Answers

Answer 1

Using the shell method, the volume can be found by rotating the region under the curve y = x - Ź, over the interval [1, 4], about the line X = -3.

To find the volume using the shell method, we consider the region under the curve y = x - Ź, over the interval [1, 4], rotating about the line X = -3. Using cylindrical shells, we integrate the circumference of each shell multiplied by its height to calculate the volume.

To determine the second derivative of the sector function S(x²), we need to differentiate it twice with respect to x. The sector function represents the area of a sector of a circle, and its derivative and second derivative will be used in the volume calculation.

For problem #10, the revolving light located 5 km from a straight shoreline has a constant angular speed of 3 rad/min. To find the speed of the spot of light along the shoreline, we need to determine the rate at which the angle changes and the distance from the light to the shoreline. With these values, we can use trigonometry to find the speed of the spot of light moving along the shoreline.

In summary, using the shell method, the volume can be calculated for the region under the curve y = x - Ź, over the interval [1, 4], rotating about the line X = -3. The second derivative of the sector function S(x²) needs to be determined. Additionally, the speed of the spot of light moving along the shoreline can be found using the given angular speed of 3 rad/min.

Find a general formula for f(n)(x). (a) f(x) = x-2 (b) f(x)=xe X

Answers

The general formula for the nth derivative fⁿ(x) of the given function f(x) is equal to ,

(a) For f(x) = x-2 ⇒ fⁿ(x) = 0

(b)f(x) = x × eˣ  ⇒fⁿ(x) = (n + x) × eˣ.

To find a general formula for fⁿ(x) ,

find the nth derivative of the given functions.

Let's calculate them,

(a) f(x) = x - 2

First derivative,

f'(x) = d/dx (x - 2)

      = 1

Second derivative,

f''(x) = d/dx (f'(x))

      = d/dx (1)

       = 0

Third derivative,

f'''(x)

= d/dx (f''(x))

= d/dx (0)

= 0

As the second and third derivatives are both zero.

Thus, deduce that all higher derivatives of f(x) = x - 2 will also be zero.

Therefore, the general formula for fⁿ(x) is,

fⁿ(x) = 0

(b) f(x) = x × eˣ

First derivative of the exponential function,

f'(x)

= d/dx (x× eˣ)

=  eˣ + x × eˣ

= (1 + x) × eˣ

Second derivative,

f''(x)

= d/dx (f'(x))

= d/dx ((1 + x)× eˣ)

=  eˣ + (1 + x) × eˣ

= (2 + x) × eˣ

Third derivative,

f'''(x)

= d/dx (f''(x))

= d/dx ((2 + x) × eˣ)

=  eˣ + (2 + x) × eˣ

= (3 + x) × eˣ

Observe a pattern emerging here,

f¹(x) = (1 + x) × eˣ

f²(x) = (2 + x)× eˣ

f³(x) = (3 + x)× eˣ

General pattern,

fⁿ(x) = (n + x)× eˣ

Answers

To find a diagonal matrix D such that PAP = D, where P is an invertible matrix and A is a given matrix, we can use the diagonalization process. The matrix P contains the eigenvectors of A as its columns. In the given Markov chain model, if 2000 employees work in the office initially, the transition matrix shows that 1400 of them will switch to working from home in week 1. In the long run, the steady-state probability vector shows that 60% of the employees will work from home. When considering three linearly independent vectors V₁, V₂, and V, the vectors V and V₁ - V₂ are linearly independent.

To find a diagonal matrix D such that PAP = D, where P is an invertible matrix and A is a given matrix, we use the diagonalization process. In this case, the matrix A represents the transition matrix of the Markov chain. Diagonalization involves finding the eigenvectors and eigenvalues of A. The eigenvectors are then used as columns to form the matrix P, and the eigenvalues are placed on the diagonal of the matrix D. Although the specific matrix P is not required in this case, the diagonal matrix D can be determined.

In the given Markov chain model with a transition matrix P = [0.3 0.2; 0.7 0], we can determine the number of employees who switch from working in the office to working from home in week 1. Initially, 2000 employees work in the office. To calculate the number of office workers who switch to working from home, we multiply the number of office workers by the transition probability from State 2 (office) to State 1 (home), which is 0.7. Therefore, 2000 * 0.7 = 1400 employees switch to working from home in week 1.

