What is the answer (1.5*10^5)(4*10^9)

6 × 10¹⁴  

Step-by-step explanation:

   (1.5 × 10⁵) (4 × 10⁹)         Collect the exponential terms

= (1.5 × 4) × (10⁵ × 10⁹)      Do the exponential calculations separately

=  6 × 10¹⁴

  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).
