Assume that you are only allowed to use the 26 letters of the alphabet to construct passwords of length n. assume further that you are using the same password in 2 systems where one accepts case sensitive passwords but the other does not. give an upper bound at the number of attempts required to guess the case sensitive version of a password

What are two of the most common reasons that peolpe who need mental health care do not access it?

The “rule of 72” is used to approximate the time required for prices to double due to inflation. if the inflation rate is r%, then the rule of 72 estimates that prices will double in 72/r years. for instance, at an inflation rate of 6%, prices double in about 72/6 or 12 years. write a program to test the accuracy of this rule. for each interest rate from 1% to 20%, the program should display the rounded value of 72/r and the actual number of years required for prices to double at an r% inflation rate. (assume prices increase at the end of each year.)

Suppose a cpu with a write-through, write-allocate cache achieves a cpi of 2. what are the read and write bandwidths (measured by bytes per cycle) between ram and the cache? (assume each miss generates a request for one block.)
