How to solve the given differential equation?To solve the given differential equation y' = xy using the power series substitution y = ∑ Cₙxⁿ, we will first find the derivative of y, then substitute both y and y' into the given equation, and finally determine the coefficients.
Step 1: Find the derivative of y.
y = ∑ Cₙxⁿ
y' = ∑ nCₙxⁿ⁻¹
Step 2: Substitute y and y' into the given equation.
∑ nCₙxⁿ⁻¹ = x ∑ Cₙxⁿ
Step 3: Match the coefficients on both sides of the equation.
For n = 1, C₁ = C₀.
For n = 2, 2C₂ = C₁ => C₂ = C₀/2.
For n = 3, 3C₃ = C₂ => C₃ = C₀/6.
For n = 4, 4C₄ = C₃ => C₄ = C₀/24.
For n = 5, 5C₅ = C₄ => C₅ = C₀/120.
For n = 6, 6C₆ = C₅ => C₆ = C₀/720.
So, the coefficients are:

What two nonnegative real numbers with a sum of 64 have the largest possible product?
The two non negative real numbers with a sum of 64 that have the largest possible product are; 32 and 32.
How do we solve the nonnegative real numbers?Let the two numbers be x and y.
Thus, if their sum is 64, then we have;
x + y = 64
y = 64 - x
Their product will be;
P = xy
Putting (64 - x) for y in the product equation we have;
P = (64 - x)x
P = 64x - x²
Since the product is maximum, let us find the derivative;
P'(x) = 64 - 2x
At P'(x) = 0, we have;
64 - 2x = 0
2x = 64
x = 64/2
x = 32
Thus; y = 64 - 32
y = 32

How many possible values can be assigned to type "logic"?
a.4
b.5
c.2
d.6
e.3
The number of possible values that can be assigned to the type "logic" is 2, and the correct answer is option c.2.
In logic, the type "logic" refers to a variable or proposition that can take on one of two possible values: true or false.
These values are commonly denoted as 1 (true) and 0 (false), or alternatively as "T" and "F".
Since the type "logic" can only have two possible values, the correct answer is option c.2.
There are no other valid values for this type.
It is important to note that in some programming languages or systems, additional representations or extensions of logic may exist.
For example, some languages may include a "null" or "undefined" value in addition to true and false.
However, in the context of a basic logic type, the number of possible values remains restricted to two: true and false.

which of the following scenarios are binomial? a quality control inspector takes a random sample of 20 items from a large lot, inspects each item, classifies it as poor, satisfactory, or good, and counts the number of each type of item in the sample. an engineer chooses a srs of 10 switches from a shipment of 10,000 switches. suppose 10% of the switches in the shipment are bad. the engineer counts the number x of bad switches in the sample. you observe the sex of the next 20 children born at a local hospital: x is the number of girls among them. a couple decided to continue having children until their first girl is born: x is the total number of children the couple has.
Only scenario 2 is Binomial here.
What exactly are binomials?
A binomial polynomial is a polynomial with just 2 terms. For example, x + 2 is a binomial, where x and 2 are two independent terms. Furthermore, the coefficient of x is one, the exponent of x is one, and the constant is two. As a result, a binomial is a two-term algebraic statement with variables, coefficients, exponents, and a constant.
x² + 4x is another example of a binomial polynomial. As a result of this binomial, we may assert the following:
The two words are x² and 4x.
x = variable
x² has an exponent of 2 and x is 1.
The coefficient of x² is one, whereas the coefficient of x is four.
Now,
As there are four requirements that must be satisfied for an experiment to be binomial and those are
1. Two outcomes that are mutually exclusive (success or failure)2. A set number of trials3. The success rate for each trial must be the same.4. Each trial is distinct.and only scenario 2 satisfies these conditions.

