Intersection AND

Union AND, MOSTLY

Disjunction OR

Conjunction AND

For these words, we have:

Intersection, when we and the common results between two sets

So, Intersection A ∩ B A and B

A ={1,2,3} B= {3,4,5} A ∩ B ={3}

Disjunction, OR

When some conditions apply either to one set or to another.

A V B = OR

He is American OR He is British

A OR B

Union, AND, Mostly

When we want all the elements that belong to both Sets

So A ∪ B means A and all the elements from A and all the elements from B, no need no repeat the same element.

A = {1,2,3} B= {3,4,5} A ∪ B ={ 1,2,3,4,5}

Conjunction

A ^ B = AND,

In Logic and Set Theory and we have conjunction, we can use the word

He is a New Yorker AND He is American.

Answer:

x = 2

Step-by-step explanation:

4x - 3 = 5

4x = 8

x = 8/4

x = 2

------------

4 (2) - 3 = 5

8 - 3 = 5

5 = 5

answer: x = 2

Answer:

Step-by-step explanation:

The easiest and most proper way to approach this task is to combine like terms inside parentheses:  (24x + 7 – 12x) => (12x + 7).

Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7).  This is an acceptable answer.  There is the option of carrying out the multiplication, which results in

3x + 7/4, which is another acceptable answer.

Answer:

5. m∠A = 26

6. m∠D = 118

7. m∠E = 43

8. m∠H = 85

Step-by-step explanation: complementary= 90 supplementary = 180

5. (2x - 8) + (4x +4) = 90

6x - 12 = 90

6x = 102

x = 17

m∠A = 2x - 8  

m∠A = 2(17) - 8 = 26

6. (2x + 18) + (5x + 8) = 180

7x + 26 = 180

7x = 154

x = 22

m∠D = 5x + 8

m∠D = 5(22) + 8 = 118

7. (2x + 15) + (3x + 5) = 90

5x + 20 = 90

5x = 70

x = 14

m∠E = 2x + 15

m∠E = 2(14) + 15 = 43

8. (5x - 20) + (4x + 7 ) = 180

9x - 27 = 180

9x = 207

x = 23

m∠H = 4x -7

m∠H = 4(23) - 7 = 85

It is the set of all real numbers from 0 to 10.which describes the domain of this function

What is Domain of function?

A function's domain is the collection of all potential inputs. For instance, all real numbers are in the domain of f(x)=x², and all real numbers are in the domain of g(x)=1/x, with the exception of x=0. Special functions with more constrained domains can also be defined.

According to Question

Given graph represents the profits, in dollars, John has made with his lawn mowing company, as a function of time

Therefore the domain of the function is the time which john has owned the company which is equals to 10 years

We can infer from the foregoing description that the typical annual cost of living for a retiree is (A) around $50,000.

One who has retired is known as a retiree.

Many seniors underestimate their retirement income by not accounting for inflation.

Wages, a gauge of the income that retirees must replace, will be the basis for benefits.

One who has retired is known as a retiree.

The required bearing angle of town B from Thomas is 75°.

We have,

Bearing is basically an angle that is measured clockwise from the north. Bearing are generally written in three figure.

Given that

Thomas is facing towards town A, which is at a bearing of 300°.

Implies that town A is 300° from north.

If Thomas turns 135° clockwise, then he faces towards town B,

The bearing angle will be 300+135 = 435°

Since, one complete round makes angle 360°, therefore

The required bearing angle = 435 - 360 = 75

The given equation is frac{13}{4x-4}=\frac{2}{x-1}+\frac{x+4}{8}. To solve for x, we first simplify the right-hand side by finding a common denominator. Multiplying the second term by frac{2}{2} and the third term by frac{x-1}{x-1}, we get:

frac{13}{4x-4}=\frac{2\cdot 8}{8(x-1)}+\frac{(x+4)(x-1)}{8(x-1)}

Simplifying the right-hand side, we get:

frac{13}{4x-4}=\frac{16}{8(x-1)}+\frac{x^2+3x-4}{8(x-1)}

Combining like terms, we get:

frac{13}{4x-4}=\frac{2x+12+x^2+3x-4}{8(x-1)}

Simplifying, we get:

13(8)=(2x+12+x^2+3x-4)(4x-4)

Expanding the right-hand side and simplifying, we get:

13(8)=4x^3-5x^2-23x+100

This is a cubic equation, which can be solved using various methods such as factoring, the rational root theorem, or numerical methods.

