Answer:
the graph is of a cubic function.
Step-by-step explanation:
f(x)= x^3. It should have at least one zero
The graph shows cubic polynomial.
What are Polynomial?A polynomial is an equation that solely uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are also known as indeterminates.
Given:
In the graph the number of times the graph touches the x- axis it will have that many zeroes or solution for the polynomial.
The given graph touches the x-axis three times which shows the polynomial will have three solution and the degree of the polynomial is 3.

An amusement park charges a $12 parking fee plus 25 per person. What is the total cost for 32 people?
Answer:
The total amount for 32 people is 15.36
Step-by-step explanation:
we know that for 25 people is $12 so we need to find how much it would be for one person. you would need to divide $12 / 25. from this you would get 0.48, so for one person it's 48 cents. next you're going to subtract 25 from 32, this leaves you with seven people who aren't in a group of 25. you then multiply 7 × this equals to 3.36, add 3.36 to $12 and you'll get your total 15.36.

The missing points are (7, 11), and (9, 9.8) and the type of correlation is negative.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
Let the line of best fit is:
y = mx + c
The missing points are:
(7, 11), and (9, 9.8)
The correlation will be negative.
The line of best fit is shown in the picture.
Thus, the missing points are (7, 11), and (9, 9.8) and the type of correlation is negative.

I don't understand this
Answer:
y=2/3x+3
Step-by-step explanation:
First, you would use the point slope formula : y₂-y₁/x₂-x₁
(5--3)/(3--9)
=8/12
=2/3
Then you would plug it back into the equation along with one of the points. Ex:
-3=2/3(-9)+b
-3=-6+b
3=b
So in conclusion, the formula would come out to y=2/3x+3

Answer:
76.3
Step-by-step explanation:
Answer:
C = 75°
Step-by-step explanation:
The interior angles of a triangle will always add up to 180°, so all we have to do is find the missing variable.
To do this, we first add up the two angles we do know.
—> 65 + 40 = 105
Now that we have the total of the other two angles, simply subtract 105 from 180.
—> 180 - 105 = 75
We now have our answer!

7. What number is 32% of 79?
A.n= 32.79: 2.528
B.32 = n. 79: 0.4
C.79=n.0.32: 246.9
D.n-0.32.79; 25.3
Answer:
If they're asking you to round, I'll choose D just because 25.28 is 25.3 rounded to the nearest tenth.
Step-by-step explanation:
79/x=100/32
(79/x)*x=(100/32)*x - we multiply both sides of the equation by x
79=3.125*x - we divide both sides of the equation by (3.125) to get x
79/3.125=x
25.28=x
x=25.28

Kailey correctly graphed the opposite of –3.3 on the number line.
A number line going from negative 5 to positive 5. Point A is between negative 4 and negative 3, point B is between negative 3 and negative 2, point C is at 3.3, and point D is at 3.9.
Which point could be the point Kailey graphed?
The number line shows that Kailey could have graphed the point C (3.3).
Number LineThe number line is the graphic representation of real numbers whose center is represented by the number zero (0). The negative numbers are on the left side of the number line, on the other hand, the positive numbers are written on the right side. See the attached image.
Opposite NumbersOpposite numbers are numbers that the distance to 0 is equal. The numbers are classified as the opposite when the sum between them is equal to zero (0).
STEP 1 - Plot the number linePlot the number line with the given limits: -5 to 5. See the attached image.
STEP 2 - Plot the given points in the number linePlot the points A, B,C an D in the number line drawn in step 1. See the attached image.
STEP 3 - Analyse the plotted number lineLike the point graphed is the opposite of -3.3, Kailey could have plotted the point C which is at 3.3 since the sum between -3.3 and 3.3 is equal to zero (0).
-3.3+3.3 =0

x²-4 / x²+9x+20 is greater than/equal to 0
Answer:
true
Step-by-step explanation:
x²-4/x²+9x+20 >=0
cross multiplying the equation we have,
(x²-4/x²+9x+20)*x²+9x+20 >= 0*x²+9x+20
= x²-4>=0
x²>=4
taking the square root of both sides, we have:
√x²>= √4

graph y = 4x-9 please
Step-by-step explanation:
Just take two random points, always remember ,take x=0 and find his correspondent y
in this case y=4*0-9=-9
first point (0,-9)
second one:
take any x you want, I took 2 randomly, and y will be
y=4*2-9=8-9=-1
second point is (2,-1)
find these points on graph and connect them with a ruler ! And that is the line you are searching for!
We want to graph the line y = 4*x - 9.
The graph can be seen at the end of the answer.
To graph a given linear function, we need to find two points that belong to the function, and then connect them with a line.
To find the points we just evaluate the function in two different values of x, so let's do that.
For x = 0 we have:
y = 4*0 - 9 = -9
Then we have the point (0, -9)
For x = 1 we have:
y = 4*1 - 9 = 4 - 9 = -5
Then we have the point (1, -5)
Now we just can graph these two points on a coordinate axis, and connect them with a line.

let f(x)= p+ 8/x-q. the line x=4 is a vertical asymptote to the graph of f. what is the value of q and p, if the y intercept is (0,4)?
Answer:
The value of q and p is 4 and -24 respectively.
Step-by-step explanation:
Being [tex]f(x)=\frac{p+8}{x-q}[/tex] , the line x=4 is a vertical asymptote to the graph of f(x). The line r is an asymptote of a function if the graph of the function is infinitely close to the line r. That is, an asymptote is a line to which a function approaches indefinitely, without ever touching it.
Being a rational function that which can be expressed as the quotient of two polynomials, a vertical asymptote occurs when the denominator is 0, that is, where the function is not defined. In this case:
x - q= 0
Solving:
x= q
Being the line x=4 the vertical asymptote, then
4=q
Then the function f (x) is:
[tex]f(x)=y=\frac{p+8}{x-4}[/tex]
The y intercept is (0,4). This is, x= 0 and y=4. Replacing:
[tex]4=\frac{p+8}{0-4}[/tex]
Solving:
[tex]4=\frac{p+8}{-4}[/tex]
4*(-4)= p+8
-16= p+8
-16 - 8= p
-24= p
The value of q and p is 4 and -24 respectively.
