Step-by-step explanation:

the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3

To write the system of ordinary differential equations (ODEs) for the transition probabilities Pᵢⱼ(t) of the given continuous-time Markov chain, we need to consider the rate at which the system transitions between different states.

Let Pᵢⱼ(t) represent the probability that the Markov chain is in state j at time t, given that it started in state i at time 0.

The ODEs for the transition probabilities can be written as follows:

dP₁₂(t)/dt = q₁₂ * P₁(t) - q₂₁ * P₂(t)

dP₁₃(t)/dt = q₁₃ * P₁(t) - q₃₁ * P₃(t)

dP₂₁(t)/dt = q₂₁ * P₂(t) - q₁₂ * P₁(t)

dP₂₃(t)/dt = q₂₃ * P₂(t) - q₃₂ * P₃(t)

dP₃₁(t)/dt = q₃₁ * P₃(t) - q₁₃ * P₁(t)

dP₃₂(t)/dt = q₃₂ * P₃(t) - q₂₃ * P₂(t)

where P₁(t), P₂(t), and P₃(t) represent the probabilities of being in states 1, 2, and 3 at time t, respectively.

Now, let's consider the second part of the question: Suppose that the initial state is 1. We want to find the probability that after the first transition, the process X(t) enters state 2.

To calculate this probability, we need to find the transition rate from state 1 to state 2 (q₁₂) and normalize it by the total rate of leaving state 1.

The total rate of leaving state 1 can be calculated as the sum of the rates to transition from state 1 to other states:

total_rate = q₁₂ + q₁₃

Therefore, the probability of transitioning from state 1 to state 2 after the first transition can be calculated as:

P(X(t) enters state 2 after the first transition | X(0) = 1) = q₁₂ / total_rate

In this case, the transition rate q₁₂ is 1, and the total rate q₁₂ + q₁₃ is 1 + 2 = 3.

Therefore, the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3

The statement "Feline Flavor has a lower unit price of $1.30/pound" is true. Option A is correct.

To compare the unit prices, we need to divide the price of each bag by its weight in pounds.

For Feline Flavor, the unit price is:

$20.80 ÷ 16 pounds = $1.30/pound

For Kitty Kibbles, the unit price is:

$11.20 ÷ 8 pounds = $1.40/pound

The volume of the object is 11058.6 .To find the volume of the object described, we can use the method of cross-sectional areas.

Since every cross section perpendicular to the y-axis is a semi-circle, we can find the area of each semi-circle and integrate it along the y-axis to obtain the volume.

The region bounded by the curves x = -y^2 + 14y + 15 and x = y^2 - 28y + 211 represents the base of the object. To determine the limits of integration, we need to find the y-values where the two curves intersect.

Setting the equations equal to each other, we have:

-y^2 + 14y + 15 = y^2 - 28y + 211

Simplifying, we get:

2y^2 - 42y + 196 = 0

Dividing by 2, we obtain:

y^2 - 21y + 98 = 0

Factoring, we find:

(y - 7)(y - 14) = 0

So the curves intersect at y = 7 and y = 14.

Now, let's calculate the area of each semi-circle. The radius of each semi-circle is given by the difference between the x-values of the two curves. Thus, the radius can be expressed as:

radius = (y^2 - 28y + 211) - (-y^2 + 14y + 15)

= 2y^2 - 42y + 196

The area of a semi-circle is given by A = (1/2)πr^2. Therefore, the area of each semi-circle is:

A(y) = (1/2)π(2y^2 - 42y + 196)^2

To find the volume, we integrate the area function A(y) with respect to y over the interval [7, 14]:

V = ∫[7,14] A(y) dy

= ∫[7,14] (1/2)π(2y^2 - 42y + 196)^2 dy

Evaluating this integral will give us the volume of the object.

By following these steps, you can calculate the volume of the object based on the given description.

The time response of the system is given by the equation:
u(t) = A*e^(-25t)*cos(5√7t) + B*e^(-25t)*sin(5√7t)
where A and B are constants determined by the initial conditions.

The given differential equation that models the voltage across a capacitor in the electric circuit is:

d^2u/dt^2 + (L/R)(du/dt) + (1/LC)u = (1/LC)24

To find the time response of this system, we can use different methods such as the characteristic equation method and Laplace transform method.

