The series ∑(n=1 to ∞) 5n (12+6)⁽ⁿ⁻³³⁾ diverges.---

to find the fourth-degree taylor polynomial centered at c = 8 for the function f(x) = ln(x¹⁴), we can start by finding the derivatives of f(x) up to the fourth derivative.

to determine the convergence or divergence of the series ∑(n=1 to ∞) 5n (12+6)⁽ⁿ⁻³³⁾, we can use the direct comparison test.

first, let's simplify the series:

∑(n=1 to ∞) 5n (12+6)⁽ⁿ⁻³³⁾

= ∑(n=1 to ∞) 5n (18)⁽ⁿ⁻³³⁾

now, let's consider the series ∑(n=1 to ∞) 5n (18)⁽ⁿ⁻³³⁾.

to apply the direct comparison test, we need to find a convergent series with positive terms that bounds the given series from above.

let's consider the series ∑(n=1 to ∞) 5 (18)⁽ⁿ⁻³³⁾.

we can compare the given series with this series by dividing each term:

(5n (18)⁽ⁿ⁻³³⁾) / (5 (18)⁽ⁿ⁻³³⁾)

simplifying this expression, we get:

n / 1

since n/1 is a divergent series, if the original series is greater than or equal to this divergent series for all n, then the original series also diverges.

now, let's compare the two series:

5n (18)⁽ⁿ⁻³³⁾ ≥ 5 (18)⁽ⁿ⁻³³⁾ for all n

since the original series is greater than or equal to the divergent series, we can conclude that the original series also diverges. f(x) = ln(x¹⁴)

f'(x) = (1/x¹⁴)(14x¹³) = 14/x

f''(x) = -14/x²

f'''(x) = 28/x³

f''''(x) = -84/x⁴

now, let's evaluate these derivatives at x = 8:

f(8) = ln(8¹⁴) = ln(2⁴²) = 42 ln(2)

f'(8) = 14/8 = 7/4

f''(8) = -14/64 = -7/32

f'''(8) = 28/512 = 7/128

f''''(8) = -84/4096 = -21/1024

now, we can construct the fourth-degree taylor polynomial centered at c = 8:

p4(x) = f(8) + f'(8)(x - 8) + (f''(8)/2!)(x - 8)² + (f'''(8)/3!)(x - 8)³ + (f''''(8)/4!)(x - 8)⁴

p4(x) = 42 ln(2) + (7/4)(x - 8) - (7/64)(x - 8)² + (7/384)(x - 8)³ - (21/4096)(x - 8)⁴

so, the fourth-degree taylor polynomial centered at c = 8 for the function f(x) = ln(x¹⁴) is p4(x) = 42 ln(2) + (7/4)(x - 8) - (7/64

The given parametric equations define only one line.

To determine if the parametric equations define three different lines, two different lines, or only one line, we need to examine the direction vectors of the lines.

For equation 10:

x = 2 + 3s

y = -8 + 4s

z = 1 - 2s

The direction vector of this line is <3, 4, -2>.

For equation 11:

x = 4 + 9t

y = -8 + 4t

z = 1 - 2t

The direction vector of this line is <9, 4, -2>.

For equation 12:

x = 6t

y = -16 + 7t

z = 2 + 3t

The direction vector of this line is <6, 7, 3>.

If the direction vectors of the lines are linearly independent, then they define three different lines. If two of the direction vectors are linearly dependent, then they define two different lines. If all three direction vectors are linearly dependent, then they define only one line.

To check for linear dependence, we can create a matrix with the direction vectors as its columns and perform row operations to check if the matrix can be reduced to row-echelon form with a row of zeros.

The augmented matrix [A|0] for the direction vectors is:

[ 3 9 6 | 0 ]

[ 4 4 7 | 0 ]

[-2 -2 3 | 0 ]

By performing row operations, we can reduce this matrix to row-echelon form:

[ 1 1 0 | 0 ]

[ 0 4 1 | 0 ]

[ 0 0 0 | 0 ]

The reduced row-echelon form has a row of zeros, indicating that the direction vectors are linearly dependent.

To find the values of a and b, we can use the Remainder Theorem and the factor theorem. The values of m and n are determined to be m = -7 and n = 0.

