The price of fuel may increase due to demand and decrease due to overproduction, marco is studying the change in the price of two types of fuel, a and b, over time.
the price f(x), in dollars, of fuel a after x months is represented by the function below:
f(x) = 2.15(0.98)
part a: is the price of fuel a increasing or decreasing and by what percentage per month? justify your answer. (5 points)
part b: the table below shows the price g(m), in dollars, of fuel b after m months:
m (number of months) 1 2 3 4
g(m) (price in dollars) 4.19 3.98 3.78 3.59
which type of fuel recorded a greater percentage change in price over the previous month? justify your answer. (5 points)

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

is there a question here?

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
