Answer
Find out the which coordinate pair identifies the center of the circle represented by 4x² + 4y² − 16x − 24y + 36 = 0.
To prove
The general equation of the circle is
(x - h)² + (y - k)² = r²
Where h,k are the centre and r is the radius.
4x² + 4y² − 16x − 24y + 36 = 0
Divided both side by 4.
x² + y² − 4x − 6y + 9= 0
Add and subtract 4 and 9
x² + y² − 4x − 6y + 4 -4 +9 - 9 +9= 0
x² + y² − 4x − 6y + 4 -4 + 9 - 9 +9= 0
x² + 4 - 2× 2 × x + y² + 9 - 2 × 3 × y = 9 + 4 - 9
using the formula ( a + b )² = a² + b² +2ab
(x - 2)² + (y - 3)² = 2²
Compare this with the general equation of circle.
Thus
h = 2 , k = 3
Option A is correct .
Answer: 27/34
Step-by-step explanation:
7 + 12 + 6 + 9 = 34
Minus 7 (red)
= 27
Answer
1. i believe the answer you are looking for is quotient which is the answer to a division problem
2. A divisor is a number that divides another number either completely or with a remainder. A divisor is represented in a division equation as: Dividend ÷ Divisor = Quotient. Similarly, if we divide 20 by 5, we get 4.
3. the result the quotient of the question
hope this helps and have a wonderful day :)
