Answers

Answer 1

The expression for ∂z/∂t, as given by the chain rule, has three terms.

Here's how to derive the expression for ∂z/∂t:

According to the chain rule of differentiation, we have:

[tex]$\frac{dz}{dt}=\frac{\partial z}{\partial u}\frac{\partial u}{\partial x}\frac{\partial x}{\partial t}+\frac{\partial z}{\partial u}\frac{\partial u}{\partial y}\frac{\partial y}{\partial t}+\frac{\partial z}{\partial v}\frac{\partial v}{\partial x}\frac{\partial x}{\partial t}+\frac{\partial z}{\partial v}\frac{\partial v}{\partial y}\frac{\partial y}{\partial t}+\frac{\partial z}{\partial t}$[/tex]

Here, we can see that the expression for ∂z/∂t has five terms.

The first four terms represent the changes in z due to changes in u and v, which are dependent on x and y, which are themselves dependent on t and s.

The last term represents the change in z directly due to changes in t.

However, if we assume that z does not depend explicitly on t, then the last term will be zero, and the expression for ∂z/∂t will have three terms.

Hence, the expression for ∂z/∂t, as given by the chain rule, has three terms.

Compute the surface annular pressure that would be observed if the kick was methane gas and the annular capacity was 0.1667 bbl/ft instead of 0.0775 bbl/ft. Assume the gas density is negligible. Answer: 684 psig.

Answers

The shut-in drillpipe and casing pressure that would be observed after the kick entered the well is 785 psig and 806 psig, respectively.

To calculate the shut-in drillpipe pressure, we can use the following formula: Shut-in drillpipe pressure = Formation pressure + (Annular capacity opposite drillpipe * Kick height inside drillpipe * Kick density)

Given that the formation pressure is 6,000 psia and the annular capacity opposite the drillpipe is 0.01776 bbl/ft, we need to determine the kick height inside the drillpipe and the kick density.

The kick height inside the drillpipe can be calculated by subtracting the height of the drill collars (600 ft) from the total well depth (10,000 ft). So, the kick height inside the drillpipe is 9,400 ft.

The kick density is the density of the saltwater influx, which is 9.0 lbm/gal.

Substituting the values into the formula, we get:

Shut-in drillpipe pressure = 6,000 psia + (0.01776 bbl/ft * 9,400 ft * 9.0 lbm/gal) = 785 psig

To calculate the shut-in casing pressure, we can use the following formula: Shut-in casing pressure = Formation pressure + (Annular capacity opposite casing * Kick height inside casing * Kick density)

Given that the annular capacity opposite the casing is 0.0500 bbl/ft and the kick height inside the casing is 9,400 ft, we can substitute the values into the formula:

Shut-in casing pressure = 6,000 psia + (0.0500 bbl/ft * 9,400 ft * 9.0 lbm/gal) = 806 psig

Therefore, the shut-in drillpipe pressure is 785 psig and the shut-in casing pressure is 806 psig.

What is an example of an infinite geometric series in real life? Think of a bouncing ball. A fist of heights of each bounce of ball can be thought of as a geometric sequence. If the ball continues to bounce, the sum of these decreasing heights is a series. The values you enter in this part will be used to make later calculations. While tossing around a ball one day, you notice that when you drop the ball, the rebound height is always less than the previous height. You decide to determine the total distance the ball travels. From what height, in feet, do you initially drop the ball? Each rebound is approwimately what portion of the previous height? (Enter a fraction or an exact decimal.)

Answers

The initial height from where the ball is dropped is x = h₁= 5 / 2 ft.

An example of an infinite geometric series in real life can be the bouncing of a ball. When a ball bounces on the ground, it reaches to some height, let’s call it h₁. Then it comes back to the ground and bounces again, reaching to some height, let’s call it h₂.

We can see that the ratio of the heights of the bounces is constant or the same throughout the bouncing process, so it's a geometric sequence.

An infinite geometric series is a series where the ratio between consecutive terms remains constant, and the sum of an infinite number of terms is defined.

The formula to calculate the sum of the infinite geometric series is given by:

S= a₁ / (1-r)

where S is the sum of the infinite series,

a₁ is the first term of the sequence,

and r is the common ratio of the sequence.

Let's solve the given problem. We need to find the initial height from where the ball is dropped and also find each rebound that is approximately what portion of the previous height. So, the initial height from where the ball is dropped is h₁. Let the first bounce height be x ft and the ratio of the height of each consecutive bounce be r.

