To find the temperature at 9:00 PM, we need to subtract 16.2 degrees from the initial temperature of 14°F.
14°F - 16.2°F = -2.2°F
Therefore, the temperature at 9:00 PM in Antarctica was -2.2°F.

To evaluate the expression 4 and 1/2 - 2 - 5 and 2/3:

First, convert all the mixed numbers to improper fractions:
4 and 1/2 = 9/2
5 and 2/3 = 17/3

Rewrite the expression:
9/2 - 2 - 17/3

To subtract fractions, we need to have a common denominator:
The common denominator for 2 and 3 is 6.

Rewrite the fractions with the common denominator:
(9/2)*(3/3) - (2)*(3/3) - (17/3)*(2/2)
27/6 - 6/6 - 34/6

Combine the fractions:
(27 - 6 - 34)/6
-13/6

Therefore, the evaluation of the expression is:
-13/6, which is approximately -2 1/6.
