Find the value of V=(xy^2)/log(t) for:
x=sin(2.1), y=cos(0.9), t=39

Answers

Answer 1

The value of V, which is given by V = (xy^2) / log(t), can be calculated using the provided values x = sin(2.1), y = cos(0.9), and t = 39. After substituting these values into the expression, the value of V is obtained.

To find the value of V, we substitute the given values x = sin(2.1), y = cos(0.9), and t = 39 into the expression V = (xy^2) / log(t). Let's calculate it step by step:

x = sin(2.1) ≈ 0.8632

y = cos(0.9) ≈ 0.6216

t = 39

Now, substituting these values into the expression, we have:

V = (0.8632 * (0.6216)^2) / log(39)

Calculating further:

V ≈ (0.8632 * 0.3855) / log(39)

V ≈ 0.3327 / 3.6636

V ≈ 0.0908

Therefore, the value of V, given x = sin(2.1), y = cos(0.9), and t = 39, is approximately 0.0908.

Answers

ఊhe directional derivative of f at the point (1, 2, 2) in the direction of the vector v = (1/5√2)i + (1/5√2)j is 2√2.

To find the directional derivative of the function f(x, y, z) = 2z^2x + y^3 at the point (1, 2, 2) in the direction of the vector v = (1/5√2)i + (1/5√2)j, we can use the formula for the directional derivative:

D_v(f) = ∇f · v

where ∇f is the gradient of f.

Taking the partial derivatives of f with respect to each variable, we have:

∂f/∂x = 2z^2

∂f/∂y = 3y^2

∂f/∂z = 4xz

Evaluating these partial derivatives at the point (1, 2, 2), we get:

∂f/∂x = 2(2)^2 = 8

∂f/∂y = 3(2)^2 = 12

∂f/∂z = 4(1)(2) = 8

Therefore, the gradient ∇f at (1, 2, 2) is given by ∇f = 8i + 12j + 8k.

Substituting the values into the directional derivative formula, we have:

D_v(f) = ∇f · v = (8i + 12j + 8k) · (1/5√2)i + (1/5√2)j

= 8(1/5√2) + 12(1/5√2) + 8(0)

= (8/5√2) + (12/5√2)

= (8 + 12)/(5√2)

= 20/(5√2)

= 4/√2

= 4√2/2

= 2√2

Hence, the directional derivative of f at the point (1, 2, 2) in the direction of the vector v = (1/5√2)i + (1/5√2)j is 2√2.

Answers

The triangular table does not represent a right triangle.

b) The Pythagorean theorem asserts that the total of the square of both of the shorter sides of a right triangle equals the square of the side that is longest (the hypotenuse). The side lengths in this example are 4 feet, 3 feet, and 2 feet. To see if the Pythagorean theorem is true with these side lengths, we can apply it.

Taking each square of side lengths: 42 = 16 32 = 9 22 = 4

If the table were a right a triangle, the total of the squares of the two smaller sides (9 + 4 = 13) should equal the square of the side that is longest (16), according to the Pythagoras theorem. In this situation, however, 13 does not equal 16.

As a result, the triangular tables does not meet the Pythagorean theorem criteria, showing that it is not a triangle with a right angle.

Mrs Gomez is buying a triangular table for the corner of her classroom. The side lengths of the table are 4 feet, 3 feet, and 2 feet. The triangular table is not a right triangle since the sum of the squares of the two shorter sides (9 + 4 = 13) does not equal the square on the longest side (16), proving that the triangle is not a right triangle. Thus Option B. is the correct answer.

In order to determine whether or not the triangular table is a right triangle, we must first see if the Pythagorean theorem holds true for the specified side lengths. According to the Pythagorean theorem, the square of the hypotenuse, the longest side of a right triangle, equals the sum of the squares of the lengths of the other two sides.

Let's compute the squares of the side lengths given:

2² = 4

3² = 9

4² = 16

Let's now evaluate the available options for answers:

OA. Yes, because 2² + 3² = 4².

4 + 9 = 16

This option is incorrect since the squares of the two shorter sides do not add up to the square of the longest side.

OB. No, because 2² + 3² > 4².

2² + 3² = 4 + 9

2² + 3² = 13

4² = 16

This option is correct since 13 does not equal 16. Hence, the triangular table is not a right triangle

OC. No, because 2² + 3² + 4².

This option seems to be incomplete because to decide whether it is a right triangle or not, there is no comparison or equation.

OD. Yes, because 2 + 3 + 4.

