Answer: The probability of the pointer lands on red(R) both spin =

Step-by-step: The number of parts = 6

The pointer is spun twice.

To find the probability of the pointer lands on red(R) both spin.

Formula

Probability of an event = number of required outcomes ÷ the total number of outcomes.

P(A and B) = P(A)×P(B)

Now,

For one spin,

A = RED comes.

For second spin,

B = RED comes

So,

P(A) = and P(B) =

Then,

P(A and B) = × =

Hence, the probability of the pointer lands on red(R) both spin =

The solution for the given equation 3x-9y=72 is x = 3y + 24.

What is equation?

An equation is a mathematical statement that asserts the equality of two expressions. It contains variables, constants, and mathematical operators such as addition, subtraction, multiplication, division, and exponentiation.

To find the solution for the equation 3x - 9y = 72, we need to solve for one variable in terms of the other variable and then substitute the expression back into the equation to solve for the remaining variable.

Step 1: Solve for x in terms of y:

3x - 9y = 72

3x = 9y + 72

x = 3y + 24

Step 2: Substitute the expression for x into the original equation:

3x - 9y = 72

3(3y + 24) - 9y = 72

9y + 72 - 9y = 72

72 = 72

Step 3: Check the solution:

Since the equation simplifies to a true statement, 72 = 72, the solution is consistent with the original equation.

Step 4: Write the solution:

The equation 3x - 9y = 72 has infinitely many solutions, which can be expressed in terms of y as:

x = 3y + 24, where y is any real number.

The area of the region bounded by the curve r = θ² and the sector 0 ≤ θ ≤ π/3 is π⁵/8100

The exact length of the polar curve r = θ² for 0 ≤ θ ≤ 5π/4, we can use the arc length formula for polar curves:

L = ∫[a, b] √(r(θ)² + (dr(θ)/dθ)²) dθ

In this case, we have r(θ) = θ². To find dr(θ)/dθ, we differentiate r(θ) with respect to θ:

dr(θ)/dθ = 2θ

Now we can substitute these values into the arc length formula:

L = ∫[0, 5π/4] √(θ⁴ + (2θ)²) dθ

= ∫[0, 5π/4] √(θ⁴ + 4θ²) dθ

= ∫[0, 5π/4] √(θ²(θ² + 4)) dθ

= ∫[0, 5π/4] θ√(θ² + 4) dθ

This integral does not have a simple closed-form solution. It would need to be approximated numerically using methods such as numerical integration or numerical methods in software.

For the second part, to find the area of the region bounded by the curve r = θ² and the sector 0 ≤ θ ≤ π/3, we can use the formula for the area enclosed by a polar curve:

A = 1/2 ∫[a, b] r(θ)² dθ

In this case, we have r(θ) = θ² and the sector limits are 0 ≤ θ ≤ π/3:

A = 1/2 ∫[0, π/3] (θ²)² dθ

= 1/2 ∫[0, π/3] θ⁴ dθ

= 1/2 [θ⁵/5] | [0, π/3]

= 1/2 (π/3)⁵/5

= π⁵/8100

Therefore, the area of the region bounded by the curve r = θ² and the sector 0 ≤ θ ≤ π/3 is π⁵/8100.

I have sacrificed my self for the greater good of helping others beat the beast known as edge2020

The cheetah can travel 74.6 miles in 1 hour at its top speed.

To determine how far a cheetah can travel in 1 hour, we need to use the information provided and make some calculations.

First, we know that the cheetah can travel at its top speed for 1.5 hours, covering a distance of 111.9 miles. This means that we can calculate the cheetah's average speed during this time as follows:

Average speed = Distance covered / Time taken

Plugging in the values, we get:-

Average speed = 111.9 miles / 1.5 hours = 74.6 miles/hour

This means that the cheetah can run at an average speed of 74.6 miles per hour.

