Find dy/dx by implicit differentiation and evaluate the
derivative at the given point
x^3 + y^3 = 16xy - 3 at point (8,5)

Answers

dy/dx = (3x^2 - 16y) / (16x - 3y^2)

At the point (8, 5), dy/dx = -43 / 67.

To find dy/dx by implicit differentiation, we differentiate both sides of the equation x^3 + y^3 = 16xy - 3 with respect to x, treating y as a function of x.

Differentiating x^3 with respect to x gives 3x^2. Differentiating y^3 with respect to x requires the chain rule, resulting in 3y^2 * dy/dx. Differentiating 16xy with respect to x gives 16y + 16x * dy/dx. The constant term -3 differentiates to 0.

Combining these terms, we have 3x^2 + 3y^2 * dy/dx = 16y + 16x * dy/dx.

Next, we isolate dy/dx by moving the terms involving dy/dx to one side of the equation and the other terms to the other side. We get 3x^2 - 16x * dy/dx = 16y - 3y^2 * dy/dx.

Now, we can factor out dy/dx from the left side and y from the right side. This gives dy/dx * (3x^2 + 3y^2) = 16y - 16x.

Finally, we divide both sides by (3x^2 + 3y^2) to solve for dy/dx:

dy/dx = (16y - 16x) / (3x^2 + 3y^2).

Substituting the coordinates of the given point (8, 5) into the expression for dy/dx, we find dy/dx = (16(5) - 16(8)) / (3(8)^2 + 3(5)^2) = -43 / 67.

Therefore, at the point (8, 5), the derivative dy/dx is equal to -43 / 67.

The derivatives are R'(t) = 2i + 6tj + 9t²k and R''(t) = 6j + 18tk.

To find the derivative of R(t), we differentiate each component of the vector separately:

R(t) = 2ti + 3t²j + 3t³k

Taking the derivative of each component:

R'(t) = (d/dt)(2ti) + (d/dt)(3t²j) + (d/dt)(3t³k)

= 2i + (d/dt)(3t²)j + (d/dt)(3t³)k

To find the second derivative of R(t), we differentiate each component of R'(t):

R''(t) = (d/dt)(2i) + (d/dt)(6tj) + (d/dt)(9t²k)

= 0i + 6j + (d/dt)(9t²)k

Solve by method of Laplace transform
with equation: y'' + y = 4δ(t − 2π)
where y(0) = 1, y'(0) = 0

Answers

The solution to the given differential equation is: y(t) = 4δ(t - 2π) + 2cos(t). To solve the differential equation using the Laplace transform, we first take the Laplace transform of both sides of the equation.

The Laplace transform of the second derivative y''(t) can be expressed as s^2Y(s) - sy(0) - y'(0), where Y(s) is the Laplace transform of y(t). Similarly, the Laplace transform of the delta function δ(t - 2π) is e^(-2πs).

Applying the Laplace transform to the differential equation, we get:

s^2Y(s) - s(1) - 0 + Y(s) = 4e^(-2πs)

Simplifying the equation, we have:

s^2Y(s) + Y(s) - s = 4e^(-2πs) + s

Now, we solve for Y(s):

Y(s)(s^2 + 1) = 4e^(-2πs) + s + s(1)

Y(s)(s^2 + 1) = 4e^(-2πs) + 2s

Y(s) = (4e^(-2πs) + 2s) / (s^2 + 1)

To find y(t), we need to take the inverse Laplace transform of Y(s). Since the inverse Laplace transform of e^(-as) is δ(t - a), we can rewrite the equation as:

Y(s) = 4e^(-2πs) / (s^2 + 1) + 2s / (s^2 + 1)

Taking the inverse Laplace transform of each term, we get:

y(t) = 4δ(t - 2π) + 2cos(t)

Note that the initial conditions y(0) = 1 and y'(0) = 0 are automatically satisfied by the solution.