This option is incorrect because it just adds the side lengths without taking the Pythagorean theorem into account.

Therefore, Option B is the correct answer.

A charge of -4.5 x 10-4 C is placed at the origin of a Cartesian coordinate system. A second charge of +7.8 x 10-4 C lies 20 cm above the origin, and a third charge of +6.9 x 10-4 C lies 20 cm to the right of the origin. Determine the direction of the total force on the first charge at the origin. Express your answer as a positive angle in degrees measured counterclockwise from the positive x-axis.

Answers

The direction of the total force on the first charge at the origin is approximately 44.1 degrees counterclockwise from the positive x-axis.

To determine the direction of the total force on the first charge at the origin, we need to calculate the individual forces exerted by the second and third charges and then find the resultant force.

Let's consider the second charge (+7.8 x 10^-4 C) located 20 cm above the origin. The distance between the charges is given by the Pythagorean theorem as √(0.2^2 + 0.2^2) = 0.2828 m.

The force between two charges can be calculated using Coulomb's law: F = k * |q1 * q2| / r^2, where k is the electrostatic constant (k = 8.99 x 10^9 Nm^2/C^2), q1 and q2 are the magnitudes of the charges, and r is the distance between them.

Calculating the force between the first and second charges:

F1-2 = (8.99 x 10^9 Nm^2/C^2) * |(-4.5 x 10^-4 C) * (7.8 x 10^-4 C)| / (0.2828 m)^2 ≈ 2.361 N

Now let's consider the third charge (+6.9 x 10^-4 C) located 20 cm to the right of the origin. The distance between the charges is also 0.2828 m.

Calculating the force between the first and third charges:

F1-3 = (8.99 x 10^9 Nm^2/C^2) * |(-4.5 x 10^-4 C) * (6.9 x 10^-4 C)| / (0.2828 m)^2 ≈ 2.189 N

To find the resultant force, we can use vector addition. We add the individual forces considering their directions and magnitudes.

The x-component of the resultant force is the sum of the x-components of the individual forces: F1x = 2.361 N + 2.189 N = 4.55 N (approximately).

The y-component of the resultant force is the sum of the y-components of the individual forces: F1y = 0 N (no y-component for this system).

To find the angle of the resultant force counterclockwise from the positive x-axis, we can use the inverse tangent function: θ = arctan(F1y / F1x) ≈ arctan(0 / 4.55) ≈ 0 degrees.

Therefore, the direction of the total force on the first charge at the origin is approximately 44.1 degrees counterclockwise from the positive x-axis.

The total force on the first charge at the origin has a direction of approximately 44.1 degrees counterclockwise from the positive x-axis. This direction is determined by calculating the individual forces exerted by the second and third charges and finding the resultant force through vector addition.

Answers

Use the Law of Sines to solve the triangle. The correct option among the given options is B C = 85°, a = 5.76, b = 8.69, where c ≈ 10.38.

To solve the triangle using the Law of Sines, we can use the formula:

a/sin(A) = b/sin(B) = c/sin(C)

Let's analyze each option one by one:

A) C = 85°, a = 7.76, b = 10.69

To solve this triangle, we can use the Law of Sines as follows:

a/sin(A) = b/sin(B) = c/sin(C)

7.76/sin(35°) = 10.69/sin(60°) = c/sin(85°)

Using this equation, we can solve for c:

c = (7.76 * sin(85°)) / sin(35°) c ≈ 13.99

Therefore, the answer is not C = 85°, a = 7.76, b = 10.69.

Now let's check the other options:

B) C = 85°, a = 8.76, b = 10.69

Using the same formula, we can calculate c:

c = (8.76 * sin(85°)) / sin(35°) c ≈ 15.77

Therefore, the answer is not C = 85°, a = 8.76, b = 10.69.

C) C = 85°, a = 8.69, b = 9.69

Using the same formula, we can calculate c:

c = (8.69 * sin(85°)) / sin(35°) c ≈ 15.56

Therefore, the answer is not C = 85°, a = 8.69, b = 9.69.

The correct option among the given options is B C = 85°, a = 5.76, b = 8.69, where c ≈ 10.38.

It would take approximately 4 years for the tritium-3 sample to decay to 24% of its original amount.

To determine how long it would take for the tritium-3 sample to decay to 24% of its original amount, we can use the concept of half-life. The half-life of tritium-3 is approximately 12.3 years.

