There are an infinite number of solutions, so I don't plan to list them all.
I'll list two of them, and then describe how to get all of the rest.
You said that <u>2cos(x) - 1 = 0</u>
Add 1 to each side: 2cos(x) = 1
Divide each side by 2: cos(x) = 1/2
The angles whose cosine is 1/2 are 60 degrees, 300 degrees,
and any multiple of 360 degrees added to either of those.
Answer:
Step-by-step explanation:
Five of Peak Cinema's theatres are medium-sized (98 seats) and five are small (half of 98 = 49 seats).
Their total number of seats is
5 × 98 + 5 × 49 = 490 + 245 = 735 seats
Add the separate iMax theatre and the total capacity of the complex becomes
735 + 218 = 953 seats
Answer:
35
im almost positive the answer is 35 but if I'm wrong then I need to repeat some grades
