The reliability of a simple electrical motor with three components (windings, armature, and housing) is :

0.9989.

To find the reliability of a simple electrical motor with three components (windings, armature, and housing), we need to multiply the reliabilities of each component. The given reliabilities are 0.9998, 0.9992, and 0.9999.

Multiply the reliabilities of the three components.
Reliability = Windings reliability * Armature reliability * Housing reliability
Reliability = 0.9998 * 0.9992 * 0.9999

Calculate the product.
Reliability ≈ 0.99889988

Round the answer to four decimal places.
Reliability ≈ 0.9989

So, the reliability of the motor is approximately 0.9989.

The equation of a line that has a slope of 3 and passes through the point (-1,6) is y=3x+9.

In mathematics, a line's slope or gradient is a number that specifies both its direction and its steepness. There is no obvious answer to why the letter m is used for slope, although its first use in English is in O'Brien (1844), who wrote the equation of a straight line .

The slope of a line is found by dividing the "vertical change" by the "horizontal change" between (any) two distinct places on the line. The ratio is sometimes stated as a quotient ("rise over run"), yielding the same value each time.

The equation of the line is,

y-y₁=m(x-x₁)

Where slope is m and the point in the line is (x₁, y₁)

Here m=3 and (x₁, y₁)=(-1, 6)

By substituting these values in the equation we get,

y-6=3(x-(-1))

y-6=3(x+1)

y-6=3x+3

y=3x+9

Hence, The equation of a line that has a slope of 3 and passes through the point (-1,6) is y=3x+9.

Since, the x-axis (equation y=0) does not intersect y=-7 at any point. The given pair of equations has no solution

Consider the pair of linear equations in two variables x and y.

a1x + b1y + c1 = 0

a2x + b2y + c2 = 0

Here a1, b1, c1, a2, b2, c2 are all real numbers.

Note that, a12 + b12 ≠ 0, a22 + b22 ≠ 0

1. If (a1/a2) ≠ (b1/b2), then there will be a unique solution. If we plot the graph, the lines will intersect. This type of equation is called a consistent pair of linear equations.

2. If (a1/a2) = (b1/b2) = (c1/c2), then there will be infinitely many solutions. The lines will coincide. This type of equation is called a dependent pair of linear equations in two variables

3. If (a1/a2) = (b1/b2) ≠ (c1/c2), then there will be no solution. If we plot the graph, the lines will be parallel. This type of equation is called an inconsistent pair of linear equations.

The number of comic books is an illustration of a linear function

She had 17 comic books already.

So, we have:

\(\mathbf{Base\ Amount = 17}\)

Her order of 65 books contains 8 comic books per collection.

So, we have:

\(\mathbf{Rate = 8}\)

\(\mathbf{Total = 65}\)

This is represented as:

\(\mathbf{Rate \times b + Base\ Amount =Total}\)

So, we have:

\(\mathbf{8\times b + 17 =65}\)

Rewrite as:

\(\mathbf{8b + 17 =65}\)

Subtract 17 from both sides

\(\mathbf{8b =48}\)

Divide both sides by 8

\(\mathbf{b =6}\)

Assume she has 97 books in her collection, then the equation would be represented as:

\(\mathbf{8b + 17 = 97}\)

Subtract 17 from both sides

\(\mathbf{8b = 80}\)

Divide both sides by 8

\(\mathbf{b = 10}\)

The values of b are 6 and 10.

The difference between 6 and 10 is 4

The equation whigh relates x and y points along the incline is: y = 2x - 3

We know that the general form of a slope - intercept form of equation of line is :

y = mx + c

m = slope

and c = y-intercept

We know that slope is nothing but angle of incline.

From figure we can observe that the line passes through points (3, 3) and (6, 9)

Using the formula of slope,

m = (9 - 3) / (6 - 3)

m =  6/3

m = 2

So the equation of line would be

y = 2x + c

As line passes though point (3, 3),

3 = 2(3) + c

3 = 6 + c

c = - 3

So, the equation that relates x and y for points along the incline is:

Relational databases are heavily based on the mathematical concept of: Set Theory. The correct option is (A).

