By Simon's Favorite Factoring Trick, the answer is -56.

The line is 7x - 2y = -1, so A + B + C = 7 + (-2) +(-1) = 4.

SP = PQ = 2        ST = 1        ∠SPT = ∠TPU 

tan(∠SPT) = ST / SP = 26.56505118°

∠SPT + ∠TPU =  ∠SPU = 53.13010235°

∠UPQ = 90° - ∠SPU = 36.86989765°

UQ = tan(UPQ) * PQ = 1.5

UR = RQ - UQ = 0.5  

Just considering REAL numbers for the domain of the fxn.

so   -8   and  -2   would be excluded    from all 'x'

Sorry, I don't know how to reduce it, but:

[24^50  -  15^50] mod 13 = 0

girlz jst cuz

AE = 70

just a bunch of similar triangles :)

You need to add brackets. I have no idea what your question is.

Oh

Is it       

integral of e^(1/x) / (x^2) dx    ? 

\(\begin{align*} \sqrt{3} \times 3^{\frac{1}{2}} + 12 \div 3 \times 2 - 4^{\frac{3}{2}} &= \sqrt{3} \times \sqrt{3} + 8 - (\sqrt{2})^3 \\ &= 3 + 8 - 8 \\ &= \boxed{3} \end{align*}\)

It would depend on what their made of and the size (mass) of each, of course.  If we assume similar dimensions and composition, then it would be the one that contains the least material.  That would be the ring, unless the ring is thick and the disk is real real thin like paper, then it would probably be the disk.

Yup! its good now!

Hi Hugo,

Do not worry this time but in the future, if you can find it easily, please add the address of the alternate post. (In a link)

This is more for the benefit of other users than it is for the asker of the question.

Thanks.

how about now?

I can't see the image?

The square root of 64 – 6²   

6² is 36 

64 – 36 is 28 

square root of 28 is 2•sqrt(7)

Four numbers are written in a row.  The average of the first two numbers is 1.  The average of the middle two numbers is 2.  The average of the last two numbers is 3.  What is the average of the first and last numbers? 

I don't have a formula, but just thinking about it, I see that

0, 2, 2, 4 will work.  So the average of 1^st and 4^th is 2.  

1, 1, 3, 3 will work too, the average of 1^st and 4^th is 2. 

There are other arrangements, as well, for example 2, 0, 4, 2 

I'm going out on a limb here and say that the average of the 1^st and 4^th numbers will always be 2. 

I haven't bothered to check out any negative numbers.  I'm tired of this problem.
