The general solution of the given second-order linear ordinary differential equation is y = (c1 + c2x)e^(5x) + 22/25, where c1 and c2 are arbitrary constants.

The given differential equation is y'' - 10y' + 25y = 22. To find the general solution, we first need to find the complementary function by solving the associated homogeneous equation, which is y'' - 10y' + 25y = 0.

Assuming a solution of the form y = e^(rx), we substitute it into the homogeneous equation and obtain the characteristic equation r^2 - 10r + 25 = 0. Solving this quadratic equation, we find that r = 5 is a repeated root.

Therefore, the complementary function is of the form y_c = (c1 + c2x)e^(5x), where c1 and c2 are arbitrary constants.

Next, we find a particular solution for the non-homogeneous equation y'' - 10y' + 25y = 22. Since the right-hand side is a constant, we can assume a constant solution y_p = a.

Substituting y_p = a into the differential equation, we find that 25a = 22, which gives a = 22/25.

Maximum area enclosed by Mona for the fencing is 640,000 square yards. And the dimensions( length and width ) of the rectangle to enclosed maximum area are 800 yard each.

As given in the question,

Perimeter of the rectangular area encloses for fencing = 3200 yards

Let 'x' and 'y' be the length and width of the rectangle.

2( x + y ) = 3200

⇒ x + y = 3200/2

⇒y = 1600 - x

Area of rectangular field 'A' = xy

⇒ A = x ( 1600 - x )

⇒ A = 1600x - x²

Differentiate both the side of the equation we get,

dA/dx = 1600 - 2x

For Maximum Area dA/dx = 0

1600 -2x =0

⇒ 2x = 1600

⇒ x= 800 yards

Now, y = 1600 - 800

          = 800 yards

Maximum area = (800) (800)

                        = 640,000 square yards

Therefore, the dimensions of the rectangular area are 800yards each and its maximum area is equal to 640,000 square yards.

Answer:

confidence interval = ( -0.38 , 0.08 )

Step-by-step explanation:

Given data :

n1 = 55 , n2 = 60 ,

Let P1 ( proportion of SUV sales at store A ) = 30 / 55 = 0.55

P2 ( sample proportion of SUV sales at store B ) = 42/60 = 0.70

The Z-value at 99% confidence Interval = 2.58

Determine the 99% confidence interval for difference in proportion

applying the formula below

( P1 - P2 ) ± Z ( \(\sqrt{p1( 1-p1)/n1 + p2(1-p2)/n2}\)

Input values above into equation

confidence interval = ( -0.38 , 0.08 )

Your average waiting time will be approximately 1 minute.

As the first passenger, you will not have to wait for any other passengers to get in the taxi. However, the taxi will wait for 2 passengers to arrive or 3 minutes to pass since your boarding.

Since passengers arrive according to a Poisson process with an average of 60 passengers per hour, the arrival rate lambda can be calculated as:

lambda = average number of passengers per time unit = 60/60 = 1 passenger per minute

The time between two consecutive passenger arrivals follows an exponential distribution with parameter lambda. Thus, the probability of waiting less than t minutes for the second passenger to arrive can be calculated as:

P(wait < t) = 1 - e^(-lambda*t)

We need to find the average waiting time until the second passenger arrives. This can be calculated as the area under the probability distribution curve divided by the arrival rate lambda:

average waiting time = integral from 0 to infinity of t*(1 - e^(-lambda*t)) dt / lambda

Using integration by parts, we can solve this integral to get:

average waiting time = 1/lambda + (1 - e^(-lambda*t))/(lambda^2)

Plugging in the values, we get:

average waiting time = 1/1 + (1 - e^(-1*3))/(1^2) = 1 + (1 - 0.0498) = 1.9502 minutes

Therefore, as the first passenger, your average waiting time until the second passenger arrives is 1.9502 minutes.

To answer your question, let's consider the two possible scenarios:

1. Two passengers are collected: In this case, the first passenger (you) waits for the second passenger to arrive. Since the arrival rate is 60 passengers per hour, the average time between arrivals is 1 minute (60 minutes / 60 passengers).

2. Three minutes have expired: In this case, the taxi departs after 3 minutes even if only one passenger (you) is in the taxi.

