The arc length of the curve defined by r(t) = [tex]\sin(t)i + \cos(t)j + tk\)[/tex]for [tex]\(0 \leq t \leq 2\pi\) is \(2\pi\sqrt{2}\)[/tex] units.

The arc length of a curve measures the distance along the curve from one point to another. In this case, we have a parametric equation r(t) that defines a curve in three-dimensional space. To find the arc length, we need to integrate the magnitude of the velocity vector, which represents the rate of change of position. The velocity vector is given by [tex]\(\vec{v}(t) = \frac{d\vec{r}}{dt} = \cos(t)i - \sin(t)j + k\).[/tex] Taking the magnitude of this vector, we get [tex]\(\|\vec{v}(t)\| = \sqrt{(\cos(t))^2 + (-\sin(t))^2 + 1^2} = \sqrt{2}\)[/tex].

Integrating the magnitude of the velocity vector from [tex]\(t = 0\) to \(t = 2\pi\)[/tex], we have:

[tex]\[s = \int_0^{2\pi} \|\vec{v}(t)\| dt = \int_0^{2\pi} \sqrt{2} dt = \sqrt{2} \cdot t \Big|_0^{2\pi} = \sqrt{2} \cdot 2\pi = 2\pi\sqrt{2}.\][/tex]

Therefore, the arc length of the curve r(t) for [tex]\(0 \leq t \leq 2\pi\) is \(2\pi\sqrt{2}\)[/tex] units.

The expected value of x is 7/3.

The probability function of a random variable can be used to find the expected value of the random variable.

In this case, x is a random variable with the probability function: f(x) = x/6 for x = 1,2, or 3.

The expected value of x can be found using the formula:

E(X) = Σ[x * f(x)]For the given probability function, we can find the expected value of x as follows:

E(X) = (1 * f(1)) + (2 * f(2)) + (3 * f(3))Here, f(1) = 1/6, f(2) = 2/6 = 1/3, and f(3) = 3/6 = 1/2.

Substituting these values, we get:

E(X) = (1 * 1/6) + (2 * 1/3) + (3 * 1/2)= 1/6 + 2/3 + 3/2= 1/6 + 4/6 + 9/6= 14/6= 7/3

The area under the graph of f over the interval [3,9] is 149



To find the area under the graph of the function f over the interval [3,9], we need to split the interval into two parts: [3,7] and (7,9]. In the first part, the function is given by f(x) = 2x + 7, and in the second part, it is given by f(x) = 56 - (5/2)x.

First, let's calculate the area under the graph of f(x) = 2x + 7 over the interval [3,7]. We can find the definite integral of 2x + 7 with respect to x:

∫[3 to 7] (2x + 7) dx = [x^2 + 7x] evaluated from 3 to 7.

Substituting the upper and lower limits into the integral, we get:

[(7^2 + 7(7)) - (3^2 + 7(3))] = (49 + 49) - (9 + 21) = 98 - 30 = 68.

Next, let's calculate the area under the graph of f(x) = 56 - (5/2)x over the interval (7,9]. We can find the definite integral of 56 - (5/2)x with respect to x:

∫[7 to 9] (56 - (5/2)x) dx = [56x - (5/4)x^2] evaluated from 7 to 9.

Substituting the upper and lower limits into the integral, we get:

[(56(9) - (5/4)(9^2)) - (56(7) - (5/4)(7^2))] = (504 - 202.5) - (392 - 171.5) = 301.5 - 220.5 = 81.

Finally, to find the total area under the graph of f over the interval [3,9], we sum up the areas from both parts:

Total area = Area from [3 to 7] + Area from (7 to 9] = 68 + 81 = 149.

Therefore, the area under the graph of f over the interval [3,9] is 149.

The area enclosed by the curve y = 1/(1 + 3x) above the x-axis between the lines x = 2 and x = 3 is (1/3) ln(4/7).

To find the area enclosed by the curve y = 1/(1 + 3x) above the x-axis between the lines x = 2 and x = 3, we can calculate the definite integral of the function within the given interval.

