We can model the function in that interval as a straight line of negative slope.
We have then that the average rate of change in that interval is given by:
r = (y2-y1) / (x2-x1)
Substituting values:
r = (- 4-4) / (2π-π)
Rewriting we have:
r = -8 / π
Answer:
the rate of change from x = π to x = 2π is:
r = -8 / π
C is the answer but your hot add me on snap sosa.adrian
For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
the equation that will help find the time it takes chelsea to get to school on the bus is:
45 * t = 2.5 * (1-t)
Note: the equation will have one solution.
