Suppose that 53% of families living in a certain country own a minivan and 24% own a SUV. The addition rule mightsuggest, then, that 77% of families own either a minivan or a SUV. What's wrong with that reasoning?
Choose the correct answer below.
A. If one family owns a minivan or a SUV, it can influence another family to also own a minivan or a SUV. The events are not independent, so the addition rule does not apply.
B.The sum of the probabilities of the two given events does not equal 1, so this is not a legitimate probability assignment.
C. A family may own both a minivan and a SUV. The events are not disjoint, so the addition rule does not apply.
D. The reasoning is correct. Thus, 77% a minivan or a SUV.

The result of evaluating P(1/3) using synthetic division is:

P(1/3) = 9x^2 - 7x - 7/3

To evaluate P(1/3) using synthetic division, we'll set up the synthetic division table as follows:

Copy code

 |    9    -10    0    4

1/3 |_________________________

First, we write down the coefficients of the polynomial P(x) in descending order: 9, -10, 0, 4. Then we bring down the 9 (the coefficient of the highest power of x) as the first value in the second row.

Next, we multiply the divisor, 1/3, by the number in the second row and write the result below the next coefficient. Multiply: (1/3) * 9 = 3.

Copy code

 |    9    -10    0    4

1/3 | 3

Add the result, 3, to the next coefficient in the first row: -10 + 3 = -7. Write this value in the second row.

Copy code

 |    9    -10    0    4

1/3 | 3 -7

Again, multiply the divisor, 1/3, by the number in the second row and write the result below the next coefficient: (1/3) * -7 = -7/3.

Copy code

 |    9    -10    0    4

1/3 | 3 -7 -7/3

Add the result, -7/3, to the next coefficient in the first row: 0 + (-7/3) = -7/3. Write this value in the second row.

Copy code

 |    9    -10    0    4

1/3 | 3 -7 -7/3

Finally, multiply the divisor, 1/3, by the number in the second row and write the result below the last coefficient: (1/3) * (-7/3) = -7/9.

Copy code

 |    9    -10    0    4

1/3 | 3 -7 -7/3

____________

9 -7 -7/3 4

The bottom row represents the coefficients of the resulting polynomial after the synthetic division. The first value, 9, is the coefficient of x^2, the second value, -7, is the coefficient of x, the third value, -7/3, is the constant term.

Thus, the result of evaluating P(1/3) using synthetic division is:

P(1/3) = 9x^2 - 7x - 7/3

Please note that the remainder in this case is 4, which is not used to determine P(1/3) since it represents a constant term.

Assuming you are trying to solve for the variable "a," you should first multiply each side by 2 to cancel out the 2 in the denominator in 5/2. Your equation will then look like this:

(8a+2)/(2a-1) = 5

Then, you multiply both sides by (2a-1) to cancel out the (2a-1) in (8a+2)/(2a-1)

Your equation should then look like this:

8a+2 = 10a-5

Subtract 2 on both sides:

8a=10a-7

Subtract 10a on both sides:

-2a=-7

Finally, divide both sides by -2

The maximum point of the curve is approximately (2.069, 15.848), and there is no minimum point.

To find the maximum and minimum points of the curve y = 5x - x^2/2 + 3/√x, we need to take the derivative of the function and set it equal to zero.

y = 5x - x^2/2 + 3/√x

y' = 5 - x/2 - 3/2x^(3/2)

Setting y' equal to zero:

0 = 5 - x/2 - 3/2x^(3/2)

Multiplying both sides by 2x^(3/2):

0 = 10x^(3/2) - x√x - 3

This is a cubic equation, which can be solved using the cubic formula. However, it is a very long and complicated formula, so we will use a graphing calculator to find the roots of the equation.

Using a graphing calculator, we find that the roots of the equation are approximately x = 0.019, x = 2.069, and x = -2.088. The negative root is extraneous, so we discard it.

