7.8 x 10 to the forth power divided by 8 x 10 to the 1 power

It is 975

Step-by-step explanation:

Step 1- 7.8x10^4= 78,000

Step 2- 8x10^1= 80

Step 3- 78,000/80= 975

Conclusion is that (7.8x10^4)÷(8x10^1)= 975

  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).
