What is a exponent? What is logarithmic function?

In mathematics, if -

then -

[n] is called exponent

[x] is called base.

Logarithm is the inverse function to exponentiation. That means the logarithm of a number [x] to the base [b] is the exponent to which [b] must be raised, to produce [x]. We can write -

[tex]y = log_{e}x[/tex]

We have the function as -

f(x) = x³

Refer to the graph of the function in the modified form. The function after being translated is same as the one given in the question. The function after translation is -

c. Would the sum of the interior angles of a triangle in this type of geometry be different from those of triangle in Euclidean geometry? Explain.

Answers

The fact that the sum of the interior angles of a triangle add up to 180 is equivalent to the parallel postulate. Therefore, the sum of the interior angles of a triangle in this type of geometry be different from those of triangle in Euclidean geometry.

How to illustrate the information?

There is only one parallel to the given line in Riemannian geometry. A straight line of finite length that can be continued endlessly is the second postulate of Euclid.

One of the non-Euclidean geometries that entirely rejects the validity of Euclid's fifth postulate and alters his second postulate is Riemannian geometry, commonly known as elliptic geometry. The fifth postulate of Euclid states that there is only one line that passes through a point that is not on a particular line and is parallel to that line.

In this case, the angles won't change as it's always equal

Answers

a) for given functions f(x) = 8x and g(x) = 12x + 3,

(f g)(x) = 96x² + 24x

b) for functions f(x)= 14 and g(x)= 3 - 12x,

f(x) • g(x) = 42 - 168x

In this question, we have been given two functions.

We need to find the given function.

a) f(x) = 8x and g(x) = 12x + 3

To find (f g)(x)

We know that, the product of functions f(x) and g(x) is:

(f g)(x) = f(x) . g(x)

(f g)(x) = (8x) (12x + 3)

(f g)(x) = 96x² + 24x

So, for given functions f(x) = 8x and g(x) = 12x + 3,

(f g)(x) = 96x² + 24x

b) f(x)= 14 and g(x)= 3 - 12x

To find f(x) • g(x)

f(x) • g(x) = (14) . (3 - 12x)

f(x) • g(x) = 42 - 168x

So, for functions f(x)= 14 and g(x)= 3 - 12x,

f(x) • g(x) = 42 - 168x

Therefore, a) for given functions f(x) = 8x and g(x) = 12x + 3,

(f g)(x) = 96x² + 24x

b) for functions f(x)= 14 and g(x)= 3 - 12x,

f(x) • g(x) = 42 - 168x

statistically speaking, the value that describes how far off an average could be is called the error.

Answers

The accuracy of a survey estimate refers to the closeness of the estimate to the true population value. Where there is a discrepancy between the value of the survey estimate and the true population value, the difference between the two is referred to as the error of the survey estimate.

The total error of the survey estimate results from the two types of error:

sampling error, which arises when only a part of the population is used to represent the whole population; and

the non-sampling error which can occur at any stage of a sample survey and can also occur with censuses. Sampling error can be measured mathematically whereas measuring non-sampling error can be difficult.

Sampling error is affected by a number of factors including sample size, sample design, the sampling fraction, and the variability within the population. In general, larger sample sizes decrease the sampling error, however, this decrease is not directly proportional.

The most commonly used measure of sampling error is called the standard error (SE). The standard error is a measure of the spread of estimates around the "true value". In practice, only one estimate is available, so the standard error can not be calculated directly.

Answers

An AABA form can be repeated to create a larger form; when b and a are repeated after the first AABA, it is called a "partial reprise". The BA or ABA sections of the AABA structure are repeated in the majority of partial reprises.

What is reprise?

The term "reprise" is derived from the French word "repris," which means "act of taking back." The word is also derived from the Latin word "reprendre," which means "taken up again." The term is typically used in music, but it can refer to any continuation of an action.

Various uses of reprise in musics are given below-

Music that is classical: Reprises are most prevalent in the sonata form's recapitulation section.Music for films: Characters and settings are given specific motifs by film composers. These motifs reappear throughout the film.Theatrical musicals: Repetition is used in musical theater as scenarios develop and characters reappear.Jazz: Repetition is used by jazz musicians in a head-solo-head music format. The players begin with a pre-composed segment labeled the head, then break off towards solos influenced by that head, & finish with a reprise of a initial theme.Rock and pop: Pop and rock are created on repetition, and whenever a tune, vocal hook, or entire chorus is repeated, we can call it a reprise.

Every term in a geometric sequence has a fixed relationship to the term before it. A popular representation of a geometric sequence containing the initial term a, the common ratio r, and a finite number of terms is  a, a*r, a*r₂, ..., a*r(ₙ₋₁).

According to given value;

The area of first triangle =(1)*(1)*(1/2)

                                         =1/2

The area of second triangle =

(1/2)*(1/2)

                                                        =(1/2)²

The area of third triangle =(1/2)²*(1/2)

                                                   =(1/2)³

The area of [tex]n^{th}[/tex] triangle = (1/2)ⁿso the total area of all triangle is formed;

The condition  [tex]f^{\prime}(2)[/tex] = 0 to form a subspace of  [tex]\mathbb{R}^{(0,3)}[/tex] is that f ∈ S is that otherwise, S wouldn't be closed under addition and thus would not be a subspace of  [tex]\mathbb{R}^{(0,3)}[/tex].

What is additive identity?

An identity element (like 0 in the collective of whole numbers under operation of addition) that leaves unaffected any element that it is added in a provided mathematical system.

Now, for the given question.

I'd just like to comment on the paragraph about intuition as well as the additive identity: That instinct is incorrect.

First, we could perhaps define a object that we need to confirm is a subspace of [tex]\mathbb{R}^{(0,3)}[/tex] in a more precise manner than the translation in which it is initially presented. We want to look at a set, S.

Where,

[tex]S=\left\{x, f \mid 0 < x < 3, f \in \mathbb{R}^{(0,3)} \wedge f^{\prime}(x)=0\right\}[/tex]

We are specifically tasked with having to prove the restriction just on derivative of f, which is best accomplished in the manner made reference.

The fact that S, as described above, describes a functional space explains why my initial intuition about problem is ultimately incorrect. I was hindering myself by viewing it solely as a geometric space.

As a result, I missed the fact that zero function (the additive identity in such a functional space) is indeed a natural member of S.

Diana usually drives at an average rate of 30 mph. If Diana drives at an average rate of x mph, how long will it take her to get to Tony's house?

Answers

Diana drives for two hours at a speed of 30 mph, covering a total distance of 60 miles to get to Tony's house.

What exactly is average speed?Average speed is described as the ratio of a body's total distance traveled to the total time required to reach its destination.The total distance covered by the element in a given time interval is the average speed. A scalar quantity is average speed. It is depicted by magnitude and lacks direction.

Diana drives for two hours at a speed of 30 miles per hour.

To calculate the distance she will travel

Average speed = total distance / total time

Total time = two hours and the average speed = 30 mph

30 mph = total distance / two hours

Total distance = 30 × 2

Total distance = 60 miles

Therefore, Diana drives for 2 hours at a speed of 30 mph, so the total distance traveled is 60 miles to get to Tony's house.
