4x + 8y ≤ -24 is the example of linear inequality in two variables.

Linear equations are one-degree equations. It is a straight-line equation. A linear equation with parameters a and b equal to zero has the conventional form ax + by + c = 0.

The graph of a two-variable inequality is the set of points that describe all solutions to the inequality. The coordinate plane is split in half by a boundary line created by a linear inequality, with one-half representing the solutions to the inequality.

It's a line with a shaded side on one side to show which xy pairings are the inequality's solutions.

For example -

Let us take a equation, 4x + 8y ≤ -24

Now, solve the above equation in the form of slope-intercept.

4x + 8y ≤ -24

or, 8y ≤ - 4x - 24

or, y ≤ -(1/2)x - 3

To find the height of an isosceles triangle, we square the length of one of the equal sides and subtract the square of half the base, and the area can be easily calculated if the height  and the base are known. Multiplying the height with the base and dividing it by 2, results in the area of the isosceles triangle.

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.

The time period is T = √[(4π^2mA^2)/mw^2A^2].

In the given question, we have to calculate this time and hence the period.

By conservation of energy :

1/2*mw^2A^2 = 1/2*mv^2+1/2*mw^2x^2

V^2 = w^2(A^2−x^2)

V = w√(A^2-x^2)

dx/dt = w√(A^2-x^2)

[tex]\frac{dx}{\sqrt{A^2-x^2}}[/tex] = w*dt

[tex]\frac{dx}{A\sqrt{(1-(x/A)^2}}[/tex] =w*dt

put (x/A)^2 = v

dx/A=dv

[tex]\int_{0}^{1} \frac{dv}{\sqrt{1-v^2}} = \int_{t=Io}^{t=t}w\times dt[/tex]

[tex][sin^{-1}(1)-sin^{-1}0]=wt[/tex]

π/2=wt

t= π/2w

[∴w=2π/T]

t= πT/2*2* π

t=T/4

Where T is time period

F = -kx

a = -k/m*x

ma = -kx

a = -w^2x

(standard equation of S.H.H)

Answer:

D. 12 hours

Step-by-step explanation:

I am guessing that they want you to find the average time together, or the mean.

Add 18 hours and 6 hours together to get 24 hours.

Since there are 2 groups (2 people) that have an outcome of 18 hours and 6 hours, 24 hours/2 people is a 12 hour average.

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

Therefore, the solution to this problem is  (x - 2)(x + 3) are the factors of p(x) (2x - 5).

An equation is a mathematical statement that is created by connecting two expressions using the equivalent sign. An example of an equation is 2x - 5 = 15. By resolving this equation, we may ascertain that the variable x has a value of 5.

Here,

Given, the polynomial in this case is 2x3 - 3x2 - 17x + 30.

It is necessary to factor the polynomial.

Let p(x) equal 2x3, 3x2, 17x, and 30.

P(xconstant )'s term is 30.

Factors of 30 are equal to 1, 2, 3, 5, 6, 10, 15, and 30.

Consider x = 2.

Replace x = 2 in p. (x),

2(2)³ - 3(2)² - 17(2) + 30 =p(2)

=> 2(8) - 34 - 3(4) + 30

= >16 - 16

= 0

So, x - 2 is a factor of 2x³ - 3x² - 17x + 30.

Now splitting the x² and x terms,

2x³ - 4x² + x² - 2x - 15x + 30= 2x³ - 3x² - 17x + 30

=> x(x - 2) - 15(x - 2) +  2x²(x - 2)

= > (x - 2)  *  (2x² + x - 15)

factoring  2[tex]x^{2}[/tex] + x - 15

= 2[tex]x^{2}[/tex] + 6x - 5x - 15

= - 5(x + 3)  +  2x(x + 3)

The elements in sets are separated by commas so they can be read easily.

Instead of describing the constituents of a set, a set-builder notation describes them. The elements are listed, for instance, in the set {5, 6, 7, 8, 9}. We interpret the collection of all x such that x is a counting number between 4 and 10 as the collection of all x.

In mathematics, a set is a logically arranged group of items that can be represented in either set-builder or roster form. Sets are typically denoted by curly brackets {}; for instance, A = {1, 2, 3, 4} is a set.

The sequence of elements (separated by commas) between the curly braces " and "in mathematics form an unordered group of elements known as a set. For instance, the domesticated animals {cat, cow, dog} , the odd numbers {1, 3, 5, 7, 9} and the alphabets {a, b, c, d, e} are all sets. So they can be read or interpreted easily.

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.

What is a linear equation in two variables?

An equation is said to be a linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Let x number of tickets sold on Friday and y number of tickets sold on Saturday.

By using the given condition,

x + y = 360 ----------(I)

y =3x -------(II)

Put y = 3x in equation (I), we get

x + 3x = 360

4x = 360

  x = 90

As per the rational root theorem, the actual root of the polynomial is  - 5/2

The term polynomial refers the algebraic expression in which the exponents of all variables should be a whole number

Here we have given that  f(x) = 6x⁴ + 5x³ – 33x² – 12x + 20.  and we need to find which is an actual root of f(x).

In order to find the root for the polynomial we have to apply each value as the replacement of x in the polynomial.

And then we have to find in which one makes the polynomial result as zero.

First we have to take the value of x as -5/2, then the polynomial equation be like,

Here we have to substitute x=-5/2, then we get

=> f(-5/2) = 6(-5/2)⁴ + 5(-5/2)³ - 33(-5/2)² - 12(-5/2) + 20

=> f(-5/2) = 6(625/16)-5(125/8)-33(25/4)+30+20

when we simplify this one then we get,

=> f(-5/2)=(1,875-625-1,650+400)/8

=>  f(-5/2)=0/8

Here we know that if we zero by any number we get the result as zero.

Therefore, f(-5/2)=0 then x=-5/2 is a root of f(x)