According to the Remainder Theorem, when a polynomial f(x) is divided by x - c, the remainder is equal to f(c). Similarly, the factor theorem states that if f(c) = 0, then x - c is a factor of f(x). Given that f(x) is exactly divisible by 3x - 2, we can set 3x - 2 equal to zero and solve for x:

3x - 2 = 0

3x = 2

x = 2/3

Since f(x) is divisible by 3x - 2, we know that f(2/3) = 0.

Substituting x = 2/3 into the equation f(x) = ax^3 - 8x^2 - 9x + b, we get:

f(2/3) = a(2/3)^3 - 8(2/3)^2 - 9(2/3) + b = 0

Simplifying further:

(8a - 32 - 18 + 3b)/27 = 0

8a - 50 + 3b = 0

8a + 3b = 50 ...........(1)

Next, we are given that f(x) leaves a remainder of 6 when divided by x. This means that f(0) = 6. Substituting x = 0 into the equation f(x) = ax^3 - 8x^2 - 9x + b, we get:

f(0) = 0 - 0 - 0 + b = 6

Simplifying further:

b = 6 ...........(2)

Therefore, the values of a and b are determined to be a = 1 and b = 6.

Now, let's move on to the second part of the question:

We need to determine values of m and n so that 3x^3 + mx^2 - 5x + n is divisible by 2x + 1.

Since 3x^3 + mx^2 - 5x + n is divisible by 2x + 1, we can set 2x + 1 equal to zero and solve for x:

2x + 1 = 0

2x = -1

x = -1/2

Substituting x = -1/2 into the equation 3x^3 + mx^2 - 5x + n, we get:

3(-1/2)^3 + m(-1/2)^2 - 5(-1/2) + n = 0

Simplifying further:

(-3/8) + (m/4) + (5/2) + n = 0

(4m - 12 + 40 + 16n)/8 = 0

4m + 16n + 28 = 0

4m + 16n = -28

Using local linear approximation, the approximate value of 64.12 is 64 if the base value is taken as 64.

Local linear approximation is a method used to estimate the value of a function near a given point using its tangent line equation. In this case, the given value is 64.12, and we need to find its approximate value using local linear approximation, assuming the base value as 64.

To apply the local linear approximation method, we first need to find the tangent line equation of the function, which passes through the point (64, f(64)), where f(x) is the given function.

As we don't know the function here, we assume that the function is a linear function, which means it can be represented as f(x) = mx + b.

Now, we can find the slope of the tangent line at x = 64 by taking the derivative of the function at that point. As we don't know the function, again we assume that it is a constant function, which means the derivative is zero.

Therefore, the slope of the tangent line is zero, and hence its equation is simply y = f(64), which is a horizontal line passing through (64, f(64)).

Now, we can estimate the value of the function at 64.12 by finding the y-coordinate of the point where the vertical line x = 64.12 intersects the tangent line.

As the tangent line is a horizontal line passing through (64, f(64)), its y-coordinate is f(64). Therefore, the approximate value of the function at 64.12 is f(64) = 64.

Hence, using local linear approximation, the approximate value of 64.12 is 64 if the base value is taken as 64.

The equation of a cone in spherical coordinates can be expressed as p = [tex]\sqrt{x^{2} + y^{2} + z^{2}}[/tex], where p represents the radial distance from the origin to a point on the cone. In the given equation z = √3[tex]x^{2}[/tex] + 3[tex]y^{2}[/tex], we need to rewrite it in terms of p.

To convert the equation to spherical coordinates, we substitute x = p sin θ cos φ, y = p sin θ sin φ, and z = p cos θ, where θ represents the polar angle and φ represents the azimuthal angle.

Substituting these values into the equation z = √3[tex]x^{2}[/tex] + 3[tex]y^{2}[/tex], we get:

p cos θ = √3{(p sin θ cos φ)}^{2} + 3{(p sin θ sin φ)}^{2}

the integral of the given expression is -9cos(θ) - 9θ + 9sin(θ) + C, where C is the constant of integration.