In summary, the given equation frac{13}{4x-4}=\frac{2}{x-1}+\frac{x+4}{8} can be solved by simplifying the right-hand side, combining like terms, and simplifying again to obtain a cubic equation. Various methods can be used to solve the cubic equation and find the value(s) of x.

The required  cost of each shirt is $21.28.

A mathematical statement known as an equation is made up of two expressions joined together by the equal symbol. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the quantity x is 7.

The total cost of 3 identical shirts, including shipping, is $71.83. So we can write the equation as:

3s + 7.99 = 71.83

To solve for the cost of each shirt, we need to isolate the variable "s" on one side of the equation. We can start by subtracting 7.99 from both sides:

3s = 63.84

Then, we can divide both sides by 3:

s = 21.28

Therefore, the cost of each shirt is $21.28.

Pack of 6 apples for £1.65 is better because the price of 1 apple is less in this answer.

The coordinate points of x and Y of the given system of equations is x= -1 and Y = 1.

The system of equations are,

Y= -3x-2      _____ (1)

Y= -6x-5      _____ (2)

Solving the given system of equations by applying  elimination method,

Multiplying equation (1) by 2 and equation (2) by 1, we get,

2Y= -6x-4      _____ (3)

Y= -6x-5      _____ (4)

Subtracting equation (4) from equation (3), we get,

2Y - Y = ( -6x-4  ) - ( -6x-5)  

⇒Y = -6x - 4 + 6x + 5

⇒Y = 1

Putting Y= 1 in equation (1), we get,

1 = -3x - 2

⇒ -3x = 1 +2

⇒ -3x = 3

⇒ x = -3/3

⇒ x = -1

Hence the coordinate points of x and Y are -1 and 1 respectively.

The direction of the force on the bottom section of the rotor can be determined using the right-hand rule for magnetic forces.

According to the right-hand rule, if you point your thumb in the direction of the current flow (clockwise in this case), and your fingers in the direction of the magnetic field (vertically into the magnet), then the direction of the force will be perpendicular to both the current and the magnetic field.

In this case, if you imagine your thumb pointing in the clockwise direction and your fingers pointing vertically into the magnet, the force on the bottom section of the rotor will be directed towards the center of the motor.

Therefore, the direction of the force on the bottom section of the rotor will be towards the center of the motor.

An inverse does not exist for a parabola.

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics.

It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves.

An inverse does not exist for a parabola.

One definition of a parabola includes a line and a point (the focus) (the directrix).

The directrix is not the main focus.

The locus of points in that plane that are equally spaced apart from the directrix and the focus is known as the parabola.

A right circular conical surface and a plane parallel to another plane that is tangential to the conical surface intersect to form a parabola, which is also known as a conic section.

Therefore, an inverse does not exist for a parabola.

The value of x=5!

Step-by-step explanation:

I remeber ing this!!!:)

The closest value of sec A, where A is an angle whose terminal ray passes through the point (0.28, 0.96) on the unit circle, is approximately 3.43.

The unit circle is a circle with a radius of 1 centered at the origin (0, 0) in the coordinate plane. The point (0.28, 0.96) lies on the unit circle, which means it forms an angle A with the positive x-axis.

To find the value of sec A, we need to determine the reciprocal of the cosine of angle A. Since the point (0.28, 0.96) lies on the unit circle, its coordinates correspond to the cosine and sine of angle A, respectively.

The cosine of angle A is the x-coordinate of the point, which is 0.28. Therefore, sec A is the reciprocal of 0.28, which is approximately 3.57.

Among the given answer choices, the value of sec A closest to 3.57 is approximately 3.43 (option 3).
