For positive acute angles AA and B, B, it is known that \cos A=\frac{45}{53}cosA= 53 45 ​ and \sin B=\frac{35}{37}.SinB= 37 35 ​ . Find the value of \cos(A-B)cos(A−B) in simplest form.

answer: i'm going in

step-by-step explanation:

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
