Question

c=?

Answer 1

Depends on the context. In physics it's speed of light.\[2.9979\frac{m}{s^2}\]

Answer 2

Err. Missing the 10^8

Answer 3

Big difference there ;)

Answer 4

lol yea :D

Answer 5

And that's m/s not m/s^2. I need coffee.

Answer 6

Wrong, speed of a light in a vacuum.

Answer 7

\[4+\sqrt{16 - 4* -1* c}
--------------------- =-5
2*-1

Answer 8

Not so much wrong as not completely right :) On to the actual problem.

Answer 9

C=5. Give me a minute to show the work.

Answer 10

alright!

Answer 11

\[\frac{4+\sqrt{16-4(-1)(c)}}{2(-1)}=-5\]
Times each side by -2:
\[4+\sqrt{16+4c}=10\]
\[\sqrt{16+4c}=6\]
Square both sides:
\[16+4c=36\]
\[4c=20\]
\[c=5\]

Answer 12

For a moment I thought we'd start up on a discussion about relativity and space-time fabric. :P
