x²y' - 2xy' + (x² + 2)y = 0 is the associated homogeneous equation with non-homogeneous ODE x²yⁿ - 2xy' + (x² +2)y = 3x³.

It should be noted that the equation is same as the variable coefficient linear second order non-homogeneous ODE but just the right side zero.

The complementary solutions or homogeneous solutions to this homogeneous equation serve as the foundation for the space of all solutions to the non-homogeneous equation.

By assuming that y has the form y(x) = xr and substituting this into the homogeneous equation to create a characteristic equation, we can determine the complementary solutions. We may find the values of r that correspond to solutions of the type y(x) = xr by looking at the characteristic equation's roots.

The sum of the measures of the interior angles is 1260 degrees

From the question, we have the following parameters that can be used in our computation:

An interior angle = 140 degrees

The sum of interior angles of a regular polygon is:

S = (n - 2) × 180

Where n is the number of sides of a polygon

Also, we have

S = 140n

Substitute the known values in the above equation, so, we have the following representation

140n = (n - 2) × 180

Expand

140n = 180n - 360

This gives

40n = 360

Divide

n = 9

Recall that

S = (n - 2) × 180

So, we have

S = (9 - 2) × 180

Evaluate

S = 1260

Hence, the sum of the measures of the interior angles is 1260 degrees

Therefore, the perimeter of the rectangle is 38 units that is option C.

A coordinate is a set of numbers or values that specifies the position or location of a point or object in a space. In mathematics, coordinates are used to describe the position of a point in a plane, a space or a higher-dimensional object. Coordinates can be represented by ordered pairs or tuples, where the first value corresponds to the position on the horizontal axis, and the second value corresponds to the position on the vertical axis.

Here,

First, we need to find the distance between points A and B to determine the length of the rectangle:

Distance AB = |yB - yA|

= |8 - 2|

= 6

Next, we need to find the distance between points B and C to determine the width of the rectangle:

Distance BC = |xC - xB|

= |6 - (-7)|

= 13

Since opposite sides of a rectangle are equal in length, we know that the distance between points A and D is also 13, and the distance between points C and D is also 6.

Therefore, the perimeter of the rectangle is:

Perimeter = 2 * (length + width)

Perimeter = 2 * (13 + 6)

Perimeter = 2 * 19

Perimeter = 38

So the answer is (C) 38.

(d) Probability of at least one major earthquake in the next 49 years is 0.9884, and (e) the probability of no major earthquakes in the next 49 years is 0.0116.

We will use the Poisson distribution to compute the probabilities. First, we need to find the value of λ (average number of earthquakes in a given time period).

(d) Compute the probability of at least one major earthquake in the next 49 years:

1. Calculate λ for 49 years:

(2.0 earthquakes / 22 years) * 49 years = 4.45 (rounded to the nearest hundredth)

2. Compute the probability of no major earthquakes (P(0)) in the next 49 years using Poisson distribution formula:

P(0) = (e^(-λ) * (λ^0)) / 0! = (e^(-4.45) * (4.45^0)) / 1 = 0.0116 (rounded to 4 decimal places)

3. Compute the probability of at least one major earthquake:

P(at least 1) = 1 - P(0) = 1 - 0.0116 = 0.9884

So, the probability of at least one major earthquake in the next 49 years is 0.9884 (rounded to 4 decimal places).

Answer:

y = 1 + 2√7 or y = 1 - 2√7

Step-by-step explanation:

To complete the square, you need to add and subtract the square of half of the coefficient of the y term.

First, you can factor out a 1 from the y^2 - 2y term:

y^2 - 2y - 27 = 0

y^2 - 2y = 27

Next, take half of the coefficient of the y term (-2/2 = -1) and square it (1):

y^2 - 2y + 1 - 1 = 27

The "+1 -1" doesn't change the value of the equation, it's just a way to add 0 to the equation so we can complete the square.

Now you can rewrite the left side as a perfect square:

(y - 1)^2 - 28 = 0

Add 28 to both sides:

(y - 1)^2 = 28

Take the square root of both sides (remembering to include both positive and negative square roots):

y - 1 = ±√28

y = 1 ± 2√7

So the solutions are:

y = 1 + 2√7

y = 1 - 2√7

Answer: y=± 2√7+1

Step-by-step explanation: Use the formula

(b/2)^2  in order to create a new term. Solve for y by using this term to complete the square.

Answer:Each of the shaded sections represents 25% of the total number of students in the class, and since we have evenly distributed the 12 students among them, each shaded section now represents 30% of the students (i.e., 25% + 5% = 30%).

Step-by-step explanation: To model this situation, we need to determine the total number of students in the class. We can use the given percentage to set up a proportion:

40% = 12 students / x total students

To solve for x, we can cross-multiply and simplify:

0.4x = 12

x = 12 / 0.4

x = 30

Therefore, there are 30 students in the class.

To evenly distribute the 12 students in the 4 shaded sections, we can divide 12 by 4 to get the number of students for each section:

12 students / 4 sections = 3 students per section

Let's use the method of setting up a system of equations to solve this problem.

Let x be the number of pints of the first type of fruit drink (30% pure), and y be the number of pints of the second type of fruit drink (55% pure). We want to find the values of x and y that will produce 60 pints of a mixture that is 40% pure.

We can start by setting up two equations based on the information given:

Equation 1: x + y = 60 (since we want to produce 60 pints of the mixture)

Equation 2: 0.3x + 0.55y = 0.4(60) (since we want the mixture to be 40% pure)

Simplifying Equation 2, we get:

0.3x + 0.55y = 24

Now we have a system of two equations with two unknowns:

x + y = 60

0.3x + 0.55y = 24

We can solve this system using substitution or elimination. Here, we'll use substitution:

Solving Equation 1 for x, we get x = 60 - y. Substituting this expression for x in Equation 2, we get:

0.3(60 - y) + 0.55y = 24

Expanding and simplifying, we get:

18 - 0.3y + 0.55y = 24

Combining like terms, we get:

0.25y = 6

Dividing by 0.25, we get:

y = 24

Substituting this value of y back into x + y = 60, we get:

x + 24 = 60

Solving for x, we get:

x = 36

Therefore, we need 36 pints of the 30% pure fruit drink and 24 pints of the 55% pure fruit drink to make 60 pints of a mixture that is 40% pure.

The theoretical probability of rolling a one or two is 3/5 or 0.6 as a decimal.

The theoretical probability of an event happening is the number of favorable outcomes divided by the total number of possible outcomes.

In this case, Alexandria rolled the number cube 60 times and recorded her results in the table.

Looking at the table, we can see that the number 1 came up 16 times and the number 2 came up 20 times.

So the number of favorable outcomes is 16 + 20 = 36.

And the total number of possible outcomes is 60.

Therefore, the theoretical probability of rolling a one or two is:

P(1 or 2) = favorable outcomes/total outcomes = 36/60

Simplifying the fraction, we get:

P(1 or 2) = 3/5

So the theoretical probability of rolling a one or two is 3/5 or 0.6 as a decimal.
