At x = -4, there is a local maximum because the concavity changes from upward (concave up) to downward (concave down)

To find the first derivative of g(x) = 6x^3 + 45x^2 + 72x, we differentiate term by term using the power rule:

g'(x) = 3(6x^2) + 2(45x) + 72

      = 18x^2 + 90x + 72

To find the second derivative, we differentiate g'(x):

g''(x) = 2(18x) + 90

       = 36x + 90

Now, we evaluate g''(-4) by substituting x = -4 into the second derivative:

g''(-4) = 36(-4) + 90

        = -144 + 90

        = -54

Since g''(-4) is negative (-54 < 0), the graph of g(x) is concave down at x = -4. Therefore, at x = -4, there is a local maximum because the concavity changes from upward (concave up) to downward (concave down).

The power series representation centered at x=0 for the function f(x) = x^2 / (1+5x) is given by f(x) = x^2 / (1+5x) are x^2, -5x^3, 25x^4, -125x^5, and so on.

To find the power series representation of the function f(x), we can use the geometric series expansion formula:

1 / (1 - r) = 1 + r + r^2 + r^3 + ...

In this case, our function is f(x) = x^2 / (1+5x). We can rewrite it as f(x) = x^2 * (1/(1+5x)).

Now we can apply the geometric series expansion to the term (1/(1+5x)):

(1 / (1+5x)) = 1 - 5x + 25x^2 - 125x^3 + ...

To find the power series representation of f(x), we multiply each term in the expansion of (1/(1+5x)) by x^2:

f(x) = x^2 * (1 - 5x + 25x^2 - 125x^3 + ...)

Expanding this further, we get:

F(x) = x^2 - 5x^3 + 25x^4 - 125x^5 + ...

Therefore, the first five non-zero terms of the power series representation centered at x=0 for the function f(x) = x^2 / (1+5x) are x^2, -5x^3, 25x^4, -125x^5, and so on.

Any sequence of the form x(n) = An₊¹r⁻ⁿ, where 0 < r < 18, has a Discrete Time Fourier Transform of the form  X(ω) = AΠ⁻¹(r - r⁻¹e⁻²iω).

The Z-transform of a sequence x(n) is defined as

X(z) = ∑ₙ x(n)z⁻ⁿ

Our given z-transform is:

X(z) = 1/(z+a)² (z+b)(z+c)

where a=18; b=-17; c=2

We can rewrite our transform as:

X(z) = 1/ z² (1-a/z) (1+b/z) (1+c/z)

Let's consider the convergence domain of our transform, which represents all of the z-values in the complex plane for which x(n) and X(z) are analytically related. Since our transform is a rational function, the domain is the region in the complex plane for which all poles (roots of denominator) lie outside the circle.

Thus, our convergence domain is |z| > max{18, -17, 2} = |z| > 18

Let's now consider all of the possible sequences that lead to this transform, depending on the convergence domain. Since our domain is |z| > 18, the possible sequences are those with values that approach zero for x(n) > 18. Thus, any sequence with the form of x(n) = An+¹r⁻ⁿ, where An is a constant and 0 < r < 18, is a possible sequence for our transform.

To determine which of these sequences have a Discrete Time Fourier Transform, we need to take the Fourier Transform of the sequence. To do so, we can use the formula:

X(ω) = ∫x(t)e⁻ⁱωt  dt

To calculate the Discrete Time Fourier Transform of a sequence with the form of x(n)= An+¹r⁻ⁿ, we can use the formula:

X(ω) = AΠ⁻¹(r - r⁻¹e⁻²iω)

Therefore, any sequence of the form x(n) = An+¹r⁻ⁿ, where 0 < r < 18, has a Discrete Time Fourier Transform of the form  X(ω) = AΠ⁻¹(r - r⁻¹e⁻²iω).

