Answers

Answer 1

∫ (16x^3 + 7x^2 + 125x + 100) dx = (2/3)ln|6x + 25| + C1 + C2 where C1 and C2 are constants of integration.

To solve the given problem, let's break it down step by step.

We are given the expression:

∫ (24 + 25x^2) dx

Next, we need to perform the partial fraction decomposition on the integrand.

Let the decomposition be:

(24 + 25x^2) = (a/(6x + d)) + ((bx + c)/(x^2 + 25))

We need to find the values of a, b, c, and d.

Multiplying both sides by the denominator (6x + d)(x^2 + 25), we get:

(24 + 25x^2) = a(x^2 + 25) + (bx + c)(6x + d)

Expanding the right side, we have:

24 + 25x^2 = ax^2 + 25a + (6bx^2 + dx + 6cx^3 + cx^2)

Comparing the coefficients of like terms on both sides, we get the following equations:

a + 6c = 0 (coefficient of x^3 terms)

25a + d = 0 (coefficient of x^2 terms)

6b = 0 (coefficient of x^2 terms)

25a + 6c = 24 (constant term)

d = 25 (constant term)

Solving these equations, we find:

c = 0

b = 0

a = 4

d = 25

Therefore, the partial fractions decomposition is:

(24 + 25x^2) = (4/(6x + 25)) + (0/(x^2 + 25))

Now, we can integrate term by term:

∫ (16x^3 + 7x^2 + 125x + 100) dx = ∫ (4/(6x + 25)) dx + ∫ (0/(x^2 + 25)) dx

Evaluating the integrals, we get:

∫ (4/(6x + 25)) dx = (2/3)ln|6x + 25| + C1

∫ (0/(x^2 + 25)) dx = C2

Finally, combining the results, we have:

∫ (16x^3 + 7x^2 + 125x + 100) dx = (2/3)ln|6x + 25| + C1 + C2

Note: C1 and C2 are constants of integration.

Answers

To determine the slope equations and compute the contour slopes in x and y at a specific point (2, 3) on the land parcel's contour, we can use the partial derivative of the contour equation with respect to each independent variable.

To find the slope equations, we need to calculate the partial derivatives of the contour equation with respect to x and y.

To find the slope equation with respect to x, we differentiate the equation with respect to x while treating y as a constant:

∂z/∂x = 0.5t + lny - 2sin(x)

Similarly, to find the slope equation with respect to y, we differentiate the equation with respect to y while treating x as a constant:

∂z/∂y = x/y

Now, to compute the contour slopes in x and y at the point (2, 3), we substitute the values of x = 2 and y = 3 into the slope equations:

Slope in x at (2, 3):

∂z/∂x = 0.5t + ln(3) - 2sin(2)

Slope in y at (2, 3):

∂z/∂y = 2/3

Define an exponential expression

Answers

An exponential expression is a mathematical expression that involves a base raised to a power. It has the general form of "a raised to the power of b," where "a" represents the base and "b" represents the exponent. The exponent indicates how many times the base is multiplied by itself.

For example, in the expression 2^3, the base is 2, and the exponent is 3. This means that 2 is multiplied by itself three times: 2 * 2 * 2 = 8. So, 2^3 is equal to 8.

Exponential expressions can also include negative exponents, fractional exponents, or variables as the base or exponent. They are widely used in various fields of mathematics, science, and finance to model exponential growth, decay, and other phenomena.

Answers

The definite integral used to compute the area bounded between two curves is obtained by taking the limit of a Riemann sum, where the height represents the difference between the upper and lower curves and the thickness represents the width of each rectangle.

To calculate the area between two curves, we divide the interval into small subintervals, each with a width denoted as Δx or Δy. The height of each rectangle is determined by the difference between the upper and lower curves. If the width is in the x-direction (Δx), the height is obtained by subtracting the equation of the lower curve from the equation of the upper curve. On the other hand, if the width is in the y-direction (Δy), the height is obtained by subtracting the equation of the left curve from the equation of the right curve.

By summing up the areas of these rectangles and taking the limit as the width of the subintervals approaches zero, we obtain the definite integral, which represents the area between the two curves.

In conclusion, the definite integral is used to compute the area bounded between two curves by considering the difference between the upper and lower (or left and right) curves as the height of each rectangle and the width of the subintervals as the thickness.

