The x intercepts are 0, 1, -2, 2.
What is intercepts?
The term "intercept" refers to the x- and y-intercepts of of a given equation. The x-intercept is the point at which a line crosses the x-axis and the y-intercept is the point at which a line crosses the y-axis.
In the linear equation, we have the general form as y=mx+b
where m and b are constants.
We have to find the x intercept of the given function.
Given equation is [tex]x^{4} +x^{3} -4x^{2} -4x[/tex]
put this equation equals to 0
x^{4} +x^{3} -4x^{2} -4x = 0
[tex]x(x^{3} +x^{2} -4x-4)=0[/tex]
from this x = 0
x =1 is also the root of the equation
we get [tex]x^{2} -4=0[/tex]
from this
x = -2, 2
The intercept are 0,1,2,-2.

The value of m such that x +4 is a factor of 5x³ + 18x² + mx + 16 is; -4.
What is the value of m for which x +4 is a factor of 5x³ + 18x² + mx + 16?It follows from the task content that the value of m for which x +4 is a factor of 5x³ + 18x² + mx + 16 is to be determined.
Hence, if x + 4 is a factor, it follows that x = -4 is a zero of the expression.
Therefore; 5(-4)³ + 18(-4)² + m(-4) + 16 = 0.
-320 + 288 - 4m + 16 = 0.

A brief definition of a triangle according to Euclidean geometry is shown below:
Closed figure consisting in three non-colinear, all of them coplanar, points named vertices and three line segments associated to each pair of points named sides.
What is a triangle?
To understand what a triangle is, we need to understand some basic concepts of the Euclidean geometry. There are three undefined terms, that is, fundamental elements that cannot be defined but are described in terms of its attributes. Those terms are point, line and plane. The atributes of each element are described below:
Point - Location, discrete, no dimensions. Line - Continuous, length, no width. Plane - Length, width, no depth.A line can be formed by knowing the location of two distinct points on a plane. Lines can be continuous lines (endless), line segments (lines with finite length) or semirrays (lines with only one endpoint).
Let suppose that we have three points not collinear to each other, then we construct line segments for each pair of collinear points. Then, we create a triangle, whose brief definition is shown below:

1. Find the quotient of the averages prices of gold in 2010 and 1970. What
does the quotient mean?
Answer:
35.224137931
Step-by-step explanation:
2010: 1266.66
1970: 35.96
1266.66/35.96=35.224137931
Without the actual data for the average prices of gold in 2010 and 1970, I cannot provide the exact quotient. However, if we assume that we have the data, we can calculate the quotient by dividing the average price of gold in 2010 by the average price of gold in 1970. The resulting quotient would indicate how many times more expensive gold was in 2010 compared to 1970.
For example, if the average price of gold in 2010 was $1,500 per ounce and the average price in 1970 was $35 per ounce, then the quotient would be:
$1,500 / $35 = 42.86
This means that the average price of gold in 2010 was 42.86 times more expensive than the average price in 1970.
It is important to note that the actual quotient will depend on the actual data for the average prices of gold in 2010 and 1970.

What is inequality ?
inequality, When two numbers or algebraic expressions are stated to be greater than, greater than or equal to, less than, or less than or equal to each other in order. Inequalities can be stated as either statements of fact in the form of theorems, which are solved using methods similar to those used to solve equations, or as questions. For instance, the triangle inequality states that the length of the remaining side is greater than or equal to the sum of the lengths of any two sides of a triangle. Many of these inequalities, including the Cauchy-Schwarz inequality, are used in the proofs of many of mathematical analysis' most significant theorems.

The quotient of 550six and 50six is obtained by the calculation to be 11 six
What is the quotient?We know that the result that we obtain after we have carried out a division operation is called a quotient. In this case, we have been required to carry out the operation of division in base six.
We could start by converting the both values to base 10 as follows;
(5 * 6^2) + (5 * 6^1) + (0 * 6^0) = 180 + 30 + 0 = 210 ten
(5 * 6^1) + (0 * 6^0) = 30 + 0 = 30 ten
Then we carry out the division in base ten; 210 ten/30 ten = 7 ten

32 quarts make up one bushel, which is a unit of dry volume.
1 bushel = 32 quarts
11 bushels = (32 × 11) quarts = 352 quarts

A peck, which equals 16 dry pints in imperial and American usage, is a unit of dry volume.
1 peck = 16 pints
3 pecks = 3 × 16 = 48 pints
c. 97 quarts to bushels
As we know, 1 bushel = 32 quarts
1 quart = 1/32 bushel
97 quarts = 97/32 ≅ 3.03 bushels
d. 1,120 quarts to pecks
A peck is an imperial and American customary dry volume measurement unit that is equal to 8 dry quarts.

