Scientists studying a population of endangered bats find that the population is decreasing by 16% per year. The current population size is 1,800. What function models the number of years, f(n) , it will take the population to reach a size of n individuals? Replace the values of a and b in the equation to create the model.

f(n) = 1800(1-0.16n)

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