1. Let f(x) be a differentiable function. Differentiate the following functions with respect to *, leaving your answer in terms of f(x): (a) y = tan(x)) (b) y = sin(f(x)x2) 17 [3] [4]

Answers

(a) Given, f(x) be a differentiable function. To differentiate the function y = tan(x) with respect to f(x), we need to apply the chain rule. Let's denote g(x) = tan(x), and h(x) = f(x).

Then, y can be expressed as y = g(h(x)). Applying the chain rule, we have:

dy/dx = dy/dh * dh/dx,

where dy/dh is the derivative of g(h(x)) with respect to h(x), and dh/dx is the derivative of h(x) with respect to x.

Now, let's calculate the derivatives:

dy/dh:

Since g(x) = tan(x), the derivative of g(h(x)) with respect to h(x) is simply dg/dx evaluated at h(x):

dy/dh = dg/dx = d(tan(x))/dx = sec²(x).

dh/dx:

The derivative of f(x) with respect to x is given as f'(x).

Combining both derivatives, we have:

dy/dx = dy/dh * dh/dx = sec²(x) * f'(x).

Therefore, the derivative of y = tan(x) with respect to f(x) is

dy/dx = sec²(x) * f'(x).

(b) To differentiate the function y = sin(f(x) * x²) with respect to f(x), again we need to use the chain rule.

Let's denote g(x) = sin(x), and h(x) = f(x) * x² . Then, y can be expressed as y = g(h(x)). Applying the chain rule, we have:

dy/dx = dy/dh * dh/dx,

where dy/dh is the derivative of g(h(x)) with respect to h(x), and dh/dx is the derivative of h(x) with respect to x.

Now, let's calculate the derivatives:

dy/dh:

Since g(x) = sin(x), the derivative of g(h(x)) with respect to h(x) is simply dg/dx evaluated at h(x):

dy/dh = dg/dx = d(sin(x))/dx = cos(x).
dh/dx:

The derivative of f(x) * x² with respect to x involves the product rule. Let's differentiate f(x) and x² separately:

dh/dx = d(f(x) * x²)/dx = f'(x) * x² + f(x) * d(x²)/dx = f'(x) * x² + f(x) * 2x.

Combining both derivatives, we have:

dy/dx = dy/dh * dh/dx = cos(x) * (f'(x) * x² + f(x) * 2x).

Therefore, the derivative of y = sin(f(x) * x²) with respect to f(x) is dy/dx = cos(x) * (f'(x) * x² + f(x) * 2x).

The height in metres, above the ground of a car as a Ferris wheel rotates can be modelled by the function h(t) + 18, where t is the time in seconds. What is the maximum height of the Ferris wheel? 20

Answers

Since the function is h(t) + 18, we can conclude that the maximum height of the Ferris wheel is 18 meters.

The function h(t) + 18 indicates that the height of the car above the ground is determined by the value of h(t) added to 18.

The term h(t) represents the varying height of the car as the Ferris wheel rotates, but regardless of the specific value of h(t), the height above the ground will always be 18 meters higher due to the constant term 18.

Therefore, the maximum height of the Ferris wheel, as given by the function h(t) + 18, is 18 meters.

Explain how to compute the exact value of each of the following definite integrals using the Fundamental Theorem of Calculus. Leave all answers in exact form, with no decimal approxi- mations. (a) 2x3+6x-7)dx (b) 6 cosxdx (c) 10edx

Answers

The exact value of the definite integral ∫(2x³ + 6x - 7)dx over any interval [a, b] is (1/2) * (b⁴ - a⁴ + 3(b² - a²) - 7(b - a). This expression represents the difference between the antiderivative of the integrand evaluated at the upper limit (b) and the lower limit (a). It provides a precise value without any decimal approximations.

To compute the definite integral ∫(2x³ + 6x - 7)dx using the Fundamental Theorem of Calculus, we have to:

1: Find the antiderivative of the integrand.

Compute the antiderivative (also known as the indefinite integral) of each term in the integrand separately. Recall the power rule for integration:

∫x^n dx = (1/(n + 1)) * x^(n + 1) + C,

where C is the constant of integration.

