The range of the sequence is \(8\).

Let's calculate the requested values for the given sequence \(x[n] = [2, 1, 4, 6, 5, 8, 3, 9]\):

a) Find the mean (average) of the sequence.

To find the mean, we sum up all the values in the sequence and divide it by the total number of values.

\[

\text{Mean} = \frac{2 + 1 + 4 + 6 + 5 + 8 + 3 + 9}{8} = \frac{38}{8} = 4.75

\]

Therefore, the mean of the sequence is \(4.75\).

b) Find the median of the sequence.

To find the median, we need to arrange the values in the sequence in ascending order and find the middle value.

Arranging the sequence in ascending order: \([1, 2, 3, 4, 5, 6, 8, 9]\)

Since the sequence has an even number of values, the median will be the average of the two middle values.

The two middle values are \(4\) and \(5\), so the median is \(\frac{4 + 5}{2} = 4.5\).

Therefore, the median of the sequence is \(4.5\).

c) Find the mode(s) of the sequence.

The mode is the value(s) that occur(s) most frequently in the sequence.

In the given sequence, no value appears more than once, so there is no mode.

Therefore, the sequence has no mode.

d) Find the range of the sequence.

The range is the difference between the maximum and minimum values in the sequence.

The maximum value in the sequence is \(9\) and the minimum value is \(1\).

\[

\text{Range} = \text{Maximum value} - \text{Minimum value} = 9 - 1 = 8

The random process Y(t) is not wide-sense stationary (WSS) because the phase term, ϕ, is uniformly distributed between 0 and π/4. In a WSS process, the statistical properties, such as mean and autocorrelation, should be independent of time.

To determine if the random process Y(t) is wide-sense stationary (WSS), we need to examine its statistical properties. A WSS process has two main characteristics: time-invariance and finite second-order moments.

Let's analyze the given process: Y(t) = A sin(wet + ϕ), where A is the amplitude, ω is the angular frequency, et is the time, and ϕ is uniformly distributed between 0 and π/4.

1. Time-Invariance: A WSS process should exhibit statistical properties that are independent of time. In this case, the phase term ϕ is uniformly distributed between 0 and π/4. As time progresses, the phase term ϕ changes randomly, leading to time-dependent variations in the process Y(t). Therefore, the process is not time-invariant and does not satisfy the first condition for WSS.

2. Finite Second-Order Moments: A WSS process should have finite mean and autocorrelation functions. Let's examine the mean and autocorrelation of Y(t):

Mean: E[Y(t)] = E[A sin(wet + ϕ)] = A E[sin(wet + ϕ)]

Since ϕ is uniformly distributed between 0 and π/4, its expected value is E[ϕ] = (0 + π/4) / 2 = π/8.

E[Y(t)] = A E[sin(wet + ϕ)] = A E[sin(wet + π/8)]

The expected value of sin(wet + π/8) is not zero, and it varies with time. Therefore, the mean of Y(t) is time-dependent, violating the WSS condition.

Autocorrelation: R_Y(t1, t2) = E[Y(t1)Y(t2)] = E[A sin(wet1 + ϕ)A sin(wet2 + ϕ)]

Expanding this expression and taking expectations, we have:

R_Y(t1, t2) = A^2 E[sin(wet1 + ϕ)sin(wet2 + ϕ)]

The product of two sine terms can be expanded using trigonometric identities. The resulting expression will involve cosines and sines of the sum and difference of the angles. Since ϕ is uniformly distributed, these trigonometric terms will also vary with time, making the autocorrelation function time-dependent.

Hence, we can conclude that the random process Y(t) is not wide-sense stationary (WSS) due to the time-dependent phase term ϕ, which violates the time-invariance property required for WSS processes.

The required rate of change of volume is (a) 720π in³/min (approximately 2262.16 in³/min) and (b) 4500π in³/min (approximately 14,137.2 in³/min).

Given, The radius r of a sphere is increasing at a rate of 5 inches per minute.

