Tank #1 had 200 gallons in it and losing 2 gallons each minute. Tank #2 has 60 gallons in it. How long will it take for both tanks to have the same amount of water in them.

  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).

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