Then the second bounce height will be x(r) ft, the third bounce height will be x(r)^2 ft, and so on. Therefore, h₁ = x

The fraction by which the height of the ball decreases at each bounce is given as r.

So, h₂ = x(r), h₃ = x(r)^2, and so on. Let the sum of all distances traveled by the ball be S.

Therefore, the total distance traveled by the ball = S + h₁. Since the ball bounces to an infinite number of times, it is an infinite geometric series. The sum of the infinite geometric series is given as,

S = a₁ / (1-r) where a₁ = h₂ and r = fraction by which the height of the ball decreases at each bounce.

Then S = x(r) / (1-r)

Total distance traveled = S + h₁ = x / (1-r) + x

Now we will substitute the values and solve.

Total distance traveled by the ball = x / (1 - 3/4) + x= 4x + x = 5x

We are given that the rebound height is always less than the previous height. So, the fraction by which the height of the ball decreases at each bounce is 3/4.

Approximately 75% of the previous height of the ball is the height of the next bounce. Therefore, the initial height from where the ball is dropped is x = h₁= 5 / 2 ft.

a) Producer surplus when the selling price is $600 is $9600.

b) Consumer surplus if the shirts are sold for $13 each is $1368.

Given: Supply curve is modeled by the equation p = 200 + 0.4q3/2

(a) Producer surplus when the selling price is $600

Producer Surplus is defined as the difference between what the producer gets from selling their product and the minimum amount that they were willing to accept for the product.

For the given supply curve, the producer surplus can be calculated as follows:

Selling price of T-shirt = $600

For a given quantity, q, the supply curve equation can be used to calculate the price, p.

Substituting q = Q in the supply equation, we get

P = 200 + 0.4Q3/2

(b) Consumer surplus if the shirts are sold for $13 each

The Consumer Surplus is defined as the difference between the maximum amount that the consumer is willing to pay for a product and the actual price that they pay for it.

Given, the price of the T-Shirt, p = $13

For a given quantity, q, the demand curve equation can be used to calculate the price, p.

Substituting p = $13 in the demand equation, we get

13 = 80 – 2Q

Construct Parametric Equation Describing The Graph Of The Line With The Following Attributes. Slope =5 And Passing Through

Answers

To construct a parametric equation describing the graph of the line with the following attributes, slope = 5 and passing through a point, use the following steps:

Let the point that the line passes through be (x1, y1).

Therefore, the point-slope form of the line can be written as y - y1 = m(x - x1)where m is the slope of the line. Rearranging this equation gives us:y = mx + (y1 - mx1)

Therefore, we can define the parametric equations for x and y as follows:x = t + x1y = 5t +y where t is the parameter. This results in the parametric equation describing the graph of the line with the following attributes, slope = 5 and passing through a point (x1, y1):x = t + x1y = 5t + y1

y"-2y" - 4y + 8y = 0 The characteristic equation for this differential equation is given by:

r² - 2r - 4 = 0.

The characteristic equation has the roots:

r = (2±√4+16)/2r

r = 1±2i Therefore, the general solution of the differential equation is given by:

y(t) = e^(r₁*t)(C₁) + e^(r₂*t)(C₂)y(t)

where, A is an arbitrary constant, and c1 and c2 are constants.

Given differential equation:

y'' - 2y' - 4y + 8y = 0

For finding the general solution of the differential equation, we need to first find the characteristic equation of the given differential equation.

The characteristic equation of the given differential equation is as follows:

r² - 2r - 4 = 0

Solving the above quadratic equation by quadratic formula, we get:

r = [2 ± √(2² + 4(4))] / 2

= [2 ± √(20)] / 2

= [2 ± 2√5] / 2

= 1 ± √5

Therefore, the complementary function is given by:

yc = c1 * e^(1*t) + c2 * e^(-1*t)

Where, c1 and c2 are arbitrary constants.

Now, we need to find the particular solution of the given differential equation.

For that, we assume the particular solution to be of the form of yp = A * y

where, A is an arbitrary constant, and y is the complementary function of the given differential equation.