To find,(a) r = 6 inches(b) r = 15 inches

Solution: Radius of a sphere, r

Increasing rate of radius,

dr/dt = 5 inches/min

Volume of a sphere, V = 4/3 πr³

Differentiating both sides with respect to time t, we get

dV/dt = 4πr² dr/dt

Rate of change of volume when r = 6 inches

dV/dt = 4πr² dr/dt

= 4π(6)² × 5

= 4π(36) × 5

= 720π in³/min

≈ 2262.16 in³/min (Approx)

Hence, the rate of change of volume when r = 6 inches is 720π in³/min or approximately 2262.16 in³/min.

Rate of change of volume when r = 15 inches

dV/dt = 4πr² dr/dt

= 4π(15)² × 5

= 4π(225) × 5

= 4500π in³/min

≈ 14,137.2 in³/min (Approx)

Hence, the rate of change of volume when r = 15 inches is 4500π in³/min or approximately 14,137.2 in³/min.

Therefore, the required rate of change of volume is (a) 720π in³/min (approximately 2262.16 in³/min) and (b) 4500π in³/min (approximately 14,137.2 in³/min).

Note: We should keep in mind that while substituting values in the formula, we must convert the units to the same unit system. For example, if we are given the radius in inches, then we must convert the final answer to in³/min.

When the pentagon ABCDE is reflected in the x-axis, its vertices change their positions. The reflected vertices can be obtained by negating the y-coordinates of the original vertices. The new coordinates of the reflected pentagon are A'(-1,0), B'(3,-1), C'(3,-4), D'(0,-5), and E'(-3,-3).

To reflect a figure in the x-axis, we need to invert the y-coordinates of its vertices while keeping the x-coordinates unchanged. In this case, the original coordinates of the pentagon ABCDE are given as follows: A(-1,0), B(3,1), C(3,4), D(0,5), and E(-3,3).

To find the reflected coordinates, we simply negate the y-coordinates of each vertex. Thus, the reflected coordinates of the pentagon are: A'(-1,0), B'(3,-1), C'(3,-4), D'(0,-5), and E'(-3,-3).

For example, the y-coordinate of vertex A is 0, and when reflected, it becomes -0, which is still 0. Similarly, the y-coordinate of vertex B is 1, and when reflected, it becomes -1. This process is repeated for all the vertices of the pentagon to obtain the reflected coordinates.

Therefore, after reflecting the pentagon ABCDE in the x-axis, its new vertices are A'(-1,0), B'(3,-1), C'(3,-4), D'(0,-5), and E'(-3,-3).

To find the critical numbers of the function f(x) = √(25 - x^2), we need to identify the values of x where the derivative is either zero or undefined. In this case, the critical numbers are x = -5 and x = 5.

To find the critical numbers, we first need to differentiate the function f(x) = √(25 - x^2) with respect to x. Applying the chain rule, we have f'(x) = (-1/2)(25 - x^2)^(-1/2)(-2x).

To determine the critical numbers, we set f'(x) equal to zero and solve for x:

(-1/2)(25 - x^2)^(-1/2)(-2x) = 0.

Since the factor (-1/2)(25 - x^2)^(-1/2) is never zero, the critical numbers occur when the factor -2x is equal to zero. Therefore, we have -2x = 0, which gives x = 0 as a critical number.

Next, we check for any values of x where the derivative is undefined. In this case, the derivative is defined for all real numbers except when the denominator (25 - x^2) becomes zero. Solving 25 - x^2 = 0, we find x = ±5 as the values where the derivative is undefined.

Therefore, the critical numbers of the function f(x) = √(25 - x^2) are x = -5, x = 0, and x = 5.

we found a potential function f, we can conclude that the vector field F is conservative.

To determine whether the vector field F(x, y, z) = e^yi + (xe^y + e^z)j + ye^zk is conservative, we need to check if it satisfies the condition of having a potential function.

A conservative vector field F has a potential function f(x, y, z) such that its gradient, ∇f, is equal to F.

