The factored form of the polynomial is (5x^(3))(-x^(3)+3x+4).
To factor the polynomial with a negative coefficient, -5x^(6)+15x^(4)+20x^(3), we can use the content loaded factor method. This method involves factoring out the greatest common factor (GCF) of all the terms in the polynomial.
The GCF of -5x^(6), 15x^(4), and 20x^(3) is 5x^(3). So, we can factor out 5x^(3) from each term:
-5x^(6) = -(5x^(3))(x^(3))
15x^(4) = (5x^(3))(3x)
20x^(3) = (5x^(3))(4)
Now, we can rewrite the polynomial as:
-5x^(6)+15x^(4)+20x^(3) = (5x^(3))(-x^(3)+3x+4)
So, the factored form of the polynomial is (5x^(3))(-x^(3)+3x+4).
In summary, the polynomial -5x^(6)+15x^(4)+20x^(3) can be factored as (5x^(3))(-x^(3)+3x+4) using the content loaded factor method.

The answer to the equation cos195°cos285° is -1/4.
What is equation?An equation is a mathematical statement that asserts the equality of two expressions. Equations are used to describe relationships between different quantities and can be used to solve for unknown values. Equations are typically written as symbols, but can also be written in words. Simple equations might involve addition, subtraction, multiplication, and division, while more complex equations may involve exponents, logarithms, and trigonometric functions. Equations can be used to model and understand real-world phenomena, such as calculating projectile motion, or predicting the behavior of a chemical reaction.
This is derived from the trigonometric identity cos{60°−x}cosx – sin(60°−x)sinx. This identity states that the cosine of the sum of two angles is equal to the product of the cosines of each angle minus the product of the sines of each angle.
By substituting the angles 195° and 285° into the identity, we get cos{60°−195°}cos195° – sin(60°−195°)sinx. When we use the values of the angles, we get cos{-135°}cos195° – sin(135°)sinx. We can then simplify this to -1/4cos195° – 0sinx. As the sine of the angle is 0, this simplifies to –1/4cos195°. As the cosine of 195° is -1/4, the answer to the equation cos195°cos285° is -1/4.

Unit 3 Test Review Name Raver mial Functions Express (3x^(3)-2x^(2)+3)/(x-1) in the form q(x)+(r(x))/(b(x))
The given function is (3x^(3)-2x^(2)+3)/(x-1). To express it in the form q(x)+(r(x))/(b(x)), we need to use polynomial long division.
First, divide the first term of the numerator, 3x^(3), by the first term of the denominator, x:
3x^(3)/x = 3x^(2)
Now, multiply this result by the denominator and subtract it from the numerator:
(3x^(3)-2x^(2)+3) - (3x^(2)(x-1)) = -2x^(2)+3x^(2)-3
Simplify:
x^(2)-3
Next, divide the first term of the new numerator, x^(2), by the first term of the denominator, x:
x^(2)/x = x
Multiply this result by the denominator and subtract it from the new numerator:
(x^(2)-3) - (x(x-1)) = -3+x
Simplify:
x-3
Since the degree of the new numerator is less than the degree of the denominator, we can stop here. The final result is:
q(x) = 3x^(2)+x
r(x) = x-3
b(x) = x-1
So, the function can be expressed as:
(3x^(3)-2x^(2)+3)/(x-1) = 3x^(2)+x + (x-3)/(x-1)
In HTML format, the answer would be:
<p>(3x^(3)-2x^(2)+3)/(x-1) = 3x^(2)+x + (x-3)/(x-1)</p>

Writing the equation of a functionFrom the question, we are to determine the equation for the function
From the the given table,
When x = 0, y = 2
and when x = 1, y = 6
We can determine the equation for the function by using the formula,
(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)
From above
x₁ = 0

What is system of linear equations?
A system of linear equations is a set of two or more equations with two or more variables that are to be solved simultaneously. Each equation in the system is linear, meaning it can be written in the form of ax + by + cz + ... = d, where a, b, c, and d are constants and x, y, z, and other variables are unknowns.
The goal of solving a system of linear equations is to find the values of the variables that satisfy all of the equations in the system. The solution of a system of linear equations is a set of values for the variables that make all of the equations true.
There are different methods to solve systems of linear equations, such as substitution method, elimination method, and matrix method. These methods involve manipulating the equations in the system to isolate one variable, substitute its value into another equation, and eventually find the values of all the variables.
Systems of linear equations are used in many areas of mathematics, science, engineering, and economics to model real-world situations and solve practical problems.
To find the solution to the set of equations, we need to determine the values of x and y that satisfy both equations simultaneously. One way to do this is to use substitution or elimination methods.
However, the given answer choices do not seem to be the steps of a solution process. We need to use both equations to find a solution. Here is one possible way to do it:
Equation S: y = x + 9
Equation T: y = 2x + 1
Since both equations equal to y, we can set them equal to each other:
x + 9 = 2x + 1
Simplifying this equation, we get:
x = 8
Now that we know the value of x, we can substitute it into either Equation S or Equation T to find the value of y. Let's use Equation S:
y = x + 9
y = 8 + 9
y = 17
Therefore, the solution to the set of equations is (x, y) = (8, 17).
None of the given answer choices matches this solution process.

