Let x = {a, b,c, d,e) and t = {0,{,,c,,c, d,e),x) (a). show that t is a topology on x. (b). what are the closed sets in t (c). what are the closures and interiors of (a), (b} as well as their boundaries. (d). give the closure of fa, bj. what can be deduced from that? (e). give the neighborhoods of c and d. (f). is t hausdorff.

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
