The age/weight relationship of female arctic foxes caught in Svalbard, Norway, can be estimated by the function(adsbygoogle = window.adsbygoogle || []).push({});

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?
