A polynomial is an expression consisting of variables and coefficients and factoring is the process of breaking down a polynomial into simpler units
A polynomial is an expression consisting of variables and coefficients, which are combined using only addition, subtraction, and multiplication. For example, 3x^2 + 2x - 1 is a polynomial, where x is the variable, 3 and 2 are coefficients, and ^2 and ^1 are exponents.
Factoring is the process of breaking down a polynomial into simpler units, which can be multiplied together to obtain the original polynomial. The simplest units are usually linear expressions, which have the form ax + b, where a and b are coefficients. For example, the polynomial 3x^2 + 2x - 1 can be factored into (3x - 1)(x + 1) by identifying two linear expressions that when multiplied together produce the original polynomial.
Factoring is an important tool in algebra, as it can help to simplify expressions, solve equations, and identify the roots of a polynomial.

If the angles of a triangle are in the ration of 3 : 4 : 5, find them.
Answer:
the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.
Step-by-step explanation:
Let's denote the angles of the triangle as 3x, 4x, and 5x, where x is a constant.
Since the sum of the angles of a triangle is 180 degrees, we can write the following equation:
3x + 4x + 5x = 180
Simplifying this equation, we get:
12x = 180
Dividing both sides by 12, we get:
x = 15
Therefore, the angles of the triangle are:
3x = 3(15) = 45 degrees
4x = 4(15) = 60 degrees
5x = 5(15) = 75 degrees
So the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.

A double ferris wheel is pictured below. A large rotating arm with diameter 20 is centered 14 meters off the ground, and completes one rotation every 11 minutes. At the end of each side of the large arm is a smaller wheel with diameter 6 meters, which completes one rotation about its center every 6 minutes.
If you board the ferris wheel at point P at time t = 0, and each wheel rotates in the direction shown by the arrows, find an equation for your height, H above ground after t minutes.
This equation reflects the passenger's height above the ground after t minutes: H = 14 + 3 + (10)sin(2πt/11) + (3)sin(2πt/6).
What is equation?An equation in mathematics is a statement that two mathematical expressions are equal. Equations are used to represent mathematical relationships and to describe the behavior of systems or processes. An equation typically consists of two sides, separated by an equal sign (=). On one side of the equal sign is the expression representing what is known or given, and on the other side is the expression representing what is being found or sought. Equations can be used to model real-world situations, to describe the behavior of mathematical functions, to solve problems, and to make predictions. They are an important tool in many areas of mathematics and science, including algebra, calculus, physics, and engineering.
Here,
The height of a passenger on a double Ferris wheel can be calculated by considering the combined effect of two rotations: the rotation of the large arm and the rotation of the smaller wheel.
Let's call the length of the small arm as x, which is equal to half of the diameter of the small wheel, i.e. x = 3.
At time t = 0, the passenger is at point P, which is x meters above the ground. As the large arm rotates, the height of the passenger will change according to the formula:
H = 14 + x + (20/2)sin(2πt/11)
Where H is the height above the ground after t minutes, and (20/2) is half of the diameter of the large arm.
Additionally, as the small wheel rotates, the height of the passenger will change according to the formula:
H = H + (3)sin(2πt/6)
So, combining both the effects, the height of the passenger on the Ferris wheel can be expressed as:
H = 14 + 3 + (10)sin(2πt/11) + (3)sin(2πt/6)
This equation represents the height of the passenger above the ground after t minutes: H = 14 + 3 + (10)sin(2πt/11) + (3)sin(2πt/6).

The table shows the number of pounds, x, of coffee ordered and the total price, y, in dollars, of each order. X 5 6 7 10 y $35 $42 $49 $70 Which best represents the units for the rate of change (rise over run) in the table? a.dollars. b.dollars per pound. c.pounds b.pounds per dollar
To find the units for the rate of change (rise over run), we need to determine the change in y (rise) divided by the change in x (run) for any two points in the table.
Let's choose the first and last points in the table, (5, $35) and (10, $70), respectively. The change in y is $70 - $35 = $35, and the change in x is 10 - 5 = 5. So the rate of change (rise over run) is:
rise/run = $35/5 = $7
Therefore, the best representation for the units of the rate of change is dollars per pound, as the rate of change indicates how much the price changes for every pound of coffee ordered. So the answer is (b) dollars per pound.

Javier is standing at a distance from a flagpole. He sights the bottom of the flagpole at a 4°
angle of depression and the top of the flagpole at a 25°
angle of elevation. If Javier is 6 feet tall, what is the total height, to the nearest foot, of the flagpole?
Answer: To find the height of the flagpole, we can use the fact that the angles of depression and elevation are complementary angles, meaning that they add up to 90°.
Let's call the height of the flagpole "h". Then, we have:
h - 6 = h * tan(4°) (the height difference between Javier and the bottom of the flagpole)
and
h = 6 + h * tan(25°) (the height of the top of the flagpole as seen by Javier).
By substituting the first equation into the second, we can find h:
h = 6 + h * tan(25°)
h = 6 + h / tan(65°)
h * tan(65°) = 6 + h
h * tan(65°) - h = 6
h = 6 / (tan(65°) - 1)
Using a calculator, we find that h = approximately 43.3 feet. Rounding to the nearest foot, the height of the flagpole is 43 feet.

