To determine if the vector V3=(24, -1, 5, 0, 3) belongs to the span of vectors Vy and Vz, we need to check if V3 can be expressed as a linear combination of Vy and Vz. The answer is: False

Let's denote the vectors Vy and Vz as follows:
Vy = (R, V12, 0, 3) Vz = (V, 1, 3, 0)

To check if V3 belongs to the span of Vy and Vz, we need to see if there exist scalars a and b such that:
V3 = aVy + bVz

Now, let's try to solve for a and b by setting up the equations:
24 = aR + bV -1 = aV12 + b1 5 = a0 + b3 0 = a3 + b0 3 = a0 + b3

From the last equation, we can see that b = 1. However, if we substitute this value of b into the second equation, we get a contradiction:
-1 = aV12 + 1

Since there is no value of a that satisfies this equation, we can conclude that V3 does not belong to the span of Vy and Vz. Therefore, the answer is: False

The slope of the tangent line is: dr/dθ (θ=π/4) = -3sin(π/4) = -3/√2

To find the slope of the curve r=3+3cosθ at the points θ≠π/2, we need to first take the derivative of r with respect to θ. Using the chain rule, we get:
dr/dθ = -3sinθ
Next, we can find the slope of the tangent line at a point by evaluating this derivative at that point. For example, at θ=0, the slope of the tangent line is:
dr/dθ (θ=0) = -3sin(0) = 0

At θ=π/4, the slope of the tangent line is:

dr/dθ (θ=π/4) = -3sin(π/4) = -3/√2

We can continue to evaluate the slope of the tangent line at other points θ≠π/2. To sketch the curve along these tangents, we can draw a small section of the curve centered at each point, and then draw a straight line through that point with the corresponding slope. This will give us a rough idea of what the curve looks like along these tangents.

To find the gradient, we take the partial derivative of the function with respect to each variable (x, y, and z) separately, while keeping the other variables constant. The resulting partial derivatives form the components of the gradient vector.

To find the gradient of a function, we take the partial derivatives of the function with respect to each variable separately, while treating the other variables as constants. In this case, we have the function f(x, y, z) = (x^2 − 3y^2 + z^2)/(2x + y − 4z).

To find ∂f/∂x (the partial derivative of f with respect to x), we differentiate the function with respect to x while treating y and z as constants. This gives us (4x^2 - 3y^2 + 2z^2 + 6xy - 8xz)/(2x + y - 4z)^2.

Similarly, we find ∂f/∂y by differentiating the function with respect to y while treating x and z as constants. This yields (-6xy + 6y^2 + 8yz - 6z^2)/(2x + y - 4z)^2.

Using integration by parts, the evaluation of [tex]∫[16x(9 In 4x)]dx (1/4)x^2(In 4x) - (1/8)x^2 + C.[/tex]

To evaluate the given integral, we can use the integration by parts formula, which states that ∫(u dv) = uv - ∫(v du), where u and v are differentiable functions of x. In this case, we can choose u = 16x and dv = 9 In 4x dx. Taking the first derivative of u, we have du = 16 dx, and integrating dv gives v[tex]= (1/9)x^2(In 4x) - (1/8)x^2.[/tex]

Now, applying the integration by parts formula, we have:

In the given problem, we are asked to identify the expressions for 'u' and 'dx' in two different integrals. The first integral involves the function f(x) = (14 - 3x^2)/(-6x), while the second integral involves the function g(x) = (3 - sqrt(x))/(2x).

In the first integral, u and dx can be identified using the substitution method. We let u = 14 - 3x^2 and du = -6xdx. Rearranging these equations, we have dx = du/(-6x). Substituting these expressions into the integral, the integral becomes ∫(u/(-6x))(du/(-6x)). In the second integral, we identify w and du/dx using the substitution method as well. We let w = 3 - sqrt(x) and du/dx = 2x. Solving for dx, we get dx = du/(2x). Substituting these expressions into the integral, it becomes ∫(w/2x)(du/(2x)).

In both cases, identifying u and dx allows us to simplify the original integrals by substituting them with new variables. This technique, known as substitution, can often make the integration process easier by transforming the integral into a more manageable form.

Alessandra's statement corresponds to the alternative hypothesis (c) in a hypothesis test, suggesting a change or effect of the independent variable on the dependent variable.

