Answer:
16
Step-by-step explanation:
Multiplecation by the length width, and the height, then divide and its 16.
One meter is 3.28 feet, so anything shorter than that. A basketball, maybe a very young child?
I drew these, as I just did these in math not too long ago. When I shaded it, it was in all four quadrants.
The average rate of change formula is
f(b) - f(a)
arc = ----------------
b-a
Here, a= -10 and b = 10
(10)^2 + 9(10) + 18 - [ (-10)^2 + 9(-10) + 18]
Here arc = --------------------------------------------------------------
10 - (-10)
10^2 and -(-10)^2 cancel. 18 - 18 cancel.
90 - (-90) 180
This leaves us with arc = ----------------- = ------------- = 9 (answer)
20 20
