Let u be the set contains all the twelve months in the year, that is, u = {jan. , feb. , mar. , · · · , nov. , dec.}. given that a = {jan. , feb. , mar. , apr. , may} and b = {apr. , may , june , july , aug. , sep. , oct.}. find (a) a\b (b) b\a (c) a ∩ b (d) a ∪ b (e) ac ∩ bc (f) ac ∪ bc (g) (a ∩ b) c (h) (a ∪ b) c (i) is the statement “ (a ∪ b) c = ac ∪ bc ” true? verify it. (j) is the statement “ (a ∩ b) c = ac ∪ bc ” true? verify it.

Evaluate-27 ^4/3/8 a) - 81/16 b) 81/16 c) 16/81

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