The definite integral for the area can be expressed as:

A = ∫[2, 3] (1/(1 + 3x)) dx

To solve this integral, we can use the substitution method. Let u = 1 + 3x, then du = 3 dx. Rearranging the equation, we have dx = du/3.

Substituting the values, the integral becomes:

A = ∫[2, 3] (1/u) (du/3)

A = (1/3) ∫[2, 3] du/u

A = (1/3) ln|u| |[2, 3]

Now, substituting back u = 1 + 3x, we have:

A = (1/3) ln|1 + 3x| |[2, 3]

Evaluating the integral within the given limits, we get:

A = (1/3) ln|4| - (1/3) ln|7|

Simplifying further, we have:

A = (1/3) ln(4/7)

The maximum volume of the box is approximately 79.63 cubic inches. Given that a piece of cardboard measuring 9 inches by 12 inches is formed into an open-top box by cutting squares with side length x from each corner and folding up the sides. We need to find the following.

a. Formula for the volume of the box in terms of x.b. The value for x that will maximize the volume of the box. c. Determine the maximum volume.

b. Volume V(x)

Volume of the box = length × width × height

When we fold up the sides, we get height = x

Length of the base of the box = 9 - 2x

Width of the base of the box

= 12 - 2x

Therefore, the volume of the box is given byV(x) = (9 - 2x)(12 - 2x)x

We can simplify this expression by multiplying:

x(108 - 42x + 4x²)V(x) = 4x³ - 42x² + 108x

Thus, the formula for the volume of the box in terms of x is given by V(x) = 4x³ - 42x² + 108x

b. Value for x that will maximize the volume of the box

To find the value of x that will maximize the volume of the box, we need to find the derivative of the volume function and set it equal to zero.

V(x) = 4x³ - 42x² + 108x

Differentiating with respect to x, we get:V'(x) = 12x² - 84x + 108

Setting V'(x) = 0, we get:

12x² - 84x + 108 = 0

Dividing both sides by 12, we get:x² - 7x + 9 = 0Solving for x using the quadratic formula,

we get:x = [7 ± sqrt(7² - 4(1)(9))]/2x

= [7 ± sqrt(37)]/2x

≈ 1.47 or

x ≈ 5.53

Since x cannot be greater than 4.5 (half of the width or length of the cardboard), the value of x that maximizes the volume of the box is approximately x ≈ 1.47 inches.

c. Maximum volumeThe maximum volume of the box can be found by plugging in the value of x that maximizes the volume into the volume function:V(x) = 4x³ - 42x² + 108xV(1.47) ≈ 79.63

Therefore, the maximum volume of the box is approximately 79.63 cubic inches (rounded to two decimal places).

P(A₁, A₂, A₃, F₁, F₂, F₃, F₄)

(iii) To describe the joint probability distribution, we need to specify the conditional probabilities for each node given its parents. Since all random variables are binary, each conditional probability requires only one value (probability) to describe it. Therefore, the number of parameters required to describe this joint probability distribution can be calculated as follows:

Number of parameters = Number of conditional probabilities

In this Bayesian network, there are seven nodes: A₁, A₂, A₃, F₁, F₂, F₃, and F₄. Hence, the number of parameters required is 7.

(iv) If we observe that F₂ is true, it tells us that there is a higher probability of cyber attack A₁ being present because F₂ depends on A₁. However, observing F₄ being true does not provide any additional information about the type of cyber attack because F₄ depends only on A₃, and there is no direct dependence between A₁ and A₃.

If we observe that F₃ is true instead of F₂, it tells us that there is a higher probability of cyber attack A₁ and A₃ being present because F₃ depends on both A₁ and A₃. Similar to before, observing F₄ being true does not provide any additional information about the type of cyber attack because F₄ depends only on A₃.

The inverse function is f⁻¹(x) = [(x + 5)^(4/3) - 1]², and we can show that (f⁻¹of)(x) = x by substituting f⁻¹(x) into the expression.

In the given problem, we are asked to find the inverse function of f(x) = 3√√x+1-5 and then show that (f⁻¹of)(x) = x.