Relational databases are based on the principles of set theory, which deals with sets of elements and their relationships with each other. In a relational database, data is organized into tables, with each table representing a set of related data.

The tables are then related to each other through the use of keys, which allow for the establishment of relationships between different sets of data. The principles of set theory also govern the use of operations such as union, intersection, and difference, which can be used to manipulate the data in the tables.

Therefore, the mathematical concept of set theory is a fundamental part of the design and use of relational databases.

The coordinates of the specified vertex after the given sequence of transformations is given by;

Q' = (3, -3).

In Mathematics, the translation of a geometric figure to the right simply means adding a digit to the value on the x-coordinate (x-axis) of the pre-image of a function while a geometric figure that is translated up simply means adding a digit to the value on the y-coordinate (y-axis) of the pre-image or parent function.

Mathematically, a horizontal translation to the right is modeled by this mathematical expression g(x) = f(x + N) while a vertical translation to the positive y-direction (upward) is modeled by this mathematical expression g(x) = f(x) + N.

Where:

By translating the coordinate Q (1, 3) two (2) units to the right, we have the following:

Coordinate Q (1, 3) → Coordinate Q' (1 + 2, 3) = Q (3, 3)

In Mathematics, a reflection across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would change from positive to negative. Therefore, a reflection over the x-axis is given by this transformation rule:

(x, y)      →       (x, -y)

Coordinate Q' (3, 3) → (3, -3).

The scale factor is 3/2 or 1 to 1.5

Step-by-step explanation:

Here, we want to find the scale factor of the first to the second

Since the triangles are similar, it follows that the corresponding sides are of equal ratio

So, we have the scale factor for the sides as;

6/4 or 9/6

= 3/2 or 1 to 1.5

A) 180 three-digit numbers can be formed from the digits 0, 1, 2, 3, 4, 5, and 6.

B) 75 of these numbers are odd.

C) 105 of these numbers are greater than 330.

A) There are 6 choices for the first digit, 6 choices for the second digit, and 5 choices for the third digit, so the total number of three-digit numbers that can be formed is 6*6*5 = 180.

B) To make number odd we need to fix last digit so the last digit have 3 option (1,3,5) first digit have 5 option and second digit have 5 option so total number is 5*5*3 = 75

C) The total number of numbers formed which are greater than 330 is obtained as shown below:

If the number starts with 3, the second place will be occupied by the digit 3, 4, 5, or 6 and the third place will be occupied by 1, 2, 3, 4, 5 and 6.

The number formed by the digit starts with 3 is  1*3*5 =15

If the digit starts with 4, 5 or 6, the number of digits formed are 3*6*5 =90

So total number greater than 330 is 90+15 =105

To find the area of the region interior to r = 9 + 7sin(θ) below the polar axis, we can integrate the function from the lower bound of θ to the upper bound of θ and take the absolute value of the integral.

To find the area of the region formed by two petals of r = 8sin(3θ), we can integrate the function over the appropriate range of θ and take the absolute value of the integral. To find dy/dx for the given parametric equations x = t^(1/3) and y = 3 - t, we differentiate y with respect to t and x with respect to t and then divide dy/dt by dx/dt.

To find the area of the region interior to r = 9 + 7sin(θ) below the polar axis, we need to evaluate the integral ∫[lower bound to upper bound] |1/2 * r^2 * dθ|. In this case, the lower bound and upper bound of θ will depend on the range of values where the function is below the polar axis. By integrating the expression, we can find the area of the region. To find the area of the region formed by two petals of r = 8sin(3θ), we need to evaluate the integral ∫[lower bound to upper bound] |1/2 * r^2 * dθ|.

The lower bound and upper bound of θ will depend on the range of values where the function forms the desired shape. By integrating the expression, we can calculate the area of the region. To find dy/dx for the parametric equations x = t^(1/3) and y = 3 - t, we differentiate both equations with respect to t. Taking the derivative of y with respect to t gives dy/dt = -1, and differentiating x with respect to t gives dx/dt = (1/3) * t^(-2/3). Finally, we can find dy/dx by dividing dy/dt by dx/dt, resulting in dy/dx = -3 * t^(2/3).
