Answer:

  7 < y

Step-by-step explanation:

The relation you're interested in is ...

  (4.5 -2y)/5 < (2 -3y)/10

  9 -4y < 2 -3y . . . . . . . . . multiply by 10

  7 < y . . . . . . . . . . . . . . . .  add 4y-2

The value of the first fraction will be less than that of the second fraction for values of y greater than 7.

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}

Marcus is running a science experiment in which he measures the rate at which bacteria multiply. Every 15 seconds the bacteria d
lesantik [10]

Answer:

C. 20480

Step-by-step explanation:

so the equation is (60x3) divided by 15 because there are 3 minutes and 60 seconds in each minute and the bacteria doubles every 15 seconds so when you get your answer (12) that is how many times you will double 5.