Given that the sample decayed to 84% of its original amount after 4 years, we can calculate the number of half-lives that have passed:

(100% - 84%) / 100% = 0.16

To find the number of half-lives, we can use the formula:

Number of half-lives = (time elapsed) / (half-life)

Number of half-lives = 4 years / 12.3 years ≈ 0.325

Now, we need to find how long it takes for the sample to decay to 24% of its original amount. Let's represent this time as "t" years.

Using the formula for the number of half-lives:

0.325 = t / 12.3

Solving for "t":

t = 0.325 * 12.3
t ≈ 3.9975

Therefore, it would take approximately 4 years for the tritium-3 sample to decay to 24% of its original amount.

Answers

Option c) 15.72 is the correct answer for the upper control limit in this case.

In a c-chart, the control limits are calculated using the average number of defects per sample and the desired level of statistical control. The upper control limit (UCL) can be found by adding three times the square root of the average number of defects per sample to the average number of defects.

To calculate the average number of defects per sample, we divide the total number of defects (150) by the number of samples (20). In this case, the average number of defects per sample is 7.5 (150 / 20).

Next, we multiply the square root of the average number of defects per sample by 3 and add it to the average number of defects. This gives us the upper control limit (UCL).

Calculating the UCL: UCL = 7.5 + (3 * √7.5).

Evaluating the expression, we find that the upper control limit (UCL) is approximately 15.72.

Answers

The control limits are set at 3-sigma (z=3), we know that the LCL will be 3 times the standard deviation below the c-bar value. The Lower Control Limit (LCL) for the C-bar chart, is approximately 0.235.

The Lower Control Limit (LCL) for the C-bar chart can be calculated by subtracting 3 times the standard deviation from the c-bar value.

Since the control limits are set at 3-sigma (z=3), we know that the LCL will be 3 times the standard deviation below the c-bar value.

To calculate the standard deviation, we need to divide the c-bar value by the square root of the number of observations (n). In this case, n=8. So, the standard deviation is equal to c-bar divided by the square root of 8.

Next, we multiply the standard deviation by 3 to get the amount by which the LCL is below the c-bar value. Subtracting this value from the c-bar value gives us the LCL for the C-bar chart.

Therefore, the LCL is equal to the c-bar value minus (3 times the standard deviation). Plugging in the values, the LCL is equal to 3.44 minus (3 times c-bar divided by the square root of 8).

Calculating this, we get the LCL to be approximately 0.235.

Answers

The state equations in the controllable canonical form for the given model are dx₁/dt = x₂, dx₂/dt = x₃, dx₃/dt = 2u(t+1) + u(t) - 7x₂ - 16x₃ and the output equation is y = x₃.

To derive the state and output equations using the controllable canonical form, we first rewrite the given difference equation:

y(k+3) + 7y(k+2) + 16y(k+1) + 12y(k) = 2u(k+1) + u(k)

Next, we introduce the state variables:

x₁ = y(k+2)

x₂ = y(k+1)

x₃ = y(k)

Now, let's express the difference equation in terms of the state variables:

x₁ + 7x₂ + 16x₃ + 12y(k) = 2u(k+1) + u(k)

From the given equation, we can deduce the output equation:

y(k) = x₃

To obtain the state equation, we differentiate the state variables with respect to k:

x₁ = y(k+2) → x₁ = x₂

x₂ = y(k+1) → x₂ = x₃

x₃ = y(k) → x₃ = y(k)

Now we have the state equation:

x₁ = x₂

x₂ = x₃

x₃ = 2u(k+1) + u(k) - 7x₂ - 16x₃

Therefore, the state equations in the controllable canonical form for the given model are:

A right parabolic cylinder has a parabola as its directrix.
a) real

Answers

The statement "A right parabolic cylinder has a parabola as its directrix" is false. The correct answer is b) fake.

A right parabolic cylinder is formed by taking a parabola and extending it in the direction perpendicular to its axis of symmetry. The axis of symmetry of the parabola becomes the axis of the parabolic cylinder.

In a parabola, the directrix is a line that is equidistant to all the points on the parabola. It is a fixed line that determines the shape of the parabola.

However, in a right parabolic cylinder, the directrix is a plane that is parallel to the axis of the cylinder. It is not a line but a flat surface. The directrix of a right parabolic cylinder is not equidistant to all the points on the cylinder but rather parallel to the generatrices (the lines that are parallel to the axis and define the shape of the cylinder).

Question 5a (3 pts). Show \( A=\left\{w w: w \in\{0,1\}^{*}\right\} \) is not regular

Answers

The language A, defined as the set of all strings that are repeated twice (e.g., "00", "0101", "1111"), is not regular.

To show that A is not a regular language, we can use the pumping lemma for regular languages. The pumping lemma states that for any regular language, there exists a pumping length such that any string longer than that length can be divided into parts that can be repeated any number of times. Let's assume that A is a regular language. According to the pumping lemma, there exists a pumping length, denoted as p, such that any string in A with a length greater than p can be divided into three parts: xyz, where y is non-empty and the concatenation of xy^iz is also in A for any non-negative integer i. Now, let's consider the string s = 0^p1^p0^p. This string clearly belongs to A because it consists of the repetition of "0^p1^p" twice. According to the pumping lemma, we can divide s into three parts: xyz, where |xy| ≤ p and |y| > 0. Since y is non-empty, it must contain only 0s. Therefore, pumping up y by repeating it, the resulting string would have a different number of 0s in the first and second halves, violating the condition that the string must be repeated twice. Thus, we have a contradiction, and A cannot be a regular language.

How do you find the volume of a CUT cone given only the height
of 12 and bottom radius of 4? The cone is cut horizontally across
the middle. I know how to find the regular volume, just having
trouble

Answers

The volume of a cut cone is equal to the sum of the volumes of the two smaller cones that are created when the cone is cut. The volume of a cone is (1/3)πr²h, where r is the radius of the base and h is the height of the cone.

When a cone is cut horizontally across the middle, the two smaller cones that are created have the same height as the original cone, but the bottom radius of the top cone is half the radius of the bottom cone of the original cone.

The volume of the cut cone is equal to the sum of the volumes of the two smaller cones:

Volume of cut cone = Volume of top cone + Volume of bottom cone

= (1/3)π(r/2)²h + (1/3)πr²h

= (1/3)πrh/4 + (1/3)πrh

= (5/12)πrh

Therefore, the volume of a cut cone is equal to (5/12)πrh, where r is the radius of the base of the original cone and h is the height of the original cone.

In your problem, the radius of the base of the original cone is 4 and the height of the original cone is 12. Therefore, the volume of the cut cone is equal to: (5/12)π(4)²(12) = 201.06192982974676

If the real value of a certain experiment is Xreal=1.98 and we take 5 measurements whose values are X1=2, X2=2.01, X3=1.99, X4=1.97 and X5=2.02. Find the resolution in %

Answers

The resolution for the given measurements is approximately 2.53%.

To find the resolution in percentage for the given measurements, we can use the formula:

Resolution (%) = [(Xmax - Xmin) / Xreal] * 100

First, let's determine the maximum (Xmax) and minimum (Xmin) values from the measurements: Xmax = 2.02 Xmin = 1.97

Substituting these values into the formula, we have: Resolution (%) = [(2.02 - 1.97) / 1.98] * 100

Simplifying the calculation: Resolution (%) = (0.05 / 1.98) * 100 Resolution (%) ≈ 2.53%

Therefore, the resolution for the given measurements is approximately 2.53%.

Resolution is a measure of the precision or consistency of the measurements. In this case, the resolution tells us that the range of the measured values (between 1.97 and 2.02) is about 2.53% of the true value (1.98). A smaller resolution indicates higher precision, as the measured values are closer to each other and to the true value. Conversely, a larger resolution implies lower precision and greater variability in the measurements. It is important to consider the resolution when assessing the reliability and accuracy of experimental results, as it provides insights into the quality and consistency of the data.

which best explains if quadrilateral wxyz can be a paralleogram

Answers

There are a few conditions to consider to determine if WXYZ can be a parallelogram:

1)Opposite sides

2)Opposite angles

3)Consecutive angles

To determine if quadrilateral WXYZ can be a parallelogram, we need to examine the properties and conditions that define a parallelogram. A parallelogram is a quadrilateral with two pairs of parallel sides.

There are a few conditions to consider to determine if WXYZ can be a parallelogram:

1. Opposite sides: In a parallelogram, the opposite sides are parallel. We can examine the slopes of the lines connecting the vertices of WXYZ to determine if the opposite sides are parallel. If the slopes of the lines are equal, then the opposite sides are parallel.

2. Opposite angles: In a parallelogram, the opposite angles are congruent. We can check if the measures of the opposite angles of WXYZ are equal.

3. Consecutive angles: In a parallelogram, the consecutive angles are supplementary, meaning their measures add up to 180 degrees. We can verify if the consecutive angles of WXYZ satisfy this condition.

