To find the partial derivatives of the function[tex]f(x, y) = x^6 + 6xy^3 - 3y^4,[/tex]we differentiate the function with respect to x and y separately.

First, let's find the partial derivative with respect to x, denoted as ∂f/∂x or f_x:

f_x(x, y) = ∂/∂x[tex](x^6 + 6xy^3 - 3y^4)[/tex]

         = [tex]6x^5 + 6y^3[/tex]

Next, let's find the partial derivative with respect to y, denoted as ∂f/∂y or f_y:

         =[tex]18xy^2 - 12y^3[/tex]

Finally, let's find the second partial derivatives:

          = ∂/∂x ([tex]6x^5 + 6y^3[/tex])

          = [tex]30x^4[/tex]

f_yy(x, y) = ∂²/∂y² ([tex]x^6 + 6xy^3 - 3y^4[/tex])

          = ∂/∂y (1[tex]18xy^2 - 12y^3[/tex])

          = 36xy - 36y^2

Now, we can find the mixed partial derivative:

f_xy(x, y) = ∂²/∂y∂x [tex]x^6 + 6xy^3 - 3y^4[/tex])

          = ∂/∂y ([tex]6x^5 + 6y^3)[/tex])

          = [tex]18x^5 + 18y^2[/tex]

In summary:

[tex]f_x(x, y) = 6x^5 + 6y^3[/tex]

[tex]f_y(x, y) = 18xy^2 - 12y^3[/tex]

[tex]f_xx(x, y) = 30x^4[/tex]

The correct answer is : g(t) = 31 - 35t + 120t^2 + 90 does not have any inflection points.

An inflection point is a point on the graph of a function where the concavity changes. In other words, it is a point where the second derivative changes sign. To determine if a function has inflection points, we need to analyze the concavity of the function.

In the given function g(t) = 31 - 35t + 120t^2 + 90, we can find the second derivative by taking the derivative of the first derivative. The first derivative is g'(t) = -35 + 240t, and the second derivative is g''(t) = 240.

Since the second derivative, g''(t) = 240, is a constant, it does not change sign. Therefore, there are no points where the concavity changes, and the function g(t) = 31 - 35t + 120t^2 + 90 does not have any inflection points.

The correct explanation for the p-value of 0.23 is option A.

The correct conclusion is option D.

The p-value represents the probability of obtaining results as extreme or more extreme than the observed test statistic, assuming that the null hypothesis is true. In this case, the p-value of 0.23 suggests that if the null hypothesis is true (p = 0.3), there is a 23% chance of observing results as extreme as the test statistic or more extreme in repeated sampling.

The correct conclusion is option D: "Since this event is not unusual, she will not reject the null hypothesis." When conducting hypothesis testing, a common criterion is to compare the p-value to a predetermined significance level (usually denoted as α). If the p-value is greater than the significance level, it indicates that the observed results are not sufficiently unlikely under the null hypothesis, and therefore, there is insufficient evidence to reject the null hypothesis. In this case, with a p-value of 0.23, which is greater than the commonly used significance level of 0.05, the researcher would not reject the null hypothesis.

(ii) the second part of your question seems to be incomplete or unclear.

(i) to solve the differential equation (x – 4) y⁴ dx – 23 (y² – 3) dy = 0, we'll use the separable variable method.

rearranging the terms, we have:

(y² – 3) dy = (x – 4) y⁴ dx

now, we can separate the variables by dividing both sides by y⁴ (y² – 3):

(1 / y⁴) (y² – 3) dy = (x – 4) dx

simplifying the left side:

(1 / y⁴) (y² – 3) dy = (1 / y²) dy

integrating both sides:

∫ (1 / y²) dy = ∫ (x – 4) dx

to integrate the left side, we can use the substitution u = y² – 3:

∫ (1 / y²) dy = ∫ du

= u + c1

= y² – 3 + c1

now, integrating the right side:

∫ (x – 4) dx = (1/2)x² - 4x + c2

putting everything together, we have:

y² – 3 + c1 = (1/2)x² - 4x + c2

we can combine the constants c1 and c2 into a single constant c:

y² – 3 = (1/2)x² - 4x + c

now, let's use the initial condition dy/dx = 1, y(0) = 1 to find the value of c. substituting x = 0 and y = 1 into the equation:

#SPJ11 equation is:

The volume of the solid region Q cut from the sphere x^2+y^2+z^2=4 by the cylinder r = 2 sintheta is (8/45) π.

