Step-by-step explanation:
The open circle means that the point is not included in the solution set, and the arrow pointing left means that all numbers less than -2 are members.
In set-builder notation, each term has a special meaning. The braces enclose the members of the set.
Here's how you translate the notation,

Answer: The answer is D. P(t) = - 16t^2 + 100t / 3.2808

Answer:
138
Step-by-step explanation:
Hexagon total angle = 720
170+ 277 + 135 = 582
