The table shows ordered pairs of the function . What is the value of y when ? A 2-column table with 6 rows. The first column is labeled x with entries negative 3, negative 1, 1, 4, 8, 10. The second column is labeled y with entries 14, 10, 6, 0, question mark, negative 12. –20 –8 8 48
Answer: b?
Step-by-step explanation:
I think it b on edg.
The table of ordered pair is an illustration of a linear function.
The value of y when x = 8 is -8
From the table (see attachment), we have the following highlights
As x increases by 2, y decreases by 4As x decreases by 2, y increases by 4When x = 10, y = -12
So, when x decreases by 2 (to 8), the value of y will increase by 4 (to -8).
Hence, the value of y when x = 8 is -8

Answer:
3. 12.5π + 100
6. 25π + 250
Step-by-step explanation:
3. So you can first calculate the area of the square, which is 100.
Then you have to calculate the semicircle.
You can see that the diameter is 10.
The radius is 5.
The area of the semicircle is 12.5π
Total area is 12.5π + 100
6. You have a one rectangle and two semicircles.
You can calculate the area of the semicircles first.
25π
Then, you have to see how much the width of the rectangle is.
You can see that the total width is 35, and the radius of each semicircle is 5.
35 - 5 - 5 = 25
The width is 25 so the area of the rectangle is 250.
The total is 25π + 250.

A line is drawn through (-4, 3) and (4, 3). Which describes whether or not the line represents a direct variation?
O The line represents a direct variation because
O The line represents a direct variation because it is horizontal.
O The line does not represent a direct variation because it does not go through the origin.
O The line does not represent a direct variation because -4(3) = 4(3)
Answer:
third option
Step-by-step explanation:
A graph representing direct variation must pass through the origin.
The graph through (- 4, 3) and (4, 3) is a horizontal line and does not go through the origin.
Thus the line does not represent a direct variation because it does not go through the origin.

1.) Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
2.) Write the equation of the line of best fit using the slope-intercept formula y = mx + b. Show all your work, including the points used to determine the slope and how the equation was determined.
3.) What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
4.) Test the residuals of two other points to determine how well the line of best fit models the data.
5.) Use the line of best fit to help you to describe the data correlation.
6.) Using the line of best fit that you found in Part Three, Question 2, approximate how tall is a person whose arm span is 66 inches?
7.) According to your line of best fit, what is the arm span of a 74-inch-tall person?
Answer:
1) On the x-axis, the arm span is plotted. On the y-axis, the height is plotted. It is chosen to be that way because the numbers on that have been assigned on the x-axis increase and decrease in a small amount, while the numbers on the y-axis increase and decrease in a huge amount.
2) (lolz i cant show u my work but i will try my best with explanations even tho ian allat.) So, Using the slope formula, I got a the equation y=x+15. The equation was determined with the formula m=y2-y1/x2-x1. The points that were used included (37,40) and (47,50). After finding the slope, I did the best guess for the y-intercept, which is known as b in y=mx+b.
3) The slope of the line represents the time it takes for the arm span and the height. The y-intercept represents the height that the arm span starts developing or gets bigger.
4) It fits perfectly
5) The data is pretty inconsistent.
6) About 68-69 inches tall
7)About 71-72 inches wide

Answer:
9 degrees Celsius
Step-by-step explanation:
I graphed the function on the graph below to find the maximum of the parabola. The maximum is at (9,200), which means at 9 degrees Celsius, there are 200,000 fish.
The temperature at which there will be maximum number of fishes is given by the point (9, 200), is it is 9 degrees.
Given data:
To find the temperature that will result in the maximum number of fish, determine the x-value (temperature) at the vertex of the quadratic function.
The given function is P(x) = -2(x - 9)² + 200, where P(x) represents the fish population in thousands and x represents the water's temperature.
The general form of a quadratic function is y = a(x - h)² + k, where (h, k) represents the vertex of the parabola.
The vertex form of the function is P(x) = -2(x - 9)² + 200.
Comparing this to the general form, the vertex of the parabola is at the point (9, 200).
Hence, the temperature that will result in the maximum number of fish is 9 degrees (the x-value of the vertex).

find K if the sum of the zeros of the polynomial x square - (K + 6 ) x + 2( 2 k - 1) is half the product
k=7
given a quadratic polynomial
ax^2+bx+c
the sum of the roots is given by -(b/a)
and the product of the roots as (c/a)
hence we get sum of roots as -(-(k+6)/1) and product of roots as (2(2k-1))/1
since the sum is equal to half the Product then we get
k+6=2k-1 and solving for k we get 7
You want to have your carpet cleaned in your living room which measures 12’ by 14’. Company A charges $2.75 per square foot and company B charges $450 per room. Which company should you hire to get a better deal?
Answer: Company B
Step-by-step explanation:
First we must calculate the area of the carpet. Variable A represents area.
[tex]14*12=A[/tex]
[tex]A=168[/tex]
So the area of the carpet is 168 square feet.
To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.
[tex]168*2.75= Company A\\[/tex]
Company A charges, $462, while Company B will charge $450 for the one room.
This means Company B has the better price.

C
the rates are the same
Answer:
(A ) Oldies
Step-by-step explanation:
Goodies
First, we determine the revolution rate per minute of the Goodies.
Revolution rate per minute [tex]=$Number of Revolutions \div $Number of Minutes[/tex]
[tex]=\dfrac{135}{3} =\dfrac{180}{4} =\dfrac{225}{5}=45$ revolutions per minute[/tex]
Since the oldies have a rate of 78 revolutions per minute;
78 rpm. >45 rpm.
We therefore conclude that the Oldies has a greater rate of revolutions per minute.
The correct option is A.

Find the range of p in equation p(x+1) (x-3)=x-4p-2 has no real roots.
Answer:
[tex]\displaystyle p > \frac{1}{4}[/tex].
Step-by-step explanation:
Expand the left-hand side of this equation:
[tex]p\, (x + 1)\, (x - 3) = p\, \left(x^2 - 2\, x - 3\right) = p\, x^2 - 2\, p\, x - 3\, p[/tex].
Collect the terms, so that this quadratic equation is in the form [tex]a\, x^2 + b\, x+ c = 0[/tex]:
[tex]p\, x^2 - 2\, p\, x - 3\, p = x - 4\, p - 2[/tex].
[tex]p\, x^2 - (2\, p + 1)\, x + (p + 2) = 0[/tex].
In this equation:
[tex]a = p[/tex].[tex]b = -(2\, p + 1)[/tex].[tex]c = p + 2[/tex].Calculate the quadratic discriminant of this quadratic equation:
[tex]\begin{aligned}b^2 - 4\, a\, c &= (-(2\, p + 1))^2 - 4\, p\, (p + 2) \\ &= 4\, p^2 + 4\, p + 1 - 4\, p^2- 8\, p = -4\, p + 1\end{aligned}[/tex].
A quadratic equation has no real root if its quadratic discriminant is less then zero. As a result, this quadratic equation will have no real root when [tex]-4\, p + 1 < 0[/tex]. Solve for the range of [tex]p[/tex]:
[tex]\displaystyle p > \frac{1}{4}[/tex].
