Answer:
![\frac{7\sqrt{65}}{65}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5Csqrt%7B65%7D%7D%7B65%7D)
Step-by-step explanation:
Cosine is the ratio of the side adjacent to the angle and the right triangle hypotenuse.
B =
= ![\frac{7\sqrt{65}}{65}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5Csqrt%7B65%7D%7D%7B65%7D)
Since, population of species A is represented by : ![P=2^{x} +19](https://tex.z-dn.net/?f=P%3D2%5E%7Bx%7D%20%2B19)
Let us find the population of species A, at the end of week 1:
i.e., x = 1
i.e., ![P(1)=2^{1} +19](https://tex.z-dn.net/?f=P%281%29%3D2%5E%7B1%7D%20%2B19)
i.e., ![P(1)=2 +19](https://tex.z-dn.net/?f=P%281%29%3D2%20%2B19)
i.e., ![P(1)=21](https://tex.z-dn.net/?f=P%281%29%3D21)
Also, since population of species B is represented by : ![P=3^{x} +18](https://tex.z-dn.net/?f=P%3D3%5E%7Bx%7D%20%2B18)
Let us find the population of species B, at the end of week 1:
i.e., x = 1
i.e., ![P(1)=3^{1} +18](https://tex.z-dn.net/?f=P%281%29%3D3%5E%7B1%7D%20%2B18)
i.e., ![P(1)=3 +18](https://tex.z-dn.net/?f=P%281%29%3D3%20%2B18)
i.e., ![P(1)=21](https://tex.z-dn.net/?f=P%281%29%3D21)
Thus, at the end of 1 week, species A and species B will have the same population.
Hence, option D is correct.
