This question refers to unions and intersections of relations. Since relations are subsets of Cartesian products, their unions and intersections can be calculated as for any subsets. Given two relations R and S from a set A to a set B, R βͺ S = {(x, y) β A β B | (x, y) β R or (x, y) β S} R β© S = {(x, y) β A β B | (x, y) β R and (x, y) β S}. Let A = {β2, 2, 3, 9} and B = {2, 3}, and define relations R and S from A to B as follows. For every (x, y) β A β B, x R y β |x| = |y| and x S y β x β y is even. Which ordered pairs are in A β B, R, S, R βͺ S, and R β© S? (Use set-roster notation to enter your answers.) A β B = R = S = R βͺ S = R β© S =

Atype of plant is introduced into an ecosystem and quickly begins to take over. a scientist counts the number of plants after mmonths and develops the equation p(m)= 19.3(1.089)^m to model the situation. most recently, the scientist counted 138 plants.assuming there are no limiting factors to the growth of the plants, about how many months have passed since the plants werefirst introduced? a)o 6.1b)0.6.6c)10 72d)o 23.1