Since the cylinder is defined in polar coordinates, we will use polar coordinates to solve this problem.

The equation of the sphere is x^2 + y^2 + z^2 = 4, which can be rewritten in terms of polar coordinates as:

r^2 + z^2 = 4     (1)

The equation of the cylinder is r = 2 sin(theta), which again can be rewritten as r^2 = 2r sin(theta):

r^2 - 2r sin(theta) = 0

r(r - 2 sin(theta)) = 0

So, either r = 0 or r = 2 sin(theta).

We want to find the volume of the solid region Q that is cut from the sphere by the cylinder. Since the cylinder is symmetric about the z-axis, we only need to consider the part of the sphere in the first octant (x, y, z > 0) that lies inside the cylinder.

In polar coordinates, the limits of integration are:

0 ≤ r ≤ 2 sin(theta)

0 ≤ theta ≤ π/2

0 ≤ z ≤ sqrt(4 - r^2)

Using the cylindrical coordinate triple integral, we can write the volume of Q as:

V = ∫∫∫Q dV

= ∫∫∫Q r dz dr dtheta

= ∫0^(π/2) ∫0^(2 sin(theta)) ∫0^(sqrt(4-r^2)) r dz dr dtheta

= ∫0^(π/2) ∫0^(2 sin(theta)) r(sqrt(4-r^2)) dr dtheta

= ∫0^(π/2) [-1/3 (4 - r^2)^(3/2)]_0^(2 sin(theta)) dtheta

= ∫0^(π/2) [-8/3 (sin^2(theta))^3/2 + 8/3] dtheta

= [16/9 - 32/15] π/2

= (8/45) π

Therefore, the volume of the solid region Q cut from the sphere x^2+y^2+z^2=4 by the cylinder r = 2 sin(theta) is (8/45) π.

a) The probability that the officer will reach the boundary of the patrol area after walking the first 8 blocks can be calculated by considering the possible paths the officer can take. Since the officer randomly elects to go north, south, east, or west at each corner, there are 4 possible directions at each intersection.

After walking 8 blocks, the officer will have encountered 8 intersections and made 8 random choices. The total number of possible paths the officer can take is 4⁸ since there are 4 choices at each intersection. Out of these paths, we need to determine the number of paths that lead to the boundary of the patrol area.

To reach the boundary after 8 blocks, the officer must choose the correct sequence of directions that eventually takes them to one of the four sides of the patrol area. For each choice at an intersection, there is a 1/4 probability of selecting the correct direction towards the boundary. Therefore, the probability of the officer reaching the boundary after walking the first 8 blocks is (1/4)⁸.

b) To calculate the probability of the officer returning to the starting point after walking exactly 4 blocks, we need to consider the possible paths again. After 4 blocks, the officer will have encountered 4 intersections and made 4 random choices. The total number of possible paths the officer can take is 4⁴.

In order to return to the starting point, the officer must choose the correct sequence of directions that leads them back to the starting intersection. There is only one correct path that takes the officer back to the starting point after exactly 4 blocks. Therefore, the probability of the officer returning to the starting point after walking exactly 4 blocks is 1 out of the total number of possible paths, which is 1/4⁴.

The problem states that the starting salaries for engineering students have a mean of $2,600 and a standard deviation of $1,600. We are asked to find the probability that a random sample of 64 students from the school will have an average salary of more than $3,000 is approximately 2.28%.

To solve this problem, we can use the Central Limit Theorem, which states that the distribution of sample means tends to be approximately normal, regardless of the shape of the population distribution, as the sample size increases.

Since the sample size is large (n = 64), we can assume that the distribution of sample means will be approximately normal. The mean of the sample means will still be $2,600, but the standard deviation of the sample means, also known as the standard error, will be the population standard deviation divided by the square root of the sample size. In this case, the standard error is $1,600 / sqrt(64) = $200.

Next, we need to calculate the z-score, which measures the number of standard deviations an observation is from the mean. The z-score can be calculated using the formula: z = (sample mean - population mean) / standard error. In this case, the z-score is (3000 - 2600) / 200 = 2.

Finally, we can use a standard normal distribution table or a calculator to find the probability of a z-score greater than 2. The probability is approximately 0.0228 or 2.28%.

