Answer:
20 mins
Step-by-step explanation:
Well town A has an annual growth that stays constant. town B has a 10% growth which is exponential because it takes a percent of the whole number and adds it so if you have 145 residents in 2006 in say three years in 2009. in 2007 its population would be 159.5> rounded up because you can't have half a person it would be 160. in 2008 it would be 176 and finally in 2009 it would be 194. that's a growth of 49 in three years where as town a grows only ten people per year. which means town a would only grow by 30 people in three years and have a population of 175.
Answer:
There's a lot of them.
There are many different ways to calculate . The ones used by computers to generate tons of digits are usually infinite series.
The series that has been prominent in recent records for the most digits of pi is the Chudnovsky algorithm.
The algorithm is this:
For faster performance, it can be simplified to this:
Other algorithms have been used, but right now this is the one that is being used to set the recent records.
There are also some approximations that are used because they are very easy to calculate.
first, can be used to calculate a fairly accurate pi, but a better rational approximation is This fraction is actually accurate to 6 digits and it is the best approximation of in simplest form and with a denominator below 30,000.
There are several other approximations and if you want to learn more I would recommend looking at the Wikipedia page which has tons of algorithms for pi.
Answer:
The answer to your question is below
Step-by-step explanation:
a)
32.6 grams of H₂O to moles
molar mass of water = 2 + 16 = 18 g
18 g ------------------- 1 mol
32.6 g ---------------- x
x = (32.6 x 1)/18
x = 1.81 moles of H₂O
b) 22.7 grams to molecules
18 g of H₂O ----------------- 6.023 x 10²³ molecules
22.7 g of H₂O ------------- x
x = (22.7 x 6.023 x 10²³)/18
x = 7.59 x 10²³ molecules
The coordinates of label 6 would be in (0,-5).