Randi went to Lowe’s to buy wall-to-wall carpeting. She needs 109.41 square yards for downstairs, 30.41 square yards for the halls, and 160.51 square yards for the bedrooms upstairs. Randi chose a shag carpet that costs $13.60 per square yard. She ordered foam padding at $3.10 per square yard. The carpet installers quoted Randi a labor charge of $3.75 per square yard.

What will the total job cost Randi? (Round your answer to the nearest cent.)

Answers

Rounded to the nearest cent, the total job cost for Randi is $6,138.99.

To calculate the total cost for Randi's carpeting job, we need to consider the cost of the carpet, foam padding, and labor.

1. Carpet cost:

The total square yards of carpet needed is:

Downstairs: 109.41 square yards

Halls: 30.41 square yards

Upstairs bedrooms: 160.51 square yards

The total square yards of carpet required is the sum of these areas:

109.41 + 30.41 + 160.51 = 300.33 square yards

The cost of the carpet per square yard is $13.60.

Therefore, the cost of the carpet is:

300.33 * $13.60 = $4,080.19

2. Foam padding cost:

The total square yards of foam padding needed is the same as the carpet area: 300.33 square yards.

The cost of the foam padding per square yard is $3.10.

Therefore, the cost of the foam padding is:

300.33 * $3.10 = $930.81

3. Labor cost:

The labor cost is quoted at $3.75 per square yard.

Therefore, the labor cost is:

300.33 * $3.75 = $1,126.99

4. Total job cost:

The total cost is the sum of the carpet cost, foam padding cost, and labor cost:

$4,080.19 + $930.81 + $1,126.99 = $6,138.99

Answers

The derivative or antiderivative of the given functions are obtained using quotient rule of differentiation.

a) To find the derivative of the given function dx/ (x^2 + 4x - 1), apply the quotient rule of differentiation.

[tex]df/dx = (g(x)f'(x) - f(x)g'(x)) / (g(x))^2[/tex]

Here, g(x) = x^2 + 4x - 1 and f(x) = 1.

Using the product rule,dg/dx = 2x + 4 and hence g'(x) = 2x + 4

Using the quotient rule,

[tex]d/dx (1/g(x)) = -g'(x) / (g(x))^2\\df/dx = [(x^2 + 4x - 1)(0) - 1(2x + 4)] / (x^2 + 4x - 1)^2\\= -(2x + 4) / (x^2 + 4x - 1)^2[/tex]

b) To find the antiderivative of the given function ∫dx/ (x^2 + 4x - 1), apply the substitution method.

Substituting

[tex]u = x^2 + 4x - 1 \\du = (2x + 4)dx.[/tex]

Now, the integral becomes ∫du / u²

Taking the antiderivative, we get

[tex]-1/u + C = -1 / (x^2 + 4x - 1) + C,[/tex]

where C is the constant of integration.

c) To find the derivative of the given function d/dx (x+5)(x-2),

apply the product rule of differentiation.

[tex]d/dx [(x+5)(x-2)] = (x+5)d/dx (x-2) + (x-2)d/dx (x+5)\\= (x+5)(1) + (x-2)(1)\\= 2x + 3[/tex]

d) To find the antiderivative of the given function ∫(x+5)(x-2)dx, apply the distributive property of integration.

[tex]∫(x+5)(x-2)dx= ∫(x^2 + 3x - 10)dx\\= (x^3/3) + (3x^2/2) - 10x + C,[/tex]

3. Find the local maxima of A. List your answers as points in the form (a,b).
4. Find the local minima of A. List your answers as points in the form (a,b).

Answers

A(x) = x√(x + 2) is increasing on the interval (-2/3, ∞), decreasing on (-∞, -2/3), has a local maximum at (-2/3, -2√(2/3)), no local minima, is concave upward on (-∞, -2/3), and concave downward on (-2/3, ∞).

