Id say its between a and c. your best bet would be a since you have to plug in 9 for y.
The answer is C
277 units^2
The correct answer is B) y = 120000x + 420000.
We multiply 120,000 by x since that is the cost per person per day, and x is the number of days. We add 420,000 because that is the one time cost of the round trip airfare.
If you convert 2/5 into a decimal which is 0.4 and multiply it by 100
you'll get 40 which means 2/5 is 40%
so 35% is less than 2/5
Step-by-step explanation:
Sin^2 (x) * Cos^2 (x) = {[1 - cos (2x)]/2}*{[1 + cos (2x)]/2}
Sin^2 (x) * Cos^2 (x) =[ 1 - cos^2 (2x)]/4
Sin^2 (x) * Cos^2 (x) = (1/4) - (1/4) * cos^2 (2x)
Sin^2 (x) * Cos^2 (x) = (1/4) - (1/4) * {[1 + cos (2*2x)]/2}
Sin^2 (x) * Cos^2 (x) = (1/4) - (1/8) * [1 + cos (4x)]
Sin^2 (x) * Cos^2 (x) = (1/4) - (1/8) - (1/8)* [cos (4x)]
Sin^2 (x) * Cos^2 (x) = (1/8) - (1/8)* [cos (4x)]
