determine which of the following sets are equivalent to the set (x,y,z) a. (w,x,y,z) b. (1,5,17) c. (w,x,z) d. (a,b,a) e. (square, triangle, circle)

Given that v=[0,2] and w = [5,-8], what is w-v? a. 5,6 b.-5,6 c.5,-6 d.-5,-6

Let X={a,b,c,d}   Let T1={X, emptyset, {a}, {a,c}, {b}, {b,c}, {a,b},{a,b,c}, {b,c,d}} T2={X, emptyset, {b}, {b,d}, {c}, {c,d\}, {b,c},{b,c,d}, {a,b,c}}   how that the T1 and T2 topologies are topologically equivalent (you can give the homeomorphism or show that they are by their bases)

Determine whether each triple (a, b, c) is a Pythagorean triple. a) (3, 4, 5) b) (4, 5, 6) c) (5, 12, 13) d) (6, 13, 15)