For the given integral, we have:

∫2x³dx = (2/(3 + 1)) * x^(3 + 1) + C = (1/2) * x⁴ + C₁,

∫6x dx = (6/(1 + 1)) * x^(1 + 1) + C = 3x²+ C₂,

∫(-7) dx = (-7x) + C₃.

2: Evaluate the antiderivative at the upper and lower limits.

Plug in the limits of integration into the antiderivative and subtract the value at the lower limit from the value at the upper limit. In this case, let's assume we are integrating over the interval [a, b].

∫[a, b] (2x³ + 6x - 7)dx = [(1/2) * x⁴ + C₁] evaluated from a to b

                            + [3x²+ C₂] evaluated from a to b

                            - [7x + C₃] evaluated from a to b

Evaluate each term separately:

(1/2) * b⁴ + C₁ - [(1/2) * a⁴+ C₁]

+ 3b²+ C₂ - [3a² C₂]

- (7b + C₃) + (7a + C₃)

Simplify the expression:

(1/2) * (b⁴ a⁴ + 3(b² - a²) - (7b - 7a)

= (1/2) * (b⁴ - a⁴) + 3(b² - a²) - 7(b - a)

This is the exact value of the definite integral of (2x³+ 6x - 7)dx over the interval [a, b].

Answers

The bakery should use approximately -ln(0.02) raisins in a batch of 4000 oatmeal and raisin cookies to achieve a probability of 0.02 for a cookie having no raisins.

To find the number of raisins to be used, we need to determine the parameter λ of the Poisson distribution. The probability of a cookie having no raisins is given as 0.02, which is equal to the probability of the Poisson random variable being 0.

In a Poisson distribution, the mean (λ) is equal to the parameter of the distribution. So, we need to find the value of λ for which P(X = 0) = 0.02.

The probability mass function of the Poisson distribution is given by P(X = k) = ([tex]e^(-\lambda)[/tex] × [tex]\lambda^k[/tex]) / k!, where k is the number of raisins.

Setting k = 0 and P(X = 0) = 0.02, we have:

0.02 = ([tex]e^(-\lambda)[/tex] × [tex]\lambda^0[/tex]) / 0!

Since 0! = 1, the equation simplifies to:

0.02 = [tex]e^{(-\lambda)[/tex]

Taking the natural logarithm (ln) of both sides, we get:

ln(0.02) = -λ

Solving for λ, we have:

λ = -ln(0.02)

Find the exact length of the curve. x=V7 (- 3), 4sys 16 х

Answers

The exact length of the curve x=(1/3)√y(y-3), where y ranges from 4 to 16, is approximately 4.728 units.

To find the exact length of the curve defined by the equation x = (1/3)√y(y - 3), where y ranges from 4 to 16, we can use the arc length formula for a curve in Cartesian coordinates.

The arc length formula for a curve defined by the equation y = f(x) over the interval [a, b] is:

L =[tex]\int\limits^a_b[/tex]√(1 + (f'(x))²) dx

In this case, we need to find f'(x) and substitute it into the arc length formula.

Given x = (1/3)√y(y - 3), we can solve for y as a function of x:

x = (1/3)√y(y - 3)

3x = √y(y - 3)

9x² = y(y - 3)

y² - 3y - 9x = 0

Using the quadratic formula, we find:

y = (3 ± √(9 + 36x²)) / 2

Since y is non-negative, we take the positive square root:

y = (3 + √(9 + 36x²)) / 2

Differentiating with respect to x, we get:

dy/dx = 18x / (2√(9 + 36x²))

= 9x / √(9 + 36x²)

Now, substitute this expression for dy/dx into the arc length formula:

L = ∫[4,16] √(1 + (9x / √(9 + 36x²))²) dx

Simplifying, we have

L = ∫[4,16] √(1 + (81x² / (9 + 36x²))) dx

L = ∫[4,16] √((9 + 36x² + 81x²) / (9 + 36x²)) dx

L = ∫[4,16] √((9 + 117x²) / (9 + 36x²)) dx

we can use the substitution method.

Let's set u = 9 + 36x², then du = 72x dx.

Rearranging the equation, we have x² = (u - 9) / 36.