How to illustrate the information?There are many other types of reactions in chemistry, but the exothermic reaction and the endothermic reaction are the two most common forms.
Respiratory reaction is an example of an exothermic reaction, which is one in which energy is released in the form of heat. Exothermic reactions transfer energy from the system to the environment, raising the ambient temperature.
An endothermic reaction is one in which energy is removed from the system during the process. An example of an endothermic reaction is photosynthesis, in which plants use solar energy to produce food.
Therefore, a chemical reaction is said to be exothermic when it releases energy and causes a change in the environment's temperature.

1. Use complete sentences to explain how the special angles created by the Intersection of A and B by D can beused to solve for x.2. Solve for x, showing all of your work.3. Find the measure of <6.
According to the graph we have:
1. If the lines A and B cut by the secant D are parallel, then the collateral angles are supplementary, i.e. add up to 180°. In this case:
[tex](3x+7)+(4x+5)=180[/tex]2. Solve for x:
[tex]\begin{gathered} 3x+7+4x+5=180 \\ 7x+12=180 \\ 7x+12-12=180-12 \\ 7x=168 \\ \frac{7x}{7}=\frac{168}{7} \\ x=24 \end{gathered}[/tex]Answer: x = 24
3. Angle 6 corresponds to angle 3x + 7 so they are equal. So:
[tex]\angle6=3x+7[/tex]Where: x = 24
Substitute the value:
[tex]\angle6=3(24)+7=72+7=79[/tex]Answer: <6 = 79°

What is coordinate plane ?A coordinate plane is a two-dimensional surface made up of two number lines. It is produced when a horizontal line crosses the origin, which is the location where the X- and Y-axes meet. The numbers on a coordinate grid are used to find points. Using a coordinate plane, you may graph points, lines, and many other things. It functions as a map and gives precise driving instructions between two locations. The definition of a coordinate plane is as follows: A coordinate plane, also known as a rectangular coordinate plane grid, is made when the X-axis and Y-axis, two horizontal lines, cross.
Given that :P(0,0) , Q(-2,1) , R(3,3)

The cost in dollars of making x items is given by ()=10+500. The fixed cost is
determined when zero items are produced. Find the fixed cost for this item. What
is the cost of making 25 items? Suppose the maximum cost allowed is $1500.
What are the domain and range of the cost function, C(x) ?
The answer is
(a) the fixed cost when zero items are produced is $500 .
(b) cost for making 25 items is $750 .
(c) the domain and range of cost function is [0,100] and [500,1500] respectively .
It the question ,
it is given that
the cost function is C(x)=10x+500
Part(a)
to determine the fixed cost when 0 items are produced
Since 0 items are produced , we substitute the value x=0 in the cost function , we get
C(0)=10(0)+500
= 500
the fixed cost is $500.
Part(b)
to find the cost of making 25 items , we substitute x=25
On substituting the x=25 , we get
C(25)=10(25)+500
= 250+500
=750
the cost for 25 items is $750.
Part(c)
to find the domain of the cost function C(x)
Given that the maximum cost allowed is 1500
So, 1500=10x+500
10x=1500-500
10x=1000
x=100
So minimum 0 items and maximum 100 items can be produced ,
hence the Domain is [0,100]
to find the range
substituting x=0, the cost = $500
on substituting x=100 , the cost = $1500
the Range is [500,1500]
Therefore , (a) the fixed cost when zero items are produced is $500 .
(b) cost for making 25 items is $750 .
(c) the domain and range of cost function is [0,100] and [500,1500] respectively .
The given question is incomplete , the complete question is
The cost in dollars of making x items is given by C(x)=10x+500. The fixed cost is determined when zero items are produced.
(a) Find the fixed cost for this item.
(b) What is the cost of making 25 items?
