The given series, 53/n(-1)^n with n=11, is evaluated using the Divergence Test and it is determined that the limit as n approaches infinity is indeterminate. Therefore, the Divergence Test does not provide a conclusive result for the convergence or divergence of the series.

In the Divergence Test, we examine the limit of the terms of the series to determine convergence or divergence. For the given series, bn is defined as 53/n(-1)^n with n=11.

To evaluate the limit as n approaches infinity, we substitute infinity for n in the expression and observe the behavior. However, in this case, we have a specific value for n (n=11), not infinity. Therefore, we cannot directly apply the Divergence Test to determine convergence or divergence.

Since the limit of bn cannot be evaluated, we cannot make a definitive conclusion using the Divergence Test alone. The Alternating Series Test, which is used to determine the convergence of alternating series, is unnecessary in this case. It is important to note that without further information or additional tests, the convergence or divergence of the series remains unknown based on the given data.

To find the value of x, we need to use the fact that the lines appear to be tangent and therefore are tangent.

Tangent lines are lines that intersect a curve at only one point and are perpendicular to the curve at that point. So, if two lines appear to be tangent to the same curve, they must intersect that curve at the same point and be perpendicular to it at that point.

Without a specific problem to reference, it is difficult to provide a more detailed answer. However, generally, to find the value of x in this scenario, we would need to use the properties of tangent lines and the given information to set up an equation and solve for x. This may involve using the Pythagorean theorem, trigonometric functions, or other mathematical concepts depending on the specific problem. It is important to note that if the figures are not drawn to scale, it may be more difficult to accurately determine the value of x.

The work required to pump all of the oil to the surface is 30600π lb·ft (pound-foot).

To calculate the work required to pump all of the oil to the surface, we need to determine the weight of the oil and the distance it needs to be pumped.

Radius of the tank (r) = 6 feet

Height of the tank (h) = 18 feet

Current oil level (d) = 17 feet

Oil weight (w) = 50 lb/ft³

First, we need to find the volume of the oil in the tank. Since the tank is a cylinder, the volume of the oil can be calculated as the difference between the volume of the entire tank and the volume of the empty space above the oil level.

Volume of the tank (V_tank) = πr²h

Volume of the empty space (V_empty) = πr²(d + h)

Volume of the oil (V_oil) = V_tank - V_empty

V_oil = πr²h - πr²(d + h)

V_oil = π(6²)(18) - π(6²)(17 + 18)

V_oil = π(36)(18) - π(36)(35)

V_oil = π(36)(18 - 35)

V_oil = π(36)(-17)

V_oil = -612π ft³

Since the volume cannot be negative, we take the absolute value:

V_oil = 612π ft³

Next, we calculate the weight of the oil:

Weight of the oil (W_oil) = V_oil * w

W_oil = (612π ft³) * (50 lb/ft³)

W_oil = 30600π lb

Now, we need to find the distance the oil needs to be pumped, which is the height of the tank:

Distance to pump (d_pump) = h - d

d_pump = 18 ft - 17 ft

d_pump = 1 ft

Finally, we can calculate the work required to pump all of the oil to the surface using the formula:

Work (W) = Force * Distance

W = W_oil * d_pump

W = (30600π lb) * (1 ft)

W = 30600π lb·ft

Therefore, the work required to pump all of the oil to the surface is 30600π lb·ft (pound-foot).

(a) We need to evaluate the limit of the expression lim(x→0) (sin(4x) + x^3). To solve this limit, we can use basic limit properties and the fact that sin(x)/x approaches 1 as x approaches 0= 1/16.

First, we consider the limit of sin(4x) as x approaches 0. Using the property sin(x)/x → 1 as x → 0, we have sin(4x)/(4x) → 1 as x → 0. Since multiplying by a constant does not change the limit, we can rewrite this as (1/4)sin(4x)/(4x) → 1/4 as x → 0.

