The coefficient of the second term, 6x⁴, is 6.

The terms of the polynomial are:

-4y⁵, 6x⁴, 9w³, -4w, -1

The coefficient of the second term, which is 6x⁴, we look at the number in front of the variable term.

The coefficient is 6.

Therefore, the list of terms is:

-4y⁵, 6x⁴, 9w³, -4w, -1

Each term represents a separate component of the polynomial, where the variable is raised to a certain power and multiplied by its coefficient.

The coefficients indicate the scalar value by which each term is multiplied.

The polynomial's terms are -4y5, 6x4, 9w3, -4w, and -1.

Looking at the number in front of the variable term, we can determine the second term's coefficient, which is 6x4.

There is a 6 coefficient.

As a result, the terms are as follows: -4y5, 6x4, 9w3, -4w, and -1.

Each term represents a different part of the polynomial, where the variable is multiplied by its coefficient and raised to a given power.

The scalar value by which each phrase is multiplied is shown by the coefficients.

Yes, it is possible for an object to have zero momentum. Momentum is defined as function the product of mass and velocity, so an object with zero mass or zero velocity will have zero momentum.

Momentum is a physical property of an object that is equal to the product of its mass and velocity. It is measured in kilogram meters per second (kg m/s) and is a vector quantity, meaning it has both magnitude and direction. In order for an object to have zero momentum, it must have either zero mass or zero velocity. An object with zero mass will always have zero momentum regardless of its velocity, while an object with zero velocity will only have zero momentum if its mass is also zero. An object with nonzero mass but zero velocity still has nonzero momentum if its mass is not zero. Therefore, it is possible for an object to have zero momentum.

180 = inner + outer = 48 + outer

outer = 132°

the exterior angle is 132°.

Answer:   the domain of f/g is every real number except 1 which can be conventionally expressed as {(x,y): x ∈ R, x ≠ 1} OR (-∞ ≤ x < 1) ∩ (1< x ≤ ∞) OR x ∈ R; x ≠ 1.

Step-by-step explanation:

since f(x) = x + 4 and g(x) = x -  1

then f/g = x + 4/x - 1

the denominator of a function cannot be zero since a fraction with a denominator of zero is undefined.

∴  x - 1 ≠ 0

the value of x when g(x) = 0 is

       x - 1 = 0

       x = 1

∴ x ≠ 1

Therefore the domain of f/g is every real number except 1 which can be conventionally expressed as {(x,y): x ∈ R, x ≠ 1} OR (-∞ ≤ x < 1) ∩ (1< x ≤ ∞) OR x ∈ R; x ≠ 1.

The simplified form of the expression 4x(x + 1) − (3x − 8)(x + 4) is -3x^2 - 4x - 32.

To simplify the expression 4x(x + 1) − (3x − 8)(x + 4), we can expand the parentheses and combine like terms.

Expanding the first term, we get 4x^2 + 4x.

Expanding the second term, we have -(3x)(x) - (3x)(4) - (-8)(x) - (-8)(4), which simplifies to -3x^2 - 12x - (-8x) - (-32), further simplifying to -3x^2 - 12x + 8x - 32.

Combining like terms, we obtain -3x^2 - 4x - 32.

The conjecture is true for all trees.

To prove this conjecture by induction, we will use the following statement as our induction hypothesis:

Induction Hypothesis: For any tree with k vertices, the sum of the degrees of the vertices is equal to twice the number of edges.

Base case: For a tree with 1 vertex, the sum of the degrees of the vertices is equal to the degree of that vertex, which is 1. The number of edges is also 1 (since it is a tree with only one vertex and no edges). Thus, the sum of the degrees of the vertices is equal to twice the number of edges, so the induction hypothesis holds for the base case.

Inductive step: Now suppose that the induction hypothesis holds for all trees with k vertices, and consider an arbitrary tree with k+1 vertices. Let v be a leaf vertex in this tree, and let u be its parent. We can "cut off" the leaf vertex v by deleting it and the edge (u,v) connecting it to the tree. This leaves us with a tree with k vertices, which satisfies the induction hypothesis by assumption.

Now, let's regrow the leaf vertex v by adding it back to the tree and connecting it to a new parent w. This increases the sum of the degrees of the vertices by 1 (since the degree of v increases from 0 to 1) and increases the number of edges by 1 (since we have added a new edge (w,v)). Thus, the sum of the degrees of the vertices is still equal to twice the number of edges in the modified tree with k+1 vertices. This shows that the induction hypothesis holds for the tree with k+1 vertices, completing the inductive step.

By the principle of mathematical induction, we can conclude that the induction hypothesis holds for all trees with any number of vertices. In other words, the conjecture is true for all trees.

The length of line having mid point B ⇒  7x - 2.

Given that,

B is the mid point of AC

And also given that

length of segment AB = 2x+5

And length of segment BC = 5x - 7

A straight path established by linking a group of points in a plane is known as a line. It is a one-dimensional form with only a length and no width or height. A line can extend indefinitely in both ends in opposite directions. To indicate a line, we can use upper case characters.

Now since B is the mid point of AC,

So, The line AC is sum of the line segment AB and line segment BC.

Therefore,

AC = AB+BC

The percentage population increase from 2001 to 2011 is 50%.

To calculate the percentage population increase from 2001 to 2011, you need the population figures for both years. Let's assume the population in 2001 was 100,000 and in 2011 it was 150,000.

The formula to calculate the percentage increase is:

Percentage Increase = ((New Value - Old Value) / Old Value) * 100

Plugging in the values:

Percentage Increase = ((150,000 - 100,000) / 100,000) * 100 = (50,000 / 100,000) * 100 = 0.5 * 100 = 50%

Therefore, the percentage population increase from 2001 to 2011 is 50%.

Please note that the actual population figures for the respective years need to be used in the calculation to obtain an accurate result. The example above is for illustrative purposes.

By the concept of function, the value of g(x) obtained is

g(x) = 3f(x) is the required function

What is a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Here, from the graph, it can be seen that

g(1) = 3 and g(-1) = 3

Let g(x) = \(kx^2\)

Answer:

An equation is a proposition of two expressions that are equal.

Step-by-step explanation:

Therefore, the number of sides in this certain regular polygon is 10.

In a certain regular polygon, the measure of each interior angle is four times the measure of each exterior angle. This means that the interior angle and the exterior angle are supplementary, or add up to 180 degrees. We can use this information to create an equation and solve for the number of sides in the regular polygon.

Let x be the measure of the exterior angle and 4x be the measure of the interior angle. Then we have:

x + 4x = 180

5x = 180

x = 36

Now, we know that the sum of the exterior angles in a regular polygon is always 360 degrees. So we can use this information to find the number of sides:

360/x = 360/36 = 10

Therefore, the number of sides in this certain regular polygon is 10.
