Math appendix! Hope I helped!!
There is actually a lot of wan technologies that are carried over the pstn. But the first thing we have to do, is to know what does the pstn means. The pstn means Public Switched Telephone Network. Though they have some similarities, the atm and the wan are different machines.
Given Information:
Current Population = P₀ = 7 billion = 7x10⁹
Growth rate = r = 3 %
Period = t = 100 years
Required Information:
(a) Population after 100 years = ?
(b) Population after t = 0, 1, 2, 10, 25, 50 years = ?
(c) Population vs time graph = ?
Explanation:
The human population growth can be modeled as an exponential growth,

where P₀ is the current population, r is the growth rate and t is the time period
(a) What would the population equal 100 years from now?

P = 140.6x10⁹
(b) Compute the level of the population for t = 0, t = 1, t = 2, t = 10, 25, and t =50
<u>t = 0</u>
P = 7x10⁹e⁰
P = 7x10⁹
<u>t = 1</u>
P = 7x10⁹e^0.03*1
P = 7.213x10⁹
<u>t = 2</u>
P = 7x10⁹e^0.03*2
P = 7.423x10⁹
<u>t = 10</u>
P = 7x10⁹e^0.03*10
P = 9.45x10⁹
<u>t = 25</u>
P = 7x10⁹e^0.03*25
P = 14.82x10⁹
<u>t = 50</u>
P = 7x10⁹e^0.03*50
P = 31.37x10⁹
(c) Make a population versus time graph

Answer:
b. explore their personal beliefs and perspectives about cofacilitation.
Explanation:
Looking at the above scenario, the right alternative for Dan and Rachel to be effective co-leader models for members of an anxiety disorder group would be to explore their personal beliefs and perspectives on cofacilitation.
A support group for anxiety disorders aims to share the beliefs, perspectives and personal experiences of each member of the group so that there is exchange and mutual support for problems, greater understanding and resolution of problems.
In this case, the leaders must be the facilitators of the group's objectives, that is, they must be the examples of how to engage the members of the group, include everyone in the exchange of experiences and motivate them to reach the solution of the problems.
The statement that accurately describe the innovations that they've made is :