Therefore, yp = A * yc = A * [c1 * e^(1*t) + c2 * e^(-1*t)]

Multiplying both sides of the given differential equation by e^(2t),

we get:e^(2t) * y'' - 2e^(2t) * y' - 4e^(2t) * y + 8e^(2t) * y = 0

Differentiating the above expression with respect to t, we get:

e^(2t) * y''' - 2e^(2t) * y'' - 4e^(2t) * y' + 8e^(2t) * y' - 8e^(2t) * y = 0

e^(2t) * y''' - 2e^(2t) * y'' + 4e^(2t) * y' - 8e^(2t) * y = 0

Adding this equation to the given differential equation, we get:

e^(2t) * y''' + 2e^(2t) * y' - 8e^(2t) * y = 0

Let, yp = A * yc = A * [c1 * e^(1*t) + c2 * e^(-1*t)]

Substituting this value in the above equation, we get:

e^(2t) * A * yc''' + 2e^(2t) * A * yc' - 8e^(2t) * A * yc = 0e^(2t) * A * [yc''' + 2yc' - 8yc] = 0

e^(2t) * A * [c1 * e^(1*t) + c2 * e^(-1*t)]''' + 2e^(2t) * A * [c1 * e^(1*t) + c2 * e^(-1*t)]' - 8e^(2t) * A * [c1 * e^(1*t) + c2 * e^(-1*t)] = 0

Now, we can calculate the derivative of yc''' + 2yc' - 8yc as follows:

yc' = c1 * e^(1*t) - c2 * e^(-1*t)yc'' = c1 * e^(1*t) + c2 * e^(-1*t)yc''' = c1 * e^(1*t) - c2 * e^(-1*t)

Substituting these values in the above equation, we get:

e^(2t) * A * [(c1 * e^(1*t) - c2 * e^(-1*t)) + 2(c1 * e^(1*t) - c2 * e^(-1*t)) - 8(c1 * e^(1*t) + c2 * e^(-1*t))] = 0e^(2t) * A * [(3c1 - 6c2) * e^(1*t) + (-6c1 + 3c2) * e^(-1*t)] = 0

As e^(2t) is not equal to zero for all t, therefore,

(3c1 - 6c2) * e^(1*t) + (-6c1 + 3c2) * e^(-1*t) = 0

Comparing the coefficients of e^(1*t) and e^(-1*t), we get:

3c1 - 6c2 = 0-6c1 + 3c2 = 0

Solving these two equations, we get: c1 = 2c2

Substituting the value of c1 in terms of c2 in the complementary function, we get:

yc = c2 * e^(-t) + 2c2 * e^(t)

The general solution of the given differential equation is given by:

y(t) = yc + yp = c2 * e^(-t) + 2c2 * e^(t) + A * [c1 * e^(1*t) + c2 * e^(-1*t)]

To elaborate, the minute hand of a clock rotates around the entire clock face, completing one full revolution in 60 minutes. On the other hand, the hour hand moves more slowly and completes one revolution in 12 hours.

At 7:30, the hour hand would be pointing halfway between the 7 and 8 o'clock positions, which is an angle of π/4 radians (or 45 degrees) from the 7 o'clock position. Meanwhile, the minute hand would be pointing directly at the 6 o'clock position, creating another angle of π/2 radians (or 90 degrees) with respect to the 12 o'clock position.

The angle between the two hands can be determined by calculating the difference between their respective angles from the 12 o'clock position. Since the hour hand is halfway between 7 and 8, its angle from the 12 o'clock position would be 7/12 multiplied by 2π radians (a complete circle), which equals π/2 + π/6 radians. The minute hand, being at the 6 o'clock position, has an angle of π radians from the 12 o'clock position. Therefore, the angle between the two hands would be the absolute difference between these two angles, which is |(π/2 + π/6) - π| = π/4 radians (or 45 degrees).

This indicates that the y-intercept is probably close to zero.
The graph of the continuous exponential function f(x) with the given values of x and f(x) shows a curve that is increasing rapidly as x increases.

This indicates that the function is an exponential growth function with a base greater than 1.The equation for an exponential growth function with base b and initial value a is given by:

Answers

The size of the population after 3 months is approximately 129.3.

(a) Here's how to derive the formula for the population size after t months, given that the population is 5000 at t=0:

                               P'(t) = 200te^{-5t^2}P(t) = ∫P'(t) dt + C; (C is the constant of integration)

                      [tex]P(t) = ∫200te^{-5t^2} dt + CP(t) = -\frac{40}[/tex]

    [tex]{\sqrt{5\pi}}e^{-5t^2} + CP(0) = 5000;[/tex]

since population is 5000 at t=0, we can substitute that into the formula above to get

                          [tex]5000 = -\frac{40}{\sqrt{5\pi}}e^{0} + C5000[/tex]

               = [tex]= -\frac{40}{\sqrt{5\pi}} + C5000 + \frac{40}{\sqrt{5\pi}}[/tex]

