The range of the function f(x) = ½ sin(2/3x + π/6) + 5 is the interval (4.5, 5.5).

The given function is a sinusoidal function of the form f(x) = a sin(bx + c) + d, where a, b, c, and d are constants. In this case, a = 1/2, b = 2/3, c = π/6, and d = 5.

The sine function has a range between -1 and 1. When we multiply the sine function by 1/2, it stretches the graph vertically, limiting the range between -1/2 and 1/2. Adding 5 to the function shifts the graph upwards by 5 units.

Therefore, the range of f(x) will be the values that the function can take on. The lowest value it can reach is -1/2 + 5 = 4.5, and the highest value it can reach is 1/2 + 5 = 5.5. Hence, the range of the function f(x) is the interval (4.5, 5.5).

The correct answer is b. Characteristic equation. the equation formed by equating the denominator of a transfer function to zero is known as the characteristic equation.

In control systems theory, the characteristic equation is formed by equating the denominator of a transfer function to zero. It plays a crucial role in the analysis and design of control systems.

The transfer function of a control system is represented as the ratio of the Laplace transform of the output to the Laplace transform of the input. The denominator of the transfer function represents the characteristic equation, which is obtained by setting the denominator polynomial equal to zero.

The characteristic equation is an algebraic equation that relates the input, output, and system dynamics. By solving the characteristic equation, we can determine the system's poles, which are the values of the complex variable(s) that make the denominator zero. The poles of the system are crucial in understanding the system's stability and behavior.

The characteristic equation helps in determining the stability of a control system. If all the poles of the characteristic equation have negative real parts, the system is stable. On the other hand, if any pole has a positive real part or lies on the imaginary axis, the system is unstable or marginally stable.

Moreover, the characteristic equation is used to calculate important system properties such as the natural frequency, damping ratio, and transient response. These properties provide insights into the system's performance and behavior.

In summary, it plays a fundamental role in control systems analysis and design, allowing us to determine system stability, transient response, and other important properties.

The rotated planter box is a new quadrilateral with vertices [tex]\(Q'(2, 4)\), \(R'(2, -3)\), \(S'(-4, -3)\)[/tex], and [tex]\(T'(-4, 4)\)[/tex]. The planter box described is a quadrilateral with vertices [tex]\(Q(-2,-1)\)[/tex], [tex]\(R(5,-1)\), \(S(5,5)\)[/tex], and [tex]\(T(-2,3)\)[/tex].

When rotated [tex]\(90^\circ\)[/tex] in a clockwise direction about its centroid, the resulting shape will be a new quadrilateral with different vertex coordinates.

To find the centroid of the original quadrilateral, we calculate the average of the x-coordinates and the average of the y-coordinates of its vertices. The x-coordinate of the centroid is [tex]\((-2+5+5-2)/4 = 1.5\)[/tex], and the y-coordinate is [tex]\((-1-1+5+3)/4 = 1.5\)[/tex]. Therefore, the centroid is located at [tex]\(C(1.5, 1.5)\)[/tex].

Next, we rotate each vertex of the original quadrilateral [tex]\(90^\circ\)[/tex] in a clockwise direction around the centroid. The formula for a [tex]\(90^\circ\)[/tex] clockwise rotation is [tex]\((x_ c + y - y_ c, y_ c - x + x_ c)\)[/tex], where \((x, y)\) represents the coordinates of a vertex and [tex]\((x_ c, y_ c)\)[/tex] represents the coordinates of the centroid.

Applying the rotation formula to each vertex, we get the new coordinates for the rotated quadrilateral:

[tex]\(Q' = (1.5 - (-1) - 1.5, 1.5 - (-2) + 1.5) = (2, 4)\)[/tex]

[tex]\(R' = (1.5 - (-1) - 1.5, 1.5 - (5) + 1.5) = (2, -3)\)[/tex]

[tex]\(S' = (1.5 - (5) - 1.5, 1.5 - (5) + 1.5) = (-4, -3)\)[/tex]

[tex]\(T' = (1.5 - (-2) - 1.5, 1.5 - (3) + 1.5) = (-4, 4)\)[/tex]

Therefore, the rotated planter box is a new quadrilateral with vertices [tex]\(Q'(2, 4)\), \(R'(2, -3)\), \(S'(-4, -3)\)[/tex], and [tex]\(T'(-4, 4)\)[/tex].

The derivative y' using implicit differentiation for the equation x^2 - 4xy + y^2 = 4 is given by:y' = (4y - 2x) / (2y - 4x)

To find y' using implicit differentiation for the equation x^2 - 4xy + y^2 = 4, we differentiate both sides of the equation with respect to x.

Differentiating the left side of the equation requires the application of the chain rule.

Differentiating x^2 with respect to x gives 2x.

Differentiating -4xy with respect to x gives -4y - 4x(dy/dx), using the product rule.

Differentiating y^2 with respect to x gives 2y(dy/dx), again using the chain rule.

Therefore, the derivative of the left side of the equation is 2x - 4y - 4x(dy/dx) + 2y(dy/dx).

Differentiating the right side of the equation with respect to x gives 0, since 4 is a constant.

Now, we can rewrite the equation with the derivatives:

2x - 4y - 4x(dy/dx) + 2y(dy/dx) = 0

Next, we can rearrange the equation to solve for dy/dx:

-4x(dy/dx) + 2y(dy/dx) = 4y - 2x

Factor out dy/dx:

(2y - 4x)(dy/dx) = 4y - 2x

Divide both sides by (2y - 4x):

dy/dx = (4y - 2x) / (2y - 4x)

Hence, the derivative y' using implicit differentiation for the equation x^2 - 4xy + y^2 = 4 is given by:

y' = (4y - 2x) / (2y - 4x)

By applying the quotient rule and simplifying the resulting expression, the derivative of y with respect to x,  y′(2) = 213/169.

To calculate y′(2), the derivative of the function y with respect to x at x = 2, we can use the quotient rule and evaluate the expression using the given function.The given function is y = (x + 3)(x^2 + 2x + 5)/(3x^2 + 1).

To find y′(2), we need to calculate the derivative of y with respect to x and then evaluate it at x = 2.

Using the quotient rule, the derivative of y with respect to x is given by:

y′ = [(3x^2 + 1)(2x^2 + 4x + 5) - (x + 3)(6x)] / (3x^2 + 1)^2.

Simplifying the numerator, we have:

y′ = (6x^4 + 12x^3 + 15x^2 + 2x^2 + 4x + 5 - 6x^2 - 18x) / (3x^2 + 1)^2.

Further simplifying, we get:

y′ = (6x^4 + 12x^3 + 15x^2 + 2x^2 + 4x + 5 - 6x^2 - 18x) / (3x^2 + 1)^2.

= (6x^4 + 12x^3 + 11x^2 - 14x + 5) / (3x^2 + 1)^2.

Now, to find y′(2), we substitute x = 2 into the derivative expression:

y′(2) = (6(2)^4 + 12(2)^3 + 11(2)^2 - 14(2) + 5) / (3(2)^2 + 1)^2.

= (6(16) + 12(8) + 11(4) - 14(2) + 5) / (3(4) + 1)^2.

= (96 + 96 + 44 - 28 + 5) / (12 + 1)^2.

Both Pedro and Juan are currently 0 years old, which does not make sense in the context of the problem.

Let's assume Pedro's current age is P and Juan's current age is J.

According to the given information, Pedro is as old as Juan was when Juan is twice as old as Pedro was. Mathematically, this can be expressed as:

P = J - (J - P) * 2

Simplifying the equation, we get:

P = J - 2J + 2P

3J - P = 0   ...(Equation 1)

Furthermore, it is given that when Pedro is as old as Juan is now, the difference between their ages is 6 years. Mathematically, this can be expressed as:

(P + 6) - J = 6

Simplifying the equation, we get:

P - J = 0   ...(Equation 2)

To find their ages now, we need to solve the system of equations (Equation 1 and Equation 2) simultaneously.

Solving Equation 1 and Equation 2, we find that P = J = 0.

The appropriate reference triangle, consider a right triangle with one angle θ and sides x, √(10), and √(10 - x²).

