An open steel can of volume 216 l
is filled to the top with gasoline at
13.5°c. when it warms to
36.0°c, how much gas spills
over? (don't forget, both the can
and the gasoline are expanding.)

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

Write two subtraction equations that are equivalent to 5 + 12 = 17.
