To ensure that the sum of a series is accurate to within 0.0002, we need to find the point at which adding more terms does not significantly change the sum.

Let's assume that the series we're dealing with converges. To ensure that the sum is accurate to within 0.0002, we need to find a point where adding more terms won't significantly change the value of the sum. In other words, we want to reach a point where the sum of the remaining terms is less than or equal to 0.0002.

Let's consider an example to illustrate this concept. Suppose we have a series with the following terms: 0.1, 0.05, 0.025, 0.0125, ...

We can start by calculating the sum of the first two terms: 0.1 + 0.05 = 0.15. Next, we add the third term:

0.15 + 0.025 = 0.175.

Continuing this process, we add the fourth term:

0.175 + 0.0125 = 0.1875.

At this point, we can observe that adding the fifth term, 0.00625, will not change the sum significantly. The difference between the sum of the first four terms and the sum of the first five terms is only 0.00015, which is less than our desired accuracy of 0.0002. Therefore, we can conclude that including the first five terms in the sum will ensure an accuracy within 0.0002.

In general, the number of terms required for a desired level of accuracy depends on the specific series being considered. Some series converge more rapidly than others, which means that fewer terms are needed to achieve a given level of accuracy.

Additionally, there are mathematical techniques and formulas, such as Taylor series expansions, that can be used to approximate the sum of certain types of series with a desired level of accuracy.

The given function is f(x, y) = - 3+ 2x - 32 - 2y + 7y. We are required to find the critical point of the function. The critical point is a point at which the function attains a maximum, a minimum, or an inflection point.

To find the critical point of a function of two variables, we differentiate the function partially with respect to x and y.

If there is a solution to the simultaneous equations formed by setting these partial derivatives equal to zero, then it is a critical point.

Partial derivative with respect to x isf_x(x,y) = 2 and the partial derivative with respect to y isf_y(x,y) = 5.

Now, we have to set these partial derivatives equal to zero and solve for x and y as shown below;2 = 05 = 0.

The above set of simultaneous equations does not have a solution.

Thus, there is no critical point.

If function y= [tex](2r^2 + 1) arctan(r) - √r[/tex] then the derivative can be found as y' = [tex]4r * arctan(r) + (2r^2 + 1) / (1 + r^2) - 1 / (2√r).[/tex]

(i) To find y', we differentiate y with respect to r using the chain rule:

y = (2r^2 + 1) arctan(r) - √r

Applying the chain rule, we have:

y' = (2r^2 + 1)' * arctan(r) + (2r^2 + 1) * arctan'(r) - (√r)'

= 4r * arctan(r) + (2r^2 + 1) * (1 / (1 + r^2)) - (1 / (2√r))

= 4r * arctan(r) + (2r^2 + 1) / (1 + r^2) - 1 / (2√r)

Therefore, y' = 4r * arctan(r) + (2r^2 + 1) / (1 + r^2) - 1 / (2√r).

(ii) To find y', we differentiate y with respect to r using the chain rule:

y = sinh(2r log(r))

Using the chain rule, we have:

y' = cosh(2r log(r)) * (2 log(r) + 2r / r)

= 2cosh(2r log(r)) * (log(r) + r) / r.

Therefore, y' = 2cosh(2r log(r)) * (log(r) + r) / r.

(b) To find y' using logarithmic differentiation, we take the natural logarithm of both sides of the equation:

ln(y) = ln(x^3 * 6^2 * cosh(a * 2x))

Using logarithmic properties, we can rewrite the equation as:

ln(y) = ln(x^3) + ln(6^2) + ln(cosh(a * 2x))

Differentiating implicitly with respect to x, we have:

(1/y) * y' = 3/x + 0 + (tanh(a * 2x)) * (a * 2)

Simplifying further, we obtain:

y' = y * (3/x + 2a * tanh(a * 2x))

Substituting y = x^3 * 6^2 * cosh(a * 2x), we have:

y' = x^3 * 6^2 * cosh(a * 2x) * (3/x + 2a * tanh(a * 2x))

Therefore, y' = x^3 * 6^2 * cosh(a * 2x) * (3/x + 2a * tanh(a * 2x)).

Answer:

The area completely enclosed by the graphs of the level curves is 4π.

Step-by-step explanation:

To sketch the level curves of the function f(x, y) = 16 - x^2 - y^2 for different values of z, we can plug in the given values of z (0, 1, 2, 3, 4) into the equation and solve for x and y. The level curves represent the points (x, y) where the function f(x, y) takes on a specific value (z).