The interval(s) on which A(x) is increasing can be determined by finding the derivative of A(x) and identifying where it is positive. Taking the derivative of A(x), we get A'(x) = (3x + 2) / (2√(x + 2)). To find where A'(x) > 0, we set the numerator greater than zero and solve for x. Therefore, the interval on which A(x) is increasing is (-2/3, ∞).

Similarly, to find the interval(s) on which A(x) is decreasing, we look for where the derivative A'(x) is negative. Setting the numerator of A'(x) less than zero, we solve for x and find the interval on which A(x) is decreasing as (-∞, -2/3).

To find the local maxima of A(x), we need to locate the critical points by setting A'(x) equal to zero. Solving (3x + 2) / (2√(x + 2)) = 0, we find a critical point at x = -2/3. Evaluating A(-2/3), we get the local maximum point as (-2/3, -2√(2/3)).

To find the local minima, we examine the endpoints of the interval. As x approaches -∞ or ∞, A(x) approaches -∞, indicating there are no local minima.

To determine the intervals on which A(x) is concave upward, we find the second derivative A''(x). Taking the derivative of A'(x), we have A''(x) = (3√(x + 2) - (3x + 2) / (4(x + 2)^(3/2)). Setting A''(x) > 0, we solve for x and find the intervals of concave upward as (-∞, -2/3).

Finally, the intervals on which A(x) is concave downward are determined by A''(x) < 0. By solving the inequality A''(x) < 0, we find the interval of concave downward as (-2/3, ∞).

Answers

True. If δ = ε will work for the formal definition of the limit, then so will δ = ε/4. The δ value that satisfies the condition of the limit, even with a smaller range, conclude that if δ = ε works, then so will δ = ε/4.

The formal definition of a limit involves the concept of "δ-ε" proofs, where δ represents a small positive distance around a point and ε represents a small positive distance around the limit. In these proofs, the goal is to find a δ value such that whenever the input is within δ distance of the point, the output is within ε distance of the limit.

If δ = ε is valid for the formal definition of the limit, it means that for any given ε, there exists a δ such that whenever the input is within δ distance of the point, the output is within ε distance of the limit.

Now, if we consider δ = ε/4, it means that we are taking a smaller distance, one-fourth of the original ε, around the limit. In other words, we are tightening the requirement for the output to be within a smaller range.

Since we are still able to find a δ value that satisfies the condition of the limit, even with a smaller range, we can conclude that if δ = ε works, then so will δ = ε/4.

Find the volume of the solid generated by revolving the regions bounded by the lines and curves y=e^(-1/3)x, y=0, x=0 and x=3 about the x-axis.

Answers

The volume of the solid generated by revolving the region bounded by the lines and curves y = e^(-1/3)x, y = 0, x = 0, and x = 3 about the x-axis is 6π/e - 6π (cubic units).

To find the volume of the solid generated by revolving the given region about the x-axis, we can use the method of cylindrical shells.

The region bounded by the lines and curves y = e^(-1/3)x, y = 0, x = 0, and x = 3 forms a triangle. Let's denote this triangle as T.

To calculate the volume, we'll integrate the circumference of each cylindrical shell multiplied by its height.

The height of each shell will be the difference between the upper and lower boundaries of the region, which is given by the curve y = e^(-1/3)x.

The radius of each shell will be the distance from the x-axis to a given x-value.

Let's set up the integral to calculate the volume:

V = ∫[a,b] 2πx * (e^(-1/3)x - 0) dx,

where [a,b] represents the interval of x-values that bounds the region T (in this case, [0,3]).

V = 2π * ∫[0,3] x * e^(-1/3)x dx.

To solve this integral, we can use integration by substitution. Let u = -1/3x, which implies du = -1/3 dx.

When x = 0, u = -1/3(0) = 0, and when x = 3, u = -1/3(3) = -1.

Substituting the values, the integral becomes:

V = 2π * ∫[0,-1] (-(3u)) * e^u du.

V = -6π * ∫[0,-1] u * e^u du.

Now, we can integrate by parts. Let's set u = u and dv = e^u du, then du = du and v = e^u.

Using the formula for integration by parts, ∫u * dv = uv - ∫v * du, we get:

V = -6π * [(uv - ∫v * du)] evaluated from 0 to -1.

V = -6π * [(0 - 0) - ∫[0,-1] e^u du].

V = -6π * [-∫[0,-1] e^u du].

V = 6π * ∫[0,-1] e^u du.

V = 6π * (e^u) evaluated from 0 to -1.

V = 6π * (e^(-1) - e^0).

V = 6π * (1/e - 1).

Finally, we can simplify:

V = 6π/e - 6π.

Therefore, the volume of the solid generated by revolving the region bounded by the lines and curves y = e^(-1/3)x, y = 0, x = 0, and x = 3 about the x-axis is 6π/e - 6π (cubic units).

Solving these recurrence relations allows us to find the specific values of \(a_n\) in terms of \(a_0\), \(a_1\), and \(a_2\), which are determined by the initial conditions.

Next, we determine the specific form of the power series solution by substituting the obtained coefficients back into the power series representation [tex]\(y(x)=\sum_{n=0}^{\infty} a_{n} x^{n}\)[/tex].

Answers

The selling price refers to the amount of money at which a product or service is offered for purchase. It represents the value that the seller expects to receive in exchange for the item being sold.

If  f(x) = 2x², and g(x) = 4x - 1, we have to find f(g(x)). The given value of g(x) = 4x - 1.To find f(g(x)), we need to replace x in f(x) with the given value of g(x) and then simplify it. We have;

f(g(x)) = f(4x - 1) = 2(4x - 1)²

.= 2(16x² - 8x + 1)

= 32x² - 16x + 2 Therefore,

f(g(x)) = 32x² - 16x + 2.(5)  

A hotdog vendor has fixed costs of $160 per day to operate, plus a variable cost of $1 per hotdog sold. He earns $2 per hotdog sold. To find the break-even point, we need to equate the cost of producing hotdogs to the revenue earned by selling them. Therefore, let's assume he sells x hotdogs in a day, then his cost of selling x hotdogs would be;

C(x) = $160 + $1x = $160 + $x

And his revenue would be; R(x) = $2x

Thus, the break-even point is when the cost of selling x hotdogs is equal to the revenue earned by selling them. Hence, we have the equation;

C(x) = R(x) $160 + $x = $2x $160 = $x x = 80

Therefore, the hotdog vendor needs to sell at least 80 hotdogs a day to break even.

If the equation of the tangent plane to x2+y2−268z2=0 at (1,1,√1/134​) is x+αy+βz+γ=0, then α+β+γ=___

Answers

The value of α + β + γ is 151/67 - 8√1/67.

Given, the equation of the tangent plane to x² + y² - 268z² = 0 at (1,1,√1/134​) is x + αy + βz + γ = 0.

We have to determine α + β + γ.

To determine the value of α + β + γ, we first need to determine the equation of the tangent plane.

Let z = f(x,y) = x² + y² - 268z² be the equation of the given surface.

We differentiate the equation of the surface with respect to x and y, respectively, to obtain the partial derivatives of f as follows.f₁(x,y) = ∂f/∂x = 2xf₂(x,y) = ∂f/∂y = 2y

To determine the equation of the tangent plane at (x₁, y₁, z₁), we use the following equation:

                                               P(x,y,z) = f(x₁, y₁, z₁) + f₁(x₁, y₁)(x-x₁) + f₂(x₁, y₁)(y-y₁) - (z - z₁) = 0.

Substituting x₁ = 1, y₁ = 1, z₁ = √1/134 in the above equation, we get

                                         P(x,y,z) = (1)² + (1)² - 268(√1/134)² + 2(1)(x-1) + 2(1)(y-1) - (z - √1/134) = 0

Simplifying the above equation, we get

                                                  x + y - 8√1/67 z + 9/67 = 0

Comparing the above equation with the given equation of the tangent plane, we have

                                                    α = 1β = 1-8√1/67 = -8√1/67γ = 9/67

Therefore, α + β + γ = 1 + 1 - 8√1/67 + 9/67= 2 - 8√1/67 + 9/67= 151/67 - 8√1/67

Hence, the detail ans for the given problem is: The value of α + β + γ is 151/67 - 8√1/67.

Given function:

limx→5​f(x)=0,

limx→5​g(x)=0, and

limx→5​g(z)f(z)​=0.

We need to find two differentiable functions f and g that satisfy the above constraints using L'Hôpital's Rule.

First, let's consider the function f(x) such that

limx→5​f(x)=0.

Now, let's consider the function g(x) such that

limx→5​g(x)=0.

The function g(z)f(z) will become 0, as we have

limx→5​g(z)f(z)​=0.

Now, let us apply L'Hôpital's rule to find a suitable function:

limx→5​f(x)=0

⇒0/0

⇒ limx→5​(f(x)/1)

Using L'Hôpital's Rule, we get

limx→5​(f(x)/1)

=limx→5​​f′(x)1

=0

Therefore, f(x) can be f(x) = x − 5.

Now, let us apply L'Hôpital's rule to find a suitable function:

limx→5​g(x)=0

⇒0/0

⇒ limx→5​(g(x)/1)

Using L'Hôpital's Rule, we get

Use undetermined coefficients to find the particular solution to

yp(t)=

Answers

Using the method of undetermined coefficients, the particular solution yp(t) for the given second-order linear homogeneous differential equation is yp(t) = At^2 + Bt + C, where A, B, and C are constants to be determined.

To find the particular solution yp(t), we assume it has the form yp(t) = At^2 + Bt + C, where A, B, and C are constants. Since the right-hand side of the equation is a polynomial of degree 2, we choose a particular solution of the same form.

Differentiating yp(t) twice, we obtain yp''(t) = 2A, and yp'(t) = 2At + B. Substituting these derivatives into the differential equation, we have:

2A + 5(2At + B) + 3(At^2 + Bt + C) = 4t^2 + 8t + 4.

Expanding and grouping the terms, we have:

(3A)t^2 + (5B + 2A)t + (2A + 5B + 3C) = 4t^2 + 8t + 4.

Equating the coefficients of like terms, we get the following equations:

3A = 4, (5B + 2A) = 8, and (2A + 5B + 3C) = 4.

Solving these equations, we find A = 4/3, B = 4/5, and C = -2/15. Therefore, the particular solution is yp(t) = (4/3)t^2 + (4/5)t - 2/15.

Find the inverse of each function. f(x)=−5x+2

Answers

The inverse of the function f(x) = -5x + 2 is given by f^(-1)(x) = (x - 2)/(-5).

To find the inverse of a function, we need to interchange the roles of x and y and solve for y. Let's start by replacing f(x) with y in the given function: y = -5x + 2. Now, we'll swap x and y: x = -5y + 2. Next, we solve this equation for y. Rearranging the terms, we get: 5y = 2 - x. Finally, we divide both sides by 5 to isolate y: y = (2 - x)/5. Hence, the inverse function is f^(-1)(x) = (x - 2)/(-5).

The inverse function (f^(-1)(x)) takes an input x and yields the original input for f(x). When we substitute f^(-1)(x) into f(x), we should obtain x. Let's verify this by substituting (x - 2)/(-5) into f(x): f((x - 2)/(-5)) = -5 * ((x - 2)/(-5)) + 2. Simplifying this expression, we get (-1) * (x - 2) + 2 = -x + 2 + 2 = -x + 4. As expected, the result is x, confirming that (x - 2)/(-5) is indeed the inverse of f(x) = -5x + 2.

Find the average price of the stock over the first six years. The average price of the stock is 5 (Round to the nearest cent as needed).

