The sequence of transformations that maps the congruent figures are

Rotation, Reflection and Translation.

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

The types of transformations that preserve congruency includes: Rotation Turns a figure around a fixed point.

Since Reflection Flip of figure over a line where a mirror image is created.

And Translation Sliding a shape to a new place without changing the figure.

Answer:

Graph at the bottom right.

Step-by-step explanation:

From the given piecewise function,

1). y = -2  if x ≤ 1

An arrow representing this function will be parallel to x-axis with a dark circle at x = 1.

2). y = 1  if 1 < x ≤ 2

A straight line representing this function will be parallel to x-axis with a dark circle at x = 2 and a hollow circle at x = 1.

3). y = 3  if x > 2

An arrow representing the function will be parallel to the x-axis having one end as a hollow circle at x = 2.

Therefore, Graph at the bottom right will be the answer.

The probability a selected person is both tall and fat is 0.341

From the question, the given parameters are

People = 100

Fat = 55

Tall = 62

So, the individual probabilities are

P(Fat) = 55/100

P(Tall) = 62/100

Evaluate

P(Fat) = 0.55

P(Tall) = 0.62

The probability a person is both tall and fat is

P(Fat and Tall) = P(Fat) * P(Tall)

So, we have

P(Fat and Tall) = 0.55 *  0.62

Evaluate

P(Fat and Tall) = 0.341

Hence, the probability is 0.341

Therefore, the surface represented by the given equation is a sphere centered at the origin with a radius of 6 units.

The given equation rho^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36 represents a surface in spherical coordinates. Let's break down the equation to identify the surface:

ρ^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36

Here, ρ represents the radial distance, φ is the polar angle, and θ is the azimuthal angle.

By analyzing the equation, we can see that it combines both the azimuthal and polar angles. The terms sin^2(φ)sin^2(θ) and cos^2(φ) involve both angles.

The equation ρ^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36 describes a sphere centered at the origin with a radius of 6 units. The constant value of 36 indicates that the squared radial distance from the origin to any point on the surface is 36.

Answer:

D sqrt 1+cos(x)

Step-by-step explanation:

You have to multiply both the top and the bottom by the same thing, because you are essentially multiplying the equation by 1 here, and any number over itself is equivalent to 1 over 1. The reason for this is because you are proving the identity, which means that you can only multiply by 1 or things that equal 1, because you are trying to PROVE that one side equals the other, so you can't rely on the normal processes that you would use to solve a system of equations.

Given:

Graph of function 1.

The equation of function 2 is \(y=\dfrac{1}{2}x+7\).

To find:

The function which has a greater rate of change.

Step-by-step explanation:

From the given graph it is clear that, the function 1 passes through two points (0,0) and (1,2). So, slope of function is

\(m=\dfrac{y_2-y_1}{x_2-x_1}\)

\(m=\dfrac{2-0}{1-0}\)

\(m=\dfrac{2}{1}\)

\(m=2\)

So, rate of change of function 1 is 2.

On comparing the equation \(y=\dfrac{1}{2}x+7\) with \(y=mx+b\), where m is slope and b is y-intercept, we get

\(m=\dfrac{1}{2}\)

So, rate of change of function 2 is \(\dfrac{1}{2}\).

Since, \(2>\dfrac{1}{2}\), therefore, function 1 has a greater rate of change.

Solution :

Function 1 passes through (0,0) and (1,2) .

So, equation of function 1 is :

\(y - 0 = \dfrac{2-0}{1-0}(x-0)\)

y = 2x

Function 2 is : y = 0.5x + 7

We know coefficient of x in linear equation is the slope.

Also, rate of change is directly proportional to slope.

Therefore, function 1 has a greater rate of change.

The steps for subtracting mixed numbers are the transformation of improper fractions, subtraction of denominator, then subtracting numerator, making it the smallest term, and reverse.

Finding the difference between two mixed numbers is required when subtracting mixed numbers. The steps for subtracting mixed numbers are as follows:

Step 1: Transform the mixed values into improper fractions in step 1. To achieve this, divide the total by the denominator, then add the numerator. The new numerator is the outcome, and it is positioned above the denominator.

Step 2: Identify a common denominator in step two. You must identify a common denominator to subtract fractions with various numerators.

Step 3: Subtract the fractions in step three. Subtract the numerators from the fractions while maintaining the same denominator.

Step 4: Make the outcome simpler. Simplify the outcome if you can by breaking the fraction down into its smallest terms. 13/4 in this instance may be expressed as 3 1/4.

Step 5: Reverse the incorrect fraction to a mixed number in step 5. Divide the numerator by the denominator to return the improper fraction to a mixed number. The full number serves as the numerator, and the remainder serves as the quotient.

The question is -

How to Subtract mixed numbers?

The total number of tasks Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed

The factor 'x' in the expression '90x - 20' represents the total number of tasks that Terrence completed in the game.

To understand why, let's break down the given information. It states that Shelly and Terrence completed a different number of tasks. Shelly earned 90 points on each task, so the total number of tasks she completed is not represented by 'x'.

On the other hand, Terrence's total points were 20 less than Shelly's total. This means that Terrence's total points can be calculated by subtracting 20 from Shelly's total points. Since Shelly earned 90 points on each task, her total points would be 90 multiplied by the number of tasks she completed.

So, the expression '90x - 20' represents Terrence's total points in the game, where 'x' represents the total number of tasks that Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed, we can calculate his total points.

Therefore, the correct answer is: The total number of tasks Terrence completed.

I. Simultaneous equations system refers to a set of equations where multiple unknown variables are solved simultaneously. These equations are interdependent and must be solved together.

II. Exogenous variables are independent variables in a statistical or economic model. They are not influenced by other variables in the model and are often determined outside the system being analyzed.

III. Endogenous variables, on the other hand, are dependent variables in a statistical or economic model. They are influenced by other variables in the model and are determined within the system being analyzed.

IV. Structural form model is a representation of a system that shows the relationships between endogenous and exogenous variables. It describes the underlying theory or causal relationships between variables.

V. Reduced form model is a simplified version of the structural form model, where all variables are expressed as functions of exogenous variables. It focuses on the relationships between endogenous variables without considering the underlying theory or causality.

The necessary components to describe a rotation on a coordinate plane include the center of rotation, the shape of the figure, and the number of degrees of rotation.

To describe a rotation of a figure on a coordinate plane, the necessary components include the center of rotation, the shape of the figure, and the number of degrees of rotation.

a. The center of rotation is a fixed point around which the figure rotates. It serves as the anchor for the rotation and determines the position of the figure after the rotation is applied.

b. The shape of the figure refers to its size, proportions, and geometric characteristics. This information is crucial as the figure retains its original shape during the rotation.

c. The number of degrees of rotation determines the magnitude of the rotation. It specifies how much the figure is rotated around the center of rotation. Positive angles indicate counterclockwise rotations, while negative angles represent clockwise rotations.

d. The direction of rotation is not necessary to describe a rotation on a coordinate plane. The rotation can be defined solely by the center, shape, and angle of rotation.

In summary, the essential components to describe a rotation on a coordinate plane include the center of rotation, the shape of the figure, and the number of degrees of rotation. The direction of rotation is not required to define the rotation.