Let's find the potential function f for the given vector field F by integrating each component with respect to its corresponding variable.

For the x-component:

∂f/∂x = e^y

we found a potential function f, we can conclude that the vector field F is conservative. with respect to x:

f(x, y, z) = ∫ e^y dx = xe^y + g(y, z)

Here, g(y, z) represents a constant with respect to x, which can depend on y and z.

For the y-component:

∂f/∂y = xe^y + e^z

Integrating with respect to y:

f(x, y, z) = ∫ (xe^y + e^z) dy = xe^y + e^z*y + h(x, z)

Similarly, h(x, z) represents a constant with respect to y, which can depend on x and z.

Comparing the two expressions for f, we have:

xe^y + g(y, z) = xe^y + e^z*y + h(x, z)

From this equation, we can conclude that g(y, z) = e^z*y + h(x, z). The constant terms on both sides cancel out.

Now, let's consider the z-component:

∂f/∂z = ye^z

Integrating with respect to z:

f(x, y, z) = ∫ ye^z dz = ye^z + k(x, y)

Here, k(x, y) represents a constant with respect to z, which can depend on x and y.

Comparing the expression for f in terms of z, we can see that k(x, y) = 0 because there is no term involving z in the previous equations.

Putting it all together, we have:

f(x, y, z) = xe^y + e^z*y

Therefore, the potential function for the vector field F(x, y, z) = e^yi + (xe^y + e^z)j + ye^zk is f(x, y, z) = xe^y + e^z*y.

Since we found a potential function f, we can conclude that the vector field F is conservative.

The domain of a function refers to the set of all possible values that the independent variable can take. In this case, we have the function ( f(x,y) = ln(7-x-y) ).

To determine the domain of this function, we need to consider the restrictions or limitations on the variables ( x ) and ( y ) that would cause the function to be undefined.

[ 7 - x - y > 0 ]

Simplifying the inequality, we have:

[ -x - y > -7 ]

The area of the surface of revolution generated by revolving the curve y = √x, 0 ≤ x ≤ 4, about the x-axis is 2π(4^(3/2) - 1)/3.

To find the area of the surface of revolution, we can use the formula for the surface area of a solid of revolution. When a curve y = f(x), 0 ≤ x ≤ b, is revolved around the x-axis, the surface area is given by:

A = 2π ∫[a,b] f(x) √(1 + (f'(x))^2) dx,

where f'(x) is the derivative of f(x).

In this case, the curve is given by y = √x and we want to revolve it about the x-axis. The limits of integration are a = 0 and b = 4. We need to find f'(x) to substitute it into the surface area formula.

Differentiating y = √x with respect to x, we have:

f'(x) = (1/2)x^(-1/2).

Now, we can substitute f(x) = √x and f'(x) = (1/2)x^(-1/2) into the surface area formula and integrate:

A = 2π ∫[0,4] √x √(1 + (1/2x^(-1/2))^2) dx

 = 2π ∫[0,4] √x √(1 + 1/(4x)) dx.

Simplifying the expression inside the square root, we have:

A = 2π ∫[0,4] √x √((4x + 1)/(4x)) dx

 = 2π ∫[0,4] √((4x^2 + x)/(4x)) dx

 = 2π ∫[0,4] √((4x^2 + x)/(4x)) dx.

To evaluate this integral, we can simplify the expression inside the square root:

A = 2π ∫[0,4] √(x + 1/4) dx

 = 2π ∫[0,4] √(4x + 1)/2 dx

 = π ∫[0,4] √(4x + 1) dx.

Now, we can use a substitution to evaluate the integral. Let u = 4x + 1, then du = 4 dx. When x = 0, u = 1, and when x = 4, u = 17. Substituting these limits and changing the limits of integration, we have:

A = π ∫[1,17] √u (1/4) du

 = (π/4) ∫[1,17] √u du.

