3^2 + 4^2 = 5^2

Step-by-step explanation:

This is used to help prove the Pythagorean theorem

The left side of the triangle is 3 units and the bottom of the triangle is 4 units.  The hypotenuse is  5 units

a^2 + b^2 = c^2

3^2 + 4^2 = 5^2

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
