1. finish 6.14 ws - solution to the first problem posted below.
explanation for the exponents in number 1... it says "find a particular equation... of years that have elapsed past 1970." so, this means that in 1970, zero years have elapsed... so 1970 is "year zero." if you made the exponent 1970 instead of zero you would not be wrong... but your "a" value would be very small because you'd be finding the population in actual year zero (like biblical times). if 1970 is "year zero", then 1980 (ten years later) is "year 10."we could make year zero anything... if you did the same problem but made 1900 year zero, you would still get the same "b" value, but a different "a" value. make sense?
anyway... here is the solution.
2. QUIZ NEXT FRIDAY!! 6.2 - 6.6 and 6.14
