This is easy, but I'm not a smart person, so here are my notes. Formulas:
Ohm's law: I=voltage/resistance
series circuit: Rtotal= R+R+R+.
Parallel circuit: 1/Rtotal= 1/R+ 1/R+ 1/R+...

[10 points, algebra 2-simplifying complex fractions]according to my answer key the restrictions are -1 and 4. but why not positive 1?

What is x and y intercepts for y=x+7

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