The statement made by Alessandra regarding a hypothesis test suggests the use of an alternative hypothesis (c). In hypothesis testing, the alternative hypothesis represents the claim or belief that there will be a change or effect on the dependent variable due to the independent variable. It opposes the null hypothesis, which assumes no change or effect. In this case, Alessandra is proposing that there will be a difference or relationship between the independent and dependent variables.

Let's assume that the initial conditions are Y(0) = a and Y'(0) = b.

The characteristic equation of the differential equation Y'' - Y = 0 is r^2 - 1 = 0. Solving for r, we get r = ±1. Therefore, the general solution of the differential equation is Y = c1e^x + c2e^-x.

To find the values of c1 and c2, we need to use the initial conditions. We know that Y(0) = a, so we can substitute x = 0 in the general solution and get c1 + c2 = a.

We also know that Y'(0) = b. Differentiating the general solution with respect to x, we get Y' = c1e^x - c2e^-x. Substituting x = 0, we get c1 - c2 = b.

Solving these two equations simultaneously, we get c1 = (a + b)/2 and c2 = (a - b)/2.

Therefore, the solution of the second-order IVP consisting of the differential equation Y'' - Y = 0 with initial conditions Y(0) = a and Y'(0) = b is:

Y = (a + b)/2*e^x + (a - b)/2*e^-x.

The appropriate type of t-test for analyzing the relationship between the restrictiveness of gun laws and gun-crime rates in the researcher's study would be an independent samples t-test.

In this scenario, the researcher has divided the states into two groups based on the restrictiveness of gun laws: strict gun laws and lax gun laws. The goal is to compare the mean gun crime rates between these two groups. An independent samples t-test is used when comparing the means of two independent groups. In this case, the groups (states with strict gun laws and states with lax gun laws) are independent because each state falls into only one group based on its gun laws.

The independent samples t-test allows the researcher to determine whether there is a statistically significant difference in the means of the gun crime rates between the two groups. This test takes into account the sample means, sample sizes, and sample variances to calculate a t-value, which can then be compared to the critical t-value to determine statistical significance. By using this test, the researcher can assess whether the restrictiveness of gun laws is associated with differences in gun-crime rates.

The Cartesian equation of the line represented by the polar equation r = 5 + 6sin(θ) + 13cos(θ) can be expressed as y = mx + b, where m and b are constants. The formula for y in terms of x is explained below.

To find the Cartesian equation of the line, we need to convert the polar equation into Cartesian coordinates. Using the conversion formulas, we have:

x = rcos(θ) = (5 + 6sin(θ) + 13cos(θ))cos(θ) = 5cos(θ) + 6sin(θ)cos(θ) + 13cos²(θ)

y = rsin(θ) = (5 + 6sin(θ) + 13cos(θ))sin(θ) = 5sin(θ) + 6sin²(θ) + 13cos(θ)sin(θ)

Now, we can simplify the expressions for x and y:

x = 5cos(θ) + 6sin(θ)cos(θ) + 13cos²(θ)

y = 5sin(θ) + 6sin²(θ) + 13cos(θ)sin(θ)

To express y in terms of x, we can rearrange the equation by solving for sin(θ) and substituting it back into the equation:

sin(θ) = (y - 5sin(θ) - 13cos(θ)sin(θ))/6

sin(θ) = (y - 13cos(θ)sin(θ) - 5sin(θ))/6

Next, we square both sides of the equation:

sin²(θ) = (y - 13cos(θ)sin(θ) - 5sin(θ))²/36

Expanding the squared term and simplifying, we get:

36sin²(θ) = y² - 26ysin(θ) - 169cos²(θ)sin²(θ) - 10ysin(θ) + 65cos(θ)sin²(θ) + 25sin²(θ)

Now, we can use the identity sin²(θ) + cos²(θ) = 1 to simplify the equation further:

36sin²(θ) = y² - 26ysin(θ) - 169(1 - sin²(θ))sin²(θ) - 10ysin(θ) + 65cos(θ)sin²(θ) + 25sin²(θ)

36sin²(θ) = y² - 26ysin(θ) - 169sin²(θ) + 169sin⁴(θ) - 10ysin(θ) + 65cos(θ)sin²(θ) + 25sin²(θ)

Rearranging the terms and grouping the sin⁴(θ) and sin²(θ) terms, we have:

169sin⁴(θ) + (26 + 10y - 25)sin²(θ) + (26y - y²)sin(θ) + 169sin²(θ) - 36sin²(θ) - y² = 0

Simplifying the equation, we obtain:

169sin⁴(θ) + (140 - 11y)sin²(θ) + (26y - y²)sin(θ) - y² = 0

This equation represents a quartic equation in sin(θ), which can be solved using numerical methods or factoring techniques.