Next, we consider the limit of x^3 as x approaches 0. Since x^3 is a polynomial, the limit of x^3 as x approaches 0 is simply 0.

Therefore, by applying the limit properties and combining the limits, we have:

lim(x→0) (sin(4x) + x^3) = lim(x→0) (1/4)sin(4x)/(4x) + lim(x→0) x^3

= (1/4)(lim(x→0) sin(4x)/(4x)) + lim(x→0) x^3

= (1/4)(1/4) + 0

= 1/16

The force needed for a particle of mass m with the given position function is expressed as F(t) = 6mti + 14mj + 6mtk.

The force exerted on a particle with mass m, described by the position function r(t) = t³i + 7t²j + t³k,

To determine the force required for a particle with position function r(t) = t³i + 7t²j + t³k, we shall calculate the derivative of the position function with respect to time twice.

The force function is given by the second derivative of the position function:

F(t) = m * a(t)

where:

m = the mass of the particle

a(t) = the acceleration function.

Let's calculate:

First, we compute the velocity function by taking the derivative of the position function with respect to time:

v(t) = dr(t)/dt = d/dt(t³i + 7t²j + t³k)

= 3t²i + 14tj + 3t²k

Next, we find the acceleration function by taking the derivative of the velocity function with respect to time:

a(t) = dv(t)/dt = d/dt(3t²i + 14tj + 3t²k)

= 6ti + 14j + 6tk

Finally, to get the force function, we multiply the acceleration function by the mass of the particle:

F(t) = m * a(t)

= m * (6ti + 14j + 6tk)

Therefore, the force required for a particle of mass m with the given position function is F(t) = 6mti + 14mj + 6mtk.

The dimensions of the rectangular box are length (L), width (W), and height (H). The radius of the sphere inscribing the rectangular box is 8.

Let's assume the dimensions of the rectangular box are length (L), width (W), and height (H). Since the box is inscribed in a sphere, its longest diagonal will be equal to the diameter of the sphere, which is 2r (r is the radius of the sphere).

The surface area of the rectangular box can be calculated by summing the areas of its six faces: 2(LW + LH + WH) = 384.

The sum of the lengths of the 12 edges of the box is given as 4(L + W + H) = 112.

From these equations, we can solve for L + W + H = 28.

To find the radius of the inscribing sphere, we need to find the longest diagonal of the rectangular box. Using the Pythagorean theorem, the longest diagonal is √(L^2 + W^2 + H^2).

Since we have L + W + H = 28, we can substitute L + W = 28 - H into the equation for the longest diagonal: √((28 - H)^2 + H^2) = 2r.

By solving this equation, we find that H = 8.

Substituting this value into the equation L + W + H = 28, we get L + W = 20.

Finally, substituting L + W = 20 into the equation for the longest diagonal, we find √(20^2 + 8^2) = 2r.

Simplifying, we find r = 8.

Therefore, the radius of the sphere inscribing the rectangular box is 8.

The statement (d) "Not monotonic, bounded, and convergent" is true for the sequence defined as 12 + 22 + 32 + ... + (n + 2)2 = 2n2 + 11n + 15.

To determine if the sequence is monotonic, we need to analyze the difference between consecutive terms.

Taking the difference between consecutive terms, we get:

(2(n+1)^2 + 11(n+1) + 15) - (2n^2 + 11n + 15) = 4n + 13.

Since the difference between consecutive terms is 4n + 13, which is not a constant value, the sequence is not monotonic.

To check if the sequence is bounded, we examine the behavior of the terms as n approaches infinity. As n increases, the terms of the sequence grow without bound, as the leading term 2n^2 dominates.

Therefore, the sequence is not bounded.

Finally, since the sequence is not monotonic and not bounded, it cannot converge. Convergence requires the sequence to be both bounded and monotonic, which is not the case here.

Thus, the sequence defined as 12 + 22 + 32 + ... + (n + 2)2 = 2n^2 + 11n + 15 is not monotonic, bounded, or convergent.

