The grass in jamie's yard grew 16 centimeters in 10 days. it was growing at a constant rate.

how many days did it take the grass to grow 1 centimeter?

0.625

Step-by-step explanation:

As the excerpt says that the yard grew 16 centimeters in 10 days at a constant rate, you can use a rule of three to determine how many days it took to grow 1 cm:

10 days → 16 cm

    x      ←   1  cm

x=(1 cm*10 days)/16 cm

x= 0.625 days

According to this, the answer is that it took 0.625 days for the grass to grow  1 centimeter.

  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).
