To use the splitpts function in Matlab, you will first need to define two sets of points with different arrays for each set. Then, you can use the syntax newSetOfPoints = splitpts(originalSetOfPoints) to split the original set of points into two new sets.

The "splitpts" function in MATLAB is used to split a set of points into two sets based on a specified split point. Here are the steps to use this function:

1. Define the set of points you want to split. For example:
```
points = [1 2 3 4 5 6 7 8 9 10];
```

2. Specify the split point. This can be any number between the minimum and maximum values of the set of points. For example:
```
splitPoint = 5;
```

3. Use the "splitpts" function to split the set of points into two sets. The first set will contain all the points less than or equal to the split point, and the second set will contain all the points greater than the split point. For example:
```
[set1, set2] = splitpts(points, splitPoint);
```

4. The resulting sets will be stored in the variables "set1" and "set2". You can display these sets using the "disp" function:
```
disp(set1);
disp(set2);
```

The output will be:
```
1 2 3 4 5
6 7 8 9 10

We have proved that Angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.

To prove that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, we can use the following steps:

Step 1: Join points A and C with a line segment. Let's label the point where AC intersects with line segment BD as point E.

Step 2: Since line segment AC is drawn, we can consider triangle ABC and triangle ADC separately.

Step 3: In triangle ABC, we have angle B + angle ABC + angle BCA = 180 degrees (due to the sum of angles in a triangle).

Step 4: In triangle ADC, we have angle D + angle ADC + angle CDA = 180 degrees.

Step 5: From steps 3 and 4, we can deduce that angle B + angle ABC + angle BCA + angle D + angle ADC + angle CDA = 360 degrees (by adding the equations from steps 3 and 4).

Step 6: Consider quadrilateral ABED. The sum of angles in a quadrilateral is 360 degrees.

Step 7: In quadrilateral ABED, we have angle BAD + angle ABC + angle BCD + angle CDA = 360 degrees.

Step 8: Comparing steps 5 and 7, we can conclude that angle B + angle BCD + angle D = angle BAD + angle ABC + angle ADC.

Step 9: Rearranging step 8, we get angle BCD = angle BAD + angle ABC + angle ADC.

Therefore, we have proved that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.

Answer:

\(x=15/2=7.5\)

Step-by-step explanation:

So we have the equation:

\(6x-4y=29\)

And we want to find x when y is 4.

So, substitute y for 4:

\(6x-4(4)=29\)

Multiply:

\(6x-16=29\)

Add 16 to both sides:

\(6x=45\)

Divide both sides by 6:

\(x=45/6\)

Reduce by dividing both layers by 3:

\(x=15/2=7.5\)

And this is our answer :)

Answer:

\(7.5 \: or \:7\frac{1}{2}\)

Step-by-step explanation:

\(6x- 4 y = 29\\x =?\\y =4\)

Substitute 4 for y in the given equation ;

\(6x-4(4)=29\\6x -16=29\)

Collect like terms

\(6x = 29+16\)

Simplify

\(6x = 45\)

Divide both sides of the equation by 6

\(\frac{6x}{6} = \frac{45}{6} \\\\x =\frac{15}{2} \:or \: 7.5 \: or \:7\frac{1}{2}\)

The function g(x) = \(x^2\) + (2/x) has a relative minimum at (x, y), and it does not have a relative maximum.

To find the relative extrema of the function g(x), we need to find its critical points and apply the Second Derivative Test.

First, let's find the critical points by taking the derivative of g(x). The derivative of g(x) is given by g'(x) = 2x - (2/\(x^2\)). To find the critical points, we set g'(x) equal to zero and solve for x:

2x - (2/\(x^2\)) = 0

\(2x^3 - 2\) = 0

\(x^3 - 1\) = 0

\((x - 1)(x^2 + x + 1)\) = 0

From this equation, we find one critical point x = 1.

Next, we apply the Second Derivative Test to determine whether the critical point x = 1 corresponds to a relative minimum or maximum. Taking the second derivative of g(x), we get:

g''(x) = 2 + (4/\(x^3\))

Substituting x = 1 into g''(x), we find:

g''(1) = 2 + (4/\(1^3\)) = 6

Since g''(1) is positive, the Second Derivative Test tells us that the function g(x) has a relative minimum at x = 1. However, it does not have a relative maximum. Therefore, the relative minimum point is (x, y) = (1, 3).

