Answer:
E
Step-by-step explanation:
E
For x = 10, f(x) = f(10) = 0.01(2)^10 = 10.24
For x =
17, f(x) = f(17) = 0.01(2)^17 = 1310.72
Now using
formula for the calculation of average rate of change of f(x).
(f(b) –
f(a)) / b – a = (f(17) – f(10)) / 17 – 10 = (1310.72 -10.24) / 7 = 185.78

correct.</span>
Step-by-step explanation:
let x represent the bus
6x + 21 = 195
6x = 195 - 21
6x =174
x = 29
%change=100(final-initial)/initial
In this case:
%change=100(3.18-2.56)/2.56
%change=100(0.62)/2.56
%change=62/2.56
%change=775/32%
%change=24.21875%
%change≈24% (to nearest whole percent)
