The distance of an object thrown upward is modeled by the equation h=-16t+8t+1.25, where h is the height of the object in feet at any given time and t is the time in seconds. The object is visible whenever it is at h ≥ 0. For how long is the object visible? A. about 0.13 seconds B. about 0.50 seconds C. about 0.63 seconds D. about 1.25 seconds

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
