Answer:
The equation i.e. used to denote the population after x years is:
P(x) = 490(1 + 0.200 to the power of x
Step-by-step explanation:
This problem could be modeled with the help of a exponential function.
The exponential function is given by:
P(x) = ab to the power of x
where a is the initial value.
and b=1+r where r is the rate of increase or decrease.
Here the initial population of the animals are given by: 490
i.e. a=490
Also, the rate of increase is: 20%
i.e. r=20%
i.e. r=0.20
Hence, the population function i.e. the population of the animals after x years is:
P(x) = 490(1 + 0.200 to the power of x
Answer:
The answer is 75 miles per hour
Step-by-step explanation:
225÷3=75 ( how many times 3 go into 225)
We can check to see if this answer is correct by multiplying 75 by 3 ( multiply 75 three times)
75×3=225
There for 75 is the correct answer

Answer:
x=14
Step-by-step explanation:
First bring the 6 to the other side and then bring the 4x to the other side to have 5x-4x=6+8 and combine the like terms and x equals 14.
Answer:
5 lines
Step-by-step explanation:
5 times 5 is 25 so 25 divided by 5 is 5 therefor your answer is 5
12-13 I hope this helps ;)
