Answer:
--- Members
--- Non-members
Step-by-step explanation:
Given
Members
Non-members
increase
For the members, the equation is:
For non-members, the equation is:
Let w = cos(x)
The given equation turns into -5w^2 + 4w + 1 = 0. Use the quadratic formula to find that the two solutions, in terms of w, are:
The solution w = 1 leads to cos(x) = 1 which then becomes x = 0, x = 2pi, x = 4pi, etc. The general way to write this is x = 2pi*n where n is any integer. These angles are in radian mode.
The solution w = -0.2 leads to cos(x) = -0.2 which becomes x = arccos(-0.2) = 1.77215 approximately assuming your teacher wants the angle in radian mode. Unfortunately, I don't know the exact value of x here. There may not be an exact value, or finding this exact value may be well beyond the scope of this course.
The time taken is 
<h3>Distances</h3>
Given the following information:
- Distance from Neptune to Mars =
- Time is taken =
Get the time taken:
Time = Distance/Speed
Time = 
Time = 0.89 * 10^5
Time = 8.9 * 10^4hrs
Hence the time taken is

Answer:
Step-by-step explanation:
Let x = the number of pepper plants, then (x + 6) = the number of tomato plants. Since the ratio of tomatoes to peppers is 5:2, we have the following:
5/2 = (x + 6)/x
2x + 12 = 5x
12 = 3x
4 = x = the number of pepper plants