Simplifying the expression inside the integral: [ X(omega) = frac{16}{(3pi)^2} left(frac{1}{2} delta(omega) - \frac{1}{4}

To find the Fourier transform of ( x(t) = 16 operator name{sinc}^{2}(3t)), we can use the definition of the Fourier transform. The Fourier transform of a function ( x(t) ) is given by:

[ X(omega) = int_{-infty}^{infty} x(t) e^{-j omega t} , dt ]

where ( X(omega) ) is the Fourier transform of ( x(t) ), (omega ) is the angular frequency, and ( j ) is the imaginary unit.

In this case, we have ( x(t) = 16 operatorbname{sinc}^{2}(3t)). The ( operator name {sinc}(x) ) function is defined as (operatornname{sinc}(x) = frac{sin(pi x)}{pi x} ).

Let's substitute this into the Fourier transform integral:

[ X(omega) = int_{-infty}^{infty} 16 left(frac{sin(3pi t)}{3pi t}right)^2 e^{-j \omega t} , dt ]

We can simplify this expression further. Let's break it down step by step:

[ X(omega) = frac{16}{(3pi)^2} int_{-infty}^{infty} \sin^2(3pi t) e^{-j omega t} , dt ]

Using the trigonometric identity ( sin^2(x) = \frac{1}{2} - \frac{1}{2} cos(2x) ), we can rewrite the integral as:

[ X(omega) = frac{16}{(3pi)^2} int_{-infty}^{infty} left(frac{1}{2} - frac{1}{2} cos(6\pi t)right) e^{-j omega t} , dt ]

Expanding the integral, we get:

[ X(\omega) = frac{16}{(3pi)^2} left(frac{1}{2} int_{-infty}^{infty} e^{-j omega t} , dt - frac{1}{2} int_{-infty}^{infty} cos(6pi t) e^{-j omega t} , dtright) ]

The first integral on the right-hand side is the Fourier transform of a constant, which is given by the Dirac delta function. Therefore, it becomes ( delta(omega) ).

There is no number "c" that satisfies the M.V.T. for f(x) = x/(x + 2) on the interval [1, π].

To apply the Mean Value Theorem (M.V.T.), we need to check if the function is continuous on the closed interval [a, b] and differentiable on the open interval (a, b). If these conditions are met, then there exists a number "c" in (a, b) such that the derivative of the function at "c" is equal to the average rate of change of the function over the interval [a, b].

Let's calculate the number "c" for each given function:

(a) f(x) = e^(-x), [0, 2]

First, let's check if the function is continuous on [0, 2] and differentiable on (0, 2).

1. Continuity: The function f(x) = e^(-x) is continuous everywhere since it is composed of exponential and constant functions.

2. Differentiability: The function f(x) = e^(-x) is differentiable everywhere since the exponential function is differentiable.

Since the function is both continuous on [0, 2] and differentiable on (0, 2), we can apply the M.V.T. to find the value of "c."

The M.V.T. states that there exists a number "c" in (0, 2) such that:

f'(c) = (f(2) - f(0))/(2 - 0)

To find "c," we need to calculate the derivative of f(x):

f'(x) = d/dx(e^(-x)) = -e^(-x)

Now we can solve for "c":

-c*e^(-c) = (e^(-2) - e^0)/2

We can simplify the equation further:

-c*e^(-c) = (1/e^2 - 1)/2

-c*e^(-c) = (1 - e^2)/(2e^2)

Since this equation does not have an analytical solution, we can use numerical methods or a calculator to approximate the value of "c." Solving this equation numerically, we find that "c" ≈ 1.1306.

Therefore, the number "c" that satisfies the M.V.T. for f(x) = e^(-x) on the interval [0, 2] is approximately 1.1306.

(b) f(x) = x/(x + 2), [1, π]

Similarly, let's check if the function is continuous on [1, π] and differentiable on (1, π).

1. Continuity: The function f(x) = x/(x + 2) is continuous everywhere except at x = -2, where it is undefined.

2. Differentiability: The function f(x) = x/(x + 2) is differentiable on the open interval (1, π) since it is a rational function.

