

Terra is correct. In order for a relationship to be a function, each input value must result in only one input.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is often represented as y = f. (x).

You can substitute a homework grade of 37 into the equation in place of x, to find the projected test grade.

Linear regression is a statistical method that is used to study the relationship between two continuous variables, often referred to as the independent variable (x) and the dependent variable (y). The goal of linear regression is to find the best-fitting line that describes the relationship between these two variables. The best-fitting line is known as the regression line, and it is represented by the equation y = mx + b, where m is the slope of the line, and b is the y-intercept.

To find the linear regression equation, we need to use the least squares method to find the line of best fit that describes the relationship between the homework grade (x) and the test grade (y). The equation of the line is in the form of y = mx + b, where m is the slope and b is the y-intercept.

To find the slope (m) and y-intercept (b) we can use the following formulas:

m = (n(Σxy) - (Σx)(Σy)) / (n(Σx²) - (Σx)²)

b = (Σy - m(Σx)) / n

where n is the number of data points, Σx and Σy are the sum of x and y values, Σxy is the sum of the product of x and y values, and Σx² is the sum of the squares of x values.

Given the data points, we can use this information to calculate the slope and y-intercept, and write the linear regression equation.

a. The length of the arc is 6.28cm

b. The area of the sector is 25.12cm²

The arc of a circle is defined as the part or segment of the circumference of a circle. A sector is the space bounded by the arc and the radii of the circle. The smaller area is known as the minor sector and the bigger area is known as the major sector.

The length of an arc = tetha /360 ×2πr

= 2×3.142 = 6.28cm

The area of a sector = tetha / 360 × πr²

= 45/360 × 3.14 × 8× 8

Answer:

The machine makes 45 bottles per minute.

Step-by-step explanation:

We can first find the slope through this equation: [tex]\frac{y2-y1}{x2-x1}[/tex]

Since we are given two points, (2,90) and (7,315), we can plug those two points into the formula given above:

[tex]\frac{315-90}{7-2}[/tex]

= 45

Therefore, m = 45.

Now, we can pick one of the two points given--in this case, I'll use (2,90)--to find the equation of the line: [tex]y-y1 = m(x-x1)[/tex]

For (2,90), y1 will be 90, and x1 will be 2. Let's also plug in m:

y - (90) = 45(x - 2)

We can solve for y now to find what y=mx+b is:

y = 45(x-2) + 90

y = 45x

Since the problem asks how many bottles the machine can make per minute, we can plug x = 1: 45(1) = 45

The machine makes 45 bottles per minute.

The factored expression to the expression is (4y + 1)(y + 6)

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

4 y2 + 25 y + 6

Express properly

So, we have the following representation

4y² + 25 y + 6

Expand the expression

This gives

4y² + 24y + y + 6

Next, we factor the expression

4y(y + 6) + 1(y + 6)

Factor out y + 6

(4y + 1)(y + 6)

Hence, the solution is (4y + 1)(y + 6)

Answer:

x = 60.4

Step-by-step explanation:

First, let's remember the three different trigonometric functions: sine, cosine, and tangent. In this case, we would use cosine because the adjacent side to the angle and hypothenuse are used/given.

[tex]cos(22) = \frac{56}{x}[/tex]

We need to set up a proportion because there is not much else you could do here.

[tex]\frac{cos(22)}{1} =\frac{56}{x}[/tex]

Then, cross-multiply.

[tex]cos(22) * x = 56[/tex]

Finally, divide both sides by cos(22). You'll probably need your calculator and make sure it's in degrees mode and not radians!

[tex]\frac{cos(22) * x}{cos(22)} = \frac{56}{cos(22)}[/tex]

Please find attached the image of the enlargement of the shape X by a scale factor of -1 created using MS Word, which is a drawing equivalent to option B. The correct option is therefore;

B.

An enlargement transformation is one in which the pri-image object size is scaled about a center of enlargement, using a scale factor, with the sign of the scale factor indicating the direction of the enlargement, which for a +ve sign is on the same side, and for a -ve sign is on the other side of the center of enlargement.

An enlargement by a scale factor of -1, can be obtained by producing the image on the alternate side of the center of enlargement, which with a scale factor of -1, is the same size as the size of the image.

Therefore, the dilation by a scale factor of -1, with the center at the origin, produces an image which is equivalent to a reflection of the original object (pre-image), across the y-axis followed by a reflection across the y-axis.

The image of the object following the dilation will therefore be the mirror image of the mirror image of the object reflected across the y-axis, which takes the shape of a vertically flipped, left flipped F, which is option B

Answer:

The equation of a line in the form of y = mx + b, where m is the slope, x is the variable and b is the y-intercept.

Given a point and the slope, we can find the equation of the line that passes through that point. We know that the slope of the line is 0, so we can write the equation of the line as:

y = 0x + b

We also know that the line passes through the point (-3,-8), so we can substitute these values into the equation and solve for b, the y-intercept:

-8 = 0(-3) + b

-8 = 0 + b

b = -8

So the equation of the line that passes through the point (-3,-8) and has a slope of 0 is:

y = 0x - 8

This line is a horizontal line with y-intercept -8, which means that the line passes through the point (0,-8)
