What type of function is x 3?
On observing the provided question, we can say that the the provided equation f(x) = [tex]x^3[/tex] is the basic cubic function.
What is function?An statement, rule, or law in mathematics that specifies the connection between an independent variable and a dependent variable (the dependent variable). A relationship between a group of inputs and one output each is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. Y=X2 is an illustration of this. You only receive one output for y if you enter anything for x. The fact that x is the input value leads us to argue that y is a function of x.

Find the distance between the two points (-4,1) and (4,5)
By using the formula for the distance between two points we will see that the distance between the two points is √80 is 8.9
How to calculate the distance between the two points (-4,1) and (4,5)?The length of the line connecting two places represents the distance between them. Subtracting the different coordinates will reveal the distance if the two points are on the same horizontal or vertical line.
Learn how to apply the Pythagorean theorem to find the distance between two points using the distance formula. The Pythagorean theorem can be rewritten as d=(((x 2-x 1)2+(y 2-y 1)2) to calculate the separation between any two locations.
The general formula for the distance between two points (a, b) and (c, d) is:
Distance = √[(a-d)²+(b - c)²]
In this case, we have the points (-4,1) and (4,5), replacing that in the above formula we get:
Distance = √[(-4-4)²+(1-5)²]
= √80
=8.9
Therefore the distance between the two points (-4,1) and (4,5) is 8.9

How to solve 4x 5y 20?
The solution to 4x 5y 20 is 4x + 5y = 20. This can be solved by subtracting 5y from both sides of the equation, giving 4x = 20 - 5y, and then dividing both sides of the equation by 4, giving x = (20 - 5y) / 4.
4x 5y 20 is not an equation and thus cannot be solved. However, if you are looking to find the product of 4x and 5y, then the answer would be 100xy. To calculate this, you must multiply 4x by 5y. This will give you 20x + 20y, which can be simplified to 100xy. To make sure that you reach the correct answer, it is recommended to double check your work. This can be done by taking the inverse of the equation, which would be dividing 100xy by 4x and 5y. If done correctly, you will end up with the same numbers you started with: 4x and 5y.

What does multiplicity mean in math?
The phrase "number of values for which a certain condition holds" is referred to as multiplicity. The phrase, for instance, can be used to describe the magnitude of the totient valence function or the frequency with which a given polynomial equation has a root at a specific location.
Let z_0 be a root of a function f, and let n be the least positive integer n such that f^((n))(z_0)!=0. Then the power series of f about z_0 begins with the nth term,
f(z)=sum_(j=n)^infty1/(j!)(partial^jf)/(partialz^j)|_(z=z_0)(z-z_0)^j,
and f is said to have a root of multiplicity (or "order") n. If n=1, the root is called a simple root '
The multiplicity of a member of a multiset in mathematics is the number of times the member appears in the multiset. The multiplicity of a root, for instance, is how many times a given polynomial has a root at a particular point.
It's crucial to understand the concept of multiplicity in order to correctly count without mentioning exceptions (for example, double roots counted twice). Thus, "counted with multiplicity" is used.
This can be highlighted by counting the number of different elements, as in "the number of separate roots," if multiplicity is disregarded. However, multiplicity is always taken into account when a set (as opposed to a multiset) is established, therefore the word "different" is not necessary.
Hence ,Multiplicity means the quality or state of being multiple or various. and
the number of components in a system (such as a multiplet or a group of energy levels)

find the area of the region enclosed by the inner loop of the curve. r = 4 + 8 sin θ
The area of the region enclosed by the inner loop of the curve is 4π/3.
The term area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Here we have Given the following values,
r = 4 + 8 sin (θ)
Now, we have to substitute the value of r = 0, then we get
⇒ 0 = 4 + 8 sin (θ)
⇒ 8 sin (θ) = -4
⇒ sin θ = -1/2
⇒ θ = -π/6
Therefore, the limit lies in the interval -π/6 to + π/6
Now, the value of Area of polar region is calculated as,
=> A = ∫
Now, by Substituting the values
A=∫π/6−π/6 (4 + 8 sin (θ)) dθ
When we simplify this one then we get the value as,
=> A = 8 [θ + 1/6 sin6θ]
Apply the limit value, then we get

An employee at a toy store wants to put as many teddy bears as she can on a display. Each teddy bear weighs 1/4 pounds. The display can hold a maximum of 14 pounds. How many teddy bears can the employee put on the display?
Brainliest!!!!!
40 POINTS!!!!!!!!!!!!!
Answer:
56 teddy bears
Step-by-step explanation:
If each teddy bear weighs 1/4 pounds, then the total weight of teddy bears that can be put on the display is 1/4 pounds * X teddy bears, where X is the number of teddy bears.
The maximum weight the display can hold is 14 pounds, so we need to find the value of X that satisfies the equation: 1/4 pounds * X teddy bears = 14 pounds.
Dividing both sides of the equation by 1/4 pounds, we get: X teddy bears = 14 pounds / 1/4 pounds = 56 teddy bears.
Therefore, the employee can put 56 teddy bears on the display.
Answer: 56 teddy bears on the display.
Step-by-step explanation: We can find the maximum number of teddy bears that can be put on the display by dividing the maximum weight of the display by the weight of each teddy bear. Since each teddy bear weighs 1/4 pounds and the display can hold 14 pounds, we can put a maximum of 14 / (1/4) = <<14/(1/4)=56>>56 teddy bears on display.

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
2x² + kx + k = 0 be equation (1)
And , the roots of the equation are equal
So , when the discriminant is zero we get just one real solution
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
( b² - 4ac ) = 0
Substituting the values in the equation , we get
k² - 4 ( 2 ) ( k ) = 0
On simplifying the equation , we get

The equation of a straight line that is perpendicular to the line y = x is the line y = −x .
E.g. Take the line y = 2x.
