Use the formula r= log10 i where r is the measurement of the richter scale and i is the intensity, to find the richter scale measurement of an earthquake with intensity 65,000,000 ergs. a.17.99 b.6.81 c. 5.75 d. 7.81 20 pts,

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
