Stokes' Theorem is not satisfied for the given case so it is not true for the given vector field F and surface S.

To verify Stokes' Theorem for the given vector field F and surface S,

calculate the surface integral of the curl of F over S and compare it with the line integral of F around the boundary curve of S.

Let's start by calculating the curl of F,

F(x, y, z) = yi + zj + xk,

The curl of F is given by the determinant,

curl(F) = ∇ x F

          = (d/dx, d/dy, d/dz) x (yi + zj + xk)

Expanding the determinant, we have,

curl(F) = (d/dy(x), d/dz(y), d/dx(z))

           = (0, 0, 0)

The curl of F is zero, which means the surface integral over any closed surface will also be zero.

Now let's consider the hemisphere surface S, defined by x²+ y² + z² = 1, where y ≥ 0, oriented in the direction of the positive y-axis.

The boundary curve of S is a circle in the xz-plane with radius 1, centered at the origin.

According to Stokes' Theorem, the surface integral of the curl of F over S is equal to the line integral of F around the boundary curve of S.

Since the curl of F is zero, the surface integral of the curl of F over S is also zero.

Now, let's calculate the line integral of F around the boundary curve of S,

The boundary curve lies in the xz-plane and is parameterized as follows,

r(t) = (cos(t), 0, sin(t)), 0 ≤ t ≤ 2π

To calculate the line integral,

evaluate the dot product of F and the tangent vector of the curve r(t), and integrate it with respect to t,

∫ F · dr

= ∫ (yi + zj + xk) · (dx/dt)i + (dy/dt)j + (dz/dt)k

= ∫ (0 + sin(t) + cos(t)) (-sin(t)) dt

= ∫ (-sin(t)sin(t) - sin(t)cos(t)) dt

= ∫ (-sin²(t) - sin(t)cos(t)) dt

= -∫ (sin²(t) + sin(t)cos(t)) dt

Using trigonometric identities, we can simplify the integral,

-∫ (sin²(t) + sin(t)cos(t)) dt

= -∫ (1/2 - (1/2)cos(2t) + (1/2)sin(2t)) dt

= -[t/2 - (1/4)sin(2t) - (1/4)cos(2t)] + C

Evaluating the integral from 0 to 2π,

-∫ F · dr

= [-2π/2 - (1/4)sin(4π) - (1/4)cos(4π)] - [0/2 - (1/4)sin(0) - (1/4)cos(0)]

= -π

The line integral of F around the boundary curve of S is -π.

Since the surface integral of the curl of F over S is zero

and the line integral of F around the boundary curve of S is -π,

Stokes' Theorem is not satisfied for this particular case.

Therefore, Stokes' Theorem is not true for the given vector field F and surface S.

The greatest common factor (GCF) of the expression 5t² - 5t - 10 is 5. Factoring the expression, we get: 5t² - 5t - 10 = 5(t² - t - 2).

In the factored form, the GCF, 5, is factored out from each term of the expression. The remaining expression within the parentheses, (t² - t - 2), represents the quadratic trinomial that cannot be factored further with integer coefficients.

To explain the process, we start by looking for a common factor among all the terms. In this case, the common factor is 5. By factoring out 5, we divide each term by 5 and obtain 5(t² - t - 2). This step simplifies the expression by removing the common factor.

Next, we examine the quadratic trinomial within the parentheses, (t² - t - 2), to determine if it can be factored further. In this case, it cannot be factored with integer coefficients, so the factored form of the expression is 5(t² - t - 2), where 5 represents the GCF and (t² - t - 2) is the remaining quadratic trinomial.

There will be approximately 469,224 people living in the town in 20 years.

The population of a town is currently 1928 people and is expected to triple every 4 years. We need to find out how many people will be living there in 20 years.
To solve this problem, we can divide the given time period (20 years) by the time it takes for the population to triple (4 years). This will give us the number of times the population will triple in 20 years.
20 years ÷ 4 years = 5
So, the population will triple 5 times in 20 years.
To find out how many people will be living there in 20 years, we need to multiply the current population (1928) by the factor of 3 for each time the population triples.
1928 * 3 * 3 * 3 * 3 * 3 = 1928 * 3^5
Using a calculator, we can find that 3^5 = 243.
1928 * 243 = 469,224

The property that justifies the statement is the transitive property of equality. The transitive property states that if two elements are equal to a third element, then they must be equal to each other.

