In urgent need for feedback on my speech for Transitions in society in relation to two related texts! Any help would be greatly appreciated :)
Should be less than 4 minutes
Question:
The process of transition may lead to growth and a range of consequences on individuals and society...
Sorry it wont upload
that is the whole first bit of the question, it then asks
a) Show that P(t)=P(t(subscript 0))e^-kt is a solution of the differential equation dP(t)/dt = -KP(t)
and
b) What percentage decline will there be after 10 years, given a 10% decline in 4 years? (answer = 23%)
and...
The population of a city is P(t) at any one time. The rate of decline in population is proportional to the population P(t), that is, dP(t)/dt = -KP(t).
What will the percentage rate of decline in population be after 10 years?