(a) To find the inverse function f⁻¹(x), we interchange x and f(x) and solve for x:

x = 3√√f(x)+1-5

First, add 5 to both sides:

x + 5 = 3√√f(x)+1

Next, raise both sides to the power of 2/3:

(x + 5)^(2/3) = √√f(x)+1

Finally, raise both sides to the power of 2:

[(x + 5)^(2/3)]^2 = √f(x) + 1

Simplify:

(x + 5)^(4/3) - 1 = √f(x)

Square both sides:

[(x + 5)^(4/3) - 1]^2 = f(x)

Therefore, f⁻¹(x) = [(x + 5)^(4/3) - 1]^2.

(b) To show that (f⁻¹of)(x) = x, we substitute f⁻¹(x) into the expression:

(f⁻¹of)(x) = [(x + 5)^(4/3) - 1]^2

Expanding and simplifying the expression, we can verify that it is equal to x.

Thus, we have found the inverse function f⁻¹(x) and shown that (f⁻¹of)(x) = x, as required.

The general solution is [tex]y = -1/(3x^2) + Cx,[/tex] and the specific solution with the initial condition y(0) = 1 cannot be determined without additional information.

To find the general solution to the differential equation [tex]x(dy/dx) - y = 1/x^2[/tex], we can use the method of integrating factors.

First, let's rewrite the differential equation in the standard form:

[tex]dy/dx + (-1/x) * y = 1/(x^3)[/tex]

The integrating factor (IF) can be found by taking the exponential of the integral of (-1/x) with respect to x:

IF = [tex]e^{(-∫(1/x) dx)[/tex]

= [tex]e^{(-ln|x|)[/tex]

= 1/x

Multiplying both sides of the differential equation by the integrating factor:

[tex](1/x) * (dy/dx) + (-1/x^2) * y = 1/(x^3) * (1/x)[/tex]

Simplifying:

[tex](1/x) * (dy/dx) - y/x^2 = 1/x^4[/tex]

Now, notice that the left side is the derivative of (y/x):

[tex]d/dx (y/x) = 1/x^4[/tex]

Integrating both sides with respect to x:

[tex]∫d/dx (y/x) dx = ∫(1/x^4) dx[/tex]

[tex]y/x = -1/(3x^3) + C[/tex]

Multiplying both sides by x:

[tex]y = -1/(3x^2) + Cx[/tex]

So, the general solution to the differential equation is[tex]y = -1/(3x^2) + Cx,[/tex]where C is an arbitrary constant.

Now, let's solve the differential equation[tex]dy/dx + y = 4x^e[/tex] given that when x = 0, y = 1.

First, we rewrite the equation in the standard form:

[tex]dy/dx + y = 4x^e[/tex]

The integrating factor (IF) can be found by taking the exponential of the integral of 1 dx:

IF = e∫1 dx

= [tex]e^x[/tex]

Multiplying both sides of the differential equation by the integrating factor:

[tex]e^x * (dy/dx) + e^x * y = 4x^e * e^x[/tex]

Simplifying:

[tex](d/dx)(e^x * y) = 4x^e * e^x[/tex]

Integrating both sides with respect to x:

∫[tex]d/dx (e^x * y) dx[/tex]= ∫[tex](4x^e * e^x) dx[/tex]

[tex]e^x * y[/tex] = ∫[tex](4x^e * e^x) dx[/tex]

Using the formula for integration by parts again:

∫[tex](x^(e-1) * e^x) dx[/tex] =[tex]x^(e-1) * e^x - ∫((e-1) * x^(e-2) * e^x) dx[/tex]

[tex]= x^(e-1) * e^x - (e-1) * ∫(x^(e-2) * e^x) dx[/tex]

We can continue this process of integration by parts until we reach an integral that we can solve. Eventually, the integral will reduce to a constant term. However, the exact form of the solution may be complex and cannot be easily expressed.

Given the initial condition that when x = 0, y = 1, we can substitute these values into the general solution to find the specific solution.