In the given statement, we have three equations: A B = B C, BC = CD, and we need to determine if AB = CD. By using the transitive property, we can establish a connection between the given equations.

Starting with the first equation, A B = B C, and the second equation, BC = CD, we can substitute BC in the first equation with CD. This substitution is valid because both sides of the equation are equal to BC.

Substituting BC in the first equation, we get A B = CD. Now, we have established a direct equality between AB and CD. This conclusion is made possible by the transitive property of equality.

The transitive property is a fundamental property of equality in mathematics. It allows us to extend equalities from one relationship to another relationship, as long as there is a common element involved. In this case, the transitive property enables us to conclude that if A B equals B C, and BC equals CD, then AB must equal CD.

An arithmetic sequence is a sequence where the difference between the terms is constant. Hence, the sum of all possible values of n is 69.

To find the sum of all possible values of n of an arithmetic sequence, we need to find the common difference first.

The formula to find the common difference is given by; d = (last term - first term)/(n - 1)

Here, the first term is 535, the last term is 567, and the sequence has n terms.

So;567 - 535 = 32d = 32/(n - 1)32n - 32 = 32n - 32d

By cross-multiplication we get;32(n - 1) = 32d ⇒ n - 1 = d

So, we see that the difference d is one less than n. Therefore, we need to find all factors of 32.

These are 1, 2, 4, 8, 16, and 32. Since n - 1 = d, the possible values of n are 2, 3, 5, 9, 17, and 33. So, the sum of all possible values of n is;2 + 3 + 5 + 9 + 17 + 33 = 69.Hence, the sum of all possible values of n is 69.

(A) To find the probability that a random part has both a scratch and a dent, we can use the formula for the intersection of two events:

P(Scratch and Dent) = P(Scratch) + P(Dent) - P(Scratch or Dent)

Given that P(Scratch) = 0.05, P(Dent) = 0.02, and P(Scratch or Dent) = 0.06, we can substitute these values into the formula:

P(Scratch and Dent) = 0.05 + 0.02 - 0.06 = 0.01

Therefore, the probability that a random part has both a scratch and a dent is 0.01.

(B) To find the probability that a random part has a scratch given it has a dent, we can use the formula for conditional probability:

P(Scratch | Dent) = P(Scratch and Dent) / P(Dent)

We already found that P(Scratch and Dent) = 0.01. To find P(Dent), we can use the probability of either a scratch or a dent happening:

P(Dent) = 0.02

Substituting these values into the formula, we have:

P(Scratch | Dent) = 0.01 / 0.02 = 0.50

Therefore, the probability that a random part has a scratch given it has a dent is 0.50.

(C) To determine whether the events "there is a scratch" and "there is a dent" are independent, we can compare the probability of their intersection to the product of their individual probabilities.

If the events are independent, then P(Scratch and Dent) = P(Scratch) * P(Dent).

We found that P(Scratch and Dent) = 0.01, P(Scratch) = 0.05, and P(Dent) = 0.02. Let's check if the equation holds:

0.01 ≠ (0.05 * 0.02)

Since the equation does not hold, the events "there is a scratch" and "there is a dent" are not independent.

(D) To find the probability that a random part has a scratch or a dent, but not both, we can subtract the probability of both events happening from the probability of either event happening:

P(Scratch or Dent but not both) = P(Scratch or Dent) - P(Scratch and Dent)

We already found that P(Scratch or Dent) = 0.06 and P(Scratch and Dent) = 0.01. Substituting these values into the formula:

P(Scratch or Dent but not both) = 0.06 - 0.01 = 0.05

The rate at which the intensity of the moonlight is changing, with respect to time, is given by -6a millilux per second.

To determine the rate at which the intensity of the moonlight is changing, we need to apply the chain rule and use the equation provided in the previous problem.

The equation of the ground shape is given as z = -0.1x³ - 0.3x + 0.2y² + 1, where x, y, and z are measured in meters. Edward is running along the contour z = -2, which means his position on the ground satisfies the equation -2 = -0.1x³ - 0.3x + 0.2y² + 1.

To find the rate of change of the moonlight intensity, we need to differentiate the equation with respect to time. Since Jacob's velocity is +3x + 9/2 m/s, we can express his position as x = 2t and y = 2t.

