Just add the coordinates of another point to translate it.

Really simple, you have a vector like <f(x), g(x)>  (the vector is defined by functions just because it does not need to be a constant one) that starts at the origin, if you want to translate it to a point (a, b) (so our vector starts there now) just add any point like (a, b) so you get:

<f(x), g(x)> + (a, b) = <f(x) + a, g(x) + b>

Now your vector starts at the point (a, b), so you translated it. So that is the rule to translate vectors by using integer operations.

Answer:

A. 2

Step-by-step explanation:

Let's interpret the function.

First, let's look at the top section:

[tex]f(x)=x+2[/tex] if [tex]x < 1[/tex]

So, if the value of x is less than 1, to find f(x), we should add 2 to x.

Let's check if x is less than 1:

[tex]x=3\\x < 1\\3 < 1[/tex]

3 is not less than one, so to find f(x), we cannot add 2 to x.

The second part of the function is:

[tex]f(x)=x-1[/tex] if [tex]x\geq 1[/tex]

So, if the value of x is greater than or equal to 1, to find f(x), we should subtract 1 from x.

Let's check if x is greater than or equal to 1:

[tex]x=3\\x\geq 1=\\3\geq 1[/tex]

3 is greater than or equal to 1, so to find f(x), we should use x-1.

[tex]x-1=\\3-1=\\2[/tex]

Thus, f(3) = 2; the answer is A.

The area of Pac-Man to the nearest tenth mm² is 11.4 mm².

A circle's area is the area that it takes up in a two-dimensional plane. It can be simply calculated using the formula A = r2, (Pi r-squared), where r is the circle's radius.

To find the area of Pac-Man, we need to calculate the area of the sector that corresponds to the angle of his open mouth and subtract the area of the isosceles triangle formed by the two radii of the sector and the chord that represents the straight edge of his mouth.

First, we need to calculate the angle in radians that corresponds to the 60° angle given:

angle in radians = (60/360) x 2π = π/3 radians

Next, we can use the formula for the area of a sector:

Area of sector = (angle in radians / 2π) x πr²

where r is the radius of the circle.

Area of sector = (π/3 / 2π) x π(13mm)² ≈ 84.95 mm²

Now, we need to calculate the area of the triangle. We can use the formula for the area of an isosceles triangle:

Area of triangle = (1/2) x base x height

where the base is the chord that represents the straight edge of Pac-Man's mouth, and the height is half the length of the chord times the sine of half the angle of the mouth opening.

The base of the triangle is given by the formula:

base = 2r x sin(angle/2)

base = 2(13mm) x sin(30°) ≈ 22.52 mm

The height of the triangle is given by the formula:

height = (base / 2) x sin(angle/2)

height = (22.52 mm / 2) x sin(30°) ≈ 6.53 mm

Therefore, the area of the triangle is:

Area of triangle = (1/2) x base x height ≈ 73.5 mm²

Finally, we can subtract the area of the triangle from the area of the sector to get the area of Pac-Man:

Area of Pac-Man ≈ 84.95 mm² - 73.5 mm² ≈ 11.4 mm²

Therefore, the area of Pac-Man to the nearest tenth mm² is 11.4 mm².

In a regression equation, the estimated coefficients represent the change in the dependent variable for a one-unit increase in the corresponding independent variable, holding all other independent variables constant.

For example, if the estimated coefficient for television advertising is 0.5, then we can interpret it as a $0.5 increase in the dependent variable (such as sales) for every one-unit increase in television advertising expenditure, holding newspaper advertising constant.

Whether the interpretations of the estimated coefficients are reasonable depends on the data and the research question being investigated.

A completely randomized model in a single factor study means that the assignment of treatments is completely random, with no underlying pattern or bias.

When analyzing the difference in means between treatments in a single factor, a completely randomized model means that each individual or unit in the study has an equal chance of being assigned to any of the treatment groups.