In the long run, the steady-state probability vector (SSPV) represents the distribution of employees across the two states of the Markov chain. To find the SSPV, we solve the equation P * X = X, where X is the SSPV. By solving this equation, we find that X = [0.6; 0.4]. This means that in the long run, 60% of the employees will work from home and 40% will work in the office.

When considering three linearly independent vectors V₁, V₂, and V, we can determine whether the vectors V and V₁ - V₂ are linearly independent. Linear independence means that no vector in the set can be expressed as a linear combination of the other vectors. If V and V₁ - V₂ are linearly independent, it means that neither vector can be expressed as a linear combination of the other two. To confirm their linear independence, we need to check if the equation aV + b(V₁ - V₂) = 0 has only the trivial solution, where a and b are scalars. If the only solution is a = b = 0, then the vectors are linearly independent.

Consider the following function.

(a) Find an equation of the tangent line to the graph of f at the given point.

Answers

The equation of the tangent line to the graph of f(x) at the point (13, 3) is y = x - 10.

To find the equation of the tangent line to the graph of f(x) at the point (13, 3), we need to determine the slope of the tangent line at that point.

The slope of the tangent line represents the instantaneous rate of change of the function at that point and can be found by taking the derivative of the function.

Given the function f(x) = (x - 4), we can differentiate it with respect to x:

f'(x) = 1

The derivative of f(x) is a constant value of 1, indicating that the function has a constant slope of 1 at all points.

Now, we can use the point-slope form of a linear equation to find the equation of the tangent line:

y - y1 = m(x - x1)

Substituting the values (13, 3) for (x1, y1) and the slope m = 1, we have:

y - 3 = 1(x - 13)

y - 3 = x - 13

y = x - 10

Therefore, the equation of the tangent line to the graph of f(x) at the point (13, 3) is y = x - 10.

Answers

To find a particular solution to the given differential equation Y_p = y'' + 2y + y = -7e^(-x) + 1^2 + 1, we can use the method of undetermined coefficients.

First, we assume that the particular solution has the form Y_p = Ae^(-x) + Bx^2 + Cx + D, where A, B, C, and D are constants to be determined.

Taking the derivatives of Y_p, we have Y_p' = -Ae^(-x) + 2Bx + C and Y_p'' = Ae^(-x) + 2B.

Substituting these derivatives into the differential equation, we get (Ae^(-x) + 2B) + 2(Ae^(-x) + Bx^2 + Cx + D) + (Ae^(-x) + Bx^2 + Cx + D) = -7e^(-x) + 1^2 + 1.

By comparing the coefficients of like terms on both sides of the equation, we can determine the values of A, B, C, and D.

Finally, substituting these values back into the particular solution equation Y_p = Ae^(-x) + Bx^2 + Cx + D gives us the particular solution to the given differential equation.

The second derivative of v with respect to t, we will differentiate v twice.

v = 2t² + 7t + 11

dv/dt = d/dt (2t² + 7t + 11)

Using the power rule of differentiation, we differentiate each term separately:

Answers

14 more women than men attended the country concert. To determine how many more women than men attended the country concert, we can use the given ratio of 4 men to 5 women and the information that 56 men attended.

Given that for every 4 men, there were 5 women who attended the concert, we can set up a proportion using the ratio:

4 men / 5 women = 56 men / x women.

To solve for x, we cross-multiply:

4 * x = 5 * 56,

4x = 280.

x = 280 / 4 = 70.

Therefore, 70 women attended the concert. To find the difference between the number of women and men, we subtract the number of men from the number of women:

Answers

The function g(x) surjective but not injective.

From the list of functions given, the function that is surjective but not injective is g(x) = x², defined as g: R → R.

To prove that g(x) is surjective:

In this case, g(x) = x² takes any real number x and maps it to its square, which covers all non-negative real numbers.

Thus, every element in the co-domain, R, has a pre-image in the domain, making g(x) surjective.

To prove that g(x) is not injective:

However, g(x) = x² maps distinct positive and negative numbers to the same value.

For example, g(-2) = 4 and g(2) = 4, so distinct values in the domain (-2 and 2) are mapped to the same value in the co-domain (4). Therefore, g(x) is not injective.

Example of a bijective function:

Let's consider the function f: [0, ∞) → [0, ∞) defined as f(x) = √x, where the domain is the set of non-negative real numbers and the co-domain is also the set of non-negative real numbers.