      = [tex]= CC = \frac{50000}{\sqrt{5\pi}}[/tex]

Substitute C = \frac{50000}{\sqrt{5\pi}} into the formula for P(t) above:

                 [tex]P(t) = -\frac{40}{\sqrt{5\pi}}e^{-5t^2} + \frac{50000}{\sqrt{5\pi}}[/tex]

(a) [tex]P(t) = -\frac{40}{\sqrt{5\pi}}e^{-5t^2} + \frac{50000}{\sqrt{5\pi}}[/tex]

(b) To find the size of the population after 3 months, substitute t = 3 into the formula derived in part (a):

                      [tex]P(3) = -\frac{40}{\sqrt{5\pi}}e^{-5(3^2)} + \frac{50000}{\sqrt{5\pi}}[/tex]

                 [tex]P(3) = -\frac{40}{\sqrt{5\pi}}e^{-45} + \frac{50000}{\sqrt{5\pi}}P(3) ≈ 129.3 (rounded off to one decimal place).[/tex]

Thus, the size of the population after 3 months is approximately 129.3.

1. Combine the following over a single denominator. a) + xy b) + 2x 2. Explain why you could not simplify the following fraction as displayed - = 3x+4y 3x+4y = 4y 3* 3x

Answers

The sum of [tex]\(\frac{a}{xy} + \frac{b}{2x}\)[/tex] can be combined over a single denominator as follows: [tex]\(\frac{2a + by}{2xy}\)[/tex].

To simplify the fraction [tex]\(\frac{3x+4y}{3x+4y}\)[/tex], we cannot directly reduce it to [tex]\(\frac{4y}{3}\)[/tex] because it results in dividing the numerator by 3x instead of just 3. This is due to the fact that the terms 3x and 4y are being added in both the numerator and denominator. Thus, the terms cannot be cancelled out completely.

To understand this, let's simplify the fraction step by step:

[tex]\[\frac{3x+4y}{3x+4y} = \frac{(3x+4y)}{(3x+4y)} \][/tex]

Since the numerator and denominator are identical, the fraction is equal to 1. However, it cannot be simplified further because there is no common factor that can be cancelled out. If we try to cancel 3x in the numerator with the 3x in the denominator, we would be left with [tex]\(\frac{4y}{1}\)[/tex], which is not equivalent to the original fraction. Therefore, the fraction remains as [tex]\(\frac{3x+4y}{3x+4y}\)[/tex].

Answers

The explicit method and Crank-Nicolson methods give different numerical solutions for the parabolic PDE with the given initial and boundary conditions.

The equation is a parabolic partial differential equation with the initial and boundary conditions being given by:

u(x, 0) = sin(x)

for 0 ≤ x ≤ 1

u(0, t) = u(1, t) = 0

for t > 0

For the explicit method, the finite difference equation is given by:

U(i, j+1) = St*(U(i-1, j) - 2*U(i, j) + U(i+1, j))/(dx*dx) + U(i, j)

where, U(i, j) ≈ u(i*dx, j*St) is the numerical solution at (i, j)th mesh point, St = 0.001 is the time-step size, and dx = 0.1 is the mesh size. For the numerical solution, we need to compute two time-steps, i.e., j = 0, 1.

Therefore, we have U(i, 1) = St*(U(i-1, 0) - 2*U(i, 0) + U(i+1, 0))/(dx*dx) + U(i, 0)

After substitution, the explicit method gives the following numerical solutions:

U(1, 1) = 0.000000

U(2, 1) = 0.001238

U(3, 1) = 0.002456

U(7, 1) = 0.003834

U(8, 1) = 0.003150

U(9, 1) = 0.002353

U(10, 1) = 0.001607

For the Crank-Nicolson method, the finite difference equation is given by:

U(i, j+1) - U(i, j) = 0.5*St*(U(i-1, j+1) - 2*U(i, j+1) + U(i+1, j+1) + U(i-1, j) - 2*U(i, j) + U(i+1, j))/(dx*dx)

where, U(i, j) ≈ u(i*dx, j*St) is the numerical solution at (i, j)th mesh point, St = 0.001 is the time-step size, and dx = 0.1 is the mesh size.

We need to compute two time-steps, i.e., j = 0, 1.

