Answer:
c
Step-by-step explanation:
Given that:

since cos (kπ) = 
Then, the series can be expressed as:

In the sum of an alternating series, the best bound on the remainder for the approximation is related to its
term.
∴




2x + 4y + 2 = 3y + 5
2x + 4y - 3y + 2 - 5 = 0
2x + y - 3 = 0
1 lb = 0.45 kg
52 lb= 0.45 * 52
52 lb= 23.4 kg
