A geometric sequence is given by the recursive rule a1=2/3, an=3an−1. Give an explicit rule for the nth term of the sequence b1, b2, b3, … , given that b1=a1, b2=a3, b3=a5, ….

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)

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

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