For z = 0:

0 = 16 - x^2 - y^2

This equation represents a circle centered at the origin with a radius of 4. The level curve for z = 0 is a circle of radius 4.

For z = 1:

1 = 16 - x^2 - y^2

This equation represents a circle centered at the origin with a radius of √15. The level curve for z = 1 is a circle of radius √15.

Similarly, for z = 2, 3, 4, we can solve the corresponding equations to find the level curves. However, it is worth noting that for z = 4, the equation does not have any real solutions, indicating that there are no level curves for z = 4 in the real plane.

Now, to find the area completely enclosed by the graphs of the level curves, we need to find the region bounded by the curves.

The area enclosed by a circle of radius r is given by the formula A = πr^2. Therefore, the area enclosed by each circle is:

For z = 0: A = π(4^2) = 16π

For z = 1: A = π((√15)^2) = 15π

For z = 2: A = π((√14)^2) = 14π

For z = 3: A = π((√13)^2) = 13π

To find the area completely enclosed by the graphs of all the level curves, we need to subtract the areas enclosed by the inner level curves from the area enclosed by the outermost level curve.

Area = (16π - 15π) + (15π - 14π) + (14π - 13π) = 4π

Therefore, the area completely enclosed by the graphs of the level curves is 4π.

To determine the intervals on which a function is increasing or decreasing, we need to analyze the sign of its derivative. If the derivative is positive, the function is increasing, and if the derivative is negative, the function is decreasing.

1. Function: f(x) = 2x² - 6x⁴

First, let's find the derivative of f(x):

f'(x) = 4x - 24x³

To determine the intervals of increasing and decreasing, we need to find the critical points where f'(x) = 0 or is undefined.

Setting f'(x) = 0, we solve for x:

4x - 24x³ = 0

4x(1 - 6x²) = 0

From this equation, we find two critical points: x = 0 and x = 1/√6.

Next, we can construct a sign chart or use test points to determine the sign of the derivative in each interval:

Interval (-∞, 0): Test x = -1

f'(-1) = 4(-1) - 24(-1)^3 = -4 + 24 = 20 > 0 (increasing)

Interval (0, 1/√6): Test x = 1/√7

f'(1/√7) = 4(1/√7) - 24(1/√7)³ = 4/√7 - 24/7√7 < 0 (decreasing)

Interval (1/√6, ∞): Test x = 1

f'(1) = 4(1) - 24(1)³ = 4 - 24 = -20 < 0 (decreasing)

From the analysis, we can conclude that f(x) is increasing on the interval (-∞, 0) and decreasing on the intervals (0, 1/√6) and (1/√6, ∞).

To find the x-coordinates of relative maxima or minima, we can examine the concavity of the function. However, since the given function is a quartic function, it does not have any relative extrema.

2. Function: f(x) = 6x + 6x³

First, let's find the derivative of f(x):

f'(x) = 6 + 18x²

To determine the intervals of increasing and decreasing, we need to find the critical points where f'(x) = 0 or is undefined.

Setting f'(x) = 0, we solve for x:

6 + 18x² = 0

18x² = -6

x² = -1/3

Since the equation has no real solutions, there are no critical points or relative extrema for this function.

Therefore, for the function f(x) = 6x + 6x³, it is increasing on the entire domain and has no relative extrema.

The derivative of cosh(x) is sinh(x), so the derivative of y = 50 cosh(x) is dy/dx = 50 sinh(x). To approximate the slope at a specific point i, we substitute the x-coordinate of that point into the derivative expression.

When the diameter of the sphere is 60 mm, its radius is 30 mm. The formula for the volume of a sphere is V = (4/3)πr^3, where r is the radius.

To find how fast the volume is increasing, we need to take the derivative of V with respect to time, which gives dV/dt = 4πr^2 (dr/dt). Substituting the given values, we get dV/dt = 4π(30)^2 (2) = 7200π mm^3/s. Therefore, the volume of the sphere is increasing at a rate of 7200π mm^3/s when the diameter is 60 mm. The radius of a sphere is increasing at a rate of 2 mm/s. When the diameter is 60 mm, the radius is 30 mm. The volume of a sphere is given by the formula V = (4/3)πr³. Using the chain rule, dV/dt = (4/3)π(3)r²(dr/dt), where dV/dt is the rate of volume increase and dr/dt is the rate of radius increase. Plugging in r = 30 mm and dr/dt = 2 mm/s, we get dV/dt = 4π(30)²(2) = 7200π mm³/s. So, the volume is increasing at a rate of 7200π mm³/s when the diameter is 60 mm.

