To determine which differential equation(s) are linear, we need to examine the form of each equation. A linear differential equation is one that can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x), b(x), c(x), and g(x) are functions of x.

The differential equation 2xy" - 5xy' + y = sin(3x) is linear. It can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x) = 2x, b(x) = -5x, c(x) = 1, and g(x) = sin(3x).
The differential equation (v)² + xy = In(x) is not linear. It does not follow the form a(x)y" + b(x)y' + c(x)y = g(x) because it contains a term with (v)², where v represents the derivative of y with respect to x. This term does not have a linear coefficient.
The differential equation y' + sin(y) = e^(3x) is linear. It can be written in the form a(x)y' + b(x)y = g(x), where a(x) = 1, b(x) = sin(y), and g(x) = e^(3x).
The differential equation (x²+1)y" - 3y - 2x³y = -x - 9 is not linear. It does not follow the form a(x)y" + b(x)y' + c(x)y = g(x) because it contains a term with (x²+1)y", where the coefficient is a function of x.
The differential equation y' + xy = y" is linear. It can be written in the form a(x)y' + b(x)y = g(x), where a(x) = 1, b(x) = x, and g(x) = y".

Answer:

2. is the second one, 3. is the 3rd one (i think)

Step-by-step explanation:

Step-by-step explanation:

the arc angle KLI = 142°.

that means that the arc angle KJI = 360 - 142 = 218°.

this is twice the inscribed opposite angle on the arc (L).

so,

(a)

angle KLI = 218/2 = 109°

(b)

for the same reason

angle LKJ is half of the arc angle LIJ.

arc angle LIJ = 2× angle LKJ = 2×66 = 132°

that means

arc angle LKJ = 360 - 132 = 228°

angle LIJ = half of arc angle LKH = 228/2 = 114°

FYI for such an inscribed quadrilateral there is Akari the rule that the sum of opposite angles have to be 180°.

so, angle LIJ is opposite of angle LKJ.

angle LIJ = 180 - angle LKJ = 180 - 66 = 114°

Answer:

  x = 5

Step-by-step explanation:

You want the equation of a line with undefined slope and an x-intercept of 5.

Slope is the ratio of "rise" to "run" for a line. If the line is vertical, the "run" is zero, making the denominator of the ratio is zero. Division by zero gives an "undefined" result.

If the slope of a line is "undefined", it is a vertical line. It has the same x-value everywhere. Its equation is ...

  x = c . . . . . for some constant

Here, the vertical line crosses the x-axis at x=5. That is the equation of the line:

  x = 5

Answer:

43°

Step-by-step explanation:

Complementary angles add up to 90° in measurement.

One angle is 47 degrees.

\(90-47=\boxed{43}\)

The measurement of the other angle would be 43°.

Hope this helps.

The measure of other angle is 43 degree.

Complementary angles are those whose combined angle is 90 degrees or less. To put it another way, two angles are said to be complimentary if they combine to make a right angle. In this case, we say that the two angles work well together.

Given that.

Two angles are complementary.

Now consider one angle = x degree

And other angle  = y degree

Then according to question,

Measure of angle x = 47 degree

We know that,

The sum of complementary angles are equal to 90 degree.

Therefore,

x + y = 90

x + 47 = 90

       x = 90 - 47

       x  = 43

Hence, the other angle is = 43 degree.

The identity \(A^2 - B^2 = (A + B) (A - B)\) is true for all values of A and B. Compute the whole number value of \(2021^2 -2022^2\)

Answer:

\(2021^2 - 2022^2 = -4043\)

Step-by-step explanation:

Given

\(A^2 - B^2 = (A + B) (A - B)\)

Required

Solve:  \(2021^2 -2022^2\)

In: \(2021^2 -2022^2\)

\(A = 2021; B = 2022\)

Answer: 0.8 miles

Step-by-step explanation:

Let the distance in miles for 2.5 minutes be A

10 minutes -> 3.2 miles

2.5 minutes -> A miles

Using proportion,

2.5 / 10 = A / 3.2

1 / 4 = A / 3.2

Hence,
A = 3.2 / 4 = 0.8

The metric system of measurement is based on the number 10.