Once sin(θ) is determined, we can substitute it back into the equation y = 5sin(θ) + 6sin²(θ) + 13cos(θ)sin(θ) to express y in terms of x, yielding the final formula for y in terms of z.

To find the indefinite integral of -8x sin(4x + 3) dx, we can use the substitution u = 4x + 3. After performing the substitution and integrating, we obtain the antiderivative of -2/4 cos(u) du. We then substitute back u = 4x + 3 to find the final answer. Differentiating the result confirms its correctness.

Let's start by making the substitution u = 4x + 3. We can rewrite the integral as -8x sin(4x + 3) dx = -2 sin(u) du. Now we can integrate -2 sin(u) with respect to u to obtain the antiderivative. The integral of -2 sin(u) du is 2 cos(u) + C, where C is the constant of integration.

Substituting back u = 4x + 3, we have 2 cos(u) + C = 2 cos(4x + 3) + C. This expression represents the antiderivative of -8x sin(4x + 3) dx.

To verify the result, we can differentiate 2 cos(4x + 3) + C with respect to x. Taking the derivative gives -8 sin(4x + 3), which is the original function. Thus, the obtained antiderivative is correct.

The arc length of the curve r = 2cos(6θ) on the interval [0, π/6] cannot be expressed exactly using elementary functions. It can only be approximated numerically.

To find the arc length of the curve given by the polar equation r = 2cos(6θ) on the interval [0, π/6], we can use the formula for arc length in polar coordinates:

L = ∫[a, b] √(r^2 + (dr/dθ)^2) dθ

In this case, we have r = 2cos(6θ) and dr/dθ = -12sin(6θ).

Substituting these values into the arc length formula, we get:

L = ∫[0, π/6] √((2cos(6θ))^2 + (-12sin(6θ))^2) dθ

 = ∫[0, π/6] √(4cos^2(6θ) + 144sin^2(6θ)) dθ

 = ∫[0, π/6] √(4cos^2(6θ) + 144(1 - cos^2(6θ))) dθ  [Using the identity sin^2(x) + cos^2(x) = 1]

 = ∫[0, π/6] √(4cos^2(6θ) + 144 - 144cos^2(6θ)) dθ

 = ∫[0, π/6] √(144 - 140cos^2(6θ)) dθ

 = ∫[0, π/6] √(4(36 - 35cos^2(6θ))) dθ

 = ∫[0, π/6] 2√(36 - 35cos^2(6θ)) dθ

To evaluate this integral, we can make a substitution: u = 6θ. Then, du = 6dθ and the limits of integration become [0, π/6] → [0, π/3].

The integral becomes:

L = 2∫[0, π/3] √(36 - 35cos^2(u)) du

At this point, we can recognize that the integrand is in the form √(a^2 - b^2cos^2(u)), which is a known integral called the elliptic integral of the second kind. Unfortunately, there is no simple closed-form expression for this integral.

To solve the problem, we'll break it down into steps:Step 1: Understand the problem. We have a television camera located 2000 feet away from a space rocket launching pad.

We need to determine the angle of elevation from the camera to the rocket. Step 2: Visualize the situation. Imagine a right triangle where the launching pad is the base, the line connecting the camera to the launching pad is the hypotenuse, and the vertical line from the camera to the rocket is the height or opposite side of the triangle. The angle of elevation is the angle between the hypotenuse and the height. Step 3: Identify known values. The distance between the camera and the launching pad is 2000 feet (the base of the triangle).We want to find the angle of elevation (the angle between the hypotenuse and the height).

Step 4: Apply trigonometry. Using trigonometric ratios, we can find the angle of elevation. In this case, we'll use the tangent function. Tangent of an angle = opposite side / adjacent side.

In our case:   Tangent of the angle of elevation = height / base. Step 5: Calculate the height. Let's assign variables to the unknowns: Let h be the height (opposite side). Let θ be the angle of elevation. According to the given information, the base is 2000 feet. We don't know the height, so let's solve for it. Tangent θ = h / 2000. Multiply both sides by 2000:2000 * tangent θ = h.  Step 6: Evaluate the angle of elevation. To find the angle of elevation, we'll need to use inverse tangent (arctan or tan^(-1)). θ = arctan(h / 2000).  Step 7: Substitute values and calculate. If you have a specific value for h or any additional information, substitute it into the equation and calculate the angle of elevation using a scientific calculator or trigonometric table.

