CD = 13

Step-by-step explanation:

BE = CD in a parallelogram

1+4x = 5x -2

Subtract 4x from each side

1+4x-4x = 5x-2 -4x

1 = x-2

Add 2 to each side

1+2 = x-2+2

3 =x

The length of CD

CD = 5x-2 = 5*3 -2 = 15-2 = 13

Step-by-step explanation:

W= (-8,1) → (x₁,y₁)

Y= (4,-4) → (x₂,y₂)

Distance of WY= \(\sqrt{(x1-x2)^{2}+(y1-y2)^{2} }\)

The distributed computation (e, →) is said to be consistent if all computations lead to the same result, regardless of the order in which the steps are performed.

Let g and h be consistent cuts of a distributed computation (e, →).

We must demonstrate that g ∪ h and g ∩ h are also consistent cuts of (e, →).

Let R be the set of events that are in both g and h. If we remove R from either g or h, we get a consistent cut since the removed events cannot cause a change in the outcome.

By removing R from both g and h, we obtain two new consistent cuts: g − R and h − R.

Thus, we can write:g = (g − R) ∪ R and h = (h − R) ∪ R. Since (g − R) and (h − R) are consistent cuts, it follows that their union, g ∪ h, is also a consistent cut. I

f we let S be the set of events that are in both g and h, then we can write:g = (g ∩ h) ∪ (g − S) and h = (g ∩ h) ∪ (h − S).

Again, (g − S) and (h − S) are consistent cuts, so their intersection, g ∩ h, is also a consistent cut.

Therefore, if g and h are consistent cuts of a distributed computation (e, →), then so are g ∪ h and g ∩ h.

Total hair cut off  = \(\frac{7}{8}\)

Step-by-step explanation:

Given - Ameen went to the salon and had \(\frac{3}{8}\) of an inch of hair cut off. The next day she went back and asked for another \(\frac{1}{2}\) of an inch to be cut off.

To find - How much hair did she have cut off in all?

Proof -

Given that,

Firstly,

She cut off her hair = \(\frac{3}{8}\)

Then,

She cut off her hair = \(\frac{1}{2}\)

So,

Total hair cut off = \(\frac{3}{8}\) + \(\frac{1}{2}\)

                           = \(\frac{3 + 4}{8}\) = \(\frac{7}{8}\)

⇒Total hair cut off  = \(\frac{7}{8}\)

The quadratic function in the standard form containing the point (-7, 5) and vertex (1, 9) is y = (-1/16)(x - 1)² + 9.

The vertex form of a quadratic function with vertex (h, k) is written as

y = a(x - h)² + k, where (x, y) denotes a point on the parabola. Real integers a, h, and k are also included.

Given:

Point (x, y) = (-7, 5)  

Vertex (h,k) = (1, 9)

The general equation of quadratic function in vertex form is:

 y = a(x - h)² + k

To solve for a, substitute the given point (x,y) = (-7,5) into the equation.

5 = a(-7 - 1)² + 9

a(-8)² = -4

a = -4 /64

a = -1/16

Therefore, the required quadratic function is,

The total number of games of checkers played altogether is 12.

.Given that Alex, Brad, Calvin, and Dennis are playing checkers and each of the 4 boys played 2 games with every other player.

To find the total number of games of checkers played by them, we can use the concept of combinations as follows:There are 4 players and each of them has to play 2 games with every other player.

So, the total number of games that each player plays is given by C(3, 2) which is equal to 3. (Because we need to select any 2 out of 3 players)

The total number of games of checkers played can be found by adding the number of games played by each player.

So,Total number of games played = 4 × 3= 12

Hence, the total number of games of checkers played altogether is 12.

The solution to the given differential equation is \(y = a_0x^{[0]} + a_1x^{[1]} + a_2x^{[2]}\), where a_0, a_1, and a_2 are constants.

To fathom the given differential equation, xy'' + y' = 0, we will begin by expecting a control arrangement of the frame y = ∑(n=0 to ∞) a_nx^n, where a_n speaks to the coefficients to be decided.

