Question 31 (1 point) The rate of growth of a tumour is given by r(t) = 3t? In(2)2 mg per month. If the initial size of the tumour is 2 mg when t = 0, and treatment starts when the tumour is 257mg, when will treatment start (in months)? a) 1 b ) 2 c) 3 d) 4 e) 5 f) None of (a) through (e) are correct Of Question 32 (1 point)Question 32 (1 point) A heart surgery patient is prepared for surgery. The body's metabolism is slowed (by drugs) so that it generates negligible warmth. The body is placed in a bath of water kept at a constant ambient temperature TA (C). The formula for the cooling of a body is given by T(t) = TA + (To - TA)e-kt where k = In(3) hours -1. If the initial temperature of the body is 37 .C, and the body is placed in the bath for one hour and cools to 33 .C, what is the ambient temperature of the bath? a) 31.C b) 32 C c) 28.C d) 29 C e) 34.C f) None of (a) through (e) are correct Of
