A population of 35 foxes in a wildlife preserve quadruples in size every 13 years. The function y=35 * 4^x, where x is the number of 13-year periods, models the population growth. based on the model, how many foxes will be after 39 years?

There would be 2240 Foxes after 39 years

Step-by-step explanation:

The population of 35 foxes in a wildlife preserve quadruples in size every 13 years. The population growth is modelled by the function,

y = 35 * 4^x

Where

x represents the number of 13-year periods.

In a period of 39 years, the number of of 13-year periods is

39/13 = 3

Since the are three 13-year periods, substituting x = 3 into the function, it becomes

y = 35 * 4^3

y = 35 × 64

y = 2240

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