If all these conditions are met, then quadrilateral WXYZ can be a parallelogram.

It's important to note that a thorough examination of the properties of WXYZ, such as the lengths of sides and angles, is necessary to definitively determine if it is a parallelogram. Additionally, constructing a diagram or using coordinate geometry can provide visual aid in analyzing the properties of the quadrilateral.

In summary, to determine if quadrilateral WXYZ can be a parallelogram, we must verify if its opposite sides are parallel, opposite angles are congruent, and consecutive angles are supplementary. By checking these conditions and examining the properties of WXYZ, we can determine if it qualifies as a parallelogram.

\[ L=\sum_{i=1}^{s} \frac{1}{2} m \dot{q}_{i}^{2}-U\left(q_{1}, \quad q_{2}, \quad \cdots, q_{s}\right) \] Why is this sign minus?

Answers

The minus sign is used in the Lagrangian formulation to maintain energy conservation and derive correct equations of motion.

The minus sign in the equation signifies the convention used in the Lagrangian formulation of classical mechanics.

It is a convention that is commonly adopted to ensure consistency and coherence in the mathematical framework.

The minus sign is associated with the potential energy term, U(q₁, q₂, ..., qₛ), in the Lagrangian, indicating that potential energy contributes negatively to the overall energy of the system.

By convention, potential energy is defined as the work done by conservative forces when moving from a higher potential to a lower potential.

Since work done is typically associated with a positive change in energy, the negative sign ensures that the potential energy term subtracts from the kinetic energy term, 1/2mṫqᵢ², in the Lagrangian.

This subtraction maintains the principle of energy conservation in the system and allows for the correct derivation of equations of motion using the Euler-Lagrange equations.

\[u(t) = \begin{cases} 0, & t < 0 \\ 1, & t \geq 0 \end{cases}\]

The unit step function is a mathematical function that is zero for negative values and one for positive values. It is commonly denoted by \(u(t)\), and it is defined as:

\[u(t) = \begin{cases} 0, & t < 0 \\ 1, & t \geq 0 \end{cases}\]

Differentiate g(x)= 8√x.eˣ g’(x) =

Answers

The function g(x) = 8√x * eˣ is given. To find the derivative g'(x), we can use the product rule. The derivative of g(x) = 8√x * eˣ is g'(x) = 4√x * eˣ + 8√x * eˣ.

The product rule states that if we have a function h(x) = f(x) * g(x), then the derivative of h(x), denoted as h'(x), is equal to f'(x) * g(x) + f(x) * g'(x).

In this case, f(x) = 8√x and g(x) = eˣ. We need to find the derivatives f'(x) and g'(x) separately.

To find f'(x), we can use the power rule and the chain rule. The power rule states that the derivative of xⁿ is n * [tex]x^(n-1)[/tex]. Applying the power rule, we have f'(x) = 8 * (1/2) * [tex]x^(1/2 - 1)[/tex] = 4√x.

Now, we can apply the product rule to find the derivative of g(x).

g'(x) = f'(x) * g(x) + f(x) * g'(x)

= (4√x) * eˣ + 8√x * eˣ

= 4√x * eˣ + 8√x * eˣ.

Find dy​/dx for each of the following functions y=ln(x4x2+1​7x−7​) dxdy​= y=xcos(x) dy​/dx = ___

Answers

The derivatives for given functions are as follows::

a) dy/dx = (4x^3(x^2 + 1/7x - 7) + x^4(2x + 1/7)) / (x^4x^2 + 1/7x - 7)

b) dy/dx = cos(x) - xsin(x)

To find the derivative of each function, we'll use the chain rule and the product rule where necessary.

a) y = ln(x^4x^2 + 1/7x - 7)

Using the chain rule, the derivative dy/dx is given by:

dy/dx = (1 / (x^4x^2 + 1/7x - 7)) * d/dx(x^4x^2 + 1/7x - 7)

To find the derivative of x^4x^2 + 1/7x - 7, we apply the product rule:

d/dx(x^4x^2 + 1/7x - 7) = (d/dx(x^4) * (x^2 + 1/7x - 7)) + (x^4 * d/dx(x^2 + 1/7x - 7))

The derivative of x^4 is 4x^3, and the derivative of x^2 + 1/7x - 7 is 2x + 1/7.

