The age/weight relationship of a particular animal can be estimated by the function M(t) =3120e - 0.02(t-53) , where t is the age of this animal in days and M(t) is the weight of this animal in grams. a. Estimate the weight of an animal that is 200 days old. The animal weighs approximately |grams when it is 200 days old (Round to two decimal places as needed.) b. Use M(t) to estimate the largest size that this animal can attain. (Hint: Find lim M(t)) The largest size that this animal can attain is approximately| grams (Round to two decimal places as needed.) c. Estimate the age of this animal when it has reached 80% of its maximum weight. The animal is approximately ||days old when it has reached 80% of its maximum weight. (Round to the nearest integer as needed ) . d. Estimate the rate of change in weight of an animal that is 200 days old. (Hint: Recall that D. e")] =f'(were) The weight of an animal that is 200 days old is changing at a rate of approximately ||grams a day (Round to two decimal places as needed.)
