b) sin(x^2 + y^2)/ x^2 + y^2, as (x,y) → (0,0).

To find F'(8), we need to differentiate the function F(x) = f(f(x)) using the chain rule. Let's denote f(x) as y for simplicity. So we have F(x) = f(f(x)) = f(y).

Using the chain rule, we can express F'(x) as F'(x) = f'(y) * f'(x).

Given that f(8) = 2 and f'(8) = 8, we substitute y = 2 into the expression:

F'(8) = f'(2) * f'(8).

Given that f(2) = 2 and f'(2) = 6, we substitute these values into the expression:

F'(8) = 6 * 8 = 48.

Therefore, F'(8) = 48.

To find G'(8), we differentiate the function G(x) =[tex](F(x))^2[/tex] using the chain rule.

Let's denote F(x) as z for simplicity. So we have G(x) = [tex](z)^2[/tex].

Using the chain rule, we can express G'(x) as [tex]G'(x) = 2zF'(x)[/tex].

Substituting F(x) = f(f(x)) and F'(x) = f'(f(x)) * f'(x) into the expression, we have:

[tex]G'(x) = 2f(f(x))f'(f(x))f'(x)[/tex].

Given that f(8) = 2 and f'(8) = 8, we substitute these values into the expression:

[tex]G'(8) = 2f(f(8))f'(f(8))f'(8)[/tex].

Since f(8) = 2 and f'(8) = 8, we have:

[tex]G'(8) = 2f(2)f'(2)8[/tex].

Substituting f(2) = 2 and f'(2) = 6 into the expression, we get:

[tex]G'(8) &= 2 \cdot 2 \cdot 6 \cdot 8 \\\\&= \boxed{192}[/tex]

Therefore, G'(8) = 192.

The general solution for the differential equation y′′−4y′+4y=0, with initial conditions y(0)=2 and y′(0)=4, is y(x) = (2 + 2x)e^(2x).

To find the general solution of the given differential equation, we can assume that y(x) can be expressed as a power series, y(x) = Σ(a_nx^n), where a_n are constants to be determined. Differentiating y(x), we get y′(x) = Σ(na_nx^(n-1)) and y′′(x) = Σ(n(n-1)a_nx^(n-2)). Substituting these expressions into the differential equation, we obtain the power series Σ(n(n-1)a_nx^(n-2)) - 4Σ(na_nx^(n-1)) + 4Σ(a_nx^n) = 0. Simplifying the equation and setting the coefficients of each power of x to zero, we find that a_n = (n+2)a_(n+2)/(n(n-1)-4n) for n ≥ 2. Using this recursive relationship, we can determine the values of a_n for any desired term in the power series.

Given the initial conditions y(0)=2 and y′(0)=4, we can substitute these values into the power series representation of y(x) and solve for the constants. By doing so, we find that a_0 = 2, a_1 = 6, and all other coefficients are zero. Thus, the general solution is y(x) = (2 + 2x)e^(2x), which satisfies the given differential equation and initial conditions.

The maximum of the function f(x,y)=6xy−x ^2+3y ^2

subject to the constraint is achieved at specific values of x and y.

The value of x at the constrained maximum: 2

The value of y at the constrained maximum: 2

The function value at the constrained maximum: 12

To find the constrained maximum, we need to optimize the objective function while satisfying the constraint. In this case, we have the function

f(x,y)=6xy−x ^2+3y ^2 and the constraint  x+y=4.

To proceed, we can use the method of Lagrange multipliers, which involves introducing a Lagrange multiplier, λ, to incorporate the constraint into the objective function. We form the Lagrangian function L(x, y, λ) as  L(x,y,λ)=f(x,y)−λ(x+y−4).

Next, we differentiate L(x, y, λ) with respect to x, y, and λ, and set the partial derivatives equal to zero to find critical points. Solving these equations, we obtain the values x = 2, y = 2, and λ = -2.

To determine if this critical point is a maximum, minimum, or saddle point, we evaluate the second-order partial derivatives of L(x, y, λ). After performing the calculations, we find that the second-order partial derivative test confirms that this critical point represents a maximum.

Hence, the maximum value of the function  is achieved at x = 2, y = 2, with a function value of 12.

We have complex conjugate poles and a single zero, the root locus will start at the poles and terminate at the zero. The branches will follow the asymptotes' angles, and the behaviour around the poles will depend on the gain K.

To draw the root locus of the given open-loop transfer function (O.L.T.F.) G(s) = (s+1) / (s^2(s^2+6s+12)), we need to determine the poles and zeros of the system and analyze their locations to understand the stability.

