What is the best book to study introductory level topology?

1 answer:

5 0

I'm not sure if there's such a thing as "the" best (general, I'm assuming) topology textbook. I learned the basics from the first (general) half of Munkres, which I liked. I found that later, when I took abstract real analysis, I really liked the concise but still relatively comprehensive treatment in Folland's text on real analysis (Chapter 4). Of course it's not Bourbaki's General Topology or anything, in terms of coverage, but I still really like it. Incidentally, I also like Bourbaki's General Topology (at least the first volume, which I'm more familiar with).

7.RP.A.1 3. If 1 1/2 cups of something fills 2/3 of a container, how many cups fill the container?

Andreas93 [3]

Answer:

Hi there!

Your answer is:

2 & 1/4 OR 2.25 cups fills the container!

Step-by-step explanation:

If 1 & 1/2 (aka 3/2) fills 2/3 of the container, then:

we know that half of 3/2s fills 1/3 of the container

To find half of 3/2, we multiply 3/2 by the inverse of 2, which is 1/2.

3/2÷2

3/2×1/2 = 3/4 ths

Now that we know 3/4ths fills 1/3 of the container, we add that to 1& 1/2.

3/4+ 1&1/2 = 2 & 1/4

Check your work!

3/4 × 3 should equal 2&1/4 if we are correct

3/4 × 3/1 = 9/4.

Simplify!

9/4 = 2&1/4

That tells us that we are correct!

Hope this helps!

It is centered at (h,k) --> (0,0) and has a radius 9

The equation of the circle is

$(x-h)^{2} +(y-k)^{2} =r^{2} \\(x-0)^{2} +(y-0)^{2} =r^{2}\\x^{2} +y^{2} = 9^{2}$

Hope that helps!
