Given T(n) = T(⌊n/2⌋) + n, the corresponding runtime upper bound, lower bound and tight bound are given below:Tight bound: T(n) = O(n)Upper bound: T(n) = O(n)Lower bound: T(n) = Ω(n)Explanation:We know that, in Asymptotic analysis, the Big-O notation is used to represent the upper bound of the given function T(n). Similarly, the Ω-notation is used to represent the lower bound of the given function T(n).
Therefore, the corresponding runtime upper bound, lower bound and tight bound of the given function T(n) = T(⌊n/2⌋) + n are given as follows: Tight bound:To calculate the tight bound, we need to find both the upper and lower bounds, so let's start with the lower bound.
Lower bound: We can use the Ω-notation to find the lower bound of the function T(n). We know that T(n) = T(⌊n/2⌋) + n.Substituting n/2 in place of ⌊n/2⌋, we get T(n) = T(n/2) + n.
Now, we need to solve this function. To solve this, we need to expand T(n/2) again and again until it becomes a constant.The equation looks like:T(n) = T(n/2) + n= T(n/4) + n/2 + n= T(n/8) + n/4 + n/2 + n= T(n/16) + n/8 + n/4 + n/2 + n⋮T(1) + n/2 + n/4 + n/8 + .... + 1As n/2^k approaches 1, the sum approaches 2n - 1.The tight bound of the given function is: T(n) = Θ(n)Therefore, the tight bound of the given function T(n) is Θ(n).
Upper bound: We can use the Big-O notation to find the upper bound of the given function T(n). We know that T(n) = T(⌊n/2⌋) + n.Substituting n/2 in place of ⌊n/2⌋, we get T(n) = T(n/2) + n.To calculate the upper bound, let's assume that the solution of the function T(n) is O(n).
This implies that T(n) <= cn for all values of n >= k.Now, we need to prove that this assumption is true or false. For that, let's substitute the O(n) into the function T(n).T(n) = T(n/2) + n<= cn/2 + n<= cnSince n <= cn, the above equation can be written as: T(n) <= 2cnThis implies that the solution of the function T(n) is O(n). Therefore, the upper bound of the given function T(n) is O(n).
Therefore, the corresponding runtime upper bound, lower bound and tight bound of the given function T(n) = T(⌊n/2⌋) + n are given as follows:Tight bound: T(n) = Θ(n)Upper bound: T(n) = O(n)Lower bound: T(n) = Ω(n).Thus, the correct option is B.

Evaluate the limit. limh→π/2 1cos7h/h =
The limit of the expression limh→π/2 (1cos7h/h) can be evaluated using basic trigonometric properties and limit properties.
In summary, the limit of the expression limh→π/2 (1cos7h/h) is 0.
Now let's explain the steps to evaluate the limit. We can rewrite the expression as limh→π/2 (1/cos(7h))/h. Since the limit is in the form of 0/0, we can apply L'Hôpital's rule. Taking the derivative of the numerator and denominator separately, we get limh→π/2 (-7sin(7h))/1. Evaluating the limit again, we have (-7sin(7π/2))/1 = (-7)(-1)/1 = 7.
However, this is not the final answer. We need to consider that the original expression had a cosine term in the denominator. As h approaches π/2, the cosine function approaches 0, resulting in an undefined expression. Therefore, the limit of the expression is 0.
In conclusion, the limit of limh→π/2 (1cos7h/h) is 0, indicating that the expression approaches 0 as h approaches π/2.

What is performance? What measures will you be using to compare
system different models? help asap
Performance refers to the speed, capacity, and responsiveness of a system or device. It’s a measure of how well something is working or how efficiently it can complete a task.
When comparing different models of a system, there are several measures that can be used to determine which is best suited for a particular task.
One common measure of performance is processing speed, which is the amount of time it takes for a system to complete a specific task.
Another measure is memory capacity, which determines how much data can be stored and accessed by a system at one time.
Additionally, responsiveness measures how quickly a system can react to user inputs, such as clicks or taps.
When comparing different models, it’s important to consider all of these measures in order to determine which system is best suited for a particular task.
For example, if a task requires a lot of processing power, then a system with a faster processor would be more efficient. If a task involves a lot of data storage and retrieval, then a system with a larger memory capacity would be more suitable.
In addition to these measures, there are other factors to consider when comparing different models, such as battery life, screen resolution, and user interface design. Ultimately, the best system will depend on the specific needs of the user and the task at hand.