Next, we need to find the second derivative of the function to determine if the critical point is a maximum or minimum.

y'' = -1/2 - (3/4)x^(-5/2)

Plugging in the critical point x = 2.069, we get:

y''(2.069) = -0.137

Since y''(2.069) is negative, we know that the critical point is a maximum.

Therefore, the maximum point of the curve is approximately (2.069, 15.848).

To find the minimum point of the curve, we need to check the endpoints of the domain. The domain of the function is x > 0, so the endpoints are 0 and infinity.

Checking x = 0, we get:

y(0) = 0 + 3/0

This is undefined, so there is no minimum at x = 0.

Checking as x approaches infinity, we get:

y(infinity) = -infinity

This means that there is no minimum as x approaches infinity.

tan(θ) = -√35,

csc(θ) = -6√35/35,

cot(θ) = -√35/35.

Given that sec(θ) = 6 and θ is in Quadrant IV, we can find the values of the remaining trigonometric functions as follows:

First, we know that sec(θ) is the reciprocal of cos(θ).Therefore, if sec(θ) = 6, then cos(θ) = 1/6.

Since theta is in Quadrant IV, we know that the cosine is positive and the sine is negative. Therefore, sin(θ) = -√(1 - cos²(θ)) = -√(1 - (1/6)²) = -√(1 - 1/36) = -√(35/36) = -√35/6.

Using sin(θ) and cos(θ), we can find the remaining trigonometric functions:

tan(θ) = sin(θ) / cos(θ) = (-√35/6) / (1/6) = -√35.

csc(θ) = 1 / sin(θ) = 1 / (-√35/6) = -6/√35 = -6√35/35 = -6√35/35.

The secret is s=(4,5,7,2,3,6). Throughout this question, we will be working in mod11. Consider the problem of sharing a secret among n people such that at least k≤n of them must collude to retrieve it. We will do so by method of intersecting hyperplanes. The dealer's algorithm for distributing the secret can be outlined as:-

Select a point (s0,s1,…,sn) that is secret.- For 1≤i≤k and 0≤j≤n, set arbitrary values for aij and find ci such that ci≡sn−(∑j=0n−1aijsj)(mod11)- Define the ith hyperplane as −ci≡(∑j=0n−1aijxj)−xn(mod11)- Distribute the hyperplanes to each of the n participants.

Retrieving the secret is then trivially equivalent to solving the corresponding matrix problem. Compute an actual example of the dealer's algorithm along with secret extraction with n=6,k=3.

For this problem, we have k=3 and n=6. We need to select a secret point s0,s1,…,sn which is a secret.

For this problem, let us take secret point s0=4, s1=5, s2=7, s3=2, s4=3, and s5=6. That is s=(4,5,7,2,3,6).

Now, we need to select the arbitrary values of aij for 1≤i≤k and 0≤j≤n.

We have k=3, n=6, therefore i=1,2,3 and j=0,1,2,3,4,5.

Let's take the arbitrary values of aij as shown below:

a11=1,a12=1,a13=0,a14=0,a15=0,a16=0a21=1,a22=0,a23=1,a24=0,a25=0,a26=0a31=0,a32=1,a33=1,a34=0,a35=0,a36=0

From the above, we need to find the values of ci. We can write the equation as below:

ci≡sn−(∑j=0n−1aijsj)(mod11)For i=1,2,3 and j=0,1,2,3,4,5.

Let's calculate ci as shown below:

c1= 4(1) + 5(1) = 9c2= 4(1) + 7(1) = 2c3= 5(1) + 7(1) = 0

Thus, we have c=(9,2,0).For the ith hyperplane, we can write the equation as below:

-ci≡(∑j=0n−1aijxj)−xn(mod11)For i=1,2,3 and j=0,1,2,3,4,5.

Let's calculate the ith hyperplane as shown below:H1: −9≡x0+x1(mod11)H2: −2≡x0+x2(mod11)H3: 0≡x1+x2(mod11)

The above are the hyperplanes, we can distribute these hyperplanes to each of the n participants and retrieving the secret is then trivially equivalent to solving the corresponding matrix problem.

