Following Exercise 3.5.9, let p1, . . . , pk be a pairwise relatively prime set of naturals, each greater than 1. Let X be the set {0, 1, . . . , p1 −1}× . . . ×{0, 1, . . . , pk −1}. Define a function f from {0, 1, . . . , p1p2 . . . pk − 1} to X by the rule f(x) = x%p1, . . . , x%pk. Prove that f is a subject

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 33 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30 ∘c on monday, but decreased at a constant rate in the next 33 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.