This turo curves \( y=x-x^{2} \) and \( y=x^{2}-1 \) is limit an area. What is the area?
The area of the bounded region is [(√5-1)/2] square units.
To find the area of the bounded region, we first need to find the points of intersection of the given curves:
We have the curves y=x-x² and y=x²-1
Equating them we get:
x-x²=x²-1
Rearranging:
x²+x-1=0
Solving the above quadratic equation we get:
x=(-1±√5)/2
So, the points of intersection are:
(-1+√5)/2 and (-1-√5)/2
Now, to find the area of the bounded region, we integrate the difference between the two curves between the points of intersection:
Area = ∫[(x²-1)-(x-x²)]dx
[limits: (-1-√5)/2 to (-1+√5)/2]
Area = ∫(2x²-x-1)dx

6. Let's assume the coordinates of point P are (x, y). According to the given condition, we have AP = (1/3)PB. Using the distance formula, we can write the equations:
√[(x - 0)^2 + (y - 5)^2] = (1/3)√[(x - 3)^2 + (y - 7)^2]
Simplifying the equation, we have:
(x^2 + (y - 5)^2) = (1/9)(x^2 - 6x + 9 + y^2 - 14y + 49)
Expanding and rearranging, we get:
8x - 2y + 50 = 0
Therefore, the equation of the locus of point P is 8x - 2y + 50 = 0.
This equation represents a straight line in the xy-plane, and it is the locus of all points P that satisfy the condition AP = (1/3)PB. The line passes through the fixed points A(0, 5) and B(3, 7), and any point P on this line will satisfy the given condition.
7. To determine if points D(-2, a), E(b, -8), and F(1, -2) are collinear, we can calculate the slopes between pairs of points. If the slopes are equal, the points are collinear.
The slope between D and E is given by (a - (-8))/(b - (-2)) = (a + 8)/(b + 2).
The slope between D and F is given by (a - (-2))/(b - 1) = (a + 2)/(b - 1).
For the points to be collinear, the slopes should be equal. Therefore, we have the equation:
(a + 8)/(b + 2) = (a + 2)/(b - 1)
Cross-multiplying, we get:
(a + 8)(b - 1) = (a + 2)(b + 2)
Expanding and simplifying, we obtain:
ab - a + 8b - 8 = ab + 2a + 2b + 4
Simplifying further, we have:
-3a + 6b - 12 = 0
Dividing both sides by -3, we get:
a - 2b + 4 = 0
Therefore, the points D(-2, a), E(b, -8), and F(1, -2) are collinear if they satisfy the equation a - 2b + 4 = 0. Any values of a and b that satisfy this equation will indicate that the points lie on the same line.

(c) Find the tangential and normal components of acceleration, a_T and a_N for t = 3.
(d) Find the curvature.
(a) To find the unit tangent vector T(t), we differentiate r(t) with respect to t and normalize the resulting vector. We have r'(t) = 4ti + j + tk. The magnitude of r'(t) is √(16t^2 + 1 + t^2), so the unit tangent vector T(t) is given by T(t) = (4ti + j + tk) / √(16t^2 + 1 + t^2). To find T(3), substitute t = 3 into the expression for T(t).
(b) The principal unit normal vector N(t) is obtained by differentiating T(t) with respect to t, dividing by its magnitude, and negating the result. N(t) = (-4t / √(16t^2 + 1 + t^2))i + (1 / √(16t^2 + 1 + t^2))j + (t / √(16t^2 + 1 + t^2))k. To find N(3), substitute t = 3 into the expression for N(t).
(c) To find the tangential and normal components of acceleration at t = 3, we differentiate T(t) and N(t) with respect to t, and then evaluate them at t = 3. The tangential component a_T(t) is given by a_T(t) = T'(t) · T(t), and the normal component a_N(t) is given by a_N(t) = T'(t) · N(t). Substitute t = 3 into these expressions to find a_T and a_N.