The x-intercepts of R(x) are (-3,0), (1,0), and (-2,0), and the y-intercept is (0,-24).
To find the x-intercepts of R(x) = (2x+6)(x-1)(4-2)(x+2), we need to set R(x) equal to 0 and solve for x:
0 = (2x+6)(x-1)(4-2)(x+2)
This equation can be simplified to:
0 = (2x+6)(x-1)(2)(x+2)
We can use the zero product property to find the x-intercepts:
2x+6 = 0, x-1 = 0, 2 = 0, x+2 = 0
Solving for x, we get:
x = -3, x = 1, x = -2
So, the x-intercepts are (-3,0), (1,0), and (-2,0).
To find the y-intercepts, we need to set x equal to 0 and solve for R(x):
R(0) = (2(0)+6)(0-1)(4-2)(0+2)
R(0) = (6)(-1)(2)(2)
R(0) = -24

Answer: -sqrt(3)/4
Step-by-step explanation:
To solve this trigonometric expression, we can use the following trigonometric identities:
sin (180 + x) = -sin x
cos (180 + x) = -cos x
Using these identities, we can rewrite the expression as:
sin(200°)cos(80°) - cos(200°)sin(80°)
= sin(180° + 20°)cos(80°) - cos(180° + 20°)sin(80°)
= -sin(20°)cos(80°) + cos(20°)sin(80°)
= (cos(20°) - sin(20°))sin(80°)
= sin(70°)sin(80°)
= (cos(20°) - cos(150°))/2
= (-sqrt(3)/2 - sqrt(3)/2)/2
= -sqrt(3)/4
Therefore, sin(200°)cos(80°) - cos(200°)sin(80°) = -sqrt(3)/4.

∠ F = ∠ K = 90 degrees
∠ G = L = 90 degrees
∠ H = ∠ M = 115 degrees
How to find the scale factor25. The scale factor of JKLM and EFGH is calculated using corresponding sides
side EF * scale factor = side JK
8 * scale factor = 20
scale factor = 20 / 8
scale factor = 2.5
26. The congruent angles include
∠ E = ∠ J = 65 degrees
∠ F = ∠ K = 90 degrees
∠ G = L = 90 degrees
∠ H = ∠ M = 360 - 90 - 90 - 65 = 115 degrees
27. the ratios of the corresponding side lengths
JK / EF is proportional to KL / FG is proportional to LM / GH is proportional to MJ / EH
28. the values of x, y, and z
x = 2.5 * FG = 2.5 * 11 = 27.5
y = 30 / 2.5 = 12
z = 65 degrees
29. the perimeter of each polygon
the smaller polygon EFGH = 8 + 11 + 3 + 12 = 34
the bigger polygon JKLM = 20 + 27.5 + (3 * 2.5) + 30 = 85
30. the ratio of the perimeters of JKLM to EFGH
= 85 / 34 = 2.5
31. the area of each polygon
the smaller polygon EFGH = 0.5(3 + 8) * 11 = 60.5
the bigger polygon JKLM = 0.5(20 + 7.5) * 27.5 = 378.125
32. the ratio of the areas of JKLM to EFGH
= 378.125 / 60.5 = 6.25

Consider thatzis a real number, determine the value (s) forβsuch thatz=1+iββ+2iβ=±2β=±2β=±1β=±3None of the given options
The given equation is z = 1 + iβ/β + 2i. We need to determine the value(s) for β such that the equation holds true.
First, we can multiply both sides of the equation by β + 2i to get rid of the denominator:
z(β + 2i) = 1 + iβ
Next, we can distribute the z on the left-hand side of the equation:
zβ + 2iz = 1 + iβ
Now we can rearrange the equation to get all the β terms on one side:
zβ - iβ = 1 - 2iz
We can factor out the β on the left-hand side:
β(z - i) = 1 - 2iz
Finally, we can divide both sides of the equation by z - i to get the value of β:
β = (1 - 2iz)/(z - i)
This is the value of β that satisfies the given equation. None of the given options match this value, so the correct answer is "None of the given options."

In a certain investigation: 460 persons were involved in the study: and based on an enquiry on their age. it was known that 75% of them were 22 or more years. The following frequency distribution shows the age composition of the persons under study. Find the mean and modal life of condensers_ Mid; age in years No. of persons 18 f; 23 28 33 90 122 ; 38 56 48 24 20 33'
Therefore , the solution of the given problem of percentage comes out to be 38 years old is the median age.
What does a percentage actually mean?In statistics, a "a%" is a figure or statistic that is expressed as a percentage of 100. The words "pct," "pct," but instead "pc" are also not frequently used. However, the sign "%" is frequently used to represent it. The percentage sum is flat; there are no dimensions. Percentages are truly integers because their numerator almost always equals 100. Either the % symbol (%) or the additional term "fraction" must come before a number to denote that it is a percentage.
Here,
The following algorithm must be used to determine the mean age:
=> mean = (all years added together) / (total number of persons)
The representative age for each age group is the age that falls in the middle of the range. With this approach, we can determine the total age as follows:
=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)
=> 162 + 644 + 924 + 2970 + 4636 + 2688 + 1152 + 1520 + 272.25
=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)
According to the information provided, there are 460 people in total.
=> mean = 17745.25 / 460
=> mean = 17745.25 / 460
As a result, the average lifespan is roughly 38.552 years.
The age category in this instance with the highest frequency has a midpoint of 38 and a frequency of 122. As a result, 38 years old is the median age.
