The acceleration y, in meters per second squared, of an object after x seconds is given by y =. During the first 10 seconds, over which intervals is the acceleration increasing?.

The standard deviation of the given population is 7.72.

What is population?

All of the components of the data set are included in the population, as are parameters like mean and standard deviation that can be used to measure the population. The term "population" denotes the complete group of individuals, things, events, etc.

Given data,

                   53, 36, 36, 44, 31

We know that,

Standard deviation of a population is given by :

= √ [ ∑ ( X - ц )²/N

Where, X = each data point

            ц = mean of data of population

            N = No. of data points in population = 5

We need mean,

So, mean of data of population = (53 + 36 +36 +44 + 31)/5

                                                    = 40.

So, By applying formula :

SD = √ [ ∑ ( X - ц )²/N ]

      = √1 / 5 [ (40-53)² + (40-36)² + (40-36)² + (40-44)² + (40-31)²

      = √ ( 169 + 16 + 16 + 16 + 81 )/5

      = √298/5

      =7.72.

Answer:

n = -56

Step-by-step explanation:

1/8n=−7

1/8 * n = −7

n * 1/8 = −7

n/8 = −7

8 * n/8 = -7 * 8 ==> multiply each side by 8 to isolate n and remove fractions

n = -56

Answer:

[tex]\displaystyle{x=\dfrac{\pi}{2}n}[/tex] for n is any integers

Step-by-step explanation:

To know the asymptotes, first, we must know values of x that we turn y-value into an undefined value.

We know that:

[tex]\displaystyle{\cot x = \dfrac{1}{\tan x}}[/tex]

Now we have to find value of x that turns the identity above into undefined value, and that is [tex]\displaystyle{x=n\pi}[/tex] where n is any integers. (This gives 1/0 for all x = nπ)

Therefore, a function [tex]\displaystyle{\cot x}[/tex] has asymptote lines at [tex]\displaystyle{x=n \pi}[/tex] for n is integers.

If we consider the given problem:

[tex]\displaystyle{y=\dfrac{1}{3}\cot 2x}[/tex]

We have to find values of x that turn y-value undefined. We know that [tex]\displaystyle{x=n\pi}[/tex] is asymptotes for [tex]\displaystyle{\cot x}[/tex]. Therefore, [tex]\displaystyle{2x=n\pi}[/tex] has to be asymptotes for [tex]\displaystyle{y=\dfrac{1}{3}\cot 2x}[/tex].

Hence, the asymptotes occur at [tex]\displaystyle{x=\dfrac{\pi}{2}n}[/tex] by solving the equation and for n is any integers.

The interest on Ethan's CD account will be $700 * 1.8% = 12.6$ dollars after one year. Since the CD earns 1.8% interest each year, the interest will be the same amount each year, so the total interest on the CD after 6 years will be $12.6 * 6 = 75.6$ dollars. This means that the CD will be worth $700 + 75.6 = $775.6$ after 6 years.

The sample space of rolling a 6 sided number cube is the set of all possible outcomes of rolling the number cube. The sample space for a 6 sided number cube is the set of numbers 1,2,3,4,5, and 6.

When rolling a 6 sided number cube, the sample space is the set of all possible outcomes, which are the numbers from 1 to 6. This means that the sample space includes each of the six numbers, with no bias towards any particular number. Each of the six numbers has an equal chance of being obtained when rolling the number cube.

The sample space of a 6 sided number cube is also known as a discrete sample space, since all of the possible outcomes are predetermined and known. The sample space of a 6 sided number cube is finite and can be easily calculated by listing all the possible outcomes. Since there are 6 possible outcomes, the sample space consists of 6 elements.

The sample space of a 6 sided number cube can be easily visualized by imagining a six-sided die being rolled and each side being labeled with a number from 1 to 6. This demonstrates that the sample space of a 6 sided number cube is a discrete sample space, and each of the six numbers has an equal chance of being obtained.

For x = 5 and y = 3 the given triangles are congruent.

What is congruent triangles?

In any orientation, two triangles are said to be congruent if their three sides and three angles are equal.

Therefore, if two triangles have the same number of sides on each side, they are said to be congruent. Additionally, we can determine that they are congruent if we have a side, an angle between the sides, and then another side that is congruent, in that order: side, angle, side.

Let the given triangles are congruent.

So, their sides are equal.

⇒ x = y + 2         ..(1)

 3y = x + 4         ..(2)

Plug value of x in equation (2)

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

As per the given angle QRS.

The length of QS = 2 grids and RS = 3 grids.

By dilated by 2 scale factor.

The length QS must become 2 x 2 = 4 grids and RS by 3 x 2 = 6 grids.

The multiplicity of a root of a polynomial can be determined by the factorization of the polynomial.

If a root is repeated multiple times, then this root is said to have a higher multiplicity. For example, if a polynomial has the form a(x-r)^2, then the multiplicity of root r is 2. This is because the polynomial can be written as a(x-r)(x-r), and the root r is repeated twice.

To calculate the multiplicity of a root, the polynomial must be factored into its linear factors. The multiplicity of each root is then equal to the power of the corresponding linear factor. For example, if a polynomial is factored into (x-r)^3(x-s), the multiplicity of root r is 3 and the multiplicity of root s is 1.

In general, if a polynomial is written in the form [tex]a*(x-r1)^k1*(x-r2)^k2*...*(x-rn)^kn[/tex], then the multiplicity of root ri is ki. Therefore, the multiplicity of the roots can be calculated by factoring the polynomial and finding the power of the linear factors.

An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language.

A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.  

The most popular equations are algebraic equations or expressions, in which letters are used as variables. Variables are placeholders that can assume any value. They can also be referred to as unknowns. You must solve for the correct value of the variable to make the equation true.

Let us look at an example to understand.

4x + 2x = 12

The letter x is the variable. You must find the value of x. Finding this value will make the right-hand side of the equation equal to the left-hand side. Let's solve this together.

In this case, since both variables are the same, you can add the values on the left-hand side.

6x = 12

Now, we divide both sides by the value of '6', which will help us solve for x. Consider this to be a way to unravel the equation. Also, remember that whatever is done to one side must be done to the other.

x = 2

The number of days when the two companies will have the same number of followers is 380 days.

The first step is to form linear functions that represent the information of the two companies. The form of the functions is:

The linear function that represents the online followers for the first company is:

Total followers = 95,000 + 100d

The linear function that represents the online followers for the second company is: Total followers = 350d

When the companies have the same number of followers the two above equations would be equal 95,000 + 100d = 350d

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. When two quantities are equal, we use the sign "=," and when they are not equal, we use the symbol "," which stands for "not equal." The first value may be greater than (>), less than (<), greater than equal to (>=), or less than equal to (<=) the second value if the two values are not equal.
