Kevin is observing the population of the fish he put into a pond. he built a pond and populated it with 500 fish. the population of the fish doubles every year. use x to represent the number of years and y to represent the population of the fish.

Here we will use exponential form, which is

Initial value, y0 = 500

Double of 500 = 1000

Required equation is

  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.

hi, i am not sure about this one but i think its d,

hope this !