To find the area of the region R bounded by the parabola y = 4[tex]x^{2}[/tex] and the line y = 1, we need to determine the points of intersection between these two curves.

First, let's set the equations equal to each other and solve for x:

The marginal cost represents the change in cost when one additional unit is produced. In the case of producing boxes of computer disks, the marginal cost is given as 8 + 90,000. To obtain the cost function, we integrate the marginal cost with respect to x. The integral of 8 with respect to x is 8x, and the integral of 90,000 with respect to x is 90,000x. Adding these two terms to the fixed cost of $150,000 gives us the cost function for producing x boxes of computer disks: C(x) = 8x + 90,000x + 150,000.

For producing rolls of film, the marginal cost is given as 6. To find the total cost function, we integrate this marginal cost with respect to x. The integral of 6 with respect to x is 6x.

To evaluate the line integral of F • dr along the straight line segment C from P to Q, where F(x, y) = -6x i + 5y j and P(-3, 2), Q(-5, 5), we need to parameterize the line segment C.

The parameterization of a line segment from P to Q can be written as r(t) = P + t(Q - P), where t ranges from 0 to 1.

In this case, P = (-3, 2) and Q = (-5, 5), so the parameterization becomes r(t) = (-3, 2) + t[(-5, 5) - (-3, 2)].

Simplifying, we have r(t) = (-3, 2) + t(-2, 3) = (-3 - 2t, 2 + 3t).

Now, we can calculate the differential dr as dr = r'(t) dt, where r'(t) is the derivative of r(t) with respect to t.

Taking the derivative of r(t), we get r'(t) = (-2, 3).

Therefore, dr = (-2, 3) dt.

Next, we evaluate F • dr along the line segment C by substituting the values of F and dr:

F • dr = (-6x, 5y) • (-2, 3) dt.

Substituting x = -3 - 2t and y = 2 + 3t, we have:

F • dr = [-6(-3 - 2t) + 5(2 + 3t)] • (-2, 3) dt.

Simplifying the expression, we get:

F • dr = (12t - 9) • (-2, 3) dt.

Finally, we integrate the scalar function (12t - 9) with respect to t over the range from 0 to 1:

∫(12t - 9) dt = [6t^2 - 9t] evaluated from 0 to 1.

Substituting the upper and lower limits, we have:

[6(1)^2 - 9(1)] - [6(0)^2 - 9(0)] = 6 - 9 = -3.

Therefore, the value of the line integral F • dr along the line segment C from P to Q is -3.

In order to determine the level of a two-sided confidence interval, we need to consider the given value of tn−1,α/2 and the sample size. The level of the confidence interval represents the degree of confidence we have in the estimate.

The confidence interval is calculated by taking the sample mean and adding or subtracting the margin of error, which is determined by the critical value tn−1,α/2 and the standard deviation of the sample. The critical value represents the number of standard deviations required to capture a certain percentage of the data.

The level of the confidence interval is typically expressed as a percentage and is equal to 1 minus the significance level. The significance level, denoted as α, represents the probability of making a Type I error, which is rejecting a true null hypothesis.

To find the level of the confidence interval, we can use the formula: level = 1 - α. The value of α is determined by the given value of tn−1,α/2, which corresponds to the desired confidence level and the sample size.

The point estimate for the mean (μ) is 89.1. The margin of error is 2.57, and the 95% confidence interval is from 86.53 to 91.67.

To find the confidence interval using the t-distribution, we first calculate the point estimate, which is the sample mean. In this case, the sample mean is given as x = 89.1.

Next, we need to determine the margin of error. The margin of error is calculated by multiplying the critical value from the t-distribution by the standard error of the mean. The critical value is determined based on the desired confidence level and the degrees of freedom, which in this case is n - 1 = 42 - 1 = 41. For a 95% confidence level, the critical value is approximately 2.021.

To calculate the standard error of the mean, we divide the sample standard deviation (s = 7.9) by the square root of the sample size (n = 42). The standard error of the mean is approximately 1.218.

