b) The linear function that best represents the blue line is given as follows: y = x - 2.

c) Two coordinates of the red line are given as follows: (0,4) and (1,0).

d) The coordinates of the blue line are given as follows: (0,-2) and (2,0).

What are the linear functions?

The slope-intercept definition used to define a linear function from it's graph is given as follows:

y = mx + b.

In which the coefficients are listed as follows:

m is the slope, representing by how much y changes when x is increased by one.b is the y-intercept, representing the value of y when the graph of the function crosses the y-axis.

For the red line, two points are given as follows:

(0,4) and (1,0)

Hence the parameters are of:

b = 4, a when x = 0, y = 4.m = -4, as when x increases by one, y decays by 4.

Thus the equation is of:

y = -4x + 4.

For the blue line, the equation is of:

y = x - 2.

As:

When x = 0, y = -2.When x increases by 2, y also increases by 2, hence the slope is of m = 2/2 = 1.

How can I determine a graph's domain?

Graphs can be used as another tool for determining the domain and range of functions. The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The y-axis on a graph represents the possible output values, or range.Consider the function y = f(x), which has the independent variable x and the dependent variable y. A value for x is said to be in the domain of a function f if it successfully allows the production of a single value y using another value for x.

What is the exterior angle property of a triangle?

The exterior angle property of a triangle states that the sum of the measures of the two non-adjacent angles of a triangle is equal to the measure of the exterior angle of the triangle. This means that if a triangle has three interior angles, the measure of any non-adjacent angle of the triangle must be equal to the measure of the exterior angle of the triangle. This property is useful in solving for unknown angles when the measures of two angles are known. For example, if two angles of a triangle measure 30° and 45°, then the measure of the third angle must be 105°, which is the same measure of the exterior angle.

The Exterior angle is = Sum of the Interior opposite angles.

By using the exterior angle property, we can get the following:

p+p-13°=p+40°

=>p=40°+13°

=>p=53°

The value of p is 53°

What are consecutive integers

Consecutive integers are numbers that follow in a particular order, usually just one after the for example, 1, 2, 3,... and so on.

Let the width of the rectangle be represented by x so that the length will be x + 1 as they consecutive integers

The perimeter of the rectangle will have the equation;

x + x + x + 1 + x + 1 = 86 inches

4x + 2 = 86 inches {collect like terms}

4x = (86 - 2) inches {subtract 2 from both sides of the equation}

4x = 84 inches

x = (84/4) inches {divide through by the coefficient of x}

Let x denotes the Number of hours and y denotes the Cost of parking .

Here , x- independent variable

y- dependent variable

Now, rate of change = ( change in y) / ( change in x)

                                  = (14-10)/(3-1) = 2

Here , the rate of change = $ 2 per hour.

Again rate of change =  ( change in y) / ( change in x)

Tip (In $): 6.75

Sales tax: 3.00

The total amount of food (before additional fees): 37. 50

So, to find the amount (in dollars) of the sales tax and tip, we must use this formula:

Amount = whole number * part percent/100

So, plugging in the numbers to the formula, it would look like this:

37.50 * 18 / 100

From the graph, we see that,

x = 0, y = -1

x = 1, y = -4

Now,

The equation in the form of y = A.[tex]2^x[/tex]  + K can be written as,

Taking (0, -1) we get,

-1 = A x 1 + K

-1 = A + K ______(1)

Now,

Taking (1, -4) we get,

-4 = A x 2 + K

-4 = 2A + K _____(2)

From (1) and (2) we get,

A = K - 1 putting in (2) we get,

-4 = 2(K - 1) + K

-4 = 2K - 2 + K

-4 = 3K - 2

3K = -4 + 2

Volume of the cylinder = 1570 cubic inches

Volume of cylinder = π[tex]r^{2}[/tex]h

Where r is the radius of cylinder

h is the height of cylinder

So,

Volume of the cylinder = 1570 cubic inches

=> 1570 = π[tex]r^{2}[/tex]h

=> 1570 = 3.14*[tex]r^{2}[/tex]*5

zero and negative exponents result from applying properties of exponents. for example, zero indicates that the same number of repeated factors of a non-zero base was found in both the numerator and denominator of an expression.

Answers

The question is incomplete , I am answering it with my general knowledge,

Zero exponent

Simplifying an expression with a 0 as the exponent does not need consideration of the base value.

Any non-zero number multiplied by 0 has the value 1.

x0 = 1, where x = 0 and x = 1, 2, 3, and so forth.

Negative exponent

For any positive integer m and non-zero number a,

a⁻ⁿ=1/a⁻ⁿ

This rule states that if the exponent is negative, it can be made positive by writing the same number in the denominator and writing one for the numerator.

When a number is positive, the exponent shows how many times it has been multiplied by itself.

On the other hand, the negative exponent indicates how many times we must divide the base number. The negative exponent, then, tells us how many times to multiply the reciprocal of the base, to put it another way.

There must be no chance that d and e will happen. If the two occurrences cannot coexist, we can infer that they are not independent.

What is probability?

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

What is the probability formula?

P(A) = n(A)/n(S)

Where P(A) is the likelihood that an event "A" will occur and n(A) is the number of positive outcomes. The total number of occurrences in the sample space is denoted by n(S).

We must have a similar probability for both events in order for them to be independent. Because of the table, we may test for independence by knowing the likelihood that e and d will occur. When we are told that occurrences d and e are mutually exclusive, the entire table of values becomes somewhat of a red herring. The chance of d given e and the probability of d given d are both equal to zero if two events are mutually incompatible. There must be no chance that d and e will happen. If the two occurrences cannot coexist, we can infer that they are not independent. There is a chance for it.

What is the probability that out of 125 babies born, at least 50 will be girls? Assume that boys and girls are equally probable, and round your answer to the nearest tenth of a percent.

Answers

When boys and girls are equally likely, the likelihood that at least 50 of 125 infants born will be females is 0.40.

What is probability?

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.

Here,

total number of sample=125

number of girls=50

Probability that out of 125 babies born, at least 50 will be girls,

=50/125

=0.40

The probability that out of 125 babies born, at least 50 will be girls is 0.40 when boys and girls are equally probable.

What is the total area of the walls to be painted?

Answers

The total area of the space will be equal to 175 square meters.

What is the percentage?

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Elizaveta painted 35 square meters of wall space. This represents 20% of the total area.

The total area will be calculated as,

20% of area = 35 square meters

100% of the area = ( 35 x 100) / 20

100% of the area = 175 square meters

Therefore, the total area of the space will be equal to 175 square meters.
