Construct a polynomial function with the following properties: third degree, 2 is a zero of multiplicity 1, −4 is the only other zero, leading coefficient is 2.
The polynomial in standard form is equal to 2 · x³ + 12 · x² - 64.
How to derive a cubic equation
Cubic equations have three roots. In this problem we need to derive a cubic equations whose three real roots (r₁, r₂, r₃) and leading coefficient (a) are given. The procedure consists in substituting on factor form of a cubic polynomial and expanding the resulting expression until standard form is obtained.
First, substitute on the factor form of the cubic equation:
y = 2 · (x - 2) · (x + 4)²
Second, expand the polynomial until its standard form is found:
y = 2 · (x - 2) · (x² + 8 · x + 16)
y = 2 · (x³ + 8 · x² + 16 · x - 2 · x² - 16 · x - 32)
y = 2 · (x³ + 6 · x² - 32)
y = 2 · x³ + 12 · x² - 64
The polynomial is equivalent to 2 · x³ + 12 · x² - 64.

What is the difference between communism and capitalism
Answers
The primary difference explained in capitalism vs communism is that capitalism is an economic system that allows private ownership and promotes the idea of a free market; in contrast, communism favours collective ownership and restricts the free market with government intervention portraying a planned economy.
Explanation
What is Capitalism?
Capitalism occurs when people are allowed to own and control capital assets, use them according to their self-interest, and earn profit by producing valued goods and services utilizing capital resources. In a capitalist economy, government intervention will be minimal; hence, the production of goods and services is driven by supply and demand. It creates an environment that promotes individualism, innovations, competition, efficient allocation of resources, the efficiency of the private sector, presenting consumers with better choices, and improving living standards. capitalism vs communism.
On the other hand, capitalism is often blamed for favouring the rich. The opponents of the system advocate that in capitalism, the rich get richer and the poor get poorer instigating the unequal distribution of wealth and inequality, creating social division. Moreover, in the wake of producing profit, the capitalist model exploits the workers, and unfair competition can also lead to the emergence of monopolies in specific sections. All these disadvantages communicate the need for the reformation of capitalism.
What is Communism?
Communism ideology aims to establish common ownership and eliminate the private property concept. It simply focuses on replacing private ownership and introducing state-owned organizations, projects, resources, and properties, ensuring economic equality and fairness. Such economies work towards achieving social development, welfare, and the overall development of all the citizens of a nation.
China has long been a significant example of a communist government where the government-controlled major resources, funds, products, and services, but later due to globalization and certain other aspects, has started implementing some elements of capitalism to grow business and take advantage of trade opportunities. Similarly, it has been observed that many nations turn their heads toward capitalism to obtain more opportunities, attain industrialization, and reap the benefits of globalization hence strengthening the capitalism vs communism debate.
Capitalism and communism are inherently contrasting concepts. While capitalism propagates individualism, communism is associated with collectivism. Industrial capitalism was popularised in the 18th century, and modern communism was propagated in the 19th century.
The instances reflecting the conflict based on these ideologies were prevalent from the old times. For example, ideological conflict, and capitalism vs. communism in the Cold War of the 20th century. During the Cold War, the United States and Western European nations were based on capitalism and democracy. In contrast, the Soviet Union was based on communism and dictatorship, and Eastern European nations were under Soviet communist control. Many of the significant events in the Cold War contributed to explaining whether capitalism was better than communism or not.

if after 40 month amount of 2375 is received by 15/2% interest rate, how much is principal ?
The principal is 1900
From the question, we have
after 40 month amount of 2375 is received by 15/2% interest rate
T = 40/12 = 10/3
amount = 2375 = P+I
R = 15/2%
amount = P+I
2375 = P+(PRT)/100
2375 = P(1+(RT)/100)
substituting the value we get
2375 = P(1+(25)/100)
2375 = P*125/100
P = 2375*100/125
P = 1900
Multiplication:
Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious. In mathematics, the repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.