Since the function is continuous on [1, π] and differentiable on (1, π), we can apply the M.V.T. to find the value of "c."

The M.V.T. states that there exists a number "c" in (1, π) such that:

f'(c) = (f(π) - f(1))/(π - 1)

To find "c," we need to calculate the derivative of f(x):

f'(x) = d/dx(x/(x + 2)) = 2/(x + 2)^2

Now we can solve for "c":

2/(c + 2)^2 = (π/(π + 2) - 1)/(π - 1)

Simplifying the equation:

2/(c + 2)^2 = (

π - (π + 2))/(π + 2)(π - 1)

2/(c + 2)^2 = (-2)/(π + 2)(π - 1)

Simplifying further:

1/(c + 2)^2 = -1/((π + 2)(π - 1))

Now, solving for "c," we can take the reciprocal of both sides and then the square root:

(c + 2)^2 = -((π + 2)(π - 1))

Taking the square root of both sides:

c + 2 = ±sqrt(-((π + 2)(π - 1)))

Since the right-hand side of the equation is negative, there are no real solutions for "c" that satisfy the M.V.T. for f(x) = x/(x + 2) on the interval [1, π].

Therefore, there is no number "c" that satisfies the M.V.T. for f(x) = x/(x + 2) on the interval [1, π].

To prove that 3 is a factor of 4ⁿ - 1 for all positive integers, we can use mathematical induction to demonstrate that the statement holds true for any arbitrary positive integer n.

We will prove this statement using mathematical induction. Firstly, we establish the base case, which is n = 1. In this case, 4ⁿ - 1 equals 4 - 1, which is 3, and 3 is divisible by 3. Hence, the statement is true for n = 1.

Next, we assume that the statement holds true for some arbitrary positive integer k. That is, 4ᵏ - 1 is divisible by 3. Now, we need to prove that the statement also holds true for k + 1.

To do so, we consider 4^(k+1) - 1. By using the laws of exponents, this expression can be rewritten as (4^k * 4) - 1. We can further simplify it to (4^k - 1) * 4 + 3.

Since we assumed that 4^k - 1 is divisible by 3, let's denote it as m, where m is an integer. Therefore, we can express 4^(k+1) - 1 as m * 4 + 3.

Now, observe that m * 4 is divisible by 3 since 3 divides m and 3 divides 4. Additionally, 3 is divisible by 3. Therefore, m * 4 + 3 is also divisible by 3.

Hence, by the principle of mathematical induction, we have proven that 3 is a factor of 4ⁿ - 1 for all positive integers.

The work required to pump half of the water to the top of the tank is approximately 65,334 Joules.

1. The first step is to find the volume of water in the tank. Since the shape of the tank is an inverted circular cone, we can use the formula for the volume of a cone: V = (1/3) * π * [tex]r^2[/tex] * h, where V is the volume, π is a mathematical constant (approximately 3.14159), r is the radius, and h is the height. Plugging in the values, we get V = (1/3) * 3.14159 * [tex]3^2[/tex] * 4 = 37.6991 cubic meters.

2. Half of the water in the tank would be equal to half of the volume, so the volume of water to be pumped is 37.6991 / 2 = 18.8495 cubic meters.

3. Next, we need to calculate the mass of the water to be pumped. We can use the formula m = ρ * V, where m is the mass, ρ is the density of water, and V is the volume. Given that the density of water is 1000 [tex]kg/m^3[/tex], we get m = 1000 * 18.8495 = 18,849.5 kilograms.

4. The work required to pump the water to the top of the tank can be calculated using the formula W = m * g * h, where W is the work, m is the mass, g is the acceleration due to gravity (approximately 9.8 [tex]m/s^2[/tex]), and h is the height. Plugging in the values, we have W = 18,849.5 * 9.8 * 4 = 737,586 Joules.

5. However, we only need to find the work required to pump half of the water, so the final answer is half of the calculated value: 737,586 / 2 = 368,793 Joules.

