Gabriel cycles 1,200 meters in 6 minutes. What is his speed?

In simplified exponential notation, the expression a^2•a^-3•a 1/a 0

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

Factor the polynomial by its greatest common monomial factor.
