For quiz 4
A death body was found within a closed room of a house in Amityville NY where the temperature was a constant 70•F. At the time discovery, the core temperature of the body was determined to be 86•F. One hour later a second measurement showed that the core temperature of the body was 80•F assume the time of death corresponds to t=0 and that the core temperature at that time was 98.6•F.
A equation has to be derived from the above statement. And solve the following
a) determine how many hours elapsed before the body was found?
b) As is the case in these unprecedented times, evidence indicated the dead person was positive for COVID -19 and was running a fever of 102•F at the time of death. Repeat the determination steps for this case. Using same derived equation.

 

Sample Solution

prompting them to reduce their holdings of real money balances (Niskanen Center 2018).

It’s apparent that the Venezuelan government spending is significantly exceeding that which it is taking in and therefore putting them in a budget deficit. The government ceased releasing statistics with regards to the magnitude of the country’s budget deficit a few years ago. Nevertheless, reducing it is deemed a prime concern. However the CIA have estimated that the deficit is approximately 46% of the countries gross domestic product during the period of 2017 (Bloomberg 2019). One approach in hope of restoring Venezuela’s previously satisfactory economy, is for them to loan a significantly large amount of money – $60 billion over the period of three years – to them. Theoretically, this would enable the central bank to terminate the printing of Bolívar’s. This would, in theory, diminish the on going decrease of the Bolívar’s value – which has lost 99% of its value since 2013 (Bloomberg 2019). Similarly, replacing the national currency all together with a more stable currency – such as the US dollar – would be of benefit.

Another commonly identified flaw that Venezuela is victim of, is their reliance upon a single and arguably unstable, commodity – being crude oil. As previously mentioned, the country would benefit immensely from expanding their number and range of export goods. Over the past decade, the difficulties associated with oil extraction and production have seemingly become more apparent. Not only this but the imposition of several sanctions on Venezuela’s oil industry, on behalf of the US, are significantly contributing to the industry’s downfall. The sanctions have meant that the US – one of Venezuela’s key oil associates – are blocked from doing business with Venezuela. They were implemented in hope of pressurising Venezuela’s President – Maduro – into stepping down. Presumably, the sanctions will stay in play until this is fulfilled, therefore broadening their commodities seems to be a favourable move.

Switching from the Bolívar to the U.S. dollar and acknowledging the underlying issue of their high dependence on a – somewhat undependable – commodity in conjunction with other credible government interventions will work best to maximise the potential stabilisation of Venezuela’s economy in years to come.