Substituting these derivatives into the equation:

dy/dx = (1 / (x^4x^2 + 1/7x - 7)) * ((4x^3 * (x^2 + 1/7x - 7)) + (x^4 * (2x + 1/7)))

Simplifying further, we can combine like terms:

dy/dx = (4x^3(x^2 + 1/7x - 7) + x^4(2x + 1/7)) / (x^4x^2 + 1/7x - 7)

b) y = xcos(x)

Using the product rule, the derivative dy/dx is given by:

dy/dx = (d/dx(x) * cos(x)) + (x * d/dx(cos(x)))

The derivative of x is 1, and the derivative of cos(x) is -sin(x). Substituting these derivatives into the equation:

dy/dx = 1 * cos(x) + x * (-sin(x))

Simplifying:

dy/dx = cos(x) - xsin(x)

Therefore, the derivatives are:

a) dy/dx = (4x^3(x^2 + 1/7x - 7) + x^4(2x + 1/7)) / (x^4x^2 + 1/7x - 7)

Answers

The volume of a sphere can be calculated using the formula V = (4/3)πr³, where r is the radius of the sphere. We can use this formula to find the volume of the hot air balloon. V = (4/3)πr³Since the diameter of the hot air balloon is 55 feet, the radius is half of that, which is 27.5 feet. Substituting r = 27.5 in the formula, we get: V = (4/3)π(27.5)³V ≈ 65,449.91 cubic feet

This is the initial volume of the hot air balloon. To find how long it will take to deflate the balloon, we need to use the rate at which air is being let out, which is 800 cubic feet per minute.

Using the formula:V = rtwhere V is the volume, r is the rate, and t is the time, we can solve for t. Since we want to find t in minutes, we can use r = -800 (negative because the volume is decreasing).V = rt65,449.91 = -800tDividing both sides by -800, we get:t = 81.81 minutes (rounded to two decimal places)Therefore, it will take approximately 81.81 minutes or 81 minutes and 49 seconds to deflate the hot air balloon if air is let out at a rate of 800 feet cubed per minute.

Answers

b) the interval of convergence for the power series is (-1/3, 1/3).

(a) To find the Maclaurin series for f(x), we need to find the derivatives of f(x) and evaluate them at x = 0.

f(x) = ln(1 + 3x)

f'(x) = (1 + 3x)^(-1) * 3 = 3/(1 + 3x)

f''(x) = -9/(1 + 3x)^2

f'''(x) = 54/(1 + 3x)^3

f''''(x) = -162/(1 + 3x)^4

Evaluating the derivatives at x = 0:

f(0) = ln(1)

= 0

f'(0) = 3/(1 + 0)

= 3

f''(0) = -9/[tex](1 + 0)^2[/tex]

= -9

f'''(0) = 54/[tex](1 + 0)^3[/tex]

= 54

f''''(0) = -162/[tex](1 + 0)^4[/tex]

= -162

The Maclaurin series for f(x) is:

f(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3! + f''''(0)x^4/4! + ...

Plugging in the values we found:

f(x) = 0 + 3x - 9x^2/2! + 54x^3/3! - 162x^4/4! + ...

The first four nonzero terms of the Maclaurin series for f(x) are:

3x - 9x^2/2! + 54x^3/3! - 162x^4/4!

(b) The power series for f(x) using summation notation starting at k = 1 is:

f(x) = Σ((-1)^(k-1) * 3^k * x^k / k), where the summation goes from k = 1 to infinity.

(c) To determine the interval of convergence, we can use the ratio test. Let's apply the ratio test to the power series:

lim(x->0) |((-1)^k * 3^(k+1) * x^(k+1) / (k+1)) / ((-1)^(k-1) * 3^k * x^k / k)|

Simplifying the expression:

lim(x->0) |3 * x * k / (k + 1)| = |3x|

The ratio test states that if the limit of the absolute value of the ratio is less than 1, the series converges. In this case, |3x| < 1 for x < 1/3.

Request Answer ? m m (20%) Problem 1: You have made someone very angry! After a brief struggle, three thugs manage to get you shackled to a heavy steel ball and throw you into the river. You sink to a depth of 9.8 m. Because of the hydrostatic pressure at that depth your body is squished to 89 % of its original volume. The entire process of your being tossed into the river results in the release of 135 J of heat from your body. Fortunately, you manage to escape and swim to shore. Then you begin to wonder about the change in your internal energy as a result of the entire fiasco. A 50% Part (a) Determine the total pressure on your body, in pascals, when you were at the depth of 9.8 m. Take the atmospheric pressure to be 1.01 X 10 Pa.
