Step-by-step explanation: The drama club raised 150% of their goal, which is represented by choice c.
The proper way to calculate this percentage is to calculate how much they earned over the goal. They earned $150 over a goal of $300, so you divide 150 by 300 to determine the percentage.
150/300 = .5, or 50%
So, they earned 100% (300) plus 50% (150), for a total of 150% of the goal.
Sin 2 x + 2 sin x = 0 2 sin x cos x + 2 sin x = 0 / : 2 sin x cos x + sin x = 0 sin x ( cos x + 1 ) = 0 sin x = 0, cos x + 1 = 0, cos x = - 1; Answer: x = 0, or x = π
