31. At the beginning of a study, a certain culture of bacteria has a population of 80. The population grows to where there are 216 bacteria after 13 days. How many bacteria are there 19 days after the beginning of the study? Use A = Age(+¹) where: A is the final amount at time t; A is the initial amount; r is the rate of growth or decay; It is the time in days; e is the natural log. Round your answer to the nearest whole number.

Answer:
في بداية دراسة ما، كان عدد نوع معين من
البكتيريا 80.
الاجابة:
يوم، تكاثرعددها بحيث وصل إلى
13
بعد
.216
كم يصبح عدد البكتيريا بعد مرور 19 يوماً
منذ بداية الدراسة؟
(A = Aer0t بحيث:
استخدم
العدد النهائي للبكتيريا عند الزمن t ،
A هي عدد البكتيريا عند بداية الدراسة،
هي
A
ا هو معدل التكاثر أو التحلل،
t هوالزمن بالأيام.
هو اللوغاريتم الطبيعي.
