The picture in the attached figure
we know that
If a tangent segment and a secant segment are drawn to a <span>circle </span><span>from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment
</span>so
DC²=BC*CA-----> CA=DC²/BC
DC=25
BC=14
CA=25²/14-----> CA=44.64
CA=BC+BA----> BA=CA-BC----> BA=44.64-14----> BA=30.64
BA is the diameter
hence
<span>the length of diameter BA is 30.64----> round to the nearest tenth---> 30.6
</span>
the answer is
<span>the length of diameter BA is 30.6</span>

Since it has a negative discriminant, the quadratic equation that does not have a real solution is given by:
−4x2 − 4x − 6 = 0.
<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>A quadratic equation is modeled by:
The discriminant is:
The solutions are as follows:
- If
, it has 2 rational solutions.
- If
, it has 1 rational solutions.
- If
, it has 0 real solutions.
We want , hence, for equation -4x² - 4x - 6, we have that a = -4, b = -4, c = -6, hence:
Negative discriminant, hence it does not have a real solution.