Now, to determine how far the cheetah can travel in 1 hour, we can use the formula:

Distance = Speed x Time

Plugging in the values, we get:-

Distance = 74.6 miles/hour x 1 hour = 74.6 miles

Therefore, the cheetah can travel 74.6 miles in 1 hour at its top speed.

The solution of the given system of equations 8x+3y=5 and 3x-2y=5 is x = 1 and y = -1

In this question we have been given a system of equations.

8x+3y=5                 ..........(1)

and 3x-2y=5           ..........(2)

We need to find the solution of the given system of equations.

As right hane side of both equations is equal, we equate LHS of both equations.

so, we get,

8x + 3y = 3x - 2y

⇒ 8x - 3x = - 2y - 3y

⇒ 5x = - 5y

⇒ x = - y                      .............(3)

By substituting x = - y in equation (1), we get,

8 ( - y ) + 3y = 5

⇒ - 8y + 3y = 5

⇒ - 5y = 5

⇒ y = - 1

Substitute above value of y in equation (3)

⇒ x = - (- 1)

⇒ x = 1

Therefore, x = 1 and y = -1 is solution of given equations.

Step-by-step explanation:

The length of each of its sides is 12 inches if the perimeter of a regular hexagon is 72 inches option (B) is correct.

A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.

\(\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|\)

It is given that:

The perimeter of a regular hexagon is 72 inches.

P = 6a

Here P is the perimeter and a is the side length of the hexagon

72 = 6a

The given statement "The this pointer is not automatically passed to static member functions of a class." is false as static member functions can be called without creating an object of the class, and the "this" pointer is used to refer to the current instance of the class. Since no instance is required for static member functions, the "this" pointer is not applicable in this case.

In object-oriented programming, a class is a blueprint for creating objects, and member functions are functions defined within a class that can be called on objects of that class.

Static member functions, also known as class methods, are special member functions that are associated with the class itself rather than any specific object or instance of the class. They are declared using the "static" keyword.

Since static member functions do not operate on specific instances of the class, they do not have access to the "this" pointer. The "this" pointer is a hidden pointer that points to the current object instance, allowing non-static member functions to access the data members and other member functions of the object. However, static member functions do not have this pointer because they are not tied to any specific object.

Static member functions can only access static members of the class, which include static variables and other static member functions. They can be called using the class name itself, without creating an instance of the class. This is because they are not associated with any particular object but rather with the class as a whole.

The gate code to a gated community consists of the # key, followed by 3 letters chosen from the English alphabet, followed by 3 digits. The total number of possible gate codes is 17.576,000.

To find the total number of possible gate codes for the gated community, we need to determine the number of choices for each part of the code and multiply them together.
1. The gate code starts with the # key, which is constant, so there's only 1 choice for this part.
2. The next part consists of 3 letters chosen from the English alphabet. There are 26 letters in the alphabet, and each of the 3 positions can be filled with any of those letters. So, the number of choices for this part is 26 * 26 * 26.
3. The last part of the code consists of 3 digits. Since there are 10 digits (0-9), there are 10 choices for each digit. Therefore, there are 10 * 10 * 10 choices for this part.
Now, we'll multiply the number of choices for each part together to get the total number of possible gate codes:
1 * (26 * 26 * 26) * (10 * 10 * 10) = 1 * 17576 * 1000 = 17,576,000

There exists a sequence with a bounded subsequence but no convergent subsequences.

In mathematics, it is possible to have a sequence that contains a subsequence which is bounded but does not have any subsequence that converges. This means that although there are elements within the sequence that are limited within a certain range, there is no specific subsequence that approaches a definite value or limit.

To construct such a sequence, one approach is to alternate between two subsequences. Let's consider an example: {1, -1, 2, -2, 3, -3, ...}. Here, the positive terms form a subsequence {1, 2, 3, ...} which is unbounded, and the negative terms form another subsequence {-1, -2, -3, ...} which is also unbounded. However, no subsequence of this sequence converges because it oscillates between positive and negative values.

Therefore, this example demonstrates a sequence that contains a bounded subsequence but lacks any convergent subsequences.
