Answer:

Step-by-step explanation:
When we have a point (a,b) on the unit circle, we can say that

<em>This is a property of the unit circle.</em>

From the point given
, now we can write the equation shown below and solve for x:

So, x = 1/2
Answer: x = 1/2
Step-by-step explanation:
We have that the point (x, (√3)/2)) is on the unit circle.
we can define a circle of radius R centered in the (0,0) as:
x^2 + y^2 = R^2
This means that:
x^2 + (√(3)/2)^2 = 1
x^2 + 3/4 = 1
x^2 = 1 - 3/4 = 1/4
x = √(1/4) = 1/2
So we have that x is equal to 1/2

Answer:
C (0,1)
D (0,0)
E (0,-1)
G (0,5)
Step-by-step explanation:
The x coordinate has to be a zero so that the point could be on the Y-axis
100 = 1 x 10^2
6,000 = 6 x 10^3