Using the iterative method to solve the finite difference equation, we get the following numerical solutions:

U(1, 1) = 0.000000

U(2, 1) = 0.000585

U(3, 1) = 0.001160

U(4, 1) = 0.001626

U(5, 1) = 0.001924

U(6, 1) = 0.001995

U(7, 1) = 0.001828

U(8, 1) = 0.001460

U(9, 1) = 0.001006

2. a) Under the mapping \( w=\frac{1}{z} \), Find the image for \( x^{2}+y^{2}=9 \)

Answers

The image of the circle [tex]\(x^2 + y^2 = 9\)[/tex] under the mapping [tex]\(w = \frac{1}{z}\)[/tex] is given by the parametric equations:

[tex]\(x = \frac{u}{1 - u^2} \cdot \left(\frac{1}{-2vuy + u^2v - 1}\right)^2\)\\\(y = \frac{1}{-2vuy + u^2v - 1}\)[/tex]

To obtain the image of the circle [tex]\(x^2 + y^2 = 9\)[/tex] under the mapping [tex]\(w = \frac{1}{z}\)[/tex], we substitute z = x + yi into the equation and express it in terms of w.

Provided the equation [tex]\(x^2 + y^2 = 9\)[/tex], let's solve it for [tex]\(y^2\)[/tex]:

[tex]\(y^2 = 9 - x^2\)[/tex]

Substituting z = x + yi and rearranging, we get:

[tex]\(|z|^2 = 9\)\\\(x^2 + y^2 = 9\)[/tex]

Using the mapping [tex]\(w = \frac{1}{z}\)[/tex], we substitute z = x + yi and w = u + vi into the equation:

[tex]\(\frac{1}{z} = w\)\\\(\frac{1}{x + yi} = u + vi\)[/tex]

To simplify this, we multiply the numerator and denominator by the complex conjugate of (x + yi):

[tex]\(\frac{1}{x + yi} = \frac{x - yi}{(x + yi)(x - yi)}\) \(= \frac{x - yi}{x^2 + y^2}\) \( = \frac{x}{x^2 + y^2} - \frac{y}{x^2 + y^2}i\)[/tex]

Comparing the real and imaginary parts, we have:

[tex]\(u = \frac{x}{x^2 + y^2}\) , \(v = -\frac{y}{x^2 + y^2}\)[/tex]

Now, we need to express x and y in terms of u and v.

Let's solve the equations for x and y:

[tex]\(u = \frac{x}{x^2 + y^2}\) , \ v = -\frac{y}{x^2 + y^2}\)[/tex]

Rearranging the first equation:

[tex]\(ux^2 + uy^2 = x\)\(x - ux^2 = uy^2\)\\\(x(1 - u^2) = uy^2\)\\\(x = \frac{uy^2}{1 - u^2}\)[/tex]

Rearranging the second equation:

[tex]\(-v(x^2 + y^2) = y\)\\\(-v\left(\frac{uy^2}{1 - u^2} + y^2\right) = y\)\\\(-vuy^2 - vy^2 + (u^2v - 1)y^2 = y\)\\\((-vuy^2 + (u^2v - 1)y^2) + vy^2 - y = 0\)\\\((-vuy^2 + (u^2v - 1)y^2) + y(vy - 1) = 0\)\\\(y(-vuy + (u^2v - 1)y + vy - 1) = 0\)[/tex]

Since we are dealing with a circle, y cannot be zero.

Therefore, the expression in the parentheses must be zero:

[tex]\(-vuy + (u^2v - 1)y + vy - 1 = 0\)\\\((-2vuy + u^2v - 1)y = 1\)\\\(y = \frac{1}{-2vuy + u^2v - 1}\)[/tex]

Substituting this value of y into the expression for x:

[tex]\(x = \frac{uy^2}{1 - u^2}\)\\\(x = \frac{u}{1 - u^2} \cdot \left(\frac{1}{-2vuy + u^2v - 1}\right)^2\)[/tex]

Hence,  [tex]x = \frac{u}{1 - u^2} \cdot \left(\frac{1}{-2vuy + u^2v - 1}\right)^2\)[/tex] and [tex]y = \frac{1}{-2vuy + u^2v - 1}\)[/tex]

Find the 6th Details term of the geometric sequence: -9, 31.5,- 110.25,...

Answers

The 6th term of the geometric sequence is approximately 4726.96875.

The common ratio (r) is found by dividing any term in the sequence by its preceding term. Let's divide the second term (-9) by the first term (31.5):

r = 31.5 / (-9) = -3.5

Now that we know the common ratio (r = -3.5), we can find the 6th term using the formula:

term = first term * (common ratio)^(n - 1)

where n is the position of the term in the sequence.

