Write a function to represent the set of ordered pairs.
{(2, -1), (4, 5), (6, 15), (8, 29)}
Answers
Step-by-step explanation:
ES6 has a new Set data structure for storing sets of unique objects. However it is based on object references as opposed to value comparisons. As far as I can tell this makes it impossible to have a set of pairs of numbers without stringifying.
For example, typing in Chrome's console (needs Chrome 38+):
> var s = new Set(); < undefined > s.add([2, 3]); < Set {[2, 3]} > s.has([2, 3]) < false <--- was hoping for 'true'
This appears to be by design: since I passed a different array of [2, 3] to has(), it returns false, because although the contents is the same it only looks at object references, and I allocated a new and different array to pass to has(). I would need to store a reference to the original array I passed to add() to check with has(), but this is not always possible. For example if the number pairs represent co-ordinates, I might need to check if the set has [obj.x, obj.y], but this will always return false since it allocates a new array.
The workaround is to stringify the arrays and key on strings like "2, 3" instead. However in something performance-sensitive like a game engine, it is unfortunate if every set access needs to make a string allocation and convert and concatenate number strings.
Does ES6 provide any feature to solve this problem without stringifying, or is there any feature on the horizon with ES7 that could help as well?

As you've noted [2, 3] === [2, 3] is false, meaning you can't use Set like this; however, is Set really the best option for you?
You may find that using a two-level data structure like this will be better for you
var o = {}; function add(o, x, y) { if (!o[x]) o[x] = {}; o[x][y] = true; } function has(o, x, y) { return !!(o[x] && o[x][y]); } function del(o, x, y) { if (!o[x]) return; delete o[x][y]; // maybe delete `o[x]` if keys.length === 0
Is (5,2) a solution to this system? x+4y=13 x-y=3 *
Answers
Answer:
yes
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
x + 4y = 13
x - y = 3 Subtracting:
0 + 4y - (-y) = 13 - 3
5y = 10
y = 2.
Plug y = 2 into the second equation:
x - 2 = 3
x = 5.

Answer:

Step-by-step explanation:
A tax is a compulsory sum levied by the government or an agency of the government on goods and services. Taxes increase the price of good. The items bought would increase by 8%
Tax paid by Dave = 0.08 x $15 = $1.2
total price paid by Dave = 1.2 + $15 = $16.2
Tax paid by Mel = 0.08 x $20 = $1.6
total price paid by Mel = $20 + $1.6 = $21.60
Difference in prices
21.6 -16.2 = $5.40

A student need to fill a tank with 9 liters of water. How many 1/3 liters will it take to fill the tank?
Answers
Answer:
Number of [tex]\frac{1}{3}[/tex] liters required to fill the tank = 27
Step-by-step explanation:
Amount of water needed to fill the tank = 9 liters
Measure of water to fill a vessel = [tex]\frac{1}{3}[/tex] liters
Number of [tex]\frac{1}{3}[/tex] liters vessels required to fill the tank = [tex]\frac{9}{\frac{1}{3}}[/tex]
= 9 × [tex]\frac{3}{1}[/tex]
= 27
Therefore, number of [tex]\frac{1}{3}[/tex] liters required to fill the tank = 27

у = х + 3

Answers
Answer:
x = - 2, y = 1
Step-by-step explanation:
Comparing both the equations,
→ y = y → x + 3 = - 2x - 3
=> x + 3 = - 2x - 3
=> x + 2x = - 3 - 3
=> 3x = - 6
=> x = - 6/3 = - 2
Substitute the value of x in any of these:
=> y = x + 3 = - 2 + 3 = 1
Answer:
Step-by-step explanation:
If a solution exists for the system of equations y=y so we can say
x+3=-2x-3 Add 2x to each side
3x+3=-3 Subtract 3 from each side
3x=-6. Divide each side by 3
x=-2, since y=x+3
y=-2+3
y=1
So the solution to the system of equations is the point (x,y)=(-2,1)

Answer:
68.9°
Step-by-step explanation:
Using Sine rule
x/sin X = y/sin Y
4.5/sin X = 4/sin 56
sin X × 4 = 4.5 × sin 56
sin X = 4.5 × sin 56/4
X = arc sin (4.5 × sin 56/4)
X = 68.85449°
Approximately = 68.9°

You have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long. How many feet of streamers do you have left?
Answers
Answer:
48
Step-by-step explanation:
If we have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long then 48 feet of streamers we left.
What is Unit of Measurement ?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
Given that we have a 84 feet of streamers.
You cut 24 pieces that are each 1/2 yard long.
Need to find the feet of streamers we left.
We know that 1 yard is equal to 3 feet.
Therefore, 1/2 yard is equal to 1.5 feet.
The total length of the streamers that were cut is:
24 pieces x 1.5 feet/piece = 36 feet
To find out how much streamer is left, we can subtract the length of the cut streamers from the total length we started with:
84 feet - 36 feet = 48 feet
Therefore, you have 48 feet of streamers left.