Therefore, the probability that a random sample of 64 students from the school will have an average salary of more than $3,000 is approximately 2.28%.

To find dy, we need to take the derivative of f(x) with respect to x:

f(x) = x^4 - 5x^3 + 2

f'(x) = 4x^3 - 15x^2

Now, we can substitute x = 2 to find the value of dy:

f'(2) = 4(2)^3 - 15(2)^2 = 8(8) - 15(4) = 64 - 60 = 4

Therefore, dy = 4.

To find Ay, we need to use the formula for the average rate of change:

Ay = (f(Ax+h) - f(Ax))/h

where Ax = -0.2 and h is a small change in x.

Let's choose h = 0.1:

f(Ax+h) = f(-0.2 + 0.1) = f(-0.1) = (-0.1)^4 - 5(-0.1)^3 + 2 = 0.0209

f(Ax) = f(-0.2) = (-0.2)^4 - 5(-0.2)^3 + 2 = 2.096

The sine function represents the vertical coordinate of points on the unit circle, while the cosine function represents the horizontal coordinate. For the sine function, as we move counterclockwise from 0° to 90°, the y-coordinate increases, hence sine increases. From 90° to 270°, the y-coordinate decreases, resulting in a decreasing sine.

Finally, from 270° to 360°, the y-coordinate increases again. Similarly, for the cosine function, as we move counterclockwise from 0° to 90°, the x-coordinate increases, hence cosine increases. From 90° to 180°, the x-coordinate decreases, resulting in a decreasing cosine.

Finally, from 180° to 270°, the x-coordinate decreases again. Sine is equal to 0 at 0°, 180°, and 360° because those angles correspond to the y-coordinate being 0 on the unit circle.

The quadrilateral with vertices at (1, -2, 3), (4, 3, -1), (2, 2, 1), and (5, 7, -3) is a parallelogram, and its area can be found using the cross product of two adjacent sides.

1

To show that the quadrilateral is a parallelogram, we need to demonstrate that opposite sides are parallel. Two vectors are parallel if and only if their cross product is the zero vector.

Let's consider the vectors formed by two adjacent sides of the quadrilateral: v1 = (4, 3, -1) - (1, -2, 3) = (3, 5, -4) and v2 = (2, 2, 1) - (1, -2, 3) = (1, 4, -2).

Now, we calculate their cross product: v1 × v2 = (3, 5, -4) × (1, 4, -2) = (-12, -2, 22).

Since the cross product is not the zero vector, we can conclude that the quadrilateral is indeed a parallelogram.

To find the area of the parallelogram, we can calculate the magnitude of the cross product: |v1 × v2| = √((-12)² + (-2)² + 22²) = √(144 + 4 + 484) = √632 = 2√158.

Therefore, the area of the quadrilateral is 2√158 square units.

The indefinite integral of 2x^2 + 8x - 1 dx is (2/3)x^3 + 4x^2 - x + C, where C is the constant of integration.

To find the indefinite integral of 2x^2 + 8x - 1 dx, we need to integrate each term separately.

The integral of x^n dx, where n is a constant, is (1/(n+1))x^(n+1). Applying this rule, we find:

∫(2x^2 + 8x - 1) dx = (2/3)x^3 + 4x^2 - x + C

The constant of integration, denoted by C, accounts for the fact that the derivative of a constant is zero. It represents an arbitrary constant term that could have been present in the original function but was lost during differentiation.

For the limit of (6x^3 - 8x + 9) / (4x^3 + 9) as x approaches -∞, we can use L'Hôpital's Rule if necessary.

L'Hôpital's Rule states that if the limit of a quotient of two functions is indeterminate (such as 0/0 or ∞/∞), then the limit of the derivative of the numerator divided by the derivative of the denominator may yield the same result.

In this case, the limit is not indeterminate as x approaches -∞, so L'Hôpital's Rule is not needed.

To find the limit of (6x^3 - 8x + 9) / (4x^3 + 9) as x approaches -∞, we can evaluate the expression by plugging in -∞ for x:

lim(x→-∞) (6x^3 - 8x + 9) / (4x^3 + 9) = (-∞)^3 / (∞)^3 = -1

Therefore, the limit of (6x^3 - 8x + 9) / (4x^3 + 9) as x approaches -∞ is -1.