The volume of the solid generated when R is revolved about the horizontal line y = 10 is [tex]${{\frac{56}{15}}\pi - 6 \ln 2\pi}$[/tex], the volume of the solid whose base is region R and whose cross-section perpendicular to the x-axis is an isosceles right triangle with a leg in R is $9$.

Given the functions,[tex]$f(x) = \ln (x^2+1), g(x) = 10 - x^2$[/tex] and the region, $R$ bounded by the graphs of $f$ and $g$ is revolved about the horizontal line $y = 10$, let's determine the volume of the solid generated. We are required to compute the volume of the solid generated by revolving the region R about the horizontal line y = 10 using the cylindrical shell method.

Cylindrical shells are used to calculate the volume of solid objects by integrating the surfaces area of a cross-section using the height, or the length dimension, as a variable. To obtain the volume of the solid, the sum of all such shells should be taken.

The radius of the cylindrical shells is given by the distance from the rotation line to the edge of the region. In this case, the rotation line is $y = 10$, so the radius is the distance from this line to the function values, i.e.,[tex]$$r(x) = 10 - g(x) = 10 - (10 - x^2) = x^2.$$[/tex]

Hence, the volume of the solid generated by revolving the region R about the horizontal line[tex]$y = 10$ is given by;$$V = \int_{-3}^3 2 \pi x^2[f(x) - g(x)]dx.$$[/tex]Thus, we have;[tex]$$V = \int_{-3}^3 2\pi x^2[\ln (x^2 + 1) - (10 - x^2)]dx$$$$= 2\pi \int_{-3}^3 (x^4 - x^2 \ln (x^2 + 1) - 10x^2)dx$$$$= 2\pi \left[\frac{x^5}{5} - \frac{x^3}{3} \ln (x^2 + 1) - \frac{10x^3}{3}\right]_{-3}^3$$$$= \frac{56}{15} \pi - 6 \ln 2\pi.$$[/tex]

Now, let us consider part (b) of the question. We are required to compute the volume of the solid whose base is region R and whose cross-section perpendicular to the x-axis is an isosceles right triangle with a leg in R.

The cross-sections are triangles whose height, base, and hypotenuse are all equal in length, i.e.,[tex]$$h = b = \sqrt{2} x.$$[/tex]

Thus, the area of a cross-section is;[tex]$$A = \frac{1}{2}bh = \frac{1}{2}x^2.$$[/tex]Therefore, the volume of the solid is given by;[tex]$$V = \int_{-3}^3 A(x) dx = \int_{-3}^3 \frac{1}{2}x^2 dx = \frac{18}{2} = 9.$$[/tex]

Hence, the volume of the solid generated when R is revolved about the horizontal line[tex]y = 10 is ${{\frac{56}{15}}\pi - 6 \ln 2\pi}$[/tex], the volume of the solid whose base is region R and whose cross-section perpendicular to the x-axis is an isosceles right triangle with a leg in R is $9$.

Given that it has a sunroof = 12 + 20 + 0 + 18 = 50

  with 4 doors = 20

20/50 = 2/5 = .4

we can say that the congruence `x² ≅ 1 (mod p)` has a solution if and only if `p = 2` or `p ≅ 1 (mod 4)`. Hence, the solution is p = 2 or p ≅ 1 (mod 4).

The given congruence `x² ≅ 1 (mod p)` has a solution if and only if `p = 2` or `p ≅ 1 (mod 4)`.

A solution is a value or set of values that can be substituted into an equation to make it true.

For example, the solution to the equation `x² - 3x + 2 = 0` is `x = 1` or `x = 2`.

Solution for the given congruence: The given congruence is `x² ≅ 1 (mod p)`.

We need to find the value of `p` for which the congruence has a solution.

Now, if the congruence `x² ≅ 1 (mod p)` has a solution, then we can say that `x ≅ ±1 (mod p)` because `1² ≅ 1 (mod p)` and `(-1)² ≅ 1 (mod p)`.

This implies that `p` must divide the difference of `x - 1` and `x + 1` i.e., `(x - 1)(x + 1) ≅ 0 (mod p)`.

