Jair · Answer 1

First we find k by using the two values given:

P=Ae^ (kt), 8 years between-->t=8

199 = 195•e^ (8k)

Log 199 = Log [195•e^ (8k) ]

Log 199 = Log 195 + 8k

8k = Log 199 - Log 195

k = 0.00882/8 =.0011

Next, we plug the new data in using this k:

14 years between 2002-2016-->t=14

P = Ae^my

P = 199mi.•e^ (14•.0011)

P = 199mi.•e^ (.0154)

P = 199mi. • 1.0155 = 202,088,000
