I have a Canon Rebel T3 and I am looking to get a case or bag for it. I would like something that I could take hiking and wouldn't be terribly bulky. But I also want something that isn't going to fall a part in a month. I don't really want to be spending over $60 dollars for it either. Any suggestions?

I need a little help proving the closure of an open set is the closed set.

Thanks :)

Suppose f:[0,1]->R with f(x)=1 for x is an element of C and f(x)=0 for x is an element of [0,1]-C, where C is the cantor set. Prove f is continuous for [0,1]-C. Any help would be great, thanks :)

Prove [0,1]-C is an open set, where C is the cantor set.

I am a little stuck, any help would be great thanks :)

So the full question states:

Prove that, if f is differentiable on (a,b), and f ' is bounded on (a,b), then f is uniformly continuous on (a,b).

Help on the whole proof would be awesome but I could use some help figuring out what f ' being bounded implies. Thank you.

I need an example of a sequence that is divergent but all of whose convergent subsequences converge to same number.

would this be like a sin or cosine function?

I'm looking for any ideas for a math club tee shirt. Our mascot is the lumberjacks. It can be anything but I'm really wanting something kind of funny or witty. Any ideas?

Use inductions to prove that (1+x)^n >=1+nx for -1<x and n=1, 2, 3...

any help would be greatly appreciated. thank you :)

show that:

||x|-|y|| <= |x-y| using the theorem that states that |x+y|<=|x|+|y|

Any help would be greatly appreciated. Thank you.

I was hoping for a proof that the complement of the intersections equals the union of the complements.

any help would be great. thank you!

So when i send a text it shows a bright red exclamation mark next to my sent messages. Im just curious what this means since the phone didnt really come with a manual.

okay so my equation is:

(dx/dt)+5/100(x)=1250-5t x(0)=10

If you could help that would great, or at least point me in the right direction.

hello,

i was hoping i could get a little help solving this problem:

(dx/dt)+(5/100)(x)=10sin(t) x(0)=10

any help would be great, thank you!

okay so i am attempting to make a program in dev C++. The prompt for the program is that it takes a list of numbers from a given file and outputs the median of the numbers. I understand that the numbers need to be put into an array then organized greatest to least. I just can't figure out how to get the numbers from the file into the program. Any help would be greatly appreciated. thank you!

Okay so this is a little hard to word, but I'm stuck and could use a little help.

the random variable is

(X_i) is X sub i

m is mu

(S^2)= (the sum from i=1 to infinity) of (((X_i)-(m))^2)/(n-1)

show that E[S^2]=s^2

s is little sigma.

any help would be great thanks.

I am aware that there are a lot of questions like this already on here, but I am tired of looking through them. The name is Jennifer, tall, skinny and blonde and I am looking for a stage name for a Burlesque group I'm am a part of. I'm more of a tom boy and I was thinking maybe more of a western sounding name. I go by Jennifer, Jenny and Jen. I'm not sure whether to use my real name or not. Any thoughts?

Air containing 0.06% carbon dioxide is pumped into a room whose volume is 8000 ft^3. The air is pumped in at a rate of 2000 ft^3/min, and the circulated air is then pumped out at the same rate. If there is a initial concentration of 0.2% carbon dioxide in the room, determine the subsequent amount in the room at time t. What is the concentration of carbon dioxide at 10 minutes? What is the steady-state, or equilibrium, concentration of carbon dioxide?

I need any help you can give me on answering this problem. Thank you.
