A rich singer has donated $450,846 to endow a university professorial chair in Bohemian Studies. If the money is invested at 12.65%, how much can be withdrawn each year, ad infinitum (indefinitely), to pay the Professor of B. S.

Annual withdrawal=  $57,032.02

Explanation:

Giving the following information:

Initial investment (PV)= $450,846

Interest rate (i)= 12.65%

To calculate the annual withdrawal, we need to use the following formula:

PV= Cf / i

Cf= annual cash flow

450,846= Cf / 0.1265

450,846*0.1265 = Cf

Cf= $57,032.02

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
