The values of a, b, c, and d, based on the given equation are:
\(a = 10\\b = 3\\c = -6\\d = -5\)
Let's calculate the values of a, b, c, and d based on the given table:
Using the equation \(y = x^2 - 4x - 2\), we can substitute the values of x and find the corresponding values of y:
For x = -3:
\(y = (-3)^2 - 4(-3) - 2 = 9 + 12 - 2 = 19\)
For x = -2:
\(y = (-2)^2 - 4(-2) - 2 = 4 + 8 - 2 = 10\)
For x = -1:
\(y = (-1)^2 - 4(-1) - 2 = 1 + 4 - 2 = 3\)
For x = 0:
\(y = (0)^2 - 4(0) - 2 = 0 - 0 - 2 = -2\)
For x = 1:
\(y = (1)^2 - 4(1) - 2 = 1 - 4 - 2 = -5\)
For x = 2:
\(y = (2)^2 - 4(2) - 2 = 4 - 8 - 2 = -6\)
For x = 3:
\(y = (3)^2 - 4(3) - 2 = 9 - 12 - 2 = -5\)
Now let's match these values with the table:
\(x , y = x^2 - 4x - 2\)
\(\[\begin{align*}(-3, 19) \\(-2, a) \\(-1, b) \\(0, -2) \\(1, -5) \\(2, c) \\(3, d) \\\end{align*}\]\)
From the given table, we have:
\(a = 10\\b = 3\\c = -6\\d = -5\)
Certainly! Here's a 100-word explanation of the given data:
The data provided consists of pairs of values, where the first column represents the x-values and the second column represents the y-values. Each row in the table corresponds to a data point. For instance, when x is \(-3\), the corresponding y-value is \(19\). Similarly, when x is \(-2\), the y-value is denoted as '\(a\)', and when \(x\) is -\(1\), the \(y\)-value is denoted as 'b'.
The pattern continues for the remaining data points, with specific values assigned to \(x \ and \ y\). This data set allows for the representation and analysis of relationships between the variables \(x \ and \ y\).
Therefore, the values of a, b, c, and d are:
\(a = 10\\b = 3\\c = -6\\d = -5\)

Answers
An \(11\)-vertex full graph has around \(19,958,931,200\) Hamiltonian circuits in a complete graph.
Describe the Hamiltonian circuit with an example.At one vertex, the Hamiltonian route begins, and at another, it finishes. Yet, when following a Hamiltonian route, every vertex is encountered. At the same vertex, the Hamiltonian circuit begins and terminates. For instance, if a Hamiltonian circuit's path began at vertex 1, the loop will also conclude at that vertex.
The Hamiltonian circuit: what is it?Single circuit is the sole trip a Hamiltonian circuit makes to each vertex. It must begin and terminate at same vertex since it is a circuit. A Hamiltonian route does not start and end in a single location, but it does visit each vertex just once with no repetitions.
We have to divide by \(2(n-2)\)
\(11!/(2(11-2)!) = 11!/2,520\) Hamiltonian circuits we get:
\(11!/2,520 = 19,958,931,200\)

Given
\(-2x-2y=8\)To find a solution for the linear equation, the first step is to write the equation in slope-intercept form:
-Pass the x-term to the right side of the equation by applying the opposite operation to both sides of the equal sign:
\(\begin{gathered} -2x+2x-2y=8+2x \\ -2y=2x+8 \end{gathered}\)-Divide both sides by -2:
\(\begin{gathered} \frac{-2y}{-2}=\frac{2x}{-2}+\frac{8}{-2} \\ y=-x-4 \end{gathered}\)Once you have expressed the equation of the line in slope-intercept form, replace it with any value for x and calculate the corresponding value of y, for example, x=2

Alessia’s salary in 2022 was 26,000 after tax.
She spends 35% of her after tax salary on rent.
The rest is split between food, petrol and entertainment in the ratio 6:11:8
Work out how much alessia spent on entertainment in 2021
Answers
Alessia spent $5,408 on entertainment in 2021.
To determine how much Alessia spent on entertainment in 2021, we need to work backward from the given information about her salary in 2022.
Let's assume Alessia's salary in 2021 was the same as in 2022, which is $26,000 after tax.
Since Alessia spends 35% of her after-tax salary on rent, we can calculate her rent expenditure:
Rent = 35% × $26,000
= $9,100
The remaining amount is split between food, petrol, and entertainment in the ratio 6:11:8.
To determine the ratio's total parts, we sum the individual parts:
Total parts = 6 + 11 + 8 = 25
Next, we calculate the value of one part of the ratio:
One part = ($26,000 - $9,100) / 25
= $16,900 / 25
= $676
Now, we can calculate how much Alessia spent on entertainment in 2021, which is 8 parts of the ratio:
Entertainment expenditure = 8 × $676
= $5,408

