Solve problems using a calculator.To determine the thickness of a sheet of metal, six batches of 8 sheets each are measured with a digital micrometer. The thickness of each of the six batches of 8 is 0.3932, 0.3929, 0.3922, 0.3925, 0.3930, and 0.3924 mm. Find the average thickness of a single sheet of metal.

Solve the problem.A lens can be used to create an image of an object on the opposite side of the lens, such as the image created on a movie screen. Every lens has a measurement called its focal length, f. The distance s1 of the object to the lens is related to the distance s2 of the lens to the image by the function s1 = 
.For a lens with f = 0.3 m, what are the asymptotes of this function?