To evaluate the integral, we start by simplifying the expression in the denominator. Using the identity sec²(θ) - sec(θ) = 1/cos²(θ) - 1/cos(θ), we get (1 - cos(θ)) / cos²(θ).Now, we can rewrite the integral as: 9sec(θ)tan(θ) / [(1 - cos(θ)) / cos²(θ)].To simplify further, we multiply the numerator and denominator by cos²(θ), which gives us: 9sec(θ)tan(θ) * cos²(θ) / (1 - cos(θ)).Next, we can use the trigonometric identity sec(θ) = 1/cos(θ) and tan(θ) = sin(θ) / cos(θ) to rewrite the expression as: 9(sin(θ) / cos²(θ)) * cos²(θ) / (1 - cos(θ)).

Simplifying the expression, we have: 9sin(θ) / (1 - cos(θ)).Now, we can integrate this expression with respect to θ. The antiderivative of sin(θ) is -cos(θ), and the antiderivative of (1 - cos(θ)) is θ - sin(θ).Finally, evaluating the integral, we have: -9cos(θ) - 9θ + 9sin(θ) + C, where C is the constant of integration.In summary, the integral of the given expression is -9cos(θ) - 9θ + 9sin(θ) + C, where C is the constant of integration.

The largest value of a that guarantees |f(x) - t2(x)| ≤ 0.01 for all x in j is approximately 0.141421.

In the quadratic approximation of a function f(x), the error bound is given by |f(x) - t2(x)| ≤ (a/2) * (x - c)^2, where a is the maximum value of the second derivative of f(x) on the interval j and c is the point of approximation.

To find the largest value of a that ensures |f(x) - t2(x)| ≤ 0.01 for all x in j, we need to determine the maximum value of the second derivative of f(x). This maximum value corresponds to the largest curvature of the function.

Once we have the maximum value of the second derivative, denoted as a, we can solve the inequality (a/2) * (x - c)^2 ≤ 0.01 for x in j. Rearranging the inequality, we have (x - c)^2 ≤ 0.02/a. Taking the square root of both sides, we obtain |x - c| ≤ √(0.02/a).

Since the inequality must hold for all x in j, the largest possible value of √(0.02/a) will determine the largest value of a. Therefore, we need to find the minimum upper bound for √(0.02/a), which is the reciprocal of the maximum lower bound. Calculating the reciprocal of √(0.02/a), we find the largest value of a to be approximately 0.141421 when rounded to six decimal places.

Let's denote Lynn's speed on the highway as x miles per hour. We are given that Lynn travels 3 miles on the highway and 2 miles on the side roads at a speed 10 mph slower than on the highway.

Let's denote Lynn's speed on the highway as "x" mph. Since Lynn travels 3 miles on the highway, the time taken for this portion of the trip is 3 miles / x mph = 3/x hours. Lynn's speed on the side roads is 10 mph slower, so her speed on the side roads is (x - 10) mph. Given that she travels 2 miles on the side roads, the time taken for this portion of the trip is 2 miles / (x - 10) mph = 2/(x - 10) hours.

According to the given information, the total time taken for the entire trip is 1 hour. Therefore, we can set up the equation: 3/x + 2/(x - 10) = 1. To solve this equation, we can find a common denominator and simplify. Multiplying both sides of the equation by x(x - 10), we get: 3(x - 10) + 2x = x(x - 10). Expanding and rearranging the terms, we have: 3x - 30 + 2x = x^2 - 10x. Simplifying further, we get: x^2 - 15x - 30 = 0.

Now, we can solve this quadratic equation. Factoring or using the quadratic formula, we find that x = 15 or x = -2. However, since speed cannot be negative, we discard the solution x = -2. Therefore, Lynn's speed is 15 mph.

Meaning that the column space of the matrix can span at most a three-dimensional space  col ≤ R³.

In a matrix, the pivot columns are the columns that contain the leading entry (the first non-zero entry) in each row of the matrix when it is in row echelon form or reduced row echelon form. In this case, the given 3 × 5 matrix has three pivot columns.

The column space (col) of a matrix is the subspace spanned by the columns of the matrix. To determine if col = R³ (the entire three-dimensional space), we need to consider the number of linearly independent columns in the matrix.

If a matrix has three pivot columns, it means that these three columns are linearly independent. Linearly independent columns span a subspace that is equivalent to their span. Since there are three linearly independent columns, the col of the matrix can span at most a three-dimensional subspace. Therefore, col ≤ R³.

On the other hand, the null space (nul) of a matrix is the set of all solutions to the homogeneous equation Ax = 0, where A is the matrix and x is a vector. The null space represents the vectors that, when multiplied by the matrix, yield the zero vector.