In other words, the assignment of treatments is completely random, with no underlying pattern or bias.

This type of experimental design is important because it helps to minimize the effects of confounding variables and other sources of bias.

By randomly assigning treatments to study participants, researchers can be confident that any observed differences in the outcome variable are due to the treatment itself, rather than to other factors that may vary between the groups.

In statistical analysis, a completely randomized model can be used to test whether there are significant differences in the means between the different treatment groups.

This can be done using methods such as analysis of variance (ANOVA) or t-tests, depending on the number of treatment groups and the type of outcome variable being measured.

Overall, the completely randomized model is an important tool for ensuring that the assignment of treatments in a single factor study is unbiased and that the resulting data are suitable for statistical analysis.

It is not possible for a subset of A to contain elements of Ac

To answer the question, "Can a subset of A contain elements of Ac?" we must first understand what these terms mean.

A subset of A is a set that contains only elements that are also in A. On the other hand, Ac is the complement of A, which is the set of all elements that are not in A. Therefore, an element that is in Ac is not in A.

Now, let us consider the possibility of a subset of A containing elements of Ac. If an element is in Ac, it is not in A. Therefore, it cannot be in any subset of A, as all elements of a subset must be in A. This means that it is not possible for a subset of A to contain elements of Ac.

In summary, It is not possible for a subset of A to contain elements of Ac because the complement of A includes all the elements that are not in A. Therefore, any element that is in Ac cannot be in any subset of A

The new vertices of the rotated triangle ABC are (-y₁, x₁), (-y₂, x₂), and (-y₃, x₃).

To rotate a triangle 270 degrees clockwise with the origin as the centre of rotation, you can follow these steps:

Draw the coordinates of the vertices of the triangle. Let's assume that the coordinates of vertex A are (x₁, y₁), the coordinates of vertex B are (x₂, y₂), and the coordinates of vertex C are (x₃, y₃).

To rotate the triangle 270 degrees clockwise, you need to reflect it first over the x-axis, and then over the y-axis.

To reflect the triangle over the x-axis, you need to change the sign of the y-coordinates of each vertex. So the new coordinates of vertex A would be (x₁, -y₁), the new coordinates of vertex B would be (x₂, -y₂), and the new coordinates of vertex C would be (x₃, -y₃).

To reflect the triangle over the y-axis, you need to change the sign of the x-coordinates of each vertex. So the final coordinates of vertex A would be (-y₁, x₁), the final coordinates of vertex B would be (-y₂, x₂), and the final coordinates of vertex C would be (-y₃, x₃).

These final coordinates represent the vertices of the rotated triangle.

An angle is a polyhedron made up of two rays with a shared terminal, often known as sides or legs (called the vertex). Angles are used to express how much rotation or inclination there is between second line or planes and are commonly described in degrees or radians.

From the given information, we have the following equations:

[tex]x = 2(y+z) - 40[/tex] (the largest angle is 40 degrees less than twice the sum of the other two angles)

[tex]x = 2z + 10[/tex] (the largest angle is twice the smallest angle plus 10 degrees)

[tex]x + y + z = 180[/tex] (the sum of the angles of a triangle is 180 degrees)

To simplify the system of equations, we can use the second equation to substitute for x in the first equation:

[tex]2z + 10 = 2(y+z) - 40[/tex]

Simplifying this equation, we get:

[tex]y = z + 25[/tex]

Now we can substitute x and y in terms of z into the third equation:

[tex]x + (z+25) + z = 180[/tex]

Simplifying this equation, we get:

[tex]x + 2z = 155[/tex]

Finally, we can substitute x in terms of z from the first equation into this last equation:

[tex]2(y+z) - 40 + 2z = 155[/tex]

Simplifying this equation, we get:

[tex]y + 3z = 97[/tex]

Therefore, the equations that represent this system are:

[tex]x = 2(y+z) - 40\\y = z + 25\\x + 2z = 155\\y + 3z = 97[/tex]