Step-by-step explanation:
The histogram shows the ages of cars sold at a car auction. What percent of the cars was less than 20 years old or more than 40 years old?.
By the analysis of histogram , 40% percent of the cars was less than 20 years old or more than 40 years old.
The histogram may be seen here. Each column lists the age range at the bottom and the number of automobiles in that age group on the left.
The number of vehicles in the first two columns from the left (age 0-9 and 10-19) and the last two columns (age > 40) must be added together to determine the percentage of vehicles with less than 20 years or more than 40 years of age (age 40-49 and 50-59).
The total number of requested vehicles is equal to 8 that is (3 + 2 + 0 + 3).
The total number of automobiles must now be determined (by adding the cars in each column): 3 + 2 + 8 + 4 + 0 + 3 = 20
The ratio of the number of automobiles of the specified age to the total number of cars must then be calculated and converted into a percentage.
[tex]\frac{8}{20}[/tex][tex]= 0.40 = 40%[/tex]
40% percent of the cars was less than 20 years old or more than 40 years old.

If 0° ≤ Θ≤ 360°, then find angle(s) Θ.
1) csc Θ = undefined
Answer:
that these angles are inclusive of 0° and 360° because the question states that 0° ≤ Θ ≤ 360°.
Step-by-step explanation:
If csc Θ is undefined, that means that the sine of the angle is zero, because csc Θ is the reciprocal of the sine function, and division by zero is undefined.
So we need to find all the angles where sin Θ = 0.
The sine function is equal to zero at multiples of 180 degrees, so the solutions to sin Θ = 0 are:
Θ = 0°, 180°, 360°
Note that these angles are inclusive of 0° and 360° because the question states that 0° ≤ Θ ≤ 360°.

let a (x)=3x^3-4x^2+x, and b(x)=x^2+2
Divide polynomials with remainders
a(x) = b(x) * (3x² - 10x + 21) + (8x - 8)
Polynomial Division with RemaindersTo divide the polynomial a(x) by b(x), we can use long division as follows:
3x - 6
-------------------
x² + 2 | 3x² - 4x² + x
- (3x³ + 0x²)
---------------
-4x² + x
- (-4x² - 8)
-------------
8x - 8
Therefore, the quotient is 3x - 6, and the remainder is 8x - 8.
We can write the result of the division as:a(x) = b(x) * (3x - 6) + (8x - 8)
Alternatively, we can use synthetic division to get the same result:-2 | 3 -4 1 0
| -6 20 -42
|-------------
| 3 -10 21 -42
The numbers on the bottom row represent the coefficients of the quotient, which are 3, -10, 21. The last number on the bottom row, -42, is the remainder. Therefore, the quotient is:
3x² - 10x + 21
And the remainder is:8x - 8
We can write the same result as before:a(x) = b(x) * (3x² - 10x + 21) + (8x - 8)

Week 1 Demand: 50 Forecast: 49
Week 2 Demand: 54 Forecast: 56
Week 3 Demand: 58 Forecast: 60
The Tracking Signal in Week 3 is -1.8.
The Tracking Signal in Week 3 can be calculated by using the following formula:
Tracking Signal = (Sum of Forecast Errors) / (Mean Absolute Deviation)
First, we need to calculate the forecast errors for each week:
Week 1 Forecast Error = Actual Demand - Forecast = 50 - 49 = 1
Week 2 Forecast Error = Actual Demand - Forecast = 54 - 56 = -2
Week 3 Forecast Error = Actual Demand - Forecast = 58 - 60 = -2
Next, we need to calculate the Mean Absolute Deviation (MAD):
MAD = (|1| + |-2| + |-2|) / 3 = (1 + 2 + 2) / 3 = 5 / 3 = 1.67
Finally, we can calculate the Tracking Signal:

Marcus is 30 years younger than his mother. In 5 years, Marcus' age will be 1/4 of his mother's age. Find Marcus' mother's current age
Marcus is 30 years younger than his mother. Marcus' mother's current age is 35 years old.
To find Marcus' mother's current age, we need to use a system of equations.
Let:
x = Marcus' current age
y = his mother's current age.
We can write two equations based on the information given:
x = y - 30 (Marcus is 30 years younger than his mother)
x + 5 = 1/4(y + 5) (In 5 years, Marcus' age will be 1/4 of his mother's age)
Now we can substitute the first equation into the second equation and solve for y:
y - 30 + 5 = 1/4(y + 5)
y - 25 = 1/4y + 5/4
(3/4) y = 105/4
y = 105/3 = 35

What is meant by slope-intercept form of the line equation?
The slope (m) and the y-intercept (b) of a line are highlighted in the slope-intercept form of linear equations (y=mx+b). One of the most popular ways to represent a line's equation is in the slope-intercept form of a straight line. When the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis) are known, the slope-intercept formula can be used to determine the equation of a line. The equation of a line is the equation that each point on the line fulfils.
Given the line passes through the points (– 8,9) and ( – 2, – 9).
When only two points on the line are given, the equation of the line is:
y - y₁ = m ( x - x₁)
m = slope = [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex] = (-9 - 9)/ ( -2 -(-8)) = -18/ 6 = -3
