Answers
The correct answer is under-damped. The expression "32+5+16" is not clear and does not provide sufficient information to determine the answer. Please provide additional details or clarify the question.
For the first question:
The system with input r(t) and output y(t) is described by the differential equation y(t) + y'(t) = x(t).
Explanation:
An over-damped system would have distinct real roots in the characteristic equation.
A critically damped system would have repeated real roots in the characteristic equation.
An undamped system would have imaginary roots in the characteristic equation.
An under-damped system has complex conjugate roots in the characteristic equation.
In this case, the characteristic equation of the system is s + 1 = 0, which has a root of s = -1. Since the root is a real number, it indicates an under-damped system.
For the second question:
The impulse response of the LTI system is h(t) = e^(-2t) + e^t.
The correct answer is:
ý''(t) + 3y'(t) + 2y(t) = x(t)
Explanation:
The linear differential equation with constant coefficients that represents the relation between the input r(t) and y(t) can be obtained by taking the derivative of the impulse response h(t) and plugging it into the general form of the equation.
The derivative of h(t) is h'(t) = -2e^(-2t) + e^t.
Using the general form of the equation, we have:
y''(t) + 3y'(t) + 2y(t) = x(t)
For the third question:
The LTI system with the impulse response h(t) = -e^(-2t) - e^t is described as stable and under-damped.
The correct answer is:
stable and under-damped
Explanation:
If the impulse response of an LTI system has only exponentially decaying terms, it is stable.
If the impulse response has complex conjugate terms, indicating complex poles, it is under-damped.
If the impulse response has real and distinct roots, it is over-damped.
If the impulse response has repeated roots, it is critically damped.
In this case, the impulse response has only exponentially decaying terms, indicating stability, and it has complex conjugate terms, indicating under-damping.
For the fourth question:
The given expression "32+5+16" is not clear and does not provide sufficient information to determine the answer. Please provide additional details or clarify the question.

The present worth of income from an investment that follows an arithmetic gradient is projected to be $475,000. The income in year one is expected to be $25,000. What is the gradient each year through year 6 at an interest rate of 10% per year?
I found this on another site:
475,000 = 25,000(P/A,10%,6) + G(P/G,10%,6)
475,000 = 25,000(4.3553) + G(9.6842)
9.6842G = 366,117.50
G = $37,805.65
Answers
Answer:
G = $37,805.65
Explanation:
I found this on another site:
475,000 = 25,000(P/A,10%,6) + G(P/G,10%,6)
475,000 = 25,000(4.3553) + G(9.6842)
9.6842G = 366,117.50
G = $37,805.65
The gradient each year through at an interest rate of 10% per year is $37,805.65.
What is investment?Investment refers to the money spend on the acquiring the assets and also to build up the capital for the businessmen and wealth for the individual. It involves saving of the money.
Investment is the collection of the money from other primary source of the income. It also includes profit gains from the investment over a specific period of time.
According to the question, projected arithmetic gradient is $475,000 and estimated income for one year is $25,000.
Thus, the gradient for each year is calculated as follows:-
475,000 = 25,000(P/A,10%,6) + G(P/G,10%,6)
475,000 = 25,000(4.3553) + G(9.6842)
9.6842G = 366,117.50
Gradient = $37,805.65
Therefore, it can be concluded that gradient each year through at an interest rate of 10% per year is $37,805.65.