3x+4y=17
-4x-3y=-18
Answer: (3,2)
Step-by-step explanation:
For this set of system of equations, let's use elimination method to find x and y. Let's eliminate y first. In order to do so, the y values have to be the same. Therefore, you multiply the top equation by 3 and the bottom equation by 4.
9x+12y=51
-16x-12y=-72
Now, we can add the 2 equations together for the y to cancel out.
-7x=-21

Show that the equation of the line in R2 through distinct points (x, yi) and (x2. y2) can be written as x2 y2」 8. Find a 3 × 3 determinant equation similar to that in Exercise 7 that describes the equation of the line through (x1, yi) with slope m. Exercises 9 and 10 concern determinants of the following Vander- monde matrices.
The equation of the line in R² through distinct points (x₁, y₁) and (x₂, y₂) x(y₂ - y₁) - y(x₂ - x₁) = 0. The 3 × 3 determinant equation similar to Exercise 7 that describes the equation of the line through (x₁, y₁) with slope m is m -1 y₁ - mx₁ = 0 x y 1 ,x₂ y₂ 1 .
The equation of the line in R² through distinct points (x₁, y₁) and (x₂, y₂) x(y₂ - y₁) - y(x₂ - x₁) = 0, the point-slope form of the equation of a line.
The point-slope form of the equation of a line passing through a point (x₁, y₁) with slope m is given by
y - y₁ = m(x - x₁)
Substituting the given points (x₁, y₁) and (x₂, y₂),
For the point (x₁, y₁)
y - y₁ = m(x - x₁) (1)
For the point (x₂ y₂)
y - y₂ = m(x - x₂) (2)
To eliminate y, equation (2) from equation (1)
(y - y₁) - (y - y₂) = m(x - x₁) - m(x - x₂)
y - y₁ - y + y₂ = m(x - x₁) - m(x - x₂)
y - y + y₂ - y₁ = m(x - x + x₂ - x₁)
y₂ - y₁ = m(x₂ - x₁)
Rearranging the equation,
x(y₂ - y₁) - y(x₂ - x₁) = 0
For Exercise 8, to find a 3 × 3 determinant equation similar to that in Exercise 7 that describes the equation of the line through (x₁, y₁) with slope m, the point-slope form as before.
The equation of the line passing through (x₁, y₁) with slope m
y - y₁ = m(x - x₁)
Expanding the equation,
y - y₁ = mx - mx₁
Rearranging terms,

need help for number 3
Answer:
Remember that a line segment is the portion of a straight line that directly connects two given points. Unlike a line, it does not extend off to infinity in both directions. To find the length, we just use the distance formula between the two points provided.
Example:
Find the distance between (-2,8) and (-7,-5). Said another way, find the length of the line segment between points (-2,8) and (-7,-5).
First, find the distance between the x-coordinates. To do this, subtract one number from the other and then take its absolute value.
We have: |-2-(-7)| = |5| = 5.
Then repeat with the y-coordinates.
We have: |8-(-5)| = |13| = 13.
NOTE: It does NOT matter which way you subtract the numbers because the absolute value of the answer would be the same anyway.
Finally, to compete the length (or distance), square BOTH values, add them, and take the square root. Here's the first part:
\(5^{2}\) + \(13^{2}\) = 25 + 169 = 194
Taking the square root of 194 and rounding to TWO decimal places, we get a distance of 13.93:
\(\sqrt(194)\) = 13.93
By the way, what you are actually doing is using the Pythagorean Theorem on an imaginary right triangle with the line joining the two lines being the hypotenuse.
The general formula for distance between two points is the following: \(\sqrt{x^2+y^{2}\) , where x and y are the change in x and y between the two points.

a) tn = 5 + 14
b) tn= 5n² + 14
c) tn= 5n(n+14)
d) tn= 5n + 14
The correct formula that defines an arithmetic sequence is option d) tn = 5n + 14.
An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms remains constant. In other words, each term can be obtained by adding a fixed value (the common difference) to the previous term.
In option a) tn = 5 + 14, the term does not depend on the value of n and does not exhibit a constant difference between terms. Therefore, it does not represent an arithmetic sequence.
Option b) tn = 5n² + 14 represents a quadratic sequence, where the difference between consecutive terms increases with each term. It does not represent an arithmetic sequence.
Option c) tn = 5n(n+14) represents a sequence with a varying difference, as it depends on the value of n. It does not represent an arithmetic sequence.
Option d) tn = 5n + 14 represents an arithmetic sequence, where each term is obtained by adding a constant value of 5 to the previous term. The common difference between consecutive terms is 5, making it the correct formula for an arithmetic sequence.
