The numbers after 3(2012) and 716000 are the increased amount of the numbers. To do that, I added another 4 years to the latest year, which is 2012. So I added 4 to 2012(4+2012=2016). (2016=4th year) So, to find the total saving of the savings, I used the equation to find it.
As the data shows, in each year the savings of the water increase by 23,300million liters. Since the linear pattern shows that the savings increase by 23,300 or decrease by 23,300.
93,200=23,300 x 4
At last, I got 94,900 for the total savings for 2016. To get the next answer, I just had to change the number for n. If I want to get next four year savings, I just have to add 1 to the latest number of n(which is 4, so 4+1=5).
n= number of years after the years 2000
s=represents the savings
RATE OF CHANGE:
Equation: s= 5825n+1700
The Rate of change is 5825
Initial value is 1700
The Rate of change is 5825 because when the second number on the table is subtracted from the first number, 5825 is the answer and because it is a pattern the rest of the table is the same(5825).
Initial value is 1700 because 1700 is the first number that starts on the graph, and also it is 0-1700, which means that even if there were no “Years” it would still be 1700L saved.
Interpolation:The rate of change is 5825, which meant the initial value would be 1700. Every year that passes by the savings go up by 5825L (each year).So if you looked at 2001 and 2002 you can see that the savings of water have increased by 5825L,13350-7525=5825.
Exploitation:Since in the year part of my table goes up by 1 year at a time to get more data of how much savings of water there will be in the future all you need to do it add 5825 from the latest piece of data on the table.
Example: year- 2004 (4)
19175 (<- the latest piece of data on the table) + 5825=25000
so in the year 2004 the water saving would be 25000L
Patterns I see In my data is, for every year the savings increase by 5825million L in savings, Every year it increases by 5825 million L savings because its a linear piece of data so per every year it had to increase or decrease by a certain amount and this table and graph increases by 5852 million liters
In this Image I don't see any patterns since it doesn't not continue and it is not a linear pattern. This Images data is different from the linear pattern I got in part 1 because in this image it talks about the total water usage, and in my linear pattern it talks about water saving per year, the similarities are that they both talk about syne and Water usage/savings.
This graph patterns I see are almost all of these cities only have a small percentage of recycled water, and only the most of the water from these cities come from surface waters. Between this graph and the linear patters I got in part 1 is different because even though both graph/tables talk about water in the same city but this graph talks about where the water comes from and my linear patter is about water savings
This In the year of 2001, about 10 000 liters were recycled. On next year, around 11 000 liters of water was recycled and in the next year it reused 12,600 liters of water. Every year, the amount of water was recycled even more.
In the year of 2000, 2001 , there was only residential indoor and leakage reduction to be seen. However, in the year of 2002, there seemed to be residential outdoor to be involved. In the year of 2003, 2004 and 2005, there was another thing called, recycled water. Because of recycled water, there seemed to be less impacts on the places. As the years passed the leakage reduction, regulatory measure, recycled water, business program, and regulatory indoor increased.
-The population of Sydney has increased by doubling. Now, the total population is 4,284,379. So, when in the year of 2031, 20% of the consumption of water is will increase.
-Every year, the Australians use huge amount of water and that much amount of water can fill Sydney water 48 times.
-Around 9% of water is mostly used for drinking and other personal things. Also most of the piped water(70%) is used. Later, when water is useless, the water gets thrown away to the ocean.
-In one day, 92 million liters of water is being recycled by Sydney water. By recycling the waters, the amount of the water producing is reducing. It is less likely to waste lots of water. The water is being being recycled in many different ways.
-The time when the water leaked in 2008-2009, it was guessed to be amount of 105 million liters a day. That was a result of 7.3% total amount of water used. The water leakage had huge impact to the world.
-In the year of 2008 and 2009, Sydney Water have recycled 25,442 million liters of dirty water. Also, from Sydney water, more than 5% of dirty was collected. That happened because the Sydney water started a new system to recycle the wastewater in the places.
-The Sydney water runs 16 recycled projects and it is related to lots of other project. Such as, “residential dual reticulation scheme at Rouse Hill”, the “Wollongong Recycled Water Scheme”. The projects are related to suppling the recycled water for many different types of uses. They are used for manufacturing uses, farming, public uses, fields and etc.
-Sydney Water products 1.4 billion litres of water. Most of the waters are producted for the households. They are supplied daily to lots of places, they are supplied to homes and businesses. 72% of the water are supplied for the households and 28% of other production is used for businesses.
-During past years, the use of the water increased to 6.2 million liters of water. However, in the year of 1995 in a maximum of 25% recycled water increased in a year. As a result, in the year of 2015, the recycled water should have increased to 70 billion of water.
Within the last six years leakage has gone from 188 million liters a day to around 105 million liters a day.
During a leakage that happened in 2008/2009, around 38.4 billion liters or 105 million liters leaked per day. Around 7.3%f total drinking water drawn, which is the woes that was ever recorded.
Through recycling water 10014 millions of liters is saved, company that invested in water recycling go up by 145%.
Australia only appeared in the year of 2002. Also it was the country that seemed to not appear long time and the placement of Australia didn’t increase either. The graph results matched that was in the excel graph. Australia was one of the smallest circle to be seen in the graph.
When Earth will run out of water:
Right now on Earth there is around 1,260,000,000,000,000,000,000 liters of water remain on earth(326 million trillion gallons), if we use around 3400 of liters of water everyday (including cooking, showers etc.). The world has roughly 7 billion people in the world, but since around one -third of the world doesn't have access to water which leaves us with 5.7 billion people in the world that have access to water. If we multiply 5.87billion to 3400 we get 1938000000,so that means everyday the would used approximately 1938000000 Liters of water is used every day. So if we continue with the same rate, the Earth will probably run out of water in 65015479.8761 years, but because every year the earth is getting more and more populated, it will probably be sooner than 65015479.8761 years. But scientifically the earth shouldn't end up water less, because at some point the water goes back to the environment.
"What are the governments and the world currently doing in regards to your topic?"
The governments are trying to reduce and recycle the wastewater in their countries. They tried many different types of projects to reduce the waste water. They also recycled the wastewater by using them for different uses. They can be used for flushing the toilet, watering plants, personal uses in home, and etc. They can be used well when they are purified. So, lots of countries are trying to reuse them.
