Glottochronology is the anthropological study of language change and evolution. One standard theory (Swadish 1950,1952 ) holds that words endure in a language according to a "decay rate" that can be expressed as \[ y=c^{2 t} \] where \( y \) is the proportion of words that are retained in a language, \( t \) is the time in 1000 years, and \( c=0.805 \) is a constant. a. Re-express the relation using "e" (i.e., 2.71 ...) , as is done in some settings, according to \( y=e^{-t / \tau} \), where \( \tau \) is a constant you must derive. b. Van der Merwe (1966) claims that the Romance-Germanic Slavic language split fits a curve with \( \tau=3.521 \). Graph this curve and the curve from \( \tau \) derived above with an \( x \)-axis along 0 to 7 . What does this show? anned with CamScanner
