Use demoivre’s theorem to write the complex number in trigonometric form. (cos(3pi/t)+isin (3pi/5))^3 your choices are: 3(cos(9pi/5)+isin (9pi/5)) (cos(3pi/15)+isin (3pi/15)) 3(cos(3pi/15)+isin (3pi/15)) (cos(9pi/5)+isin (9pi/5))

idk i would have to be there to under stand it

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
