Answer:
the height of the rock 3.2 seconds after it is propelled
Step-by-step explanation:
<u><em>The complete question is</em></u>
The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot
Let
t------> the time in seconds
h----> the the height of a rock after it is propelled by a slingshot in meters
we know that
For 
Find the value of h(t)
therefore
h(3.2) represent the height of the rock 
seconds after it is propelled
see the attached figure to better understand the problem
Answer:
C. 0 ≤ X ≤ 40
Step-by-step explanation:

_____
Personally, I might put the domain at 1 ≤ x ≤ 40, because there's no point in using the equation (or parking the bus) if zero people are going on the trip.
If 22% are sixth graders, then the rest must not sixths graders.
100% of the school - 22% sixth grades = 78% are not sixths graders