Thus, the final answer of this differentiation  is dQ/dt = (-5cos t * sin t) / √(4sin²t + 4cos²t + cos²t), by using chain rule.

Q = √(4x² + 4y² + z²);

x = sin t;

y = cos t;

z = cos t

We have to find dQ/dt by applying the Chain Rule.

Step-by-step explanation:

Using the Chain Rule, we get:

Q' = dQ/dt = ∂Q/∂x * dx/dt + ∂Q/∂y * dy/dt + ∂Q/∂z * dz/dt

∂Q/∂x = 1/2 (4x² + 4y² + z²)^(-1/2) * (8x) = 4x / Q

∂Q/∂y = 1/2 (4x² + 4y² + z²)^(-1/2) * (8y) = 4y / Q

∂Q/∂z = 1/2 (4x² + 4y² + z²)^(-1/2) * (2z)

= z / Q

dx/dt = cos t

dy/dt = -sin t

dz/dt = -sin t

Substituting these values in the expression of dQ/dt, we get:

dQ/dt = 4x/Q * cos t + 4y/Q * (-sin t) + z/Q * (-sin t)dQ/dt

= [4sin t/√(4sin²t + 4cos²t + cos²t)] * cos t + [4cos t/√(4sin²t + 4cos²t + cos²t)] * (-sin t) + [cos t/√(4sin²t + 4cos²t + cos²t)] * (-sin t)

(Substituting values of x, y, and z)

dQ/dt = (4sin t * cos t - 4cos t * sin t - cos t * sin t) / √(4sin²t + 4cos²t + cos²t)

dQ/dt = (-5cos t * sin t) / √(4sin²t + 4cos²t + cos²t)

So, first we take the derivative of f(x) with respect to x:

[tex]$$f'(x) = 2xe^{x^2}$$[/tex]

Then we take the derivative again:

[tex]$$f''(x) = (2x)^2 e^{x^2} + 2e^{x^2}$$[/tex]

Now, we evaluate this expression at x = 0:

[tex]$$f''(0) = 2 \cdot 0^2 e^{0^2} + 2e^{0^2} = 2$$[/tex]

Finally, we divide by 2! to get the coefficient of x²:

[tex]$$\frac{f''(0)}{2!} = \frac{2}{2!} = \boxed{\frac{1}{4}}$$[/tex]

Therefore, the coefficient of x² in the Maclaurin series for f(x) = exp(x²) is 1/4.

The relation R is not transitive because the statement ∀x∀y∀z.R(x, y) is not sufficient to establish transitivity. Transitivity requires that if R(x, y) and R(y, z) are true, then R(x, z) must also be true for all x, y, and z. However, the given statement only asserts the existence of a relation between x and y, without specifying any relationship between y and z. Therefore, we cannot conclude that R is transitive based on the given condition.

Transitivity is a property of relations that states if there is a relation between two elements and another relation between the second element and a third element, then there must be a relation between the first and third elements. In the case of relation A(x, y) defined in the question, A is true if and only if the sets x and y have the same size (denoted by |x| = |y|).

To check transitivity, we need to examine whether the given condition ∀x∀y∀z.R(x, y) implies transitivity. However, the statement ∀x∀y∀z.R(x, y) simply asserts the existence of a relation between any elements x and y, without specifying any relationship between y and z. In other words, it does not guarantee that if there is a relation between x and y, and a relation between y and z, there will be a relation between x and z.

To illustrate this, consider the following counterexample: Let x = {1, 2}, y = {3, 4}, and z = {5, 6}. Here, |x| = |y| and |y| = |z|, satisfying the condition of relation A. However, there is no relation between x and z since |x| ≠ |z|. Therefore, the given condition does not establish transitivity for relation A.

In conclusion, the relation A(x, y) defined in the question is not transitive based on the given condition. Additional conditions or constraints would be required to ensure transitivity.

The result of the subtraction DA231₁₆ - CAD1₁₆ is 1113₁₆.

