What is not an example of kinetic energy? Question 6 options:

Particles in motion, such as electricity

Elastic energy, such as a stretched archery bow.

Substances in motion, such as light, heat, and sound

Objects in motion

squares, rhombus, rectangles

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