2. L = {x over {0,1} | x as a binary number divisible by 3}
3. L = {x over {a, b} | x contains both ‘aba’ and ‘bab’ as a substring}
Answers
DFA for given languages are given as:
1. DFA start with , intermediate, and accepting states to ensure the third last element is 1.
2. DFA starts with three states representing remainders, transitioning based on input bits to check if the final state is 0 (divisible by 3).
3. DFA using states to track the occurrence of substrings 'aba' and 'bab' and reach the final state if both are found.
1. For language L = {x over {0, 1} | 3rd last element must be 1}, the DFA can be designed by considering three states: start state, intermediate state, and accepting state. The DFA will transition to the intermediate state after reading the first two elements, and then transition to the accepting state after reading the remaining elements, ensuring that the third last element is 1.
2. For language L = {x over {0,1} | x as a binary number divisible by 3}, the DFA can be designed with three states representing the remainders of the binary number when divided by 3: state 0 for a number divisible by 3, state 1 for a number with a remainder of 1, and state 2 for a number with a remainder of 2. The DFA will transition based on the input bits and maintain the current remainder until the end of the input. If the final state is 0, the input is divisible by 3.
3. For language L = {x over {a, b} | x contains both ‘aba’ and ‘bab’ as a substring}, the DFA can be designed using a combination of states to track the occurrence of substrings 'aba' and 'bab'. The DFA will transition accordingly when it encounters the input symbols 'a' or 'b' and move to the next state. The final state will be reached if both substrings 'aba' and 'bab' are found.

Calculate the absolute value of thetrue strain that the strip undergoes in this operation. Determine the average true stress of the strip in theroll gap. Calculate the roll force. Calculate the horsepower required.
Answers
Answer:
13.9357 horse power
Explanation:
Annealed copper
Given :
Width, b = 9 inches
Thickness, \($h_0=2.2$\) inches
K= 90,000 Psi
μ = 0.2, R = 14 inches, N = 150 rpm
For the maximum possible draft in one pass,
\($\Delta h = H_0-h_f=\mu^2R$\)
\($=0.2^2 \times 14 = 0.56$\) inches
\($h_f = 2.2 - 0.56$\)
= 1.64 inches
Roll strip contact length (L) = \($\sqrt{R(h_0-h_f)}$\)
\($=\sqrt{14 \times 0.56}$\)
= 2.8 inches
Absolute value of true strain, \($\epsilon_T$\)
\($\epsilon_T=\ln \left(\frac{2.2}{1.64}\right) = 0.2937$\)
Average true stress, \($\overline{\gamma}=\frac{K\sum_f}{1+n}= 31305.56$\) Psi
Roll force, \($L \times b \times \overline{\gamma} = 2.8 \times 9 \times 31305.56$\)
= 788,900 lb
For SI units,
Power = \($\frac{2 \pi FLN}{60}$\)
\($=\frac{2 \pi 788900\times 2.8\times 150}{60\times 44.25\times 12}$\)

Enum are is a type of data type used to define programmers with their own datatype. 1. 2. 3. The SFSU University Police Department has been sending out live updates when there are incidents happening on campus. Would you use Deep or Shallow copies to implement this communication? Please explain in detail.
Answers
The answers to the methods of deep copies, Enum and communication implementation is given below.
What are methods for deep copies?When copying an object in Java, there are two options that should be taken into account: shallow copy and deep copy. When we merely copy field values and the copy depends on the original object, we utilise a shallow copy. same, references to any fields that contain objects are transferred but not the actual objects themselves. Make sure that all three objects are thoroughly copied in order to prevent the copy from depending on an earlier object that may change in the future. When we attempt to generate an object duplicate, all fields from the original object are precisely reproduced in the deep copy. and if it contains fields that are objects, a copy of those fields is made using the clone function (). The original and duplicated objects refer to distinct objects when you conduct a deep copy on an object that contains an object, and if you make changes to the data, the copied objects do not reflect those changes in the original objects.
What is Enum?Enum is a sort of data type that programmers can use to construct their own data types —
A particular data type called an enum allows variables to be configured using predefined constants. and the variable should equal one of the predefined values for it. For instance, the compass's orientation (values of NORTH, SOUTH, EAST, and WEST) and the day of the weekAdditionally, the names of the fields on an enum type are all capitalised because they are constant. and the "enum" keyword can be used to define an enum type in java programming. For instance, we can provide the public enum type for the days of the week. Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday are the days.
Shall we use Deep or Shallow copies to implement this communication?The SFSU University Police Department has begun sending out live updates when there are occurrences occurring on campus. Because all field values and copies in shallow copies are dependent on the original objects, this communication can be implemented using this manner.