Lastly, for the limit of 5 as x approaches 6+, no further calculations are necessary. The limit is simply 5, meaning that as x approaches 6 from the right (positive direction), the value of the function approaches 5.

An injective or one-to-one function is a function where each input value (x) corresponds to a unique output value (f(x)). In this case, the function f(x) = 2x assigns a unique value to each integer input x by multiplying it by 2.

For example, if we consider two different integers, say x1 and x2, if f(x1) = f(x2), then x1 must be equal to x2 because the function doubles the input. Hence, each input has a unique output, and there are no two distinct integers that map to the same value. This property makes the function f: ZZ (integers) with f(x) = 2x an injective or one-to-one function.

The equation of the hyperbola with a vertical transverse axis, one endpoint at (4,5), and asymptotes y - x = 0 and y + x = 8 is (x-4)^2/9 - (y-5)^2/16 = 1.

Given that the hyperbola has a vertical transverse axis, we can use the standard form equation for a hyperbola with a vertical transverse axis:

(x-h)^2/a^2 - (y-k)^2/b^2 = 1

where (h, k) represents the coordinates of the center of the hyperbola.

Since the asymptotes are y - x = 0 and y + x = 8, we can rewrite them in slope-intercept form:

y = x and y = -x + 8.

The center of the hyperbola lies at the intersection of the asymptotes, which is (4, 4) (solving the system of equations y = x and y + x = 8).

Now, we can determine the values of a and b by considering the distance between the center (4, 4) and the endpoint (4, 5). The distance between these points is the value of a.

Using the distance formula:

a = sqrt((4-4)^2 + (5-4)^2) = 1

To determine the value of b, we consider the distance from the center (4, 4) to the asymptotes. The distance from the center to an asymptote is the value of b.

Using the distance formula and the equation y = x (one of the asymptotes):

b = sqrt((4-0)^2 + (4-0)^2)/sqrt(2) = 4sqrt(2)

Therefore, the equation of the hyperbola is (x-4)^2/9 - (y-5)^2/16 = 1.

The Laplace transform of ƒ(t) = 2sin(nt) is F(s) = 2n / (s² + n²), valid for t < 2. It represents the Laplace transform of ƒ(t) = 2sin(nt) for t < 2.

The Laplace transform of a function ƒ(t) is defined as F(s) = ∫[0 to ∞] ƒ(t)e^(-st) dt. For the given function ƒ(t) = 2sin(nt), where n is a constant, we can apply the Laplace transform formula for sine functions: L{sin(nt)} = 2n / (s² + n²).

The Laplace transform is valid for t < 2, so the transform function F(s) is only applicable within that interval. The result can be obtained by substituting the appropriate values into the Laplace transform formula. Thus, F(s) = 2n / (s² + n²) represents the Laplace transform of ƒ(t) = 2sin(nt) for t < 2.

The sum of the series is 22450. The error in using S4 is infinite. The bounds for the sum are S4 + divergent and [tex]S4 + [510/4(6^4 - 5^4)].[/tex]

To compute the sum of the series [tex]\(\sum_{n=1}^{6} 5 \cdot 10n^3\),[/tex] we substitute the values of \(n\) from 1 to 6 into the expression [tex]\(5 \cdot 10n^3\)[/tex] and add them up:

[tex]\[S_6 = 5 \cdot 10(1^3) + 5 \cdot 10(2^3) + 5 \cdot 10(3^3) + 5 \cdot 10(4^3) + 5 \cdot 10(5^3) + 5 \cdot 10(6^3)\][/tex]

Simplifying the expression:

[tex]\[S_6 = 5 \cdot 10 + 5 \cdot 80 + 5 \cdot 270 + 5 \cdot 640 + 5 \cdot 1250 + 5 \cdot 2160\]\[S_6 = 50 + 400 + 1350 + 3200 + 6250 + 10800\]\[S_6 = 22450\][/tex]

Therefore, the sum of the series [tex]\(\sum_{n=1}^{6} 5 \cdot 10n^3\)[/tex] is 22450.

