The steady-state solution of the heat conduction equation refers to the temperature distribution that remains constant over time. This occurs when the heat flow into a system is balanced by the heat flow out of the system.

To find the steady-state solution of the heat conduction equation, follow these steps:

1. Set up the heat conduction equation: The heat conduction equation describes how heat flows through a medium and is typically given by the formula:

  q = -k * A * dT/dx,

  where q represents the heat flow, k is the thermal conductivity of the material, A is the cross-sectional area through which heat flows, and dT/dx is the temperature gradient in the direction of heat flow.

2. Assume steady-state conditions: In the steady-state, the temperature does not change with time, which means dT/dt = 0.

3. Simplify the heat conduction equation: Since dT/dt = 0, the equation becomes:

  q = -k * A * dT/dx = 0.

4. Apply boundary conditions: Boundary conditions specify the temperature at certain points or surfaces. These conditions are essential to solve the equation. For example, you might be given the temperature at two ends of a rod or the temperature at the surface of an object.

5. Solve for the steady-state temperature distribution: Depending on the specific problem, you may need to solve the heat conduction equation analytically or numerically. Analytical solutions involve techniques like separation of variables or Fourier series expansion. Numerical methods, such as finite difference or finite element methods, can be used to approximate the solution.

It's important to note that the exact method for solving the heat conduction equation depends on the specific problem and the boundary conditions given. However, the general approach is to set up the heat conduction equation, assume steady-state conditions, simplify the equation, apply the boundary conditions, and solve for the steady-state temperature distribution.

Answer:

The bicycle will be worth less than 1000 after 4 years.

Step-by-step explanation:

From the proportional relationship, machine will package 120 boxes in 2 minutes.

 Given points on the graph are,

(0, 0), (2, 120), (4, 240), (6, 360), (8, 480)

Here, x-values represent time in minutes and y-values represent the number of boxes packed.

Since, x and y show the proportional relationship,

Expression showing the relationship will be → y ∝ x

Or y = kx

Here, k is a proportionality constant.

k = \(\frac{y}{x}\)

From the points given, we choose one point (2, 120).

k = \(\frac{120}{2}\)

k = 60

Therefore, equation will be,

60 = \(\frac{y}{x}\)

y = 60x

For x = 2 minutes,

y = 60×2

y = 120 boxes

Hence the answer is, 120 boxes the machine will package in 2 minutes.

The statement holds true for the base case and it holds true for any k=n assuming it holds true for k=n, we can conclude that the statement holds true for all positive integer values of k. Hence, if we remove the root of a \($\mathrm{k}^{\text {th }}$\) order binomial tree, it results in k binomial trees of the smaller orders.

The statement to be proven is: "If we remove the root of a \($\mathrm{k}^{\text {th }}$\) order binomial tree, it results in \($\mathrm{k}$\) binomial trees of the smaller orders."

We will prove this statement by mathematical induction.

Base case k=1 :

Inductive step:

Suppose the statement holds true for some \($\mathbf{k}=\mathbf{n}$\), i.e., if we remove the root of an \($\mathbf{n}^{\text {th }}$\) order binomial tree, it results in \($\mathrm{n}$\) binomial trees of the smaller orders. We need to show that it also holds true for \($\mathbf{k}=\mathbf{n}+1$\)

using definition of mathematical induction.

Consider a \($(\mathrm{n}+1)^{\text {th }}$\) order binomial tree, which can be formed by joining two \($\mathrm{n}^{\text {th }}$\) order binomial trees. If we remove the root of this \($(\mathrm{n}+1)^{\text {th }}$\) order binomial tree, we are left with two nth order binomial trees. By the induction hypothesis, each of these \($\mathbf{n}^{\text {th }}$\) order binomial trees will result in n binomial trees of the smaller orders. Hence, the result of removing the root of the \($(n+1)^{\text {th }}$\) order binomial tree will be n + n = 2n binomial trees of the smaller orders, which implies that the statement holds true for \($\mathrm{k}=\mathrm{n}+1$\) as well.

The angles of a triangle add up to 180 degrees.

(3x+5)+(2x+17)+(2x+18)=180

add the ones alike

3x + 2x + 2x=7x

5+17+18=40

so, 7x+40=180

we need to get the variable by itself so we take away 40 first by subtracting it from both sides of the equal sign

7x=140

we take away 7 from x by dividing it- opposite of multiplication is division

x=20

Answer:

x = 20

Step-by-step explanation:

3x+5° + 2x+18° + 2x+17° = 180° (sum of interior angles in a triangle is 180°)

collect like terms

3x + 2x + 2x + 5° + 18° + 17° = 180°

7x + 40° = 180°

solving for x

x = (180 - 40)/7

x = 140/7

Here's a Python program called "Powers" that calculates the first four powers of a given number:

```python

def powers(number):

   for exponent in range(1, 5):

       result = number ** exponent

       power_list.append(result)

A) ∠ABD is a right angle.

E) m∠ABD = 90°

Step-by-step explanation:

just took the test

∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Given that,

Angle A B D is a right angle.

The right angle is a 90-degree angle.

So,

m∠ABD = 90°

Hence "∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles".

The graph of the inverse of a function is its reflection across the line y = x

Please find attached the required graph created with MS Excel

The graph of the inverse of a function is reflected over the line y = x

In order to graph the function f⁻¹, either the line y = x is drawn and the points of f⁻¹ are traced by taking equal distance from the line y = x, or the x, and y-coordinates of the f are reversed to get the coordinates of f⁻¹ as follows;

The reflection of the point (x, y) across the line y = x is (y, x)

The vertices of the graph of the function f, staring from the top are;

(5, 6), (3, -3), (-3, -5)

Therefore, we have;

The reflection of the point (5, 6) across the line y = x is (6, 5)

The reflection of the point (3, -3) across the line y = x is (-3, 3)

The reflection of the point (-3, -5) across the line y = x is (-5, -3)

20a^2+68a

Step-by-step explanation:

The question is asking for Area: a=length*width.

In this case, length= 5a+17     width=4a

You multiply 4a to 5a+17 and you get 20a^2+68a

Area of the rectangular garden is given by (20a²+68a)square feet.

" Area is defined as total space occupied by any two dimensional object enclosed in it."

Formula used

Area of a rectangle = length × width

According to the question,

Given,

Length of the rectangular garden = 5a + 17 feet

Width of the rectangular garden = 4a feet

Substitute the value in the formula we get,

Area of the rectangular garden = (5a +17) (4a)

                                                    = 20a² +68a

Hence, area of the rectangular garden is given by (20a²+68a)square feet.
