Well Chris, I want   3 points too  - from you      (plus one from BJ)

Mine is more intelligent drivel than yours is  !!!!!

BJ gave him one....and I gave him the other three......it was "intelligent" drivel.........

Hey Saseflower, you made a boo boo     

They are equal

Just remember, rosala......take your house key with you.....LOL!!!

I wonder who gave you 4 points for that drivel Nauseated. 

You must have a fan club I guess - there is no accounting for taste!   

See you later alligator   

Thanks Saseflower  

Thanks anon,

You are best to do it all at once and then you will get less rounding error.  :)

sin(24.6)/cos(62.1)

$${\frac{\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{24.6}}^\circ\right)}}{\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{cos}}{\left({\mathtt{62.1}}^\circ\right)}}} = {\mathtt{0.889\: \!622\: \!288\: \!584\: \!947}}$$

Mmm

you could buy any number N that satisfied this equation

N=9A+13B+20C         where A,B,and C  were all integers >=0     

I would have thought that there was no maximum amount that could not be bought but I really have NO idea how to do this.

Maybe another mathematician can show us how?

I tried to enter it in wolfram|Alpha but I do not know how to do the input.  

Hi Mellie,

Geno has answered this quesion now,

Thanks Geno :)

MathsGod1,

please refer them to the sticky topic "how do I type in fractions?"

The sticky topics are on the bottom right of your page.

Hi 315,

I know almost nothing about vectors so I am hoping to learn from your question too.

If two vectors are skew then that means that they are not coplanar.

It seems to me that if the vectors are parallel then they have to be coplanar.  

So, what are skew parallel vectors?

Basically if something is raised to a negative power then put it on the other side of the fraction line and change the negative to a positive.

If there is no fraction line to start with then draw one in and put 1 on the bottom :)

Here is a post that could help you more:

Thanks Geno - that is by far the easiest way :)

I would call the probability of not thowing any 4 in seven rolls and the probabiliy of throwing at least one 4 in seven rolls a conjugate pair because on or the other has to happen (there must be a word for this) and they cannot both happen.  (They are mutually exclusive).

I have just googled this to see if my terminology is correct but all I got was a heap of 'gobble'd'g**k'.

Can a mathematician please discuss the correct terminology here.   

Thanks guys :)

I really like that you have interacted with the answerers anon, I wish a lot more people did that.

Sometimes we feel like we are teaching thin air.   :))

Try putting your points into Desmos calculator. :)

I am not sure what 2 points means.

But if x(ferformance)  goes up by 2 then y (attitude)  will go up by  1.02*2 = 2.04   

Hi Alan,

I was just thinking about this.

If you put one of the balloons at the centre of a sphere with a radius of r units.  

Then for that sphere  the       $$Surface \;area=4\pi r^2$$

The attractive force will be the same for every point on the surface of that sphere.

Now

It is a concentic sphere encases the first one and it has a radius of  3r then

For this second sphere    

   $$\\Surface \;area=4\pi (3r)^2=4\pi*9r^2=9*(4\pi r^2) \\= 9*$ the original spheres surface area$\\\\$$

So the force would have to be 9 times less if the radius is 3 times more.  

Does that make sense Alan?

4*sqrt(7)

that is if you use the input bar

Hi Zacismyname,

Welcome to the forum.    :D

I think I may nickname you Zac   LOL 

OHHHH! Burn!!!!

sounds correct 2 me..LOL

LOL!!.....I don't even know WHAT the question was, exactly......just a guess....

Categorizing that question as a “Social Studies” question is dumber than Categorizing “Astronomy” as “Astrology.”

I know you are not intelligent trolls, because you would have called it “Geography.”

I hope neither of you are answering math questions on here. Your CDD is in full bloom and may be terminal. If I was that stupid, I would stay anonymous too.

BTW that is a “Geology” question. You two can call it Social Studies if you want –most will understand why, now.
