The median weight of a boy whose age is between 0 and 36 months can be approximated by the function w(t) = 755 + 1.71t-0.0015t-+ 0.000597+ where t is measured in months and w is measured in pounds. Use this approximation to find the following for a boy with median weight in parts a) through c) below. a) The rate of change of weight with respect to time. w'(1) = b) The weight of the baby at age 7 months The approximate weight of the baby at age 7 months is|lbs. (Round to two decimal places as needed.) plic c) The rate of change of the baby's weight with respect to time at age 7 months. rody The rate of change for the baby's weight with respect to time at age 7 months is approximately |Ibs/month.