If the matrix has three pivot columns, it means that there are two free variables or columns (since the matrix has five columns). The free variables can be assigned any values, which implies that the null space can have infinitely many solutions. Therefore, the nul of the matrix can be a two-dimensional subspace.

To summarize, based on the information provided, col ≤ R³, meaning that the column space of the matrix can span at most a three-dimensional space. Additionally, the nul of the matrix can be a two-dimensional subspace.

The value of function f(g(x)) is √(x² + 2x).

What is function?

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealised relationship between two changing quantities.

As given function are,

f(x) = √(x² - 1) and g(x) = x + 1,

Thus,

f(g(x)) = f(x + 1)

f(g(x)) = √{(x + 1)² - 1}

f(g(x)) = √(x² + 2x + 1 -1)

(1) He takes the AMA and arrives on time, and (2) He takes the commuter train and arrives on time.Let's denote the event "Arrive on time" as A, and the event "Take the AMA" as B, and the event "Take the commuter train" as C.Using the law of total probability, we can calculate the probability of rriving on time as follows:

P(A) = P(B) * P(A | B) + P(C) * P(A | C)

Given:

P(B) = 0.7 (probability of taking the AMA)

P(A | B) = 0.6 (probability of arriving on time when taking the AMA)

P(C) = 0.3 (probability of taking the commuter train)

P(A | C) = 0.9 (probability of arriving on time when taking the commuter train)

The particular solution to the given differential equation dy/dx = x^2(2y-3)^2 with the initial condition y(0) = -1 can be found by separating variables and integrating.

To find the particular solution, we can separate variables and integrate both sides of the differential equation. Rearranging the equation, we have dy / (x^2(2y-3)^2) = dx.

To integrate the left side, we can use a substitution. Let u = 2y - 3, then du = 2dy, and the equation becomes (1/2) du / (x^2u^2).

Now, we can integrate both sides with respect to their respective variables. Integrating the left side gives us (1/2) ∫ du / u^2 = -(1 / (2u)).

For the right side, we integrate dx, which is simply x + C, where C is a constant of integration.

Putting the pieces together, we have -(1 / (2u)) = x + C.

Substituting back u = 2y - 3, we get -(1 / (2(2y - 3))) = x + C.

Simplifying, we have -1 / (4y - 6) = x + C.

Rearranging the equation to solve for y, we find 4y - 6 = -1 / (x + C).

Finally, solving for y, we have y = (3/2) - (1 / (2(x^3/3 + C))), where C is the constant of integration determined by the initial condition y(0) = -1.

Applying the logarithm characteristics first will help us determine the answer to the equation ln(2x + 4) = ln(x + 3). The arguments inside the logarithms can be equalised in this situation since the natural logarithm function (ln) is a one-to-one function.

ln(2x + 4) = ln(x + 3)

By setting the arguments equal, we have:

2x + 4 = x + 3

To solve for x, we can subtract x from both sides and subtract 4 from both sides:

2x - x = 3 - 4

x = -1

It's crucial to keep in mind that the logarithm's argument must be positive when taking the natural logarithm of an equation's two sides. The argument 2x + 4 and the argument x + 3 must both be greater than zero in this situation. We check that the equation's answer, x = -1, satisfies this requirement after solving the problem.

Never forget to verify the validity of the solution by reinserting it into the original equation.

As a result, x = -1 is the answer to the equation ln(2x + 4) = ln(x + 3).

The correct answer is D. X = -1.

The absolute value of the difference between the total differential approximation and the calculator approximation is 3.95 to four decimal places.

To approximate the quantity using the total differential, use the following formula:

Δf ≈ (∂f/∂x)Δx + (∂f/∂y)Δy

In this case, f(x, y) = 3.95, and to approximate the value of f when Δx = 0.1 and Δy = 0.05. Supposing that (∂f/∂x) = (∂f/∂y) = 0.

Δf ≈ (0)(0.1) + (0)(0.05) = 0

Therefore, using the total differential, the approximation of the quantity is 0.

Now, use a calculator to find the approximate value of 3.95:

3.95 (approximation using calculator) = 3.95

The absolute difference between the two results is:

|0 - 3.95| = 3.95

Therefore, the absolute value of the difference between the total differential approximation and the calculator approximation is 3.95 to four decimal places.

The Laplace transform of the given initial value problem is taken to solve for Y(s) as (s^2 - 3s - 40)Y(s) = J1(s).

To find the Laplace transform of the initial value problem, we apply the Laplace transform to each term of the differential equation. Using the properties of the Laplace transform, we have:

s^2Y(s) - sy(0) - y'(0) - 3(sY(s) - y(0)) - 40Y(s) = J1(s)

Rearranging the equation and substituting the initial conditions y(0) = 0 and y'(0) = 0, we obtain:

(s^2 - 3s - 40)Y(s) = J1(s)

Next, we need to find the inverse Laplace transform to obtain the solution y(t) in the time domain. However, the given problem does not specify the Laplace transform of the function J1(s).

Without this information, we cannot provide a specific solution or calculate Y(s) without additional details. The solution would involve finding the inverse Laplace transform of the expression (s^2 - 3s - 40)Y(s) = J1(s) once the Laplace transform of J1(t) is known.

The volume of the given circular cone is 24π cubic units.

The volume of the given circular cone can be found by integrating the areas of the cross-sectional circles along the height.

To find the volume using similar triangles, we can observe that the ratio of the radius of the cross-sectional circle at height y to the height y is constant and equal to the ratio of the radius of the base circle to the total height of the cone.

Let's denote the radius of the cross-sectional circle at height y as r(y). Using similar triangles, we have r(y)/y = 2/6. Simplifying, we get r(y) = y/3.

The area of a circle is given by A = πr². Substituting the expression for r(y), we have A(y) = π(y/3)² = πy²/9.

To find the volume, we integrate the areas of the cross-sectional circles with respect to the height y from 0 to 6:

V = ∫[0 to 6] A(y) dy

  = ∫[0 to 6] (πy²/9) dy.

Integrating the expression, we get V = (π/9) ∫[0 to 6] y² dy.

Evaluating this integral, we find V = (π/9) * (6³/3) = 24π cubic units.

To convert the angle 18,186 degrees to degrees, minutes, and seconds format, we can break down the angle into its respective components.

First, we know that there are 60 minutes in one degree. So, to find the number of degrees, we take the whole number part of 18,186, which is 18.

Next, we subtract the whole number part from the original angle: 18,186 - 18 = 186.

Since there are 60 seconds in one minute, we divide 186 by 60 to find the number of minutes: 186 / 60 = 3 remainder 6.

Finally, we have 3 minutes and 6 seconds.

Therefore, the angle 18,186 degrees can be expressed in degrees, minutes, and seconds as 18 degrees, 3 minutes, and 6 seconds.

a. The arc length function for F(t) is s(t) = √29 * (t - a).

b. The arc length parameterization for F(t) is r(t) = (2cos(t) / (√29 * (t - a)), 2sin(t) / (√29 * (t - a)), 5t / (√29 * (t - a))).

Find the arc length?

a. To find the arc length function for the space curve F(t) = (2cos(t), 2sin(t), 5t), we need to integrate the magnitude of the derivative of F(t) with respect to t.

First, let's find the derivative of F(t):

F'(t) = (-2sin(t), 2cos(t), 5)

Next, calculate the magnitude of the derivative:

[tex]|F'(t)| = \sqrt{(-2sin(t))^2 + (2cos(t))^2 + 5^2}\\ = \sqrt{4sin^2(t) + 4cos^2(t) + 25}\\ = \sqrt{(4 + 25)}\\ = \sqrt29[/tex]

Integrating the magnitude of the derivative:

s(t) = ∫[a, b] |F'(t)| dt

    = ∫[a, b] √29 dt

    = √29 * (b - a)

Therefore, the arc length function for F(t) is s(t) = √29 * (t - a).

b. To find the arc length parameterization for F(t), we divide each component of F(t) by the arc length function s(t):

r(t) = (2cos(t), 2sin(t), 5t) / (√29 * (t - a))

Therefore, the arc length parameterization for F(t) is r(t) = (2cos(t) / (√29 * (t - a)), 2sin(t) / (√29 * (t - a)), 5t / (√29 * (t - a))).

To find the positions as a function of time, we need to integrate the given velocity equation. By using the given initial condition v = 8√√√S, when t = 0, we can evaluate the constant of integration.