Differentiating the equation of the ground shape with respect to time using the chain rule, we have:

dz/dt = (dz/dx)(dx/dt) + (dz/dy)(dy/dt)

Substituting the values of x and y, we have:

dz/dt = (-0.3(2t) - 0.9 + 0.2(4t)(4)) * (3(2t) + 9/2)

Simplifying the expression, we get:

dz/dt = (-0.6t - 0.9 + 3.2t)(6t + 9/2)

Further simplifying and combining like terms, we have:

dz/dt = (2.6t - 0.9)(6t + 9/2)

Now, we know that dz/dt represents the rate at which the ground's shape is changing, and the intensity of the moonlight is inversely proportional to the ground's shape. Therefore, the rate at which the intensity of the moonlight is changing is the negative of dz/dt multiplied by the intensity function a.

So, the rate of change of the intensity of the moonlight is given by:

dI/dt = -a(2.6t - 0.9)(6t + 9/2)

Simplifying this expression, we get:

dI/dt = -6a(2.6t - 0.9)(3t + 9/4)

Thus, the rate at which the intensity of the moonlight is changing, with respect to time, is given by -6a millilux per second.

In conclusion, the detailed calculation using the chain rule leads to the rate of change of the moonlight intensity as -6a millilux per second.

The first part of the investment is $48,000.

The amount for the second part is $12,000.

The amount for the third part is $41,000.

First, we find the first part of the investment. We shall x to represent the first part:

Given, the second part of the investment is (1/4)th of the interest from the first investment.

So, the second part is (1/4) * x = x/4.

The third part:

Third part = Total investment - (First part + Second part)

Third part = 101000 - (x + x/4) = 101000 - (5x/4) = 404000/4 - 5x/4 = (404000 - 5x)/4.

Compute the interest from each part of the investment:

First part = x * 8% = 0.08x

Second part = (x/4) * 6% = 0.06x/4 = 0.015x

Third part = [(404000 - 5x)/4] * 9% = 0.09 * (404000 - 5x)/4 = 0.0225 * (404000 - 5x)

Since the total interest earned is $7650.

So, we set up the equation for this:

0.08x + 0.015x + 0.0225 * (404000 - 5x) = 7650

Simplifying:

0.08x + 0.015x + 0.0225 * 404000 - 0.0225 * 5x = 7650

0.08x + 0.015x + 9090 - 0.1125x = 7650

0.0825x + 9090 - 0.1125x = 7650

-0.03x = 7650 - 9090

-0.03x = -1440

x = -1440 / -0.03

x = 48,000

Thus, the first part of the investment is $48,000.

Now we shall get the amount for the second and third parts of the investment:

The second part of the investment is (1/4) * x,

where x = the value of the first part.

Second part = (1/4) * $48,000

Second part = $12,000

Finally, the amount for investment 3:

Third part = Total investment - (First part + Second part)

Third part = $101,000 - ($48,000 + $12,000)

Third part = $101,000 - $60,000

Third part = $41,000

Hence, the amounts of the three parts of the investment are:

To solve this problem using diagonalization, we can set up a matrix representing the transition probabilities between the groups over time. Let's denote the number of students in each group at month t as [A(t), B(t), C(t)], and the transition matrix as T.

The transition matrix T is given by:

T = [0.75 0.25 0; 0.5 0.5 0; 0 0.5 0.5]

The columns of the matrix represent the probability of moving from one group to another. For example, the first column [0.75 0.5 0] represents the probabilities of moving from group A to group A, group B, and group C, respectively.

a. To find the number of students in each group after 1 month, we can calculate T multiplied by the initial number of students in each group:

[A(1), B(1), C(1)] = T * [150, 450, 400]

Calculating this product, we get:

[A(1), B(1), C(1)] = [112.5, 387.5, 450]

Rounding to the nearest integers, we have:

Group A: 113

Group B: 388

Group C: 450

b. To estimate the number of students in each group after 10 months using diagonalization, we can diagonalize the transition matrix T. Diagonalization involves finding the eigenvectors and eigenvalues of the matrix.

