Question

A population of 45 foxes in a wildlife preserve doubles in size every 10 years. The function y = 45 * 2 ^ x where x is the number of 10-year periods, models the population growth . How many foxes will there be after 20 years After 20 years there will be Foxes(Type a whole number.)

Answer 1

Answer: 180

Explanation:

Given

The population of 45 foxes doubles in 10 year period

Population follows
`y=45\cdot 2^x`

After 20 years i.e. x=2 Population is given by

`y=45\cdot 2^2=45* 4\\y=180`

Thus, there will be 180 foxes after 20 years
