Step-by-step explanation:
Given function:

where:
- h = height (in feet)
- t = times (in seconds)
Rewrite in the form 
The quickest way to do this is to expand
and compare coefficients with the original function.

Comparing coefficients with 



Therefore, substituting the found values into the equation:

Answer: first one
Step-by-step explanation:
The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.