This gives us two cases:

Case 1: `p` divides `(x - 1)(x + 1)` i.e., either `p` divides `(x - 1)` or `p` divides `(x + 1)`. In either case, we get `x ≅ ±1 (mod p)`.

Case 2: `p` does not divide `(x - 1)` or `(x + 1)` i.e., `p` and `x - 1` are coprime and `p` and `x + 1` are coprime as well.

Therefore, we can say that `p` divides `(x - 1)(x + 1)` only if `p` divides `(x - 1)` or `(x + 1)` but not both.

Now, `(x - 1)(x + 1) ≅ 0 (mod p)` implies that either `(x - 1) ≅ 0 (mod p)` or `(x + 1) ≅ 0 (mod p)`.

Therefore, we get two cases as follows:

Case A: `(x - 1) ≅ 0 (mod p)` implies that `x ≅ 1 (mod p)` and `x ≅ -1 (mod p)`.

Case B: `(x + 1) ≅ 0 (mod p)` implies that `x ≅ -1 (mod p)` and `x ≅ 1 (mod p)`.

Thus, we can conclude that if the congruence `x² ≅ 1 (mod p)` has a solution, then either `x ≅ 1 (mod p)` and `x ≅ -1 (mod p)`, or `x ≅ -1 (mod p)` and `x ≅ 1 (mod p)`.

Therefore, we can say that `p` must be such that it divides `(x - 1)(x + 1)` but not both `(x - 1)` and `(x + 1)` simultaneously. Hence, we get the following two cases:

Case 1: If `p = 2`, then `(x - 1)(x + 1)` is always divisible by `p`.

Therefore, `x ≅ ±1 (mod p)` for all `x`.

Case 2: If `p ≅ 1 (mod 4)`, then `(x - 1)` and `(x + 1)` are not both divisible by `p`.

Hence, `p` must divide `(x - 1)(x + 1)` for all `x`.

a. To use the substitution method, we first choose a part of the integrand to substitute. Let u be equal to 2x²+1, so du = 4x dx. We can manipulate the integrand by factoring out 5x and substituting u and du.

∫5x²√(2x²+1)dx = 5∫x√(2x²+1)xdx = 5/4∫√u du (since 4x dx = du)

To evaluate the integral, we simplify the new integral involving u.

5/4∫√u du = 5/4 * (2/3)u^(3/2) + C

Substituting back for u,

5/4 * (2/3)(2x²+1)^(3/2) + C

b. Similarly, we choose a part of the integrand to substitute, so we let u = x³, so du = 3x² dx. Then we can manipulate the integral by factoring out x² and substituting u and du.

∫x².5(201²)dx = ∫x²(201²)√x dx = 201²∫u.5/2 du (since 3x² dx = du)

Again, we simplify the new integral by raising u to the power of 7/2 and multiplying by 2/7.

201²∫u.5/2 du = 2/7 * 201² * (2/7)u^(7/2) + C

To count the number of valid groups, we can use the complementary counting principle.

First, let's calculate the total number of possible groups without limits. You can choose 10 people from a total of 20 people, and you can do C(20, 10) combinations. This will give you the total number of possible groups. Then count the number of all-boys or all-boys groups. Since there are 10 boys and 10 boys of hers, we can select all 10 of hers from both groups by methods C(10, 10) and C(10, 10) respectively.

To find the number of valid groups, subtract the number of invalid groups from the total. According to the complementary counting principle, the number of valid groups for given ways is:

C(20,10) - C(10,10) - C(10,10)

Simplification of representation:

C(20, 10) - 1 - 1 = C(20, 10) - 2

Given (1, y ) = y i + x j.

To find the equation of flow lines, solve the system of differential equation.

That implies

dx/dt = 1. --(1)

dy/dt = y. ----(2)

Integrating the first equation with respect to t gives,

x = t + c1

Integrating the second equation with respect to t gives,

ln|y| = t +c2.

Applying the exponential function to both sides,  we have,

|y| = e^(t+c2)

Considering the absolute value, we get

case 1: y>0

y = e^(t+c2)

y = e^t × e^c2

Case - 2 y< 0

y = -e^(t +c2)

y = -e^t × e^c2

By combining both the cases,

y = Ce^t  where C = ±e^C2.

This represents the general equation of the flow lines.

Hence, the required equation is y = Ce^t  where C = ±e^C2.

