BRAINLIEST AND 20 POINTS James is studying the change in the cost of two items, A and B, over time. The cost of these items may increase or decrease due to inflation or depreciation.

The cost c(x), in dollars, of product A after x years is represented by the function below.

c(x) = 72(1.25)^x

By what percentage per year is the cost increasing or decreasing? Show all your work to justify your answer.

Choose a second initial value that is 0.01 greater than the initial value from question 9. iterate it using the function, f, ten times. if necessary, you can round your results to the nearest ten-thousandth.

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?
