Given the quadrilateral with the following vertices a(-2,3) b(-2,6) c(-6,-1) and d (-6,2). is the quadrilateral a parallelogram?
The quadrilateral is a parallelogram.
Properties of parallelogram,
a>The opposite sides of the parallelogram are equal and parallel.
b>parallel lines have an equal slope.
Let now find the length of the opposite side of the parallelogram
To find the length we have ,
[tex]\sqrt{(x_{2} ^{2} -x_{1} ^{2} ) +(y_{2} ^{2}-y_{1} ^{2} )}[/tex]
(-2, 3) , (-2, 6)
Slope = 6-3/ -2+2 = infinity
Length L1 = [tex]\sqrt{(-2 + 2)^{2} + (6 - 3)^{2} }[/tex]
= 9
(-6, -1), (-6, 2)
Slope = 2+1/ -6 + 6 = infinity
Length L2 = [tex]\sqrt{(-6 + 6)^{2} + ( 2 + 1)^{2} }[/tex]
= 9
Therefore the given vertices are of a parallelogram, as the length and slope are equal.

when g = 10
6g²
Answer:
600Step-by-step explanation:
Expression given:
6g²Find its value when g = 10:
6g² = 6(10²) = 6(100) = 600Write down the equations for the lines whose graphs are depicted below.
The equation for the lines whose graph is depicted below is y = x/2.
How to write the equations for the lines?In order to write the equations for these straight lines, we would have to determine the slope of the straight lines.
How to calculate the slope of a line?Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
From the graph (see attachment), we have the following data:
Points on x-axis = (0, 2).
Points on y-axis = (0, 1).
Substituting the given points into the formula, we have;
Slope, m = (1 - 0)/2 - 0)
Slope, m = 1/2.
Mathematically, the standard form of the equation of a straight line is given by;
y - y₁ = m(x - x₁)
At point (2, 1), we have:
y - 1 = 1/2(x - 2)
y - 1 = x/2 - 1
y = x/2 - 1 + 1
y = x/2.

the median of 6 consecutive integers is 9. what is the largest number
If the median of 6 consecutive integers is 9, the largest number is equal to 8.5.
Given the following data:
Median, M = 9.Number of consecutive integers, n = 6.What is a median?In Mathematics, a median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.
In Mathematics, the median of a data set is generally considered to be a better measure of center than the mean when there's an outlier in the data set.
For the largest number, we have:
Since consecutive integers must follow each other sequentially with a difference of 1, so the largest number is given by:
Largest number = Median + (n - 1)/2
Substituting the given parameters into the formula, we have;
Largest number = 6 + (6 - 1)/2
Largest number = 6 + (5)/2
Largest number = 6 + 2.5
Largest number = 8.5.

Answer:
y = 2x + 11
Step-by-step explanation:
To find the slope, use the equation (y2 - y1)/ (x2 - x1). You get (15 - 5)/(2 - (-3), or 2. Then, use the slope you just found in the equation y - y1 = slope (x - x1), or y - 15 = 2 (x - 2). Simplifying down you get y = 2x -4 + 15, or y = 2x + 11, which is your final answer.

Six bells commence tolling together and toll at intervals of 2, 4, 6, 8 10 and 12 seconds respectively. if they toll together at 11:00, at what time will they toll together again?
If Six bells commence tolling together and toll at intervals of 2, 4, 6, 8 10, and 12 seconds respectively and toll together at 11:00, then they will toll together again at 11:02.
Least common multiple abbreviated as LCM is used to determine the time at which the six bells will toll together again.
The least common multiple of two or more numbers is the smallest number that is a multiple of those numbers.
The least common multiple of 2, 4, 6, 8, 10, and 12 can be found by prime factorization.
Prime factorization of :
2 = 2^1
4 = 2 x 2 = 2^2
6 = 2 x 3
8 = 2^3
10 = 2 x 5
12 = 2 x 2 x 3 = 2^2 x 3
The least common multiple can be calculated by the multiplication of the prime factors raised to their highest power.
Therefore,
LCM = (2^3) (3) (5) = 120
Hence the bells will toll together again after 120 seconds
As 120 seconds = 2 minutes
Therefore, the time at which they will toll together again is calculated to be 11:02.

Answer:
See the table below
For n, the answer is 2n+1
Step-by-step explanation:
The number of trees in each figure represents an arithmetic sequence where the difference between subsequent figures is 2 (caled the common difference)
So the sequence is
Figure(n) Number of Trees
1 3
2 5
3 7
4 9 (7+2)
5 11 (9+2)
n 2n + 1
In general, for any arithmetic sequence we can write an equation for the nth term as [tex]a_n = a_0 + d(n-1)[/tex] where [tex]a_0[/tex] is the first term and d is the common difference
So for this example, we have [tex]a_0 = 3[/tex] and d=2 giving

The correct option is A. x = 1(1/3) and y = 2(1/3) in the mixed fractions.
What is defined as the system of equations?A system of equations is a collection of equations that all have the same variables.
If all of the equations are linear, you get a system of linear equations! To fix a system of equations, you must first determine the variable values that will solve all of the equations involved.A solution to an equation system is a set of variable values that satisfy all of the equations at the same timeNow, the given equation in the question are-
7x - y = 7 ........(equation 1)
and x + 2y = 6 ........(equation 2)
Multiplying both side of equation 1 with 2, we get
14x - 2y = 14 ........(equation 3)
Add equation 2 and 3.
x + 2y + 14x - 2y = 6 + 14
15x = 20
x = 4/3
x = 1(1/3)
Substitute the value of x in equation 1.
4/3 + 2y = 6
2y = 6 - 4/3
2y = 14/3
y = 7/3

A probability distribution showing the probability of x successes in n trials, where the probability of success does not change from trial to trial, is termed a.
For a continuous distribution, the uniform distribution describes equal probability over a specific range. It is crucial as a reference distribution because of this. The creation of random numbers is one of the uniform distribution's most significant uses.
A particular probability distribution is called a binomial distribution. It is used to simulate the likelihood of getting one of two results out of a certain number of trials (N) of a discrete random event.
The expected outcome is referred to as a success in a binomial distribution, whereas any other event is referred to as a failure. A successful outcome has a probability of p, while a failure has a chance of 1 - p.
In n draws without replacement from a finite population of size N that contains exactly K objects with that feature, the hypergeometric distribution, a discrete probability distribution, describes the likelihood of k successes (random draws for which the drawn object has a specified feature), where each draw is either successful or unsuccessful. The binomial distribution, on the other hand, describes the likelihood of k successes in n draws with replacement.
The normal distribution sometimes referred to as the Gaussian distribution, is a probability distribution that is symmetric about the mean and demonstrates that data that are closer to the mean are more likely to occur than data that are farther from the mean. The normal distribution is depicted graphically as a "bell curve."
The correct option is (b) binomial probability distribution.