Abdulbaasit would like to buy a new car that costs $ 30000. The dealership offers to finance the car at 2.4% compounded monthly for 5 years with monthly payments. Instead, Abdulbaasit could get a 5-year loan from his bank at 5.4% compounded monthly and the dealer will reduce the selling price by $3000
when Abdulbaasit pays immediately in cash. Which is the best way to buy a car?
The best way for Abdulbaasit to buy the car would be to opt for the bank loan with the cash discount, as it offers a lower monthly payment and immediate cost savings.
To determine the best way to buy a car, we need to compare the financing options provided by the dealership and the bank. Let's evaluate both scenarios:
1. Financing at the dealership:
- Car price: $30,000
- Interest rate: 2.4% per year, compounded monthly
- Loan term: 5 years (60 months)
Using the provided interest rate and loan term, we can calculate the monthly payment using the formula for monthly loan payments:
Monthly interest rate = [tex](1 + 0.024)^(1/12)[/tex] - 1 = 0.001979
Loan amount = Car price = $30,000
Monthly payment = Loan amount * (Monthly interest rate) / (1 - (1 + Monthly interest rate)^(-Loan term))
Plugging in the values:
Monthly payment = $30,000 * 0.001979 /[tex](1 - (1 + 0.001979)^(-60)) =[/tex]$535.01 (approximately)
2. Bank loan with a cash discount:
- Car price with the $3,000 cash discount: $30,000 - $3,000 = $27,000
- Interest rate: 5.4% per year, compounded monthly
- Loan term: 5 years (60 months)
Using the provided interest rate and loan term, we can calculate the monthly payment using the same formula as above:
Monthly interest rate = (1 + 0.054)^(1/12) - 1 = 0.004373
Loan amount = Car price with cash discount = $27,000
Monthly payment = $27,000 * 0.004373 / (1 - (1 + 0.004373)^(-60)) = $514.10 (approximately)
Comparing the two options, we can see that the bank loan with the cash discount offers a lower monthly payment of approximately $514.10, compared to the dealership financing with a monthly payment of approximately $535.01. Additionally, with the bank loan option, Abdulbaasit can pay immediately in cash and save $3,000 on the car purchase.
Therefore, the best way for Abdulbaasit to buy the car would be to opt for the bank loan with the cash discount, as it offers a lower monthly payment and immediate cost savings.

Find the present value of an income stream with R(t)=60+0.4t,r=5 percent, and T=12. Round intermediate answers to eight decimal places and final answer to two decimal places.
The smaller i-value is -1/√198, and the larger i-value is also -1/√198.
To find two unit vectors orthogonal to both ⟨5, 9, 1⟩ and ⟨−1, 1, 0⟩, we can use the cross product of these vectors. The cross product of two vectors will give us a vector that is orthogonal to both of them.
Let's calculate the cross product:
⟨5, 9, 1⟩ × ⟨−1, 1, 0⟩
To compute the cross product, we can use the determinant method:
|i j k|
|5 9 1|
|-1 1 0|
= (9 * 0 - 1 * 1) i - (5 * 0 - 1 * 1) j + (5 * 1 - 9 * (-1)) k
= -1i - (-1)j + 14k
= -1i + j + 14k
Now, to obtain unit vectors, we divide the resulting vector by its magnitude:
Magnitude = √((-1)^2 + 1^2 + 14^2) = √(1 + 1 + 196) = √198
Dividing the vector by its magnitude, we get:
(-1/√198)i + (1/√198)j + (14/√198)k
Now we have two unit vectors orthogonal to both ⟨5, 9, 1⟩ and ⟨−1, 1, 0⟩:
First unit vector: (-1/√198)i + (1/√198)j + (14/√198)k
Second unit vector: (-1/√198)i + (1/√198)j + (14/√198)k
Therefore, the smaller i-value is -1/√198, and the larger i-value is also -1/√198.

Sloetch the graph of the functions

(b) f(x,y)=cosy
The graph of the function f(x, y) = 10 - 4x - 5y represents a plane with a negative slope intersecting the x-axis at 10/4 and the y-axis at 10. On the other hand, the graph of the function f(x, y) = cosy represents a periodic curve oscillating between -1 and 1 as y changes.
(a) The function f(x, y) = 10 - 4x - 5y represents a plane in three-dimensional space. The coefficients -4 and -5 determine the slope of the plane. Since both coefficients are negative, the plane has a negative slope. The constant term 10 determines the height at which the plane intersects the z-axis.
To sketch the graph, we can choose values for x and y to find corresponding values for z. For example, when x = 0 and y = 0, z = 10. This gives us a point on the plane. By connecting several such points, we can visualize the plane. The plane intersects the y-axis at the point (0, 2), and it intersects the x-axis at the point (2.5, 0).
(b) The function f(x, y) = cos y represents a curve in two-dimensional space. The cosine function has values ranging between -1 and 1. As y changes, the value of cos y oscillates between these extremes. The curve is periodic with a period of 2π, which means it repeats every 2π units of y.
To sketch the graph, we can choose values for y and calculate the corresponding values for f(x, y) using the cosine function. By plotting these points, we can observe the oscillatory behavior of the curve between -1 and 1. The graph has a wave-like shape that repeats itself as y increases or decreases.

