A curve C in straight real numbers cubed is defined implicitly on the the cylinder x squared plus y squared equals 1 by the additional equation x squared minus x y plus y squared minus z squared equals 1. Find the distance of the point on C that is closest to open parentheses 0 comma 0 comma 0 close parentheses. Enter your answer in decimal form "a. bc".

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities
