The table shows ordered pairs for a polynomial function, f.
x f(x)f(x)
−2−2 30
−1−1 0
0 −2−2
1 0
2 30
3 160
4 510
What is the degree of f?,
Answer:
The degree of the polynomial function will be 4.
Step-by-step explanation:
The table shows the ordered pairs for a polynomial function, f.
[tex]x[/tex] -2 -1 0 1 2 3 4
[tex]f(x)[/tex] 30 0 -2 0 30 160 510
Now, to get the degree of the polynomial, it is required to get the difference of the value of function. When the value of the function becomes equal, then the number of step or difference will be its degree.
So, the first difference of the function will be,
[tex]0-30=-30\\ -2-0=-2\\0-(-2)=2\\30-0=30\\160-30=130\\510-160=350[/tex]
Now, the second difference of the function will be,
[tex]-2-(-30)=28\\2-(-2)=4\\30-2=28\\130-30=100\\350-120=220[/tex]
Now, the third difference of the function will be,
[tex]4-28=-24\\28-4=24\\100-28=72\\220-100=120[/tex]
Now, the fourth difference of the function will be,
[tex]24-(-24)=48\\72-24=48\\120-72=48[/tex]
So, the fourth difference of the function is equal and hence, the degree of the polynomial function will be 4.

A square lawn has area 512 ft squared .ft. a sprinkler placed at the center of the lawn sprays water in a circular pattern that just covers the lawn. what is the radius of the circle?
Answer:
Radius of circle = 16 ft
Step-by-step explanation:
Refer figure for the arrangement.
Area of square = 512 ft²
Side of square [tex]=\sqrt{512}=22.63ft[/tex]
From figure see that
Diagonal of square = Diameter of circle
[tex]\texttt{Diameter of circle}=\sqrt{22.63^2+22.63^2}=32ft[/tex]
Radius of circle [tex]=\frac{32}{2}=16ft[/tex]
If triangle DEF is translated 5 units down, what will be the coordinates of point E ′ in the image?
Answer: The correct option is
(B) (4, -2).
Step-by-step explanation: Given that the triangle DEF is translated units down.
We are to find the co-ordinates of point E' in the image.
From the graph, we note that
the co-ordinates of the vertices of triangle DEF are D(1, 2), E(4, 3) and F(3, 1).
We know that
if a point (x, y) is translated 5 units down, then its co-ordinates becomes
(x, y) → (x, y-5).
Therefore, after translation, the co-ordinates of the vertex E' in the image are
E(4, 3) → E'(4, 3-5) = E'(4, -2).
Thus, (B) is the correct option.
Answer:
(4 ,-2)

If f(x) = x2 + 1 and g(x) =x-4, which value is equivalent to (f•g)(10)
Answer:
(f•g)(10)= 606
Step-by-step explanation:
We have been given that
[tex]f(x)=x^2+1\\\\g(x)=x-4[/tex]
We have to find the value of (f•g)(10)
We can write (f•g)(10) = f(10)•g(10)
Let us find the value of the functions at x = 10
[tex]f(10)=10^2+1\\\\f(10)=100+1\\\\f(10)=101[/tex]
And the value of g(10) is
[tex]g(10)=10-4\\\\g(10)=6[/tex]
Hence,
(f•g)(10)
= f(10)•g(10)
= 101×6
= 606
Therefore, (f•g)(10)= 606

How many solutions exist for 3x^2 +4x + 2 = 0
Answer:
The given equation [tex]3x^2+4x+2=0[/tex] has exactly 2 solutions.
Step-by-step explanation:
Given : Equation [tex]3x^2+4x+2=0[/tex]
We have to find the number of solutions of the given equation [tex]3x^2+4x+2=0[/tex]
Consider the given equation [tex]3x^2+4x+2=0[/tex]
Since, The highest degree of the given polynomial is 2.
For a polynomial, the highest degree gives the number of solution of that polynomial.
So, [tex]3x^2+4x+2=0[/tex] has 2 solutions.
The given equation [tex]3x^2+4x+2=0[/tex] has exactly 2 solutions.

The value of x is -3.5 and y is 6.5 for the given equations.
What is an equation?An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
The equations will be solved as:-
−3x + y = 4
−9x + 5y = −1
Multiply the first equation by 3 and subtract the second equation.
−15x + 5y = 20
9x - 5y = -1
--------------------
-6x = 21
x = -3.5
Put x = -3.5 into first equation.
(-3x3.5) + y = 4
y = 6.5
Hence, the values are -3.5 and 6.5.

To solve this problem yo need to have the "x", the "y", and the radius. To find the radius since it is not given we use the formula.
sq rt(-3^2+1^2)
sq rt(9+1)
sq rt(10) would be the length of the radius in this case.
Then we use the sine cosine and tangent fractions
sin:y/r
cos:x/r
tan:y/x
With the values plugged in the equations are
SIN:1/sqrt(10) Since there can´t be a sq rt in hte denominator we change it to 1(sq rt(10))/10
COS:-3/sqrt(10) Since there can´t be a sq rt in the denominator we change it to -3(sq rt(10))/10
TAN:1/-3 This one can stay the same.
This would be the measures of SIN, COS, and TAN.

Evaluate x divided by 80 for x = 8/9. The choices are
A.71 1/9
B.1/9
C.9/640
D.90
@bohotness @chosenmatt @KamiBug @answermyquestions
I think the answer is either B or D,
The expression x divided by 80 for x = 8/9 is equal to 1/90.
Option D is the correct answer.
We have,
To evaluate x divided by 80 for x = 8/9, we substitute the value of x into the expression and perform the division:
(x) / 80 = (8/9) / 80
To divide fractions, we multiply the numerator by the reciprocal of the denominator:
(8/9) / 80 = (8/9) x (1/80)
Next, we simplify the multiplication:
(8/9) x (1/80) = 8 / (9 x 80) = 8 / 720
Simplifying the fraction further:
8 / 720 = 1 / 90
Therefore,
x divided by 80 for x = 8/9 is equal to 1/90.

A bag contains 4 green marbles and 5 white marbles. Suppose a marble is randomly selected. What are the odds in favor of picking a white marble ?
A. 4 to 5
B. 4 to 9
C. 5 to 4
D. 5 to 9
The odds in favor of picking a white marble from a bag of 4 green and 5 white marbles are 5 to 4.
To find the odds in favor of picking a white marble from a bag that contains 4 green marbles and 5 white marbles, first understand that 'odds in favor' are defined as the ratio of the number of ways the desired outcome can occur to the number of ways the desired outcome cannot occur. In this scenario, the desired outcome is drawing a white marble, and there are 5 white marbles. The number of ways the desired outcome can not occur is the number of non-white marbles, which is 4 green ones. Therefore, the odds in favor of drawing a white marble are 5 white marbles to 4 non-white marbles, or 5 to 4.
