W+2x+2y+z= -2
W + 3x - 2y - Z=-6
-2w-x + 3y + 3z = 6
w+4x + y2z=-14

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6

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