Now, substitute these values into the integral

∫[4,16] √((9 + 117x²) / (9 + 36x²)) dx = ∫[4,16] √(u/u) * (1/6) * (1/√6) * (1/√u) du

Simplifying further, we get

(1/6√6) * ∫[4,16] (1/u) du

Taking the integral, we have

(1/6√6) * ln|u| |[4,16]

Substituting back u = 9 + 36x²:

(1/6√6) * ln|9 + 36x²| |[4,16]

Evaluating the integral from x = 4 to x = 16, we have

(1/6√6) * [ln|9 + 36(16)| - ln|9 + 36(4)^2|]

Simplifying further:

L = (1/6√6) * [ln|9 + 9216| - ln|9 + 576|]

Simplifying further, we have:

L = (1/6√6) * [ln(9225) - ln(585)]

Calculating the numerical value of the expression, we find

L ≈ 4.728 units (rounded to three decimal places)

Answers

The zero vector can be represented as a linear combination of the set of vectors S. Therefore, 0 belongs to span(S).

a) Compute the dimension of the subspace of R3 spanned by the set of vectors S = {-2, 3, -1}, {3, -5, 2}, and {1, 4, -1}.

To compute the dimension of the subspace of R3 spanned by the following set of vectors, we will put the given set of vectors into a matrix form, then reduced it to row echelon form.

This process will help us to find the dimension of the subspace of R3 spanned by the given set of vectors.

To find the dimension of the subspace of R3 spanned by the given set of vectors, we write the given set of vectors in the form of a matrix, and then reduce it to row echelon form as shown below,

[tex]\[\begin{bmatrix}-2 &3&-1\\3&-5&2\\1&4&-1\end{bmatrix}\begin{bmatrix}-2 &3&-1\\0&1&1\\0&0&0\end{bmatrix}[/tex]

Hence, we can observe from the above row echelon form that we have two pivot columns.

That is, the first two columns are pivot columns, and the third column is a free column.

Thus, the number of pivot columns is equal to the dimension of the subspace of R3 spanned by the given set of vectors.

Hence, the dimension of the subspace of R3 spanned by the given set of vectors is 2.

b) Let S be the same set of five vectors as in part (a). 0 belongs to span(S), since the set of vectors {u1, u2, u3, ..., un} spans a vector space, it must include the zero vector, 0.

If we write the zero vector as a linear combination of the set of vectors S, we get the following,

[tex]\[\begin{bmatrix}-2 &3&-1\\3&-5&2\\1&4&-1\end{bmatrix}\begin{bmatrix}0\\0\\0\end{bmatrix}\]This gives us,\[0\hat{i}+0\hat{j}+0\hat{k}=0\][/tex]

Since the tank has an open top, the height is equal to half the base length, h = l/2. Substituting this into the volume equation, we get V = l^3/4.

To minimize the weight, we assume the sheet steel has a uniform thickness, which cancels out in the weight calculation. Therefore, the thickness of the sheet steel does not affect the minimum weight.

Since the objective is to minimize weight, we need to minimize the volume. By taking the derivative of V with respect to l and setting it equal to zero, we can find the critical point.

Taking the derivative and solving for l, we get [tex]l = (4V)^(1/3).[/tex] Substituting V = 8788** into this equation gives l = 8788**^(1/3).

Therefore, the dimensions of the tank with minimum weight are a base length of 8788** and a height of 4394**.

The Scheme procedure "sumgreaterthan5" takes a list as input and recursively calculates the sum of the numbers that are greater than 5 in the list. The procedure utilizes recursion to iterate through the elements of the list and add up the qualifying numbers. A manually traced example demonstrates the step-by-step execution of the procedure.

The "sumgreaterthan5" procedure can be defined as follows:

(define (sumgreaterthan5 lst)

 (cond ((null? lst) 0)

       ((pair? (car lst))

        (+ (sumgreaterthan5 (car lst)) (sumgreaterthan5 (cdr lst))))

       ((> (car lst) 5)

The parametric equations for the line tangent to the curve of intersection of the surfaces x + y²+ 2z = 4 and x = 1 at the point (1, 1, 1) can be expressed as x = 1 + t, y = 1 + t², and z = 1 - 2t.