Separating y with regard to x, we get:

\(y' = ∑(n=0 to ∞) a_n(nx^[(n-1))] = ∑(n=0 to ∞) na_nx^[(n-1)]\)

Separating y' with regard to x, we get:

\(y'' = ∑(n=0 to ∞) n(n-1)a_nx^[(n-2)]\)

Presently, we substitute these expressions for y and its subsidiaries into the differential condition:

\(x(∑(n=0 to ∞) n(n-1)a_nx^[(n-2))] + (∑(n=0 to ∞) na_nx^[(n-1))] =\)

After improving terms, we have:

\(∑(n=0 to ∞) n(n-1)a_nx^[(n-1)] + ∑(n=0 to ∞) na_nx^[n] =\)

Another, we compare the coefficients of like powers of x to zero, coming about in a boundless arrangement of conditions:

For n = 0: + a_0 = (condition 1)

For n = 1: + a_1 = (condition 2)

For n ≥ 2: n(n-1)a_n + na_n = (condition 3)

Disentangling condition 3, we have:

\(n^[2a]_n - n(a_n) =\)

n(n-1)a_n - na_n =

n(n-1 - 1)a_n =

(n(n-2)a_n) =

From equation 1, a_0 = 0, and from equation 2, a_1 = 0.

For n ≥ 2, we have two conceivable outcomes:

n(n-2) = 0, which gives n = or n = 2.

a_n = (minor arrangement)

So, the solution to the given differential equation is \(y = a_0x^{[0]} + a_1x^{[1]} + a_2x^{[2]}\), where a_0, a_1, and a_2 are constants.

The process of finding the derivative of a function is called differentiation.

Differentiation is a fundamental concept in calculus that involves determining the rate at which a function changes with respect to its independent variable. It allows us to analyze the behavior of functions, such as finding slopes of curves, identifying critical points, and understanding the shape of graphs.

The derivative of a function represents the instantaneous rate of change of the function at any given point. It provides information about the slope of the tangent line to the graph of the function at a specific point.

The notation used to represent the derivative of a function f(x) with respect to x is f'(x) or dy/dx. The derivative can be interpreted as the limit of the difference quotient as the interval approaches zero, representing the infinitesimal change in the function.

By applying differentiation techniques, such as the power rule, product rule, chain rule, and others, we can find the derivative of a wide range of functions. Differentiation is a powerful tool used in various areas of mathematics, physics, engineering, economics, and other fields to analyze and solve problems involving rates of change.

The answers correct because, If the range and median is 13 that means that the highest and lowest point equal 13 and the middle/the line in the graphs should be on 13. A doesn't have the line/median on 13 so it is not that answer. But B and C have the line/median on the line so we just have to check the range. The range of B is: 9, The range of C is: 13.

The formula for the area of a circle is:

A = πr^2

We are given that the radius of Jayden's circular garden is 15 yards. Therefore, we can plug this value into the formula to find the area:

A = π(15)^2

A = 225π

To round the answer to the nearest whole number, we need to approximate the value of π. Using 3.14 as an approximation for π, we can calculate the approximate area:

A ≈ 225(3.14)

A ≈ 706.5

Rounding to the nearest whole number, we get:

Jayden will need to cover a total area of about 707 square yards.

To compute the median of three sets of scores, we need to arrange the scores in order from smallest to largest and then select the middle score.

Mean, median and mode are measures of central tendency and are used to describe the central value of a set of data. The mean is the average of all the values in the set, the median is the middle value and the mode is the most frequently occurring value.

To compute the mean of three sets of scores, we need to sum up all the scores and divide by the total number of scores. This can be represented by the formula:

Mean = (Score1 + Score2 + Score3) / 3

To compute the median of three sets of scores, we need to arrange the scores in order from smallest to largest and then select the middle score. This can be represented by the formula:

Median = (Score2 + Score3) / 2

To compute the mode of three sets of scores, we need to identify the score that occurs the most frequently. This can be represented by the formula:

Mode = Most Frequently Occurring Score

For example, if the three scores are 3, 7, and 4, then the mean is (3 + 7 + 4) / 3 = 4.67, the median is (3 + 4) / 2 = 3.
