What is the equation of this circle in standard form? (x+1)2+(y+2)2=49 (x−1)2+(y−2)2=7 (x−1)2+(y−2)2=49 (x+1)2+(y+2)2=7 A circle on a coordinate plane centered at begin ordered pair negative 1 comma negative 2 end ordered pair. The horizontal x-axis ranges from negative 10 to 10 increments of 1. The vertical y-axis ranges from negative 10 to 10 in increments of 1. The circle passes through begin ordered pair negative 6 comma negative 2 end ordered pair, begin ordered pair negative 1 comma 5 end ordered pair, begin ordered pair 6 comma negative 2 end ordered pair, and begin ordered pair negative 1 comma negative 9 end ordered pair.

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