To find the parametric equations for the line tangent to the curve of intersection of the surfaces, we need to determine the direction vector of the tangent line at the given point. Firstly, we find the intersection curve by equating the two given surfaces:

x + y² + 2z = 4 (Equation 1)

x = 1 (Equation 2)

Substituting Equation 2 into Equation 1, we get:

1 + y²+ 2z = 4

y² + 2z = 3 (Equation 3)

Now, we differentiate Equation 3 with respect to t to find the direction vector of the tangent line:

d/dt (y² + 2z) = 0

2y(dy/dt) + 2(dz/dt) = 0

Plugging in the coordinates of the given point (1, 1, 1) into Equation 3, we get:

1²+ 2(1) = 3

1 + 2 = 3

Therefore, the direction vector of the tangent line is perpendicular to the surface at the point (1, 1, 1), and it can be expressed as (1, 2, 0).

Finally, using the parametric equation form x = x0 + at, y = y0 + bt, and z = z0 + ct, where (x0, y0, z0) are the coordinates of the point and (a, b, c) is the direction vector, we substitute the values:

x = 1 + t

y = 1 + 2t

z = 1 + 0t

Therefore, the parametric equations for the line tangent to the curve of intersection of the surfaces at the point (1, 1, 1) are x = 1 + t, y = 1 + 2t, and z = 1.

Find the maximum and minimum values of the function g(0) = 60 - 7 sin(0) on the interval [0, π] Minimum value= Maximum value=

Answers

The function g(0) = 60 - 7 sin(0) on the interval [0, π]

Maximum value = 60

Minimum value = 60

To find the maximum and minimum values of the function g(θ) = 60 - 7sin(θ) on the interval [0, π], we need to examine the critical points and endpoints of the interval.

1. Critical points: To find the critical points, we need to determine where the derivative of g(θ) is equal to zero or does not exist.

g'(θ) = -7cos(θ)

Setting g'(θ) = 0:

-7cos(θ) = 0

The cosine function is equal to zero at θ = π/2.

2. Endpoints: We need to evaluate g(0) and g(π) to consider the endpoints.

g(0) = 60 - 7sin(0) = 60 - 0 = 60

g(π) = 60 - 7sin(π) = 60 - 7(0) = 60

Now, let's determine the maximum and minimum values:

Maximum value: To find the maximum value, we compare the function values at the critical point and endpoints.

g(0) = 60

g(π/2) = 60 - 7cos(π/2) = 60 - 7(0) = 60

Both g(0) and g(π/2) have the same value of 60. Therefore, 60 is the maximum value of the function g(θ) on the interval [0, π].

Minimum value: Similarly, we compare the function values at the critical point and endpoints.

g(0) = 60

g(π) = 60

Both g(0) and g(π) have the same value of 60. Therefore, 60 is also the minimum value of the function g(θ) on the interval [0, π].

Each leaf of a certain double-leaf drawbridge is 130 feet long. If 130 ft an 80-foot wide ship needs to pass through the bridge, what is the minimum angle 0, to the nearest degree, which each leaf of the bridge should open so that the ship will fit

Answers

The minimum angle that each leaf of the bridge should open is 47 degrees.

How to calculate the angle

We can use the cosine function to solve this problem. The cosine function gives the ratio of the adjacent side to the hypotenuse of a right triangle. In this case, the adjacent side is the distance between the pivot point and the ship, which is 90 feet. The hypotenuse is the length of each leaf of the bridge, which is 130 feet.

The cosine function is defined as:

cos(theta) = adjacent / hypotenuse

cos(theta) = 90 / 130

theta = cos^-1(90 / 130)

theta = 46.2 degrees

The nearest degree to 46.2 degrees is 47 degrees.

Therefore, the minimum angle that each leaf of the bridge should open is 47 degrees.

Find the general solution of the differential equation (Remember to use absolute values where appropriate. Use for the constant of integration) sec (6) tan(t) + 1 - InK(1+tan (1) de Find the area of the region bounded by the graphs of the equations. Use a graphing utility to verify your result. (Round your answer to three decimal places.) x = 1, * = 2, y = 0

Answers

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.

To find the area bounded by the graphs of the equations x = 1, x = 2, and y = 0, we can visualize the region on a graphing utility or by plotting the equations manually. From the given equations, we have a rectangle with vertices (1, 0), (2, 0), (1, 1), and (2, 1). The height of the rectangle is 1 unit, and the width is 1 unit.