Let's go through each method step by step:

1. Characteristic equation method:
To find the characteristic equation, we assume the solution of the differential equation to be of the form u(t) = e^(st). Substituting this into the differential equation, we get:

s^2 + (L/R)s + (1/LC) = 0

Now, we solve this quadratic equation to find the values of s.

Plugging in the values of L, R, and C from the given information, we get:

s^2 + 50s + 50000 = 0

Solving this quadratic equation, we find two roots:

s = -25 + 5√7i and s = -25 - 5√7i

The time response of the system can be expressed as:

u(t) = A*e^(-25t)*cos(5√7t) + B*e^(-25t)*sin(5√7t)

where A and B are constants determined by the initial conditions.

2. Laplace transform method:
Taking the Laplace transform of the given differential equation, we get:

s^2U(s) + (L/R)sU(s) + (1/LC)U(s) = (1/LC)*24/s

Now, solving for U(s), we have:

U(s) = 24/(s^2 + (L/R)s + (1/LC))

Using partial fraction decomposition, we can express U(s) as:

U(s) = A/(s - (-25 + 5√7i)) + B/(s - (-25 - 5√7i))

Taking the inverse Laplace transform of U(s),

we get the time response of the system as:

u(t) = A*e^(-25t)*cos(5√7t) + B*e^(-25t)*sin(5√7t)

Again, A and B are constants determined by the initial conditions.

So, the time response of the system is given by the equation:

u(t) = A*e^(-25t)*cos(5√7t) + B*e^(-25t)*sin(5√7t)

where A and B are constants determined by the initial conditions.

With these values, the gradient vector of f at (2,3) can be found by putting x=2 and y=3 in the formula of gradient vector which is:  [-12, -6]

If f(x,y)

fx(2,3) = fy(2,3) = 36 - 6x² - y²,

then the function of f can be written as

f(x,y) = 36 - 6x² - y².

Now, f(2,3) means we need to find the value of f when x=2 and y=3.

Therefore,

f(2,3) = 36 - 6(2)² - 3²= 36 - 6(4) - 9 = 3f(x,y)

and f(x,y) are given by the formula

f(x,y) = 36 - 6x² - y².

As per the question,

fx(2,3) = fy(2,3) = 36 - 6x² - y²fx(2,3)

means we need to find the partial derivative of f with respect to x when x=2 and y=3.

So, f,x(2,3) = -12fy(2,3) means we need to find the partial derivative of f with respect to y when x=2 and y=3.

Therefore, f,y(2,3) = -6

With these values, the gradient vector of f at (2,3) can be found by putting x=2 and y=3 in the formula of gradient vector which is:

grad f(2,3) = [f,x(2,3), f,y(2,3)] = [-12, -6]

Answer:

The diver's velocity during the first 2 sec of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.

Given data: Initial velocity, u = 0 ft/sec

Acceleration, a = g = 32.2 ft/sec²

The maximum rate of fall, vmax = 80 mph

Time, t = 2 seconds

Air resistance constant, Ar = 0.2

We are supposed to determine the sky diver's velocity during the first 2 seconds of fall using the modified Euler method.

The governing equation for the velocity of the skydiver is given by the following:

ma = -m * g + k * v²

where, m = mass of the skydive

r, g = acceleration due to gravity, k = air resistance constant, and v = velocity of the skydiver.

The equation can be written as,

v' = -g + (k / m) * v²

Here, v' = dv/dt = acceleration

Hence, the modified Euler's formula for the velocity can be written as

v1 = v0 + h * v'0.5 * (v'0 + v'1)

where, v0 = 0 ft/sec, h = 2 sec, and v'0 = -g + (k / m) * v0² = -g = -32.2 ft/sec²

As the initial velocity of the skydiver is zero, we can write

v1 = 0 + 2 * (-32.2 + (0.2 / 68.956) * 0²)0.5 * (-32.2 + (-32.2 + (0.2 / 68.956) * 0.5² * (-32.2 + (-32.2 + (0.2 / 68.956) * 0²)))

v1 = 62.732 mph

Therefore, the skydiver's velocity during the first 2 seconds of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.
