Luke has $20 in a savings account that earns 10% interest, compounded annually. To the nearest dollar, how much will he have in his account after 2 years?

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

Find the quotient with the restriction.