The margin of error is then calculated as 2.021 * 1.218 = 2.57.

Finally, we construct the confidence interval by subtracting the margin of error from the point estimate to get the lower bound and adding the margin of error to the point estimate to get the upper bound. Therefore, the 95% confidence interval is (89.1 - 2.57, 89.1 + 2.57), which simplifies to (86.53, 91.67).

The global maximum value of f(x, y) is 241/2 and the global minimum value of f(x, y) is -235/2. The symbolic notation is: Maximum value = f(13/2, -13/2) = 241/2, Minimum value = f(-13/2, -13/2) = -235/2.

Given f(x, y) = 12x - 5y and the following inequalities: y ≥ x - 7, y ≥ -x - 7, y ≤ 6. To determine the global extreme values of f(x, y), we need to follow these steps:

Step 1: Find the critical points of f(x, y) by finding the partial derivatives of f(x, y) w.r.t x and y and equating them to zero. fₓ = 12, fᵧ = -5

Step 2: Equate the partial derivatives of f(x, y) to zero. 12 = 0 has no solution; -5 = 0 has no solution. Hence, there are no critical points for f(x, y).

Step 3: Find the boundary points of the region defined by the given inequalities. We have the following three lines:y = x - 7, y = -x - 7, y = 6where each of the three lines intersects with one or both of the other two lines, we get the corner points of the region: (-13/2, -13/2), (-13/2, 13/2), (13/2, 13/2), (13/2, -13/2).

Step 4: Evaluate f(x, y) at each of the four corner points. At (-13/2, -13/2), f(-13/2, -13/2) = 12(-13/2) - 5(-13/2) = -235/2At (-13/2, 13/2), f(-13/2, 13/2) = 12(-13/2) - 5(13/2) = -97At (13/2, 13/2), f(13/2, 13/2) = 12(13/2) - 5(13/2) = 65/2At (13/2, -13/2), f(13/2, -13/2) = 12(13/2) - 5(-13/2) = 241/2

The area bounded by the graphs of the equations x = 1, x = 2, and y = 0 is 1 square unit.

To find the general solution of the given differential equation, we start by separating the variables. The equation is:

sec(θ)tan(t) + 1 - ln|K(1+tan(1))|dy = 0.

Next, we integrate both sides with respect to y:

∫[sec(t)tan(t) + 1 - ln|K(1+tan(1))|]dy = ∫0dy.

The integral of 0 with respect to y is simply a constant, which we'll denote as C. Integrating the other terms, we have:

∫sec(t)tan(t)dy + ∫dy - ∫ln|K(1+tan(1))|dy = C.

The integral of dy is simply y, and the integral of ln|K(1+tan(1))|dy is ln|K(1+tan(1))|y. Thus, our equation becomes:

sec(t)tan(t)y + y - ln|K(1+tan(1))|y = C.

Factoring out y, we get:

y(sec(t)tan(t) + 1 - ln|K(1+tan(1))|) = C.

Dividing both sides by (sec(t)tan(t) + 1 - ln|K(1+tan(1))|), we obtain the general solution:

y = -ln|sec(t)| + ln|K(1+tan(1))| + C.

The answers are A. The limit of f(x) as (x approaches 0 is positive infinity and B. The function has a jump discontinuity at x = 0.

(a) To compute the limit of f(x) as x approaches 0, we substitute x = 0 into the function:

[tex]\[\lim_{x \to 0} f(x) = \lim_{x \to 0} \left(\frac{(x+10)^2 - 100}{x^2}\right)\][/tex]

Since both the numerator and denominator approach 0 as x approaches 0, we have an indeterminate form of [tex]\(\frac{0}{0}\)[/tex]. We can apply L'Hôpital's rule to find the limit. Differentiating the numerator and denominator with respect to x, we get:

[tex]\[\lim_{x \to 0} \frac{2(x+10)}{2x} = \lim_{x \to 0} \frac{x+10}{x} = \frac{10}{0}\][/tex]

The limit diverges to positive infinity, as the numerator approaches a positive value while the denominator approaches 0 from the right side. Therefore, the limit of f(x) as x approaches 0 is positive infinity.

