Answer:
Um i know a good sight that will do this for you it picture homework
Step-by-step explanation:
Note the general equation of a circle is x^2 + y^2 = r^2, with centre (0, 0) and radius: r.
So, our equation of a circle is (x + 3)^2 + (y - 1)^2 = 100
Subtract 100 from both sides and plug in the points. If it equals to 0, then the points satisfy the equation of the circle (ie lies on the circle)
A 33 gram sample has k value of .1124
(Actually I think the problem SHOULD be worded: A 33 gram sample has k value of -.1124/days)
See attached graphic:
Half-Life = ln (.5) / k
Half-Life = -.693147 / -.1124/days
Half-Life =

Well one third is 100
so two thirds must be 200
I would change the fractions to decimals so that I could see least to greatest.
19/6=3.17
47/14=3.36
83/2=41.5
Least to greatest:
19/6, 47/14, 83/2