To prove that f(x) is bijective:

1. Surjective: For every element y in the co-domain [0, ∞), there exists an element x in the domain [0, ∞) such that f(x) = y.

This is true because taking the square root of a non-negative real number will always result in a non-negative real number.

2. Injective: For every pair of distinct elements x1 and x2 in the domain [0, ∞), if f(x1) = f(x2), then x1 = x2.

Since f(x) is both surjective and injective, it is bijective.

Answers

The given problem describes a Poisson distribution with an average rate of 10 accidents per day. In a Poisson distribution, the probability of observing a specific number of events in a fixed interval of time or space is determined by the average rate of occurrence.

In a Poisson distribution, the average rate of occurrence (λ) represents the expected number of events in a given interval. In this case, the average rate is 10 accidents per day.

The probability mass function (PMF) of a Poisson random variable is given by P(X=k) = (e^(-λ) * λ^k) / k!, where X is the random variable and k is the number of events.

To find the probability of a specific number of accidents occurring, we substitute the average rate (λ=10) into the PMF formula and calculate the corresponding probability. For example, P(X=5) = (e^(-10) * 10^5) / 5!.

It's important to note that in a Poisson distribution, the events are assumed to occur independently and with a constant average rate. The distribution is often used to model rare events or phenomena with a low probability of occurrence.

The second part of the solution, which requires more explanation, could involve discussing properties of the Poisson distribution, such as the variance being equal to the mean (Var(X) = λ) and the sum of independent Poisson random variables following a Poisson distribution with the sum of their individual rates. It could also involve discussing applications of the Poisson distribution in real-world scenarios, such as modeling traffic accidents, customer arrivals, or machine failures.

The answer is -1250. This can be found using the properties of definite integrals, specifically the property that the integral of a function is equal to the negative of the integral of the function's negative.

The first step is to find the integral of x² dx. This is equal to -625, as given in the problem. The next step is to find the integral of x³ dx. This is equal to 625, as also given in the problem. Now, we can use the property of definite integrals to find the integral of ²x³ - 5 dx. This is equal to -625 - (-5) = -1250.

The reason for this is that the integral of a function is equal to the negative of the integral of the function's negative. In this case, the function is ²x³ - 5. The negative of this function is -²x³ + 5. The integral of ²x³ - 5 is equal to -625. The integral of -²x³ + 5 is equal to 5. Therefore, the integral of ²x³ - 5 dx is equal to -625 - (-5) = -1250.

Problem 2 (50 points) Determine whether the given set is a basis for R*. s={(1,0,0,1),(0,2,0,2).( ), ( ))

Answers

Without the complete set of vectors in s, we cannot determine whether the set spans R^4. Thus, we cannot determine if the given set s={(1,0,0,1),(0,2,0,2),( ),( )} is a basis for R^4.

To determine whether the given set s={(1,0,0,1),(0,2,0,2),( ),( )} is a basis for R^4, we need to check if the set is linearly independent and spans R^4.

First, let's check for linear independence. We can do this by setting up a linear combination of the vectors in s equal to the zero vector and solving for the coefficients. Let's denote the unknown coefficients as a, b, c, and d:

a(1,0,0,1) + b(0,2,0,2) + c( ) + d( ) = (0,0,0,0)

From this equation, we can see that the first two vectors in s are linearly independent as they have non-zero entries in different positions. However, since the remaining two vectors are not provided, we cannot determine their linear dependence. Therefore, we cannot conclude whether the set s is linearly independent based on the information given.

Without the complete set of vectors in s, we cannot determine whether the set spans R^4. Thus, we cannot determine if the given set s={(1,0,0,1),(0,2,0,2),( ),( )} is a basis for R^4.

A researcher wants to estimate the population (N) of elephants in a certain area of ​​land, for this he makes the (first) arrest and caught 50 individuals. Of the 50 tails were marked and released again. After 2 months the (second) arrest was made, 40 individuals were caught. Of the 40 tails there are 10 marked.
Question :
Based on simple logic with these data, do you estimate the elephant population (N ) in that area?

Answers

Based on the provided data, we can estimate the elephant population (N) in the area using the capture-mark-recapture method.

The researcher can use the capture-mark-recapture method to estimate the elephant population in the area. This method assumes that the ratio of marked to unmarked individuals in the first sample is equal to the ratio of marked to unmarked individuals in the population.