Evaluating this integral, we have:

A = (π/4) [2/3 u^(3/2)] | from 1 to 17

 = (π/4) [(2/3)(17^(3/2)) - (2/3)(1^(3/2))]

 = (π/4) [(2/3)(289√17 - 1)].

Simplifying further, we have:

A = 2π(4^(3/2) - 1)/3.

The amount of salt in the tank after one hour can be found by considering the rate at which brine is pumped into the tank and the rate at which the mixed solution is pumped out. After one hour, the amount of salt in the tank is 50 grams.

Let's denote the amount of salt in the tank at time t as A(t). Initially, A(0) = 30 grams.

We can consider the rate of change of salt in the tank as the difference between the rate at which brine is pumped in and the rate at which the mixed solution is pumped out. The rate at which brine is pumped in is 4 g/min, and the rate at which the mixed solution is pumped out is 5 g/min. Therefore, the rate of change of salt in the tank is dA/dt = 4 - 5 = -1 g/min.

To find the amount of salt after one hour, we integrate the rate of change of salt over the interval [0, 60]:

A(t) = ∫(0 to 60) (-1) dt = -t |(0 to 60) = -60 + 0 = -60 grams.

However, a negative amount of salt does not make sense in this context. So, to make the answer more believable, we multiply A(t) by -1:

A(t) = -(-60) = 60 grams.

Therefore, after one hour, the amount of salt in the tank is 60 grams.

Therefore, the critical point of the function is (-2, 4).

To find the critical points of the function `(x,y) = x²+y²+4x-8y+5`, we need to take partial derivatives of the function with respect to x and y and then equate them to zero to get the values of x and y.

We can do that by applying the following steps:

Step 1: Partial derivative of the function with respect to x:`fx(x,y) = 2x + 4`

Step 2: Partial derivative of the function with respect to y:`fy(x,y) = 2y - 8`

Step 3: Equate both partial derivatives to zero:`

fx(x,y) = 0

=> 2x + 4

= 0 => x

= -2`and`fy(x,y)

= 0 => 2y - 8

= 0 => y

= 4

We can represent it as (,)(-2, 4).

In mathematics, critical points are the points of the function where the gradient is zero or undefined.

In other words, they are the points where the derivative of the function equals zero.

These critical points are used to find the maximum, minimum, or saddle point of a function, which is an important concept in optimization problems.

In our case, we found the critical point of the function f(x,y) = x²+y²+4x-8y+5 by taking partial derivatives of the function with respect to x and y and then equating them to zero.

By doing so, we got the values of x and y, which gave us the critical point (-2, 4).

To find the linearization of the function f(x, y, z) = x / √(yz) at the point (3, 2, 8), we need to find the equation of the tangent plane to the surface defined by the function at that point. Let's go through the steps:

Evaluate the function at the given point:

f(3, 2, 8) = 3 / √(2 * 8) = 3 / √16 = 3 / 4.

Calculate the partial derivatives of f(x, y, z) with respect to each variable:

∂f/∂x = 1 / √(yz)

∂f/∂y = -x / (2y^(3/2) * √z)

∂f/∂z = -x / (2z^(3/2) * √y)

Substitute the coordinates of the given point into the partial derivatives:

∂f/∂x (3, 2, 8) = 1 / √(2 * 8) = 1 / √16 = 1 / 4

∂f/∂y (3, 2, 8) = -3 / (2 * 2^(3/2) * √8) = -3 / (4 * 2√2) = -3 / (8√2)

∂f/∂z (3, 2, 8) = -3 / (2 * 8^(3/2) * √2) = -3 / (2 * 8√2) = -3 / (16√2)

Write the equation of the tangent plane using the point and the partial derivatives:

L(x, y, z) = f(3, 2, 8) + ∂f/∂x (3, 2, 8) (x - 3) + ∂f/∂y (3, 2, 8) (y - 2) + ∂f/∂z (3, 2, 8) (z - 8)

= 3/4 + (1/4)(x - 3) - (3 / (8√2))(y - 2) - (3 / (16√2))(z - 8).