What is integration?

Integration is a fundamental concept in calculus that involves finding the integral of a function.

To evaluate the integral ∫ y*sin(x) dx, where y > 0, we can follow these steps:

Integrate the function y*sin(x) with respect to x. The integral of sin(x) is -cos(x), so we have:

∫ ysin(x) dx = -ycos(x) + C,

where C is the constant of integration.

Apply the limits of integration if they are provided in the problem. If not, leave the result in indefinite form.

If there are specific limits of integration given, let's say from a to b, then the definite integral becomes:

∫[a to b] ysin(x) dx = [-ycos(x)] evaluated from x = a to x = b

∑[n=-N to N] sin(4.5n) = ∑[k=-2N to 2N] sin(4.5kπ/9),

where k = n/2. Now, we have a geometric series with a common ratio of sin(4.5π/9).

Using the formula for the sum of a geometric series, the sum becomes:

∑[k=-2N to 2N] sin(4.5kπ/9) = (sin(4.5(-2N)π/9) - sin(4.5(2N+1)π/9))/(1 - sin(4.5π/9)).

Similar to the previous sum, we can rewrite the sum as follows:

∑[n=-N to N] cos(3n) = ∑[k=-2N to 2N] cos(3kπ/3) = ∑[k=-2N to 2N] cos(kπ) = 2N + 1.

Now, we can evaluate the overall sum:

∑[n=-N to N] (sin(4.5n) + cos(3n)) = ∑[n=-N to N] sin(4.5n) + ∑[n=-N to N] cos(3n)

= (sin(4.5(-2N)π/9) - sin(4.5(2N+1)π/9))/(1 - sin(4.5π/9)) + (2N + 1).

In this solution, we are given the sum ∑[n=-N to N] (sin(4.5n) + cos(3n)) and we want to evaluate it.

We break down the sum into two separate sums: ∑[n=-N to N] sin(4.5n) and ∑[n=-N to N] cos(3n).

For the sin(4.5n) sum, we use the formula for the sum of a geometric series, taking into account the periodicity of sin(4.5n). We simplify the sum using the geometric series formula and obtain a closed form expression.

For the cos(3n) sum, we observe that it simplifies to (2N + 1) since cos(3n) has a periodicity of 2π/3.

Finally, we combine the two sums to obtain the overall sum.

Therefore, the main answer is the expression: (sin(4.5(-2N)π/9) - sin(4.5(2N+1)π/9))/(1 - sin(4.5π/9)) + (2N + 1).

False. Knowing the angular velocity (ω) and angular acceleration (α) of a body does not allow for the determination of the velocity and acceleration of any point on the body.

While the angular velocity and angular acceleration provide information about the rotational motion of a body, they alone are insufficient to determine the velocity and acceleration of any specific point on the body. To determine the velocity and acceleration of a point on a body, additional information such as the distance of the point from the axis of rotation and the direction of motion is required. This information can be obtained through techniques like vector analysis or kinematic equations, taking into account the specific geometry and motion of the body. Therefore, the knowledge of angular velocity and angular acceleration alone does not provide sufficient information to determine the velocity and acceleration of any arbitrary point on the body.

The correct answer is (a) f(9)=5. Option (d) says that f(9,5)=14, which is also false, as the output value for input values 9 and 5 is not 14.

In function notation, we use the letter "f" followed by the input value in parentheses to represent the output value. Looking at the table, we can see that when the input value is 9, the output value is 5. So, the correct function notation is f(9)=5.

To fully understand the function represented by the table, we need to look at each row and column. In the first column, we have the input values ranging from 2 to 9. In the second column, we have the corresponding output values. For example, when the input value is 2, the output value is 7. To check if the function is consistent, we can look at the last row. The last row shows the output values for two different input values: 5 and 9. When the input values are 5 and 9, the output value is 9 and 5, respectively. This means that the function is not consistent, as the output values are not the same for different input values. Now, let's look at the options given in the question. Option (a) says that f(9)=5, which is true based on the table. Option (b) says that f(5)=9, which is false, as the output value for input value 5 is 7, not 9. Option (c) says that f(5,9)=14, which is also false, as there is no input value that corresponds to an output value of 14.