To estimate the error in using [tex]\(S_4\)[/tex] as an approximation of the sum of the series, we can use the remainder term formula for the integral test. The remainder term [tex]\(R_n\)[/tex]is given by:

[tex]\[R_n = \int_{n+1}^{\infty} f(x) \, dx\][/tex]

In this case, the function f(x) is [tex]\(5 \cdot 10x^3\)[/tex] and n = 4. So, we need to find the integral:

[tex]\[\int_{5}^{\infty} 5 \cdot 10x^3 \, dx\][/tex]

Evaluating the integral:

[tex]\[\int_{5}^{\infty} 5 \cdot 10x^3 \, dx = \left[ \frac{5 \cdot 10}{4}x^4 \right]_{5}^{\infty}\][/tex]

Since the upper limit is infinity, the integral diverges. Therefore, the error in using [tex]\(S_4\)[/tex] as an approximation of the sum of the series is infinite.

Lastly, using n = 4 and the fact that the series is a decreasing series, we can determine bounds on the sum of the series:

[tex]\[S_4 + \int_{4+1}^{\infty} 5 \cdot 10x^3 \, dx < S < S_4 + \int_{4+1}^{4+2} 5 \cdot 10x^3 \, dx\][/tex]

Simplifying:

[tex]\[S_4 + \int_{5}^{\infty} 5 \cdot 10x^3 \, dx < S < S_4 + \int_{5}^{6} 5 \cdot 10x^3 \, dx\][/tex]

Substituting the integral values:

[tex]\[S_4 + \left[ \frac{5 \cdot 10}{4}x^4 \right]_{5}^{\infty} < S < S_4 + \left[ \frac{5 \cdot 10}{4}x^4 \right]_{5}^{6}\][/tex]

Since the integral from 5 to infinity diverges, we have:

[tex]\[S_4 + \text{divergent} < S < S_4 + \left[ \frac{5 \cdot 10}{4}(6^4 - 5^4) \right]\][/tex]

Therefore, the bounds for the sum of the series are [tex]\(S_4 + \text{divergent}\) and \(S_4 + \left[ \frac{5 \cdot 10}{4}(6^4 - 5^4) \right]\).[/tex]

Thereforre, the results can be expressed as follows:

The sum of the series is 22450.

The error in using [tex]\(S_4\)[/tex] as an approximation of the sum of the series is infinite.

The bounds for the sum of the series are[tex]\(S_4 + \text{divergent}\) and \(S_4 + \left[ \frac{5 \cdot 10}{4}(6^4 - 5^4) \right]\).[/tex]

We are given the function y = x^3 and asked to find the area under the curve over the interval [0, 1] using two different parametrizations: (a) x = t, y = t^6, and (b) x = t, y = t'.

The answer involves finding the parametric equations, calculating the derivatives, setting up the integral, and evaluating it to find the area.

(a) For the parametrization x = t, y = t^6, we can calculate the derivatives dx/dt = 1 and dy/dt = 6t^5. The integral for finding the area becomes ∫[0,1] y dx = ∫[0,1] (t^6)(1) dt. Evaluating this integral gives us the area under the curve for this parametrization.

(b) For the parametrization x = t, y = t', we need to find the derivative dy/dx. Differentiating y = x^3 with respect to x gives us dy/dx = 3x^2. Substituting this into the integral ∫[0,1] y dx = ∫[0,1] (t')(3x^2) dt, we can evaluate the integral to find the area under the curve for this parametrization.

By evaluating the integrals for both parametrizations, we can find the respective areas under the curve y = x^3 over the interval [0, 1]. The specific calculations will depend on the parametrization used and involve integrating the appropriate expression with respect to the parameter t.

Note: The specific calculations for the integrals are not provided in this summary, but they can be performed using standard integration techniques to find the areas under the curve for each parametrization.

Ava and Kelly will be 3/4 mile apart after 22.5 minutes.

To determine when Ava and Kelly will be 3/4 mile apart, we can consider their relative speed. The relative speed is the difference between their individual speeds.

Ava's speed = 6 miles per hour

Kelly's speed = 8 miles per hour

The relative speed of Ava and Kelly is:

Relative speed = Kelly's speed - Ava's speed

= 8 miles per hour - 6 miles per hour

= 2 miles per hour

This means that Ava and Kelly are moving away from each other at a rate of 2 miles per hour.

To calculate the time it takes for them to be 3/4 mile apart, we can use the formula:

Distance = Speed × Time

In this case, the distance they need to cover is 3/4 mile, and the relative speed is 2 miles per hour.

