Answer:
C / (2 pi) = r
Step-by-step explanation:
C = 2 pi r
Divide each side by 2 pi
C / (2 pi) = 2 pi r/ (2 pi)
C / (2 pi) = r
Answer:
6 + 4x − x² = 10 − (x − 2)²
the turning point : (2 , 10)
Step-by-step explanation:
6 + 4x − x² = − x² + 4x + 6
= − (x² − 4x) + 6
= − (x² − 4x + 4 − 4) + 6
= − [(x − 2)² − 4] + 6
= − (x − 2)² + 4 + 6
= − (x − 2)² + 10
= 10 − (x − 2)²
Then the turning point of y is (2 , 10)
First we must apply the Quotient rule that states,
This means that our derivative becomes,
Now we need to calculate 
and 
From here the new equation looks like,
And that is the final result.
Hope this helps.

Answers are in bold:
-1=3x-2
add 2 to both sides
-1+2=3x-2+2
1=3x
divide both sides by 3
1÷3=3x÷3
1/3=x
-3x=9
divide both sides by -3
-3x÷-3=9÷-3
x=-3
-10=-5x
divide both sides by -5
-10÷-5=-5x÷-5
2=x
I hope this is good enough:
Multiply 15 x 3.14. You'll get 47.1. Thats the area
