Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and rotation.

Rigid transformations are transformation that produces an image with the same size, shape and angle as the original object. Rigid transformations are translation, rotation and reflection.

Dilation is not a rigid transformation.

All the transformations attached are rigid transformations.

f(2) is -8

According to the question,

Given that,

f(x)=2x-3x^2

Substitute x = 2 into f(x) = 2x-3x^2

f(2)=2x-3x^2

f(2)=2x2 - 3x \(2^{2}\)

f(2)= 4 - 3 x 4

f(2)= 4 - 12

f(2)= - 8

In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math.

Example of an Equation:

4y + 2 = 18

4×2 + 3x − 28 = 0

9m = 49.5

Equation Types

Algebra considers two prominent families of equations, namely polynomial equations and linear equations. Polynomial equations with one variable can be written in P(x) = 0, where P is a polynomial, and ax + b = 0 is the general form of linear equations. Here, a and b are parameters. We can practice geometric or algorithmic methods from linear algebra or mathematical analysis to solve these equations. Also, there are different types of equations, such as:

Linear equations

Quadratic equations

Cubic equations

Quartic equations

Differential equations

Parametric equations

Equation of a line

The standard form of the equation of a line is A x + By + C = 0. The slope-intercept form of an equation is y = mx + b, where m is the slope of the line and b is the y-intercept. However, there are various types of equations to represent lines.

Equation of x-axis

Generally, we say that the equation of the x-axis equation is of the form y = 0. However, we can also write the x-axis equation as x = c where c is constant.

The x-axis comprises all the real values of x, although the value of y is equal to 0 on the complete x-axis.

Thus, x can be recognised as constant and y as 0.

In the coordinate system representation, we can represent any point on the x-axis as (c, 0), where c is any real number.

Therefore, the x-axis formula will be x= c + y

Here,

c = constant

y = 0

The x-axis formula is x = c, where c is constant.

Equation in One Variable

The equation in one variable means the equation containing only one variable. Let’s have a look at the below equations.

17 – 9 = 8

x + 4 = 4y + 22z

4x2 + 3x – 7 = 0

The three examples above represent equations that propose equality (could be true or not) between two expressions.

The first equation does not contain any variable.

The second equation has three different variables, such as x, y and z. Thus, it is a multivariate equation.

The third equation contains only one variable, i.e. x.

A coterminal angle is an angle that has the same initial side and terminal side as a given angle. The difference between the angle and the coterminal angle is a multiple of 360 degrees.

The following steps can be used to find a coterminal angle between 0 and 360 degrees:

Step 1: Identify the given angle. Let's assume that the given angle is 100 degrees.

Step 2: Add or subtract multiples of 360 degrees to the given angle to obtain a new angle that has the same initial and terminal sides. To obtain the angle that is between 0 and 360 degrees, add or subtract 360 degrees from the angle until the result is between 0 and 360 degrees.There are two ways to do this.

The first method is to add or subtract multiples of 360 until the result is between 0 and 360 degrees. The second method is to divide the given angle by 360 degrees and then multiply the quotient by 360 degrees.

The first method:Subtract 360 degrees from 100 degrees to get -260 degrees. Add 360 degrees to -260 degrees to get 100 degrees, which is between 0 and 360 degrees. Therefore, 100 degrees and 460 degrees are coterminal angles between 0 and 360 degrees.

The second method:Divide 100 degrees by 360 degrees to get a quotient of 0.27777777778. Multiply 0.27777777778 by 360 degrees to obtain 100 degrees, which is between 0 and 360 degrees.

Therefore, 100 degrees and 460 degrees are coterminal angles between 0 and 360 degrees.

The area under the curve y = 2x on the interval [0, 3] in the first quadrant is 9 square units.

To find the area under the curve y = 2x on the interval [0, 3] in the first quadrant, we can use the definite integral.

The integral of a function represents the signed area between the curve and the x-axis over a given interval. In this case, we want to find the area in the first quadrant, so we only consider the positive values of the function.

The integral of the function y = 2x with respect to x is given by:

∫[0, 3] 2x dx

To evaluate this integral, we can use the power rule of integration, which states that the integral of x^n with respect to x is (1/(n+1)) * x^(n+1).

Applying the power rule, we integrate 2x as follows:

∫[0, 3] 2x dx = (2/2) * x^2 | [0, 3]

Evaluating this definite integral at the upper limit (3) and lower limit (0), we have:

(2/2) * 3^2 - (2/2) * 0^2 = (2/2) * 9 - (2/2) * 0 = 9 - 0 = 9

Therefore, the area under the curve y = 2x on the interval [0, 3] in the first quadrant is 9 square units.

