SOLVED:The number of years, N(r), since two independently evolving languages split off from a common ancestral language is approximated by N(r)=-5000 \ln r where r is the percent of words (in decimal form) from the ancestral language common to both languages now. Find the number of years (to the nearest hundred years) since the split for each percent of common words. (a) 85 \% \text { (or } 0.85) (b) 35 \% \text { (or } 0.35) (c) 10 \% \text { (or } 0.10)
