What is root 4 called?

The union of two sets is to avoid counting the same elements twice.

The mathematical logic subfield of set theory investigates sets, which can be loosely defined as collections of objects. Although any object can be combined into a set, set theory, as a mathematical discipline, focuses primarily on those that are relevant to mathematics as a whole.

Given union of set

(A ∪ B),

The set of all objects that are members of either A or B, or both, is the union of the sets A ∪ B.

let us take example,

A = { 1, 2, 3, 4}

B = {3, 4, 5, 6, 7}

(A ∪ B) = { 1, 2, 3, 4} ∪  {3, 4, 5, 6, 7}

we can simply write all of A and B's elements in a single set to avoid duplicates to find A U B.

(A ∪ B) = {1, 2, 3, 4, 5, 6, 7}

Hence the  union of two sets is a set that contains all the elements of both set and avoid duplicates.

There are two zeros of the polynomial 2x²-3x+4.

Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables

The given polynomial is 2x²-3x+4.

Two times of x square minus three times of x plus four.

To find the x-intercept of a linear equation in two variables we set y intercept to 0.

When we are given with a two variable linear equation, we plug 0 in place of y and solve the equation to get the x-intercept of that linear equation.

For example, let us consider the linear equation 2x + 3y = 4

To get the x-intercept of the equation 2x + 3y = 4 we would plug y = 0.

Therefore, 2x + 3(0) = 0

⇒ 2x + 0 = 4

⇒ x = 4/2 = 2

Thus, the x-intercept of the linear equation 2x + 3y = 4 is 2.

Therefore , the solution to the given problem of the equation whose factors are (x+2)(x+1)(x+3).

Describe equation.

Two expressions joined by an equal sign form a mathematical statement known as an equation.

An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.

According to the Given question:

x³ + 6x² + 11x +6

This pattern of coefficients 1, 6, 11, 6 is actually one that you are likely to encounter frequently.

For demonstration reasons, let's see what occurs if we begin by using the typical technique for resolving a general cubic:

We can use a linear substitution, t = x + b/3a, to simplify any cubic of the form ax3 + bx2 + cx + d, resulting in a cubic in the form a + b + et + f without a quadratic term.

This is the most straightforward type of Tschirnhaus transformation.

In our example, a = 1 and b = 6, so we want t = x + 2.

Note that:

=  + 6+ 12x +8

So we find:

+ 6+ 11x +6 =   − (x + 2)

=  - t

= t ( - 1)

= t(t − 1)(t + 1)

= (x+2)(x+1)(x+3)

Step-by-step explanation:

⭐ [tex]g(x) = (x-h)^2 + k[/tex] is already written in vertex form.

⭐ Vertex form: [tex]f(x) = a(x-h)^2 +k[/tex], where the vertex is (-(-h), k)

We are already given the vertex (9,-8), so we have to substitute these numbers into g(x).

The equation of parabola is solved and the values of h and k are 9 and -8 respectively

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

y = a ( x - h )² + k

where ( h , k ) is the vertex and ( h , k + p ) is the focus

y is the directrix and y = k – p

The equation of the parabola is also given by the equation

y = ax² + bx + c

where a , b , and c are the three coefficients and the parabola is uniquely identified

Given data ,

The vertex form of a parabola function is given by:

g(x) = a(x - h)² + k

where (h, k) is the vertex.

In this case, we are given that:

g(x) = (x - h)² + k

And the vertex is located at (9, -8)

So we have:

h = 9

k = -8

Therefore, the function g(x) can be written as:

g ( x ) = ( x - 9 )² - 8

The solution of 3 drops of yellow food coloring needed to make a shade of orange icing with 9 drops of red food coloring is 72/24

The formula for calculating the number of drops of yellow food coloring required to make a shade of orange icing would be:

Yellow Food Coloring Drops = (Red Food Coloring Drops x 8) / 24

In this example, we are using 9 drops of red food coloring. To calculate the number of drops of yellow food coloring needed, we would plug in 9 for the number of drops of red food coloring, resulting in the following equation:

Yellow Food Coloring Drops = (9 x 8) / 24

We can solve this equation by multiplying both sides by 24 to get:

Yellow Food Coloring Drops x 24 = 9 x 8

We can further simplify the equation by multiplying the numbers on the right side of the equation to get:

Yellow Food Coloring Drops x 24 = 72

Finally, we can solve for the number of drops of yellow food coloring by dividing both sides of the equation by 24 to get:

Yellow Food Coloring Drops = 72/24

Given,

If quadrilateral ABCD is rotated 90° clockwise about point A and then reflected across the y-axis to create quadrilateral A’B’C’D’.

In order to find the new coordinates, first we have to identify the current coordinates of the quadrilateral.

A (0,0), B(-4, 3), C(1,5) and D(2,3)

Now, we have to use the rule of clockwise 90° rotation, states that to rotate the figure 90 degrees clockwise about a point, every point(x , y) will rotate to (y, -x).

According to this rule, the new coordinates are written as,

A(0,0) = A'(0,0)

B'(-4,3) = B'(-3,-4)

C(1,5) = C'(5, -1)