o Yes, f is continuous on (-1, 1] and differentiable on (-1, 1) since polynomials are continuous and differentiable on R.
o Yes, it does not matter if f is continuous or differentiable; every function satisfies the Mean Value Theorem.
o If it satisfies the hypotheses, find all numbers c that satisfy the conclusion of the Mean Value Theorem. (Enter your answers as a comma-separated list. If it does not satisfy the hypotheses, enter DNE.) C= _____________
Hence, the answer is, Yes, f is continuous on (-1, 1] and differentiable on (-1, 1) since polynomials are continuous and differentiable on R. [tex]$C = 1$[/tex] satisfies the Mean Value Theorem.
The hypotheses of the Mean Value Theorem
The hypotheses of the Mean Value Theorem are as follows:
Continuous and differentiable on a closed interval [a, b].
The given function is f(x) = 3x² + 4x + 3, [-1, 1)
We are looking for a function that satisfies these hypotheses.
Polynomials are both continuous and differentiable over R, so f is continuous and differentiable over the interval [-1, 1].
Hence, the function satisfies the hypotheses of the Mean Value Theorem on the given interval.
Because we know that f(x) is both continuous and differentiable over the interval [-1, 1], we can use the Mean Value Theorem to find all numbers c that satisfy its conclusion.
The conclusion of the Mean Value Theorem is:
[tex]$$f'(c)=\frac{f(b)-f(a)}{b-a}$$[/tex]
Substituting the values into the above equation, we have:
[tex]$$f'(c)=\frac{f(1)-f(-1)}{1-(-1)}$$\\$$f'(c)=\frac{(3(1)^2+4(1)+3)-(3(-1)^2+4(-1)+3)}{2}$$[/tex]
After evaluating the above expression, we get,[tex]$$f'(c)=10$$[/tex]
Now we know that [tex]$f'(c)=10$[/tex], we can find the values of c that satisfy the above equation by equating [tex]$f'(c)$[/tex] to 10.
[tex]$$\begin{aligned}&f'(x)=6x+4\\&6x+4=10\end{aligned}$$[/tex]
Solving the above equation, we get,
[tex]$$6x = 6$$\\
$$x = 1$$[/tex]
Therefore, c = 1.
Hence, the answer is, Yes, f is continuous on (-1, 1] and differentiable on (-1, 1) since polynomials are continuous and differentiable on R. [tex]$C = 1$[/tex] satisfies the Mean Value Theorem.

if a typical somatic cell (somatic cell = typical body cell) has 64 chromosomes, how many chromosomes are expected in each gamete of that organism?
If a typical somatic cell has 64 chromosomes, each gamete of that organism is expected to have 32 chromosomes.
In sexually reproducing organisms, somatic cells are the cells that make up the body and contain a full set of chromosomes, which includes both sets of homologous chromosomes. Gametes, on the other hand, are the reproductive cells (sperm and egg) that contain half the number of chromosomes as somatic cells.
During the process of gamete formation, called meiosis, the number of chromosomes is halved. This reduction occurs in two stages: meiosis I and meiosis II. In meiosis I, the homologous chromosomes pair up and undergo crossing over, resulting in the shuffling of genetic material. Then, the homologous chromosomes separate, reducing the chromosome number by half. In meiosis II, similar to mitosis, the sister chromatids of each chromosome separate, resulting in the formation of four haploid daughter cells, which are the gametes.
Since a typical somatic cell has 64 chromosomes, the gametes produced through meiosis will have half that number, which is 32 chromosomes. These gametes, with 32 chromosomes, will combine during fertilization to restore the full set of chromosomes in the offspring, creating a diploid zygote with 64 chromosomes.

On an early foggy morning, pirates are loading stolen goods onto their ship at port. The dock of the port is located at the origin in the xy-plane. The x-axis is the beach.

