find the volume of the composite figure. round to the nearest tenth (use 3.14 instead of π ) explain

Match each inequality to the number line that represents its solution

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

Ineed to know the ordered pairs for this equation i need the answer quick because it’s a timed test