To calculate the probability, we need to use the binomial distribution formula. In this case, we have 28 trials (randomly selected shafts) and a success probability of 2% (0.02) since the vendor claims that no more than 2% of their shafts exceed 142 cm.

For the first question, we want none of the shafts to exceed 142 cm. So, we calculate the probability of getting 0 successes (shaft length > 142 cm) out of 28 trials.

The formula is P(X = k) = C(n, k) * p^k * (1-p)^(n-k), where C(n, k) is the binomial coefficient.

To calculate the Kullback-Leibler (KL) divergence between distributions P and Q, we can use the formula:

KL(P || Q) = Σ P(i) * log2(P(i) / Q(i))

where P(i) and Q(i) are the probabilities of the ith element in the distributions P and Q, respectively.

Given the distributions P and Q as follows:

P = [3/8, 3/16, 1/4, 3/16]

Q = [1/4, 1/4, 1/4, 1/4]

Let's calculate the KL divergence step by step:

KL(P || Q) = (3/8) * log2((3/8) / (1/4)) + (3/16) * log2((3/16) / (1/4)) + (1/4) * log2((1/4) / (1/4)) + (3/16) * log2((3/16) / (1/4))

Now, let's simplify the calculations:

KL(P || Q) = (3/8) * log2(3/2) + (3/16) * log2(3/4) + (1/4) * log2(1) + (3/16) * log2(3/4)

= (3/8) * log2(3/2) + (3/16) * log2(3/4) + (1/4) * 0 + (3/16) * log2(3/4)

= (3/8) * log2(3/2) + (3/16) * log2(3/4) + 0 + (3/16) * log2(3/4)

Now, let's substitute the value of log23 (approximately 1.585):

KL(P || Q) = (3/8) * 1.585 + (3/16) * log2(3/4) + 0 + (3/16) * log2(3/4)

Calculating further:

KL(P || Q) ≈ 0.595 + (3/16) * log2(3/4) + (3/16) * log2(3/4)

Simplifying:

KL(P || Q) ≈ 0.595 + (3/16) * (-0.415) + (3/16) * (-0.415)

Calculating:

KL(P || Q) ≈ 0.595 - 0.077 - 0.077

KL(P || Q) ≈ 0.441

The composition of goh is (2x - 1)/(2x - 4).

The domain of the function is all values of x except x = 2.

So, the domain of goh is (-∞, 2) U (2, ∞) using interval notation.

Explanation:

To find the composition of goh, you need to follow the given equation :

      g(x)=x+4/x+1

and h(x)=2x-5 to solve it.

(goh)(x) = g(h(x))

             = g(2x - 5)

Now substituting

                     h(x) = 2x - 5 in g(x) we get,

                (goh)(x) = g(h(x))

                          = g(2x - 5)

                         = (2x - 5 + 4)/(2x - 5 + 1)

                          = (2x - 1)/(2x - 4)

Thus the composition of goh is (2x - 1)/(2x - 4).

Now, let's find the domain of goh.

To find the domain of (goh)(x), you have to eliminate any x values that would make the function undefined.

Since the function has a denominator in the expression, it will be undefined when the denominator equals zero, that is;

when 2x - 4 = 0.

        (2x - 4) = 0

          ⇒ 2x = 4

           ⇒ x = 2

Therefore, the domain of the function is all values of x except x = 2.

So, the domain of goh is (-∞, 2) U (2, ∞) using interval notation.

The equation of the sequence:f(n) = -1/16n³ + 3/8n² - 11/48n + 1/2

The sequence is given as 3 2 , − 4 4 , 5 8 , − 6 16 , 7 32.

Let us examine the sequence to see if there is a pattern.

To begin, let us look at the first terms in each fraction:

3, -4, 5, -6, 7

The first differences of these terms is -7, 9, -11, 13

The second differences is 16, -20, 24.

The third differences is -36, 44.

If we examine the third differences, we can notice that the third differences are constant and equal to -36.

So the degree of the polynomial that generates the sequence is three or less.

