please explain set in mathematics
Answer:
Set theory is the branch of mathematical logic that studies sets, which can be informally described as collections of objects. Although objects of any kind can be collected into a set, set theory, as a branch of mathematics, is mostly concerned with those that are relevant to mathematics as a whole.

Answer:
x = 8.45
Step-by-step explanation:
5.4 + 0.2x = 7.09
Subtract 5.4 from both sides to leave 0.2x alone
0.2x = 1.69
Divide by 0.2 on both sides to isolate x
x = 1.69/0.2
x = 8.45

Find the value of x
………..
Answer:
135°
Step-by-step explanation:
In a hexagon, sum of all angles = 720
x + x + x + x + 90 + 90 = 720
4x + 180 = 720
4x = 720 - 180

Are 2/3 and 8/12 equivalent ratios? If so, what can you multiply one by to get to the other?
Answer:
Yes
Step-by-step explanation:
Yes, since the relationship between the denominators can be expressed as x(4) = y, then you must apply this to the numerators as well. If you multiply 2 by 4 the result is 8, which aligns with the 2nd ratio - in fraction form.
I hope this helped a bunch! Tell me if you need any further assistance...
( :
Answer:
Yes
Step-by-step explanation:
2/3 and 8/12 are equal because of a multiplying factor. To get from 2 to 8, you'd have to multiply by 4. And to get from 3 to 12 you would have to multiply by 4 as well. So that means they are equal because both the numerator and denominator are multiplied by 4.

Which of the following formulas would use an absolute row reference when filled
=B4*B6
=B4/$B6
=$B4*B6
=B$4*B6
When filled, the formula that utilizes an absolute row reference is =$B4*B6. Option (A) B4*B6 is the correct answer.
How to use a formula for an absolute row?In the formula, the dollar sign before B locks the reference to column B, while the absence of a dollar sign before row number 4 allows the row reference to be adjusted when the formula is copied or filled down to other cells.
This means that when the formula is copied or filled down to the cells below, the row reference will stay the same as row 4, while the column reference will change based on the column of the new cell.
The formula =B4*B6, on the other hand, would include relative references to both the row and the column, thus when copied or filled down, both the row and column references would alter based on the new cell.
The formulas =B4/$B6 and =B$4*B6 would have an absolute column reference and a relative row reference, meaning that when copied or filled down, the column or row references, respectively, would stay the same or adjust based on the new cell.
Therefore, the formula =$B4*B6 is the one that uses an absolute row reference when filled.

To graph y=x^2-4, you would shift the graph of y=x^2 ____ a distance of ____ units?
Answer:
"To graph y = x² - 4, you would shift the graph of y = x² _down_ a distance of __4__ units.
Step-by-step explanation:
Start with the parent function
y = x²
When you substitute y - k for y, you are shifting the graph vertically k units.
The translated function is
y = x² - 4
Add 4 to both sides.
y + 4 = x²
y was substituted by y + 4.
We must write the substitution as y - k, so rewrite y + 4 as
y - (-4). Now compare y - (-4) with y - k.
k = -4
The vertical shift is -4, so the graph was translated 4 units down.
"To graph y = x² - 4, you would shift the graph of y = x² _down_ a distance of __4__ units.
To draw graph y = x² - 4, we shift the graph y = x² down a distance of 4 units.
What is Quadratic equation?
An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
Draw the graph y = x² - 4 with the help of graph y = x².
Now,
Since, The translated graph is,
y = x² - 4
Add 4 both side, we get;
y + 4 = x²
Clearly, y is substituted by y + 4.
Since, when we substitute y - k for y , then we shift k units down.
So, By comparing we get;
y + 4 = y - (-4)
The graph y = x² - 4 is shift down to 4 units.
Thus, To draw graph y = x² - 4, we shift the graph y = x² down a distance of 4 units.

Enter the value for x that makes the equation 2(x - 4) = 6x + 8 true
Answer:
x = -4
Step-by-step explanation:
2(x - 4) = 6x + 8
2x - 8 = 6x + 8
-4x - 8 = 8
-4x = 16
x = -4
Answer:
x = - 5.33
Step-by-step explanation:
2(x - 4) = 6x + 8 Remove the brackets
2x - 8 = 5x + 8 Subtract 2x from both sides
2x-2x - 8 = 5x - 2x + 8 Combine
- 8 = 3x + 8 Subtract 8 from both sides
-8 - 8 = 3x + 8 - 8 Combine
- 16 = 3x Divide by 3
-16/3 = 3x/3

This online calculator will calculate the various properties of a right circular cone given any 2 known variables. The term "circular" clarifies this shape as a pyramid with a circular cross section. The term "right" means that the vertex of the cone is centered above the base. Using the term "cone" by itself often commonly means a right circular cone.
Units: Note that units are shown for convenience but do not affect the calculations. The units are in place to give an indication of the order of the results such as ft, ft2 or ft3. For example, if you are starting with mm and you know r and h in mm, your calculations will result with s in mm, V in mm3, L in mm2, B in mm2 and A in mm2.
Below are the standard formulas for a cone. Calculations are based on algebraic manipulation of these standard formulas.
Circular Cone Formulas in terms of radius r and height h:
Volume of a cone:
V = (1/3)πr2h
Slant height of a cone:
s = √(r2 + h2)
Lateral surface area of a cone:
L = πrs = πr√(r2 + h2)
Base surface area of a cone (a circle):
B = πr2
Total surface area of a cone:
A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
Circular Cone Calculations:
Use the following additional formulas along with the formulas above.
