The perimeter of the square is 40 meters.

The complete length that a square's edge in a plane covers is known as its perimeter. The route that encircles a form is called the perimeter.

By summing all the sides of a closed geometrical object (two-dimensional), the perimeter is determined. Since a square is a polygon with four equal sides, its perimeter will be equal to the sum of those sides.

Since all the sides of a square are equal, therefore, the perimeter of the square will be 4 times its side, i.e. 4 × Side. It is measured in units, such as m, cm, in, ft, etc.

Because a square has four sides of equal length, the perimeter is 12 m+12 m+12 m+12 m=48.0m

Thus, The perimeter of the square is 40 meters.

The volume of the cake is 198 cubic inches.

We are given that the volume of the cake is a function of its width:

V(w) = 1/2w^3 + 5/2w^2

To find the volume when the width is 6 inches, we simply substitute 6 for w in the equation:

V(6) = 1/2(6^3) + 5/2(6^2)

Expanding the exponents and simplifying:

V(6) = 1/2(216) + 5/2(36)

V(6) = 108 + 90

V(6) = 198 cubic inches

So the volume of the cake when the width is 6 inches is 198 cubic inches.

The only function in the relations given is graph C which can be determined using vertical line test.

In mathematics, a function is a relation between a set of inputs, called the domain, and a set of possible outputs, called the range.

A function assigns exactly one output to each input, and each input can only have one output. This means that a function will always give the same output for the same input.

Functions can be classified in different ways. For example, some functions are linear, meaning that the graph of the function is a straight line. Other functions are non-linear, meaning that the graph of the function is not a straight line.

The vertical line test is a method used to determine if a graph represents a function. A graph is a visual representation of a set of points, where each point is defined by a pair of coordinates (x, y).

A graph represents a function if and only if no vertical line intersects the graph more than once. In other words, for any value of x, there should be exactly one corresponding value of y. If a vertical line intersects the graph more than once, it means that there are multiple values of y for the same value of x, which violates the definition of a function.

The vertical line test can be used to determine if a graph is a function by drawing a vertical line on the graph and seeing if it intersects the graph at more than one point. If it does, then the graph is not a function. If it doesn't, then the graph is a function.

Using vertical line test for each of the relation given, only graph C is a function which is a quadratic function.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The given function is f(x) = -4(x-12)^2+5

f(x) = -4(x-12)²+5

Apply the formula for (a - b)²=(a² - 2ab + b²)

f(x) = -4(x-12)²+5

-4[x² - 24x + 144] + 5

To find the value of f(6), substitute the value of x as 6.

= -4[(6)² - 24(6) + 144] + 5

Simplify the expression inside the brackets -

= -4 [36 - 144 + 144] + 5

= -4 (36) + 5

Simplify the expression further to get the value -

The  value of r is 4 , so the line that passes through the pair of points has the given slope. (r, 2), (6, 3), m=1/2.

The ratio of the change in the y coordinate to the change in the x coordinate is known as the slope of a line. The terms Y and x, respectively, stand for the net change in the y-coordinate and the net change in the x-coordinate. where "m" denotes a line's slope. The outcome is that a line's slope is tan.

Two points along the selected line should have their coordinates determined. The difference between these two places' y-coordinates should be determined (rise).

The difference between these two places' x-coordinates should be determined (run). Divide the y-coordinate difference by the x-coordinate difference (rise/run or slope).

Given Points are (r, 2), (6, 3) , slope m = 1/2

(3 - 2)/(6 - r) = (1/2)

Simplifying the above equation, then we get

6 - r = 2

r = 4

Therefore, (r, 2), (6, 3), m = 1/2 the slope of the line passing through each pair of points is r = 4.

Bayes's Theory is an important tool for understanding probability and for determining the likelihood of certain outcomes occurring.

It states that the probability of an event occurring if another event has already occurred is generally different from the probability of the second event occurring if the first one has already occurred. This is a common mistake made by medical professionals, particularly when interpreting test results.

For example, in a study conducted in both Germany and the United States, researchers asked physicians to estimate the probability that an asymptomatic woman between the ages of 40 and 50 who has a positive mammogram actually has breast cancer. The physicians were told that 7 percent of mammograms show cancer when there is none, the actual incidence of cancer is 0.8 percent, and the false-negative rate is about 10 percent. Through the use of Bayes's Theory, it can be determined that a positive mammogram is due to cancer in only about 9 percent of the cases.

However, in the German group, one-third of the physicians concluded that the probability was about 90 percent, and the median estimate was 70 percent. In the American group, 95 out of 100 physicians estimated the probability to be around 75 percent. This example shows how medical professionals can make mistakes when interpreting test results, due to a lack of understanding of Bayes's Theory.

In order to avoid making such mistakes, medical professionals need to be educated on Bayes's Theory and its importance in determining the probability of certain outcomes occurring. By doing so, medical professionals can increase their accuracy in interpreting test results and make better decisions for their patients.

What is a linear inequality ?

In mathematics, inequality denotes a mathematical expression in which neither side is equal. In Math, an inequality occurs when a connection produces a non-equal comparison between two expressions or two integers. The equal sign "=" in the phrase is substituted by any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), or not equal to symbol (≠). In mathematics, there are three types of inequalities: polynomial inequalities, rational inequalities, and absolute value inequalities.

The symbols "< and '>' represent strict inequalities, whereas  ‘≤’ and ‘≥’ represent slack inequalities. A linear inequality appears to be a linear equation, however there is a difference in the formula.

The x-intercept is the shortest distance of the point on the x-axis from the origin, where the line cuts the x-axis, and the y-intercept is the shortest distance of the point on the y-axis from the origin, where the line cuts the y-axis. Also considering the points, the line cuts the x-axis at the point(a, 0), and it cuts the y-axis at the point(0, b).

Intercept Form of Equation of a Line: x/a + y/b = 1.
