Answer:
The correct option is B) To help people prepare for the future.
Step-by-step explanation:
The other three options are irrelevant to scientific research on environment .
Hence the correct option is B)
First you must know that for remarkable angles: cos (0) = 1, cos (π) = - 1, cos (π / 2) = 0, cos (3π / 2) = 0, cos (2π) = 1. Then, by simple substitution in the given formula, you can find the solutions of x. Which for the interval [0, 2π) are: x = π, x = pi divided by two and x = three pi divided by two.Attached solution.
