The final solution in terms of the inverse Laplace transforms:

\(ƒ(t) = L^{-1}[F(s)]\)

We have,

To solve the given ordinary differential equation (ODE) using Laplace transform, we'll follow these steps:

Step 1: Take the Laplace transform of both sides of the equation.

Step 2: Solve for the Laplace transform of the function ƒ(t).

Step 3: Take the inverse Laplace transform to obtain the solution in the time domain.

Let's go through these steps:

Step 1: Taking the Laplace transform of the ODE, we have:

L[f"(t)] + 6L[f'(t)] + 13L[f(t)] = 48L[t - 5]

Step 2: Applying the Laplace transform properties and using the initial conditions, we get:

\(s^2F(s) - sf(0) - f'(0) + 6(sF(s) - f(0)) + 13F(s) = 48(e^{-5s}/s)\)

Simplifying, we have:

\(s^2F(s) + 6sF(s) + 13F(s) - s(0) - 0 + 6sF(s) - 6(0) + 13F(s) = 48(e^{-5s}/s)\)

Combining like terms, we obtain:

\((s^2 + 6s + 13)F(s) = 48(e^{-5s}/s)\)

Step 3: Solving for F(s), we have:

\(F(s) = 48(e^{-5s}/s) / (s^2 + 6s + 13)\)

To find the inverse Laplace transform of F(s), we can use partial fraction decomposition, but the expression involves complex roots.

Therefore,

The final solution in terms of the inverse Laplace transforms:

\(ƒ(t) = L^{-1}[F(s)]\)

The code efficiently identifies prime numbers using the ancient Greek algorithm. It initializes an array, marks the multiples of each prime number as non-prime, and then prints the prime numbers.

This algorithm demonstrates a straightforward and efficient method for finding prime numbers within a given range.The ancient Greek algorithm for finding prime numbers less than or equal to a given number is implemented in the provided Python code. The algorithm follows a simple approach of marking numbers as prime or non-prime.

It starts by assuming all numbers as prime and then proceeds to mark the multiples of each prime number as non-prime. The code initializes an array where each element represents a number and marks them all as prime initially. Then, it iterates over each number from 2 to the given number, checking if it is marked as prime. If it is, the algorithm crosses out all its multiples as non-prime. Finally, it prints the numbers that remain marked as prime.

Step-by-step explanation:

The planet's a) size has virtually no effect on its structure.

The size of a planet does not affect its internal structure significantly because the same physical laws govern the formation and evolution of all planets. However, the size of a planet does have some impact on its atmosphere, gravity, and surface features.

For example, smaller planets may have weaker gravity, which makes it easier for gases to escape their atmosphere. Conversely, larger planets may have stronger gravity, which can compress their atmosphere and create more extreme weather patterns.

Overall, a planet's structure is primarily determined by its mass, composition, and magnetic field, rather than its size.

The volume of the square pyramid in terms of x is (1/3) * x^4.

The volume V of a square pyramid can be calculated using the formula:

V = (1/3) * Base Area * Height

In this case, the base of the pyramid is a square with side length x, so the base area is given by:

Base Area = x^2

The height of the pyramid is given as x^2, so substituting these values into the volume formula, we have:

V = (1/3) * x^2 * x^2

Simplifying, we get:

V = (1/3) * x^4

Therefore, the volume of the square pyramid in terms of x is (1/3) * x^4.

Their x-intercepts are different: f(x) being a polynomial might have various x-captures, while g(x) being a logarithmic capability has a solitary x-block at x = 1.

The capability f(x) = x^3 + x^2 - 2x + 3 is a polynomial capability of degree 3. Power terms with positive integer exponents and operations of addition and subtraction are included. The polynomial's degree is determined by the function's highest power of x, which is 3.

The capability g(x) = log(x) + 2 is a logarithmic capability. It includes the logarithm activity applied to x, alongside expansion. The space of f(x) is all genuine numbers since there are no limitations on x. The space of g(x) is x > 0 since logarithms are indistinct for non-positive qualities.

The scope of the two capabilities is all genuine numbers since the two polynomials and logarithmic capabilities can take any genuine worth. By solving for x and setting f(x) = 0 and g(x) = 0, respectively, the x-intercepts of f(x) and g(x) can be determined. The y-intercept of f(x) is (0, 3), as f(0) = 3, and the y-intercept of g(x) is (1, 2), as g(1) = 2.