To evaluate the indefinite integral ∫ √(10 - x²) dx, we can use a trigonometric substitution. Let's make the substitution x = √(10)sinθ, which will help us simplify the integrand.

First, let's find dx in terms of dθ:

dx = √(10)cosθ dθ

Substituting x = √(10)sinθ and dx = √(10)cosθ dθ into the integral, we get:

∫ √(10 - x²) dx = ∫ √(10 - (√(10)sinθ)²) (√(10)cosθ) dθ

= ∫ √(10 - 10sin²θ) √(10)cosθ dθ

= ∫ √(10cos²θ) √(10)cosθ dθ

= ∫ √(10)cosθ √(10cos²θ) dθ

= 10 ∫ cos²θ dθ

Using the identity cos²θ = (1 + cos(2θ))/2, we can rewrite the integral as:

10 ∫ (1 + cos(2θ))/2 dθ

= 10/2 ∫ (1 + cos(2θ)) dθ

= 5 ∫ (1 + cos(2θ)) dθ

Integrating each term separately:

= 5 ∫ dθ + 5 ∫ cos(2θ) dθ

= 5θ + 5 (1/2) sin(2θ) + C

Finally, substituting back θ = arcsin(x/√10):

= 5arcsin(x/√10) + 5/2 sin(2arcsin(x/√10)) + C

So, the indefinite integral of √(10 - x²) dx is:

∫ √(10 - x²) dx = 5arcsin(x/√10) + 5/2 sin(2arcsin(x/√10)) + C

The length of the curve defined by the polar equation \(r = 4\) over the interval \(0 \leq \theta \leq 2\pi\) is \(8\pi\).

To find the length of the curve defined by the polar equation \(r = 4\) over the interval \(0 \leq \theta \leq 2\pi\), we can use the arc length formula for polar curves.

The arc length formula for a polar curve is given by:

\[L = \int_{\theta_1}^{\theta_2} \sqrt{r^2 + \left(\frac{dr}{d\theta}\right)^2} \, d\theta\]

In this case, the polar equation \(r = 4\) is a circle with a constant radius of 4. Since the radius is constant, the derivative of \(r\) with respect to \(\theta\) is zero (\(\frac{dr}{d\theta} = 0\)). Therefore, the arc length formula simplifies to:

\[L = \int_{\theta_1}^{\theta_2} \sqrt{r^2} \, d\theta\]

Substituting the given values, we have:

\[L = \int_{0}^{2\pi} \sqrt{4^2} \, d\theta\]

Simplifying further, we get:

\[L = \int_{0}^{2\pi} 4 \, d\theta\]

Integrating, we have:

\[L = 4\theta \bigg|_{0}^{2\pi}\]

Evaluating at the limits, we get:

\[L = 4(2\pi - 0)\]

\[L = 8\pi\]

The length of the curve is \(8\pi\) units.

To find the relative maximum and minimum values of f(x,y) = x^2 + y^2 + 16x - 14y, we first find the critical points by setting the partial derivatives equal to zero:

fx = 2x + 16 = 0

f y = 2y - 14 = 0

Solving for x and y, we get (x,y) = (-8,7).

Next, we use the second partial derivative test to classify the critical point (-8,7) as a relative maximum, relative minimum, or saddle point.

f x x = 2, f yy = 2, f xy = 0

D = f x x × f y y - f xy^2 = 4 > 0, which means (-8,7) is a critical point.

f x x = 2 > 0, so f has a local minimum at (-8,7).

The arc length of the curve defined by the vector-valued function r(t) = ⟨cos³(At)⋅sin³(At)⟩, where 0 ≤ t ≤ π/(2A), can be found using the formula for arc length. The result is given by L = ∫√(r'(t)⋅r'(t)) dt, where r'(t) is the derivative of r(t) with respect to t.

To find the arc length of the curve, we start by calculating the derivative of r(t). Let's denote the derivative as r'(t). Taking the derivative of each component of r(t), we have r'(t) = ⟨-3Acos²(At)sin³(At), 3Asin²(At)cos³(At)⟩.

