Question \( \# 9 * \) : Consider the system whose open loop transfer function is such that: \[ G(s)=\frac{s+9}{(s-2)(s-3)(s+6)} \] a) Find a state space representation for the system using PFE. b) Des
A state space representation for the system can be obtained using the Partial Fraction Expansion (PFE) method. A state feedback controller can be designed to achieve 20.79% overshoot and a settling time of 4 seconds, with the third closed loop pole at s = -6. The range of the third closed loop pole should be chosen to approximate the system's response to that of a second-order system. The closed-loop transfer function of the system can be determined. The steady-state error due to a unit step input can be calculated.
(a) To obtain a state space representation using PFE, we express the open-loop transfer function G(s) in partial fraction form, and then determine the matrices A, B, C, and D for the state space representation.
(b) To design a state feedback controller for 20.79% overshoot and a settling time of 4 seconds, we can use pole placement techniques. By placing the third closed-loop pole at s = -6, we can calculate the desired feedback gain matrix K to achieve the desired response.
(c) The range of the third closed-loop pole can be determined by analyzing the desired system response characteristics. Generally, for a second-order system approximation, the damping ratio and natural frequency are crucial. By choosing appropriate values for the third closed-loop pole, we can approximate the system response to that of a second-order system.
(d) The closed-loop transfer function of the system can be obtained by combining the open-loop transfer function G(s) with the feedback controller transfer function.
(e) The steady-state error due to a unit step input can be calculated using the final value theorem. By evaluating the limit of the closed-loop transfer function as s approaches zero, the steady-state error can be determined.

discuss any two advantages of superposition theorem
compared to other circuit theorms
The advantages of the superposition theorem compared to other circuit theorems are its simplicity and modularity in circuit analysis, as well as its applicability to linear circuits.
Superposition theorem is a powerful tool in circuit analysis that allows us to simplify complex circuits and analyze them in a more systematic manner. When compared to other circuit theorems, such as Ohm's Law or Kirchhoff's laws, the superposition theorem offers several advantages. Here are two key advantages of the superposition theorem:
Simplicity and Modularity: One major advantage of the superposition theorem is its simplicity and modular approach to circuit analysis. The theorem states that in a linear circuit with multiple independent sources, the response (current or voltage) across any component can be determined by considering each source individually while the other sources are turned off. This approach allows us to break down complex circuits into simpler sub-circuits and analyze them independently. By solving these individual sub-circuits and then superposing the results, we can determine the overall response of the circuit. This modular nature of the superposition theorem simplifies the analysis process, making it easier to understand and apply.
Applicability to Linear Circuits: Another advantage of the superposition theorem is its applicability to linear circuits. The theorem holds true for circuits that follow the principles of linearity, which means that the circuit components (resistors, capacitors, inductors, etc.) behave proportionally to the applied voltage or current. Linearity is a fundamental characteristic of many practical circuits, making the superposition theorem widely applicable in real-world scenarios. This advantage distinguishes the superposition theorem from other circuit theorems that may have limitations or restrictions on their application, depending on the circuit's characteristics.
It's important to note that the superposition theorem has its limitations as well. It assumes linearity and works only with independent sources, neglecting any nonlinear or dependent sources present in the circuit. Additionally, the superposition theorem can become time-consuming when dealing with a large number of sources. Despite these limitations, the advantages of simplicity and applicability to linear circuits make the superposition theorem a valuable tool in circuit analysis.

Answer $1.44 a CrayonKamal made a replica of the Kaaba located in Mecca, Saudi Arabia. The dimensions of his replica are 24 cm long by 21 cm wide by 30 cm high. What is the surface area of the actual Kaaba in meters if the scale factor is 50
The surface area of the actual Kaaba is 1260 square meters.
To find the surface area of the actual Kaaba, we need to know the dimensions of the real Kaaba. Since we know the dimensions of Kamal's replica and the scale factor, we can use proportion to find the dimensions of the actual Kaaba.
Let x be the length of the actual Kaaba in meters.
Then we have:
x/24 = 50
x = 24 × 50 = 1200 cm = 12 meters
Similarly, the width and height of the actual Kaaba can be found using the same method:
Width of actual Kaaba = 21 cm × 50 = 1050 cm = 10.5 meters
Height of actual Kaaba = 30 cm × 50 = 1500 cm = 15 meters
Now we can find the surface area of the actual Kaaba. The surface area of a rectangular prism (which the Kaaba resembles) is given by:
Surface area = 2lw + 2lh + 2wh
Plugging in the values we found, we get:
Surface area = 2(1210.5) + 2(1215) + 2(10.5 × 15) = 1260 square meters

the different between two possitive nymbers is 48. the lesser number is 1/3 of the greater number. what are the two positive numbers
Let's call the greater number "x" and the lesser number "y". According to the problem, we know that:
x - y = 48 (since the difference between the two numbers is 48)
y = (1/3)x (since the lesser number is one third of the greater number)
Now we can substitute the second equation into the first equation:
x - (1/3)x = 48
Simplifying this equation, we get:
(2/3)x = 48
Multiplying both sides by 3/2, we get:
x = 72
Now that we know x, we can use the second equation to find y:
y = (1/3)x = (1/3)(72) = 24
So the two positive numbers are 72 and 24.

