What is the value of a function on a Variable?
A real-valued function of a real variable is a function that takes as input a real number, commonly represented by the variable x, for producing another real number, the value of the function, commonly denoted f(x).
What is Factor?
A factor of polynomial P(x) is any polynomial that divides evenly into P(x).
How to find out the value of r(x)?
Given r(x)=x^3-4x^2+4x-6,
Put x = 2 ,
r(2)=2^3-4(2)^2+4(2)-6
r(2)=8-16+8-6
r(2)=-6
As we see that x=2 is not equal to zero,
implies x-2 does not divide r(x) evenly.
thus x-2 is not a factor of given r(x).

If the bond angle between two adjacent hybrid orbitals is 120°, which is the hybridization?.
If the bond angle between two adjacent hybrid orbitals is 120° the hybridization is Sp2 hybridization .
Hybridization is a theory that is used to explain certain molecular geometries that would have not been possible otherwise.
sp2 hybridization
There are other ways to combine the orbitals than sp3 hybridization when an excited state carbon atom is produced. As opposed to the three p orbitals in the sp3 hybridization, the s orbital only interacts with two p orbitals in the sp2 hybridization. As a result, three orbitals are combined to create three hybrid orbitals, also known as sp2 hybrid orbitals.

The decimal numbers that have an even number in the tenths place, an odd number in the hundredths place, and a prime number in the thousandths place include 0.237, 0.893, 0.475, and 0.652.
What is the definition of an even number?An even number is any number that can be divided exactly by two. Even numbers always have a last digit of 0, 2, 4, 6, or 8. Even numbers include 2, 4, 6, 8, 10, 12, 14, and 16.
Odd numbers are those that cannot be divided evenly by two. It cannot be evenly divided into two separate integers. When we divide an odd number by 2, we get a remainder. Odd numbers include 1, 3, 5, 7, and so on.
A prime number is a natural number greater than one that cannot be calculated as the product of two smaller natural numbers. A composite number is a natural number greater than one that is not prime. 5 is prime, for example, because the only ways to write it as a product, 1 5 or 5 1, involve 5 itself.
A prime number is a whole number greater than one with only the number one and itself as factors. A factor is a whole number that can be divided into other numbers evenly.

Find the 70th term of the arithmetic sequence
Answer:
753
Step-by-step explanation:
Arithmetic sequences are sequences that change by a constant factor.
Explicit Rule
The formula that describes an arithmetic sequence is called the "explicit rule". This formula is f(x) = f(1) + d(x-1). Sometimes the rule will be written with [tex]a_{n}[/tex] instead of f(x) but the equations are still the same.
In this equation, f(1) is the first term of the sequence, d is the common difference, and x is the term. The common difference is the factor that the sequence changes by.
Setting Up the Equation
To set up the equation, we need to find f(1) and d.
The first term, f(1), is directly given to us in the equation. The first term written is -6, so f(1)=-6.
It is slightly more difficult to find d. But, one easy way to find d is by subtracting terms. Take the second term, 5, and subtract the first term, -6.
5 - (-6) = 11So, d = 11. Each term in the sequence increases by 11.
The final equation is f(x) = -6 + 11(x-1).
Finding the 70th Term
Now, all we have to do is plug 70 in for x. To find any term in the sequence, all you have to do is plug the term number in for x.
f(70) = -6 + 11(70-1)f(70) = 753The 70th term in the sequence is 753.
Which ordered pair is a solution to the equation?