For the 6th term, we have:

term = -9 * (-3.5)^(6 - 1)

= -9 * (-3.5)^5

Evaluating this expression, we find:

term ≈ -9 * (-525.21875)

cos=-1/(sqrt(2)) at (3pi)/4

Answers

The exact angle at which cos equals -1/√2 at (3π)/4 is **(5π)/4**.

To find the value of cos at (3π)/4, we can use the unit circle and trigonometric identities.

The given value is cos = -1/√2. Since the unit circle represents the values of cos and sin for different angles, we can determine the angle at which cos equals -1/√2.

In the unit circle, cos is negative in the second and third quadrants.

Since the given value is negative, we know that the angle (3π)/4 falls in either the second or third quadrant.

To find the exact angle, we can use the reference angle. The reference angle for (3π)/4 is π/4.

Since cos is negative at (3π)/4, it means that the terminal side of the angle intersects the x-axis to the left of the unit circle.

Therefore, the exact angle at which cos equals -1/√2 at (3π)/4 is **(5π)/4**.

It's important to note that the value of cos is periodic, and there are infinitely many angles that yield the same cosine value. In this case, (5π)/4 is one such angle.

Answers

The value of c for which the solution satisfies the initial condition y(3) = 8 is given by c = −sin 3 (sin 3 + cos 3).

a) Find the general solution to the differential equation: y′ = cos x e sin x

We have the differential equation:

y′ = cos x e sin x

By separation of variables, we have:

dy/dx = cos x e sin x

⇒ dy = cos x e sin x dx

Integrating both sides, we get:

∫dy = ∫cos x e sin x dx

⇒ y = e sin x (sin x + cos x) + C, where C is a constant of integration.

The general solution to the differential equation is y = e sin x (sin x + cos x) + C, where C is a constant of integration.

b) Verify that the function y = x² + x²c is a solution of the differential equation xy′ + 2y = 4x², (x > 0)

To verify that the function y = x² + x²c is a solution of the differential equation xy′ + 2y = 4x²,

we need to substitute y into the differential equation and check if it satisfies it or not.

We have the differential equation:

xy′ + 2y = 4x²

Substituting y = x² + x²c into the above equation, we get:

x(xy′ + 2y) = x(2x + 2cx²) = 4x²

⇒ xy′ + 2y = 4

⇒ x(2cx/x + 2x/x) = 4

⇒ 2c + 2 = 4

⇒ c = 1

Therefore, the function y = x² + x²c

= x² + x²(1)

= x² + x² is a solution of the differential equation xy′ + 2y = 4x². We have c = 1.

c) Find the value of c for which the solution satisfies the initial condition y(3) = 8.

To find the value of c for which the solution satisfies the initial condition y(3) = 8,

we need to substitute x = 3 and y = 8 into the general solution obtained in part (a) and solve for c.

We have:

y = e sin x (sin x + cos x) + C

Substituting x = 3 and y = 8, we get:

8 = e sin 3 (sin 3 + cos 3) + C

⇒ C = 8 − e sin 3 (sin 3 + cos 3)

Substituting this value of C back into the general solution, we get:

y = e sin x (sin x + cos x) + 8 − e sin 3 (sin 3 + cos 3)

Therefore, the value of c for which the solution satisfies the initial condition y(3) = 8 is given by c = −sin 3 (sin 3 + cos 3).

Find the absolute maximum and minimum of the function f(x)= x¹/3(x²-9) for [-4,2] Express your answers in simple exact form.

Answers

Therefore, the absolute maximum of the function f(x) on the interval [-4, 2] is 0, and the absolute minimum is -8√2.

1. Critical points:

To find the critical points, we need to find the values of x where the derivative of the function is either zero or undefined.

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

f'(x) = (1/3)x^(-2/3)(x^2 - 9) + x^(1/3)(2x)

Setting f'(x) = 0 to find the critical points:

(1/3)x^(-2/3)(x^2 - 9) + x^(1/3)(2x) = 0

Simplifying the equation:

(x^2 - 9) + 3x(x^2 - 9) = 0

(x^2 - 9)(1 + 3x) = 0

From this equation, we find two critical points:

x = -3 and x = 3.

2. Endpoints:

The function is defined on the interval [-4, 2], so we need to evaluate f(x) at x = -4 and x = 2.

