**Answer:**

**Step-by-step explanation:**

We have given that:

There are 20 alligators in the swamp. Each year, the number of alligators increases by 25%. There are 25 crocodiles in the swamp. Each year, 10 new crocodiles join the swamp

**Part A:**

According to the above mentioned statement the function for representing the number of alligators and crocodiles in the swap throughout the year is:

Alligators = y=20(1.25)^x (x represents years)

**crocodiles: y=10x+25**

**Part B:**

Number of alligators after 4 years in the swap = y=20(1.25)^x

Number of alligators after 4 years in the swap = y=20(1.25)^4

**Number of alligators after 4 years in the swap=48.82**

This shows that about 48 to 49 alligators will be there in the swap after 4 year

** Number of crocodiles after 4 years in the swap = y= 10(4)+25 = 65**

**Part C:**

We will use the graph method to solve this part:

After approximately 7 years, the number of animals of each type will be the same, 95.

Answer:

O D. an = 2(5)"

Step-by-step explanation:

Given the expression/sequence below

2, 10, 50, 250, 1250, ...

O D. an = 2(5)"

The explicit formula is C

a0= 2*5^0= 2

a1=2*5^1= 10

a2= 2*5^2= 50

a3=2*5^3= 250

a4=2*5^4= 1250

Can you make is more Specific?

I don’t know the gap at the beginning but the answer is c