We can write the above system of equations as below:x0=−9−x1(mod11)x0=−2−x2(mod11)x1=−x2(mod11)

Now, let's find the values of x1 and x2 as shown below:x1=−x2(mod11)x0=−2−x2(mod11)=−2−x1(mod11)=−2−(−x2)(mod11)=−2+x2(mod11)So, we get x2=10, x1=1, and x0=0.Thus, the secret is s=(4,5,7,2,3,6).

A) Rate of change = -3.

B) When s = 0, r has a value of 18.

C) The formula that represents r in terms of s is r = -3s + 18.

D) The formula that represents Δr in terms of s is Δr = -3.
E) i. True

   ii. False

   iii. True

   iv. False

Given that a table representing the values of r and s we need to determine the answers asked related to their values,

A) To find the formula that represents Δr in terms of Δs, we can calculate the rate of change of r with respect to s using the given data points:

Δr = r₂ - r₁

Δs = s₂ - s₁

From the given table, we can calculate Δr and Δs for the first two data points:

Δr₁ = 9 - 15 = -6

Δs₁ = 3 - 1 = 2

Now, we can find the constant rate of change of r with respect to s:

Rate of change = Δr₁ / Δs₁

= -6/2

Rate of change = -3.

B) To find the value of r when s = 0, we need to determine the equation of the line that represents the relationship between r and s. We can use the data points given to calculate the slope (rate of change) and then find the equation using the point-slope form.

Using the first and second data points:

slope (m) = Δr/Δs = (-6)/(2) = -3

Now, we can use the point-slope form with the point (1, 15) (as it is the first data point) to find the equation:

y - y₁ = m(x - x₁)

r - 15 = -3(s - 1)

r - 15 = -3s + 3

r = -3s + 18

So, when s = 0, we can substitute s into the equation to find the value of r:

r = -3(0) + 18

r = 18

Therefore, when s = 0, r has a value of 18.

C) To define a formula that represents r in terms of s, we can use the concept of a linear equation. We can find the equation of a line passing through the given data points (1, 15) and (3, 9):

Using the point-slope form of a linear equation:

y - y₁ = m(x - x₁)

m = (r₂ - r₁) / (s₂ - s₁) = (-6) / (2) = -3

Using the point (1, 15):

r - 15 = -3(s - 1)

r - 15 = -3s + 3

r = -3s + 18

Thus, the formula that represents r in terms of s is r = -3s + 18.

D) To define a formula that represents Δr in terms of s, we can differentiate the equation for r in terms of s:

r = -3s + 18

Taking the derivative with respect to s:

d(r)/d(s) = -3

Therefore, the formula that represents Δr in terms of s is Δr = -3.

E) Let's evaluate the given statements:

i. The graph that represents r in terms of s is linear.

True. Since the equation r = -3s + 18 represents a linear relationship between r and s, the graph will be a straight line.

ii. r is proportional to s.

False. The equation r = -3s + 18 does not indicate a direct proportionality between r and s, as the coefficient of s is -3, not a constant.

iii. Δr is proportional to Δs.

True. The rate of change of r with respect to s is constant (-3), indicating that Δr is directly proportional to Δs.

iv. The graph of r in terms of s is a straight line that passes through the origin (0,0).

False. The equation r = -3s + 18 does not include the point (0,0). Therefore, the graph will not pass through the origin.

An independent set of G is a subset of the vertices U ⊆ V such that no two vertices in U are connected by an edge of G. Give a O(|V|+|E|)-time algorithm to find an independent set of size ≥ |V|/2 in G. The overall time complexity is O(|V|+|E|).

To find an independent set of size ≥ |V|/2 in a bipartite graph G = (V, E), we can utilize the property of bipartite graphs that they can be 2-colored. Here is an algorithm that achieves this in O(|V|+|E|) time:

1. Initialize an empty set U to store the vertices of the independent set.

2. Perform a 2-coloring of the bipartite graph G. This can be done using a modified depth-first search (DFS) algorithm:

  - Choose an arbitrary starting vertex v from V.