Step 1: Poles and Zeros

The transfer function G(s) has the following poles and zeros:

Zeros: s = -1 (single zero at -1)

Poles: s = 0 (double pole at 0), s = -3 ± j (complex conjugate poles)

Step 2: Number of branches and asymptotes

The root locus consists of the branches of the system poles as the gain K varies. The number of branches is equal to the number of poles, which is 4 in this case. Additionally, there are asymptotes that provide an approximation of the root locus behaviour.

The number of asymptotes is given by the formula: N = P - Z, where P is the number of poles and Z is the number of zeros. In this case, N = 4 - 1 = 3, so there will be three asymptotes.

Step 3: Asymptotes angles and centers

The angles of the asymptotes are given by the formula: θ = (2k + 1)π / N, where k = 0, 1, 2, ..., N-1.

For N = 3, we have three asymptotes with angles:

θ1 = π/3, θ2 = π, θ3 = 5π/3

The centers of the asymptotes can be calculated using the formula: σ = (Σpoles - Σzeros) / N, where σ is the real part of the asymptote center.

The sum of poles (Σpoles) = 0 + (-3) + (-3) = -6

The sum of zeros (Σzeros) = -1

So, the center of the asymptotes is:

σ = (-6 - (-1)) / 3 = -5/3

Step 4: Breakaway and break-in points

To find the breakaway and break-in points, we need to determine the values of s where the denominator of the characteristic equation becomes zero. The characteristic equation is obtained by setting the denominator of the transfer function equal to zero:

s^2 + 6s + 12 = 0

Using the quadratic formula, we find the roots of this equation:

s = (-6 ± √(6^2 - 4*1*12)) / (2*1)

s = (-6 ± √(36 - 48)) / 2

s = (-6 ± √(-12)) / 2

s = (-6 ± √(12)i) / 2

s = -3 ± √(3)i

Therefore, the breakaway and break-in points occur at s = -3 + √(3)i and s = -3 - √(3)i.

Step 5: Sketching the root locus

Using the information obtained from the previous steps, we can sketch the root locus by considering the branches, asymptotes, breakaway and break-in points, and the behaviour around the poles.

Given that we have complex conjugate poles and a single zero, the root locus will start at the poles and terminate at the zero. The branches will follow the asymptotes' angles, and the behaviour around the poles will depend on the gain K.

The average rate of change of the function h(t) = cot(t) over the interval [3π/4, 5π/4] is zero.

To find the average rate of change of a function over an interval, we need to calculate the difference in the function values at the endpoints of the interval and divide it by the length of the interval.
In this case, the function is h(t) = cot(t), and the interval is [3π/4, 5π/4].
At the left endpoint, t = 3π/4:
h(3π/4) = cot(3π/4) = 1/tan(3π/4) = 1/(-1) = -1
At the right endpoint, t = 5π/4:
h(5π/4) = cot(5π/4) = 1/tan(5π/4) = 1/(-1) = -1
The difference in function values is:
h(5π/4) - h(3π/4) = -1 - (-1) = 0
The length of the interval is:
5π/4 - 3π/4 = 2π/4 = π/2
Finally, we calculate the average rate of change:
Average rate of change = (h(5π/4) - h(3π/4)) / (5π/4 - 3π/4) = 0 / (π/2) = 0
Therefore, the average rate of change of the function h(t) = cot(t) over the interval [3π/4, 5π/4] is zero.

It is correct to say that measurements are affected by both bias and chance error, as these factors contribute to the overall uncertainty and variability in the measurement process.

Measurements are typically affected by both bias and chance error. Bias refers to a systematic error or tendency for measurements to consistently deviate from the true value in the same direction. It can be caused by various factors such as calibration issues, instrument inaccuracies, or human error. Bias affects the accuracy of measurements by introducing a consistent deviation from the true value.

On the other hand, chance error, also known as random error, is the variability or inconsistency in measurements that occurs due to unpredictable factors. These factors can include environmental conditions, variations in measurement techniques, or inherent limitations of the measuring instruments. Chance error leads to fluctuations in measurement values around the true value and affects the precision of measurements.

Therefore, it is correct to say that measurements are affected by both bias and chance error, as these factors contribute to the overall uncertainty and variability in the measurement process.

To calculate the total angle the tires rotate through during the boy's trip, we can use the formula:

\[

\theta = \frac{{\text{{distance traveled}}}}{{\text{{circumference of the wheel}}}}

\]

First, let's convert the distance traveled from kilometers to centimeters, as the radius of the wheels is given in centimeters. Since 1 kilometer is equal to 100,000 centimeters, the distance traveled is \(1.5 \mathrm{~km} = 1.5 \times 100,000 \mathrm{~cm} = 150,000 \mathrm{~cm}\).

