A. If AB = 8 ft, find A"B".

A"B" = 8 ft

Step-by-step explanation:

From the given question, ABCDE has undergone transformation to produce images A'B'C'D'E' and A"B"C"D"E". But its size and shape has been preserved.

ABCDE was initially reflected and rotated with respect to point E to have A'B'C'D'E', which was finally reflected across line p to produce A"B"C"D"E". This implies that the dimensions of ABCDE were not affected in the process.

So that, AB = A"B" = 8 ft.

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