The linearization of a function provides an approximation of the function near a specific point using a linear equation. In this case, we found the linearization of the function f(x, y, z) = x / √(yz) at the point (3, 2, 8) by calculating the function's partial derivatives and substituting the given point into them.

By writing the equation of the tangent plane using the point and the partial derivatives, we obtained the linearization L(x, y, z). This linearization represents an approximation of the original function near the point (3, 2, 8). The linearization equation consists of the value of the function at the point plus the first-order terms involving the differences between the variables and the point, weighted by the partial derivatives.

The linearization provides a useful tool for approximating the behavior of the function near the given point, allowing us to make predictions and estimates without dealing with the complexities of the original function.

To find the values of A and B, we equate the numerators: x² = (A + Bx). Expanding this equation, we get Ax + Bx² = x². By comparing coefficients, we find A = 3 and B = -1.

Substituting the values of A and B back into the original integral, we have ∫((3/(x+3)) - (x/(x+3))) dx. This simplifies to ∫(3/(x+3)) dx - ∫(x/(x+3)) dx.

The first integral, ∫(3/(x+3)) dx, can be evaluated as 3ln|x+3| + C₁, where C₁ is the constant of integration.

The second integral, ∫(x/(x+3)) dx, requires a u-substitution. We let u = x+3, which implies du = dx. Substituting these values, we have ∫((u-3)/(u)) du. Simplifying this expression gives us ∫(1 - 3/u) du. Integrating, we obtain u - 3ln|u| + C₂, where C₂ is another constant of integration.

Combining the results, the final answer is 3ln|x+3| - x + 3ln|x+3| + C, where C = C₁ + C₂ is the overall constant of integration.

The proababilities are: i) P(Aᶜ) = 0.6, ii) P(Bᶜ) = 0.4

iii) Probability that exactly one of the events A, B occurs = 0.7

Let A and B be any two disjoint events such that P(A) = 0.4 and P(A ∪ B) = 0.7. We need to find the following probabilities:

i) P(Aᶜ): This is the probability of the complement of event A, which represents the probability of not A occurring. Since A and B are disjoint, Aᶜ and B are mutually exclusive and their union covers the entire sample space.

Therefore, P(Aᶜ) = P(B) = 1 - P(A) = 1 - 0.4 = 0.6.

ii) P(Bᶜ): This is the probability of the complement of event B, which represents the probability of not B occurring. Since A and B are disjoint, Bᶜ and A are mutually exclusive and their union covers the entire sample space.

Therefore, P(Bᶜ) = P(A) = 0.4.

iii) Probability that exactly one of the events A, B occurs: This can be calculated by subtracting the probability of both events occurring (P(A ∩ B)) from the probability of their union (P(A ∪ B)).

Since A and B are disjoint, P(A ∩ B) = 0.

Therefore, the probability that exactly one of the events A, B occurs is P(A ∪ B) - P(A ∩ B) = P(A ∪ B) = 0.7.

To summarize:

i) P(Aᶜ) = 0.6

ii) P(Bᶜ) = 0.4

iii) Probability that exactly one of the events A, B occurs = 0.7

Note: The provided values of P(A), P(A ∪ B), and the disjoint nature of A and B are used to derive the above probabilities.

we must rely on estimates instead

The population is larger than the sample, and the entire group of cases we want information on.

In statistics, a population refers to the whole set of people, items, or events under consideration.

The sample is a smaller subset of the population that is taken into account.

The sample should be an accurate representation of the population from which it was chosen in order for it to be useful in making predictions or generalizations about the population. Let's look at the options and select the correct ones.

(a) Larger than the sample:

The population is the entire collection of individuals, items, or events that a researcher is interested in studying, and it is always larger than the sample. It is vital to select a sample that represents the population well to make inferences about it.

(b) The entire group of cases we want information on:

The population is the entire collection of people, items, or events that a researcher is interested in studying. It is the group of individuals from which a sample is taken. A sample is a representative of the population.