Given that F(x) = f(x^2), where f is a function, and the values f(4) = 6, f'(4) = 2, and S'(12) = 3, we need to find F'(2), the derivative of F(x) at x = 2.

A derivative is a security with a price that is dependent upon or derived from one or more underlying assets. The derivative itself is a contract between two or more parties based upon the asset or assets. Its value is determined by fluctuations in the underlying asset. To find F'(2), we first need to apply the chain rule. According to the chain rule, if F(x) = f(g(x)), then F'(x) = f'(g(x)) * g'(x). In this case, F(x) = f(x^2), so we can rewrite it as F(x) = f(g(x)) where g(x) = x^2. Now, let's find the derivatives needed for F'(2). Since f(4) = 6, it means f(g(2)) = f(2^2) = f(4) = 6. Similarly, since f'(4) = 2, it means f'(g(2)) * g'(2) = f'(4) * 2 = 2 * 2 = 4. Lastly, since S'(12) = 3, it implies that g'(2) = 3. Using the information obtained, we can calculate F'(2) using the chain rule formula:

F'(2) = f'(g(2)) * g'(2) = 4 * 3 = 12.

Therefore, the derivative F'(2) is equal to 12.

The probability that the gambler will win her bet is approximately 0.00476, or 0.476%.

To calculate the probability of the gambler winning her bet, we need to determine the total number of possible outcomes and the number of favorable outcomes.

In this case, there are seven horses, and the gambler must pick the top three finishers in the correct order. The total number of possible outcomes can be calculated using the concept of permutations.

The first-place finisher can be any one of the seven horses. Once the first horse is chosen, the second-place finisher can be any one of the remaining six horses. Finally, the third-place finisher can be any one of the remaining five horses.

Therefore, the total number of possible outcomes is: 7 * 6 * 5 = 210

Now, let's consider the favorable outcomes. The gambler must correctly pick the top three finishers in the correct order. There is only one correct order for the top three finishers.

Therefore, the number of favorable outcomes is: 1

The probability of the gambler winning her bet is given by the number of favorable outcomes divided by the total number of possible outcomes:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 1 / 210

Simplifying the fraction, the probability is:

Probability = 1/210 ≈ 0.00476

Therefore, the probability that the gambler will win her bet is approximately 0.00476, or 0.476%.

The problem involves finding the value of the integral Sº [2f(x) + 3g(x)] dx, given that the integral of f(x) / x f(x) dx is equal to 35 and the integral of g(x) dx is equal to 12.

To solve this problem, we can use linearity and the properties of integrals.

Linearity states that the integral of a sum is equal to the sum of the integrals. Therefore, we can split the integral Sº [2f(x) + 3g(x)] dx into two separate integrals: Sº 2f(x) dx and Sº 3g(x) dx.

Given that the integral of f(x) / x f(x) dx is equal to 35, we can substitute this value into the integral Sº 2f(x) dx. So, Sº 2f(x) dx = 2 * 35 = 70.

Similarly, given that the integral of g(x) dx is equal to 12, we can substitute this value into the integral Sº 3g(x) dx. So, Sº 3g(x) dx = 3 * 12 = 36.

Finally, we can add the results of the two integrals: 70 + 36 = 106. Therefore, the value of the integral Sº [2f(x) + 3g(x)] dx is 106.

The rock will hit the water after approximately 4.75 seconds.

To find the time it takes for the rock to hit the water, we need to determine the value of t when the height h is equal to zero. We can set the equation h = -16t^2 + 76t + 120 to zero and solve for t.

-16t^2 + 76t + 120 = 0

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. In this case, let's use the quadratic formula:

t = (-b ± √(b^2 - 4ac)) / (2a)

Plugging in the values a = -16, b = 76, and c = 120 into the formula, we get:

t = (-76 ± √(76^2 - 4(-16)(120))) / (2(-16))

Simplifying the equation further, we have:

t = (-76 ± √(5776 + 7680)) / (-32)

t = (-76 ± √(13456)) / (-32)

Since we are interested in the time it takes for the rock to hit the water, we discard the negative value:

t ≈ (-76 + √(13456)) / (-32)

Evaluating this expression, we find t ≈ 4.75 seconds. Therefore, it will take approximately 4.75 seconds for the rock to hit the water.

The language of "giving fractions like wholes" is not completely accurate because fractions represent parts of a whole, not complete wholes.