The fact that both f(x) and g(x) have distinct domains and ranges that encompass all real numbers is their most important feature in common. Also, the two capabilities have exceptional y-blocks. However, their x-intercepts are different: f(x) being a polynomial might have various x-captures, while g(x) being a logarithmic capability has a solitary x-block at x = 1.

Slope Sales will be $-159.474 at 0 degrees Celsius, which is nonsensical to understand.

A line's steepness is determined by its slope. The "gradient overflow" is a mathematical expression for the gradient (the change in y divided by the change in x). The ratio of the vertical change (rise) between two points to the horizontal change (run) between the same two places is referred to as the slope. The slope-intercept form of an equation is used to represent each time a straight line's equation is stated as y = mx + b. The line's slope is m. b is b at the point where the y-intercept is, and (0, b). As an illustration, the equation y = 3x - 7 has a slope of 3, and its y-intercept is (0, 7).

b) To solve the recurrence relation T(n) = 3²(k-1) + 3T(3²(k-1)) for k >= 1, expand the recurrence to find a pattern and then extrapolate to the bottom level.

Let's calculate T(1), T(3), T(9), and T(27) to identify the pattern:

T(1) = 0

T(3) = 3²(3-1) + 3T(3³(3-1)) = 3² + 3T(3) = 9 + 3(0) = 9

T(9) = 3³(9-1) + 3T(3³(9-1)) = 3³ + 3T(3³) = 6561 + 3T(6561)

T(27) = 3²(27-1) + 3T(3²(27-1)) = 3³ + 3T(3²6)

We can observe that T(1) = 0, T(3) = 9, T(9) = 6561 + 3T(6561), and T(27) = 3³ + 3T(3³6).

Now, let's try to find a pattern in the values of T(1), T(3), T(9), and T(27):

T(1) = 0

T(3) = 3² + 3T(3) = 9 + 3(0) = 9

T(9) = 3³ + 3T(3³) = 6561 + 3T(6561)

T(27) = 3²6 + 3T(3²6)

From the above values, that T(3) = 3², T(9) = 3³, and T(27) = 3²6.

Based on this pattern,  generalize that T(3²) = 3²(2k) for k >= 0.

Now, let's express the formula in terms of n:

Let n = 3²k

Then, k = log base 3 of n

Therefore, T(n) = 3²(2log3(n)) = n²

c) To show that the formula in Part b, T(n) = n², is theta of nlogn, to prove that T(n) is both Big O(nlogn) and Omega(nlogn).

Big O(nlogn) proof:

We need to find a constant c and an integer N such that T(n) <= c ×nlogn for all n >= N.

Let's consider T(n) = n². choose c = 1 and N = 1.

For n >= N,

T(n) = n² <= n² ×logn (as logn >= 1 for n >= 1)

<= c × nlogn

Therefore, T(n) is Big O(nlogn).

Omega(nlogn) proof:

To find a constant c and an integer N such that T(n) >= c ×nlogn for all n >= N.

Let's consider T(n) = n². choose c = 1 and N = 1.

For n >= N,

T(n) = n >= n ×logn (as logn >= 1 for n >= 1)

>= c ×nlogn

Therefore, T(n) is Omega(nlogn).

c) The absolute value function reflected across the x axis stretched vertically by 5 units shifted left 4 units and up 6 units is y₃ = -5 | x₃ + 4 | + 6

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Since none of the 13 classmates had been given math homework between the original survey and Kelly's second survey, the sum of the values in the second data set is the same as the sum of the values in the original data set. Therefore, the change in the means can be determined without calculating the mean of either data set by considering the number of data points in each set.

Since both data sets have the same number of data points, the change in the means will be zero. This is because the mean is calculated by dividing the sum of the values by the number of data points, and since the sum of the values is the same in both data sets, the means will also be the same.

In other words, the change in the mean is calculated as follows:

Change in mean = Mean of second data set - Mean of first data set

Since none of the values in the second data set have changed, the mean of the second data set is the same as the mean of the first data set. Therefore, the change in the mean is:

Change in mean = Mean of second data set - Mean of first data set

= Mean of first data set - Mean of first data set

= 0

Thus, the change in the means between Kelly's original survey and her second survey is zero.
