<span>A line segment is described as a fixed distance along a line. This is because a line segment has a definitive start point and an end point, and it falls along one line.</span>
If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3. The correct option is D.
<h3>What is the equation of the circle with radius r units, centered at (x,y)?</h3>
If a circle O has a radius of r units length and it has got its center positioned at (h, k) point of the coordinate plane,
then, its equation is given as:
![(x-h)^2 + (y-k)^2 = r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%20%2B%20%28y-k%29%5E2%20%3D%20r%5E2)
The equation of unit circle is
![(x-h)^2 + (y-k)^2 = 1\\\\x^2 + \dfrac{\sqrt{3} }{3}^2 = 1\\\\x^2 + \dfrac{1 }{3} = 1\\\\\\x^2 = 1 - \dfrac{1 }{3} \\\\x^2 = 2/3\\](https://tex.z-dn.net/?f=%28x-h%29%5E2%20%2B%20%28y-k%29%5E2%20%3D%201%5C%5C%5C%5Cx%5E2%20%2B%20%5Cdfrac%7B%5Csqrt%7B3%7D%20%7D%7B3%7D%5E2%20%3D%201%5C%5C%5C%5Cx%5E2%20%2B%20%5Cdfrac%7B1%20%7D%7B3%7D%20%3D%201%5C%5C%5C%5C%5C%5Cx%5E2%20%3D%201%20-%20%5Cdfrac%7B1%20%7D%7B3%7D%20%5C%5C%5C%5Cx%5E2%20%3D%202%2F3%5C%5C)
Thus, x = √2/ 3
If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3.

Answer:
52/48 , or 1.083333333333333 hours.
Step-by-step explanation:
D - -x^2 + 3x + 7
To find this, first write out the equation:
(3x + 1) - (x^2 - 6)
Distribute the negative into x^2 and -6 so you're equation now looks like this:
3 x + 1 - x^2 + 6
Combine like terms and arrange the equation into ax^2 + bx + c to get the final answer of:
-x^2 + 3x + 7
Hope this helps!