The equation of the translated and reflected graph is y = -√(x + 3) - 9.
option D.
What is the equation of the translated graph?
The equation of the translated graph is determined as follows;
Starting with the given graph of y = √x
a left shift of 3 units would result in the equation y = √(x + 3),
because the x-coordinate of each point on the graph is decreased by 3.
A vertical shift of 9 units would result in the equation y = -√(x + 3) - 9, because the y-coordinate of each point on the graph is increased by 9.
Reflecting the graph over the x-axis would result in the equation;
y = -√(x + 3) - 9

Fauvist artists extended the visual vocabulary of Post-Impressionism by making their primary subject matter Color
Fauvist artists, a group of early 20th-century painters, indeed extended the visual vocabulary of Post-Impressionism primarily through their innovative use of color. The Fauvist movement emerged in France in the early 1900s and was characterized by bold, vibrant colors and expressive brushwork.
Prior to the Fauvists, Post-Impressionist painters, such as Vincent van Gogh and Paul Cézanne, had already begun to break away from the naturalistic color palette of Impressionism. They explored new ways of using color to convey emotion and form, but it was the Fauvists who took this exploration to new levels.
Fauvist artists, including Henri Matisse, André Derain, and Raoul Dufy, embraced intense, non-naturalistic colors. They used bold, contrasting hues that were often unrelated to the actual appearance of their subjects. This departure from traditional color usage was a radical departure from the subdued, more subdued palettes of earlier movements.
By focusing on color as their primary subject matter, the Fauvists aimed to evoke powerful emotional responses from the viewers. They believed that color had the ability to express emotions and convey meaning on its own, without being limited to realistic representations of objects. Instead of relying on naturalistic color schemes, they used vivid and arbitrary colors to create a sense of energy and vitality.
The Fauvists also liberated color from its traditional role as a means to depict light and shadow. They applied colors freely and spontaneously, often using broad brushstrokes, without concern for accurate representation. This allowed them to create highly expressive and subjective interpretations of their subjects, whether they were landscapes, portraits, or still lifes.
In summary, Fauvist artists extended the visual vocabulary of Post-Impressionism primarily through their revolutionary use of color. By breaking away from the naturalistic color palette and embracing bold, vibrant hues, they explored the expressive potential of color itself, going beyond traditional notions of representation. Their approach opened up new avenues for artistic expression and paved the way for further experiments in color by future generations of artists.

Given the Cauchy-Euler equation, 4x2y′′+4xy′−y=0, find the roots of the auxiliary equation (listed in increasing order, if applicable) and and the solution given that the constants of integration are equal to one. y=
The roots of the auxiliary equation for the Cauchy-Euler equation \(4x^2y'' + 4xy' - y = 0\) are r = -1/2 and r = 1/2. The particular solution, given that the constants of integration are equal to one, is \(y(x) = 1/\sqrt{x} +\sqrt{x}\).
To find the roots of the auxiliary equation for the given Cauchy-Euler equation, we substitute \(y = x^r\) into the equation, where r is a constant. Let's solve it step by step.
The Cauchy-Euler equation is given as:
\(4x^2y'' + 4xy' - y = 0\)
Substituting \(y = x^r\) into the equation:
\(4x^2(r(r-1)x^{(r-2)}) + 4x(r)x^{(r-1) }- x^r = 0\)
Simplifying the equation:
\(4r(r-1)x^r + 4r x^r - x^r = 0\)
\(x^r\) is a common term, so we can factor it out:
\(x^r (4r(r-1) + 4r - 1) = 0\)
The equation will be true if either of the factors is equal to zero:
\(1) x^r = 0\)
This is not a valid solution since it leads to y = 0.
\(2) 4r(r-1) + 4r - 1 = 0\)
Expanding and simplifying the equation:
\(4r^2 - 4r + 4r - 1 = 0\\4r^2 - 1 = 0\)
Now, we solve this quadratic equation for r:
\(4r^2 - 1 = 0\\(2r)^2 - 1 = 0\\(2r + 1)(2r - 1) = 0\)
Setting each factor equal to zero:
2r + 1 = 0 or 2r - 1 = 0
For 2r + 1 = 0:
2r = -1
r = -1/2
For 2r - 1 = 0:
2r = 1
r = 1/2
Therefore, the roots of the auxiliary equation are r = -1/2 and r = 1/2.
Now, let's find the solution given that the constants of integration are equal to one.
For the root r = -1/2:
The solution is \(y_1(x) = x^r = x^{(-1/2)} = 1/\sqrt{x}\)
For the root r = 1/2:
The solution is \(y_2(x) = x^r = x^{(1/2)} = \sqrt{x}\)
Hence, the general solution to the Cauchy-Euler equation is:
\(y(x) = C_{1} 1/\sqrt{x} + C_{2} \sqrt{x}\)
Since the constants of integration are equal to one, the particular solution is: \(y(x) = 1/\sqrt{x} +\sqrt{x}\).
Please note that the solution is valid for x > 0.

a man has five pairs of socks, of which no two pairs are the same color. he randomly selects two socks from a drawer. what is the probability that he gets a matched pair? 118. bookshelf ord
The probability of the man getting a matched pair of socks when he randomly selects two socks from a drawer is 5/45, or approximately 0.11.
To calculate the probability of the man getting a matched pair of socks when he randomly selects two socks from a drawer, we need to consider the number of possible combinations of socks that result in a match and divide that by the total number of possible combinations of two socks.
The man has a total of 5 pairs of socks, or 10 socks, so there are 10 choose 2, or 45, possible combinations of two socks. Out of these, 5 of them result in a match, because there are 5 pairs of matching socks in the drawer.
Therefore, the probability of getting a matched pair of socks is 5/45, or approximately 0.11. This means that there is an 11% chance that the man will select a matched pair of socks if he randomly selects two socks from the drawer.
