1. I am a whole number. When you multiply me by four, subtract eleven and take the
square root, you get the number of square feet in a square whose sides have length 36
inches. Showing each of your steps, find me.
2. Let U={n|nis an integer 1 ≤n≤10}be the universe for this problem. Define
S={n|nis a square number }and T={n|nis a power of 2 }. Find Tcand S∩(Tc),
expressing both using the method of enumeration of elements.
3. Draw a Venn diagram featuring three sets A,B, and Cwhere each pair of these sets
intersects in a nonempty set, yet the intersection of all three is empty. Shade in the region
that represents Ac∩(B∪C).