What path does the Naval ship take to try to catch the pirates? The Naval ship always aims the boat directly at the pirates.
a.) Find the equation that models the pursuit path.
b.) Does the Naval ship ever catch the pirate? If so, when?
The distance between the pirate and naval ships goes to zero as t goes to infinity. So, we find the value of t that causes D to equal zero, and we obtain t = (a/2) × [(√(1 + (8/a2)) - 1]. Thus, the naval ship will catch the pirate after a certain amount of time has passed and they have traveled some distance.
a.) The equation that models the pursuit path of the naval ship isy
= (ax - 1) / a + (a / 2t) × ln[((t + 1)2 + a2) / a2].b.) Yes, the Naval ship will eventually catch the pirate. It is shown by evaluating the distance between the two ships as a function of time. Let's calculate this distance, denoted by D using the distance formula, D
= √(x2 + y2).First, let's find the velocity of the pirate ship using the distance formula. That is: V
= D/t
= √(a2 + [(ax)/(2t + 1)]2)/(2t + 1).Also, let's compute the velocity of the Naval ship using the distance formula. That is: V
= D/t
= √(a2 + [(ax)/(2t + 1)]2)/t.Using algebraic manipulation and some calculus, we obtain a relationship between the two velocities:1/t
= [1/2a] × ln[((t + 1)2 + a2) / a2].We can use this expression to substitute t in the equation we got from the velocity of the pirate ship. By doing so, we get:D
= (a/2) × [(1/a) × x + ln[(1/a2) × ((x2 + a2)/(t + 1)2)] + ln[a2]].Since we know that the Naval ship always points directly at the pirates, we can substitute x with the distance traveled by the pirate ship up the y-axis, which is simply a time multiplied by its velocity, t × (a/(2t + 1)). The equation then becomes:D
= a/2 × [(t/(2t + 1)) + ln[((2t + 1)2a2)/(a2(2t + 1)2 + (at)2)] + ln[a2]].The distance between the pirate and naval ships goes to zero as t goes to infinity. So, we find the value of t that causes D to equal zero, and we obtain t
= (a/2) × [(√(1 + (8/a2)) - 1]. Thus, the naval ship will catch the pirate after a certain amount of time has passed and they have traveled some distance.

d/ds ∫[-8stan(u^2+91)]du = -8stan(s^2+91) * 2s
The fundamental theorem of calculus states that if F(x) = ∫[a to x]f(t)dt, then d/dx F(x) = f(x). In this case, we have an integral with an upper limit of s^2+91, so we can apply this theorem.
We can rewrite the integral as F(s) = ∫[-8stan(u^2+91)]du. Now, to differentiate F(s) with respect to s, we apply the chain rule. The chain rule states that if F(x) = g(h(x)), then dF(x)/dx = g'(h(x)) * h'(x).
In our case, h(x) = s^2+91, and g(x) = -8tan(x). We differentiate g(x) with respect to x, giving us g'(x) = -8sec^2(x). Then, we differentiate h(x) with respect to s, which gives us h'(x) = 2s.
Applying the chain rule, we multiply g'(h(x)) and h'(x):
dF(s)/ds = -8tan(s^2+91) * 2s

