The average rate of change of the function between x = 15 to x = 25 is celsius per thousand feet and represents the rate of change of temperature per thousand feet.

60 2(x + 2) in the diagram, gef and hef are congruent. what is the value of x?

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

Simplify this expression. 8x 16(x + y)