The circumference of a circle can be calculated using the formula \(C = 2 \pi r\), where \(r\) is the radius of the wheel. Substituting the given radius value, we have \(C = 2 \pi \times 30.0 \mathrm{~cm} = 60 \pi \mathrm{~cm}\).

Now, let's calculate the angle:

\[

\theta = \frac{{150,000 \mathrm{~cm}}}{{60 \pi \mathrm{~cm}}} = \frac{{2,500}}{{\pi}} \mathrm{~radians} \approx 795.77 \mathrm{~radians}

Therefore, the total angle the tires rotate through during the boy's trip is approximate \(795.77\) radians.

The average cost function C(x) can be found by integrating the marginal average cost function C'(x). Using the given derivative C'(x) = -1,700/x^2, we integrate with respect to x to find C(x):

C(x) = ∫(-1,700/x^2) dx = 1,700/x + C

To determine the constant of integration C, we use the given information that C(100) = 28:

28 = 1,700/100 + C

28 = 17 + C

C = 28 - 17

C = 11

Thus, the average cost function is C(x) = 1,700/x + 11.

To find the cost function C(x), we integrate the average cost function C(x) with respect to x:

C(x) = ∫(1,700/x + 11) dx = 1,700 ln|x| + 11x + K

The constant of integration K represents the fixed costs. To determine the value of K, we can use the given information that C(100) = 28:

28 = 1,700 ln|100| + 11(100) + K

28 = 1,700 ln(100) + 1,100 + K

28 = 1,700(4.605) + 1,100 + K

28 = 7,819.5 + 1,100 + K

K = 28 - 7,819.5 - 1,100

K ≈ -8,892.5

Therefore, the cost function is C(x) = 1,700 ln|x| + 11x - 8,892.5, and the fixed costs are approximately $8,892.50.

We can sum these individual inverse Laplace transforms to obtain the inverse Laplace transform of F(s) as f(t) = Ae^(-8t) + Be^(-9t) + Ce^(3t), where A, B, and C are determined by the partial fraction decomposition.

The inverse Laplace transform of the given function F(s), we can use partial fraction decomposition.

First, we factorize the denominator: (s + 8)(s + 9)(s - 3).

Next, we express F(s) as a sum of partial fractions with undetermined coefficients:

F(s) = A/(s + 8) + B/(s + 9) + C/(s - 3).

To find the values of A, B, and C, we multiply both sides of the equation by the denominator and then equate the coefficients of the corresponding powers of s:

1 = A(s + 9)(s - 3) + B(s + 8)(s - 3) + C(s + 8)(s + 9).

By comparing coefficients, we can solve for A, B, and C. Once we have their values, we can rewrite F(s) in terms of the partial fractions.

Now, we can take the inverse Laplace transform of each term individually using known formulas from a Laplace transform table or other references. The inverse Laplace transform of A/(s + 8) is Ae^(-8t), B/(s + 9) is Be^(-9t), and C/(s - 3) is Ce^(3t).

Finally, we can sum these individual inverse Laplace transforms to obtain the inverse Laplace transform of F(s) as f(t) = Ae^(-8t) + Be^(-9t) + Ce^(3t), where A, B, and C are determined by the partial fraction decomposition.

a) Signal \(y_1(t) = 3x(t)\) represents an amplification of the input signal \(x(t)\) by a factor of 3. b) Signal \(y_2(t) = -x(t) - 2\) represents a reflection and vertical shift of the input signal \(x(t)\).

a) To obtain \(y_1(t)\), we multiply each value of the input signal \(x(t)\) by 3. This results in amplifying the amplitude of the input signal without any change in the shape or timing. The plot of \(y_1(t)\) will look similar to \(x(t)\), but with a higher amplitude.

b) To obtain \(y_2(t)\), we multiply the input signal \(x(t)\) by -1 to reflect it across the x-axis, and then subtract 2 from each value. This reflects the waveform vertically and shifts it downward by 2 units. The plot of \(y_2(t)\) will have the opposite amplitude and a vertical shift compared to \(x(t)\).

c) To obtain \(y_3(t)\), we introduce a time compression factor of 3 by replacing \(t\) with \(-3t - 3\) in the input signal \(x(t)\). Additionally, we add 1 to each value to shift the waveform vertically. The plot of \(y_3(t)\) will show a compressed and horizontally shifted version of \(x(t)\), along with a vertical shift.