Now, let's evaluate the function at the critical points and endpoints:

f(-4) = (-4)^(1/3)((-4)^2 - 9) = -8√2

f(-3) = (-3)^(1/3)((-3)^2 - 9) = 0

f(2) = 2^(1/3)((2)^2 - 9) = -2√2

So, the values of the function at the critical points and endpoints are:

f(-4) = -8√2

f(-3) = 0

f(2) = -2√2

The absolute maximum value is the largest value among these three values, which is 0. The absolute minimum value is the smallest value among these three values, which is -8√2.

56

Answers

Answer:

the value of x in the equation is -52.

Step-by-step explanation:

To find the value of x in the equation:

(1/3)x - (2/3) = -18

We can start by isolating the variable x.

Add (2/3) to both sides of the equation:

(1/3)x = -18 + (2/3)

Now, we need to find a common denominator for the fractions on the right side:

(1/3)x = (-18 * 3 + 2)/3

Simplifying the expression on the right side:

(1/3)x = (-54 + 2)/3

(1/3)x = -52/3

To eliminate the fraction, we can multiply both sides of the equation by 3:

3 * (1/3)x = 3 * (-52/3)

This simplifies to:

x = -52

Derivatives Of Higher Order Can Be Very Time-Consuming – Especially For Functions Like F(X) = X5 · E−4x. Using The Structure Of

Answers

Derivatives of higher order can be very time-consuming, especially for functions like f(x) = x5 · e−4x. Using the structure of f(x), obtain an expression for the nth derivative of f(x), and evaluate it at x = 0.

Let's find the derivative of the given function f(x) = x5·e^-4x.

Using the product rule we getf(x) = x5·e^-4x= x^5 (d/dx)[e^-4x] + e^-4x (d/dx)[x^5]f'(x) = x^5 (-4e^-4x) + e^-4x (5x^4)f'(x) = -4x^5e^-4x + 5x^4e^-4x

In order to calculate the second derivative, we will need to differentiate f'(x) Using the product rule, we can obtainf'(x) = -4x^5e^-4x + 5x^4e^-4x; f''(x) = (-4e^-4x)·(5x^4) + (20x^3)·e^-4xf''(x) = -20x^4e^-4x + 20x^3e^-4x; f''(x) = 20x^3(-e^-4x + x·e^-4x)

The third derivative of f(x) is calculated by differentiating f''(x), which givesf''(x) = -20x^4e^-4x + 20x^3e^-4x; f'''(x) = (-20e^-4x)·(20x^3) + (60x^2)·e^-4xf'''(x) = -400x^3e^-4x + 60x^2e^-4x; f'''(x) = 20x^2(-20e^-4x + 3x·e^-4x)

Hence the nth derivative of f(x) is given byfn(x) = 20x^(n-1)(a_n·e^-4x + b_n·x·e^-4x) where a_n and b_n are constants to be determined and fn(0) can be evaluated as follows:f(0) = 0, f'(0) = 0, f''(0) = 0, f'''(0) = 0, f''''(0) = 60

We can use the above information to solve for a_n and b_n:a_1 = -4, b_1 = 5a_2 = (-4)·(-20) + 5·20 = 120, b_2 = (-4)·20 + 5·(5) = -60a_3 = (-20)·120 + 5·(-60) = -2400, b_3 = (-20)(-60) + 5(20) = 1000

So the nth derivative off(x) is given by fn(x) = 20x^(n-1) (-4n·e^-4x + bn·x·e^-4x) wherebn = (-4)^n n! + 5(-4)^{n-1} (n-1)!

a) The table will be complete:

y1 y2 y3 Sum Distribution (%)

x1 = 0 30 10 20 50%

x2 = 2 10 10 40 50%

Sum 40 20 60 100%

b) For characteristic X, the mode is x1 = 0, with a frequency of 40.

For characteristic Y, the modes are y1 = -2 and y3 = 3, each with a frequency of 30.

For characteristic X, since there are only two values (0 and 2) and each has a frequency of 20, there is no unique middle value.

For characteristic Y, the median is 0 since it is the middle value of the sorted values (-2, 0, 3).

c)  the conditional distribution, we divide each frequency by the sum: h(X | y3=3) = frequency / sum = (20 / 60, 40 / 60) = (1/3, 2/3).

To calculate the missing information in the table and answer the questions, we will go through each step one by one.

a) Calculate all the missing information in the table.