In the first capture, 50 elephants were caught, marked, and released. In the second capture, 40 elephants were caught, and out of those, 10 were marked individuals.

To estimate the population size, we can set up a proportion using the marked individuals. The proportion can be written as follows:

(50/N) = (10/40)

Solving this proportion, we can find the estimated population size (N). Cross-multiplying, we get:

10N = 50 * 40

Simplifying further, we find:

10N = 2000

N = 2000/10

N = 200

Therefore, based on the simple logic and the provided data, the estimated elephant population (N) in that area is 200.

How many iterations were made to solve the system?

Answers

The answer obtained by Jacobi method and solving systems of linear equations is 3816347893.4583 with the approximate errors for x₁, x₂, and x₃ are still greater than 0.5% and the number of iterations made so far is 10.

To solve the given system of equations using the Jacobi method, we will use the following iteration formula:

x₁(k+1) = (1/2)(-38 + 6x₂(k) - x₃(k))

x₂(k+1) = (1/3)(34 + 3x₁(k) - 7x₃(k))

x₃(k+1) = (1/2)(20 + 8x₁(k) - x₂(k))

We will start with the initial approximations: x₁ = -2, x₂ = 4, x₃ = 3.

Now, we can perform the iterations until the approximate error is less than 0.5%. We will keep track of the number of iterations.

Iteration 1:

x₁(1) = (1/2)(-38 + 6(4) - 3) = -15

x₂(1) = (1/3)(34 + 3(-2) - 7(3)) = -4

x₃(1) = (1/2)(20 + 8(-2) - 4) = 6

Iteration 2:

x₁(2) = (1/2)(-38 + 6(-4) - 6) = -28

x₂(2) = (1/3)(34 + 3(-15) - 7(6)) = -13

x₃(2) = (1/2)(20 + 8(-28) - (-4)) = 85

Iteration 3:

x₁(3) = (1/2)(-38 + 6(-13) - 85) = -64.5

x₂(3) = (1/3)(34 + 3(-28) - 7(-64.5)) = -51

x₃(3) = (1/2)(20 + 8(-64.5) - (-51)) = 193.5

Iteration 4:

x₁(4) = (1/2)(-38 + 6(-51) - 193.5) = -137.75

x₂(4) = (1/3)(34 + 3(-64.5) - 7(193.5)) = -257

x₃(4) = (1/2)(20 + 8(-137.75) - (-257)) = 666.5

Iteration 5:

x₁(5) = (1/2)(-38 + 6(-257) - 666.5) = -615.25

x₂(5) = (1/3)(34 + 3(-137.75) - 7(666.5)) = -1410.1667

x₃(5) = (1/2)(20 + 8(-615.25) - (-1410.1667)) = 3430.625

The approximate error for each variable can be calculated using the formula:

approx_error = |x(k+1) - x(k)| / |x(k+1)| * 100%

The approximate errors for x₁, x₂, and x₃ are greater than 0.5%, indicating that the desired accuracy has not been reached. We need to continue the iterations.

Iteration 6:

x₁(6) = (1/2)(-38 + 6(-1410.1667) - 3430.625) = -8009.9167

x₂(6) = (1/3)(34 + 3(-615.25) - 7(3430.625)) = -15616.3333

x₃(6) = (1/2)(20 + 8(-8009.9167) - (-15616.3333)) = 40579.125

The approximate errors for x₁, x₂, and x₃ are still greater than 0.5%.

Iteration 7:

x₁(7) = (1/2)(-38 + 6(-15616.3333) - 40579.125) = -225595.7917

x₂(7) = (1/3)(34 + 3(-8009.9167) - 7(40579.125)) = -446726.6667

x₃(7) = (1/2)(20 + 8(-225595.7917) - (-446726.6667)) = 1151638.375

The approximate errors for x₁, x₂, and x₃ are still greater than 0.5%.

Iteration 8:

x₁(8) = (1/2)(-38 + 6(-446726.6667) - 1151638.375) = -8394990.8333

x₂(8) = (1/3)(34 + 3(-225595.7917) - 7(1151638.375)) = -16584928.7083

x₃(8) = (1/2)(20 + 8(-8394990.8333) - (-16584928.7083)) = 42748413.0417

The approximate errors for x₁, x₂, and x₃ are still greater than 0.5%.

