What is the center and radius of the circle with the given equation x^2 + y^2 + 14x - 12y +69 = 0
ohaa [14]

Answer:

Center is (7,-6)

Our radius is 4

Step-by-step explanation:

Subtract 69 to both sides

Complete the square of the x terms and y terms.

{x}^{2}  + 14x

{y}^{2}  - 12y

(To complete the square divide the coefficient by 2 and square it).

(\frac{14}{2} ) {}^{2}  = 49

( \frac{ - 12}{2} ) {}^{2}  = 36

Add those terms to the full equation. Add 36 and 49 to the right side as well

{x}^{2}   + 14x  + 49 +  {y}^{2}  - 12y + 36 =  16

Simplify the x and y terms into a binomial.

(x + 7) {}^{2}  + (y  - 6) {}^{2}  = 16

Set the left side equal to zero separately to find the center and take the square root of the right side to find the radius.

x + 7 = 0

x =  - 7

y - 6 = 0

y = 6

16 =  {x}^{2}

4 = x

So our center is (-7,6)

Our radius is 4.

Sonja [21]

we know that

1 ft-------> is equal to 12 in


step 1

find the area of the walk

18 in wide--------> convert to ft

18/12=1.5 ft

area=1.5*32------> 48 ft²


step 2

find the cost at $2.10 a square foot

multiply 48 ft² by $2.10

48*2.1=$100.80


therefore


the answer is

$100.80
