A circle has the equation x2+y2+16y−30x=0.
What is the equation of the circle in standard form, the coordinates of its center, and the length of its radius?

The equation of the circle is (x+15)2+(y−8)2=289; the center is at (−15,8), and the radius is 17 units.

The equation of the circle is (x−15)2+(y+8)2=289; the center is at (−15,8), and the radius is 289 units.

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.

Select the point that is a solution to the system of inequalities. y< =-x+3 y=x^(2)-3x

Will mark the brainliest.paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each?
