it would be 6 3/8 because the common factor is 5
55x5 - 40x5
The third one down
Answer:
256
Step-by-step explanation:
i think it is 256.i hope it was that
Answer:
probably square root of 5
aerage rate of change is just the slope from the endpoints of teh interval
ie 
assuming you mean 
evalaute f(5) and f(1)
f(5)=480(0.3)^5=1.1664
f(1)=480(0.3)^1=144
average rate of change=(1.1664-144)/(5-1)=-35.7084
the average rate of change of the function on the interval x=1 to x=5 is -35.7084
