What is the product of 1.54 and 2.6?

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

You can find the constant of proportionality by finding the ratio of

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)