Find the perimeter of an equilateral triangle with an alititude of 18 inches
Answers
the perimeter of the equilateral triangle with a side length of 12√3 is 36√3 units.
In order to find the perimeter of the given triangle, we have to find the side of the triangle. The altitude of the triangle = 18 inches. Let us assume the side of the triangle as a. The formula for calculating the altitude of an equilateral triangle is : Altitude =√3/2×a (side)
18 =√3/2 × a
a = 18 × 2√3
a = 36√3
a = 36 ×√3 / √3×√3
a =36√3/3
a = 12√3 inches.
If the side of an equilateral triangle is 12√3, then all three sides of the triangle are of equal length, since it is an equilateral triangle. Therefore, the perimeter of the triangle is simply the sum of the lengths of its three sides. Since each side of the triangle has a length of 12√3, the perimeter is: Perimeter = 3 x (12√3) = 36√3.
Therefore, the perimeter of the equilateral triangle with a side length of 12√3 is 36√3 units.

if the odds on a bet are 41:1 against, what is the probability of winning? express your answer as a fraction.
Answers
The probability of winning is 1/42 expressed as a fraction.
Given that the odds on a bet are 41:1 against, we are to find the probability of winning.
We know that odds against = (Number of unfavorable outcomes) : (Number of favorable outcomes).
Thus, odds against = 41:1. This implies that the number of unfavorable outcomes is 41 and the number of favorable outcomes is 1.Probability of winning is given by the formula P(winning) = Number of favorable outcomes / Total number of possible outcomes. In this case, the total number of possible outcomes is the sum of the number of favorable and unfavorable outcomes.
Number of favorable outcomes = 1 and Number of unfavorable outcomes = 41
Therefore, the total number of possible outcomes = 1 + 41 = 42
Thus, P(winning) = Number of favorable outcomes / Total number of possible outcomes
P(winning) = 1 / 42
Therefore, the probability of winning is 1/42 expressed as a fraction.

A train took 11. 5 minutes to travel 10 km from station X to station Y. It stopped at station Y for 0. 5 minutes. It then took another 24. 0 minutes to travel 20 km from station Y to station Z. What was the average speed of the train (km/hr)? (Please show all statements and working to get full marks) 3 marks
Answers
The average speed of the train can be calculated by dividing the total distance traveled by the total time taken. In this case, the train traveled a total distance of 30 km (10 km from X to Y + 20 km from Y to Z) and took a total time of 36 minutes (11.5 minutes + 0.5 minutes + 24 minutes). Converting the time to hours (36 minutes = 0.6 hours), the average speed of the train is 50 km/hr.
To calculate the average speed of the train, we need to divide the total distance traveled by the total time taken. Let's calculate each component:
1. Total distance: The train traveled 10 km from station X to station Y and then an additional 20 km from station Y to station Z, making a total distance of 30 km.
2. Total time: The train took 11.5 minutes to travel from X to Y, stopped at station Y for 0.5 minutes, and then took another 24.0 minutes to travel from Y to Z, making a total time of 11.5 minutes + 0.5 minutes + 24.0 minutes = 36 minutes.
To convert the total time to hours, we divide it by 60 (since there are 60 minutes in an hour): 36 minutes / 60 = 0.6 hours.
Finally, we can calculate the average speed by dividing the total distance (30 km) by the total time in hours (0.6 hours): 30 km / 0.6 hours = 50 km/hr.
Therefore, the average speed of the train is 50 km/hr.

Answers
The equation of the line in point-slope form is y - 5 = -7(x + 1) and in slope-intercept form is y = -7x - 2.
The equation of a line in point-slope form is given by y - y₁ = m(x - x₁), where (x₁, y₁) represents a point on the line and m is the slope of the line.
Given that the slope (m) is -7 and the point (-1, 5) lies on the line, we can substitute these values into the point-slope form equation:
y - 5 = -7(x - (-1))
Simplifying:
y - 5 = -7(x + 1)
y - 5 = -7x - 7
y = -7x - 2
So, the equation of the line in point-slope form is y - 5 = -7(x + 1) and in slope-intercept form is y = -7x - 2.
