Alake has a small population of a rare endangered fish. the lake currently has a population of 10 fish. the number of fish is increasing at a rate of 4% per year. when will the population double? how long will it take the population to be 80 fish?

1) After 17.673 years ( Approx) the population will be doubled.

2) After 53.019 years the population will be 80.

Step-by-step explanation:

1) Let x represents the number of years after which the population will doubled,

Since rate of interest = 4%

And, initial number of fish = 10,

Hence the fish after x years =

Hence, After 17.673 years ( Approx) the population will be doubled.

2) Let after y years the population will be 80.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