Next, we need to compute the dot product of r'(t) with itself, which is r'(t)⋅r'(t). Simplifying the dot product expression, we get r'(t)⋅r'(t) = (-3Acos²(At)sin³(At))^2 + (3Asin²(At)cos³(At))^2. Expanding and combining terms, we have r'(t)⋅r'(t) = 9A²cos⁴(At)sin⁶(At) + 9A²sin⁴(At)cos⁶(At).

Now, we can integrate the square root of r'(t)⋅r'(t) over the given interval 0 ≤ t ≤ π/(2A). The integral is represented as L = ∫√(r'(t)⋅r'(t)) dt. Substituting the expression for r'(t)⋅r'(t), we have L = ∫√(9A²cos⁴(At)sin⁶(At) + 9A²sin⁴(At)cos⁶(At)) dt.

To minimize the function \(f(x, y, z) = x^2 + y^2 + z^2\) under the constraint \(x + 2y - 3z = 5\), we can use the method of Lagrange multipliers. This method allows us to optimize a function subject to constraints.

The Lagrangian function combines the objective function \(f(x, y, z)\) and the constraint function \(g(x, y, z)\) using a Lagrange multiplier \(\lambda\) to introduce the constraint.

To find the minimum, we need to solve the following system of equations:

\(\frac{\partial\mathcal{L}}{\partial x} = \frac{\partial\mathcal{L}}{\partial y} = \frac{\partial\mathcal{L}}{\partial z} = \frac{\partial\mathcal{L}}{\partial \lambda} = 0\).

Taking the partial derivatives, we have:

\(\frac{\partial\mathcal{L}}{\partial x} = 2x - \lambda = 0\),

\(\frac{\partial\mathcal{L}}{\partial y} = 2y - 2\lambda = 0\),

\(\frac{\partial\mathcal{L}}{\partial z} = 2z + 3\lambda = 0\),

\(\frac{\partial\mathcal{L}}{\partial \lambda} = -(x + 2y - 3z - 5) = 0\).

From the first equation, we have \(2x = \lambda\), which gives us \(x = \frac{\lambda}{2}\).

From the second equation, we have \(2y = 2\lambda\), which gives us \(y = \lambda\).

From the third equation, we have \(2z = -3\lambda\), which gives us \(z = -\frac{3\lambda}{2}\).

Substituting these values into the constraint equation, we have:

\(\frac{\lambda}{2} + 2\lambda - 3\left(-\frac{3\lambda}{2}\right) = 5\).

Simplifying, we get:

\(\frac{\lambda}{2} + 2\lambda + \frac{9\lambda}{2} = 5\).

Combining like terms, we have:

\(6\lambda = 10\).

Thus, \(\lambda = \frac{5}{3}\).

Substituting this value back into the expressions for \(x\), \(y\), and \(z\), we get:

\(x = \frac{\lambda}{2} = \frac{5}{6}\),

\(y = \lambda = \frac{5}{3}\),

\(z = -\frac{3\lambda}{2} = -\frac{5}{2}\).

Therefore, the point that minimizes the function \(f(x, y, z)\) under the constraint \(x + 2y - 3z = 5\) is \((x, y, z) = \left(\frac{5}{6}, \frac{5}{3}, -\frac{5}{2}\right)\).

Sub

stituting these values into the objective function \(f(x, y, z)\), we find the minimum value:

\(f\left(\frac{5}{6}, \frac{5}{3}, -\frac{5}{2}\right) = \left(\frac{5}{6}\right)^2 + \left(\frac{5}{3}\right)^2 + \left(-\frac{5}{2}\right)^2 = \frac{25}{36} + \frac{25}{9} + \frac{25}{4} = \frac{225}{36} = \frac{25}{4}\).

Therefore, the minimum value of \(f(x, y, z)\) under the constraint \(x + 2y - 3z = 5\) is \(\frac{25}{4}\).

The estimated winners' prize in 2040, assuming the same rate of increase per year, is approximately $54,680,580,063,400.

The initial value is $150, and the final value is $1,163,000. The number of years between 1895 and 2007 is 2007 - 1895 = 112 years.

Using the formula for percentage increase:
Percentage Increase = [(Final Value - Initial Value) / Initial Value] * 100
= [(1,163,000 - 150) / 150] * 100
= (1,162,850 / 150) * 100
= 775,233.33%

Therefore, the winners' check increased by approximately 775,233.33% over the period from 1895 to 2007.

