Use what you know about negative exponents to choose the equation below that is equivalent.
a.) y = 25000(1.16)^x
b.) y = 25000 (1/1.16)^x
c.) y = 25000(1/16)^x

answer - B

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