To calculate the subtraction DA231₁₆ - CAD1₁₆, we need to perform the subtraction digit by digit.

```

  DA231₁₆

-  CAD1₁₆

---------

```

Starting from the rightmost digit, we subtract C from 1. Since C represents the value 12 in hexadecimal, we can rewrite it as 12₁₀.

```

  DA231₁₆

- CAD1₁₆

---------

          1

```

1 - 12 results in a negative value. To handle this, we borrow 16 from the next higher digit.

```

  DA231₁₆

        11

```

Next, we subtract A from 3. A represents the value 10 in hexadecimal.

```

  DA231₁₆

- CAD1₁₆

---------

       11

```

3 - 10 results in a negative value, so we borrow again.

- CAD1₁₆

---------

      111

```

Moving on, we subtract D from 2.

```

To transform a system from the time domain to the frequency domain, you need to perform a Fourier transform.

The process of transforming a system from the time domain to the frequency domain involves the use of a mathematical operation called the Fourier transform. The Fourier transform allows us to represent a signal or a system in terms of its frequency components. Here are the steps involved:

Start with a signal or system that is represented in the time domain. In the time domain, the signal is described as a function of time.

Apply the Fourier transform to the time-domain signal. The Fourier transform mathematically converts the signal from the time domain to the frequency domain.

The result of the Fourier transform is a complex function called the frequency spectrum. This spectrum represents the signal in terms of its frequency components.

The frequency spectrum provides information about the amplitudes and phases of different frequency components present in the original time-domain signal.

The inverse Fourier transform can be used to convert the frequency spectrum back to the time domain if desired.

By performing the Fourier transform, we can analyze signals or systems in the frequency domain, which is particularly useful for tasks such as filtering, noise removal, and modulation analysis.

The parametric equations of the line passing through the points (1, 4, -2) and (-3, 5, 0) can be determined by finding the direction vector of the line and using one of the given points as the initial point.

The direction vector of the line is obtained by subtracting the coordinates of the initial point from the coordinates of the terminal point. Thus, the direction vector is (-3 - 1, 5 - 4, 0 - (-2)), which simplifies to (-4, 1, 2).Using the point (1, 4, -2) as the initial point, the parametric equations of the line are:

x = 1 - 4t

y = 4 + t

z = -2 + 2t

In these equations, t represents a parameter that can take any real value. By substituting different values of t, we can obtain different points on the line.The parametric equations of the line passing through the points (1, 4, -2) and (-3, 5, 0) are x = 1 - 4t, y = 4 + t, and z = -2 + 2t.

The pole-zero map of a transfer function is a graphical representation of the zeros and poles of the transfer function. The zeros of a transfer function are the values of s that make the transfer function equal to zero. The poles of a transfer function are the values of s that make the denominator of the transfer function equal to zero.

The stability of a system can be determined by looking at the pole-zero map. If all of the poles of the transfer function are located in the left-hand side of the complex plane, then the system is stable. If any of the poles of the transfer function are located in the right-hand side of the complex plane, then the system is unstable.

In this case, the pole-zero map has one pole at s = -1 and two zeros at s = 0 and s = -11. The pole at s = -1 is located in the left-hand side of the complex plane, so the system is stable.

(b) the curve x = 2 + 2sinθ, y = 1 + cosθ has points of horizontal tangency at θ = nπ and points of vertical tangency at θ = (2n + 1)π/2.

(c) the polar curve r = 1 - cosθ has points of horizontal tangency at θ = nπ and no points of vertical tangency.

To find the points of horizontal and vertical tangency, we need to find where the derivative of the curve is zero or undefined.

(a) For the curve x = t + 2, y = t³ - 2t:

To find the points of horizontal tangency, we set dy/dt = 0:

dy/dt = 3t² - 2 = 0

3t² = 2

t² = 2/3

t = ±√(2/3)

To find the points of vertical tangency, we set dx/dt = 0:

dx/dt = 1 = 0

This equation has no solution since 1 is not equal to zero.

