Determine whether the conjecture is true or false. Give a counterexample for any false conjecture.

Given: points R, S, and T
Conjecture: R, S, and T are coplanar.
Question 3 options:

False; the points do not have to be in a straight line.

False; one point may not be between the other two.

False; the points to not have to form right angles.

True

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
