help please 50 points Tia and Marcus are having a debate about the graph below. Tia says that this is an x^5 function while Marcus claims that it is an x^4 function. Find the fully factored form of this equation and determine who is correct in the debate. You can use the end behavior chart to help you explain your reasoning.
Answer:
[tex]f(x) = \dfrac14(x + 1)^2(x + 3)(x -2)( x - 3)[/tex]
Tia is correct
Step-by-step explanation:
From inspection of the graph, we can say that the leading coefficient of the function is positive as:
[tex]f(x) \rightarrow - \infty, \textsf { as } \ x \rightarrow - \infty\\f(x) \rightarrow +\infty, \textsf { as } \ x \rightarrow + \infty[/tex]
From inspection of the graph, we can see that the curve intercepts the x-axis at x = -3, x = 2, x = 3
As the curve touches the x-axis at (-1, 0) then this means that the root x = -1 has multiplicity 2
Therefore, [tex]f(x) = a(x + 1)^2(x + 3)(x -2)( x - 3)[/tex] where [tex]a[/tex] is some positive constant.
If we multiply the constants, we can determine the y-intercept:
y-intercept = a x 1² x 3 x -2 x -3 = 18a
Therefore, the y-intercept is at y = 18a
From inspection of the graph, the y-intercept is at y = 4.5
So to determine the value of a: 18a = 4.5 ⇒ a = 1/4
Therefore, the fully factored form of the equation is:
[tex]f(x) = \dfrac14(x + 1)^2(x + 3)(x -2)( x - 3)[/tex]
A decision maker wants to incorporate geographic region into a multiple regression model, where the possible responses are: north, south, east, and west. How many dummy variables will be added to the model
The decision-maker is advised to use three dummy variables. The rule of thumb states that it is better to use lesser dummy variables than the categories being investigated. In this case, the categories are four - North, South, East, and West.
What is a Dummy Variable?This is a statistical term that refers to a factor that is characterized with the value of one or zero in order to explain the presence of absence of an effect that is categorized.
This is used mainly in regression analysis.

[tex]\huge\boxed{(12,80),(10,65)}[/tex]
Step-by-step explanation:
The line given has a slope of 7.5 and a point at (12, 80)
Because of the slope, simply subtract 2 from the x and subtract 15 from the y to get another point, at (10, 65)
Thus, simply put your points at (10, 65) and (12, 80)

Based on the diagram below, what is the interior measure of ∠Y ?
Answer:
∠Y = 104°
Step-by-step explanation:
vertical angles are equal ⇒ ∠DAN = ∠SAY = 48°
Sum of interior angles of a triangle = 180°
⇒ ∠SYA + 56 + 48 = 180
⇒ ∠SYA = 76°
Angles on a straight line add up to 180°
⇒ ∠Y + ∠SYA = 180°
⇒ ∠Y + 76 = 180
⇒ ∠Y = 104°

Help please! I need the area of this given figure. The formula is A=1/2(b1+b2)h
Answer:
324 square feet (or whatever you call it i don't use feet and inches lol)
Step-by-step explanation:
We gotta divide this into a trapezoid and a rectangle.
the rectangle part is easy which is 6x18=108
Then the trapezoid
b1=6 b2=18 h=18
6+18=24
24x18=432
432/2=216
now we add them 216+108=324

Kay's gross pay is $2,851. Her deductions total $491.22. What percent of her gross pay is take-home pay?
Show work for 80 points!!!!
Answer:
Her take home pay is $2359.78
The percentage is approximately 82.77%
Step-by-step explanation:
Gross is the full before tax or whatever.
$2851 - $491.22 = $2359.78
$2359.78 / $2851 = 0.827702
$2851 - $491.22 = $2359.78
$2359.78 / $2851 = 0.827702
so the answer is 0.827702

The stock of Company A gained 4.25% today to $16.68. What was the opening price of the stock in the beginning of the day?
Answer:
16
Step-by-step explanation:
Let the opening price be x
So the amount of gained will be $16.68 - $x
Next, this value correspond to 4.25% of the opening price of the stock which is x
Thus,
[tex]4.25[/tex]% of [tex]x = 16.68 - x[/tex]
[tex]\frac{4.25}{100} * x = 16.68-x[/tex]
Cross multiply
[tex]4.25x = 100(16.68-x)[/tex]
[tex]4.25x = 1668 - 100x[/tex]
[tex]100x + 4.25x = 1668[/tex]
[tex]104.25x = 1668[/tex]
[tex]x = \frac{1668}{104.25}[/tex]
[tex]x = $16[/tex]
Check Answer:
$16 x 4.25%=.68
$16 + .68 = 16.68
Hence, x = 16 is correct

What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
So the percentage actually means a part per 100.
Percentage is usually denoted by the symbol '%'.
Given that,
The stock of Company A gained 4.25% today to $16.68.
We have to find the opening price of the stock in the beginning of the day.
Let the opening price be x.
x + 4.25% of x = 16.68
x + (4.25/100 x) = 16.68
x + 0.0425x = 16.68
1.0425x = 16.68
x = 16
Hence the opening price of the stock was $16.

In a US presidential election of the 227 million eligible voters, 51.5 percent voted in the election. Let A and B be the number of people who voted for candidates Alpha and Beta, respectively.
How many people voted in the election?
Assume all voters voted for candidate Alpha or candidate Beta. Write an equation for A in terms of B
Candidate Alpha won the popular vote by 4.8 million votes. Write an equation for A in terms of B
Assuming b. and c., how many people voted for candidate Beta?
Assuming b. and c., how many people voted for candidate Alpha?
Using a system of equations, it is found that:
117 million people voted in the election.The equation for A in terms of B is given by: A = 117 - B.61.1 million people voted for candidate B.65.9 million people voted for candidate A.What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are A and B.
51.5% of 227 million eligible voters voted, hence, considering millions as the unit measure:
A + B = 0.515 x 227
A + B = 117.
The equation for A in terms of B is given by: A = 117 - B.
Candidate A won the popular vote by 4.8 million votes, hence:
A = B + 4.8.
B + 4.8 = 117 - B
2B = 112.2
B = 61.1.
A = 61.1 + 4.8 = 65.9.
Then:
61.1 million people voted for candidate B.65.9 million people voted for candidate A.More can be learned about a system of equations at https://brainly.com/question/24342899
