Answer:
The equation for the circle is:
Step-by-step explanation:
Here, let us assume the two end points of the diameter are:
P (3,-1) and Q (-2,-1)
Now, as we knew diameter is the chord that passer through the center of the circle.
⇒ Mid point of DIAMETER = Center coordinates of the Circle
Let us assume O(x,y) is the center of the line segment PQ.
So, by MID POINT FORMULA:
⇒ The center coordinates of the circle = O(0.5,-1) ...... (1)
Now, RADIUS = Half of DIAMETER
Using DISTANCE FORMULA:
So, Radius = 5/2 = 2.5 units
Now, the equation of circle with radius r and center coordinate ( h,k) is given as:
Substitute r = 2.5 and (h,k) = (0.5,0) we get:
Hence the equation for the circle is:
Answer:
b. a unique real solution
Step-by-step explanation:
A quadratic equation ax² + bx + c = 0 ,
Has two distinct real roots,
If discriminant,
Has two equal real roots,
If D = 0,
Has two imaginary roots or no real roots,
if D < 1,
Here. the given qudratic equation,
By comparing,
a = 4, b = 32, c = 64,
Hence, the equation has two equal real roots or a unique real solution.
i.e. OPTION 'b' is correct.
