A farmer has 120 bushels of apples to sell at her roadside stand. She sells an average of 14 1
4 bushels each day. Represent the total change in the number of bushels she has for sale after 7 days.

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