(b) The function f(x) is not continuous at x = 0. This is because the limit of f(x) as x approaches 0 is not finite. The function has a vertical asymptote at x = 0 due to the division by [tex]x^2[/tex]. As x approaches 0 from the left side, the function approaches negative infinity, and as x approaches 0 from the right side, the function approaches positive infinity.

Therefore, the function has a jump discontinuity at x = 0.

To eliminate the parameter t in the given parametric equations x(t) = 8cos(t) and y(t) = 5sin(t), we can use trigonometric identities and algebraic manipulations .

To eliminate the parameter t and rewrite the parametric equations as a Cartesian equation, we start by using the trigonometric identity cos²(t) + sin²(t) = 1. From the given parametric equations x(t) = 8cos(t) and y(t) = 5sin(t), we can square both equations:

x²(t) = 64cos²(t)

y²(t) = 25sin²(t)

Adding these two equations together, we obtain:

x²(t) + y²(t) = 64cos²(t) + 25sin²(t)

Now, we can substitute the trigonometric identity into the equation:

x²(t) + y²(t) = 64(1 - sin²(t)) + 25sin²(t)

Simplifying further, we have:

x²(t) + y²(t) = 64 - 64sin²(t) + 25sin²(t)

x²(t) + y²(t) = 64 - 39sin²(t)

This is the Cartesian equation that represents the given parametric equations after eliminating the parameter t. It relates the x and y coordinates without the need for the parameter t.

The parametric equation of the line passing through point A(4, -5, -2) and normal to the plane -2x - y + 3 = 8 is x = 4 - 2t, y = -5 + t, z = -2 + 3t. The symmetric equation of the line is (x - 4) / -2 = (y + 5) / 1 = (z + 2) / 3.

To find the parametric equation of the line passing through point A and normal to the given plane, we first need to find the direction vector of the line.

The direction vector of a line normal to the plane is the normal vector of the plane.

The given plane has the equation -2x - y + 3 = 8.

We can rewrite it as -2x - y + 3 - 8 = 0, which simplifies to -2x - y - 5 = 0.

The coefficients of x, y, and z in this equation represent the components of the normal vector of the plane.

Therefore, the normal vector is N = (-2, -1, 0).

Now, we can write the parametric equation of the line using the point A(4, -5, -2) and the direction vector N.

Let t be a parameter representing the distance along the line.

The parametric equations are:

x = 4 - 2t

y = -5 - t

z = -2 + 0t (since the z-component of the direction vector is 0)

Simplifying these equations, we obtain:

x = 4 - 2t

y = -5 + t

z = -2

These equations represent the parametric equation of the line passing through A and normal to the given plane.

To find the symmetric equation of the line, we can rewrite the parametric equations in terms of ratios:

(x - 4) / -2 = (y + 5) / 1 = (z + 2) / 0

However, since the z-component of the direction vector is 0, we can ignore it in the equation.

Therefore, the symmetric equation becomes:

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

This is the symmetric equation of the line passing through A and normal to the given plane.

The limit of tanh(x) as x approaches infinity or negative infinity is 1 and -1, respectively. The derivative of f(x) = tanh(Vx+) + 4 is f'(x) = Vsech²(Vx+) where sech(x) is the hyperbolic secant function.

To find the absolute maximum and minimum values of f(x) on a given interval, we need to analyze the critical points and endpoints of the interval.

The hyperbolic tangent function, tanh(x), is defined as (e^x - e^(-x))/(e^x + e^(-x)). As x approaches positive infinity, both the numerator and denominator of the fraction approach infinity, resulting in a limit of 1.

Similarly, as x approaches negative infinity, the numerator and denominator approach negative infinity, giving a limit of -1.