Answers

The average price of the stock over the first six years is $52.

The given function is [tex]S(t)=44+8e^{0.02t}[/tex].

Where, t is the time (in years) since the stock was purchased

We want to find the average price of the stock over the first six years.

To find the average price we will need to find the 6-year sum of the stock price and divide it by 6.

To find the 6-year sum of the stock price, we will need to evaluate the function at t = 0, t = 1, t = 2, t = 3, t = 4, and t = 5 and sum up the results.

Therefore,

S(0)=44+[tex]8e^{-0.02(0)}[/tex] = 44+8 = 52

S(1)=44+[tex]8e^{-0.02(1)}[/tex]= 44+7.982 = 51.982

S(2)=44+[tex]8e^{-0.02(2)}[/tex] = 44+7.965 = 51.965

S(3)=44+[tex]8e^{-0.02(3)}[/tex] = 44+7.949 = 51.949

S(4)=44+8[tex]e^{-0.02(4)}[/tex] = 44+7.933 = 51.933

S(5)=44+[tex]8e^{-0.02(5)}[/tex] = 44+7.916 = 51.916

The 6-year sum of the stock price is 51 + 51.982 + 51.965 + 51.949 + 51.933 + 51.916 = 309.715.

The average price of the stock over the first six years is 309.715/6 = 51.619167 ≈ 52

There are two types of improper integrals. Write two improper integrals, one of each type, and state why each is improper.


Write, but do not evaluate, the partial fractions decomposition of (9x^2 – 4)/ (x−9)^2(x^2−9)(x2+9)

Answers

Improper integrals: Improper integrals are integrals with an infinite region of integration or integrands that have an infinite discontinuity within their limits.

Improper integrals are classified into two types: Type I and Type II.

Let's see both of them below:

Type I Improper Integrals:

If the limit, as b approaches a from the right-hand side, of the integral of f(x) from a to b does not exist, then the Type I improper integral is represented by ∫a to ∞ f(x)dx, or∫−∞ to a f(x)dx.

Because the integral of f(x) from a to b has no limit as b approaches a from the right-hand side, this occurs.

Type II Improper Integrals: If f(x) has an infinite discontinuity in the interval (a,b) or at b, then the Type II improper integral is represented by∫a to b f(x)dx = lim h→b- ∫a to h f(x)dx or ∫b to ∞ f(x)dx = lim n→∞ ∫b to n f(x)dx. This occurs since the interval of integration contains an infinite discontinuity.

In other words, if f(x) has an infinite discontinuity in (a,b) or at b, the integral of f(x) from a to b, or from b to infinity, does not converge.

Partial fractions decomposition of (9x²-4)/[(x-9)²(x²-9)(x²+9)] can be given as shown below:

For a given rational function whose denominator is a product of quadratic factors, partial fractions are a method of reducing it to a sum of simpler fractions. In order to locate the coefficients A, B, C, D, E, and F in partial fraction decomposition of the given rational function, follow the steps below.

The denominators of partial fraction can be shown as follows;

[tex]$$\frac{9{x}^{2}-4}{\left(x-9\right)^{2}\left(x^{2}-9\right)\left(x^{2}+9\right)}=\frac{A}{x-9}+\frac{B}{\left(x-9\right)^{2}}+\frac{C}{x+3}+\frac{D}{x-3}+\frac{E}{x^{2}+9}+\frac{F}{x+3}$$[/tex]

Multiply both sides of the equation by the common denominator, which is; (x - 9)²(x + 3)(x - 3)(x² + 9)

Answers

The formula for the density of the cone is rho(x, y, z) = 10 - ((10 - 8)/4) * z.  The total mass of the cone can be calculated by integrating the density function over the region defined by the cone.

(a) The density of the cone varies linearly with the distance from the xy-plane. Given that the density at the bottom point is 10 g/cm^3 and the density at the top layer is 8 g/cm^3, we can express the density as a function of z using the equation of a straight line. The formula for the density of the cone is rho(x, y, z) = 10 - ((10 - 8)/4) * z.

