HALP MY FRIEND NEEDS HELP AND ITS DUE TM (ALSO 69 POINTS ;) PLS ANSWER QUICKLY For the positive integer n, let [n] denote the sum of all the positive divisors of n with the exception of n itself. For example, [4]=1+2=3 and [12]=1+2+3+4+6=16. What is [[[28]]]?

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
