c=?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

Err. Missing the 10^8

OpenStudy (anonymous):

Big difference there ;)

OpenStudy (angela210793):

lol yea :D

OpenStudy (anonymous):

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

OpenStudy (anonymous):

Wrong, speed of a light in a vacuum.

$4+\sqrt{16 - 4* -1* c} --------------------- =-5 2*-1 OpenStudy (anonymous): Not so much wrong as not completely right :) On to the actual problem. OpenStudy (anonymous): C=5. Give me a minute to show the work. OpenStudy (anonymous): alright! OpenStudy (anonymous): \[\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: $16+4c=36$ $4c=20$ $c=5$

OpenStudy (across):

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