Let a(t) be the area of tissue culture at time t (in days). let the final area of the tissue when the growth is complete be 10 cm2. most cell divisions occur on the periphery of the tissue and the number of cells on the periphery is proportional to a. so, a reasonable model for the growth of tissue is obtained by assuming that the rate of growth is jointly proportional to va and 10 a a) formulate the differential equation that models this situation

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
