Help When graphed, the circle with equation x2 + y2 - 14x + 10y + 65 = 0 will lie ENTIRELY in Quadrant A) I. B) II. C) III. D) IV. A beach has to enclose a rectangular area, because some endangered species are nesting there. They have 200 feet of rope to rope off the area with. What is the maximum area that they can rope off? A) 50 ft2 B) 100 ft2 C) 2500 ft2 D) 5000 ft2

\[x^2 + y^2 - 14x + 10y + 65 = 0 \] you have to complete the square twice or else cheat your choice

please pick one soon, i gotta run in ten minutes

I got It

OpenStudy (misty1212):

hi still need help or you got both?

OpenStudy (omgthatgirl):

Need help with the second one

OpenStudy (misty1212):

make a square

OpenStudy (misty1212):

since you have 200 feet each side will be one quarter of that, or 50 area will be \(50^2\)

OpenStudy (misty1212):

there are lots of ways to solve it using math, but really it is kind of obvious that the rectangle with fixed perimeter and largest area is the most symmetric one, a square