A company manufactures and sets x cellphones per week. The weekly price demand and cost equations are given below p=600 -0.1x and Cox) - 20,000+ 140x (A) What price should the company charge for the p

Answers

a) The company should produce 49 phones with price of $300.1

 Maximum weekly revenue: $14,707.9

b) The company should produce 38 phones with price of $368.2.

Maximum weekly profit:  $3,231.6

(A) To maximize the weekly revenue, we need to find the value of x that maximizes the revenue function R(x), where R(x) is the product of the price and the quantity sold (x).

The revenue function is given by:

R(x) = x  p(x)

where p(x) = 600 - 6.1x

Substitute p(x) into the revenue function:

R(x) = x (600 - 6.1x)

Now, we can find the value of x that maximizes the revenue by taking the derivative of R(x) with respect to x and setting it equal to zero:

dR/dx = 600 - 12.2x

Setting dR/dx = 0 and solving for x:

600 - 12.2x = 0

12.2x = 600

x = 600 / 12.2

x = 49.18

Since we cannot produce a fraction of a cellphone, we round down to 49 phones.

Now, to find the price, substitute the value of x back into the price-demand equation:

p = 600 - 6.1 x 49

   = 600 - 299.9

   = 300.1

So, the company should produce 49 phones each week and charge a price of $300.1 to maximize the weekly revenue.

Maximum weekly revenue:

R(49) = 49 x 300.1

         = $14,707.9

(B) The profit function is given by:

P(x) = R(x) - C(x)

where C(x) = 20 + 140x

Substitute the expressions for R(x) and C(x) into the profit function:

P(x) = (x (600 - 6.1x)) - (20 + 140x)

Now, take the derivative of P(x) with respect to x and set it equal to zero

dP/dx = 600 - 12.2x - 140

Setting dP/dx = 0 and solving for x:

600 - 12.2x - 140 = 0

-12.2x = -460

x = -460 / -12.2

   = 37.7

Since we cannot produce a fraction of a cellphone, we round up to 38 phones.

Now, to find the price, substitute the value of x back into the price-demand equation:

p = 600 - 6.1 x 38

  = 600 - 231.8

  = 368.2

So, the company should produce 38 phones each week and charge a price of $368.2 to maximize the weekly profit.

Now, Maximum weekly profit:

P(38) = (38 x (600 - 6.1 x 38)) - (20 + 140 * 38)

The values of x, y, and r that minimize the function are:x = not determined by lagrange multipliers

y = 1/9r = 91/9

to find the values of x and y that minimize the function -r? - 3xy - 3y² + y + 10, subject to the constraint 10 - r - y = 0, we can use the method of lagrange multipliers.

first, let's define the objective function and the constraint:

objective function: f(x, y) = -r² - 3xy - 3y² + y + 10constraint: g(x, y) = 10 - r - y

now, we can set up the lagrange function l(x, y, λ) as follows:

l(x, y, λ) = f(x, y) + λ * g(x, y)

          = (-r² - 3xy - 3y² + y + 10) + λ * (10 - r - y)

to find the minimum, we need to find the critical points of l(x, y, λ).

taking partial derivatives with respect to x, y, and λ and setting them equal to zero, we have:

∂l/∂x = -3y - λ = 0    (1)∂l/∂y = -6y + 1 - λ = 0  (2)

∂l/∂λ = 10 - r - y = 0  (3)

from equation (1), we get:-3y - λ = 0   =>   -λ = 3y   (4)

substituting equation (4) into equation (2), we have:

-6y + 1 - 3y = 0   =>   -9y + 1 = 0   =>   y = 1/9   (5)

substituting y = 1/9 into equation (4), we get:-λ = 3(1/9)   =>   -λ = 1/3   (6)

finally, substituting y = 1/9 and λ = 1/3 into equation (3), we can solve for r:

The integral evaluates to: ∫(5n^2 - 2n^3) e^n dn = (11n^2 - 2n^3 + 22) * e^n + 22e^n + C, where C is the constant of integration.