Pegs A and B are restricted to move in the elliptical slots due to the motion of the slotted link.
Part A
If the link moves with a constant speed of 10 m/s , determine the magnitude of the velocity of peg A when x = 1. 2 m.
Part B
Determine the magnitude of the acceleration of peg A when x = 1. 2 m
Answers
For Part A, the velocity of peg A when x = 1.2 m can be calculated using the equation v = s/t, where s is the distance traveled and t is the time taken. Since the link is moving at a constant speed of 10 m/s, the time taken to travel 1.2 m is 1.2/10 = 0.12 s.
Therefore, the velocity of peg A when x = 1.2 m is v = 10/0.12 = 83.33 m/s.
For Part B, the acceleration of peg A when x = 1.2 m can be calculated using the equation a = (v2 - v1)/t, where v2 and v1 are the velocities of the peg at the two different points and t is the time taken to travel between them. Since the link is moving at a constant speed of 10 m/s, the time taken to travel 1.2 m is 0.12 s.
Therefore, the acceleration of peg A when x = 1.2 m is a = (83.332 - 102)/0.12 = -833.33 m/s2.

(a) (6 points) Find the integer a in {0, 1,..., 26} such that a = -15 (mod 27). Explain. (b) (6 points) Which positive integers less than 12 are relatively prime to 12?
Answers
a. a = 12 is the solution to the given congruence relation. b. the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.
(a) The main answer: The integer a that satisfies a ≡ -15 (mod 27) is 12.
To find the value of a, we need to consider the congruence relation a ≡ -15 (mod 27). This means that a and -15 have the same remainder when divided by 27.
To determine the value of a, we can add multiples of 27 to -15 until we find a number that falls within the range of {0, 1,..., 26}. By adding 27 to -15, we get 12. Therefore, a = 12 is the solution to the given congruence relation.
(b) The main answer: The positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.
Supporting explanation: Two integers are relatively prime if their greatest common divisor (GCD) is 1. In this case, we are looking for positive integers that have no common factors with 12 other than 1.
To determine which numbers satisfy this condition, we can examine each positive integer less than 12 and calculate its GCD with 12.
For 1, the GCD(1, 12) = 1, which means it is relatively prime to 12.
For 2, the GCD(2, 12) = 2, so it is not relatively prime to 12.
For 3, the GCD(3, 12) = 3, so it is not relatively prime to 12.
For 4, the GCD(4, 12) = 4, so it is not relatively prime to 12.
For 5, the GCD(5, 12) = 1, which means it is relatively prime to 12.
For 6, the GCD(6, 12) = 6, so it is not relatively prime to 12.
For 7, the GCD(7, 12) = 1, which means it is relatively prime to 12.
For 8, the GCD(8, 12) = 4, so it is not relatively prime to 12.
For 9, the GCD(9, 12) = 3, so it is not relatively prime to 12.
For 10, the GCD(10, 12) = 2, so it is not relatively prime to 12.
For 11, the GCD(11, 12) = 1, which means it is relatively prime to 12.
Therefore, the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

Technician A says the master cylinder changes the driver's mechanical force on the pedal to
hydraulic pressure.
Technician B says this hydraulic pressure is changed back to mechanical force at the wheel brakes.
Who is correct?
Answers
Answer:
Explanation:
Both technicians are correct, but they are describing different parts of the brake system.
Technician A is describing the function of the master cylinder, which converts the mechanical force exerted on the brake pedal by the driver into hydraulic pressure. The master cylinder contains a piston that moves in response to the force applied to the brake pedal, which in turn pressurizes the brake fluid in the hydraulic lines.
Technician B is describing the function of the wheel brakes themselves. The hydraulic pressure generated by the master cylinder is transmitted through the brake lines to the calipers or wheel cylinders at each wheel. These components convert the hydraulic pressure back into mechanical force, which applies the brake pads or shoes to the rotors or drums and slows down the vehicle.
Therefore, both technicians are correct in their descriptions of the brake system, but they are referring to different components.
