Park rangers released 4 fish into a pond in year 0. each year, there were three
times as many fish as the year before. how many fish were there after x
years? write a function to represent this scenario.

y (x) = 4 (3)∧x

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Park rangers released 4 fish into a pond in year 0. Each year, there were three  times as many fish as the year before.

We have to apply the exponential growth expression:

y (x)= ab∧x

Where:

a= initial amount

b= growth factor

x = number of years

Replacing with the values given

y (x) = 4 (3)∧x

Feel free to ask for more if needed or if you did not understand something.

d is correct

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
