Find the centroid of the region in the first quadrant bounded by the x-axis, the parabola y2=8x , and the line x+y=6.
Coordinates of the centroid are (_,_).
The centroid of the region is (3,1).
The centroid of a region is a point that is the average of all the vertices of the region. In other words, it is the point that is the center of mass of the region. To find the centroid of a region, we need to find the x and y coordinates of the vertices of the region and then take the average of these coordinates.
To find the centroid of the region in the first quadrant bounded by the x-axis, the parabola y^2 = 8x, and the line x + y = 6, we need to find the x and y coordinates of the vertices of the region.
The parabola y^2 = 8x and the line x + y = 6 are the equations of the boundaries of the region. We can find the vertices of the region by solving for the points where these two equations intersect.
The parabola y^2 = 8x can be rewritten as y = ±√8x. So the x-coordinate of the vertex of the parabola is (3,3).
The line x + y = 6 can be rewritten as y = -x + 6. So the x-coordinate of the vertex of the line is (0,6) and (6,0).
So the three vertices of the region are (0,0), (3,3), and (6,0).
To find the x-coordinate of the centroid, we take the average of the x-coordinates of the vertices: (0 + 3 + 6)/3 = 3To find the y-coordinate of the centroid, we take the average of the y-coordinates of the vertices: (0 + 3 + 0)/3 = 1So the centroid of the region is (3,1).

How do you decide whether to use absolute values or the distance formula to find the distance between any two given locations on the coordinate plane?
The absolute value will be used over distance coordinate formula when the line is parallel to either the y-axis or x-axis.
How to find the distance between two coordinates?The common formula to find the distance between two coordinates is expressed as;
D = √[(x₂ - x₁)² + (y₂ - y₁)²]
Now, this formula is very useful when the two coordinates don't have their x coordinates equal or y coordinates equal and when the line is parallel to either the y axis or x axis.
When we have a case where the line is parallel to wither the y or x axis, then it is pertinent to note that if one coordinate is negative and the other is positive, we know that opposites have the same distance from zero, hence have the same absolute value.
Thus, we can find the absolute value to get the length.

What is the function notation?
Function notation is a way of writing mathematical functions using a specific syntax. A function is a rule that assigns a unique output to each input. In function notation, the function is represented by a letter, usually f, g, or h, followed by a variable in parentheses.
To find (f g)(x), we first need to find g(x) by substituting the value of x into the equation for g(x) = x^2 - 7:
g(x) = x^2 - 7
Next, we substitute the result of g(x) into the equation for f(x) = 2x + 1:
(f g)(x) = f(g(x)) = f(x^2 - 7) = 2(x^2 - 7) + 1
So the final result is (f g)(x) = 2x^2 - 14 + 1 = 2x^2 - 13
Hence, (f g) (x) = 2x^2 - 13

The table shows monthly costs for two different internet service providers. What will be the difference in cost of the two plans after 18 months
Answer: 240
Step-by-step explanation:
The difference in cost between the two plans after 18 months is $240.
This is because the cost of Company A is consistently $35 more per month than that of Company B, which therefore would add up to $630 after 18 months.
The linear equation representing the cost of Company A is Y = 35X + 40, while the linear equation representing the cost of Company B is Y = 50X.
After 18 months, X would equal 18, and substituting this value into the two equations, we get the following for Company A:
Y = 35X + 40 Y = 35 * 18 + 40 Y = 630Meanwhile, for Company B, we get:
Y = 50X Y = 50 * 18 Y = 900The difference between these two values for different internet service providers is:
= $900 - $630 = $240This question should be provided with this following data:

If there are 26 cubic inches of popcorn within the box, it will be 76% full.
What is a rectangular prism's volume?Volume is a unit used to describe how much room an object occupies. For instance, because two shoe boxes use twice as much space as one, they have twice as much volume.
Multiplying a rectangular prism's length, width, and height yields its volume. Volume of a rectangular prism is calculated as follows: Volume = Length x Width x Height
[tex]$$\begin{aligned}& \text { Volume }=2 \frac{1}{2} * 2 \frac{3}{4} * 5 \\& \text { Volume }=\frac{5}{2} * \frac{11}{4} * 5\end{aligned}$$[/tex]

A rectangle’s opposite sides are equal and parallel. Because a rectangle is a 2-D form, it has two dimensions: length and breadth. The length of the rectangle is the longer side, while the width is the shorter side. Square units of measurement include square inches, square feet, and square meters.

Step-by-step explanation:
1/3(x+7)=5 1/3
5 1/3=16/3
1/3(x+7)=16/3
x+7=(16/3)/(1/3)
x+7=(16/3)(3/1)
x+7=16/1
x+7=16
x=16-7
x=9
Answer:
x = 9
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ (1/3)(x + 7) = 5 1/3
Then the value of x will be,
→ (1/3)(x + 7) = 5 1/3
→ (x + 7)/3 = 16/3
→ x + 7 = (16/3) × 3
→ x + 7 = 48/3
→ x + 7 = 16
→ x = 16 - 7
→ [ x = 9 ]
Hence, the value of x is 9.

If f(x) =sqaureroot of x , which equation describes the graphed function?
As a result, if [f(x) is (x)], then the equation [y is f(-x + 2)] defines the graphed function.
which equation describes the graphed function?[y = f(-x + 2)] is the equation that describes the graphed function.
As stated in the question, a reference graph diagram and details on the function f(x), which equals the square root of "x," are given.
From the four possibilities provided, we are expected to select the equation that best explains the graphed function.
We will employ the trial-and-error approach to this problem, employing the possibilities to identify the best solution.
First off, the graph's x-axis and y-axis are both broken at (4, 0) and respectively (0, 2). As a result, [y = f(x)] requires that our equation be equal to 0 when (x = 4) is replaced and to 2 when (x = 0).
Taking into account option (A), we obtain, by substituting (x = 4) for (y = f[(- x) + 4] = sqrt[(- x) + 4]
y = sqrt[(- 4) + 4]
furthermore, y = sqrt (4 - 4)
furthermore, y = sqrt (0)
or, y = 0
The result of replacing (x = 0) is y= [(-0)+4]
or y = sqrt(4) or y = 2 or y = (4-0)
As a result, option (A) is satisfied at locations (4, 0) and (0, 2).
Similar results may be obtained for the other three possibilities by substituting and checking: for (x = 4), (y 0), and for (x = 0), (y 2).
As a result, if [f(x) = (x)], then the equation [y = f(-x + 2)] defines the graphed function.
A function in mathematics is an operator that, given an input, will carry out a predetermined series of operations.
