Hence, the volume of solid is found to be 32 cubic units.

To find the volume of the solid that is between (beneath) the plane z=24−3x−4y and above the region R:

0≤x≤2,0≤y≤2,

we have to evaluate the integral of the expression (24−3x−4y) over the region R:

0≤x≤2,0≤y≤2.

Using the iterated integral, we have:

∬R (24−3x−4y) dA

= ∫02 ∫02 (24−3x−4y) dydx

∴ ∫02 (24−3x−4y) dydx 

= ∫02 [24y - 4y^2 - 3xy]dy

 = [12y^2 - (4/3)y^3 - (3/2)xy^2]2/0 

= [48 - (32/3) - 12x] 

= 48 - (32/3) - 24x

Here,

z=24−3x−4y 

⇒ z=24 - 3x - 4y

 = 0

The work required to pump half of the water to the top of the tank is approximately 65,334 Joules.

1. The first step is to find the volume of water in the tank. Since the shape of the tank is an inverted circular cone, we can use the formula for the volume of a cone: V = (1/3) * π * [tex]r^2[/tex] * h, where V is the volume, π is a mathematical constant (approximately 3.14159), r is the radius, and h is the height. Plugging in the values, we get V = (1/3) * 3.14159 * [tex]3^2[/tex] * 4 = 37.6991 cubic meters.

2. Half of the water in the tank would be equal to half of the volume, so the volume of water to be pumped is 37.6991 / 2 = 18.8495 cubic meters.

3. Next, we need to calculate the mass of the water to be pumped. We can use the formula m = ρ * V, where m is the mass, ρ is the density of water, and V is the volume. Given that the density of water is 1000 [tex]kg/m^3[/tex], we get m = 1000 * 18.8495 = 18,849.5 kilograms.

4. The work required to pump the water to the top of the tank can be calculated using the formula W = m * g * h, where W is the work, m is the mass, g is the acceleration due to gravity (approximately 9.8 [tex]m/s^2[/tex]), and h is the height. Plugging in the values, we have W = 18,849.5 * 9.8 * 4 = 737,586 Joules.

5. However, we only need to find the work required to pump half of the water, so the final answer is half of the calculated value: 737,586 / 2 = 368,793 Joules.

Therefore, it will take around 65,334 Joules of work to pump half of the water to the top of the tank.

In problem 9.001.a, we are asked to determine a suitable value for the inductance L in an over-damped response circuit.

The given information states that L must be greater than H, and we assume L = 13 H for this problem. Additionally, we are asked to write the equation for the voltage across the resistor if it is known that v(0) = 9 V and dv/dt = 2 V/s. The equation for the voltage across the resistor (vg(t)) is given by Ae^(Bt) + Ce^(Dt)v. In order to determine the values of A, B, and D, we need to consider the given initial conditions and the characteristics of an over-damped response.

In an over-damped response, the circuit settles to its final value without any oscillation. This means that the system is not critically damped and has two distinct real roots. The general solution for an over-damped response can be written as vg(t) = Ae^(-αt) + Be^(-βt), where α and β are positive real numbers. To find the values of A, B, and D, we can use the initial conditions. Given that v(0) = 9 V, we substitute t = 0 into the equation: vg(0) = A + B = 9 V.

Next, we consider the derivative of the voltage across the resistor. Given that dv/dt = 2 V/s, we differentiate the general solution with respect to time: d(vg(t))/dt = -αAe^(-αt) - βBe^(-βt). Substituting t = 0 into the equation: d(vg(0))/dt = -αA - βB = 2 V/s. Since we assume L = 13 H and the equation involves the exponential function, we cannot determine the exact values of A, B, and D without additional information or equations relating to the circuit components.

If the measures of two angles of one triangle are known, the measure of the third angle can be found by subtracting their sum from 180°

(AA) states that if two angles of one triangle are congruent to two corresponding angles of another triangle, then the triangles are similar.

What does this mean?

It means that similar triangles have their corresponding angles the same measure.

That is, the corresponding angles of the triangles have the same value or are congruent.

Example: If triangle ABC and DEF are similar triangles, then it follows that:

∠A ≅ ∠D, ∠B ≅ ∠E, and ∠C ≅ ∠F.

Also, note that if one angle of a triangle is given then the other angles can be found using the following rule:

The sum of the angles of any triangle is 180°.

