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.

Mr.Foote placed a cement walk along the side of his house. The walk if 18 inches wide and 32 feet long. What was the cost of the

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
