What axioms must be satisfied for a collection of subsets to be called a topology on a set?
There are three axioms that must be satisfied for a collection of subsets, t, of set B to be called a topology on B.1) Both B and the empty set, Ø, must be members of t.2) The intersection of any two members of t must also be a member of t.3) The union of any family of members of t must also be a member of t.If these axioms are met, the members of t are known as t-open or simply open, subsets of B.See related links.

Find Angle t if angle t is 20 more than four times its supplement?
Find the measure of the angle T, if the measure of the angle T is 20 more than four times its supplement. The supplement of T = (180-T) Write an equation for the statement: "angle T is 20 more than four times its supplement." T = 4(180-T) + 20 T = 720 - 4T + 20 T + 4T = 720 + 20 5t = 740 T = T = 148 degrees Check solution in original equation: 148 = 4(180-148) + 20 148 = 4(32) + 20 148 = 128 + 20
The equation of rotation geometric transformation?
In two dimensions, the equations of rotation about the origin are: x' = x cos t - y sin t y' = x sin t + y cos t. where t is the angle of rotation, counterclockwise.