Therefore, the limit of tanh(x) as x approaches infinity or negative infinity is 1 and -1, respectively.

To find the derivative of f(x) = tanh(Vx+) + 4, we can use the chain rule. The derivative of tanh(x) is sech²(x), where sech(x) is the hyperbolic secant function defined as 1/cosh(x).

Applying the chain rule, we get f'(x) = Vsech²(Vx+).

This derivative represents the rate of change of the function f(x) with respect to x.

To determine the absolute maximum and minimum values of f(x) on a given interval, we need to consider the critical points and endpoints of the interval. The critical points occur where the derivative is either zero or undefined. In this case, since the derivative f'(x) = Vsech²(Vx+), the critical points occur where sech²(Vx+) = 0. However, sech²(x) is always positive, so there are no critical points.

Next, we examine the endpoints of the given interval. If the interval is bounded, we evaluate f(x) at the endpoints and compare the values to determine the absolute maximum and minimum. If the interval is unbounded, as x approaches positive or negative infinity, f(x) approaches 4. Therefore, the absolute maximum and minimum values of f(x) on the given interval are both 4.

To determine values for c and d such that the function is continuous everywhere, we need more information about the function itself.

The provided expression "1+1 3. d I=3" seems to contain a typographical error or is incomplete, making it difficult to provide a specific solution.However, I can provide a general explanation of continuity and how to find values for c and d to ensure continuity. (1 point) Continuity of a function means that the function is uninterrupted or "smooth" throughout its domain, without any abrupt jumps or breaks. In order to ensure continuity, we need to satisfy three conditions:

The function must be defined at every point in its domain. The limit of the function as x approaches a particular value must exist. The value of the function at that point must be equal to the limit. Without a specific function, it is challenging to provide a detailed solution. However, in general, to determine values for c and d that make a function continuous, we typically consider the following steps: Start by examining the given function and identifying any points where it is undefined or has potential discontinuities, such as vertical asymptotes, holes, or jumps.

If the function has a vertical asymptote at a certain value of x, we need to ensure that the limit of the function as x approaches that value exists. If the limit exists, we adjust the function's value at that point to match the limit. If the function has a hole at a specific x-value, we can fill the hole by simplifying the expression and canceling common factors. If the function has a jump at a particular x-value, we need to determine the left-hand limit and the right-hand limit as x approaches that value. The function is continuous if the left-hand limit, right-hand limit, and the value of the function at that point are all equal. By carefully analyzing the given function and following these steps, you can find suitable values for c and d that make the function continuous throughout its domain.

The directional derivative of f at P in the direction of v is 3. The maximum rate of change of f at P is 3, which occurs in the direction of the vector w = (3/√10)i + (1/√10)j.

The directional derivative of a function f at a point P in the direction of a vector v is given by the dot product of the gradient of f at P and the unit vector in the direction of v. In this case, the gradient of f is given by (∂f/∂x, ∂f/∂y) = (y, x), so the gradient at P is (−3, 0). The unit vector in the direction of v is (3/√10, 1/√10). Taking the dot product of the gradient and the unit vector gives (−3)(3/√10) + (0)(1/√10) = −9/√10 = −3/√10. Therefore, the directional derivative of f at P in the direction of v is 3.

To find the maximum rate of change of f at P, we need to find the magnitude of the gradient of f at P. The magnitude of the gradient is given by √(∂f/∂x)^2 + (∂f/∂y)^2 = √(y^2 + x^2). Substituting P into the expression gives √((-3)^2 + 0^2) = 3. Therefore, the maximum rate of change of f at P is 3.

To find the unit direction vector w in which the maximum rate of change occurs at P, we divide the gradient vector at P by its magnitude. The gradient at P is (−3, 0), and its magnitude is 3. Dividing each component by 3 gives the unit vector (−1, 0). Thus, the unit direction vector w in which the maximum rate of change occurs at P is w = (−1, 0).

8. the given pair of planes are neither parallel nor orthogonal.

