For the given rectangle, having perimeter = 72, the length of the rectangle will be 12 cm and breadth will be 24 cm

The overall length of the outline determines a shape's perimeter in two dimensions. We sum the lengths of all four corners of a rectangle to determine its perimeter.

Since the opposing sides of a rectangle are always equal, we must determine the length and breadth of the rectangle in order to determine its perimeter. The rectangle's perimeter may be expressed as the product of its length and breadth times two. As a linear measurement, the perimeter can be expressed in meters, centimeters, inches, feet, etc.

Given,

perimeter = 72

let us assume length = x

The breadth will thus be = 2x.

Now that these numbers have been plugged in, we may solve the equation for x.

perimeter of rectangle = 2 (L + B)

72 = 2 (x + 2x)

72 = 2 (3x)

72 = 6x

x = 72/6

x = 12

The triangle with the given vertices (-1, -1), (2, 3), and (-4, 3) is not an equilateral triangle.

An equilateral triangle can be defined as a special type of triangle that has equal side lengths and all of its three (3) interior angles are equal.

In order to determine whether the triangle with the given vertices is an equilateral triangle, we would apply the distance formula to calculate the length of each side of this triangle as follows:

Mathematically, the distance between two (2) points that are on a coordinate plane can be calculated by using this formula:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

For the vertices (-1, -1) and (2, 3), we have;

A = √[(2 - (-1))² + (3 - (-1))²]

A = √[(2 + 1)² + (3 + 1)²]

A = √[3² + 4²]

A = √[9 + 16]

A = √25

A = 5 units.

For the vertices (2, 3) and (-4, 3), we have;

B = √[(-4 - 2)² + (3 - 3)²]

B = √[-6² + 0²]

B = √[36 + 0]

B = √36

B = 6 units.

For the vertices (-1, -1) and (-4, 3), we have;

C = √[(-4 - (-1))² + (3 - (-1))²]

C = √[(-4 + 1)² + (3 + 1)²]

C = √[-3² + 4²]

C = √[9 + 16]

C = √25

C = 5 units.

Therefore, the triangle with the given vertices is not an equilateral triangle because C = A ≠ B.

SOlution : Domain of (bºa)(x) = [4, ∞]

The term domain is most commonly used to describe the set of values D for which a function (map, transformation, etc.) is defined. For example, a function f(x) that is defined for real values x in R has domain R, and is sometimes said to be "a function over the reals." The set of values to which D is sent by the function is then called the range.

The domain (in its usual established mathematical sense) of a probability density function (and therefore also its distribution function) is available with the undocumented Wolfram Language command DistributionDomain[dist].

The meaning of "domain" in topology is a connected open set.

Another meaning of "domain" is what is more properly known as an integral domain, i.e., a ring that is commutative under multiplication, has an identity element, and no divisors of 0.

In the algebra of the function that is (f ± g)(x), (fg)(x) and (f/g)(x) the domain of the function will be an intersection of the domain of the functions f and g

Here the domain of the product of the function is asked thus the required domain will be an intersection of the domain of the function a and b.

Given a(x) = 3x + 1 ⇒ Domain, D1 = R

b(x) = √(x - 4) ⇒ Domain, D2 = [4, ∞]

Now, Domain of (b*a)(x) = Domain b(x) ⋂ Domain a(x)

= D2 ⋂ D1

= [4, ∞] ⋂ R

= [4, ∞]

Domain of (bºa)(x) = [4, ∞]

The total time she spends playing soccer in a year is 104 hours, which is calculated using the concept of fraction and arithmetic operations.

What is a fraction?

Any numerical number which does not represent the entire quantity is called a fraction. It depicts a part or portion of something. It is generally written in the form of numerator by denominator.

Calculation of the total time Yolanda spends playing soccer

Given that Yolanda plays soccer for 8 ⅔ hours in a month

Firstly, convert the hours in mixed fraction to improper fraction i.e. 8 ⅔ = (8 × 3 + 2) / 3

= 26 / 3

Now, we need to calculate the no. of hours she played in a year, which is done by multiplying the obtained improper fraction with 12

i.e. (26 / 3) × 12

= 104 hours

Hence, Yolanda spends 104 hours a year playing soccer.

The collection of inputs a function can accept is referred to as the domain of the function in mathematics. [tex]dom(f)[/tex]  is a common way to refer to it, with f standing for the function.

To be more specific, the domain of f is X when the function [tex]f:X--Y[/tex] is specified. The domain of a function is not a characteristic of it, but rather an element of the definition in contemporary mathematical terminology.

The function f can be represented as a graph in the Cartesian coordinate system in the particular case where X and Y are both subsets of. A projection of the function's graph onto the graph's x-axis in this instance serves as the domain's representation.

The amount of Linus's money spent on 200 rounds of arcade game is   $55.

The given question is incomplete, so

Lets suppose that Linus has played 200 round of arcade game and now we will need to determine the amount of Linus's money spent on 200 rounds of arcade game.

Entrance fee of an arcade = $5

Additional cost to play one round = $0.25

With the help of given equation ( C=0.25r+5 )  we will determine the amount of Linus's money spent on 200 rounds of arcade game.

'C' = The relationship between the amount of Linus' money spent

'r'  = The number of rounds of arcade games played

Let's solve the equation now,

As we know that r is number of rounds Linus has played which is 200 rounds.

So,     C = 0.25r+5

          C = 0.25 × 200 + 5

          C = 50 + 5

          C =  $55

Hence, we got that Linus has spent total $55 on 200 rounds of arcade game.

Step-by-step explanation:

A fundamental distinction between trend projection and linear regression is that: in trend projection the independent variable is time; in linear regression, the independent variable need not be time.

We need to find the fundamental distinction between trend projection and linear regression.

The trend projection method is based on the assumption that the factors liable for the past trends in the variables to be projected shall continue to play their role in the future in the same manner and to the same extent as they did in the past while determining the magnitude and direction of the variable.

Linear regression: Linear regression analysis is used to predict the value of a variable based on the value of another variable. The variable you want to predict is called the dependent variable. The variable you are using to predict the other variable's value is called the independent variable.

A fundamental distinction between trend projection and linear regression is that in trend projection the independent variable is time; in linear regression, the independent variable need not be time but can be any variable with explanatory power.