  - Color v with one color (e.g., color 1) and add it to U.

  - Perform a DFS traversal of G, starting from v, and assign the opposite color (e.g., color 2) to each adjacent vertex.

  - If at any point during the DFS traversal, a vertex is encountered that has already been colored, skip it and continue the traversal.

  - Repeat the process for any remaining unvisited vertices until all vertices have been colored.

3. Compare the sizes of the two color classes in the 2-coloring. Let's assume that one color class has size p and the other has size q, where p + q = |V|. Without loss of generality, assume p ≤ q.

4. If p ≥ q/2, return U as the independent set since it has size ≥ |V|/2.

5. Otherwise, iterate over the vertices in U and remove vertices of color 2 until the size of U becomes ≥ |V|/2. Since the size of the smaller color class is p, we can remove at most p vertices of color 2 to satisfy this condition.

6. Return the modified U as the independent set with size ≥ |V|/2.

The time complexity of this algorithm is dominated by the 2-coloring step, which can be performed in O(|V|+|E|) time using a modified DFS traversal. The subsequent steps involve simple comparisons and removals, which can be done in O(|V|) time.

The power rule states that for a function of the form f(x) = ax^n, the derivative is given by f'(x) = anx^(n-1).

Using the power rule, we can differentiate each term of the function:

1. Differentiating 3t^(13/3):

The derivative of 3t^(13/3) is (13/3) * 3t^(13/3 - 1) = 39t^(10/3).

2. Differentiating -2t^(7/4):

The derivative of -2t^(7/4) is (7/4) * -2t^(7/4 - 1) = -7/2 * t^(3/4).

3. Differentiating -t^(1/2):

The derivative of -t^(1/2) is (1/2) * -t^(1/2 - 1) = -(1/2) * t^(-1/2) = -(1/2) / √t.

4. The derivative of the constant term 1 is 0 since the derivative of a constant is always zero.

Combining all the derivatives, we have:

z' = 39t^(10/3) - 7/2 * t^(3/4) - (1/2) / √t.

Therefore, the derivative of the function z = 3t^(13/3) - 2t^(7/4) - t^(1/2) + 1 is z' = 39t^(10/3) - 7/2 * t^(3/4) - (1/2) / √t.

The unit tangent vector of the parameterized curve r(t) = ⟨28t, 2, t^7⟩ at t = -2 does not exist.

To find the unit tangent vector, we need to differentiate the given vector function r(t) with respect to t. The unit tangent vector is obtained by normalizing the resulting derivative.

The derivative of r(t) with respect to t is:

r'(t) = ⟨28, 0, 7t^6⟩

To find the unit tangent vector at t = -2, we substitute the value into the derivative:

r'(-2) = ⟨28, 0, 7(-2)^6⟩ = ⟨28, 0, 7(64)⟩ = ⟨28, 0, 448⟩

Next, we calculate the magnitude of the tangent vector:

| r'(-2) | = √(28^2 + 0^2 + 448^2) = √(784 + 200704) = √201488 = 449.08

Finally, we divide the derivative vector by its magnitude to obtain the unit tangent vector:

T(-2) = r'(-2) / | r'(-2) | = ⟨28/449.08, 0/449.08, 448/449.08⟩ ≈ ⟨0.0623, 0, 0.9978⟩

At t = -2, the unit tangent vector of the parameterized curve r(t) = ⟨28t, 2, t^7⟩ does not exist. This is because the derivative vector, when normalized, yields a magnitude of 449.08, which is not zero. Thus, we can conclude that there is no unit tangent vector at t = -2.

Therefore, the approximate average volume of air in the lungs during one respiratory cycle is 1.4825 liters.

