The exponential  is a mathematical function denoted by the argument x is written as an exponent. Unless otherwise specified, the term generally refers to the positive-valued function of  a true  variable, although it  are often  extended to the complex numbers or generalized to other mathematical objects like matrices or Lie algebras. The  exponential  originated from the notion of exponentiation (repeated multiplication), but modern definitions (there are several equivalent characterizations) allow it to be rigorously extended  to all or any  real arguments, including irrational numbers. Its ubiquitous occurrence in pure and  applied math  led mathematician Walter  to opine that the exponential function is "the most important function in mathematics".

Given that ∠ADB and ∠CDB are complimentary angles, the numerical measure of angle CDB is 25 degrees.

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

Given that;

Since ∠CDA is a right triangle, the sum of ∠ADB and ∠CDB sums up to 90 degrees.

∠ADB + ∠CDB = 90°

(7x +2) + (3x - 2) = 90

Solve for x

7x +2 + 3x - 2 = 90

7x + 3x - 2 +2 = 90

10x = 90

x = 90/10

x = 9

Now, the numerical measure of angle CDB will be;

m∠CDB = (3x - 2)

Plug in x=9

m∠CDB = 3(9) - 2

m∠CDB = 27 - 2

m∠CDB = 25 degrees

Given that ∠ADB and ∠CDB are complimentary angles, the numerical measure of angle CDB is 25 degrees.

$2950 is the monthly salary of the other employee.

a. the given information = mean of two salaries =  3210

                                        = salary of 1st employee =3470

the unknown information = salary of 2nd employee = 2950

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

We know that mean, [tex]m = \frac{\text{sum of the terms}}{\text{number of terms}}[/tex]

Here is given the

mean = 3210

term₁ = 3470                 (salary of one of the employees)

term₂ = ?                          (salary of the 2nd employee)

So, if we simplify

⇒ [tex]m = \frac{\text{sum of the terms}}{\text{number of terms}}[/tex]

⇒ [tex]3210 = \frac{3470 + term_2}{2}[/tex]

⇒ [tex]3210[/tex] × [tex]2 = 3470 + term_2[/tex]

⇒ [tex]6420[/tex] = [tex]3470 + term_2[/tex]

According to the given statement;

object A is moving faster by 8.184-5= 3.184

3.184 mph faster.

The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed only has a direction and no magnitude, it is a scalar quantity.

The most crucial scientific concept is measurement. Base or physical fundamental units are used to measure a wide range of measurable quantities. One such measurable quantity is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance. Let's explore speed in-depth in this session.

According to the given valus;

Speed of object A = 12 ft per sec

I foot per second = 0.682 mph

12 ft per sec = 0.682x 12

= 8.184 mph

object В speed = 5 mph

object A is moving faster than B.

object A is moving faster by 8.184-5= 3.184

Answer:  It is not always true, so it's not an identity

========================================================

Explanation:

Let's try replacing each 'a' with 1, and each b with 2. Feel free to pick two of your favorite nonzero numbers.

So we'll plug in a = 1 and b = 2

[tex](a+b)^2 = a^2+b^2\\\\(1+2)^2 = 1^2+2^2\\\\(3)^2 = 1^2+2^2\\\\9 = 1+4\\\\9 = 5\\\\[/tex]

The last equation is a false statement. This means the first equation is also false for a = 1 and b = 2.

This is one counter-example to disprove that (a+b)² = a² + b² is true in general.

Therefore, the equation is not an identity.

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

What is an identity however is this

(a+b)² = a² + 2ab + b²

If you were to plug in a = 1 and b = 2, then you'd get 9 on each side. This is one example to help partially confirm it's an identity.

More rigorous proof is in the form of using the FOIL method, the distributive property, or the box method.

The transformation used to map AB to A'B' is not a rigid transformation since the measure of AB is greater than the measure of A'B' and not equal.

Transformation is the movement of a point from its initial location to a new location. Types of transformations are reflection, rotation, translation and dilation.

A rigid transformation is a transformation that preserves the shape and size such as rotation, reflection and translation.

