well 11*$6 = $66

so if she goes to 11 games she will 'break even'

She will need to go to 12 games to be in front  

Maybe this will help  

Yes it is a fabulous site.

this is the page that I use the most

I have spoken of many times.

It is how I know that it is now about 11:30am in your neck of the woods.

You are 17 hours behind me but I don't have to think to hard.  I can just look at the map and if I know the city someone lives in I know what time it is for them :))

Good morning from Sydney, 

Today our wonderful answerers were Quentin, ZamariahLovesYuh(ZLY), Heureka, Alan, BrittanyJ, CPhill, Rosala, Geno3141, RandomGuy11, Panda6702, Kitty<3, Hellokittygirl56, TayJay and GoldenLeaf.  Thanks all.

We need another mathematician to arbitrate.  :)))

Yes CPhill is probably right.  Neither of us is really sure.   Thanks Chris :))

I find these confusing but if something increases 100% then it doubles so I guess if it increases 200% it triples.

so

if it originally takes 15seconds and it becomes 3 times faster i suppose it will now take 5 seconds.

what do you reckon CPhill, soes this sound right to you?

compounding yearly it is

1(1.06)^10

$${{\mathtt{1.06}}}^{{\mathtt{10}}} = {\mathtt{1.790\: \!847\: \!696\: \!542\: \!853\: \!6}}$$

so $1 will grow to $1.79

that is a 79% increase in value  :))

The point (-1,2) lies on the terminal side of theta in standard position. What are the exact values of sin theta, sec theta, and theta

theta is the obtuse angle with the vertex at (0,0)

$$\\sin\theta = \frac{opp}{hyp}=\frac{2}{\sqrt5}=\frac{2\sqrt5}{5}\\\\
Sec\theta=\frac{hyp}{adj}=\frac{\sqrt5}{-1}=-\sqrt5\\\\
\theta=180-atan(2)$$

$${\mathtt{180}}{\mathtt{\,-\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left({\mathtt{2}}\right)} = {\mathtt{116.565\: \!051\: \!177\: \!078}}$$  

$$\theta\approx 116.6\;\;degrees$$

No, it is NOT zero !!      It is undefined