Find the indefinite integral. sech² (3x) dx. Find the derivative of the function: y = tanh-¹ (sin 2x) Find the indefinite integral.
1. Indefinite Integral: To find the indefinite integral of sech² (3x) dx, let us proceed with the steps below: Let y = sech² (3x) dx We know that sech x = 1 / cosh x= 2 / [ e^x + e^(-x)] So, sech² x = (2 / [ e^x + e^(-x)])²= 4 / [e^(2x) + 2 + e^(-2x)]
Therefore, y = 4 / [e^(2(3x)) + 2 + e^(-2(3x))]dx
= 4 / [e^(6x) + 2 + e^(-6x)]dx
Let u = e^(6x)u²
= e^(12x)du
= 6e^(6x)dx
So, we can rewrite the expression as,
y = 4 / [(u² / u²) + 2(u / u²) + 1]
= 4 / [u² + 2u + 1 - u²]
= 4 / [(u + 1)² - 1]
Substituting the value of u back, we get the final expression as:
y = 4 / [(e^(6x) + 1)² - 1]
Now, using the formula of integration, we can write,
∫ sech² (3x) dx
= ∫ 4 / [(e^(6x) + 1)² - 1] dx
= 2 / tanh (3x + C),
where C is a constant of integration.
2. Derivative of the Function:
To find the derivative of y
= tanh-¹ (sin 2x),
let us first find the derivative of tanh y
=y
=tanh^-1 (sin 2x)We know that tanh y
= sin 2xWe know that sech² y dy/dx
=[tex]2 cos 2xdy/dx[/tex]
=[tex]2 cos 2x / sech² ydy/dx[/tex]
= [tex]2 cos 2x / (1 - tanh² y)dy/dx[/tex]
= [tex]2 cos 2x / [1 - sin² (tanh y)][/tex]
Now, we can use the identity, sin² a + cos² a
= 1 and
sin² a
= tanh² b, to get,
dy/dx
=[tex]2 cos 2x / [1 - tanh² (tanh^-1 (sin 2x))]dy/dx[/tex]
=[tex]2 cos 2x / [1 - sin² (2x)]dy/dx[/tex]
=[tex]2 cos 2x / cos² (2x)dy/dx[/tex]
[tex]= 2 / cos (2x)[/tex]
= 2 sec (2x)
Hence, the derivative of y
= tanh-¹ (sin 2x) is dy/dx
= 2 sec (2x).
3. Indefinite Integral:
To find the indefinite integral of, let us proceed with the steps below:
Let y = (sin³x)(cos x) dx
We know that sin³ x
= sin² x * sin xWe also know that sin
2x = 2 sin x cos xsin² x
= (1 - cos 2x) / 2
Therefore, sin³ x
= (1 - cos 2x) / 2 * sin x
So, y = (1 - cos 2x) / 2 * sin x * cos x dx
= 1/4 sin 2x - 1/2 ∫ cos² x sin x dx
Now, we can use the formula, d/dx [sin x]
= cos x, to get,
[tex]∫ cos² x sin x dx[/tex]
= - 1/2 ∫ sin x d(cos x)
[tex]=- 1/2 sin x cos x + 1/2 ∫ cos x d(sin x)= - 1/2 sin x cos x + 1/2 sin² x+ C[/tex]
= [tex]1/2 sin x (sin x - cos x) + C[/tex]
Now, substituting this back to y, we get the final expression as,∫ (sin³ x)(cos x) dx= 1/4 sin 2x - 1/2 ∫ cos² x sin x dx= 1/4 sin 2x - 1/2 [1/2 sin x (sin x - cos x)]+ C= 1/4 sin 2x - 1/4 sin x (sin x - cos x) + C, where C is a constant of integration.

We can see that the minterms of the function are 3, 7, 8, and 12.
We can also see that the control inputs for the 4:1 MUX are the complement of the two least significant input variables (C' and D').
Therefore, we can use the following circuit to implement the function:
In this circuit, the AND gates are used to implement the minterms of the function, and the OR gate is used to combine the minterms into the final output.
The 4:1 MUX selects between the output of the OR gate and the complement of the output based on the control inputs. Therefore, when C' = 0 and D' = 1, the MUX selects the output of the OR gate (which is 1), and when C' = 1 and D' = 0, the MUX selects the complement of the output (which is 0).
Overall, this circuit uses 10 gates (4 AND gates, 1 OR gate, and 5 gates in the 4:1 MUX).

4.2 A signal \( x(n) \) has a Fourier transform \[ X(\omega)=\frac{1}{1-a e^{-(j \omega)}} \] Determine the Fourier transform of the signal \( x(n) * x(-n) \) 4.3 Consider the FIR filter \[ y(n)=x(n)-
Fourier transform of the signal \(x(n) * x(-n)\) is given by \(\frac{1}{1 - 2a\cos(\omega) + a^2}\). This represents the frequency content of the convolved signal.
The Fourier transform of \(x(n) * x(-n)\) is obtained by squaring the magnitude of the Fourier transform of \(x(n)\).
To find the Fourier transform of the signal \(x(n) * x(-n)\), we can use the property that the convolution in the time domain corresponds to multiplication in the frequency domain. Therefore, the Fourier transform of \(x(n) * x(-n)\) is given by the squared magnitude of the Fourier transform of \(x(n)\).
Given that \(X(\omega) = \frac{1}{1 - ae^{-j\omega}}\) is the Fourier transform of \(x(n)\), we can obtain the Fourier transform of \(x(n) * x(-n)\) by squaring the magnitude of \(X(\omega)\):
\[
\left| X(\omega) \right|^2 = \left| \frac{1}{1 - ae^{-j\omega}} \right|^2
\]
Taking the squared magnitude of the complex function involves multiplying it by its complex conjugate:
\[
\left| X(\omega) \right|^2 = \frac{1}{(1 - ae^{-j\omega})(1 - ae^{j\omega})}
\]
Expanding the denominator and simplifying, we get:
\[
\left| X(\omega) \right|^2 = \frac{1}{1 - 2a\cos(\omega) + a^2}
\]
