The process of checking polynomial division supports the fact that polynomials are closed under multiplication and addition is shown below:

A polynomial is the quotient (with or without a remainder). multiplying this polynomial by the polynomial's divisor We get a polynomial with updated exponents and coefficients, so it's closed under multiplication.

A polynomial is defined as an equation composed of variables, constants, and exponents that are joined together using mathematical operations such as addition, subtraction, multiplication, and division.

If no remainder exists, the dividend is equal to the quotient multiplied by the divisor.

The quotient and divisor, as well as their product, the dividend, are both polynomials.

If there is a residual, it is added to the product of the quotient and divisor.

The polynomial dividend is the sum of the remainder and the product of the quotient and divisor.

The equation of line passes through (-6,1) and has slope 6 will be y=6x+37.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that the line passes through (-6,1) and has a slope of 6,

The equation of line passes through (-6,1) and has slope 6 is found as,

y-y₁=m(x-x₁)

y-1=6(x-(-6)

y-1=6(x+6)

y-1=6x+36

y=6x+36+1

The mean of the first 10 whole numbers is 4.5.

What is mean?

A amount that includes a price intermediate between those of the acute members of some set is known as mean.

Main body:

In this question we have to find the mean of the first 10 whole numbers. Whole numbers are all non-negative integers which start from 0. Now the mean of the first 10 whole numbers will be the mean of numbers from 0 to 9, as the count of numbers from 0-9 is 10. Use this concept to reach the answer.

Mean of numbers is equal to the sum of the numbers divided by the count of the numbers that is

Mean = sum of numbers/ total numbers          …………………….. (1)

To find the mean of the first 10 whole numbers, we will find the sum of numbers from 0 to 9 as 0-9 are the first 10 whole numbers.

So, the sum of the first 10 whole numbers is 0+1+2+3+4+5+6+7+8+9=45.

Now putting the values in equation (1) we get, mean = 45/10 = 4.5

Hence, the mean of the first 10 whole numbers is 4.5.

What do you mean by algebraic expression?

The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it.

Let my present age be x

Age of mine , 20 years ago = x - 20

Age of mine , 10 years ago = x - 10

According to question,

(x - 20) = 13(x - 10)

⇒ x - 20 = 13x - 130

⇒ 13x - x = 130 - 20

⇒ 12x = 110

⇒ x = 110/12

⇒ x = 9.17

Given that f = [tex]x^{2}[/tex]+ [tex]y^{2}[/tex]

Let g = [tex]x^{4}[/tex] + [tex]y^{4}[/tex] = 1296

By Lagrange Multipliers:  grad(f) = λ grad(g)

2x = 4λ[tex]x^{3}[/tex]=> x(2λ[tex]x^{2}[/tex] - 1) = 0

2y = 4λ[tex]y^{3}[/tex] => y(2λ[tex]y^{2}[/tex] - 1) = 0

Now there possible 3 cases :

(i) If x = 0, then   [tex]x^{4}[/tex] + 0 = 1296 => x = ±6.

(ii) If y = 0, then 0 + [tex]y^{4}[/tex]= 1296 => y = ±6

(iii) Otherwise, we have 2λ[tex]x^{2}[/tex] - 1 = 0 = 2λ[tex]y^{2}[/tex] - 1  => λ([tex]x^{2}[/tex] - [tex]y^{2}[/tex]) = 0.

If λ = 0, then both x = 0 and y = 0 and this is not possible since [tex]x^{4}[/tex]+ [tex]y^{4}[/tex]= 1296.

Otherwise,[tex]x^{2}[/tex] = [tex]y^{2}[/tex] ⇒ [tex]x^{4}[/tex] +  [tex]x^{4}[/tex] = 1296 => x = ± [tex]648^{1/4}[/tex]

The exponential growth formula for bacteria growth is P(t) = 8600 [tex](2)^(t/5)[/tex].

What is exponential growth?

     Exponential growth is a pattern of data that exhibits a greater increase over time, resulting in an exponential curve. Exponential is also a mathematical term meaning "with exponents". For example, if you raise a number to the 10th power, the number increases exponentially. Exponential growth is growth that increases at a constant rate.

Here given take Initial number of bacteria = 8600. rate of growth = 2.

It doubles every year. Then doubling time = 5 hours.

Now population growth after t years,

P(t) = Po [tex](2)^(t/5)[/tex]

The principle that individuals will be given only the level of access that is appropriate for their specific job role or function is called Principle of Least Privilege (PoLP)

The IT team will frequently need to re-grant credentials so that users may accomplish certain tasks when businesses choose to revoke all administrative capabilities from business users. For instance, many commercial off-the-shelf (COTS) apps and legacy programmes used in enterprise IT systems need privileges to function. The IT staff needs to restore local administrator access to business users so they can utilise these approved and necessary programmes.

As privileges are rarely removed once they have been granted again, organisations may find that many of their users eventually have local administrator rights once more.A user is only provided the minimal levels of access - or permissions - required to carry out his or her job functions under the principle of least privilege (PoLP), which is a notion in information security. It is widely regarded as a best practise in cybersecurity and is a crucial step in safeguarding privileged access to highly valuable data and assets. Beyond human access, least privilege applies.

Applications, systems, and linked devices that require rights or permissions to carry out a necessary operation can all use the paradigm. Least privilege enforcement makes sure the machine tool only has the minimal access required. A mechanism to centrally store and secure privileged credentials is necessary for least privilege enforcement, combined with adaptable policies that can balance cybersecurity and compliance needs with operational and end-user needs.

The sequence where each word is varied by another by a common ratio is known as a geometric progression or geometric sequence. When we add a constant (which is not zero) to the term before it, the sequence's subsequent term is created. The following symbols stand in for it: a, ar, ar2, ar3, ar4, etc.

Geometric Progression (GP), a form of sequence in mathematics, is a series in which each subsequent term is created by multiplying each preceding term by a set integer, known as a common ratio. A geometric sequence of integers that follows a pattern is another name for this development.

And,

f(n) = 3(5)ⁿ⁻¹

Now,

f(1) = f(1 - 1) + 4

3 = f(0) + 4

⇒ f(0) = 3 - 4 = -1

Here f(0)= -1

and  f(n) = 3(5)ⁿ⁻¹

Now,

f(1) = 3 × (5)¹⁻¹ = 3 × (5)⁰ = 3 × 1 = 3

f(1) = 3

Hence, the first term in both sequences is -1.

Binary is a base-2 number system that represents numbers using the states 0 and 1. It is also possible to refer to it as a true state and a false state. The process for creating a binary number is the same as for creating a regular decimal number.

Negative numbers can be expressed in a variety of ways. Magnitude of the sign is one method. In this technique, the sign is indicated using one bit. Typically, mathematical numbers consist of a sign and a value. While the value denotes the size of the number, the sign shows whether it is positive (+) or negative (-).

Negative binary numbers can be represented in a signed binary number system using the one's complement method. Positive numbers continue to be unchanged in one's complement.

Hence we get the required answer.
