Determine the radius and center of the circle with the following equation <br> x^2+y^2-12x+24y-10=6

PolarNik [594]

Answer:

Center: (6, -12)

Radius: 4

Step-by-step explanation:

<u>Complete the squares</u>

<u /> $x^2+y^2-12x+24y-10=6\\\\x^2-12x-10+y^2+24y=6\\\\x^2-12x-10+46+y^2+24y+144=6+46+144\\\\(x^2-12x+36)+(y^2+24y+144)=196\\\\(x-6)^2+(y+12)^2=196$

Comparing with the standard form equation $(x-h)^2+(y-k)^2=r^2$ , since $r^2=196$ , then the radius of the circle is $r=14$ . Also, the center of the circle would be $(h,k)\rightarrow(6,-12)$ .

A regular workweek is 40 hours. Overtime pay is time and one-half): Manual is a word-processor operator. He makes $13.50 an hour

pychu [463]

Overtime is over 40 so subtract 40 from 54 and get
54-40=14
14 hours hovertime
so multipliy usuall pay by 40 (since worked 40 normal hours) then add to overtime pay by 14 hours so

(13.5 times 40)+(13.5 times 1.5 times 14)=
540+283.5=823.5
answer is $823.50
