10 2/5 times 15 5/7 is 5,720/35 which is 163 15/32 in mixed number
Exponential growth/decay rule with general function is:<span>y=y(0)<span>e<span>kt</span></span></span>
with k is growth/decay constant rate.
(1) Deer population function
y(0) = 1253
k
= 3%
t
= 6 (years)
y(6) = 1253 . e^(0.03*6) ~ 1500 (deers)
: 1496 deers
(2) Growth factor b is rate 9.5% = 0.095
2x+3y=6
3y=6-2x
y=2-2/3x
y=-2/3x+2
the 3rd one is correct
