Let s be the subset of the set of ordered pairs of integers defined recursively by basis step is (0, 0)∈ s recursive step: if (a, b) ∈ s, then (a, b+1) ∈ s, (a+1, b+1) ∈ s, and (a+2, b+1) ∈ s what is the list of the elements of s produced by the first four applications of the recursive definition?

An energy plant is looking into putting in a system to remove harmful pollutants from its emissions going into earth's atmosphere. the cost of removing the pollutants can be modeled using the function c = 25000p/100 -p what is the vertical asymptote?

Amountain climber starts a climb at an elevation of 453 feet above sea level at his first rest stop he has climbed 162 feet and by his second rest stop he has climbed another 207 feet its getting late in the day so the climber starts his way down if the climber desends 285 feet how much does he need to ascend or descend to return to the original starting point

Which function can be used to model the monthly profit for x trinkets produced? f(x) = –4(x – 50)(x – 250) f(x) = (x – 50)(x – 250) f(x) = 28(x + 50)(x + 250) f(x) = (x + 50)(x + 250)
