The 48 members of the glee club are trying to raise at least $6,000 so they can compete in the state championship. They already

ddd [48]

Step-by-step explanation:

48: the number of members

1,210: amount of money they already have

6,000: amount they need

by simply dividing the goal with amount of people, you will get the amount each person needs to make.

6000 ÷ 48 = 125

48x - 1,210 = 6000

x = how much each person needs to make

48 × 125 = 6000

i think this is what your looking for? if not just comment dont report and i will ask for more details.

The cosine of an angle is the x-coordinate of the point where its terminal ray intersects the unit circle. So, we can draw a line at x=-1/2 and see where it intersects the unit circle. That will tell us possible values of θ/2.

We find that vertical line intersects the unit circle at points where the rays make an angle of ±120° with the positive x-axis. If you consider only positive angles, these angles are 120° = 2π/3 radians, or 240° = 4π/3 radians. Since these are values of θ/2, the corresponding values of θ are double these values.

a) The cosine values repeat every 2π, so the general form of the smallest angle will be

... θ = 2(2π/3 + 2kπ) = 4π/3 + 4kπ

b) Similarly, the values repeat for the larger angle every 2π, so the general form of that is

... θ = 2(4π/3 + 2kπ) = 8π/3 + 4kπ

c) Using these expressions with k=0, 1, 2, we get

... θ = {4π/3, 8π/3, 16π/3, 20π/3, 28π/3, 32π/3}