On average, the waiting time for the first passenger (you) will be the minimum of these two scenarios. Thus, your average waiting time will be approximately 1 minute.

Biking at 10 mph it takes kristen 1/4 an hour the train station to go to work.kristen then takes the train to work and it takes another 1/4 hour to get to work when the train travels 28 mph. how far does kristen travels to work Kristen travels a total of 9.5 miles to work.


1. First, we need to find the distance Kristen travels by bike. We can do this using the formula distance = speed × time. In this case, Kristen's speed is 10 mph and she bikes for 1/4 hour. So, the distance she travels by bike is:

Distance = 10 mph × 1/4 hour = 2.5 miles

2. Next, we need to find the distance Kristen travels on the train. Again, we use the formula distance = speed × time. The train's speed is 28 mph and it takes 1/4 hour to get to work. So, the distance traveled on the train is:

Distance = 28 mph × 1/4 hour = 7 miles

3. Now, we add the distances from both parts of the journey to find the total distance traveled:

Total distance = distance by bike + distance by train = 2.5 miles + 7 miles = 9.5 miles

Answer:

(4, - 6 )

Step-by-step explanation:

7x - y = 34 ( multiply through by - 1 )

- 7x + y = - 34 ( add 7x to both sides )

y = 7x - 34 → (1)

2x + 3y = - 10 → (2)

substitute y = 7x - 34 into (2)

2x + 3(7x - 34) = - 10

2x + 21x - 102 = - 10

23x - 102 = - 10 ( add 102 to both sides )

23x = 62 ( divide both sides by 23 )

x = 4

substitute x = 4 into (1)

y = 7(4) - 34 = 28 - 34 = - 6

solution is (4, - 6 )

To solve the given system of equations using Gauss-Jordan elimination, we first need to simplify the given equations and put them into a matrix form.

Here are the following steps:
Equation 1: 6d + 12e - 185 = -138 - 2d + e + 315 - 171
Simplify:
8d + 11e = 191

Equation 2: 40 + de - 285 = -168
Simplify:
de - 245 = -168
de = 77

Now, let's create an augmented matrix for the system of equations:
```
|  8   11  |  191  |
|  0    1  |   77  |
```

Since we can't perform Gauss-Jordan elimination on a system with a product of variables (de), we'll have to solve for one variable and substitute it into the other equation.

From the second row of the matrix, we have:
e = 77

Now substitute e into the first equation:
8d + 11(77) = 191
8d + 847 = 191
8d = -656
d = -82

Now we have the ordered pair (d, e) = (-82, 77).

Since there are only two variables in the system, there's no need for an ordered triple. The solution is (-82, 77).

The best statement that describes the function of the logic variable X is: A. X is a variable whose value is 1 or 0.

Logic variables typically represent binary states or conditions, where 1 represents "true" or "on" and 0 represents "false" or "off". Therefore, option A accurately describes the function of the logic variable X as having a value of either 1 or 0. Logic variables are often used in the field of logic and computer science to represent binary states or conditions. The value of a logic variable can only be one of two possibilities: 1 or 0.

In this context, 1 typically represents "true" or "on," indicating that a certain condition is satisfied or a certain state is active. On the other hand, 0 represents "false" or "off," indicating that the condition is not satisfied or the state is inactive.

By using logic variables, we can model and manipulate binary logic in a precise and systematic manner. The values of logic variables are fundamental in logical operations, such as AND, OR, and NOT, which are essential in designing and analyzing digital circuits, programming, and logical reasoning.

There are 1287 different ways Ms. Bell can create a 5-Member committee of seniors from her class.

Ms. Bell's mathematics class consists of 6 sophomores, 11 juniors, and 13 seniors. The task is to determine the number of different ways Ms. Bell can create a 5-member committee of seniors, with each senior having an equal chance of being selected.

To solve this problem, we can use combinations. The number of ways to select a committee of 5 seniors from a group of 13 can be calculated using the combination formula:

C(n, k) = n! / (k!(n - k)!)

Where n represents the total number of elements (seniors in this case), and k represents the number of elements to be selected (5 in this case). The exclamation mark denotes the factorial of a number.

Using the combination formula, the number of ways to select a 5-member committee from 13 seniors is:

C(13, 5) = 13! / (5!(13 - 5)!) = 13! / (5! * 8!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
