Name the minor arc and find its measure. a. ab 162° b. adb 162° c. ab 198° d. adb 198°

A minor arc is an arc of a circle having measure less than or equal to 180° or π radians. From the options given above the arc which has a measure less than 180° is AB. 

Information: ADB 198° is the major arc as its central angle is greater than 180°.

The correct option is (A).

-i

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