When students give fractions common denominators to add them, they are finding a common unit or denominator that allows for easier comparison and addition. However, referring to this process as "giving fractions like wholes" can be misleading. Fractions represent parts of a whole, not complete wholes.

A more accurate representation of a whole number and a fraction combined is a mixed number. A mixed number combines a whole number and a proper fraction, representing a complete quantity. For instance, 1 1/4 is a mixed number where 1 represents a whole number and 1/4 represents a fraction of that whole. Using mixed numbers provides a clearer understanding of the relationship between whole numbers and fractions, as it distinguishes between complete wholes and fractional parts.

(A) The derivative of f(x) = 2x^4 - 4x^2 + 1 is f'(x) = 8x^3 - 8x.

(B) The slope of the graph of f at x = 2 is 40.

(C) The equation of the tangent line at x = 2 is y = 36x - 63.

(D) The value(s) of x where f'(x) = 0 are x = 0 and x = 1.

(A) To find the derivative of f(x) = 2x^4 - 4x^2 + 1, we differentiate each term using the power rule. The derivative of 2x^4 is 8x^3, the derivative of -4x^2 is -8x, and the derivative of the constant term 1 is 0. Therefore, f'(x) = 8x^3 - 8x.

(B) The slope of the graph of f at a specific value of x can be found by evaluating f'(x) at that point. Substituting x = 2 into f'(x) gives f'(2) = 8(2)^3 - 8(2) = 40. Hence, the slope of the graph of f at x = 2 is 40.

(C) To find the equation of the tangent line at x = 2, we use the point-slope form of a line. Using the point (2, f(2)), we substitute x = 2 and evaluate f(2) = 2(2)^4 - 4(2)^2 + 1 = 33. Therefore, the equation of the tangent line is y - 33 = 40(x - 2), which simplifies to y = 40x - 63.

(D) To find the value(s) of x where f'(x) = 0, we set f'(x) equal to zero and solve the equation 8x^3 - 8x = 0. Factoring out 8x gives 8x(x^2 - 1) = 0. Thus, the values of x that satisfy f'(x) = 0 are x = 0 and x = ±1.

Answer:

Step-by-step explanation:

If 2/3 of the cornbread is left after dinner and 4 friends want to share it equally, we need to determine how much cornbread each friend will receive.

To find the amount of cornbread each friend will receive, we need to divide the remaining cornbread by the number of friends.

Let's assume the total amount of cornbread is represented by "C".

The remaining cornbread is 2/3 of the total:

Remaining cornbread = (2/3) * C

Since there are 4 friends, we divide the remaining cornbread by 4 to find the amount each friend will receive:

Amount per friend = Remaining cornbread / Number of friends

                 = [(2/3) * C] / 4

To divide by a fraction, we can multiply by its reciprocal:

Amount per friend = [(2/3) * C] * (1/4)

                 = (2/3) * (1/4) * C

                 = (2/12) * C

                 = (1/6) * C

Therefore, each friend will receive 1/6 of the total amount of cornbread.

Note: Without the specific value of "C" representing the total amount of cornbread, we cannot determine the exact quantity each friend will receive.

The first-order partial derivatives of f(x, y) are ∂f/∂x = 12x^2y^2 - 6x + 5y^2 and ∂f/∂y = 8x^3y - 6xy + 10xy^2. The second-order partial derivatives are ∂²f/∂x² = 24xy^2 - 6, ∂²f/∂y² = 8x^3 + 20xy, and ∂²f/∂x∂y = 24x^2y - 6x + 20y^2.

The first-order partial derivatives of the function f(x, y) = 4x^3y^2 – 3x^2 + 5xy^2 can be calculated as follows:

∂f/∂x = 12x^2y^2 - 6x + 5y^2

∂f/∂y = 8x^3y - 6xy + 10xy^2

To find the second-order partial derivatives, we differentiate the first-order partial derivatives with respect to x and y:

∂²f/∂x² = 24xy^2 - 6

∂²f/∂y² = 8x^3 + 20xy

∂²f/∂x∂y = 24x^2y - 6x + 20y^2

By applying the Mixed Partial Derivative Theorem, we can check if the mixed partial derivatives are equal:

∂²f/∂x∂y = 24x^2y - 6x + 20y^2

∂²f/∂y∂x = 24x^2y - 6x + 20y^2

Since the mixed partial derivatives ∂²f/∂x∂y and ∂²f/∂y∂x are equal, we can conclude that fxy = fyx for this function.