To estimate the winners' prize in 2040, we assume the same rate of increase per year. We can use the formula:
Future Value = Initial Value * (1 + Percentage Increase)^Number of Years

Since the initial value is $1,163,000, the percentage increase per year is 775,233.33%, and the number of years is 2040 - 2007 = 33 years, we can calculate the future value:

Calculating this expression:
Future Value = 1,163,000 * (1 + 775,233.33%)^33

Using a calculator or computer software, we can evaluate this expression to find the future value. Here's the result:

Future Value ≈ $1,163,000 * (1 + 77.523333)^33 ≈ $1,163,000 * 47,051,979.42 ≈ $54,680,580,063,400

Therefore, based on the assumed rate of increase per year, the estimated winners' prize in 2040 would be approximately $54,680,580,063,400.

Subcase (a) can be used when the power of tangent is odd and the power of secant is even, while subcase (b) can be used when the power of tangent is odd and the power of secant is odd.

To determine the conditions under which the subcases (a) and (b) can be used in integrating the given functions, we analyze the powers of tangent (tan) and secant (sec) involved. For subcase (a), the condition is that the power of tangent should be odd and the power of secant should be even. In subcase (b), the condition is that the power of tangent should be odd and the power of secant should be odd.

(a) Subcase (a) can be used to integrate the function ∫tan^8tsec^6(8t) dt when the power of tangent is odd and the power of secant is even. In this case, the integral can be rewritten as ∫tan^8tsec^2(8t)sec^4(8t) dt. The power of tangent (8t) is even, which satisfies the condition. The power of secant (8t) is 2, which is even as well. Therefore, subcase (a) can be applied in this scenario.

(b) Subcase (b) can be used to integrate the function ∫tan^5(x)sec^2(x) dx when the power of tangent is odd and the power of secant is odd. In this case, the integral can be written as ∫tan^4(x)tan(x)sec^2(x) dx. The power of tangent (x) is odd, satisfying the condition. However, the power of secant (x) is 2, which is even. Therefore, subcase (b) cannot be applied to this integral.

Ryan Neal has a loss of approximately $1,826. To calculate Ryan Neal's gain or loss, we need to consider the cost of buying the shares, the commission fees for buying and selling, and the selling price of the shares.

1. Cost of buying the shares:

Ryan bought 1,900 shares of Ford at $15.87 per share, so the total cost of buying the shares is:

Cost = Number of shares * Price per share = 1,900 * $15.87 = $30,153

2. Commission fees for buying:

The commission fee for buying is 19% of the purchase price, which is:

Commission fee for buying = 19% * $30,153 = $5,729.07

3. Selling price of the shares:

Ryan sells the shares for $20.18 per share, so the total selling price is:

Selling price = Number of shares * Price per share = 1,900 * $20.18 = $38,342

4. Commission fees for selling:

The commission fee for selling is also 19% of the selling price, which is:

Commission fee for selling = 19% * $38,342 = $7,285.98

Now, let's calculate the gain or loss:

Gain or Loss = Selling price - Cost - Commission fees for buying - Commission fees for selling

Gain or Loss = $38,342 - $30,153 - $5,729.07 - $7,285.98

Calculating the value, we have:

Gain or Loss ≈ $38,342 - $30,153 - $5,729 - $7,286

Gain or Loss ≈ $-1,826

Therefore, Ryan Neal has a loss of approximately $1,826.

Given that the demand for a particular item is given by the function D(x)=1,550−3x2 and the equilibrium price of a unit is $350. We need to find the consumer's surplus.We know that the consumer's surplus is given by the difference between the maximum price a consumer is willing to pay for a good or service and the actual price they pay for it.

It can be computed using the following formula:CS = ∫(a to b) [D(x)-P(x)] dxWhere,CS = consumer's surplusD(x) = demand functionP(x) = price functiona and b are the limits of integrationIn this case, the equilibrium price of a unit is $350 and we need to find the consumer's surplus.Substituting the values in the above formula, we getCS = ∫(0 to Q) [1550 - 3x² - 350] dx (since the equilibrium price of a unit is $350)CS = ∫(0 to Q) [1200 - 3x²] dx.

