The game commission observes the fish population in a stream and notices that the number of trout increases by a factor of 1.5 every week. the commission initially observed 80 trout in the stream.

a. write the explicit formula for the trout situation. (+2)

b. make and upload a graph of the population growth. (+2) does the graph show a linear function or an exponential function? (+1) explain. (+2)

c. if this pattern continues, how many trout will be in the stream on the fifth week? (+1)

d. if this pattern continues, on what week will the trout population exceed 500? justify your reasoning. (+2)

A -

B - Graph given below

C - Number of trouts in 5th week are 607.2

D - Population of trouts will exceed 500 on the 5th week.

Step-by-step explanation:

We are given that,

The number of trout increases by a factor of 1.5 each week and the initial population of the trout is observed to be 80.

Part A: So, the explicit formula representing the situation is,

, where f(t) represents the population of trouts after 't' weeks.

Part B: The graph of the function can be seen below.

It can be seen that the function is an exponential function.

Part C: It is required to find the number of trouts in the 5th week.

So, we have,

i.e.

i.e. f(5) = 607.2

Thus, the number of trouts in 5th week are 607.2

Part D: We are given that the trout population exceeds 500.

It is required to find the week in which this happens.

So, we have,

i.e.

i.e.

i.e.

i.e.

i.e.

i.e. t > 4.5

As, t represents the number of weeks. So, to nearest whole, t = 5.

Thus, the population of trouts will exceed 500 on the 5th week.

step-by-step explanation:

3,750 deer

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.