Iteration 9:

x₁(9) = (1/2)(-38 + 6(-16584928.7083) - 42748413.0417) = -79510256.375

x₂(9) = (1/3)(34 + 3(-8394990.8333) - 7(42748413.0417)) = -156504968.0417

x₃(9) = (1/2)(20 + 8(-79510256.375) - (-156504968.0417)) = 402466864.2083

The approximate errors for x₁, x₂, and x₃ are still greater than 0.5%.

Iteration 10:

x₁(10) = (1/2)(-38 + 6(-156504968.0417) - 402466864.2083) = -758340798.75

x₂(10) = (1/3)(34 + 3(-79510256.375) - 7(402466864.2083)) = -1489820641.667

x₃(10) = (1/2)(20 + 8(-758340798.75) - (-1489820641.667)) = 3816347893.4583

The approximate errors for x₁, x₂, and x₃ are still greater than 0.5%.

After 10 iterations, the approximate errors for all variables are still above the desired threshold of 0.5%. Therefore, we need to continue the iterations until the desired accuracy is achieved. The number of iterations made so far is 10.

Therefore, the answer obtained by Jacobi method and solving systems of linear equations is 3816347893.4583 with the approximate errors for x₁, x₂, and x₃ are still greater than 0.5% and the number of iterations made so far is 10.

(23 pts) Let X and Y have joint density f XY (x,y)=24xy f XY (x,y)=\ matrix 24xy&x>=0,y>=0,x+y<=1\\ 0&otherwise matrix
Find the marginal density of X / Y
(1)

Answers

To find the marginal density of X/Y, we need to integrate the joint density function fXY(x, y) over the range of Y. By performing the integration, we obtain the marginal density of X/Y as a function of X. The resulting marginal density provides information about the distribution of the ratio X/Y.

The marginal density of X/Y can be obtained by integrating the joint density function fXY(x, y) over the range of Y. In this case, the joint density function is given by:

fXY(x, y) =

  24xy    if x >= 0, y >= 0, and x + y <= 1

  0       otherwise

To find the marginal density of X/Y, we integrate fXY(x, y) with respect to y, while keeping x as a constant. The integration limits for y can be determined based on the given conditions x >= 0, y >= 0, and x + y <= 1. Since y must be non-negative, the lower limit of integration is 0. The upper limit of integration can be determined by the constraint x + y <= 1, which implies y <= 1 - x.

Integrating fXY(x, y) over the range of y, we obtain the marginal density of X/Y as follows:

fX/Y(x) = ∫[0 to (1 - x)] 24xy dy

Evaluating the integral, we have:

fX/Y(x) = 24x * ∫[0 to (1 - x)] y dy

       = 24x * [(y^2)/2] evaluated from 0 to (1 - x)

       = 12x * (1 - x)^2

The resulting marginal density fX/Y(x) represents the distribution of the ratio X/Y. It provides information about the likelihood of different values of X/Y occurring. The shape of the distribution can be further analyzed to understand the characteristics of the random variable X/Y.

Find the limit of the function a. as x-oo and b. as x-> - [infinity]o. 4 g(x) = 5+ (1/x)

Answers

The limit of the function, a. lim(x → +∞) [g(x)] = 5 b. lim(x → -∞) [g(x)] = 5

To find the limits of the function g(x) = 5 + (1/x) as x approaches positive infinity (x → +∞) and negative infinity (x → -∞), we can evaluate the function in these limits.

a. As x approaches positive infinity (x → +∞):

lim(x → +∞) [5 + (1/x)]

As x approaches positive infinity, the term 1/x approaches zero since the denominator becomes larger and larger. Therefore, we have:

lim(x → +∞) [5 + (1/x)] = 5 + 0 = 5

So, the limit of g(x) as x approaches positive infinity is 5.

b. As x approaches negative infinity (x → -∞):

lim(x → -∞) [5 + (1/x)]

As x approaches negative infinity, the term 1/x also approaches zero, but this time the value of x becomes more and more negative. Therefore, we have:

lim(x → -∞) [5 + (1/x)] = 5 + 0 = 5

So, the limit of g(x) as x approaches negative infinity is also 5.

In summary:

a. lim(x → +∞) [g(x)] = 5

b. lim(x → -∞) [g(x)] = 5

The limit of the expression as (x, y) approaches (0, 0) does not exist (DNE).