Step-by-step explanation:
Domain is the x value and Range is the y value. (A way to remember is by saying dr since domain is x and range is y)
Y value is also called f(x) as shown on your screen
The points are
(1,-8)
(2,5)
(3,-2)
(4,1)
The domain would be 4,3,2,1 and the range would be -8,-2,1,5
The common difference is that the domain follows a constant change of rate, but not the range.
A constant change of rate means that it's changing at a constant rate.
It can also be called slope.
E.G: 1,2,3,4 (constant change of rate is adding 1) or 9,6,3,0 (subtracting 3)
The domain is subtracting 1, yet the range isn't following a constant change of rate.
A way to find slope is in the image.
(1,y) and (x,−3).
6x+3y=15
The values of x and y are 4 and 3 respectively, this forms an ordered pair of (1,3) and (4,-3).
What are the the values of x and y?Given the equation and ordered pair the question;
6x + 3y = 15Point: ( 1,y)Point; (x,−3).To determine, the y-value, plug the x-value into the equation and solve for y.
6x + 3y = 15
Plug in x = 1
6(1) + 3y = 15
6 + 3y = 15
3y = 15 - 6
3y = 9
y = 9/3
y = 3
To determine, the x-value, plug the y-value into the equation and solve for x.
6x + 3y = 15
Plug in y = -3
6x + 3( -3 ) = 15
6x - 9 = 15
6x = 15 + 9
6x = 24
x = 24/6
x = 4
Therefore, the ordered pair are (1,3) and (4,−3).

4. Determine if the table represents a
linear or nonlinear function.
Answer:
1st Table : Linear
2nd Table : Non-Linear
Step-by-step explanation:
To determine if the function is Linear or not , we find the change in y with a certain change in x
So for the 1st Table:
When x changes from x = 2 to x = 4 increased by 2
Then y changes from y = 3 to y = 0 decreases by 3
When x changes from x = 4 to x = 6 increased by 2
Then y changes from y = 0 to y = -3 decreases by 3
Since change in y is the same for the same change in x , Then the Function is Linear
So for the 2nd Table:
When x changes from x = 1 to x = 2 increased by 1
Then y changes from y = 1 to y = 4 increased by 3
When x changes from x = 2 to x = 3 increased by 1
Then y changes from y = 4 to y = 9 increased by 5
Since change in y is not the same for the same change in x , Then the Function is Non-Linear

Micheal wants to buy an efficient smart car that according to the latest EPA standards gets 33 mpg in the city and 40 mpg on the highway. The car that Micheal picked out costs $16,100. His dad agreed to purchase the car if Michael would pay it off in equal monthly payments for the next 70 months. The equation y= -230x+16,100 represents the amount, Y (in dollars), that Michael owes his father after X months.
A) How much does Michael owe his dad after six months?
B) determine the slope of the line and interpret its meaning in the context of this problem.
1) Micheal owes his father $[ ] after 6 months.
2) The slope is [ ]
3) The amount Michael owes his father [choose one] by $[ ] per month.
$17690 is the amount Michael owed his dad .
What is linear equation ?Equations and equations of maximum degree 1 are also called "linear equations". The linear equation formula can be written as Y = mx + b. where m is the slope of the line, b is the y-intercept, and x and y are the variables. Slope indicates the direction and slope of the line. . This is because (0,y) is the point where the line intersects the y-axis.
CalculationThe amount Michael owes is given by :
y = - 290x +18,560
x = number of months ; y = amount owed
Amount owed after 3 months :
Put x = 3 in the equation :
y= - 290(3) +18,560
y = - 870 + 18560
y = 17690
According to the general form of a linear equation :
y = mx + c
Where, m = slope ; c = intercept
The slope = - 290 ; Intercept = 18560
Slope is the change in y per unit change in x ; The slope means that amount owed, y decreases by 290 per month
The intercept shows that the original amount borrowed is 18560
Amount Michael owes his father decreases by 290 per month.

Solve: √2x-9 = x-6
a) x=9
b) The equation has no solution.
c) x= 5,9
d) x=5
Answer:
A
Step-by-step explanation:
STEP 1:
Isolate the square root on the left hand side
Radical already isolated
√2x-9 = x-6
STEP 2:
Eliminate the radical on the left hand side
Raise both sides to the second power
(√2x-9)2 = (x-6)2
After squaring
2x-9 = x2-12x+36
STEP 3:
Solve the quadratic equation
Rearranged equation
x2 - 14x + 45 = 0
This equation has two rational roots:
{x1, x2}={9, 5}
STEP 4:
Check that the first solution is correct
Original equation
√2x-9 = x-6
Plug in 9 for x
√2•(9)-9 = (9)-6
Simplify
√9 = 3
Solution checks !!
Solution is:
x = 9
STEP 5:
Check that the second solution is correct
Original equation
√2x-9 = x-6
Plug in 5 for x
√2•(5)-9 = (5)-6
Simplify
√1 = -1
Solution does not check
1 ≠ -1
One solution was found :
x=9
Hope this helps!!