To approximate the average volume of air in the lungs during one respiratory cycle, we need to find the average value of the function V(t) over the interval from 0 to 5 seconds. The average value of a function f(x) over an interval [a, b] is given by:

Average value = (1 / (b - a)) * ∫[a, b] f(x) dx

In this case, we have [tex]V(t) = 0.1729t + 0.1522t^2 - 0.0374t^3[/tex], and we need to find the average value over the interval [0, 5].

The differential equation would have the form dy/dx = f(x, y), where f(x, y) represents the relationship between x, y, and the slope of the tangent line at any given point on the circle.

To write a differential equation of the form dy/dx = f(x, y) having the function g(x) as its solution, we can use the fact that the derivative dy/dx represents the slope of the tangent line to the graph of the function. By analyzing the geometric properties provided for the function g(x), we can determine the appropriate form of the differential equation.

For example, if the geometric property states that the graph of g(x) is a straight line, we know that the slope of the tangent line is constant. In this case, we can write the differential equation as dy/dx = m, where m is the slope of the line.

If the geometric property states that the graph of g(x) is a circle, we know that the derivative dy/dx is dependent on both x and y, as the slope of the tangent line changes at different points on the circle. In this case, the differential equation would have the form dy/dx = f(x, y), where f(x, y) represents the relationship between x, y, and the slope of the tangent line at any given point on the circle.

The specific form of the differential equation will depend on the geometric property described for the function g(x) in each problem. By identifying the key characteristics of the graph and understanding the relationship between the slope of the tangent line and the variables x and y, we can formulate the appropriate differential equation that represents the given geometric property.

Step-by-step explanation:

Both function are always increasing so D is correct.

The slope of the line tangent to the curve y = x^3 - 36x + 4 at the point (6, 4) is 72 (option c).

To find the slope of the tangent line at a specific point on the curve, we need to find the derivative of the function and evaluate it at that point.

Taking the derivative of the given function y = x^3 - 36x + 4 with respect to x, we get dy/dx = 3x^2 - 36.

To find the slope at the point (6, 4), we substitute x = 6 into the derivative: dy/dx = 3(6)^2 - 36 = 3(36) - 36 = 72 - 36 = 36.

Therefore, the slope of the tangent line to the curve at the point (6, 4) is 36. Since none of the provided options match, it seems there might be a mistake in the options given. The correct answer based on the explanation is 36, not 72 as indicated in the options.

The amount that represents the 55th percentile for this distribution is 51.3 ounces.

The amount that represents the 55th percentile for this distribution is 51.3 ounces. We can determine this as follows:

Solution We have the mean (μ) = 50.2 ounces and the standard deviation (σ) = 3.7 ounces.

The formula to determine the x value that corresponds to a given percentile (p) for a normally distributed variable is given by: x = μ + zσwhere z is the z-score that corresponds to the percentile p.

Since we need to find the 55th percentile, we can first find the z-score that corresponds to it. We can use a z-table or a calculator to do this, but it's important to note that some tables and calculators give z-scores for the area to the left of a given value, while others give z-scores for the area to the right of a given value. In this case, we can use a calculator that gives z-scores for the area to the left of a given value, such as the standard normal distribution calculator at stattrek.com. We can enter 0.55 as the percentile value and click "Compute" to get the z-score. We get:

z = 0.14 (rounded to two decimal places) Now we can use the formula to find the x value: x = μ + zσx = 50.2 + 0.14(3.7) x = 51.3 (rounded to one decimal place)

Therefore, the amount that represents the 55th percentile for this distribution is 51.3 ounces.

Answer:

When measuring the return on an investment, the real interest

rate accounts for inflation, while the normal interest rate does not.

Step-by-step explanation:

No, it is not possible to have more than one absolute maximum.

An absolute maximum is the largest value that a function can attain, and there can only be one such value.

To prove this, let's consider a graphical argument. Suppose that a function has two absolute maxima, as shown in the graph below.

The two absolute maxima are the points where the function reaches its highest value. However, since the function is continuous, it must also pass through all the points in between the two absolute maxima. This means that there must be a point where the function is greater than both of its absolute maxima, which is a contradiction.