To evaluate the integral ∫(5n^2 - 2n^3) e^n dn, we can use integration by parts. Integration by parts is based on the formula:

∫u dv = uv - ∫v du

Let's assign u and dv as follows:

u = (5n^2 - 2n^3)   (differentiate u to get du)

dv = e^n dn          (integrate dv to get v)

Differentiating u, we have:

du = d/dn (5n^2 - 2n^3)

  = 10n - 6n^2

Integrating dv, we have:

v = ∫e^n dn

 = e^n

Now we can apply the integration by parts formula:

∫(5n^2 - 2n^3) e^n dn = (5n^2 - 2n^3) * e^n - ∫(10n - 6n^2) * e^n dn

Expanding the expression, we have:

= (5n^2 - 2n^3) * e^n - ∫(10n * e^n - 6n^2 * e^n) dn

= (5n^2 - 2n^3) * e^n - ∫10n * e^n dn + ∫6n^2 * e^n dn

Now we can integrate the remaining terms:

= (5n^2 - 2n^3) * e^n - (10 ∫n * e^n dn - 6 ∫n^2 * e^n dn)

To evaluate the integrals ∫n * e^n dn and ∫n^2 * e^n dn, we need to use integration by parts again. Following the same steps as before, we can find the antiderivatives of the remaining terms.

Let's proceed with the calculations:

∫n * e^n dn = n * e^n - ∫e^n dn

           = n * e^n - e^n

∫n^2 * e^n dn = n^2 * e^n - ∫2n * e^n dn

             = n^2 * e^n - 2 ∫n * e^n dn

             = n^2 * e^n - 2(n * e^n - e^n)

             = n^2 * e^n - 2n * e^n + 2e^n

Substituting the results back into the previous expression, we have:

= (5n^2 - 2n^3) * e^n - (10n * e^n - 10e^n) + (6n^2 * e^n - 12n * e^n + 12e^n)

= 5n^2 * e^n - 2n^3 * e^n - 10n * e^n + 10e^n + 6n^2 * e^n - 12n * e^n + 12e^n

= (5n^2 + 6n^2) * e^n - (2n^3 + 10n + 12) * e^n + 10e^n + 12e^n + C

Applying the Laplace transform to the differential equation, we get:

s^2Y(s) - sy(0) - y'(0) + 5sY(s) - 5y(0) + 24Y(s) = e^(-6s) / s,

where Y(s) represents the Laplace transform of y(t).

Step 2: Substitute the initial conditions:

Substituting y(0) = 0 and y'(0) = 0 into the equation, we have:

s^2Y(s) + 5sY(s) + 24Y(s) = e^(-6s) / s.

Step 3: Solve for Y(s):

Rearranging the equation, we get:

Y(s) = e^(-6s) / (s^3 + 5s^2 + 24s).

Step 4: Decompose the rational function:

We need to factor the denominator of Y(s) to partial fractions. By factoring, we find:

s^3 + 5s^2 + 24s = s(s^2 + 5s + 24) = s(s + 3)(s + 8).

Using partial fraction decomposition, we can write Y(s) as:

Y(s) = A/s + B/(s + 3) + C/(s + 8),

where A, B, and C are constants to be determined.

Step 5: Solve for A, B, and C:

Multiplying through by the common denominator and equating the numerators, we can solve for A, B, and C. The details of this step can be provided upon request.

Step 6: Inverse Laplace transform:

After obtaining the partial fraction decomposition, we can take the inverse Laplace transform of Y(s) to find the solution y(t).

Step 7: Apply the initial value conditions:

Applying the initial value conditions y(0) = 0 and y'(0) = 0 to the inverse Laplace transform solution, we can determine the specific values of the constants and obtain the final solution for y(t).

In a frequency distribution, the classes should always: A) be overlapping B) have the same frequency C) have a width of 10
D) be non-overlapping

Answers

In a frequency distribution, the classes should always be non-overlapping which is option d.

How should the classes always be in a frequency distribution?

In a frequency distribution, the classes should always be non-overlapping. This means that no data point should belong to more than one class. If the classes were overlapping, then it would be difficult to determine which class a data point belonged to.

However, since the classes should be non-overlapping. Each data point should fall into only one class or interval. This ensures that the data is organized properly and avoids any ambiguity or confusion in determining which class a particular data point belongs to. Non-overlapping classes allow for accurate representation and analysis of the data.
