27 Minutes, 3 For your solution, put the coefficient in your form into the designated blank. For example, if you have
an answer that says "3x - 1," then you would type 3 in the box for c because it is the coefficient of x,
and - 1 into the box for d because it the the constant.
(2x – 1) (3x2 + 2. – 4) = ar3 + bx² + cx+d
Blank 1: a
Blank 2: b
Blank 3: C
Blank 4: d

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