Therefore, it is not possible for a function to have more than one absolute maximum.

Here is another way to think about it. The absolute maximum of a function is the value that the function approaches as the input approaches positive or negative infinity. If a function had two absolute maxima, then it would approach two different values as the input approached positive or negative infinity, which is not possible.

Therefore, we can conclude that it is not possible for a function to have more than one absolute maximum.

To evaluate the definite integral ∫[-40,811, -352] x^3 dx, we can use the power rule of integration. Applying the power rule, we increase the exponent of x by 1 and divide by the new exponent:

∫ x^3 dx = (1/4) x^4 + C,

where C is the constant of integration.

Now, we can evaluate the definite integral by substituting the upper and lower limits:

∫[-40,811, -352] x^3 dx = [(1/4) x^4] |-40,811, -352

= (1/4) (-40,811)^4 - (1/4) (-352)^4.

The percent markup based on cost is (P^(6) - 1) x 100%.

To calculate the percent markup based on cost, we need to find the difference between the selling price and the cost, divide that difference by the cost, and then express the result as a percentage.

The cost of a box of Wendy's cupcakes is P^(10). The selling price is P^(16). So the difference between the selling price and the cost is:

P^(16) - P^(10)

We can simplify this expression by factoring out P^(10):

P^(16) - P^(10) = P^(10) (P^(6) - 1)

Now we can divide the difference by the cost:

(P^(16) - P^(10)) / P^(10) = (P^(10) (P^(6) - 1)) / P^(10) = P^(6) - 1

Finally, we can express the result as a percentage by multiplying by 100:

(P^(6) - 1) x 100%

The solution that satisfies y(0) = 7 and y'(0) = 1 is:

y = 7e^(3x) - 20xe^(3x)

To verify that y₁ = e^(3x) and y₂ = xe^(3x) are solutions to the given differential equation, we need to substitute them into the equation and check if it holds true.

(a) Let's start by verifying y₁ = e^(3x):

Taking the first and second derivatives of y₁:

y₁' = 3e^(3x)

y₁'' = 9e^(3x)

Substituting these derivatives into the differential equation:

9e^(3x) - 6(3e^(3x)) + 9(e^(3x)) = 0

9e^(3x) - 18e^(3x) + 9e^(3x) = 0

0 = 0

Since the equation holds true, y₁ = e^(3x) is a solution.

Now let's verify y₂ = xe^(3x):

Taking the first and second derivatives of y₂:

y₂' = e^(3x) + 3xe^(3x)

y₂'' = 3e^(3x) + 3e^(3x) + 9xe^(3x)

Substituting these derivatives into the differential equation:

(3e^(3x) + 3e^(3x) + 9xe^(3x)) - 6(e^(3x) + 3xe^(3x)) + 9(xe^(3x)) = 0

3e^(3x) + 3e^(3x) + 9xe^(3x) - 6e^(3x) - 18xe^(3x) + 9xe^(3x) = 0

0 = 0

Since the equation holds true, y₂ = xe^(3x) is also a solution.

(b) The most general solution can be written as a linear combination of the two solutions:

y = c₁y₁ + c₂y₂

  = c₁e^(3x) + c₂xe^(3x)

(c) To find the solution that satisfies y(0) = 7 and y'(0) = 1, we substitute these initial conditions into the general solution:

y(0) = c₁e^(3(0)) + c₂(0)e^(3(0)) = c₁

Setting this equal to 7, we get c₁ = 7.

y'(0) = 3c₁e^(3(0)) + c₂(e^(3(0)) + 3(0)e^(3(0))) = 3c₁ + c₂

Setting this equal to 1, we get 3c₁ + c₂ = 1.

Substituting c₁ = 7 into the second equation, we have:

3(7) + c₂ = 1

21 + c₂ = 1

The square root of 17 is approximately 4.123. The integer closest to this approximation is 4.

