the amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. marco is studying the change in the amount of money in two accounts, a and b, over time.

the amount f(x), in dollars, in account a after x years is represented by the function below:

f(x) = 10,125(1.83)x

part a: is the amount of money in account a increasing or decreasing and by what percentage per year? justify your answer. (5 points)

part b: the table below shows the amount g(r), in dollars, of money in account b after r years:

r (number of years) 1 2 3 4
g(r) (amount in dollars) 9,638 18,794.10 36,648.50 71,464.58

which account recorded a greater percentage change in amount of money over the previous year? justify your answer. (5 points)

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages

i dont know the answer but here's a picture of a dog
