The coordinate A , B and C will be A(2,2), B(2,6) and C(10,2)

A coordinate system is a method for determining how to position points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more integers, or coordinates.

In order to make it simple to identify the points, a cartesian plane divides the plane space into two dimensions. The coordinate plane is another name for it. The horizontal x-axis and the vertical y-axis are the two axes of the coordinate plane. The origin is the place where these coordinate axes connect, and they split the plane into four quadrants (0, 0). Additionally, each point in the coordinate plane is denoted by the coordinates (x, y), where x represents the point's location in relation to the x-axis and y represents its position in relation to the y-axis.

Since it is factored by 2

The coordinate A , B and C will be

A (1*2, 1*2) = A(2,2)

B(2,6) and C(10,2)

Our Pythagorean triplets will be (3,4,5) and (6,8,10).

So what is the Pythagorean triplet?

The square of the greatest number in a Pythagorean triplet equals the sum of the squares of the other two numbers.

The greatest side in a right-angled triangle is called the hypotenuse.

So, in our first triplet (3,4,5) the greatest side is 5. So, hypotenuse = 5.

=  [tex]hypotenuse^{2}[/tex] = [tex]5^{2}[/tex] = 25.

Now, [tex]3^{2}[/tex] + [tex]4^{2}[/tex] = 9 + 16 = 25.

So, [tex]5^{2}[/tex] = [tex]3^{2}[/tex] + [tex]4^{2}[/tex].

Thus (3,4,5) is a Pythagorean triplet.

In the second case (6,8,10) hypotenuse = 10.

= [tex]hypotenuse^{2}[/tex] = [tex]10^{2}[/tex].

Now, [tex]6^{2}[/tex] + [tex]8^{2}[/tex] = 36 + 64 = 100.

So, [tex]10^{2}[/tex] = [tex]6^{2}[/tex] + [tex]8^{2}[/tex].

Thus (6,8,10) is a Pythagorean triplet.

In the Third case (8,10,12) Hypotenuse = 12.

= [tex]hypotenuse^{2}[/tex] = [tex]12^{2}[/tex] = 144.

Now, [tex]8^{2}[/tex] + [tex]10^{2}[/tex] = 64 + 100 = 164.

So, [tex]12^{2}[/tex] [tex]\neq[/tex] [tex]8^{2}[/tex] + [tex]10^{2}[/tex].

Thus (8,10,12) is not a Pythagorean Triplet.

Therefore our two results (3,4,5) and (6,8,10) are Pythagorean triplets.

Total cost of dinner including tip = $861.40

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given

Cost of the dinner = $730

Amount tipped to the caterers = 18% of 730

                                                   = 18/100 × 730

                                                   = $131.40

Total cost of dinner = 730 + 131.40

Total cost of dinner = $861.40

Answer: 4x+y-6=0

Step-by-step explanation:

To find the equation of the line that is parallel to 4x+y+1=0, we need to work in terms of slope-intercept form, which is y=mx+b.

4x+y+1=0       [subtract both sides by 4x]

y+1=-4x          [subtract both sides by 1]

y=-4x-1

Our original equation is in terms of y=mx+b.

The properties of parallel lines is that they NEVER touch. Therefore the slope must be the same. The y-intercept can be different though.

y=-4x+b           [plug in (1,2)]

2=-4(1)+b          [multiply]

2=-4+b             [add both sides by 4]

b=6

We can fill in our equation now.

y=-4x+6

We need to make our equation match the original, so let's manipulate it.

y=-4x+6           [add both sides by 4x]

4x+y=6            [subtract both sides by 6]

4x+y-6=0

Therefore 4x+y-6=0 is the answer.

x and y​ are not proportional and the value of the card in 2011​ is $33.14.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

Given that, when he retired in 2000 his card was worth ​$7.73. The value has increased by ​$2.31 each year since then.

Let the value of the card y in dollars and the number of years x the player has been in retirement.

Now equation is y=7.73+2.31x

When x=1

y=$10.04

When x=2

y=7.73+2.31(2)

y=$12.35

When x and y are proportional

1/10.04 ≠2/12.35

The given table is about the times recorded on the timesheet for the week.

