E=mc squared

what number is missing 1,3,__9__,27,81

a). f(g(x)) = 1/(x^2 + 5x)

b) This graph should help you to answer this:

3.1415.....etc. The circuference of a circle to it's diameter. Also, a delicious treat.

1.2193263e+37

if the number your percenting is over 1000, every 100 is 10%, so 1 is now .1

\(\sqrt[3]{2^2}\)       or   \(\sqrt[3]{4}\)

6.023 x 10^23  atoms/mole   x  .850 mole  =====

Yes.

About 87.6

But thats if you ride a giraffe first

That is the equation used to describe a straight LINE on the coordinate plane.

4184 j/(kg k)  x  5 k  1kg  = 20920 j   ( the k and the kg 'cancel' ...leaving only 'j' )

That makes sense, thank you!

Am I correct by saying that there is no general solution for all values for y, but only two separate solution sets: one for y=0, and one for y=/=0?

sqrt(pi) ~= 1.77245385090551602729.

:)

Your first equation is incorrect....   you have   3 = 0

You can set it up as a RATIO:

21/100 = 48.3/x    CROSS multiply

21x = 4830            Divide by 21

x= 230  

Think about taking a small step, deltax, away from zero. If y(0) = 1 then dy/dx is non zero at x=0 and will start to change the value of y.  However, if y(0) = 0, then day/dx is zero and hence is unable to give rise to a change in y, so at deltax the value of y is still zero. Repeating this for another step of deltax therefore still doesn't lead to a change in y.  y stays at zero for all x.
