Consider the linear equation. 5x+6y=−15 Which point represents a solution to the equation?

The domain and range of the given quadratic function are respectively; Domain = -3 < x < 7; Range is; 3 ≤ x ≤ ∞

The domain of a function is defined as the set of all possible input values for which the function is possible.

Meanwhile, the range is defined as the set of all possible output values for every possible input value that makes the function possible.

Now, from the graph, the range will be values on the y-axis while the domain will be values on the x-axis.

Now, from the given graph we see that the curve is approaching the lines x = -3 and x = 7. Thus, the domain of this function is;

The given function is f (x) = e + cos x - 1,

f' is the derivative of the given function, and the derivative is sort for below

f (x) = e + cos x - 1

f' (x) = 0 + -sin x - 0

f' (x) = -sin x

for f' (2) we substitute the x = 2 in the derivative

f' (x) = -sin x

f' (2) = -sin 2

If the degree of the polynomial function is an even number and the leading coefficient is negative, the graph will have an even number of turning points and will be concave down. The graph will also have a single x-intercept at the origin, and the y-intercept will be negative.

A graph of polynomial functions with an even degree and negative leading coefficient will have an even number of turning points and will be concave down. A turning point is the point on a curve where the curve changes direction, and a concave down shape means that the curve is curved down from left to right. The graph will have a single x-intercept at the origin, which is the point where the graph crosses the x-axis. The y-intercept of the graph will also be negative, which is the point where the graph crosses the y-axis. This graph will have a negative slope and will decrease as it moves away from the origin. The graph will approach the x-axis but will not touch it, creating a U-shaped curve. The graph will also have a maximum or minimum value, depending on the specific values of the polynomial function.

Angles are 7 types.

1.Acute Angle: An acute angle is any angle that is less than 90 degrees and is between 0 degrees and 90 degrees. 

2.Obtuse Angle: Opposite of an acute angle is an obtuse angle. In other terms, an obtuse angle is one that is larger than 90 degrees and less than 180 degrees. It is the angle that is between 90 degrees and 180 degrees.

3. Right Angle: A right angle is always 90 degrees in length. Acute angles are those that are less than 90 degrees, whereas obtuse angles are those that are higher than 90 degrees. 

4. Straight Angle: A straight angle has a measured angle of 180 degrees. Since the angle between its arms is 180 degrees, you can see that it is simply a straight line.

5.Reflex angle: The arms make an acute angle because this measurement is less than 90 degrees. What about the angle on the opposite side, though? What is the name of the larger angle that complements the acute angle? It is referred to as a reflex angle.

A reflex angle is any angle having a dimension higher than 180 degrees but less than 360 degrees (which corresponds to 0 degrees).

6.Complete Rotation: Entire rotation or full angle refers to an angle with a value of 360 degrees. When one of the arms extends completely, it is created.

7.Null angle: Angle of 0 degrees is null angle.

The vertex of the parabola equation is (5, 43) and the parabola standard form is y = 2x² + 20x + 43.

What is Parabola?

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed-line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.

We have,

The parabola standard from f(x) = a(x-h)² + k

f(x) = 2x² + 20x + 43

The general equation of a parabola is y = a(x - h)² + k or x = a(y - k)² +h, where (h,k) denotes the vertex.

Consider an equation y = 2x² + 20x + 43. For this parabola, a = 2 , b = 20 and c = 43. which is a parabola.

Vertex: (h, k)

h = -b/2a

= 20/(2 × 2)

= 5

k = f(h)

= f(5) = 2(5)² + 20(5) + 43

= 50 + 100 + 43

Thus vertex is (5, 43)

Hence, the vertex of the parabola equation is (5, 43) and the parabola standard form is y = 2x² + 20x + 43.

Translation, rotation, reflection, and dilation are the four basic forms of transformations.

By rotating, reflecting, or translating a shape on a coordinate plane, a transformation is made. A fresh viewpoint on geometry known as transformational geometry was put forth by Felix Klein in the 19th century.

The transformation is f: X X, which stands for a function, f, that maps to itself. The transformation causes the pre-image X to change into the picture X. Translation, rotation, reflection, and dilation are only a few examples of the transformations that can be used alone or in combination. A function is translated when it is moved in one direction, rotated when it is spun around a point, reflected when it is turned into the opposite of itself, and dilated when it is scaled. Two-dimensional geometrical figures can move about a coordinate plane via mathematical transformations.

Hence, Translation, rotation, reflection, and dilation are the four basic forms of transformations.

A "matching" figure is one that can be placed perfectly on another. The bread has the same size and form when it is stacked. Match refers to objects that are precisely the same size and form. If one of two geometric figures can be consistently overlaid on the other, they are said to be congruent or to be in a congruent relationship.

The roots of the quadratic equation are real and distinct

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

2x² + 4x - 7 = 0   be equation (1)

On simplifying the equation , we get

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

Substituting the values in the equation , we get

x = [ -4 ± √ ( ( 4 )² - 4 ( 2 ) ( -7 ) ) ] / 2 ( 2 )

On simplifying the equation , we get

x = [ -4 ± √ ( 16 + 56 ) ] / 4

x = [ -4 ± 6√2 ] / 4

x = ( -2 + 3√2 ) / 2

And ,

x = ( -2 + 3 ) / √2

Therefore , the roots are x = ( -2 + 3√2 ) / 2 and x = ( -2 + 3 ) / √2

y = x + 6 and 3x - 3y = -18 .... Infinitely many solutions.

y = -2x + 5 and 2x + y = -7 .... No solution.

y = -4x + 11 and -6x + y = 11 ... One solution.

Solving equations

y = -4x + 11 ....... equation i

-6x + y = 11 ...... equation ii

Put equation i into ii.

-6x + y = 11

-6x + (-4x + 11) = 11

-6x - 4x + 11 = 11

-6x - 4x = 11 - 11

-10x = 0

x = 0

Therefore,

x = 0 and y = 11.

This gives a solution for each variable.

y = -2x + 5 ..... i

2x + y = -7 ..... ii

Put equation i into ii

2x + y = -7

2x + (-2x + 5) = -7

2x - 2x = -7 - 5

0 = -12

This indicates no solution.

y = x + 6 ..... i

Put equation i into ii

3x - 3y = -18

3x - 3(x + 6) = -18

3x - 3x - 18 = -18

According to the question we assume the number of reindeer are x and number of elves are y.

Total 37 elves are helping Santa. There are a total of 58 reindeer and elves helping Santa get ready for Christmas hence the equation of given condition is as follows:

x + y=58

Each reindeer has 4 legs and each elf has 2 legs counted 158 legs when all the reindeer and elves were in Santa’s workshop helping Santa. Hence the equation of given condition is as follows:

4x+2y=158

By solving both the above equation multiplying first equation by 2

2x+2y=116

Subtract both the above equation
