A deep sea hydrophone began recording for 180 seconds as soon as it sensed a sound greater
than the threshold intensity of 200 underwater decibels (dB). The sound intensity, I, in dB
reached a maximum at 60 seconds after recording and then gradually decreased for the next
120 seconds. If t is the number of seconds since the beginning of recording, which of the
following graphs in the tI-plane could model the sound?

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

found it xd it ok yt
