The hands should be 3 and 9  that it 180 degrees apart

they are on 2 and 10 that is 120 degrees apart

The DECREASE is  60 degrees

Thanks Chris,

I'll give it a go too :)

Say you want to simplify the fraction    \(\frac{10}{15}\)

what you need to look for is common factors for the top and bottom, the common factor here is 5

\(\frac{10}{15}=\frac{5*2}{5*3}\)

I can cancel out the common factor and I will be left with     \(\frac{2}{3}\)

----------------------------

It works exactly the same there are letters involved.

\(\frac{9(x+y)}{9}=\frac{{9}*(x+y)}{9*1}=\frac{(x+y)}{1}=x+y\)

\(\frac{3t+6t^2}{3t}=\frac{3t*(1+2t)}{3t*1}=\frac{1+2t}{1}=1+2t\)

Good, it pleases me to hear that. 

Have you done calculus yet?

Nice try guest answerer but you have not taken into account that the population reduces each year, so the actual decrease in numbers is not going to be exactly the same every year.  It will steadily get less.  So your answer will be too low.

459 * (1-0.035)^15

= 459 * 0.965^15

= 269 bears

Some of my LaTex, (therefore some of my answer) has disappeared     

Hi Kitt,

What you have described in words is a combination

For example, 3 people are chosen from 10.  How many COMBINATIONS are possible   10C3=120   would be the answer?

For permutations, order matters.

For example.  10 people run in a race, how many PERMUTATIONS are possible for 1st, 2nd and 3rd places.

This is the same as:  choose 3 from 10 when order matters.     10P3=720 ways.

ok, that is a bit weird but at least I understand what you did now.  Thanks :)

The link doesn't work, you need to be able to sign in.

They probably do not want you to get outside help anyway.

I got 32 as well but I do not understand your logic.

I just said that for the g function

\(-8\le\frac{x}{2}\le8\\ so\\ -16\le x\le16\\\)

width =32