We have to calculate the total time she worked for.

From 7:05 to 3:58

If 7:05 is a.m. then 3:58 will be 15:58 pm.

By subtraction of these timings we can get the number of hours she has worked.

15:58 - 07:05 = 8:53 (8 hours 53 minutes)

From 7:30 a.m. to 17:01 pm

17:01 - 07:30 = 9:31 (9 hours 31 minutes)

From 8:01 a.m. to 17:32 pm

17:32 - 08:01 = 09:31 ( 9 hours 31 minutes)

From 07:22 a.m. to 16:46 pm

16:46 - 07:22 = 09:24 (9 hours 24 minutes)

From 6:55 am to 16:31 pm

16:31 - 06:55 = 9:36 (9 hours 36 minutes)

Therefore, total time she worked = 8:53 + 9:31 + 9:31 + 9:24 + 9:36 = 44:175 (44 hours 175 minutes)

Now we will convert minutes to hours

175 minutes = 2 hours 55 minutes

So total working hours = 44 hours + 2 hours 55 minutes = 46 hours 55 minutes ≈ 47 hours

To meet, Armand and Jill will both travel for an equal length of time.

50t + 60t = 247.5 is the formula used to calculate the time, t, required for their meeting.

To meet Armand, Jill will travel 135 miles.

given that

Despite being 247.5 miles apart, Armand and Jill are heading in the same direction.

50 mph is the speed at which Armand is moving.

and Jill's vehicle is moving at a 60 mph pace.

Allow them to connect after t hours.

We understand that Distance=Speed*Time.

Armand traveled 50 miles, thus.

Jill traveled 60 t of distance.

Now that they are moving in that direction, do the following:

50t+60t=247.5--------------

(a)

1)To meet, Armand and Jill will both travel the same distance.

The value of 50t and 60t will differ for the same t, hence this statement is false.

2)Jill and Armand will both travel for an equal length of time to meet.

This is accurate because they will collide at the same time.

3)50t + 60t = 247.5 is the formula used to determine how long it will take for them to meet.

This statement is true.

4)They won't meet until 4.5 hours have passed.

We will calculate the value of t using equation (a) and determine if t=4.5 or not.

As 50t+60t=247.5

⇒ 110t=247.5

⇒ t=247.5/110=2.25

As a result, it will take 2.25 hours for them to finally meet.

Option 4 is therefore unsuitable.

5)To meet Armand, Jill will travel 135 miles.

One common trick for memorizing the 8 times table is to pair it with the 4 times table.

For example, 8 x 4 = 32, so 8 x 5 = 40 because 5 is one more than 4. Similarly, 8 x 6 = 48 because 6 is two more than 4, and so on. Another trick is to think of it as 8 x 10 = 80 and then subtract 8. For example, 8 x 7 = 80 - 8 = 72.

The eight times table trick states that when you multiply eight by a number between one and five, the result always begins with a digit one lower than the number from one to five.

An example of a pattern rule is "add 3" which means that to find the next term in a sequence, you add 3 to the previous term.

A pattern rule is a mathematical relationship used to find the value of each term in a sequence. To describe certain sequences, a pattern rule can be established. This is an algebraic equation that enables you to quickly find the value of a term in a sequence using its rank.

To write a rule for a sequence, you need to identify the pattern. This involves looking at the differences between the numbers and seeing if there is a pattern of increasing or decreasing numbers. Once you have identified the pattern, you can then write a rule that expresses that pattern.

Examples of pattern sequences include the Fibonacci sequence (1,1,2,3,5,8,13,21,34, etc.), the even numbers (2,4,6,8,10, etc.), and the multiples of 3 (3,6,9,12,15, etc.).

To describe the pattern of a sequence, you need to look at the differences between the numbers and the pattern of increases or decreases. For example, in the Fibonacci sequence, the pattern is that each number is the sum of the two numbers before it so 1+1=2, 1+2=3, 2+3=5, etc.