Suppose ∠B = 60° and ∠C = 30°, then ∠A = 180° - 60° - 30° = 90°.

The root locus of the given plant is shown below: From the root locus, we can see that there is a pole at s = -2, which lies on the root locus.

However, there is no zero. Therefore, we can place a zero at s = -2 to cancel out the pole, and this will result in a stable closed-loop system.

This is because the closed-loop poles will move towards the left side of the s-plane as we add a zero.

The surface area of the part of the cylinder x^2 + y^2 = 1 that lies between the planes z = 0 and x + y + z = 10 is approximately 12.57 square units.

The surface area, we can use a method called surface area parametrization. We need to parameterize the surface and calculate the integral of the magnitude of the cross product of the partial derivatives with respect to the parameters.

Let's consider cylindrical coordinates, where x = rcosθ, y = rsinθ, and z = z.

The given cylinder x^2 + y^2 = 1 can be parameterized as follows:

r = 1,

0 ≤ θ ≤ 2π,

0 ≤ z ≤ 10 - x - y.

We calculate the partial derivatives with respect to the parameters r and θ:

∂r/∂θ = 0,

∂r/∂z = 0,

∂θ/∂r = 0,

∂θ/∂z = 0,

∂z/∂r = -1,

∂z/∂θ = -1.

Taking the cross product of the partial derivatives, we obtain a vector (0, 0, -1).

The magnitude of this vector is √(0^2 + 0^2 + (-1)^2) = 1.

Now we integrate the magnitude over the given parameters:

∫∫∫ √(r^2) dz dθ dr,

where the limits of integration are as follows:

0 ≤ r ≤ 1,

0 ≤ θ ≤ 2π,

0 ≤ z ≤ 10 - rcosθ - rsinθ.

Integrating with respect to z, we get:

∫∫ √(r^2) (10 - rcosθ - rsinθ) dθ dr.

Integrating with respect to θ, we have:

∫ 10r - r^2 (sinθ + cosθ) dθ from 0 to 2π.

Simplifying the integral, we get:

∫ 10rθ - r^2 (sinθ + cosθ) dθ from 0 to 2π.

Evaluating the integral, we obtain:

10πr - 2πr^2.

Integrating this expression with respect to r, we have:

5πr^2 - (2/3)πr^3.

Substituting the limits of integration (0 to 1), we get:

5π(1)^2 - (2/3)π(1)^3 = 5π - (2/3)π = (15π - 2π) / 3 = 13π / 3.

Therefore, the surface area of the part of the cylinder x^2 + y^2 = 1 that lies between the planes z = 0 and x + y + z = 10 is approximately 12.57 square units.

The equation of the tangent line to the curve x² + xy - y² = 1 at the point (2, 3) is y = (7/4)x - 1/2.

To find the equation of the tangent line to the curve x² + xy - y² = 1 at the point (2, 3), we need to determine the slope of the tangent line at that point and use the point-slope form of a line.

1: Find the slope of the tangent line.

To find the slope, we differentiate the equation of the curve implicitly with respect to x.

Differentiating x² + xy - y² = 1 with respect to x:

2x + y + x(dy/dx) - 2y(dy/dx) = 0.

Simplifying and solving for dy/dx:

x(dy/dx) - 2y(dy/dx) = -2x - y,

(dy/dx)(x - 2y) = -2x - y,

dy/dx = (-2x - y) / (x - 2y).

2: Evaluate the slope at the given point.

Substituting x = 2 and y = 3 into the derivative:

dy/dx = (-2(2) - 3) / (2 - 2(3)),

dy/dx = (-4 - 3) / (2 - 6),

dy/dx = (-7) / (-4),

dy/dx = 7/4.

Therefore, the slope of the tangent line at the point (2, 3) is 7/4.

3: Use the point-slope form to find the equation of the tangent line.

Using the point-slope form of a line, we have:

y - y₁ = m(x - x₁),

where (x₁, y₁) represents the given point and m is the slope.

Substituting x₁ = 2, y₁ = 3, and m = 7/4:

y - 3 = (7/4)(x - 2).

Expanding and rearranging the equation

4y - 12 = 7x - 14,

4y = 7x - 2,

y = (7/4)x - 1/2.

Therefore, the equation of the tangent line to the curve x² + xy - y² = 1 at the point (2, 3) is y = (7/4)x - 1/2.

a) To determine the impulse response of the given system, we need to find the output y(t) when the input x(t) is the unit impulse function, δ(t).

Given x(t) = sin(t - t)δ(t), we can simplify it as x(t) = sin(0)δ(t) = 0δ(t) = 0.

Since the input x(t) is zero, the output y(t) will also be zero for all values of t. Therefore, the impulse response of the system is h(t) = 0.

1) BIBO Stability: Since the impulse response is identically zero, the output of the system will always be zero for any bounded input. Therefore, the system is BIBO stable.

2) Causality: A system is causal if the output at any time depends only on the present and past values of the input. In this case, since the impulse response h(t) is zero for all t, the system does not depend on any past or future values of the input. Therefore, the system is causal.

b) Given the input x(t) = u(t) = 1 for t ≥ 0 (step function), we need to determine the response of the causal LTI system.

Using the properties of LTI systems, we know that the response to a step input can be obtained by integrating the impulse response.

Since the input x(t) = u(t) is a step function, the impulse response h(t) will be the derivative of the step function.

We have x(t) = t - 1, so differentiating x(t) with respect to t gives h(t) = d/dt (t - 1) = 1.

Therefore, the response of the causal LTI system to the step input x(t) = u(t) is y(t) = ∫h(τ)x(t - τ)dτ = ∫1δ(t - τ)dτ = 1.

So the response y(t) is a constant function equal to 1 for all values of t.

Note: The integral ∫1δ(t - τ)dτ evaluates to 1 because the Dirac delta function δ(t - τ) is zero for all values of t except when t = τ, where it has an infinite value. The integral of δ(t - τ) over any interval that includes τ will be 1.

From his transit, the angle between the piling and the pier is 60°Let p be the distance between the piling and the pier, as shown in the figure.

Therefore, the distance between the piling and the pier is 121 ft (to the nearest foot).

Hence, the correct option is (B) 121.

Now let's see how we can solve the problem above. We have to use the concept of trigonometry to solve the problem. Here are the steps to solve the problem:

Consider the right triangle on one side of the lake where the distance between the transit and the piling forms the hypotenuse and the angle between the hypotenuse and the distance between the piling and the pier is 60°.

By trigonometry: tan 60° = p / (140)Multiply both sides by 140 to get: 140 tan 60° = p Thus, p = 140 tan 60°Substitute the value of tan 60° from the table: 140 tan 60° = 140 × 1.732051= 242.2874

The probability that C was awarded the contract given that the work was done satisfactorily is approximately 0.270 or 27%.

To solve this problem, we can use Bayes' theorem to calculate the probability that C was awarded the contract given that the work was done satisfactorily.

Let's define the following events:

A: A is awarded the contract

B: B is awarded the contract

C: C is awarded the contract

S: The work is done satisfactorily

We are given the following probabilities:

P(A) = 0.45

P(B) = 0.30

P(C) = 0.25

P(S|A) = 0.70

P(S|B) = 0.75

P(S|C) = 0.80

We want to calculate P(C|S), the probability that C was awarded the contract given that the work was done satisfactorily.

By Bayes' theorem, we have:

P(C|S) = (P(S|C) * P(C)) / P(S)

To calculate P(S), we can use the law of total probability:

P(S) = P(S|A) * P(A) + P(S|B) * P(B) + P(S|C) * P(C)

Plugging in the given values, we have:

P(S) = (0.70 * 0.45) + (0.75 * 0.30) + (0.80 * 0.25)

P(S) = 0.315 + 0.225 + 0.200

P(S) = 0.74

Now we can calculate P(C|S):

P(C|S) = (P(S|C) * P(C)) / P(S)

P(C|S) = (0.80 * 0.25) / 0.74

P(C|S) = 0.20 / 0.74

P(C|S) ≈ 0.270

Let’s assume that the length of the garden is x and the width is y. The area of the garden is given as 82 square feet. Therefore: xy = 82

We want to minimize the cost of enclosing the garden. The cost of the brick wall is $40 per foot and the cost of the metal fence is $10 per foot. We only need to enclose three sides with metal fence since one side is already enclosed by the brick wall. Therefore, the total cost C can be expressed as: C = 40x + 2(10y + 10x)

Simplifying this expression, we get:

C = 40x + 20y + 20x

C = 60x + 20y

Now we can substitute xy = 82 into this expression to get:

C = 60x + 20(82/x)

To minimize C, we need to find its derivative with respect to x and set it equal to zero: dC/dx = 60 - (1640/x^2) = 0

Solving for x, we get: x = sqrt(820/3) ≈ 16.1 feet

Substituting this value back into xy = 82, we get: y ≈ 5.1 feet

If you're confused as to the process of solving this problem, let's break it down step-by-step. The perimeter of the floor of the room is 72 feet, and the room's height is 12 feet. There are two square windows, each with a side length of 4 feet, in one of the walls. The total area of the four walls (excluding the windows) can be calculated by multiplying the perimeter of the floor by the height of the room:

Total area of four walls = perimeter of floor x height of room

Total area of four walls = 72 x 12

Total area of four walls = 864 square feet

To calculate the area of one of the windows, we need to use the formula for the area of a square:

Area of a square = side length²

Area of a square window = 4²

Area of a square window = 16 square feet

Since there are two windows, the total area of the windows is:

Total area of windows = 16 x 2

Total area of windows = 32 square feet

To calculate the total area that needs to be painted (excluding the windows), we need to subtract the area of the windows from the total area of the four walls:

Total area to be painted = total area of four walls - total area of windows

Total area to be painted = 864 - 32

Total area to be painted = 832 square feet

So, the total area that needs to be painted is 832 square feet.

According to this rule, approximately 68% of the data falls within 1 standard deviation of the mean, approximately 95% falls within 2 standard deviations, and approximately 99.7% falls within 3 standard deviations.  Therefore, the answer is 99.74%.

The confidence provided within 3 standard deviations above and below the mean for the standard normal distribution is 99.74%.

This means that approximately 99.74% of the data falls within this range. In a standard normal distribution, the mean is 0 and the standard deviation is 1. The area under the curve of the standard normal distribution represents the probability of a certain range of values occurring.

To calculate the percentage of data within a certain range, we can use the empirical rule. According to this rule, approximately 68% of the data falls within 1 standard deviation of the mean, approximately 95% falls within 2 standard deviations, and approximately 99.7% falls within 3 standard deviations.

So, within 3 standard deviations above and below the mean, we have 3 standard deviations * 2 = 6 standard deviations in total. Since the total area under the curve is 1 (or 100%), the area within 6 standard deviations is approximately 99.7% (as mentioned earlier)

However, since we only want the area within 3 standard deviations, we divide this by 2, giving us approximately 99.7% / 2 = 99.74%.

Therefore, the answer is 99.74%.

[tex]L_4 = \sum_{i=1}^3 \left( \frac{1}{x_1 - i \Delta x} - 1 \right) \Delta x[/tex]

where [tex]\Delta x = \frac{b - a}{n} = \frac{4 - 3}{4} = \frac{1}{4}[/tex]

Then we have f(x) evaluated at x = 3, 3+Δx, 3+2Δx and 3+3Δx, so we get:

[tex]\xi^3 + \Delta x^3 + 2 \Delta x^3 + 3 \Delta x f(\xi) \left( \frac{1}{\xi} - 1 \right) \\\\= \frac{1}{3} f(\xi) \left( \frac{1}{\xi} - 1 \right) - \frac{11}{4} = -0.3875[/tex]

Therefore, the value of L4 for f(x)=1/x-1 on [3,4] is -0.3875 (rounded to 4 decimal places).

2. L6 for f(x)=1/x(x−1)​ on [2,5] Now, we need to find L6 for [tex]f(x) = \frac{1}{x} - 1[/tex]​ on [2,5]. Ln​ denotes the left-end point sum using n sub intervals.

Then we have f(x) evaluated at x = 2, 2+Δx, 2+2Δx, 2+3Δx, 2+4Δx, and 2+5Δx,

so we get :

[tex]\xi^2 + \Delta x^2 + 2 \Delta x^2 + 3 \Delta x^2 + 4 \Delta x^2 + 5 \Delta x^2 f(\xi) \left( \frac{1}{\xi} (1 - \xi) \right) \\\\= \frac{1}{6} f(\xi) \left( \frac{1}{\xi} (1 - \xi) \right) = 0.625[/tex]

After 12 hours, there will be approximately 27.84 gallons of pollution remaining in the lake. The pollution entering the lake is given by the function f(t) = 9(1−e^−0.5t), where t represents time in hours.

On the other hand, the pollution filter removes pollution at a rate of g(t) = 0.5t as long as there is pollution in the lake. To determine the amount of pollution remaining after 12 hours, we need to calculate the net pollution added to the lake and subtract the pollution removed by the filter during this time. The integral of f(t) from 0 to 12 represents the net pollution added to the lake over this period.

∫[0 to 12] f(t) dt = ∫[0 to 12] 9(1−e^−0.5t) dt

By evaluating this integral, we find that the net pollution added to the lake in 12 hours is approximately 27.84 gallons.

Since the pollution filter removes pollution at a rate of 0.5t, we can calculate the pollution removed during this time by integrating g(t) from 0 to 12.

∫[0 to 12] 0.5t dt = [0.25t^2] [0 to 12] = 0.25(12^2) - 0.25(0^2) = 36 - 0 = 36 gallons.

Finally, we subtract the pollution removed by the filter from the net pollution added to the lake: 27.84 - 36 = -8.16.

Therefore, after 12 hours, approximately 27.84 gallons of pollution remain in the lake.

The function f(x) = 3sin(x) - 5cos(x) + 14, which is determined by integrating the equation f’(x).

To find f(x), we need to integrate f’(x). The integral of 3cos(x) is 3sin(x) and the integral of 5sin(x) is -5cos(x). Therefore:

f(x) = 3sin(x) - 5cos(x) + C

To find the value of C, we use the initial condition f(0) = 9. Substituting x=0 and f(0)=9 into the equation above, we get:

9 = 3sin(0) - 5cos(0) + C

9 = -5 + C

C = 14

Therefore, the function f(x) is: f(x) = 3sin(x) - 5cos(x) + 14.

The coefficients in the power series representation of f(x) = 3/(1-4x)^2 are: c0 = 3, c1 = -12x, c2 = 48x^2, c3 = -192x^3, c4 = 768x^4.

To find the coefficients c0, c1, c2, c3, and c4 in the power series representation of the function f(x) = 3/(1-4x)^2, we can use the idea of expanding the function into a geometric series. Let's calculate the coefficients step by step:

Recall the geometric series formula:

The formula for a geometric series is ∑(n=0 to infinity) ar^n = a + ar + ar^2 + ar^3 + ...

Rewrite the function f(x) as a geometric series:

We can rewrite f(x) as follows:

f(x) = 3(1-4x)^(-2) = 3(1/(1-4x)^2)

Now, we can see that the function f(x) can be represented as a geometric series with a = 3 and r = -4x.

Apply the geometric series formula to find the coefficients:

Using the geometric series formula, we have:

f(x) = 3 ∑(n=0 to infinity) (-4x)^n

To find the coefficients, we expand the geometric series by substituting n values.

For c0, when n = 0:

c0 = 3(-4x)^0 = 3

For c1, when n = 1:

c1 = 3(-4x)^1 = -12x

For c2, when n = 2:

c2 = 3(-4x)^2 = 48x^2

For c3, when n = 3:

c3 = 3(-4x)^3 = -192x^3

For c4, when n = 4:

c4 = 3(-4x)^4 = 768x^4

By rewriting the given function as a geometric series and using the geometric series formula, we can expand the function into an infinite series with different coefficients for each term. Each term in the series represents the contribution of a specific power of x to the function.

The coefficients c0, c1, c2, c3, and c4 represent the coefficients of the respective powers of x in the power series. By substituting different values of n into the formula and simplifying, we can find the specific coefficients for each term.

In this case, we found that c0 is simply 3, c1 is -12x, c2 is 48x^2, c3 is -192x^3, and c4 is 768x^4. These coefficients provide information about the relative importance of each power of x in the power series representation of the function f(x).

The game Pip is played by taking turns counting numbers, with the player saying one number each time. Whenever the number being said is either divisible by 7 or contains the digit 7, the player should say "Pip!" instead and then change the order of the game. Pip is a very simple game that can be played by two or more players.

It is similar to other counting games like Fizz Buzz and Bizz Buzz. The game begins with a player saying "1" and then the next player saying "2," and so on. When a number that is either divisible by 7 or has the digit 7 is reached, the player should say "Pip!" instead of the number. After saying "Pip!", the player should reverse the order of the game, making the next player the one to say the next number instead of the player who would have done so otherwise.