The missing values in the table can be calculated as follows:

For the x2, y1 cell:

Since the sum of each row must be equal to the row sum distribution, we can calculate the missing value as:

x2, y1 = row sum distribution (x2) - x2, y2 = 20 - 10 = 10

For the x1, y3 cell:

Similarly, we can calculate the missing value as:

x1, y3 = row sum distribution (x1) - x1, y1 = 50 - 30 = 20

For the x2, y3 cell:

Since the sum of each column must be equal to the column sum distribution, we can calculate the missing value as:

x2, y3 = column sum distribution (y3) - x1, y3 = 60 - 20 = 40

For the row sum distribution of x1:

We can calculate it by adding up all the frequencies in row x1:

row sum distribution (x1) = x1, y1 + x1, y2 + x1, y3 = 30 + 10 + 20 = 60

For the column sum distribution of y2:

We can calculate it by adding up all the frequencies in column y2:

column sum distribution (y2) = x1, y2 + x2, y2 = 10 + 10 = 20

Now the table will be complete:

y1 y2 y3 Sum Distribution (%)

x1 = 0 30 10 20 50%

x2 = 2 10 10 40 50%

Sum 40 20 60 100%

b) Determine the mode and the median of both characteristics.

Mode:

The mode is the value(s) that appear most frequently in each characteristic.

For characteristic X, the mode is x1 = 0, with a frequency of 40.

For characteristic Y, the modes are y1 = -2 and y3 = 3, each with a frequency of 30.

Median:

The median is the middle value of a sorted dataset.

For characteristic X, since there are only two values (0 and 2) and each has a frequency of 20, there is no unique middle value.

For characteristic Y, the median is 0 since it is the middle value of the sorted values (-2, 0, 3).

c) Give the conditional distribution of the variable X if Y realizes the value 3, i.e., h(X | y3=3).

The conditional distribution of X given Y = 3 can be calculated by dividing the frequency in each cell where Y = 3 by the total frequency when Y = 3.

y3

x1 = 0 20

x2 = 2 40

Sum 60

To calculate the conditional distribution, we divide each frequency by the sum: h(X | y3=3) = frequency / sum = (20 / 60, 40 / 60) = (1/3, 2/3).

Apply the altemating series test to the serios \[ \sum_{n=2}^{\infty}(-1)^{n} \frac{\ln (6 n)}{n} \text {, } \] First, let \( b_{n}= \) बिखeक? ?

Answers

Given a series, \[\sum\limits_{n = 2}^\infty  {{{( - 1)}^n}\frac{{\ln (6n)}}{n}} \]We have to apply the alternating series test to the given series.

Let's first define the \(b_n\) for the above series. Here, each term of the series, \(\frac{\ln(6n)}{n}\), is positive for all values of \(n\). So, here we have to consider the absolute value of the series \[\sum\limits_{n = 2}^\infty  {\frac{{\ln (6n)}}{n}} \] and then apply the alternating series test.Let \[b_n = \frac{{\ln (6n)}}{n}\]Now, we have to check the conditions of the Alternating Series Test.The conditions are,The sequence \(b_n\) is monotonic decreasing. That is, \[{b_n} \ge {b_{n + 1}}\]The \({\lim_{n \to \infty} } b_n=0\)Now, check the first condition:The sequence \[b_n = \frac{{\ln (6n)}}{n}\]is decreasing as the derivative \[({b_n})' = \frac{{1 - \ln (6n)}}{{{n^2}}}\] is negative for all values of \(n\). Hence, the first condition is satisfied.Now, let's check the second condition. So, \[\mathop {\lim }\limits_{n \to \infty } {b_n} = \mathop {\lim }\limits_{n \to \infty } \frac{{\ln (6n)}}{n} = \mathop {\lim }\limits_{n \to \infty } \frac{{\ln 6}}{{n\ln {n^{ - 1}}}}\]Let \[\mathop {\lim }\limits_{n \to \infty } \frac{1}{{\ln {n^{ - 1}}}} = \mathop {\lim }\limits_{x \to 0} \frac{1}{x} = + \infty \]So, \[\mathop {\lim }\limits_{n \to \infty } {b_n} = \mathop {\lim }\limits_{n \to \infty } \frac{{\ln 6}}{{n\ln {n^{ - 1}}}} = \mathop {\lim }\limits_{n \to \infty } \frac{{\ln 6}}{{\ln {n^{ - 1}}}} = \mathop {\lim }\limits_{x \to 0} \frac{{\ln 6}}{x} = +n  \infty \]

Hence, the second condition is not satisfied as the limit is not zero for this series.So, we cannot use the Alternating Series Test for the given series.
