Use the unique factorization for the integers' theorem (Section 4.3) and the definition of logarithm to prove that log3 (7) is irrational.

Answers

Answer 1

It is demonstrated that log3 (7) is irrational using unique factorization for integers theorem and the definition of logarithm.

Explain the term  unique factorization theorem?Every integer bigger than 1 is either a prime number by itself or the result of a singular combination of prime numbers, based on the fundamental theorem of arithmetic (FTA), Often known as the unique factorization theorem or even the unique-prime-factorization theorem.

If a contradiction is rational, then log3(7) = a/b for some a,b∈R .

In which, b≠0 will be true.

As a result, 7 = 3ᵃ/ᵇ according to the definition of logarithms.

7 = 1*7 is unique according to the unique factorization theorem.

Thus, it is demonstrated that log3 (7) is irrational using unique factorization for integers theorem and the definition of logarithm.

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°

For each system of equations, which operation will eliminate one of the variable? 2x+7y=32 and 2x+y=8

Answers

By subtraction, the variable x will eliminate and we will find out the value of y in the given system of equations.

What is the equation?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

The equation must be constrained with some constraints.

As per the given system of equations,

2x + 7y = 32 and 2x + y = 8

Subtract both equations from each other,

(2x + 7y) - (2x + y) = 32 - 8

2x + 7y - 2x - y = 24

2x - 2x + 7y - y = 24

6y = 24

y = 4

Answers

The rate of change is not constant.

What is rate of change ?

A rate of change is a measurement of how one quantity alters in proportion to another. The dependent variable y must be present if independent variable x is. rate of change = y-to-x conversion of change. Change rates may be positive or negative.

We know that the rate of change in a function is given by :-

(change in dependent variable) / (change in independent variable)

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)

                                    = (16-14)/(5-3) = 1

Here , the rate of change = $ 1 per hour.

What is volume ?

A three-dimensional space's occupied volume is measured. It is frequently expressed as a numerical value using SI-derived units, other imperial units, or US customary units. Volume definition and length definition are connected.

Here,

The volume of the cylinder is 1570 cubic inches

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

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

=> 500=[tex]r^{2}[/tex]  *5

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.

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.

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

y = [tex]2^x[/tex]

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

3K = -2

K = -2/3

Now,

A = K - 1

A = -2/3 - 1

A = (-2 - 3) / 3

A = -5/3

Now,

The equation is y = (-5/3) . [tex]2^x[/tex] - (2/3)

What was
the amount, in dollars, of the sales tax?
What was the total amount the group paid,
including tax and tip?

Answers

Answer:

The total amount of the sales tax: $3.00

The total amount paid: $47.25

Step-by-step explanation:

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
That is how to find the tip, you would do the same to find the sales tax. Then, when you get both amounts, you add them to 37.50 (the total before the fees) and get $47.25.

What is rigid motion?

A geometric figure is moved by rigid motions, but its size and shape remain unchanged. It generates visuals that make sense.

Rigid transformation comes in four different varieties.

1. translate 2. reflect. 3. Rotation 4. Gliding reflection

Here,

We have a series of rigid motion maps ΔNEM  onto ΔCDE.

We have to find the correct statement, so we concluded that all the corresponding pairs of angles and sides of ΔNEM and ΔCDE are congruent.

Hence, ΔNEM and ΔCDE are congruent.

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.
