The age/weight relationship of female arctic foxes caught in Svalbard, Norway, can be estimated by the function
M(t)=3102e^(-e)^(-0.022(t-56))
where t is the age of the fox in days and M(t) is the weight of fox in grams.
a) estimate the weight of a female fox that is 200 days old
i found that M(200)=2974.15g
b) Use M(t) to estimate the largest size that a female fox an attain (Hint: find lim as t->infinity M(t))
i found that it is 3102 grams
c)estimate the age of a female fox when it has reached 80% of its maximum weight.
is it
2481.6=3102e^(-e)^(-0.022(t-56))
0.8=e^(-e)^(-0.022(t-56))
then how do u solve for t?
d)estimate the rate of change in weight of an Arctic fox that is 200 days old.
how would u start this question?