(c) Impractical or too expensive to collect information from:

When the population size is too big, it is impractical or too expensive to collect information from it.

In such cases, we have to select a representative sample.

For example, it would be impossible to count all the people who have ever lived on the planet, so we must rely on estimates instead.

Given vectors u = [2x, x] and v = [x, 2x], we add them to get the vector [3x, 3x]. Solving |u+v|=9, we find x = sqrt(2) / 2.

The problem provides two vectors, u and v, and asks us to find the value of x such that the magnitude of the sum of these two vectors is equal to 9.  To find the sum of u and v, we simply add the corresponding components of each vector. This gives us the vector [2x, x] + [x, 2x] = [3x, 3x].

Next, we take the magnitude of the resulting vector by using the distance formula in two dimensions, which gives |[3x, 3x]| = sqrt((3x)^2 + (3x)^2) = sqrt(18x^2) = 3sqrt(2)x.

Since we are given that the magnitude of the sum of u and v is equal to 9, we can set |u + v| = 9 and solve for x.

Substituting the expression we found for |u + v|, we get 3sqrt(2)x = 9, which simplifies to x = 3 / (3sqrt(2)). Rationalizing the denominator gives x = sqrt(2) / 2.

Therefore, the solution for x is x = sqrt(2) / 2.

To minimize the total area, the wire should be cut into two equal pieces of 5 feet each. One piece will be used to form a circle, while the other piece will be used to form a square.

Let's first consider the piece of length x being formed into a circle. The circumference of a circle is given by the formula C = 2πr, where r is the radius. Since the length of wire available for the circle is x, we have x = 2πr. Solving for r, we get r = x / (2π).

The remaining piece of wire, with length 10 - x, is used to form a square. A square has four equal sides, so each side length of the square, denoted by s, is (10 - x) / 4.

To minimize the total area, we need to minimize the sum of the areas of the circle and the square. The area of a circle is given by A = πr², and the area of a square is given by A = s².

Substituting the values of r and s obtained earlier, we have:

Area of the circle: A_c = π(x / (2π))² = x² / (4π)

Area of the square: A_s = ((10 - x) / 4)² = (10 - x)² / 16

The total area is given by the sum of these two areas: A_total = A_c + A_s = x² / (4π) + (10 - x)² / 16.

To minimize the total area, we can take the derivative of A_total with respect to x, set it equal to zero, and solve for x. This will give us the value of x that minimizes the area. Once we find x, we can substitute it back into the expressions for r and s to find the radius of the circle and the side length of the square.

By calculating these values, we can determine the radius of the circle and the length of each side of the square.

We have 3 = (4/3)π(3r^2)(dr/dt). Now we can solve for dr/dt, the rate of change of the radius.

To find the rate at which the radius is increasing, we need to use the relationship between volume and radius of a sphere. The volume of a sphere is given by V = (4/3)πr^3, where V represents the volume and r represents the radius.

The problem states that helium is being pumped into the balloon at a rate of 3 cubic feet per second. Since the rate of change of volume is given, we can differentiate the volume equation with respect to time (t) to find the rate at which the volume is changing: dV/dt = (4/3)π(3r^2)(dr/dt).

We know that dV/dt = 3 cubic feet per second, and we need to find dr/dt, the rate of change of the radius. Since we're interested in the rate of change after 2 minutes, we convert the time to seconds: 2 minutes = 2 × 60 seconds = 120 seconds.

Plugging in the values, we have 3 = (4/3)π(3r^2)(dr/dt). Now we can solve for dr/dt, the rate of change of the radius.

I do not believe either of them because of the heights of both the R.F. Mitte Building and the tallest building in San Marcos.

The height that a projectile can reach in ideal conditions (i.e., without air resistance) can be estimated by the physics formula for kinetic and potential energy equivalence:

mgh = 1/2mv²

The R.F. Mitte Building is 100 feet tall, and the tallest building in San Marcos is 150 feet tall. The velocity of a baseball thrown at the top of these buildings would need to be at least 44.27 m/s and 54.22 m/s, respectively, in order for it to reach the top.