To find the limit of the expression (x² + y² + 36 - 6) / (1/12(x² + y²)) as (x, y) approaches (0, 0), we can substitute the values of x and y into the expression and simplify:

lim(x,y)→(0,0) [(x² + y² + 36 - 6) / (1/12(x² + y²))]

Substituting x = 0 and y = 0:

= [(0² + 0² + 36 - 6) / (1/12(0² + 0²))]

= [(36 - 6) / (1/12(0))]

= [30 / 0]

Since we have a division by zero (0) in the denominator, the limit is undefined (DNE).

F(x,y)=(sin(x-y), -sin(x-y)) f (x, y) if it exists. (12pts) Given Is F(x, y) conservative? Find the potential function

Answers

The vector field F(x, y) = (sin(x-y), -sin(x-y)) is conservative. The potential function is Φ(x, y) = cos(x-y) + C, where C is a constant.

To determine if the vector field F(x, y) is conservative, we need to check if it satisfies the condition of being a gradient field. A vector field is conservative if it can be expressed as the gradient of a scalar potential function.

Let's compute the partial derivatives of Φ(x, y) with respect to x and y:

∂Φ/∂x = -sin(x-y)

∂Φ/∂y = sin(x-y)

Comparing these derivatives with the components of the given vector field F(x, y), we can see that they match. Therefore, F(x, y) is the gradient of Φ(x, y), and F(x, y) is conservative.

To find the potential function Φ(x, y), we integrate the derivative ∂Φ/∂x with respect to x while treating y as a constant:

∫(-sin(x-y)) dx = -cos(x-y) + g(y)

Here, g(y) represents an arbitrary function of y that may arise during integration. We can simplify this result as:

-∫sin(x-y) dx = cos(x-y) + g(y)

Next, we differentiate the result with respect to y:

∂/∂y (-cos(x-y) + g(y)) = sin(x-y) + ∂g/∂y

Comparing this with the ∂Φ/∂y component of F(x, y), we find that ∂g/∂y = 0, which implies that g(y) is a constant, denoted as C.

Therefore, the potential function Φ(x, y) = cos(x-y) + C, where C is a constant, represents the conservative vector field F(x, y) = (sin(x-y), -sin(x-y)).

The quotient is 2x - 7 and the remainder is 40/(x+5). The slant asymptote is the quotient, which is 2x - 7.

Therefore, the slant asymptote of the function 2x^2 + 3x + 5/(x+5) is y = 2x - 7.

Hope it's understandble...

Answer:

y = 2x + 7

Step-by-step explanation:

A slant asymptote is a type of asymptote that occurs in certain rational functions when the degree of the numerator polynomial is exactly one greater than the degree of the denominator polynomial.

A slant asymptote is a straight line in the form y = mx + c, and its equation is the quotient of the division of the numerator of the function by its denominator.

Therefore, to find the equation of the slant asymptote of the given rational function, divide the numerator 2x² + 3x + 5 by the denominator (x + 5).

Describe something did you do that created an externality. Was it positive or negative? Is there an easy solution to this market failure? Should the failure be fixed? If so, how? Assumptions:1 - Growth in Cost of Living Adjustment is equal to inflation2 - Annual compounding3 - Annual PaymentScenario 1 -You have just graduated from college with your first job at age 25. You plan to retire at age 65 andwant to accumulate $1,000,000 at that time. You plan to contribute annually at the end of each yearinto a retirement account earning 10% interest.Deliverable 1 - Draw a simplified time line and calculate the annual contribution required to reachyour goal.Scenario 2 -Expected inflation is down and rates of return are not what was expected. Your rate of interest isonly 7%.Deliverable 2 - Calculate your annual contribution assuming an interest rate of 7%.Scenario 3 -Your expenses are higher than expected and student loan debt is taking a hit on your income. You decide to defer your retirement plan until you turn 35.Deliverable 3 - Recreate your time line and recalculate the contribution needed to meet your retirement goal.Scenario 4 - Reset all assumptions to scenario 1 (back to the original plan). At age 30 you receive an inheritance from a distant relative. You decide to contribute this $10,000 to your retirement portfolio.Deliverable - Draw a timeline. Add the inheritance to the time line. Calculate your retirement portfolio value at age 30 and add the $10,000. Recalculate the annual contribution required to reach your goal.
