Let X = {n ∈ N : 10 ≤ n < 20}. Find examples of sets with the properties below and very briefly explain why your examples work. (a) A set A ⊆N with |A| = 10 such that X \A = {10,12,14}.

(b) A set B ∈P(X) with |B| = 5.
(c) A set C ⊆P(X) with |C| = 5.
(d) A set D ⊆ X ×X with |D| = 5
(e) A set E ⊆ X such that |E|∈ E.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

answer: i think it is (1,-2)

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
