Create a program to determine whether a user-specified altitude [meters] is in the troposphere, lower stratosphere, or upper stratosphere. the program should include a check to ensure that the user entered a positive value less than 50,000. if a nonpositive value or a value of 50,000 or greater is entered, the program should inform the user of the error and terminate. if a positive value less than 50,000 is entered, the program should calculate and report the resulting temperature in units of degrees celsius [∘c] and pressure in units of kilopascals [kpa]. use the following information where h is altitude in meters, t is temperature in ∘c, and p is pressure in kilopascals: troposphere: altitude h < 11,000 m t = 15.04−0.00649 h

Some of your friends have gotten into the burgeoning field of time-series data mining, in which one looks for patterns in sequences of events that occur over time. purchases at stock exchanges--what’s being bought-- are one source of data with a natural ordering in time. given a long sequence s of such events, your friends want an efficient way to detect certain "patterns" in them--for example, they may want to know if the four events buy yahoo, buy ebay, buy yahoo, buy oracle occur in this sequence s, in order but not necessarily consecutively. they begin with a collection of possible events (e.g., the possible’ transactions) and a sequence s of n of these events. a given event may occur multiple times in s (e.g., yahoo stock may be bought many times in a single sequence s). we will say that a sequence s’ is a subsequence of s if there is a way to delete certain of the events from s so that the remaining events, in order, are equal to the sequence s’. so, for example, the sequence of four events above is a subsequence of the sequence buy amazon, buy yahoo, buy ebay, buy yahoo, buy yahoo, buy oracle their goal is to be able to dream up short sequences and quickly detect whether they are subsequences of s. so this is the problem they pose to you: give an algorithm that takes two sequences of even~s--s’ of length m and s of length n, each possibly containing an event more than once--and decides in time o(m n) whether s’ is a subsequence of s

Freya realizes she does not have enough in her bank account to use the debit card. she decides to use a credit card instead. which questions should freya answer before using a credit card? check all that apply. can i pay at least the minimum payment each month? can i make payments on time and avoid late fees? will i have to take out a loan? how much in finance charges can i afford to pay? should i talk to a consumer credit counseling service?
