Answer:
6.25 gm left
Step-by-step explanation:
Find the number of half lives in 26.3 years
26.3 / 5.26 = 5 half lives
(1/2) ^5 = 1/32 nd of the original will be left
1/32 * 200g = 6.25 gm left
The lenght of each diagonals is 1.
7,9,10 in that order in the y portion on the chart are the answers then use the x and y answers as graphing points for example the first one your going to graph is (3,7)
Answer:
The center of circle is
Step-by-step explanation:
We need to find the center of the circle of the equation ![x^{2}+y^{2}=4](https://tex.z-dn.net/?f=x%5E%7B2%7D%2By%5E%7B2%7D%3D4)
Since, the general equation of circle is ![(x-h)^{2}+(y-k)^{2} = r^{2}](https://tex.z-dn.net/?f=%28x-h%29%5E%7B2%7D%2B%28y-k%29%5E%7B2%7D%20%3D%20r%5E%7B2%7D)
Where (h,k) is center of circle and r is radius.
Re-write the circle equation is
as,
![x^{2}+y^{2}=2^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%2By%5E%7B2%7D%3D2%5E%7B2%7D)
Compare
with ![(x-h)^{2}+(y-k)^{2} = r^{2}](https://tex.z-dn.net/?f=%28x-h%29%5E%7B2%7D%2B%28y-k%29%5E%7B2%7D%20%3D%20r%5E%7B2%7D)
so, ![(x-0)^{2}+(y-0)^{2} = 2^{2}](https://tex.z-dn.net/?f=%28x-0%29%5E%7B2%7D%2B%28y-0%29%5E%7B2%7D%20%3D%202%5E%7B2%7D)
Hence, the center of circle is ![(0,0)](https://tex.z-dn.net/?f=%280%2C0%29)
