original Question
Have you ever looked at the sky and focused out at nothing,and have seen those things swimming in your eyes?
when i look at the sky, or just past a light,not looking into it,cause it hurts your eyes. i see little swimming objects,like unto, bacteria in eyes swimming,not to be sick,kinda like sperm cells under a microscope. just an example, don't be sick or will be reported!
just want to know if anyone else noticed this in you eyes,or maybe try to sit back and look just PAST the light, focuse out till you see them swimming, it might be blood in the vessels of the eyes, I DON'T KNOW, THAT'S WHY I'M ASKING,


not floaters ,but like blood cells

I am taking biology, physics, and chemistry this year all AP. I think biology is the easiest followed by chemistry, then physics. In general do people have a hard time with physics or chemistry?

which in turn would probably make it more easier to learn and even think about? Also would like one's input on the matter

In other words, what is the cardinality of the set of all permutations of the natural numbers?

Clearly, aleph_0 < aleph_0! <= aleph_0^aleph_0 = 2^aleph_0 = c,
but can it be proven that aleph_0! = c?

Are there any good sites that can help me with this or books that will make it easier. I must get to math 111 or I will not get the degree I want. Any help would be appreciated.

The square root of x+1 plus the square root of 3x equals the square root of 9x-2.

I know you square both sides...but then I got x+1+3x = 9x-2 and it wasn't correct. If anyone can just help me fix that part, that would be great and I can go from there.

O.K. I got htis part right... But I can't get it when I do the substitutes.... it confuses me... Can someone explain haw you go about it.

v=3k+5d solve for d
This is what I have

3K=5d=v
3k+5d-3k=v-3k
5d=v-3k
5d/5=v-3k/5
d= v-3k/5



Then I have to substitute.... Now i panic!!

Calculate the value of v when D = 20m , a = 9.8 m/s2, t = 20s

here it is:

The Petpet Supplies shop is 655 meters from the Smoothie Store, 393 Meters from the Defence Magic shop, and 314 meters from the Grooming Parlor. The Defence Magic shop is 236 meters from the Grooming Parlor and 524 meters from the Smoothie Store.

Assuming the distance between the Grooming Parlor and the Smoothie Store is less than the distance between the Petpet Supplies shop and the Smoothie Store, what is the distance between the Grooming Parlor and the Smoothie Store? Please round to the nearest meter.

Could you maybe help me with it? Im not trying to be lazy, i tried but i dont get it, plz help.

Whenever I see an animal show, I understand the animal is fed a treat as a reward for performing some trick (whether it be jumping through a hoop, walking on hind legs, or some other unnatural activity), but how to teach the animal that when you make such-a-such motion with your hand/arms they should perform that activity? Do they watch a human then mimic? Watch an already-trained animal then mimic? Physically taken through the motion in gentle baby steps, or via some other method? Is there an established criteria that animal rights groups have approved?

I suppose I have to solve this: I don't know where to start

v=3k+5d solve for d
This is what I have

3K=5d=v
3k+5d-3k=v-3k
5d=v-3k
5d/5=v-3k/5
d= v-3k/5

Is this correct?