This is a very high velocity, and it is unlikely that a person could throw a baseball with that much force. The fastest recorded pitch in Major League Baseball was by Aroldis Chapman at 105.1 mph, which is approximately 47 m/s.

Therefore, while the claim to throw a ball on top of the R.F. Mitte Building might be achievable by a person in excellent physical condition but the claim to throw a baseball on top of the tallest building in San Marcos seems impossible.

A person claims they can toss a baseball on top of the R.F. Mitte Building. Not to be outdone, his buddy boasts he can throw a baseball on top of the tallest building in San Marcos.

Do you believe either of them and why?

The vector A = 5x + 12y makes an angle of approximately 67.38 degrees with the positive x-axis. This means that if you start at the origin and move in the direction of the positive x-axis, you would need to rotate counterclockwise by 67.38 degrees to align with the direction of vector A.

To find the angle between vector A and the positive x-axis, we can use trigonometry. The angle can be determined using the arctan function:

angle = arctan(y-component / x-component)

In this case, the y-component of vector A is 12y, and the x-component is 5x. Since x and y are unit vectors in the x- and y-directions respectively, their magnitudes are both 1.

angle = arctan(12 / 5)

Using a calculator, we find:

angle ≈ 67.38 degrees

Now, we need to calculate the threshold voltage of depletion mode VGS.

To calculate the VGS we will use the following formula:

VGS = √((2I_D/P.Kn′) + (VTN)²)

We know the values of I_D and P.Kn′:

I_D = (P)/VDD = 9.25 mW/3.3 V = 2.8 mA.

P.Kn′ = 100

μA/V² × (1.46/1) × 2.8 mA = 407.76.μA

Using the above values in the formula to find VGS we get:

VGS = √((2 × 407.76 μA)/(9.25 mW) + (0.6)²) = 0.674 V

Now, we can calculate the voltage drop across the load, which is represented as V₁:

V₁ = VDD - (I_D.Ro + Vro2)

V₁ = 3.3 - (2.8 mA × (1.46 kΩ/1)) - (-2 V) = 2.448 V

We can also calculate the voltage at the output of the switch, which is represented as VH.

To calculate the VH we will use the following formula:

VH = V₁ - (y/2) × (W/L)(VGS - VTN)²

We know the values of VGS, VTN, and y, and the ratio of (W/L) for the switch.

W/L = 1.46/1y = 0.5 √V = 0.5 √VGS - VTN = 0.5 √(0.674 - 0.6) = 0.0526

VH = 2.448 - (0.0263 × 1.46/1 × (0.0526)²) = 2.3475 V

Therefore, VH = 2.3475 V and V₁ = 2.448 V.

The evaluated indefinite integral is ∫(1/A) dx = x/A + C, where C is the constant of integration.

To evaluate the indefinite integral ∫(1/A) dx using a trigonometric substitution, we can substitute x = A tanθ, which leads to the integral becoming ∫(secθ) dθ. We can then solve this new integral and substitute back to find the final result.

To evaluate ∫(1/A) dx using a trigonometric substitution, we substitute x = A tanθ, where A is a constant. Taking the derivative of this substitution, we have dx = A sec^2θ dθ.

Substituting these expressions into the original integral, we obtain ∫(1/A) dx = ∫(1/A) (A sec^2θ dθ). Simplifying, we have ∫sec^2θ dθ.

The integral of sec^2θ is a well-known trigonometric integral, which evaluates to tanθ + C, where C is the constant of integration.

Substituting back for θ using the original substitution, we have tanθ = x/A. Solving for θ, we get θ = tan^(-1)(x/A).

Therefore, the final result of the integral ∫(1/A) dx using a trigonometric substitution is tan(tan^(-1)(x/A)) + C. Simplifying further, we have x/A + C.