The eigenvalues of T are:

λ₁ = 1

λ₂ = 0.75

λ₃ = 0

The corresponding eigenvectors are:

v₁ = [1 1 1]

v₂ = [1 -1 0]

v₃ = [0 1 -2]

We can write the diagonalized form of T as:

D = [1 0 0; 0.75 0 0; 0 0 0]

To find the matrix P that diagonalizes T, we need to stack the eigenvectors v₁, v₂, and v₃ as columns in P:

P = [1 1 0; 1 -1 1; 1 0 -2]

We can calculate the matrix P⁻¹:

P⁻¹ = [1/2 1/2 0; 1/4 -1/4 1/2; 1/4 1/4 -1/2]

Now, we can find the matrix S, where S = P⁻¹ * [A(0), B(0), C(0)], and [A(0), B(0), C(0)] represents the initial number of students in each group:

S = P⁻¹ * [150, 450, 400]

Calculating this product, we get:

S = [550, -50, 100]

Finally, to find the number of students in each group after 10 months, we can calculate:

[A(10), B(10), C(10)] = P * D¹⁰ * S

Calculating this product, we get:

[A(10), B(10), C(10)] = [600, 100, 300]

The given points (1,1,3), (-6,-5,0), (-4,-2,-7), and (3,4,-4) form the vertices of a parallelogram.

To determine if the given points form the vertices of a parallelogram, we can use the properties of parallelograms. One of the properties of a parallelogram is that opposite sides are parallel.

Let's denote the points as A(1,1,3), B(-6,-5,0), C(-4,-2,-7), and D(3,4,-4). We can calculate the vectors corresponding to the sides of the quadrilateral: AB = B - A, BC = C - B, CD = D - C, and DA = A - D.

If AB is parallel to CD and BC is parallel to DA, then the given points form a parallelogram.

Calculating the vectors:

AB = (-6,-5,0) - (1,1,3) = (-7,-6,-3)

CD = (3,4,-4) - (-4,-2,-7) = (7,6,3)

BC = (-4,-2,-7) - (-6,-5,0) = (2,3,-7)

DA = (1,1,3) - (3,4,-4) = (-2,-3,7)

We can observe that AB and CD are scalar multiples of each other, and BC and DA are scalar multiples of each other. Therefore, AB is parallel to CD and BC is parallel to DA.

Hence, based on the fact that the opposite sides are parallel, we can conclude that the given points (1,1,3), (-6,-5,0), (-4,-2,-7), and (3,4,-4) form the vertices of a parallelogram.

To find the maximum value of f(x,y) = e^(2xy) subject to the constraint x^3 + y^3 = 16, we introduce a Lagrange multiplier λ and set up the following equations:

∇f = λ∇g, where ∇f and ∇g are the gradients of f and the constraint g, respectively.

g(x, y) = x^3 + y^3 - 16

Taking the partial derivatives, we have:

∂f/∂x = 2ye^(2xy)

∂f/∂y = 2xe^(2xy)

∂g/∂x = 3x^2

∂g/∂y = 3y^2

Setting up the system of equations, we have:

2ye^(2xy) = 3λx^2

2xe^(2xy) = 3λy^2

x^3 + y^3 = 16

Solving this system of equations will yield the critical points. From there, we can determine which points satisfy the constraint and find the maximum value of f(x,y) on the feasible region.

0.5 ml per hookworm x 1000 hookworms = 500 ml of host blood per day.

The percentage of total blood volume lost daily:

500 ml lost blood / 5000 ml total blood volume of an average adult human x 100% = 10%

In summary, for a severe nematode infection, an individual may lose 500 milliliters of blood per day. That translates to a loss of 10% of the total blood volume of an average adult human.

To find the values of x ≥ 0 and y ≥ 0 that maximize z = 12x + 15y subject to the given constraints, let's analyze each set of constraints: (a) x + y ≤ 19

The feasible region for this constraint is a triangular region below the line x + y = 19. Since the objective function z = 12x + 15y is increasing as we move in the direction of larger x and y, the maximum value of z occurs at the vertex of this region that lies on the line x + y = 19.

The vertex with the maximum value is (x, y) = (19, 0).

Therefore, the maximum value occurs at the ordered pair (19, 0).

The correct choice is:

A. The maximum value occurs at (19, 0)

To find Jessica's monthly payment, we can use the formula for calculating the monthly payment on an amortized loan:

P = (r * A) / (1 - (1 + r)^(-n))

Where:

P is the monthly payment

r is the monthly interest rate (5.6% / 12)

A is the loan amount ($53,000)

n is the total number of payments (15 years * 12 months per year)

(a) Calculating the monthly payment:

r = 5.6% / 12 = 0.0467 (rounded to 4 decimal places)

n = 15 * 12 = 180

P = (0.0467 * 53000) / (1 - (1 + 0.0467)^(-180))

P ≈ $416.68

So, Jessica's monthly payment is approximately $416.68.

