Answer:
2,827.43
Step-by-step explanation:
When you write the equation of a circle in the form

Then the center of the circle has coordinates
and the radius is 
So, in your case, the center of the circle is 
Answer:
x=2
Step-by-step explanation:
Add all the sides to find the perimeter
x+4 + 4x+10(x-1) = 24
Distribute
x+4+4x +10x-10 = 24
Combine like terms
15x -6 = 24
Add 6 to each side
15x-6+6 = 24+6
15x = 30
Divide each side by 15
15x/15 = 30/15
x = 2

We have the equations of 3 functions and we want to find which one of them will decay the fastest to 4 grams.
This can be done by setting each expression equal to 4 and find which of them gives the smallest value of t.
For Amount A:
Likewise for Amount B:
Similarly for Amount C:
Thus Amount C will take the minimum time to decay to 4 grams.
