ginevra is an ecologist who studies the change in the tiger population of siberia over time. the relationship between the elapsed time t, in years, since ginevra started studying the population, and the number of tigers, N(t), is modeled by the following function:
N(t)=537×(1/3)^t/2
complete the following sentence about the decay rate of the tiger population.
the number of tiger is reduced by a factor of 1/3 every years.

every 2 years

Step-by-step explanation:

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