Given the points A(-1, 13), B(1, 5), A'(2, 3), and B'(6, 1), hence:

[tex]AB=\sqrt{(5-13)^2+(1-(-1))^2} =\sqrt{68}\\\\A'B'=\sqrt{(1-3)^2+(6-2)^2}=\sqrt{20}[/tex]

The equation of the line that is perpendicular to given line is y = -x -2

From the question, we are to determine the equation of the line

From the given information,

We have that the two lines are perpendicular

If two lines are perpendicular, the product of their slopes is -1

That is,

m₁m₂ = -1

Where m₁ is the slope of the first equation

and m₂ is the slope of the second equation

In the given equation,

y = x - 2

Compare to the general form of the equation of a line

y = mx + b

Where m is the slope

and b is the y-intercept

Thus,

In the equation, y = x - 2

Slope = 1

Therefore,

The slope of the equation we are to determine is -1

Also, from the given information,

The line passes through the point (-12, 10)

Using the point-slope form of a line

y - y₁ = m(x - x₁)

x₁ = -12

y₁ = 10

Thus,

y - y₁ = m(x - x₁)

y - 10 = -1(x - -12)

y - 10 = -1(x + 12)

y - 10 = -x -12

y = -x -12 + 10

y = -x -2

Hence, the equation of the line that is perpendicular to given line is y = -x -2

The solution of the given linear equation in one variable 12 -3(2w + 1) = 7w -3(7 + w) is at w = 3.

According to the given question.

We have a linear equation in one variable.

12 -3(2w + 1) = 7w -3(7 + w)

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, the solution of the linear equation in one variable 12 -3(2w + 1) = 7w -3(7 + w) is given by

12 - 3(2w + 1) = 7w - 3(7 + w)

⇒ 12 - 6w -3 = 7w - 21 -3w                 (by distributive rule)

⇒ 9 - 6w = 4w - 21                          (subtracting the like terms)

⇒ 9 + 21 = 4w + 6w

⇒ 30 = 10w

⇒ 30/10 = w

⇒ w = 3

Hence, the solution of the given linear equation in one variable 12 -3(2w + 1) = 7w -3(7 + w) is at w = 3.

Geometric Transformation:

Images of triangles, quadrilaterals, pentagons, and other geometric shapes can undergo geometric transformations through the vertices in a Cartesian plane. Reflection, rotation, and translation are the three transformations; they only affect the geometric figure's location and not its size. Expansion and contraction are the two transformations that alter the geometric figure's size.

It is necessary to know the sort of transformation that took place given the points and their transformations.

1) We observe that point transformation A,B and C are transformed.

The transformation has the following form:

[tex](x,y)\rightarrow(x,-y)[/tex]

Every x-value remains constant, while every y-value flips from what it was.[tex](x,y)\rightarrow(x,-y)[/tex]

2)We observe that point transformations D, E, and F are contractions. Let's now identify the scalar that was applied to the transformation. We compute the product of the original point's coordinate and one of the transformation point's coordinates.

[tex]\frac{D^{'} _{y} }{D_{ y}} =\frac{4}{10} =\frac{2}{5}[/tex]

We multiply the coordinates of points E and F and check the results to make sure this is true.

For E:

[tex]\frac{2}{5} (5,10)=(2,4)\\Therefore,E^{'} =(2,4)[/tex]

For F:

[tex]\frac{2}{5} (10,-6)=(4,-2)\\Therefore,F^{'} =(4,-2)[/tex]

Therefore, The transformation has the following form:

[tex](x,y)\rightarrow\frac{2}{5}(x,y)[/tex]

3)We observe that point transformation G,H and I are transformed.

The transformation has the following form:

[tex](x,y)\rightarrow(-y,x)[/tex]

Every y-value flips from what it was to the opposite. The x and y values are reversed.[tex](x,y)\rightarrow(-y,x)[/tex]

We have been given two cases,

p: -3x + 8x - 5x = x

q: (3x)(5y) = 15xy

We have to need to isolate the variables:

p: -3x + 8x - 5x = x

⇒  (-3x - 5x) + 8x = x

⇒  -8x + 8x = x

⇒ x = 0

This is not always true, hence the statement is incorrect because this will hold true for only one value of x.

q: (3x)(5y) = 15xy

⇒ (3x)(5y) = 15xy

⇒ (3×5)(x×y) = 15xy

Step-by-step explanation:

The simplification by combining like terms of b -2(1 + c - b) is 3b -2c - 2.

According to the given question.

We have an expression b -2(1 + c - b).

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression b -2(1 + c - b).

Here b and 2b both are the like terms.

So, we add and subtract coeffcients of b to simplify the given expression.

Therefore, the simplification of the expression b -2( 1 + c - b) is given by

b - 2( 1+ c - b)

= b - 2 -2c + 2b

= 3b -2c - 2
