3​, given in polar​ coordinates, and find other polar coordinates (r,θ) of the point for which the following are true.
​(a) r>0, −2π≤θ<0 ​(b) r<0, 0≤θ<2π ​(c) r>0, 2π≤θ<4π
Select the correct graph that represents the point 3,
5π
3 below.

The lengths of nails produced in a factory are normally distributed with a mean of 4.91 centimeters and a standard deviation of 0.05 centimeters. find the two lengths that separate the top 4% and the bottom 4%. these lengths could serve as limits used to identify which nails should be rejected. round your answer to the nearest hundredth, if necessary.