The indefinite integral of ∫(x^4 * e^(x) - 8x^3) / x^4 dx can be evaluated by splitting it into two separate integrals and applying the power rule and the constant multiple rule of integration.

∫(x^4 * e^(x) - 8x^3) / x^4 dx = ∫(e^(x) - 8x^3 / x^4) dx

The first integral, ∫e^(x) dx, is simply e^(x) + C1, where C1 is the constant of integration.

For the second integral, we can simplify it as follows:

∫(-8x^3 / x^4) dx = -8 ∫(1 / x) dx = -8 ln|x| + C2, where C2 is another constant of integration.

Combining the results:

∫(x^4 * e^(x) - 8x^3) / x^4 dx = e^(x) - 8 ln|x| + C, where C represents the constant of integration.

A) The third fundamental form of a differentiable surface is a mathematical concept that characterizes the intrinsic geometry of the surface. It is defined in terms of the second derivatives of the surface's parameterization. Geometrically, the third fundamental form measures the rate of change of the surface's unit normal vector as one moves in the direction of the surface.

Proof:

The third fundamental form, denoted as III, is given by the equation:

III = -N · (d²r/du²) · (d²r/dv²) / |dr/du × dr/dv|,

where N is the unit normal vector to the surface, r(u, v) is the parameterization of the surface, and d²r/du² and d²r/dv² are the second derivatives of r with respect to u and v, respectively. |dr/du × dr/dv| represents the magnitude of the cross product of the partial derivatives of r.

B) The properties of the third fundamental form include:

1. Invariance under reparameterization: The third fundamental form is invariant under changes in the parameterization of the surface. This property ensures that the geometric information encoded by the third fundamental form remains consistent regardless of how the surface is parameterized.

2. Symmetry: The third fundamental form is symmetric with respect to the two variables u and v. In other words, swapping the roles of u and v does not change the value of the third fundamental form.

3. Relationship with the second fundamental form: The third fundamental form is related to the second fundamental form, which characterizes the extrinsic curvature of the surface. More specifically, the third fundamental form is expressed in terms of the second fundamental form as:

III = -N · L,

where L is the linear operator defined as:

L = (d²r/dv²) · S · (d²r/du²) - (d²r/dv²) · S · (d²r/dv²),

and S is the shape operator associated with the surface.

The proofs for these properties involve calculations using the definition and properties of the second fundamental form, as well as manipulation of the differential operators. These proofs require a more detailed understanding of differential geometry and are beyond the scope of this brief explanation.

The derivative y' using implicit differentiation for the equation x^2 - 4xy + y^2 = 4 is given by:y' = (4y - 2x) / (2y - 4x)

To find y' using implicit differentiation for the equation x^2 - 4xy + y^2 = 4, we differentiate both sides of the equation with respect to x.

Differentiating the left side of the equation requires the application of the chain rule.

Differentiating x^2 with respect to x gives 2x.

Differentiating -4xy with respect to x gives -4y - 4x(dy/dx), using the product rule.

Differentiating y^2 with respect to x gives 2y(dy/dx), again using the chain rule.

Therefore, the derivative of the left side of the equation is 2x - 4y - 4x(dy/dx) + 2y(dy/dx).

Differentiating the right side of the equation with respect to x gives 0, since 4 is a constant.

Now, we can rewrite the equation with the derivatives:

2x - 4y - 4x(dy/dx) + 2y(dy/dx) = 0

Next, we can rearrange the equation to solve for dy/dx:

-4x(dy/dx) + 2y(dy/dx) = 4y - 2x

Factor out dy/dx:

(2y - 4x)(dy/dx) = 4y - 2x

Divide both sides by (2y - 4x):

dy/dx = (4y - 2x) / (2y - 4x)

Hence, the derivative y' using implicit differentiation for the equation x^2 - 4xy + y^2 = 4 is given by:

y' = (4y - 2x) / (2y - 4x)

By the end of week 52, Westway Company deducted $8,857.60 for Social Security and $2,426.48 for Medicare from Suzle Chan's earnings.

To calculate the deductions made by Westway Company, we'll need to consider the Social Security and Medicare taxes.

Social Security tax:

The Social Security tax rate is 6.2% on income up to $142,800.

Since Suzle Chan earns $3,220 per week, their annual income is $3,220 * 52 = $167,440.

However, the maximum taxable income for Social Security is $142,800.

Therefore, the Social Security tax deduction is $142,800 * 0.062 = $8,857.60.

Medicare tax:

The Medicare tax rate is 1.45% on all income.

The Medicare tax deduction is $167,440 * 0.0145 = $2,426.48.