A Only (2, 1)
B Only (5, -5)
C Both (2, 1) and (5,-5)
D Neither
Answer: Neither (5/2, 0)
Step-by-step explanation:
-4x + 7 = 2y - 3
+3 +3
2y = -4x + 10
(Divide both sides by 2)
y = -2x +5
—————————————————
-4x + 7 = 2(-4x + 10) - 3
-4x + 7 = -8x + 20 - 3
-4x + 7 = -8x + 17
+8x -7 +8x -7
8x - 4x = 17 - 7
4x = 10
(Divide both sides by 4)
x = 5/2
—————————————
y = -2(5/2) + 5
y = -5 + 5
y = 0
——————————
Check Work:
-4x + 7 = 2y - 3
-4(5/2) + 7 = 2(0) -3
-10 + 7 = 0 - 3

theo started watching a movie at 19:30 The movie was 1 hour 56 minutes long,but part-way through he paused it for 12 minutes what was the time the movie finished
Answer: 21:38 on a 24 hour clock and 9:38 on a 12 hour clock
Step-by-step explanation:
So if Theo started the movie at 7:30 and the movie was 1 hour 56 minutes, and he paused half way for 12 minutes, we can conclude that the total time taken to watch the movie/break was 2 hours and 8 minutes.
Now we just add that time
7:30 + 2 hours and 8 minutes = 9:38
On a 24 hour clock the answer would be 21:38
pls help :( The table shows the sizes of Farmer Reuben's fields. Use the table and a separate sheet of paper to help you answer each question.
The areas of each of Reuben's fields are given as follows:
Corn Field: 24,000 square feet.Wheat Field: 140,000 square feet.Barley Field: 40,000 square feet.Hence the total area of all of Reuben's fields is given as follows:
204,000 square feet.
How to obtain the areas of the fields?The areas of the fields is given by the multiplication of each of the dimensions of the field, as the fields have a rectangular format.
Then the total area is obtained as the sum of the areas of each field.
The dimensions of each field are given as follows, from the table given by the image at the end of the answer:
Corn Field: 400 feet by 60 feet.Wheat Field: 700 feet by 200 feet.Barley Field: 200 feet by 200 feet.Hence the areas of each of the fields are given as follows:
Corn Field: 400 x 60 = 24,000 square feet.Wheat Field: 700 x 200 = 140,000 square feet.Barley Field: 200 x 200 = 40,000 square feet.Then the total area is given as follows:
24,000 + 140,000 + 40,000 = 204,000 square feet.

Let f(x) = 6x. The graph of f(x) is transformed into the graph of g(x) by a vertical compresion of 1/2 and a translation of 4 units up.
The equation for of graph of g(x) = 3x-4
Functionsy = afb(x +c) + d
where a represent the vertical stretch
b represent the horizontal stretch
c represent the horizontal translation
d represent the vertical translation
from the equation we are given g(x) has a vertical stretch and a vertical translation ( y-axis represent up and down therefore its a vertical translation)
The equation of g(x) is:
g (x) = 1/2(6x) - 4
g(x) = 3x-4
Therefore, the equation for of g(x) = 3x-4

Determine if the subset of R^2 consisting of vectors of the form [a b], where a + b = 1 is a subspace. Select true or false for each statement. This set is closed under scalar multiplications This set is a subspace This set is closed under vector addition The set contains the zero vector
If the subset of R^2 consisting of vectors of the form [a b], where a + b = 1 is a subspace. The statement: This set is closed under scalar multiplications This set is a subspace .This set is closed under vector addition The set contains the zero vector is False.
Vector:A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity.
Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight. A quantity or phenomenon that exhibits magnitude only, with no specific direction, is called a Scalar . Examples of scalars include speed, mass, electrical resistance, and hard-drive storage capacity.
Scalar Multiplication:Scalar multiplication is the multiplication of a vector by a scalar (where the product is a vector), and is to be distinguished from inner product of two vectors (where the product is a scalar).
For quaternion scalars and matrices:
λ = 2 A = [tex]\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right][/tex]
2A = 2[tex]\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right][/tex]
= [tex]\left[\begin{array}{ccc}2a&2b\\2c&2d\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}a.2&b.2\\c.2&d.2\\\end{array}\right][/tex]
= [tex]\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right][/tex] × 2 = A2
Subspace:In mathematics, and more specifically in linear algebra, a linear subspace, also known as a vector subspace is a vector space that is a subset of some larger vector space. A linear subspace is usually simply called a subspace when the context serves to distinguish it from other types of subspaces.