To determine the equation that generates the sequence, we'll use the following method:

Since the sequence has degree 3 or less, we can use the general form:

f(n) = an³ + bn² + cn + d

We can use four points from the sequence to get four equations to solve for a, b, c, and d:

Let n = 1: f(1) = a + b + c + d

= 3/2

Let n = 2: f(2) = 8a + 4b + 2c + d

= -4/4

Let n = 3: f(3) = 27a + 9b + 3c + d

= 5/8

Let n = 4: f(4) = 64a + 16b + 4c + d

= -6/16

Solving these equations will give us the equation of the sequence:

To calculate the decay constant, you need to perform the linear regression analysis and find the slope of the best-fit line using the given data.

To calculate the decay constant of the given isotope using a linear fit, we can use the equation y = yo - Xt, where y represents the logarithm of the number of radioactive nuclei and t represents time. We have the following data:

t (min): 1   2   3   4
y:         7.40 7.35 7.19 6.93

We can rewrite the equation as y = mx + c, where m is the slope and c is the y-intercept. Rearranging the equation, we get X = (yo - y) / t.

Using the given data, we can calculate the values of X for each time interval:

X1 = (yo - y1) / t1 = (yo - 7.40) / 1
X2 = (yo - y2) / t2 = (yo - 7.35) / 2
X3 = (yo - y3) / t3 = (yo - 7.19) / 3
X4 = (yo - y4) / t4 = (yo - 6.93) / 4

We want to find the value of A, the decay constant, which is equal to -m (the negative slope). To find the best-fit line, we need to minimize the sum of squared errors between the observed values of X and the values predicted by the linear fit.

By performing a linear regression analysis using the data points (t, X), we can obtain the slope of the best-fit line, which will be -A. Calculating the slope using linear regression will give us the value of A.

The given linear function is:f(x) = -7.6x + 27

To find the slope of the function we have to convert it into slope-intercept form y = mx + b

where y = f(x), m = slope, and b = y-intercept

Therefore, we have f(x) = -7.6x + 27y = -7.6x + 27

We can see that the slope is -7.6, which means for every unit increase in the independent variable (x), the dependent variable (y) decreases by 7.6 units.

Hence, the rate of change of the dependent variable per unit change in the independent variable is -7.6.

To find the values of a and b for which the given system of equations has no solutions or a unique solution, we need to solve the system of equations and analyze the coefficients.

To find the values of a and b for which the given system of equations has no solutions or a unique solution, let's analyze each problem separately:

To find the values of a and b for which the system has no solutions, we need to determine when the equations become inconsistent or contradictory. Let's solve the system of equations:

Equation 1: x1 + x2 + x3 = 4 + 5x2

Equation 2: 4x3 = 16

Equation 3: 3x1 + 2x1 + 3x2 - ax3 = b

From Equation 2, we have 4x3 = 16, which gives x3 = 4. Substituting this value into Equation 1, we have x1 + x2 + 4 = 4 + 5x2. Simplifying, we get x1 - 4x2 = 0. Finally, from Equation 3, we have 5x1 + 3x2 - 4a = b.

To have no solutions, the equations must be inconsistent. In other words, the system of equations must be such that the equations are not compatible and cannot be satisfied simultaneously. This occurs when the coefficients of x1, x2, and x3 in the simplified equations lead to inconsistent relationships between the variables. By analyzing the coefficients, we can determine the values of a and b that result in no solutions.

To find the values of a and b for which the system has a unique solution, we need to analyze the equations and determine when they are consistent and non-contradictory. In other words, the system of equations must have a unique solution that satisfies all the equations. By solving the equations and examining the coefficients, we can identify the values of a and b that lead to a unique solution.

In conclusion, to find the values of a and b for which the given system of equations has no solutions or a unique solution, we need to solve the system of equations and analyze the coefficients. By examining the consistency and non-contradictory conditions, we can determine the appropriate values of a and b for each case.

a = 2(√2 + √10)/√3 and b = 4(√2 - √10) are the required values of sides a and b respectively.

