Answer:
v - r
------ = a
t
Step-by-step explanation:
Starting with v = r + at, subtract r from both sides, so as to isolate the 'at' term:
v - r = r - r + at, or
v - r = at
Next, divide both sides by t, to isolate a:
v - r
------ = a
t
To get the average rate of change (ARC) of f(x) over [x1, x2], we use the formula:
ARC = ( f(x2) - f(x2) ) / (x2 - x1)
From the graph
f(2) = 4
f(-2) = 4
Plugging in the values into the formula:
ARC = (4 - 4) / (2 - (-2) )
ARC = 0
The points connecting (-2,4) amd (2,4) is a horizontal line that is the rate of change is 0.
Number 3 is D, number 4 is B, number 5 is B