In the question, the independence assumption may have been violated, while the Nearly Normal Condition is likely justified. Therefore, the use of the Student-t model for inference may be unreliable.

a) In order to perform a hypothesis test on the claim made by the diet guide, we need to assess the assumptions and conditions required for reliable inference. The independence assumption states that the observations are independent of each other. In this case, it is not explicitly mentioned whether the yogurt samples were independent or not. If the samples were obtained from the same batch or were not randomly selected, the independence assumption could be violated.

Regarding the Nearly Normal Condition, which assumes that the population of interest follows a nearly normal distribution, it is reasonable to assume that the distribution of calorie counts in vanilla yogurt is approximately normal. However, since we do not have information about the population distribution, we cannot definitively justify this condition.

b) The appropriate hypotheses for testing the claim made by the diet guide would be:

H0: The average calories per serving of vanilla yogurt is 120.

HA: The average calories per serving of vanilla yogurt is not equal to 120.

To test these hypotheses, we can use a t-test for a single sample. The test statistic (t) can be calculated by taking the mean of the sample calorie counts and subtracting the claimed average (120), divided by the standard deviation of the sample mean. The p-value can then be determined using the t-distribution and the degrees of freedom associated with the sample.

Without the actual sample mean and standard deviation, it is not possible to provide the specific test statistic and p-value for this scenario. These values need to be calculated using the given data (calorie counts) in order to draw a conclusion about the claim made by the diet guide.

Step-by-step explanation:

a) The area of the region D bounded by the given curves is 6.094 units². b) The volume of the solid bounded by the paraboloid z = 4 - x² - y² and the xy-plane is zero

a) To determine the area of the region D bounded by the curves x = y³, x + y = 2, and y = 0, we need to find the intersection points of these curves and calculate the area between them.

First, let's find the intersection points of the curves x = y³ and x + y = 2.

Substituting x = y³ into the equation x + y = 2, we get:

y³ + y - 2 = 0

We can solve this equation to find the values of y. One of the solutions is y = 1.

Next, let's find the y-coordinate of the other intersection point by substituting y = 2 - x into the equation x = y³:

x = (2 - x)³

x = 8 - 12x + 6x² - x³

This equation simplifies to:

x³ - 7x² + 13x - 8 = 0

By factoring or using numerical methods, we find that the other solutions are approximately x = 0.715 and x = 6.285.

Now, let's integrate to find the area between the curves. We integrate with respect to x from the smaller x-value to the larger x-value, which gives us:

Area = ∫[0.715, 6.285] (x + y - 2) dx

We need to express y in terms of x, so using x + y = 2, we can rewrite it as y = 2 - x.

Area = ∫[0.715, 6.285] (x + (2 - x) - 2) dx

= ∫[0.715, 6.285] (2 - x) dx

= [2x - 0.5x²] evaluated from x = 0.715 to x = 6.285

Evaluating this integral, we get:

Area = [2(6.285) - 0.5(6.285)²] - [2(0.715) - 0.5(0.715)²]

= [12.57 - 19.84] - [1.43 - 0.254]

= -7.27 + 1.176

= -6.094

However, area cannot be negative, so the area of the region D bounded by the given curves is 6.094 units².

b) To find the volume of the solid bounded by the paraboloid z = 4 - x² - y² and the xy-plane, we need to integrate the function z = 4 - x² - y² over the xy-plane.

Since the paraboloid is always above the xy-plane, the volume can be calculated as:

Volume = ∫∫R (4 - x² - y²) dA

Here, R represents the region in the xy-plane over which the integration is performed.

To calculate the volume, we integrate over the entire xy-plane, which is given by:

Volume = ∫∫R (4 - x² - y²) dA

= ∫∫R 4 dA - ∫∫R x² dA - ∫∫R y² dA

The first term ∫∫R 4 dA represents the area of the region R, which is infinite, and it equals infinity.

The second term ∫∫R x² dA represents the integral of x² over the region R. Since x² is always non-negative, this integral equals zero.

The third term ∫∫R y² dA represents the integral of y² over the region R. Similar to x², y² is always non-negative, so this integral also equals zero.

Therefore, the volume of the solid bounded by the paraboloid z = 4 - x² - y² and the xy-plane is zero

Given that The volume of air inside a rubber ball with radius r can be found using the function V(r) = \(\frac{4}{3}\pi r^3\), this means that the volume of the air inside the rubber ball is a function of the radius of the rubber ball, that is as the radius of the rubber ball changes, also the volume of the ball changes.

As seen from the function, the radius is directly proportional to the volume of the ball, if the radius increases, the volume also increases.

\(V(\frac{5}{7} )\) is equal to the volume of the ball when the radius of the ball is \(\frac{5}{7}\). Therefore:
