Step 1: The solution for the indicated variable b is b = ±√a.

Step 2: To solve the equation a + b² = ² for b, we need to isolate the variable b.

First, let's subtract 'a' from both sides of the equation: b² = ² - a.

Next, we take the square root of both sides to solve for b: b = ±√(² - a).

Since the question specifies that b > 0, we can discard the negative square root solution. Therefore, the solution for b is b = √(² - a).

Step 3: In the given equation, a + b² = ², we need to solve for the variable b. To do this, we follow a few steps. First, we subtract 'a' from both sides of the equation to isolate the term b²: b² = ² - a. Next, we take the square root of both sides to solve for b. However, we must consider that the question specifies b > 0. Therefore, we discard the negative square root solution and obtain the final solution: b = √(² - a). This means that the value of b is equal to the positive square root of the quantity (² - a).

The equation of motion for the cone in the regime of small oscillations is ∫₀ˣ₀ (h - θ × r)² × dθ × ω' × ω = ω' × ω × ∫₀ˣ₀ (h - θ × r)² × dθ.

To write the equation for the motion of the cone in the regime of small oscillations, we need to consider the forces acting on the cone and apply Newton's second law of motion. In this case, the cone experiences two main forces: gravitational force and the force due to the constraint of rolling without slipping.

Let's define the following variables:

- θ: Angular displacement of the cone from its equilibrium position (measured in radians)

- ω: Angular velocity of the cone (measured in radians per second)

- h: Height of the cone

- p: Density of the cone

- g: Acceleration due to gravity

The gravitational force acting on the cone is given by the weight of the cone, which is directed vertically downwards and can be calculated as:

F_gravity = -m × g,

where m is the mass of the cone. The mass of the cone can be obtained by integrating the density over its volume. In this case, since the density is a function of the angular coordinate w, we need to express the mass in terms of θ.

The mass element dm at a given angular displacement θ is given by:

dm = p × dV,

where dV is the differential volume element. For a cone, the volume element can be expressed as:

dV = (π / 3) × (h - θ × r)² × r × dθ,

where r is the radius of the cone at height h - θ × r.

Integrating dm over the volume of the cone, we get the mass m as a function of θ:

m = ∫₀ˣ₀ p × (π / 3) × (h - θ × r)² × r × dθ,

where the limits of integration are from 0 to θ₀ (the equilibrium position).

Now, let's consider the force due to the constraint of rolling without slipping. This force can be decomposed into two components: a tangential force and a normal force. Since the cone is in a horizontal position, the normal force cancels out the gravitational force, and we are left with the tangential force.

The tangential force can be calculated as:

F_tangential = m × a,

where a is the linear acceleration of the center of mass of the cone. The linear acceleration can be related to the angular acceleration α by the equation:

a = α × r,

where r is the radius of the cone at the center of mass.

The angular acceleration α can be related to the angular displacement θ and angular velocity ω by the equation:

α = d²θ / dt² = (dω / dt) = dω / dθ × dθ / dt = ω' × ω,

where ω' is the derivative of ω with respect to θ.

Combining all these equations, we have:

m × a = m × α × r,

m × α = (dω / dt) = ω' × ω.

Substituting the expressions for m, a, α, and r, we get:

∫₀ˣ₀ p × (π / 3) × (h - θ × r)² × r × dθ × ω' × ω = ω' × ω × ∫₀ˣ₀ p × (π / 3) × (h - θ × r)² × r × dθ.

Now, in the regime of small oscillations, we can make an approximation that sin(θ) ≈ θ, assuming θ is small. With this approximation, we can rewrite the equation as follows:

∫₀ˣ₀ p × (π / 3) × (h - θ × r)² × r × dθ × ω' × ω = ω' × ω × ∫₀ˣ₀ p × (π / 3) × (h - θ × r)² × r × dθ.

We can simplify this equation further by canceling out some terms:

∫₀ˣ₀ (h - θ × r)² × dθ × ω' × ω = ω' × ω × ∫₀ˣ₀ (h - θ × r)² × dθ.

This equation represents the equation of motion for the cone in the regime of small oscillations. It relates the angular displacement θ, angular velocity ω, and their derivatives ω' to the properties of the cone such as its height h, density p, and radius r. Solving this equation will give us the behavior of the cone in the small oscillation regime.

Answer:

The MP curve initially rises to its maximum value because of the specialized nature of the fixed capital, where each additional worker's productivity rises due to the marginal product of the fixed capital.

Production Function: q = f(L,K) = 20L + 25K + 5KL - 0.03L² - 0.02K²

Given, K = 5, i.e., capital is fixed. Therefore, the total product of labor, average product of labor, and marginal product of labor are:

TPL = f(L, K = 5) = 20L + 25 × 5 + 5L × 5 - 0.03L² - 0.02(5)²

= 20L + 125 + 25L - 0.03L² - 5

= -0.03L² + 45L + 120

APL = TPL / L, or APL = 20 + 125/L + 5K - 0.03L - 0.02K² / L

= 20 + 25 + 5 × 5 - 0.03L - 0.02(5)² / L

= 50 - 0.03L - 0.5 / L

= 49.5 - 0.03L / L

MP = ∂TPL / ∂L

= 20 + 25 - 0.06L - 0.02K²

= 45 - 0.06L

The following diagram illustrates the TP, MP, and AP curves:

Figure: Total Product (TP), Marginal Product (MP), and Average Product (AP) curves

The production function demonstrates increasing marginal returns due to specialization when L is low enough, i.e., when L ≤ 750. The marginal product curve initially increases and reaches a maximum value of 45 units of output when L = 416.67 units. When L > 416.67, MP decreases, and when L = 750 units, MP becomes zero.

The MP curve's initial increase demonstrates that the production function displays increasing marginal returns due to specialization when L is low enough. This is because when the capital is fixed, an additional unit of labor will benefit from the fixed capital and will increase production more than the previous one.

In other words, Because of the specialised nature of the fixed capital, the MP curve first climbs to its maximum value, where each additional worker's productivity rises due to the marginal product of the fixed capital.

The APL curve initially rises due to the MP curve's increase and then decreases when MP falls because of the diminishing marginal returns.

The average angular speed of the hand is ω = 1800 / t rad/s and 103140 / t degrees/s and the average linear speed of the hand is 5D / t m/s.  The answers to A and B are not the same as they refer to different quantities with different units and different values.

A) To find the average angular speed of the hand, we need to use the formula:

angular speed (ω) = (angular displacement (θ) /time taken(t))

= 5 × 360 / t

Here, t is the time for 5 rotations

So, average angular speed of the hand is ω = 1800 / trad/s

To convert this into degrees/s, we can use the conversion:

1 rad/s = 57.3 degrees/s

Therefore, ω in degrees/s = (ω in rad/s) × 57.3

= (1800 / t) × 57.3

= 103140 / t degrees/s

B) To find the average linear speed of the hand, we need to use the formula:linear speed (v) = distance (d) /time taken(t)

Here, the distance of the hand is the length of the arm.

Distance from shoulder to middle of hand = D

Similarly, the time taken to complete 5 rotations is t

Thus, the total distance covered by the hand in 5 rotations is D × 5

Therefore, average linear speed of the hand = (D × 5) / t

= 5D / t

= 5 × distance of hand / time for 5 rotations

C) No, the answers to A and B are not the same. This is because angular speed and linear speed are different quantities. Angular speed refers to the rate of change of angular displacement with respect to time whereas linear speed refers to the rate of change of linear displacement with respect to time. Therefore, they have different units and different values.

The Gram-Schmidt process applied to the basis {1, t, t^2} in the vector space of polynomials with degree at most 2, denoted as V = P3, results in the orthogonal basis {1, t, t^2}, where the inner product is defined as f(+)g(t)dz.

The Gram-Schmidt process is a method used to transform a given basis into an orthogonal basis by constructing orthogonal vectors one by one. In this case, the given basis {1, t, t^2} is already linearly independent, so we can proceed with the Gram-Schmidt process.

We start by normalizing the first vector in the basis, which is 1. The normalized vector is obtained by dividing it by its magnitude, which is the square root of its inner product with itself. Since the inner product is f(+)g(t)dz and the degree is at most 2, the square root of the inner product of 1 with itself is √(1+0+0) = 1. Hence, the normalized vector is 1.

Next, we consider the second vector in the basis, which is t. To obtain an orthogonal vector, we subtract the projection of t onto the already orthogonalized vector 1. The projection of t onto 1 is given by the inner product of t with 1 divided by the inner product of 1 with itself, multiplied by 1. Since the inner product of t with 1 is f(+)g(t)dz and the inner product of 1 with itself is 1, the projection of t onto 1 is f(+)g(t)dz. Subtracting this projection from t gives us an orthogonal vector, which is t - f(+)g(t)dz.

Finally, we consider the third vector in the basis, which is t^2. Similarly, we subtract the projections of t^2 onto the already orthogonalized vectors 1 and t. The projection of t^2 onto 1 is f(+)g(t)dz, and the projection of t^2 onto t is (t^2)(+)g(t)dz. Subtracting these projections from t^2 gives us an orthogonal vector, which is t^2 - f(+)g(t)dz - (t^2)(+)g(t)dz.

After performing these steps, we end up with an orthogonal basis {1, t, t^2}, which is obtained by applying the Gram-Schmidt process to the original basis {1, t, t^2} in the vector space of polynomials with degree at most 2, V = P3. The inner product in this vector space is defined as f(+)g(t)dz.

The expression x⁴ + 8x³ + 34x² + 72x + 81 cannot be factored further using simple integer coefficients. It does not have any rational roots or easy factorizations. Therefore, it remains as an irreducible polynomial.

The correct solution to the equation 3x = 11 is x = ln11 - ln3.

To solve the equation 3x = 11, we can use logarithmic properties to isolate the variable x. Taking the natural logarithm (ln) of both sides, we have ln(3x) = ln(11). Using the logarithmic rule for the product of terms, we can rewrite ln(3x) as ln(3) + ln(x).

Therefore, the equation becomes ln(3) + ln(x) = ln(11). Rearranging the terms, we have ln(x) = ln(11) - ln(3). By the logarithmic property of subtraction, we can combine the logarithms, resulting in ln(x) = ln(11/3). Finally, exponentiating both sides with base e, we find x = ln(11/3).

The distance between the pair of parallel lines with the equations y = (1/2)x + 7/2 and y = (1/2)x + 1 is 1.67 units.

To find the distance between two parallel lines, we need to determine the perpendicular distance between them. Since the slopes of the given lines are equal (both lines have a slope of 1/2), they are parallel.

To calculate the distance, we can take any point on one line and find its perpendicular distance to the other line. Let's choose a convenient point on the first line, y = (1/2)x + 7/2. When x = 0, y = 7/2, so we have the point (0, 7/2).

Now, we'll use the formula for the perpendicular distance from a point (x₁, y₁) to a line Ax + By + C = 0:

Distance = |Ax₁ + By₁ + C| / √(A² + B²)

For the line y = (1/2)x + 1, the equation can be rewritten as (1/2)x - y + 1 = 0. Substituting the values from our point (0, 7/2) into the formula, we get:

Distance = |(1/2)(0) - (7/2) + 1| / √((1/2)² + (-1)²)

        = |-(7/2) + 1| / √(1/4 + 1)

        = |-5/2| / √(5/4 + 1)

        = 5/2 / √(9/4)

        = 5/2 / (3/2)

        = 5/2 * 2/3

        = 5/3

        = 1 2/3

We only have a ratio between P1 and P2, we cannot determine the exact values of P1 and P2. Therefore, we cannot find the exact sum of money based on the given information.

To solve this problem, we can use the formula for simple interest:

I = P * r * t

where:

I is the interest earned,

P is the principal sum (the initial amount of money),

r is the interest rate, and

t is the time in years.

Let's assign variables to the given information:

Principal sum in 3 years: P1

Principal sum in 4 years: P2

Interest earned in 3 years: I1 = $3120

Interest earned in 4 years: I2 = $3000

Time in years: t1 = 3, t2 = 4

Using the formula, we can set up two equations:

I1 = P1 * r * t1

I2 = P2 * r * t2

Substituting the given values:

3120 = P1 * r * 3

3000 = P2 * r * 4

Dividing the second equation by 4:

750 = P2 * r

Now, we can solve for P1 and P2. To eliminate the interest rate (r), we can divide the two equations:

(3120 / 3) / (3000 / 4) = (P1 * r * 3) / (P2 * r * 4)

1040 = (P1 * 3) / P2

Now, we have a ratio between P1 and P2:

P1 / P2 = 1040 / 3

To find the sum of money, we can add P1 and P2:

Sum = P1 + P2

a. the costs of non-compliance, enforcement, prevention and evaluation are -75 d/p, -$7500, $17500 and $5000 respectively

b. The percentage of effort devoted to each component is:

a) To calculate the costs of non-compliance, enforcement, prevention, and evaluation, we need to determine the deviations in effort for each component and multiply them by the corresponding cost per person-day.

Non-compliance cost:

Non-compliance cost = Actual effort - Predicted effort

To calculate the actual effort, we need to sum up the effort for each component mentioned:

Actual effort = Plan development + Software development + Reviews + Tests + Training + Methodology

Actual effort = 25 + 75 + 20 + 30 + 20 + 5 = 175 d/p

Non-compliance cost = Actual effort - Predicted effort = 175 - 250 = -75 d/p

Enforcement cost:

Enforcement cost = Non-compliance cost * Cost per person-day

Assuming a cost of $100 per person-day, we can calculate the enforcement cost:

Enforcement cost = -75 * $100 = -$7500 (negative value indicates a cost reduction due to underestimation)

Prevention cost:

Prevention cost = Predicted effort * Cost per person-day

Assuming a cost of $100 per person-day, we can calculate the prevention cost for each component:

Plan development prevention cost = 25 * $100 = $2500

Software development prevention cost = 75 * $100 = $7500

Reviews prevention cost = 20 * $100 = $2000

Tests prevention cost = 30 * $100 = $3000

Training prevention cost = 20 * $100 = $2000

Methodology prevention cost = 5 * $100 = $500

Total prevention cost = Sum of prevention costs = $2500 + $7500 + $2000 + $3000 + $2000 + $500 = $17500

Evaluation cost:

Evaluation cost = Total project cost - Prevention cost - Enforcement cost

Evaluation cost = $25000 - $17500 - (-$7500) = $5000

b) To calculate the percentage of effort devoted to each component out of the total cost, we can use the following formula:

Percentage of effort = (Effort for a component / Total project cost) * 100

Percentage of effort for each component:

Plan development = (25 / 250) * 100 = 10%

Software development = (75 / 250) * 100 = 30%

Reviews = (20 / 250) * 100 = 8%

Tests = (30 / 250) * 100 = 12%

Training = (20 / 250) * 100 = 8%

Methodology = (5 / 250) * 100 = 2%

Answer:

critical number: 26.6667

increasing from (-∞, 26.6667) and decreasing from (26.6667,∞)

Step-by-step explanation:

1) find the derivative:

derivative of f(x) = 16-0.6x

2) Set derivative equal to zero

16-0.6x = 0

0.6x = 16

x = 26.6667

3) Create a table of intervals

(-∞, 26.6667) | (26.6667, ∞)

          1                     27

Plug in these numbers into the derivative

         +                      -

So It is increasing from (-∞, 26.6667) and decreasing from (26.6667,∞)

The derivative of g(x) w.r.t. x is -1/x², determined by point to point with help of differential quotient .

Here, f(x) = (2x)*∴ f(x) = 2x¹ ∙

Differentiating f(x) with respect to x, we have;

f'(x) = d/dx(2x) ₓ f'(x)

= (d/dx)(2x¹ ∙)

[Using the Power rule of differentiation]

f'(x) = 2∙*∙x¹⁻¹ [Differentiating (2x¹∙) w.r.t. x]

= 2 ₓ x⁰ = 2∙.

Therefore, the derivative of f(x) w.r.t. x is .

(b) g: R: {0} → R mit g(x)

Here, g(x) = √x, x > 0∴ g(x) = x^(1/2)

Differentiating g(x) with respect to x, we have;g'(x) = d/dx(x^(1/2))g'(x)

= (d/dx)(x^(1/2)) [Using the Power rule of differentiation]

g'(x) = (1/2)∙x^(-1/2) [Differentiating (x^(1/2)) w.r.t. x]= 1/(2∙√x).

Therefore, the derivative of g(x) w.r.t. x is 1/(2∙√x).

Aufgabe A.10.2 (Central differential quotient)

Let f: 1 → R be differentiable in xo E I.

prove that (x+1/x)² lim f(xo+h)-f(xo-1)= • f'(xo).

2/1 1-0 :   We have to prove that,lim(x → 0) (f(xo + h) - f(xo - h))/2h = f'(xo).

Here, given that (x + 1/x)² Let f(x) = (x + 1/x)², then we have to prove that,(x + 1/x)² lim(x → 0) [f(xo + h) - f(xo - h)]/2h = f'(xo).

Differentiating f(x) with respect to x, we have;f(x) = (x + 1/x)²

f'(x)  = d/dx[(x + 1/x)² ]f'(x) = 2(x + 1/x)[d/dx(x + 1/x)] [Using the Chain rule of differentiation]f'(x) = 2(x + 1/x)(1 - 1/x² )

[Differentiating (x + 1/x) w.r.t. x]= 2[(x² + 1)/x²]

[Simplifying the above expression]

Therefore, the value of f'(x) is 2[(x² + 1)/x² ].

Now, we can substitute xo + h and xo - h in place of x.

Thus, we get;lim(x → 0) [f(xo + h) - f(xo - h)]/2h= lim(x → 0)

[(xo + h + 1/(xo + h))² - (xo - h + 1/(xo - h))² ]/2h

[Substituting xo + h and xo - h in place of x in f(x)]

On simplifying,lim(x → 0) [f(xo + h) - f(xo - h)]/2h

= lim(x → 0) 4(h/xo³) {xo² + h² + 1 + xo²h²}/2h

= lim(x → 0) 4(xo²h²/xo³) {1 + (h/xo)² + (1/xo²)}/2h

= lim(x → 0) 4h(xo² + h² )/xo³ (xo² h ²)

[On simplifying the above expression]= 2/xo

= f'(xo).

Hence, the given statement is proved.

Aufgabe A.10.3 (Differentiability)(a) f: Ro R, f(x) = √x

Given, f(x) = √x

Differentiating f(x) with respect to x, we have;f'(x) = d/dx(√x)f'(x) = 1/2√x [Using the Chain rule of differentiation]

Therefore, the derivative of f(x) w.r.t. x is 1/2√x.(b) g: Ro R, g(x) = 1/x

Given, g(x) = 1/x

Differentiating g(x) with respect to x, we have;g'(x) = d/dx(1/x)g'(x) = -1/x²

[Using the Chain rule of differentiation]

Therefore, the derivative of g(x) w.r.t. x is -1/x².

The probability of getting all four questions correct is 1/16.

To determine the probability of getting all four questions correct, we need to consider the number of favorable outcomes (getting all answers correct) and the total number of possible outcomes.

For each multiple-choice question, there are 4 answer choices, and only 1 is correct. Thus, the probability of getting both multiple-choice questions correct is (1/4) * (1/4) = 1/16.

For true or false questions, there are 2 possible answers (true or false) for each question. The probability of getting both true or false questions correct is (1/2) * (1/2) = 1/4.

To find the overall probability of getting all four questions correct, we multiply the probabilities of each type of question: (1/16) * (1/4) = 1/64.

Therefore, the probability of getting all four questions correct is 1/64.

The given expression is: ax² + 9x1 = 0

The solution for the quadratic equation is given as:x = -b ± sqrt(b² - 4ac) / 2a

Let's substitute the given values of the expression to solve for x:x = -9 ± sqrt(9² - 4a × a × 1) / 2a = -9 ± sqrt(81 - 4a²) / 2a

The range of possible values for a can be found by determining the discriminant: b² - 4ac = 81 - 4a²

Since the discriminant cannot be negative (square root of a negative value does not exist), therefore:b² - 4ac ≥ 0 ⇒ 81 - 4a² ≥ 0 ⇒ a² ≤ 20.25

So, the possible range of values of a is:-√20.25 ≤ a ≤ √20.25 or -4.5 ≤ a ≤ 4.5.