Given,
A = π/6
B = 8π/9
C = π - A - B = π - π/6 - 8π/9 = 5π/18
c = 4
In order to find sides a and b, we will use sine rule which states that for a triangle with sides a, b and c and angles A, B and C respectively,
a/sinA = b/sinB = c/sinC
Applying the above formula, we get:
a/sinA = c/sinC
a/sin(π/6) = 4/sin(5π/18)
a/(1/2) = 4/(√2 + √10)/4
a = 2(√2 + √10)/√3
b/sinB = c/sinC
b/sin(8π/9) = 4/sin(5π/18)
b/(√2 - √10)/2 = 4/(√2 + √10)/4
b = 4(√2 - √10)

Therefore, a = 2(√2 + √10)/√3 and b = 4(√2 - √10) are the required values of sides a and b respectively.Summary:Given, A = π/6, B = 8π/9, C = π - A - B = π - π/6 - 8π/9 = 5π/18 and c = 4.

Performing long division on the function f(x) = (x² + 12)/(x² - 2x + 4), we have:

    ___________

x² - 2x + 4 | x² + 0x + 12

- (x² - 2x + 4)

____________

2x + 8

The remainder of the division is 2x + 8, and the quotient is 1. Therefore, we can write f(x) as:

f(x) = x + 1 + (2x + 8)/(x² - 2x + 4)

As x approaches infinity or negative infinity, the term (2x + 8)/(x² - 2x + 4) approaches 0. This means that the vertical distance between the curve and the line y = x + 1 approaches 0 as x becomes large.

Hence, the equation of the slant asymptote is y = x + 1.

To sketch the graph of the function, we can plot some key points and the slant asymptote. The slant asymptote y = x + 1 gives us an idea of the behavior of the function for large values of x.

We can choose some x-values, calculate the corresponding y-values using the function f(x), and plot these points. Additionally, we can plot the intercepts and any other relevant points.

By sketching the graph, we can observe how the function approaches the slant asymptote as x becomes large and gain insights into the behavior of the function for different values of x.

To calculate the probability that more than one customer will require service during a particular hour at the muffler shop, we can use the Poisson distribution. The Poisson distribution is commonly used to model the number of events occurring in a fixed interval of time or space, given the average rate of occurrence.

In this case, the average rate of customers arriving at the facility is two customers per hour. Let's denote this average rate as λ (lambda). The Poisson distribution is defined as:

P(X = k) = [tex](e^(-λ) * λ^k) / k![/tex]

Where:

- P(X = k) is the probability that there are exactly k customers arriving in the given hour.

- e is Euler's number, approximately equal to 2.71828.

- λ is the average rate of customers arriving per hour.

- k is the number of customers we're interested in (more than one in this case).

- k! is the factorial of k.

To calculate the probability that more than one customer will require service, we need to sum the probabilities for k = 2, 3, 4, and so on, up to infinity. However, for practical purposes, we can stop at a reasonably large value of k that covers most of the probability mass. Let's calculate it up to k = 10.

The probability of more than one customer requiring service can be found using the complement rule:

P(X > 1) = 1 - P(X ≤ 1)

Now, let's calculate it step by step:

P(X = 0) = [tex](e^(-λ) * λ^0) / 0! = e^(-2)[/tex] ≈ 0.1353

P(X = 1) = [tex](e^(-λ) * λ^1) / 1! = 2 * e^(-2)[/tex] ≈ 0.2707

P(X > 1) = 1 - P(X ≤ 1) = 1 - (P(X = 0) + P(X = 1))

P(X > 1) ≈ 1 - (0.1353 + 0.2707) ≈ 1 - 0.406 ≈ 0.594

Therefore, the probability that more than one customer will require service during a particular hour is approximately 0.594, or 59.4%.

To find the mean, we add up all the scores and divide by the total number of scores. Hence, the mean is:$$\begin{aligned} \text{Mean}&= \frac{7+4+9+6+10+9+5+9+9+5+4}{11}\\ &=\frac{77}{11}\\ &= 7 \end{aligned}$$To find the median, we first arrange the scores in order from smallest to largest.4, 4, 5, 5, 6, 7, 9, 9, 9, 9, 10We can see that there are 11 scores in total. The median is the middle score, which is 7.