Function notation is used to represent the area of a regular pentagon whose perimeter is 101 cm. A regular pentagon is a polygon with 5 sides and 5 equal angles. The side length, area, and perimeter of a regular pentagon are represented by the given functions. We are supposed to find the area of a regular pentagon whose perimeter is 101 cm.Since the perimeter is given, we will use the function (p) to find the side length of the pentagon, then we can use the (*) function to find its area. To find the side length of the pentagon whose perimeter is 101 cm, we will use the function (p). So, p = 101 cm. The side length of the pentagon is given by the function (p). So, a = (p/5) cm = (101/5) cm = 20.2 cm. Now, using the (*) function to find the area of the pentagon whose side length is 20.2 cm. So,* = (1/4) × √(5(5+2√5)) × (a²) cm²* = (1/4) × √(5(5+2√5)) × (20.2²) cm²= (2025√5− 810) cm².

Step-by-step explanation:

The solutions to the equation 3x^2 - 9x - 12 = 0 are x = 4 and x = -1.

To solve the quadratic equation 3x^2 - 9x - 12 = 0, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a),

where a, b, and c are the coefficients of the quadratic equation.

In this case, a = 3, b = -9, and c = -12. Substituting these values into the quadratic formula, we have:

x = (-(-9) ± √((-9)^2 - 4 * 3 * (-12))) / (2 * 3)

= (9 ± √(81 + 144)) / 6

= (9 ± √(225)) / 6

= (9 ± 15) / 6.

We have two possible solutions:

For the positive root:

x = (9 + 15) / 6

= 24 / 6

= 4.

For the negative root:

x = (9 - 15) / 6

= -6 / 6

The number of people who came to the basketball game was 75.

Given data:
The attendance at the music concert = 250 people
Attendance at a basketball game was 30% of attendance at the concert.
To find:
The number of people who attended each of the other activities.

Method:
Since the attendance at a basketball game was 30% of attendance at the concert, we can use the proportionality method to find the number of people who came to each of the other activities, as follows:

Let the attendance at the basketball game be x.  

The proportionality method is:

Attendance at basketball game / Attendance at concert = Percentage of attendance at basketball game / Percentage of attendance at concert
Putting the values in the above proportionality method, we get:
                  x / 250 = 30/100
Multiplying both sides by 250, we get:
                  x = 30/100 × 250
                  x = 75

Therefore, the number of people who came to the basketball game was 75.

Now, we can use the same method to find the number of people who came to the other activities. Let's take the drama play as an example.

Let the attendance at the drama play be y.

The proportionality method is:

Attendance at drama play / Attendance at concert = Percentage of attendance at drama play / Percentage of attendance at concert

Putting the values in the above proportionality method, we get:

y / 250 = P / 100

Where P is the percentage of attendance at the drama play.

Now, let's assume that the percentage of attendance at the drama play was 50%.

Then, putting the value of P = 50 in the above equation, we get:

y / 250 = 50 / 100

Multiplying both sides by 250, we get:

y = 50/100 × 250
y = 125

Therefore, the number of people who came to the drama play was 125.

Now, we can use the same method to find the number of people who came to the literacy night.

The predicted value of y when x = 3, based on the least-squares regression line equation y = 50 - 15x, is y = 50 - 15(3) = 5.

The given least-squares regression line equation y = 50 - 15x represents a linear relationship between the variables x and y. In this equation, the coefficient of x (-15) represents the slope of the line, and the constant term (50) represents the y-intercept.

To find the predicted value of y when x = 3, we substitute x = 3 into the equation and solve for y. Plugging in x = 3, we have y = 50 - 15(3). Simplifying this expression, we get y = 50 - 45 = 5.

Therefore, when x = 3, the predicted value of y based on the least-squares regression line is 5. This means that according to the regression line, when x is 3, the expected or estimated value of y is 5.

To fit the given points (-1,2), (0,0), (0.1,1), (1,2) to the equation y = a + bx + cx², we can use the method of least squares regression to find the values of the coefficients a, b, and c that minimize the sum of the squared differences between the actual y-values and the predicted values from the equation.

Using the least squares regression, we can solve a system of linear equations formed by substituting the x and y values from the given points into the equation. In this case, we have four equations:

2 = a - b + c

0 = a

1 = a + 0.1b + 0.01c

2 = a + b + c

Solving these equations, we find that a = 0, b = 2, and c = 0.
