Step-by-step explanation:
General equation of the circle with center (h,k) and radius r,
(x-h)²+(y-k)²=r²
Therefore, on comparison
center ( 4, -2)
radius r= 4√2
Answer: 1/7
Step-by-step explanation:
solve for y
6 then thousandths=60,000
1 more thousandth then 10,000=11,000
No hundreths=000
3 more tens then 10,000=40,000
And 4 fewer ones than 10,000=9,996
Add that all together and you get 121, 996

Since we have given that
Number of tagged silvery minnows = 54
Number of captured silvery minnows = 62
It includes 12 tagged silvery minnows.
So, Number of silvery minnows without tags = 62 -12 =50
So, Good estimate of the silvery minnow population in the Rio Grande River would be
