Barney is an ecologist who studies the change in the tiger population of Siberia over time.
The relationship between the elapsed time t, in decades, since Barney started studying the population, and the
number of tigers, N(t), is modeled by the following function:
N() = 710 (35)
Complete the following sentence about the rate of change in the tiger population. Round your answer to two
decimal places.
The tiger population loses
3/5
of its size every decades

Explanation:

The function is garbled and incomplete: the power is missing and the decaying factor seems to be 3/5.

Assume the power is a constant divided by the variable t. Then, the equation would have the form:

That function means that:

If n = 1, the power is t, which means that the popultion of tiger is reduced to 3/5 of its size every t decades.

If n = 2, the power is t/2 meaning that the popluation of tigers is reduced to 3/5 of its size every 2 decades.

If n = 3, the power is t/3 and the population of tigers is reduced to 3/5 of its size every 3 decades.

Assume n = 0.5, then the power is t/0.5 = 2t, and the population of tigers is reduced to 3/5 every half-decade, or 5 years.

answer: 25 is the correct answer

step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