[tex]g(x) = -3x^3 + 2[/tex] and

[tex]f(x) = cos(x)^3f'(x)[/tex]

[tex]= 3cos(x)^2 * (-sin(x))[/tex]

To determine the probability of selecting a ball with a specific number, we need to know the total number of balls in the urn. From the given information, we have 6 black balls and 8 white balls, making a total of 14 balls in the urn.

(a) Probability of selecting a specific number:

Let's assume we want to find the probability of selecting the ball with a specific number, say "3".

The number of balls with "3" is 2 (one black and one white). Therefore, the probability of selecting the ball numbered "3" is given by:

\[ P(\text{number 3}) = \frac{\text{number of balls with 3}}{\text{total number of balls}} = \frac{2}{14} \]

Simplifying the fraction, we have:

\[ P(\text{number 3}) = \frac{1}{7} \]

So, the probability of selecting the ball numbered "3" is \( \frac{1}{7} \).

To find the distance between the skew lines with the given parametric equations, we can use the formula for the distance between two skew lines in three-dimensional space. By applying the formula, the distance between the skew lines is found to be √37.

The formula for the distance between two skew lines with parametric equations is given by d = √((PQ)² / ||v × w||²), where PQ is the vector connecting a point on one line to the other line, v is the direction vector of the first line, and w is the direction vector of the second line.

For the given lines, the direction vectors are v = ⟨1, 6, 2⟩ and w = ⟨2, 14, 5⟩. To find the vector PQ, we can take any point on one line (let's choose the point (3, 2, 0)) and subtract the coordinates from a point on the other line (let's choose the point (2, 6, -3)):

PQ = ⟨2 - 3, 6 - 2, -3 - 0⟩ = ⟨-1, 4, -3⟩

Next, we calculate the cross product of v and w:

v × w = ⟨1, 6, 2⟩ × ⟨2, 14, 5⟩ = ⟨-2, -9, 8⟩

Now, we can substitute these values into the formula for the distance:

d = √((-1, 4, -3) · (-1, 4, -3)) / ||⟨-2, -9, 8⟩||²)

 = √(1 + 16 + 9) / (4 + 81 + 64)

The answer for the given question ∫(4x^2+ 1)^3/2 dx is 1/4 (4x^2 + 1)^5/2 + C.

The given integral is ∫1 /√(x^2-4x+8) dx.

Step 1: Completing the square:

x^2 - 4x + 8 = 0

Add and subtract 4 to the left side of the equation:

x^2 - 4x + 4 + 4 = 0

x^2 - 4x + 4 = -4

We know that (a-b)^2 = a^2 - 2ab + b^2, so:

(x - 2)^2 - 4 = -4

(x - 2)^2 = 8

(x - 2)^2 = 8 + 4

(x - 2)^2 = 12

x - 2 = ±2√3

(x - 2) = 2 ± 2√3

x = 2 ± 2√3

Step 2: Making an appropriate trigonometric substitution:

Let x = 2 + 2√3 tan θ, then dx = 2√3 sec^2θ dθ

When x = 2, θ = π/3

When x = 2 + 2√3, θ = π/2

Then ∫1/√(x^2 - 4x + 8)dx = ∫secθ × 2√3 sec^2θ dθ

= 2√3 ∫ sec^3θ dθ

Integrating by parts:

u = secθ and dv = sec^2θ

du/dθ = secθ tanθ

v = tanθ

= secθ tanθ - ∫ tan^2θ secθ dθ

= secθ tanθ - ∫secθ dθ + ∫1 dθ

= secθ tanθ - ln|secθ + tanθ| + C

Thus, ∫1 /√(x^2-4x+8) dx = 2√3 (secθ tanθ - ln|secθ + tanθ|) + C

Now let us integrate ∫(4x^2+ 1)^3/2 dx. Notice that 4x^2 + 1 = (2x)^2 + 1 and that (4x^2 + 1)^3/2 = (√(4x^2 + 1)^3

Let u = 4x^2 + 1 and du/dx = 8x. dx = du/8x.

∫(4x^2+ 1)^3/2 dx = 1/8 ∫u^3/2 du

= 1/8 × 2/5(u^5/2) + C

= 1/4 u^5/2 + C

= 1/4 (4x^2 + 1)^5/2 + C

The final answer for the given question ∫1 /√(x^2-4x+8) dx is 2√3 (secθ tanθ - ln|secθ + tanθ|) + C, and the final answer for the given question ∫(4x^2+ 1)^3/2 dx is 1/4 (4x^2 + 1)^5/2 + C.