To estimate the square root of 17, we can use various methods such as long division, the Babylonian method, or a calculator. In this case, the square root of 17 is approximately 4.123 when rounded to three decimal places.

To determine the integer closest to this approximation, we compare the distance between 4.123 and the two integers surrounding it, namely 4 and 5. The distance between 4.123 and 4 is 0.123, while the distance between 4.123 and 5 is 0.877. Since 0.123 is smaller than 0.877, we conclude that 4 is the integer closest to the square root of 17.

This means that 4 is the whole number that best approximates the value of the square root of 17. While 4 is not the exact square root, it is the closest integer to the true value. It's important to note that square roots of non-perfect squares, like 17, are typically irrational numbers and cannot be expressed exactly as a finite decimal or fraction.

Therefore, the particular solution to the differential equation with the initial condition y(0) = 2 is: 2cos(x) + ycos(x) + 5sin(x) = 4.

To solve the exact differential equation:

(−2sin(x)−ysin(x)+5cos(x))dx + (cos(x))dy = 0

We need to check if the equation satisfies the condition for exactness, which is:

∂(M)/∂(y) = ∂(N)/∂(x)

Where M = −2sin(x)−ysin(x)+5cos(x) and N = cos(x).

Taking the partial derivatives:

∂(M)/∂(y) = -sin(x)

∂(N)/∂(x) = -sin(x)

Since ∂(M)/∂(y) = ∂(N)/∂(x), the equation is exact.

To find the solution, we integrate M with respect to x and N with respect to y.

Integrating M with respect to x:

∫[−2sin(x)−ysin(x)+5cos(x)]dx = -2∫sin(x)dx - y∫sin(x)dx + 5∫cos(x)dx

= 2cos(x) + ycos(x) + 5sin(x) + C1

Here, C1 is the constant of integration.

Now, we differentiate the above result with respect to y to obtain the function F(x, y):

∂(F)/∂(y) = cos(x)

Comparing this with N = cos(x), we find that F(x, y) = 2cos(x) + ycos(x) + 5sin(x) + C2, where C2 is another constant of integration.

Since F(x, y) is the potential function, the general solution to the exact differential equation is:

2cos(x) + ycos(x) + 5sin(x) = C

We can use the initial condition y(0) = 2 to find the particular solution.

Substituting x = 0 and y = 2 into the equation, we get:

2cos(0) + 2cos(0) + 5sin(0) = C

2 + 2 + 0 = C

C = 4

2cos(x) + ycos(x) + 5sin(x) = 4

There can be overlapping elements that have different values assigned by \(f\) and \(g\), leading to ambiguity and violating the definition of a function.

To prove that the set \(h = f \cap g\) is a rule associated with a function, we need to show that \(h\) satisfies the necessary conditions for a function, namely that it assigns a unique element from the codomain to each element in the domain.

For \(h\) to be a function, the domain of \(h\) must be defined such that each element in the domain has a unique corresponding value in the codomain.

Let's assume that the domain of \(f\) and \(g\) is \(A\) and the codomain is \(B\). To ensure that \(h\) is a function, we need to consider the intersection of the domains of \(f\) and \(g\), denoted as \(A' = A \cap A\). The domain of \(h\) will be \(A'\), as we are only interested in the elements that are common to both \(f\) and \(g\).

Now, we can define \(h\) as a rule associated with a function:

For each element \(x\) in the domain \(A'\), \(h(x) = f(x) \cap g(x)\), where \(f(x)\) and \(g(x)\) represent the values assigned by \(f\) and \(g\) respectively.

By construction, \(h\) assigns a unique value from the codomain \(B\) to each element in the domain \(A'\), satisfying the requirement for a function.

If we were to consider the union of \(f\) and \(g\), denoted as \(f \cup g\), it would not generally be a rule associated with a function. The reason is that the union of two functions does not guarantee a unique assignment of values from the codomain for each element in the domain. There can be overlapping elements that have different values assigned by \(f\) and \(g\), leading to ambiguity and violating the definition of a function.