Now, we need to find the value of Q. Equilibrium occurs at the point where quantity demanded equals quantity supplied. At the equilibrium price of $350, the quantity demanded is given by:D(x) = 1550 - 3x² = 1550 - 3(350)² = 1550 - 367500 = -365950This negative value is meaningless and indicates that the given equilibrium price of $350 does not result in any positive quantity demanded. Thus, we can conclude that this problem is defective and the consumer's surplus does not exist.

p→q (If it rains tomorrow, then I will give you a ride home tomorrow)

True

q→p (If I give you a ride home tomorrow, then it will rain tomorrow)

False

p∧q (It rains tomorrow and I give you a ride home tomorrow)

True

p∨q (It either rains tomorrow or I give you a ride home tomorrow)

True

The first statement

p→q is true because it states that if it rains tomorrow, then I will give you a ride home tomorrow. This means that the occurrence of rain implies that I will provide a ride. If it does not rain, the statement does not make any specific claim about whether I will give a ride.

The second statement

q→p is false because it suggests that if I give you a ride home tomorrow, then it will rain tomorrow. There is no logical connection between providing a ride and the occurrence of rain, so this statement is incorrect.

The third statement

p∧q is true because it expresses that both events happen simultaneously. It states that it rains tomorrow and I give you a ride home tomorrow, which can both occur concurrently.

The fourth statement

p∨q is true because it asserts that either it rains tomorrow or I give you a ride home tomorrow. At least one of the conditions can happen independently of the other, making the statement correct.

The solution to the given difference equation with the specified auxiliary conditions is [tex]\[y[n] = -\frac{2}{3}(-2)^n + \frac{5}{3}(-1)^n + \frac{2}{3}\cdot u[n]\][/tex].

We first need to find the homogeneous solution to solve the given difference equation and then determine the particular solution.

To find the homogeneous solution, we set the right side of the equation to 0:

[tex]\[y_h[n] + 3y_h[n-1] + 2y_h[n-2] = 0\][/tex]

The characteristic equation is obtained by replacing [tex]\(y_h[n]\) with \(r^n\)[/tex] and solving for r:

[tex]\[r^2 + 3r + 2 = 0\][/tex]

Factoring the equation, we get:

[tex]\[(r + 2)(r + 1) = 0\][/tex]

This gives us two roots: [tex]\(r_1 = -2\) and \(r_2 = -1\).[/tex]

The general homogeneous solution is then given by:

[tex]\[y_h[n] = A(-2)^n + B(-1)^n\][/tex]

To find the particular solution, we assume y_p[n] has the same form as x[n], but with different coefficients. Since the input is x[n] = u[n], we assume the particular solution to be a step function [tex]\(y_p[n] = K\cdot u[n]\)[/tex], where K is a constant.

Substituting y_p[n] and x[n] into the difference equation, we have:

[tex]\[K\cdot u[n] + 3K\cdot u[n-1] + 2K\cdot u[n-2] = u[n-1] + 3u[n-2]\][/tex]

We can solve this equation by comparing the coefficients on both sides:

[tex]\[K + 3K + 2K = 1 + 3 \cdot 1\][/tex]

Simplifying, we find [tex]\(6K = 4\)[/tex], which gives [tex]\(K = \frac{2}{3}\)[/tex].

Therefore, the particular solution is [tex]\(y_p[n] = \frac{2}{3}\cdot u[n]\).[/tex]

The general solution is obtained by adding the homogeneous and particular solutions:

[tex]\[y[n] = y_h[n] + y_p[n]\][/tex]

[tex]\[y[n] = A(-2)^n + B(-1)^n + \frac{2}{3}\cdot u[n]\][/tex]

Using the auxiliary conditions [tex]\(y[0] = 1\) and \(y[1] = 2\)[/tex], we can find the values of [tex]\(A\) and \(B\)[/tex]:

[tex]\[y[0] = A(-2)^0 + B(-1)^0 + \frac{2}{3}\cdot u[0] = A + B + \frac{2}{3} = 1\][/tex]

[tex]\[y[1] = A(-2)^1 + B(-1)^1 + \frac{2}{3}\cdot u[1] = -2A - B + \frac{2}{3} = 2\][/tex]

Solving these equations, we find [tex]\(A = -\frac{2}{3}\) and \(B = \frac{5}{3}\)[/tex].

