You can post chem/physics problems. :))

However, it might be unanswered since some people haven't learnt it yet.

Thanks a lot @catmg!

We have 2 legs of the right triangle, 6. 

6*6/2 = 18. 

=^._.^=

.75x + 18

x = 24

=^._.^=

We  have  this  equation

y =  Asin (Bx)

A = the  amplitude =   5

B =  2pi / 4 =  pi / 2

a)   the equation is    y = 5*sin (pi x / 2)    where  y is  the displacement

b )   Here's  the  graph over the first 15  seconds :   https://www.desmos.com/calculator/tyfa6l1rn4

800000  =  A  ( 1.05)^10

800000 / (1.05)^10   =   A  ≈  $491130.60

There are 15 ways to arrange the keys.

The probability is 2/15.

it equals 53

i just finshed answering the question imao

you can also just put it in a calculator 

it is 7 1/5 because when we dive 36/5 we gate 7 as our integer, and there is only 1/5 left so 36/5 is equal to 7 1/5

what is = to infinity? infinity is not a real number, for example, 1+2+3+4+5+6+7+8+9+........ will be infinity or not we don't know, but what we know is this number is closer and closer to infinity, just like when 1/(very large number) = about 0 when 1/(more large number) = closer to 0 when 1/(the greatest number possible)= infinity, but there is not a number that is the greatest so infinity does not exist, but is dose not another way, we can get it when we don't do any mathematics calculation.  (sorry, my typing is very bad)

log0 is undefined :)

so how to ask it?

ya brainly is awsome 

ok? 

 line tangent to both circles is the line x = 3, as both circles intersect point (3,0)

Nevermind, probably not. I think asking brainly or something is a better optiono

I think you can post it as an off-topic quesiton

8:03 PM on a 24-hour clock is 20:03.  

maybe but i don't care

you can look at the question right after this, he/she ask the same question. :) but a quick explanation, it is basically the learning of angles and slides. the basic trigonometry only uses the right triangle, also you need to know a^2+b^2=c^2 and sin=opposite/hypotenuse  cos=adjacent/hypotenuse and tan=opposite/hypotenuse, I hope that help. :)

You don't even know what you're talking about stop bullshitting
