If rοtate the image with 90 degree abοut οrigin will change the οrientatiοn οf the image but shape will remains same.

A dilatiοn fοllοwed by reflectiοn will change the image because the transfοrmatiοn dilatiοn is used tο resize an item. Dilatiοn is a technique fοr making items appear larger οr smaller.

[Group of answer choices]

Answer:

  graph 4 (reflected vertically)

Step-by-step explanation:

You want the graph that represents a cosine function with no horizontal shift, an amplitude of 2, and a period of 2π/3.

The amplitude of a sine or cosine function is the difference between the positive peak and the centerline. All of the graphs show functions with an amplitude of 2.

The period of the function is the difference of x-values between the first instance of the function and the first repeat: f(x) ≡ f(x+p) has a period of p.

Graphs 1 and 3 show periods of 2π/9; graphs 2 and 4 show periods of 2π/3, as required.

There is an interaction between horizontal shift and vertical reflection. Sine or cosine functions are effectively inverted (reflected over the x-axis) if they are shifted horizontally by 1/2 period—and vice versa.

The function in graph 3 is a sine function, or a horizontally shifted cosine function.

The function in graph 4 is a cosine function that has been shifted 1/2 perior, OR a cosine function that has been reflected over the x-axis.

Graph 4 is the only viable choice for a cosine function with the correct period, so we have to assume it starts at -2 because it has been reflected vertically over the x-axis. (There seems to be no restriction on that in the problem statement.)

Additional comment

Ordinarily, you might not be expected to make any assumptions about vertical reflection. It seems a bit of a trick question.

The calculated length of the arc has a value of 22.34 yards

To find the length of an arc, we can use the formula:

L = (θ/360) x 2πr

where L is the length of the arc, θ is the central angle in degrees, r is the radius of the circle, and π is approximately 3.14.

In this case, the central angle is 160 degrees and the radius is 8 yards. So we can plug in these values to get:

L = (160/360) x 2π(8)

Evaluate

L = 22.34 yards

Therefore, the length of the arc is approximately 22.34 yards

Answer:

5(7j+3) AND 35j +15 are both equal to the expression 5(6j + 3 + j)

The domain of the inverse function f⁻¹⁽ˣ⁾ is (-2, 5), and the range is [3, 4).

The domain refers to the set of input values for which a function is defined. For example, the domain of the function f(x) = √(x) is all non-negative real numbers, because the square root function is only defined for non-negative inputs.

The range refers to the set of output values that a function can produce, given its domain of input values. In other words, it represents the set of possible values that a function can output.

In the given question,

Since f(x) is a one-to-one function, it has an inverse function f⁽⁻¹⁾⁽ˣ⁾, which can be found by switching the roles of x and y and solving for y.

To find the domain and range of the inverse function f⁽⁻¹⁾⁽ˣ⁾, we can use the fact that the domain of f(x) is equal to the range of f^⁽⁻¹⁾⁽ˣ⁾, and the range of f(x) is equal to the domain of f⁽⁻¹⁾⁽ˣ⁾.

So, we have:

Domain of f(x) = [3, 4)

Range of f(x) = (-2, 5)

Range of f⁽⁻¹⁾⁽ˣ⁾ = Domain of f(x) = [3, 4)

Domain of f⁽⁻¹⁾⁽ˣ⁾ = Range of f(x) = (-2, 5)

Therefore, the domain of the inverse function f⁽⁻¹⁾⁽ˣ⁾ is (-2, 5), and the range is [3, 4).

Since the question is asking about total employees, we must add 175 to 500 to get 675. Therefore, the correct answer is 675.

Increase means to grow or make larger in size, amount, degree, or intensity. It is the opposite of decrease, meaning to make or become less.

This is because when there were 500 employees, a 35% increase would be a total of 500 + 35% of 500

= 500 + 175

= 675.

To calculate 35% of 500, we use the formula:

(35/100) × 500 = 175

This means that 35% of 500 is 175, so when we add 175 to 500, we get 675.

Since the question is asking about  total employees, we must add 175 to 500 to get 675.

Therefore, the correct answer is 675.

Vertex: What is it?

A vertex is a location in geometry where two or more curves, lines, or edges converge. It is also referred to as the intersection of an object's edges, faces, or facets to form a corner point of a polygon, polyhedron, or other higher-dimensional polytope. Each of the three corners of a triangle, for instance, is a vertex.

x = -b / 2a

where -10 a and 120 b. By replacing these values, we obtain:

x = -120 / 2(-10) = 6

Let the people stayed be x

Because of this, July is the month with the most guests at the inn (6 months after January).

We may change x = 6 into N(x) to get the number of visitors who stayed at the inn during that month:

We must determine the highest value of N in order to determine the month when the inn had the most guests (x).

N(x) = -10x² + 120x + 120

N(6) = -10(6)² + 120(6) + 120 guests.

N(6) = -360 + 720 + 120

Answer:

460 milliliters

Step-by-step explanation:

We know that the ratio of A to B is 5:7. This means for every 5 milliliters of A, we need 7 milliliters of B. Let's use this ratio to find how many milliliters of A we need for 1104 milliliters of the drug.

First, we need to find out how many sets of 5:7 we have in 1104 milliliters. We can do this by dividing 1104 by the total number of parts in the ratio, which is 5 + 7 = 12.

1104 / 12 = 92

This means we have 92 sets of 5:7 in 1104 milliliters of the drug. To find how many milliliters of A we need, we simply multiply the number of sets by the amount of A in each set, which is 5 milliliters.

92 x 5 = 460

Therefore, we need 460 milliliters of compound A.

cos(x)^2(cos(x)^2+sin(x)^2/cos(x)^2)=1

Cancel cos(x)^2 from the numerator to the denominator.

cos(x)^2(cos(x)^sin(x)^2)/cos(x)^2=cos(x)^2(cos(x)^2+sin(x)^2)/cos(x)^2=cos(x)+sin(x)^2:

Answer:

If Lin's father has an 18% tip for the meal, he will need to pay an additional 0.18 x 23.89 = 4.3 dollars as a tip. This brings the total cost of the meal to 23.89 + 4.3 = 28.19 dollars.

Next, a 7% sales tax is applied to the total cost of the meal, which is 28.19 dollars. The amount of sales tax will be 0.07 x 28.19 = 1.97 dollars.

First, we need to convert the length of the leather cord to inches because the length of the necklace is given in inches.

3 yards = 3 x 3 = 9 feet (since there are 3 feet in a yard)

9 feet = 9 x 12 = 108 inches (since there are 12 inches in a foot)

Now we can divide the length of the leather cord by the length of each necklace:

108 inches ÷ 28 inches = 3.857

Since we cannot make a fraction of a necklace, we round down to the nearest whole number:

3 necklaces

Therefore, Cindy can make 3 necklaces with the piece of leather cord she has.

Answer: 36 m²

Step-by-step explanation:

       First, we will solve for the area of the triangles. Since they are congruent, we will multiply the height times the base. Usually, you would have to divide by two. However, since we have two congruent triangles, we will not be doing this.

       A = BH

       A = (2 m)(6 m)

       A = 12 m²

       Next, we will find the area of the rectangle. We will multiply the length by the width.

       A = BH

       A = (6 m)(4 m)

       A = 24 m²

       Lastly, we will add these two values together.
