<=> cosx = +1/2 or cosx = -1/2;
cosx = +1/2 => x = +π/3 + 2kπ, where k is an integer or x = -π/3 + 2kπ, where k is an integer;
cosx = -1/2 => x = +2π/3 + 2kπ, where k is an integer or x = -2π/3 + 2kπ, where k is an integer;
Answer:
(1) Reuse; (2) Recycle ; (3) Reduce
Step-by-step explanation:
The ideal sequence would be:
1) Use it again (reuse) if the object still serves its intended purpose/s
2) If not possible to the used again, send it to a recycling plant to extract from it items/parts/substance of utility for other new products
3) if it cannot be reused or recycled, the last option will be to reduce it completely.
Answer: The answer is 3.77.
Explanation: Since 0.10 is 10 times smaller than 1, we know that if we divide 37.7 by 10, we will get the same answer as 0.10 x 37.7.
