Alyssa is an ecologist who studies the change in the fox population of the Arctic circle over time. She observed that the population loses \dfrac{1}{18} 18 1 start fraction, 1, divided by, 18, end fraction of its size every 222 months. The population of foxes can be modeled by a function, PPP, which depends on the amount of time, ttt (in months). When Alyssa began the study, she observed that there were 185{,}000185,000185, comma, 000 foxes in the Arctic circle. Write a function that models the population of the foxes ttt months since the beginning of Alyssa's study.

Step-by-step explanation:

This is a exponential modelling problem.

The population looses 1/18th of it every 2 months.

That in decimal is:

1/18 = 0.0556

in percentage, 5.56% lost every 2 months

So, remaining:

100 - 5.56 = 94.44%

in decimal that is

0.9444 (to 4 decimal)

Now, the equation modeled would be in the form:

Where

C is the initial amount (185,000)

I is the factor that we decrease by (we found to be 0.9444)

n is the months it decreases by that factor (so, n = 2 cuz every 2 months)

Now we substitute and write the exponential model equation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

answer: the answer is e