9. an equation of the plane parallel to 2x + y - z = 1 and passing through a specific point (x₀, y₀, z₀) is: 2x + y - z = 2x₀ + y₀ - z₀

8.To determine if the given pair of planes are parallel, orthogonal, or neither, we can compare their normal vectors. The normal vector of a plane is the coefficients of x, y, and z in the equation of the plane.

The equation of the first plane is 2x + 2y - 3z = 10. Its normal vector is [2, 2, -3].

The equation of the second plane is -10x - 10y + 15z = 10. Its normal vector is [-10, -10, 15].

To determine the relationship between the planes, we can check if the normal vectors are parallel or orthogonal.

For two vectors to be parallel, they must be scalar multiples of each other. In this case, the normal vectors are not scalar multiples of each other, so the planes are not parallel.

For two vectors to be orthogonal (perpendicular), their dot product must be zero. Let's calculate the dot product of the normal vectors:

[2, 2, -3] ⋅ [-10, -10, 15] = (2 * -10) + (2 * -10) + (-3 * 15) = -20 - 20 - 45 = -85

Since the dot product is not zero, the planes are not orthogonal either.

Therefore, the given pair of planes are neither parallel nor orthogonal.

9. To find an equation of the plane parallel to 2x + y - z = 1 and passing through a specific point, we need both the normal vector and a point on the plane.

The equation 2x + y - z = 1 can be rewritten in the form of Ax + By + Cz = D, where A = 2, B = 1, C = -1, and D = 1. Therefore, the normal vector of the plane is [A, B, C] = [2, 1, -1].

Let's assume we want the plane to pass through the point P(x₀, y₀, z₀).

Using the point-normal form of the equation of a plane, the equation of the desired plane is: 2(x - x₀) + 1(y - y₀) - 1(z - z₀) = 0

Simplifying, we get:

2x + 1y - z - (2x₀ + y₀ - z₀) = 0

The coefficients of x, y, and z in the equation represent the normal vector of the plane.

Therefore, an equation of the plane parallel to 2x + y - z = 1 and passing through a specific point (x₀, y₀, z₀) is:

2x + y - z = 2x₀ + y₀ - z₀

The value of ∫₁₄ x f''(x) dx after integration is 6.

The summing of discrete data is indicated by the integration. To determine the functions that will characterise the area, displacement, and volume that result from a combination of small data that cannot be measured separately, integrals are calculated.

To find the value of ∫₁₄ x f''(x) dx, we can use integration by parts. Let's start by applying the integration by parts formula:

∫ u dv = uv - ∫ v du

In this case, we will let u = x and dv = f''(x) dx. Therefore, du = dx and v = ∫ f''(x) dx.

Integrating f''(x) once gives us f'(x), so v = ∫ f''(x) dx = f'(x).

Now, applying the integration by parts formula:

∫₁₄ x f''(x) dx = x f'(x) - ∫ f'(x) dx

We can evaluate the integral on the right-hand side using the given values of f'(1) and f'(4):

∫ f'(x) dx = f(x) + C

Evaluating f(x) at 4 and 1:

∫ f'(x) dx = f(4) - f(1)

Using the given values of f(1) and f(4):

∫ f'(x) dx = 8 - 2 = 6

Now, substituting this into the integration by parts formula:

∫₁₄ x f''(x) dx = x f'(x) - ∫ f'(x) dx

                  = x f'(x) - (f(4) - f(1))

                  = x f'(x) - 6

Using the given values of f'(1) and f'(4):

∫₁₄ x f''(x) dx = x f'(x) - 6

               = x (3) - 6  (since f'(1) = 3)

               = 3x - 6

Now, we can evaluate the definite integral from 1 to 4:

∫₁₄ x f''(x) dx = [3x - 6]₁₄

               = (3 * 4 - 6) - (3 * 1 - 6)

               = 6

Therefore, the value of ∫₁₄ x f''(x) dx is 6.