We will use the method of undetermined coefficients to solve the given differential equation: y' + 8y = e^(-8t)cos(t), with the initial condition y(0) = 9. Therefore, the complete solution to the given differential equation is: y(t) = y_c(t) + y_p(t) = (9 + 1/65)*e^(-8t) + (-1/65)*e^(-8t)cos(t) + (-8/65)*e^(-8t)sin(t)

In the method of undetermined coefficients, we assume a particular solution in the form of y_p(t) = Ae^(-8t)cos(t) + Be^(-8t)sin(t), where A and B are constants to be determined.

We take the derivatives of y_p(t):

y_p'(t) = -8Ae^(-8t)cos(t) - Ae^(-8t)sin(t) - 8Be^(-8t)sin(t) + Be^(-8t)cos(t)

Plugging y_p(t) and y_p'(t) into the differential equation, we have:

(-8Ae^(-8t)cos(t) - Ae^(-8t)sin(t) - 8Be^(-8t)sin(t) + Be^(-8t)cos(t)) + 8*(Ae^(-8t)cos(t) + Be^(-8t)sin(t)) = e^(-8t)cos(t)

Simplifying and matching the coefficients of the exponential terms and trigonometric terms on both sides, we obtain the following equations:

-8A + B = 1

-A - 8B = 0

Solving these equations, we find A = -1/65 and B = -8/65.

Therefore, the particular solution is y_p(t) = (-1/65)*e^(-8t)cos(t) + (-8/65)*e^(-8t)sin(t).

To find the complete solution, we add the complementary solution, which is the solution to the homogeneous equation y' + 8y = 0. The homogeneous solution is y_c(t) = C*e^(-8t), where C is a constant.

Using the initial condition y(0) = 9, we substitute t = 0 into the complete solution and solve for C:

9 = y_c(0) + y_p(0) = C + (-1/65)*1 + (-8/65)*0

C = 9 + 1/65

Therefore, the complete solution to the given differential equation is:

y(t) = y_c(t) + y_p(t) = (9 + 1/65)*e^(-8t) + (-1/65)*e^(-8t)cos(t) + (-8/65)*e^(-8t)sin(t).

The root test for the series ∑ (n / (3n + 9)^(4/n)) is inconclusive, as the limit evaluates to 1. Therefore, we cannot determine whether the series converges or diverges using the root test alone.

To determine whether the series ∑ (n / (3n + 9)^(4/n)) converges or diverges using the root test, we need to evaluate the limit:

lim (n → ∞) |n / (3n + 9)^(4/n)|.

Using the properties of limits, we can rewrite the expression inside the absolute value as:

lim (n → ∞) (n^(1/n)) / (3 + 9/n)^(4/n).

Since the limit involves both exponentials and fractions, it is not immediately apparent whether it converges to a specific value or not. To simplify the expression, we can take the natural logarithm of the limit and apply L'Hôpital's rule:

ln lim (n → ∞) (n^(1/n)) / (3 + 9/n)^(4/n).

Taking the natural logarithm allows us to convert the exponentiation into multiplication, which simplifies the expression. Applying L'Hôpital's rule, we differentiate the numerator and denominator with respect to n:

ln lim (n → ∞) [(1/n^2) * n^(1/n)] / [(4/n^2) * (3 + 9/n)^(4/n - 1)].

Simplifying further, we obtain:

ln lim (n → ∞) [n^(1/n-2) / (3 + 9/n)^(4/n - 1)].

Now, we can evaluate the limit as n approaches infinity. By analyzing the exponents in the numerator and denominator, we see that as n becomes larger, the terms n^(1/n-2) and (3 + 9/n)^(4/n - 1) both tend to 1. Therefore, the limit simplifies to:

ln (1/1) = 0.

Since the natural logarithm of the limit is 0, we can conclude that the original limit is equal to 1.

According to the root test, if the limit is less than 1, the series converges; if the limit is greater than 1, the series diverges; and if the limit is equal to 1, the test is inconclusive.

In this case, the limit is equal to 1, which means that the root test is inconclusive. We cannot determine whether the series converges or diverges based on the root test alone. Additional tests or methods would be required to reach a conclusion.

The sine of π/8 is (√2 - √6)/4 and the value of the expression |V × (U + V)| is equal to √901.

To find the values based on the given information, let's break down the problem:

1. Sin(θ):

Since θ is given as 8 (0 ≤ θ ≤ π), we can directly evaluate sin(θ). However, it seems there might be a typo in the question because the value of θ is given as 8, which is not within the specified range of 0 to π.

Assuming the value is actually π/8, we can proceed.

The sine of π/8 is (√2 - √6)/4.