This system is also known as the International System of Units (SI) and is used in most countries around the world. In the metric system, various units of measurement are defined as multiples or fractions of a base unit, which is defined for each quantity being measured. For example, the base unit for length is the meter, and the base unit for mass is the kilogram. Prefixes such as kilo-, centi-, and milli- are used to indicate multiples or fractions of the base unit, based on factors of 10. For example, a kilometer is 1000 meters, a centimeter is 1/100 of a meter, and a milligram is 1/1000 of a gram. This makes the metric system easy to use and convert between units, as well as consistent and universally recognized.

The environment changed in such a way that, "guppies with small spots had a better chance of survival and reproduction, leading to an increase in their population and a decrease in the population of guppies with large spots".

Over many generations, guppies with small spots had a survival advantage in the river because the rocks on the river bottom became smaller. This made guppies with small spots harder for larger fish to see and catch, increasing their chances of survival and reproduction.

As a result, more guppies with the small spot gene passed it on to their offspring, leading to an increase in the population of guppies with small spots. At the same time, the population of guppies with large spots decreased as they were more visible to predators and had a lower chance of survival. This process of natural selection led to a change in the frequency of different traits within the population of guppies.

The derivative dy/dx is equal to -2 / (5x) in terms of x and y.

We are asked to find the derivative dy/dx of the implicitly defined function x² × \(y^5\) × \(e^y\) = 0. To find this, we'll use implicit differentiation.
Implicit differentiation means we differentiate both sides of the equation with respect to x, treating y as a function of x, and then solve for dy/dx. So, let's differentiate both sides:
d/dx (x² × \(y^5\) × \(e^y\)) = d/dx (0)
First, we'll differentiate the left side using the product rule and chain rule:
(2x × y^5 × e^y) + (x² × 5y^4 × e^y × dy/dx) = 0
Now, we'll isolate dy/dx by subtracting the first term from both sides and then dividing by the second term:
dy/dx = - (2x × \(y^5\) × \(e^y\)) / (x² × \(5y^4\) ×\(e^y\))
We can simplify this expression by canceling out some common factors:
dy/dx = - (2x) / (5x²)
Further simplification gives:
dy/dx = -2 / (5x)
Thus, the derivative dy/dx is equal to -2 / (5x) in terms of x and y.

We have the inequality:

-4 < (3x - 2)/5 ≤ 6

We multiply all the sides by 5:

-4*5 < 5*(3x - 2)/5 ≤ 6*5

-20 < 3x - 2 ≤ 30

Now, we add 2 to all the sides of the inequality:

-20 + 2 < 3x - 2 + 2 ≤ 30 + 2

-18 < 3x ≤ 32

Finally, we divide by 3:

-18/3 < 3x/3 ≤ 32/3

-6 < x < 32/3

It can be partial differential equations, one for the function of x (X(x)) and another for the function of t (T(t)).  suggests that the product of the second derivative of X(x) with respect to x and  function T(t) is equal to a constant multiplied by the function U(x, t).

The given partial differential equation is t^2 * uU_xx + x * u * at * tu = 0, where u represents the function u(x, t), and subscripts denote partial derivatives with respect to the respective variables. To solve this equation, we can separate the variables by assuming u(x, t) = X(x) * T(t), where X(x) represents the function solely dependent on x, and T(t) represents the function solely dependent on t.Substituting this assumption into the original equation, we obtain t^2 * (X''(x) * T(t)) + x * (X(x) * T'(t) + X'(x) * T(t)) = 0. Now, we can divide the equation by t^2 * X(x) * T(t), resulting in (X''(x) / X(x)) + (x * T'(t) + X'(x) * T(t)) / (t * T(t)) = 0.
Since the left-hand side depends only on x, and the right-hand side depends only on t, they must be equal to a constant, denoted by A. Therefore, we have X''(x) / X(x) = -A and (x * T'(t) + X'(x) * T(t)) / (t * T(t)) = A.These equations can be further simplified and solved independently to find the functions X(x) and T(t), thus determining the solution u(x, t) = X(x) * T(t) of the given partial differential equation.