Hence, the median is 7.Now, we need to find the sum of the mean and the median. We add the mean and the median to get:$$\begin{aligned} \text{Sum of mean and median} &= \text{Mean} + \text{Median}\\ &= 7+7\\ &= 14 \end{aligned}$$Therefore, the sum of the mean and the median of the given sample is 14.

The sum of the mean and the median can be found by first calculating the mean and the median separately and then adding them together.

The mean is the average of all the numbers in the data set. To find the mean, we sum all the numbers and then divide by the total number of numbers in the data set. In this case, there are 10 numbers: 7, 4, 9, 6, 10, 9, 5, 9, 9, 5.

Sum of all numbers = 7+4+9+6+10+9+5+9+9+5 = 73

Mean = Sum of all numbers/Total number of numbers = 73/10 = 7.3

The median is the middle number in a sorted list of numbers. To find the median, we first need to sort the data set:

4, 4, 5, 5, 6, 7, 9, 9, 9, 10

The middle two numbers are 6 and 7. To find the median, we take the average of these two numbers:

Median = (6+7)/2 = 6.5

Now we can find the sum of the mean and the median:

Sum of mean and median = Mean + Median

= 7.3 + 6.5

The critical points and their nature are:

Local minimum at (0, 0),  Local maximum at (0, 6)

Local maximum at (-2, 0), Saddle point at (-2, 6)

To find the local maxima, local minima, and saddle points of the function f(x, y) = x³ + y³ + 3x² - 9y² - 8, we need to calculate its partial derivatives with respect to x and y and then solve the system of equations formed by setting both partial derivatives equal to zero.

∂f/∂x = 3x² + 6x

∂f/∂y = 3y² - 18y

Setting ∂f/∂x = 0 and ∂f/∂y = 0, we have:

3x² + 6x = 0 ...(1)

3y² - 18y = 0 ...(2)

Let's solve equation (1) for x:

3x(x + 2) = 0

So, either x = 0 or x + 2 = 0, which gives x = 0 or x = -2.

Now, let's solve equation (2) for y:

3y(y - 6) = 0

So, either y = 0 or y - 6 = 0, which gives y = 0 or y = 6.

Now we have four critical points: (0, 0), (0, 6), (-2, 0), and (-2, 6). We need to determine the nature of these critical points by analyzing the second-order partial derivatives. The second-order partial derivatives are:

∂²f/∂x² = 6x + 6

∂²f/∂y² = 6y - 18

∂²f/∂x∂y = 0

Let's evaluate these second-order partial derivatives at each of the critical points:

For (0, 0):

∂²f/∂x² = 6(0) + 6 = 6

∂²f/∂y² = 6(0) - 18 = -18

∂²f/∂x∂y = 0

The discriminant D = (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² = (6)(-18) - (0)² = -108.

Since D < 0 and ∂²f/∂x² = 6 > 0, we have a local minimum at (0, 0).

For (0, 6):

∂²f/∂x² = 6(0) + 6 = 6

∂²f/∂y² = 6(6) - 18 = 18

∂²f/∂x∂y = 0

The discriminant D = (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² = (6)(18) - (0)² = 108.

Since D > 0 and (∂²f/∂x²)(∂²f/∂y²) > 0, we have a local maximum at (0, 6).

For (-2, 0):

∂²f/∂x² = 6(-2) + 6 = -6

∂²f/∂y² = 6(0) - 18 = -18

∂²f/∂x∂y = 0

The discriminant D = (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² = (-6)(-18) - (0)² = 108.

Since D > 0 and (∂²f/∂x²)(∂²f/∂y²) > 0, we have a local maximum at (-2, 0).

For (-2, 6):

∂²f/∂x² = 6(-2) + 6 = -6

∂²f/∂y² = 6(6) - 18 = 18

∂²f/∂x∂y = 0

The discriminant D = (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² = (-6)(18) - (0)² = -108.