2. V - V:

The expression V - V represents the subtraction of vector V from itself. Any vector subtracted from itself will result in the zero vector.

Therefore, V - V = 0.

3. |V × (U + V)|:

To calculate the magnitude of the cross product V × (U + V), we need to find the cross product first. The cross product of two vectors is given by the determinant of a matrix.

Using the given values, we have:

V × (U + V) = 16(8i + 3j + 3k) × (i + 2j + 3k)

           = 16(24i - 15j + 10k)

To find the magnitude, we calculate the square root of the sum of the squares of the components:

|V × (U + V)| = [tex]\sqrt{(24)^2 + (-15)^2 + (10)^2[/tex]

             = [tex]\sqrt{576 + 225 + 100[/tex]

             = √901

Please note that the answer for sin(θ) assumes the value of θ to be π/8, as the given value of 8 does not fall within the specified range.

A bijective rational function with degree 1 on both the numerator and denominator can be defined as f(x) = (ax + b) / (cx + d), where a, b, c, and d are non-zero constants.

Let's consider the function f(x) = (ax + b) / (cx + d), where a, b, c, and d are non-zero constants. To ensure bijectivity, we need to carefully define the domain and range. The domain can be defined as the set of all real numbers excluding the value x = -d/c (to avoid division by zero). The range can be defined as the set of all real numbers excluding the value y = -b/a (to avoid division by zero).

To prove that the function is bijective, we need to show that it is both injective (one-to-one) and surjective (onto). For injectivity, we assume that f(x₁) = f(x₂) and show that x₁ = x₂. By equating the expressions (ax₁ + b) / (cx₁ + d) and (ax₂ + b) / (cx₂ + d), we can cross-multiply and simplify to obtain a linear equation in x₁ and x₂. By solving this equation, we can prove that x₁ = x₂, thus establishing injectivity.

The difference quotient of the function f(x) = 7/(9x + 9) is 0.

To find the difference quotient of the function f(x) = 7/(9x + 9), we can use the formula:

[f(x + h) - f(x)] / h

First, let's substitute f(x + h) and f(x) into the formula:

[f(x + h) - f(x)] / h = [7/(9(x + h) + 9) - 7/(9x + 9)] / h

Next, let's find a common denominator for the fractions:

[f(x + h) - f(x)] / h = [7(9x + 9) - 7(9(x + h) + 9)] / [h(9(x + h) + 9)(9x + 9)]

Simplifying further:

[f(x + h) - f(x)] / h = [63x + 63 + 63h - 63x - 63h - 63] / [h(9(x + h) + 9)(9x + 9)]

The terms 63h and -63h cancel each other out:

[f(x + h) - f(x)] / h = [63x + 63 - 63] / [h(9(x + h) + 9)(9x + 9)]

[f(x + h) - f(x)] / h = 0 / [h(9(x + h) + 9)(9x + 9)]

Since the numerator is 0, the entire difference quotient simplifies to 0.

Therefore, the difference quotient for the given function is 0. Please note that the denominator h(9(x + h) + 9)(9x + 9) should not be equal to 0 for the difference quotient to be defined.

Integrating (x + y + x) with respect to x gives: (x^2/2 + xy + x^2/2) + C1

Next, we integrate (x^2/2 + xy + x^2/2) + C1 with respect to z:

(∫((x^2/2 + xy + x^2/2) + C1) dz)

Integrating each term separately: ((x^2/2 + xy + x^2/2)z + C1z) + C2

Simplifying, we get:

y' = 1/(16y)

Integrating both sides, we get:

∫(1/y) dy = ∫(1/16) dx

ln|y| = x/16 + C

Solving for y, we get:

y = ± e^(x/16 + C)

Simplifying, we get:

y = ± Ae^(x/16)

where A = e^C

To graph the particular solutions for different initial conditions, we can simply plot multiple functions of the form:

y = ± Ae^(x/16)

For example, if we have initial condition y(0) = 1, then we can solve for

1 = ± Ae^(0/16)

1 = ± A

A = ± 1

So, the particular solution for this initial condition is:

y = e^(x/16)

Similarly, for initial condition y(0) = -1, the particular solution is:

y = -e^(x/16)

We can plot these two particular solutions on the same graph to compare them: [Graph of y = e^(x/16) and y = -e^(x/16) on the same axes]

We can see that both solutions are exponential curves with different signs, and they intersect at x = 0. This is because they correspond to opposite initial conditions (positive and negative, respectively) but both satisfy the same differential equation.