Therefore, the curve x = t + 2, y = t³ - 2t has points of horizontal tangency at t = ±√(2/3), and no points of vertical tangency.

(b) For the curve x = 2 + 2sinθ, y = 1 + cosθ:

To find the points of horizontal tangency, we set dy/dθ = 0:

dy/dθ = -sinθ = 0

sinθ = 0

θ = nπ, where n is an integer

To find the points of vertical tangency, we set dx/dθ = 0:

dx/dθ = 2cosθ = 0

cosθ = 0

θ = (2n + 1)π/2, where n is an integer

Therefore, the curve x = 2 + 2sinθ, y = 1 + cosθ has points of horizontal tangency at θ = nπ and points of vertical tangency at θ = (2n + 1)π/2.

(c) For the polar curve r = 1 - cosθ:

To find the points of horizontal tangency, we set dr/dθ = 0:

dr/dθ = sinθ = 0

θ = nπ, where n is an integer

To find the points of vertical tangency, we set dθ/dr = 0:

dθ/dr = 1/sinθ = 0

Therefore, the value of c that satisfies the Mean Value Theorem for the function [tex]f(x) = x^4 - x[/tex] on the interval [0, 2] is c = ∛2.

To find the critical numbers of the function [tex]f(x) = x^(2/3)(x-1)^2[/tex], we need to determine the values of x where the derivative of f(x) is equal to zero or undefined.

First, let's find the derivative of f(x):

[tex]f'(x) = (2/3)x^(-1/3)(x-1)^2 + 2x^(2/3)(x-1)[/tex]

To find the critical numbers, we set f'(x) equal to zero and solve for x:

[tex](2/3)x^(-1/3)(x-1)^2 + 2x^(2/3)(x-1) = 0[/tex]

Simplifying the equation and factoring out common terms:

[tex](2/3)x^(-1/3)(x-1)(x-1) + 2x^(2/3)(x-1) = 0\\(2/3)x^(-1/3)(x-1)[(x-1) + 3x^(2/3)] = 0[/tex]

Now we have two factors: (x-1) = 0 and [tex][(x-1) + 3x^(2/3)] = 0[/tex]

From the first factor, we find x = 1.

For the second factor, we solve:

[tex](x-1) + 3x^(2/3) = 0\\x - 1 + 3x^(2/3) = 0[/tex]

Unfortunately, there is no algebraic solution for this equation. We can approximate the value of x using numerical methods or calculators. One possible solution is x ≈ 0.25.

So the critical numbers of the function [tex]f(x) = x^(2/3)(x-1)^2[/tex] are x = 1 and x ≈ 0.25.

As for the Mean Value Theorem, to find the value of c that satisfies the theorem for the function [tex]f(x) = x^4 - x[/tex] on the interval [0, 2], we need to verify two conditions:

f(x) is continuous on the closed interval [0, 2]: The function [tex]f(x) = x^4 - x[/tex] is a polynomial function, and polynomials are continuous for all real numbers.

f(x) is differentiable on the open interval (0, 2): The function [tex]f(x) = x^4 - x[/tex] is a polynomial, and polynomials are differentiable for all real numbers.

Since both conditions are satisfied, the Mean Value Theorem applies to the function f(x) on the interval [0, 2]. According to the Mean Value Theorem, there exists at least one value c in the open interval (0, 2) such that:

f'(c) = (f(2) - f(0))/(2 - 0)

To find c, we calculate the derivative of f(x):

[tex]f'(x) = 4x^3 - 1[/tex]

Substituting [tex]f(2) = 2^4 - 2 = 14[/tex] and f(0) = 0 into the equation, we have:

f'(c) = (14 - 0)/(2 - 0)

[tex]4c^3 - 1 = 14/2\\4c^3 - 1 = 7\\4c^3 = 8\\c^3 = 2[/tex]

c = ∛2