(b) To calculate the total mass of the cone, we need to integrate the density function rho(x, y, z) over the region defined by the cone. Since the region is not explicitly defined, the integration will depend on the coordinate system being used. Without the specific region, it is not possible to provide a numerical value for the total mass.

(c) The average density of the cone is not 9 g/cm^3 because the density is not uniformly distributed throughout the cone. It varies linearly with the distance from the xy-plane, becoming denser as we move towards the bottom of the cone. Therefore, the average density will be less than the density at the bottom and greater than the density at the top. The actual average density can be calculated by integrating the density function over the region and dividing by the volume of the region.

Include the completed code for all parts o this question in a file called kachi.py. NOTE: To implement encapsulation, all of the instance variables/fields should be considered private.Planet Kachi has two kinds of inhabitants, Dachinaths and the more spiritual Kachinaths. All Kachi inhabitants are born as Dachinaths who aspire to be Kachinaths through austere living and following a mentor Kachinath. Once a Dachinath has become a full Kachinath, they have unlimited power in their chosen power category. Until then, they have a percentage of power based on their number of years of austere life. Design a class Kach inath for Question 2 (a) and a subclass Dachinath for Question 2 (b), with a tester function as described in Question 2 (c). Question 2 (a) Design and implement a class called Kachinath with the following private instance variables: - KID is the given unique identifier for a Kachinath (default value " 000 ") - kName is the name of the Kachinath (default value "unknown") - kPowerCategory is the category of power that the Kachinath has (flowing, light, changing forms, etc) (default value "unknown") Also, include the following methods: - constructor to create a Kachinath object. - accessor methods to access each of the instance variables - a method called computePowerLevel which returns 1.0 as the amount of power that a Kachinath has (meaning100%of power) - special str _ method to return the ID, name, power category and the computed power level of the Question 2 (b) Extend the class defined in Question 2 (a) to include a subclass called Dachinath which has additional private instance variables as follows: - kinife is the number of years of austere life that the Dachinath has so far (default value 0.0) - KFOllowed is the name of the Kachinath that the Dachinath is following as a mentor (default value "unknown") Also, include the following methods: - constructor to create a Dachinath object - accessor methods to access each of the additional instance variables - a method called computePowerLevel which overrides the computePowerLevel method of the superclass to compute the Dachinath's power level as half of a percent for every year of austere life, to a maximum of99%(0.99)- special str _ method to use the super class's _ str _ method to return the ID, name, power category and computed power level, and then concatenate the number of years of austere life and the name of the Kachinath that the Dachinath is following, with appropriate descriptive labels (see sample output below Question 2 (c)) Write a tester program (ma in function) to test both the superclass and subclass by - creating 2 superclass objects and 2 subclass objects using the following data: Superclass object data '1111', 'Kachilightsun', 'Light' '2222', 'Kachiflowwater', 'Flowing' Subclass object data '3232', 'Zaxandachi', 'Light', 210, 'Kachilightsun' '2323', 'Xaphandachi', 'Flowing', 120, 'Kachiflowwater' - printing both the superclass objects using the special method str with appropriate formatting as shown in the sample output - printing both the subclass objects using the special method str with appropriate formatting as shown in the sample output Sample output would be: ID: 1111 Name: Kachilightsun Power Category: Light Power Level:1.0ID: 2222 Name: Kachiflowwater Power Category: Flowing Power Level:1.0ID: 3232 Name: Zaxandachi Power Category: Light Power Level:0.99Austere Life: 210 years Kachinath Followed: Kachilightsun ID: 2323 Name: Xaphandachi Power Category: Flowing Power Level:0.6Austere Iife: 120 years Kachinath Followed: Kachiflowwater A physical system in resonance[Consider a situation in which any physical system enters resonance.