(b) To find the total amount repaid, we multiply the monthly payment by the total number of payments:

Total amount repaid = P * n

Total amount repaid ≈ $416.68 * 180

Total amount repaid ≈ $75,002.40

Therefore, Jessica's total amount to repay the loan is approximately $75,002.40.

(c) To find the total amount of interest paid, we subtract the loan amount from the total amount repaid:

Total interest paid = Total amount repaid - Loan amount

Total interest paid ≈ $75,002.40 - $53,000

Total interest paid ≈ $22,002.40

So, Jessica will pay approximately $22,002.40 in total interest over the term of the loan.

The electrostatic potential maps for cycloheptatrienone and cyclopentadienone reflect their respective aromatic ring sizes, with cycloheptatrienone exhibiting more delocalization and a more evenly distributed potential.

The electrostatic potential maps for cycloheptatrienone and cyclopentadienone can be compared to understand their electronic distributions and reactivity. Cycloheptatrienone consists of a seven-membered carbon ring with a ketone group, while cyclopentadienone has a five-membered carbon ring with a ketone group.

In terms of electrostatic potential maps, cycloheptatrienone is expected to exhibit a more delocalized electron distribution compared to cyclopentadienone. This is due to the larger aromatic ring in cycloheptatrienone, which allows for more extensive resonance stabilization and electron delocalization. As a result, cycloheptatrienone is likely to have a more evenly distributed electrostatic potential across its molecular structure.

On the other hand, cyclopentadienone with its smaller aromatic ring may show a more localized electron distribution. The electrostatic potential map of cyclopentadienone might display regions of higher electron density around the ketone group and localized areas of positive or negative potential.

The equation of the line parallel to x - 5y = -6 and containing the point (0, 0) is y = (1/5)x.

To find the equation of a line parallel to the line given by the equation x - 5y = -6, we can use the fact that parallel lines have the same slope.

First, let's rearrange the given equation in slope-intercept form (y = mx + b), where m represents the slope:

x - 5y = -6

-5y = -x - 6

y = (1/5)x + (6/5)

The slope of the given line is 1/5. Since the line we're looking for is parallel, it will also have a slope of 1/5.

Now, we have the slope (m = 1/5) and a point on the line (0, 0). We can use the point-slope form of the equation of a line to find the equation:

y - y₁ = m(x - x₁)

Substituting the values of the point (0, 0):

y - 0 = (1/5)(x - 0)

Simplifying:

y = (1/5)x

Therefore, the equation of the line parallel to x - 5y = -6 and containing the point (0, 0) is y = (1/5)x.

The vector points to the northeast, so the approximate direction of the velocity relative to the ground is northeast.

* Velocity of the plane in calm air: 150 mi/hr due east (i)

* Velocity of the crosswind: 30 mi/hr in the southwest direction (-1/2i - 1/2j)

* Velocity of the updraft: 20 mi/hr upward (k)

To find the resulting velocity of the plane, we add up the vector components:

Code snippet

Resultant velocity = velocity of plane + velocity of crosswind + velocity of updraft

= i + (-1/2i - 1/2j) + k

= (150 - 15/2)i - 15/2j + 20k

= 120i - 15j + 20k

Code snippet

The magnitude of the resultant velocity can be found using the Pythagorean theorem:

Code snippet

|Resultant velocity| = √(120² + (-15)² + 20²)

≈ 130.6 mi/hr

To describe the approximate direction of the velocity relative to the ground, we can use a sketch. Draw a coordinate system with the x-axis pointing east, the y-axis pointing north, and the z-axis pointing upward. Then, draw a vector representing the resultant velocity we found above. The direction of the vector will give us the approximate direction of the velocity relative to the ground.

A) The probability that both dice show 5 is 1/36.

B) The probability that one dice shows a 5 and the other does not is 11/36.

C) The probability that neither dice shows a 5 is 25/36.

A) To find the probability that both dice show 5, we need to determine the favorable outcomes (where both dice show 5) and the total number of possible outcomes when two dice are thrown.

Favorable outcomes: There is only one possible outcome where both dice show 5.

Total possible outcomes: When two dice are thrown, there are 6 possible outcomes for each dice. Since we have two dice, the total number of outcomes is 6 multiplied by 6, which is 36.

Therefore, the probability that both dice show 5 is the number of favorable outcomes divided by the total possible outcomes, which is 1/36.