Therefore, the solution to the given difference equation with the specified auxiliary conditions is [tex]\[y[n] = -\frac{2}{3}(-2)^n + \frac{5}{3}(-1)^n + \frac{2}{3}\cdot u[n]\][/tex].

The function f(x) = cos(a⁶ + x⁶) is given. To find the derivative f′(x), we can apply the chain rule. The derivative of f(x) = cos(a⁶ + x⁶) is f′(x) = -sin(a⁶ + x⁶) * (6x⁵).

The chain rule states that if we have a composite function, such as f(g(x)), then the derivative is equal to the derivative of the outer function evaluated at the inner function, multiplied by the derivative of the inner function.

In this case, the outer function is the cosine function, and the inner function is a⁶ + x⁶. The derivative of the cosine function is -sin(a⁶ + x⁶), and the derivative of the inner function with respect to x is 6x⁵.

Applying the chain rule, we have:

f′(x) = -sin(a⁶ + x⁶) * (6x⁵).

So the derivative of f(x) = cos(a⁶ + x⁶) is f′(x) = -sin(a⁶ + x⁶) * (6x⁵).

This derivative gives us the rate of change of the function f(x) with respect to x. It tells us how the function is changing as we vary the value of x.

To evaluate the definite integral ∫[1, 2] (2x^2 + 4) / x^2 dx, we will find the antiderivative of the integrand and apply the Fundamental Theorem of Calculus. The result will be a numeric value representing the area under the curve between the limits of integration.

To evaluate the definite integral, we first find the antiderivative of the integrand. For the term 2x^2, the antiderivative is (2/3)x^3. For the constant term 4, the antiderivative is 4x.

Applying the Fundamental Theorem of Calculus, we evaluate the antiderivative at the upper and lower limits of integration.

Substituting the upper limit, x = 2, into the antiderivative function, we have [(2/3)(2)^3 + 4(2)].

Substituting the lower limit, x = 1, into the antiderivative function, we have [(2/3)(1)^3 + 4(1)].

We subtract the value at the lower limit from the value at the upper limit to find the definite integral.

Simplifying the expression, we get [(16/3) + 8] - [(2/3) + 4].

We are given vector difference V′=V2−V1 and we have to find the magnitude of the vector difference V′ and the angle which V′ makes with the positive x-axis.

(a) Graphical Analysis

From the above graph, we can say that V′=V2−V1and can find its magnitude using the following formula:|V′|=√(V′x)²+(V′y)²|V′|=√((2-1)²+(-5-(-3))²)=√2²+(-2)²=√8

Now, we have to find the angle which V′ makes with the positive x-axis.

From the above graph, we can see that

tan =V′yV′xtan =(-2)/(2-1)=-2

For the given problem, we have tan <0 and we have to find the between 180° and 270° as the resultant vector lies in the third quadrant.

Hence,=tan⁻¹2=63.43°

The magnitude of the vector difference V′ is √8 units and the angle which V′ makes with the positive x-axis is 63.43°.

(b) Analytical Method

Given vectors V1 = 1i - 5j and V2 = 2i - 3j.We know that V′=V2−V1=2i - 3j - (1i - 5j)=2i - 3j - 1i + 5j=1i + 2jHence, we have V′ = 1i + 2j = (1, 2) in Cartesian form.

Now, the magnitude of V′ can be determined using the formula:|V′|=√V′x²+V′y²|V′|=√(1)²+(2)²=√5 unitsAlso, we have to determine the angle made by V′ with the positive x-axis.tan =V′yV′xtan =2/1=2

For the given problem, we have tan >0 and we have to find the between 0° and 90° as the resultant vector lies in the first quadrant.

Hence,=tan⁻¹2=63.43°

∴ The magnitude of the vector difference V′ is √5 units and the angle which V′ makes with the positive x-axis is 63.43°.
