Lauren's therapist was using Cognitive Behavioural Therapy [CBT]. CBT refers to a short term, goal oriented psychotherapy treatment that uses practical approach for problem solving. The principal goal for using this technique is to change the behavior or the mentality that is responsible for the patient problem.
The best answer would be: traditional economy (specifically, it's definitely neither market economy nor command economy - in those economies the family does not necessarily play a role in the chose of roles).
An example of such strict economic roles is ancient India - and the roles are called castes.
The dimensions of the cylinder can be used to minimise cost of manufacture.
<h3>How to we find minimised cost?</h3>
Let's ignore the metal's thickness and assume that the material cost to manufacture is precisely proportionate to the surface area of a perfect cylinder.
A=2πr(r+h)
Given that V=1000=r2h and h=1000=r2, we can write
A=2πr(r+1000πr2)
A=2πr2+2000r−1
By setting the derivative to zero, we may determine the value of r that minimises A:
A′=4πr−2000r−2
0=4πr−2000r−2
2000r−2=4πr
2000=4πr3
r=500π−−−√3
r=5.419 + cm
h=1000πr2=10.838 + cm
The can with the smallest surface area has a volume of 1000 cm 3 and measures 5.419+ cm in radius and 10.838+ cm in height. The can has a surface area of 553.58 cm 2. Given a constant volume, the cylinder with diameter equal to height has the least surface area.
Can surface area (cm2) versus. radius (cm), where capacity = 1000cm 3.

Answer: 22; 7
Explanation;
A Recession refers to the economy of a country contracting for at least 2 quarters.
Since the the beginning of the twentieth century, the United States has experienced<u> 22 recessions </u>with the worst being the Great Depression of 1929 and the Great Recession of 2008.
Of those,<u> 7 have occurred since 1970</u> with the 7th ongoing as a result of the Corona virus pandemic.
