So, the agency made $15,390 on the sale of the house and the agent earned $4,617 in commission.

First, to find out how much the agency made on the house, you need to calculate the commission they received. The commission rate for the agency is 4.5%, so to find the commission you would multiply the sale price of the house ($342,000) by the commission rate (0.045)

$342,000 x 0.045 = $15,390

The agency made $15,390 on the sale of the house.

To find out how much the agent earned in commission, you need to first find out how much the agency earned in commission ($15,390) and then multiply that by the agent's commission rate (30%).

$15,390 x 0.3 = $4,617

The agent earned $4,617 in commission.

The price of one coat is $46.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number. So the percentage actually means a part per 100.

Given that,

a store has 25% off sale on coats.

Discounted price of one coat = $34.50

We have to find the original price of the coat. Let it be x.

x - (25% x) = 34.5

x - 0.25x = 34.5

0.75x = 34.5

x = 46

Hence the original price of the coat is $46.

The end behavior for f(x)=x^5 is asymptotic growth to positive infinity as x approaches positive infinity and asymptotic growth to negative infinity as x approaches negative infinity.

Asymptotic growth is a term used to describe the behavior of a function as it approaches a certain value, usually infinity. In mathematics, an asymptotic function is one that grows or shrinks towards a certain point without ever actually reaching it. In other words, it approaches a limit without bound. Asymptotic growth is often used to describe the rate of growth of a function as its input values approach infinity. It is also used to describe the rate at which a function expands or contracts as its argument approaches a certain point. Asymptotic growth is a useful concept in many areas of mathematics, from calculus to number theory.

This is because x^5 becomes increasingly larger as the absolute value of x increases, resulting in an ever-growing value of f(x).

The ordinate of a typical two-dimensional graph is referred to as the (y) coordinate, while the (x) coordinate is referred to as the abscissa.

The abscissa, also known as the x coordinate of the point, is the distance between a point and the y-axis, scaled with the x-axis. The term "ordinate" refers to a point's separation from the x-axis when scaled with the y-axis. The first coordinate in the plane (x) is referred to as the abscissa and the second coordinate (y) is the ordinate, for instance, if (x, y) is an ordered pair in the Cartesian plane.

Simplifying radicals is the process of reducing a radical expression to its simplest form. There are several ways to simplify radicals, but the most common method is to factor .

The number or expression inside the radical sign and extract any perfect nth root factors.For example: √36 = √(36) = √(6*6) = √(6^2) = 6

Here, 36 can be factorized into 6*6, and since 6 is a perfect square, we can simplify the radical as 6.

Another example: √100 = √(100) = √(10*10) = √(10^2) = 10

Here, 100 can be factorized into 10*10, and since 10 is a perfect square, we can simplify the radical as 10.

Another way to simplify radicals is to use the product property of radicals which states that: √(a*b) = √(a) * √(b)

For example: √(1215) = √(12) * √(15) = √(4355) = √(43) * √(55) = 2√(3) * 5 = 6√(3)

Here, 1215 can be factorized into 4355. And since 43 is a perfect square, we can simplify the radical by taking the square root of 43 and 5*5.

You can simplify radicals as much as possible by applying these methods.

It's important to note that not all radicals can be simplified completely, in some cases we can simplify the radical as much as possible but still have an irrational number inside the radical.

Simplifying radicals is a useful process in algebra and trigonometry, it helps to simplify the expressions and make calculations easier.

                                                           ∑f = 60                        ∑fd = 22

Mean = A + ∑fd/∑f

Mean = 155 + 22/60

Mean = 155 + 0.3

Mean = 155.3

So, the mean height of students in a class is 155.3.

(iii) Given that the mean of data is 27 and the mode is 45

Mode = 3Median - 2Mean

45 = 3Median - 2(27)

45 = 3Median - 54

3Median = 54 + 45

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality.

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.

The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. Finding the x numbers for which the inequality holds true is what we are most interested in.

Polynomial inequality, rational inequality, and absolute value inequality are the various types of inequalities that can exist in mathematics.