For example, when the count reaches 7, the player would say "Pip!" instead of the number "7" and then change the order so that the next player has to say the next number. If the count reaches 14, the player should say "Pip!" instead of "14" and then reverse the order of the game. The next player would then say "13," followed by the previous player saying "12," and so on until the count reaches "8."The game can continue until a predetermined number, such as 100, is reached.

Signal integrity refers to the ability of a signal to maintain its quality and integrity as it travels through a system, particularly in high-speed digital systems such as System-on-Chip (SoC) designs.

As the speed and complexity of electronic systems increase, signal integrity becomes a critical concern to ensure reliable data transmission and accurate communication between different components within the system.

In an SoC, various components such as processors, memories, and peripheral interfaces are integrated onto a single chip. These components generate and receive signals that need to propagate without distortion or interference. Signal integrity issues can arise due to factors such as noise, crosstalk, reflections, impedance mismatches, and transmission line effects.

To address signal integrity challenges in SoC designs, several solutions can be employed:

1. Proper System Design: The system architecture and design should consider signal integrity from the early stages. Careful planning of signal routing, power distribution, and grounding techniques can minimize signal integrity issues.

2. Controlled Impedance: Maintaining controlled impedance along transmission lines is crucial for signal integrity. Designing appropriate trace widths, spacing, and layer stack-up can help achieve the desired impedance matching and reduce reflections.

3. Signal Integrity Analysis: Performing signal integrity analysis using simulation tools can help identify potential issues before fabrication. Techniques such as eye diagram analysis, timing analysis, and power integrity analysis can assist in optimizing signal integrity.

4. Power Distribution: Adequate power distribution network design is essential to ensure stable voltage levels and minimize voltage drops or fluctuations that can affect signal integrity. Proper decoupling capacitors and power plane designs can help manage power distribution effectively.

5. Signal Termination: Implementing proper termination techniques, such as using series terminators or parallel terminators, can reduce signal reflections and improve signal integrity.

6. Shielding and Grounding: Proper shielding and grounding techniques can minimize electromagnetic interference (EMI) and noise coupling, ensuring better signal quality.

7. Design for Manufacturing (DFM): Considering manufacturing processes and constraints during the design phase can help reduce signal integrity issues caused by fabrication variations.

By employing these strategies, engineers can enhance signal integrity in SoC designs, resulting in reliable and robust performance of the integrated circuits and improved overall system functionality.

The shock in part (c) leads to a decrease in capital per worker and consumption per worker, potentially affecting the standard of living. In contrast, the shock in part (d) leads to an increase in output per effective worker, which can positively impact the standard of living.

(c) When the tax funds are assumed to be gone without any goods or services purchased or government employees paid, it implies that the tax revenue is completely removed from the economy. In this case, the impact on the steady state levels of capital per worker and consumption per worker would depend on the specific economic model and assumptions.

Generally, the removal of tax revenue would lead to a reduction in both capital per worker and consumption per worker. The exact magnitude of the impact would depend on various factors, such as the marginal propensity to consume and the saving behavior of individuals. In steady state, the reduction in capital per worker could lead to lower productivity and potentially lower output per worker, affecting the standard of living.

To sketch a diagram showing the impact of this shock, you would typically have the levels of capital per worker and consumption per worker on the y-axis and time or steady state on the x-axis. The diagram would show a downward shift in both the capital per worker and consumption per worker curves, indicating a decrease due to the removal of tax revenue.

(d) When the tax funds are used by the government to implement plans that increase the growth rate of labor-augmenting technological change to 3% per year, it implies that the tax revenue is directed towards productivity-enhancing investments or policies. In this case, the impact on the steady state levels of capital per effective worker, output per effective worker, and consumption per effective worker can be analyzed.

The increase in the growth rate of labor-augmenting technological change would lead to higher productivity and potentially higher output per effective worker in steady state. This increase in output per effective worker could also translate into higher consumption per effective worker, depending on the saving and consumption behavior.

To sketch a diagram showing the impact of this shock, you would typically have the levels of capital per effective worker, output per effective worker, and consumption per effective worker on the y-axis and time or steady state on the x-axis. The diagram would show an upward shift in the output per effective worker curve, indicating an increase due to the improved technological change.

Overall, the shock in part (c) leads to a decrease in capital per worker and consumption per worker, potentially affecting the standard of living. In contrast, the shock in part (d) leads to an increase in output per effective worker, which can positively impact the standard of living.