B) To find the probability that one dice shows a 5 and the other does not, we need to determine the favorable outcomes (where one dice shows a 5 and the other does not) and the total number of possible outcomes.

Favorable outcomes: There are 11 possible outcomes where one dice shows a 5 and the other does not. This can occur when the first dice shows 5 and the second dice shows any number from 1 to 6, or vice versa.

Total possible outcomes: As calculated before, the total number of outcomes when two dice are thrown is 36.

Therefore, the probability that one dice shows a 5 and the other does not is 11/36.

C) To find the probability that neither dice shows a 5, we need to determine the favorable outcomes (where neither dice shows a 5) and the total number of possible outcomes.

Favorable outcomes: There are 25 possible outcomes where neither dice shows a 5. This occurs when both dice show any number from 1 to 4, or both dice show 6.

Total possible outcomes: As mentioned earlier, the total number of outcomes when two dice are thrown is 36.

Therefore, the probability that neither dice shows a 5 is 25/36.

According to the Question, The interest earned in 4 years is $1,954.83.

What is compounded quarterly?

A quarterly compounded rate indicates that the principal amount is compounded four times over one year. According to the compounding process, if the compounding time is longer than a year, the investors would receive larger future values for their investment.

The principal is $10,000.

The annual interest rate is 4.5%, which is compounded quarterly.

Since there are four quarters in a year, the quarterly interest rate can be calculated by dividing the annual interest rate by four.

The formula for calculating the future value of a deposit with quarterly compounding is:

[tex]P = (1 + \frac{r}{n})^{nt}[/tex]

Where P is the principal

The annual interest rate is the number of times the interest is compounded in a year (4 in this case)

t is the number of years

The interest earned equals the future value less the principle.

Therefore, the interest earned can be calculated as follows: I = FV - P

where I = the interest earned and FV is the future value.

Substituting the given values,

[tex]P = $10,000r = 4.5/4 = 1.125n = 4t = 4 years[/tex]

The future value is:

[tex]FV = $10,000(1 + 1.125/100)^{4 *4} = $11,954.83[/tex]

Therefore, the interest earned is:

[tex]I = $11,954.83 - $10,000= $1,954.83[/tex]

Thus, the interest earned in 4 years is $1,954.83.

First, let's find the determinant of the coefficient matrix, D:

D = |2  3 -1| = 2(-1) - 3(1) = -5

Next, we need to find the determinant of the matrix obtained by replacing the coefficients of the y-variable with the constants of the equations. Let's call this matrix Dx:

Dx = |2  3 -1| = 2(-1) - 3(1) = -5

Similarly, we find the determinant Dy by replacing the coefficients of the x-variable with the constants:

Dy = |2  3 -1| = 2(3) - 2(-1) = 8

Finally, we calculate the determinant Dz by replacing the coefficients of the z-variable with the constants:

Dz = |2  3 -1| = 2(4) - 3(3) = -1

Now, we can find the value of y using Cramer's rule:

y = Dy / D = 8 / -5 = -8/5

Therefore, the solution to the linear system of equations for y only is y = -8/5.

To find a solution to the ordinary differential equation (ODE) \(y' = -y\) with the initial condition \(y(0) = 1\), we can use the method of successive approximations.

This method involves iteratively improving the approximation of the solution by using the previous approximation as a starting point for the next iteration. In this case, we start by assuming an initial approximation for the solution, let's say \(y_0(x) = 1\). Then, we can use this initial approximation to find a better approximation by considering the differential equation \(y' = -y\) as \(y' = -y_0\) and solving it for \(y_1(x)\).

We repeat this process, using the previous approximation to find the next one, until we reach a desired level of accuracy. In each iteration, we find that \(y_n(x) = 1 - x + \frac{x^2}{2!} - \frac{x^3}{3!} + \ldots + (-1)^n \frac{x^n}{n!}\). As we continue this process, the terms with higher powers of \(x\) become smaller and approach zero. Therefore, the solution to the ODE is given by the limit as \(n\) approaches infinity of \(y_n(x)\), which is the infinite series \(y(x) = \sum_{n=0}^{\infty} (-1)^n \frac{x^n}{n!}\).

This infinite series is a well-known function called the exponential function, and we can recognize it as \(y(x) = e^{-x}\). Thus, using the method of successive approximations, we find that the solution to the given ODE with the initial condition \(y(0) = 1\) is \(y(x) = e^{-x}\).