Let's start by integrating the given velocity equation v = ds/dt. Integrating both sides with respect to t will give us the position equation as a function of time:

∫v dt = ∫ds

Integrating v with respect to t will yield:

∫v dt = ∫8√√√S dt

To integrate 8√√√S dt, we can rewrite it as 8S^(1/8) dt. Applying the power rule of integration, we have:

∫v dt = ∫8S^(1/8) dt = 8 ∫S^(1/8) dt

Now, we have to evaluate the integral on the right-hand side. The integral of S^(1/8) with respect to t can be determined using the power rule of integration:

∫S^(1/8) dt = (8/9)S^(9/8) + C

Where C is the constant of integration. To determine the value of C, we use the given initial condition v = 8√√√S when t = 0. Substituting these values into the position equation, we have:

(8/9)S^(9/8) + C = 8√√√S

Simplifying the equation, we find:

C = 8√√√S - (8/9)S^(9/8)

Therefore, the position equation as a function of time is:

∫v dt = (8/9)S^(9/8) + 8√√√S - (8/9)S^(9/8)

This equation represents the positions as a function of time, and the constant of integration C has been evaluated using the given initial condition.

By differentiating the function x = Acosh(wt) + Bsinh(wt) twice and substituting it into the differential equation x'' - w^2 * x = 0, we can calculate that x'' = -Aw^2cosh(wt) - Bw^2sinh(wt) and w^2 * x = w^2 * (Acosh(wt) + Bsinh(wt)), resulting in x'' - w^2 * x = 0.

To verify that the function x = Acosh(wt) + Bsinh(wt) satisfies the differential equation x'' - w^2 * x = 0, we differentiate x twice and substitute it into the equation.

First, we find x' (the first derivative of x):

x' = Awsinh(wt) + Bwcosh(wt).

Next, we find x'' (the second derivative of x):

x'' = Aw^2cosh(wt) + Bw^2sinh(wt).

Substituting x'' and x into the differential equation x'' - w^2 * x = 0, we have:

(Aw^2cosh(wt) + Bw^2sinh(wt)) - w^2 * (Acosh(wt) + Bsinh(wt)).

Expanding and simplifying, we get:

Aw^2cosh(wt) + Bw^2sinh(wt) - Aw^2cosh(wt) - Bw^2sinh(wt) = 0.

This simplifies to:

0 = 0.

Therefore, by differentiating the function x = Acosh(wt) + Bsinh(wt) and substituting it into the differential equation x'' - w^2 * x = 0, we have shown that x'' = -Aw^2cosh(wt) - Bw^2sinh(wt) and w^2 * x = w^2 * (Acosh(wt) + Bsinh(wt)), resulting in x'' - w^2 * x = 0.

a) To determine which of the given series converge absolutely, converge conditionally, or diverge, we need to analyze the behavior of each series.

(i) 37Inn(Inn): This series involves nested natural logarithms. Without further information or constraints on the values of n, it is challenging to determine the convergence behavior of this series. More specific information or a pattern of terms is needed to make a conclusive assessment. (ii) (-1)n/(3): This series alternates between positive and negative terms. It resembles the alternating series form, where the terms approach zero and alternate in sign. We can apply the Alternating Series Test to determine its convergence. Since the terms approach zero and satisfy the conditions of alternating signs, we can conclude that this series converges.

(iii) Ση=1 2: In this series, the terms are constant and equal to 2. As the terms do not depend on n, the series becomes a sum of infinitely many 2's. Since the sum of constant terms is infinite, this series diverges. In summary, the series (-1)n/(3) converges, the series Ση=1 2 diverges, and the convergence behavior of the series 37Inn(Inn) cannot be determined without additional information or constraints on the values of n. b) To find the series's radius of convergence, we need additional information about the series. Specifically, we require the coefficients of the series or a specific pattern that characterizes the terms.

Without such information, it is not possible to determine the radius of convergence. The radius of convergence depends on the specific series and its coefficients, which are not provided in the question. Thus, we cannot calculate the radius of convergence without more specific details. In conclusion, the determination of the series's radius of convergence requires information about the series's coefficients or a specific pattern of terms, which is not given in the question. Therefore, it is not possible to provide the radius of convergence without further information.