3/4 mile = 2 miles per hour × Time

Simplifying the equation:

3/4 = 2 × Time

Dividing both sides by 2:

3/4 × 1/2 = Time

3/8 = Time

Therefore, it will take Ava and Kelly 3/8 hours (or 22.5 minutes) to be 3/4 mile apart.

Thus, Ava and Kelly will be 3/4 mile apart after 22.5 minutes.

After solving the initial-value problem, the value of y(2) is 1.888.

Given differential equation is 24y + 5y - 3y = 0`.

Initial conditions are y(0) = -1, y'(0) = 31.

To solve the given initial-value problem, we can use the characteristic equation method which gives the value of `y`.

Step 1: Write the characteristic equation. We can rewrite the differential equation as:
24r² + 5r - 3 = 0
Solve the above equation using the quadratic formula to get:

r = (-5 ± √(5² - 4(24)(-3))) / (2(24))
This simplifies to:

r = (-5 ± 7i) / 48

Step 2: Write the general solution.

Using the roots from above, the general solution to the differential equation is:
y(t) = [tex]e^(-5t/48) (c₁cos((7/48)t) + c₂sin((7/48)t))[/tex]

where `c₁` and `c₂` are constants.

Step 3: Find the constants `c₁` and `c₂` using the initial conditions. To find `c₁` and `c₂`, we use the initial conditions `y(0) = -1, y'(0) = 31`.

The value of `y(0)` is:

y(0) = e^(0)(c₁cos(0) + c₂sin(0))
    = c₁
The value of `y'(0)` is:

y'(t) = -5/48e^(-5t/48)(c₁cos((7/48)t) + c₂sin((7/48)t)) + 7/48e^(-5t/48)(-c₁sin((7/48)t) + c₂cos((7/48)t))

y'(0) = -5/48(c₁cos(0) + c₂sin(0)) + 7/48(-c₁sin(0) + c₂cos(0))
     = -5/48c₁ + 7/48c₂

Substituting `y(0) = -1` and `y'(0) = 31`, we get the system of equations:
-1 = c₁
31 = -5/48c₁ + 7/48c₂

Solving the above system of equations for `c₁` and `c₂`, we get:
c₁ = -1
c₂ = 2321/33

Step 4: Find `y(2)`. Using the constants found in step 3, we can now find `y(2)`.
y(2) = e^(-5/24)(-1 cos(7/24) + 2321/336 sin(7/24))
    ≈ 1.888

Hence, the value of y(2) is 1.888.

The series given by aₙ = (-4)ⁿ/n! converges.

To determine whether the series given by aₙ = (-4)ⁿ/n! converges or diverges, we can apply the ratio test.

The ratio test states that if the limit of the absolute value of the ratio of successive terms is less than 1, the series converges. If the limit is greater than 1 or it does not exist, the series diverges.

Let's find the ratio of successive terms:

aₙ = (-4)ⁿ/n!

aₙ₊₁ = (-4)ⁿ⁺¹/(n+1)!

To calculate the ratio, we divide aₙ₊₁ by aₙ:

|r| = |aₙ₊₁ / aₙ| = |((-4)ⁿ⁺¹/(n+1)!) / ((-4)ⁿ/n!)|

Simplifying the expression:

|r| = |(-4)ⁿ⁺¹/(n+1)!| * |n! / (-4)ⁿ|

The factor of (-4)ⁿ cancels out:

|r| = |-4/(n+1)|

Taking the limit as n approaches infinity:

Lim (n→∞) |-4/(n+1)| = 0

Since the limit is 0, which is less than 1, we can conclude that the series converges by the ratio test.

Therefore, the series given by aₙ = (-4)ⁿ/n! converges.

To find the equation of the plane containing lines L1 and L2, we first need to find two points on each line.

For L1, we can choose t=0 and t=1 to get point P1(1, 2, 3) and point P2(3, 5, 7).

For L2, we can choose s=0 and s=1 to get point P3(2, 4, -1) and point P4(3, 6, -5).

Next, we can find two vectors that lie on the plane by subtracting the coordinates of the two points:

Vector v1 = P2 - P1 = (3-1, 5-2, 7-3) = (2, 3, 4)

Vector v2 = P4 - P3 = (3-2, 6-4, -5+1) = (1, 2, -4)

Finally, we can find the equation of the plane by taking the cross product of the two vectors:

Normal vector n = v1 x v2 = (2, 3, 4) x (1, 2, -4) = (-14, 12, -1)
