ANSWER:

On solving equation by quadratic formula method, we get

D = b² – 4ac

(–5)² – 4 × 1 × 3
25 – 12
13

D > 0, so it has real roots.

Now, x = – b ± √D/2a

– 5 ± √13/2

So, Correct choice - [A] & [C].

Answer:

solving equation by quadratic formula method, we get:

D = b² - 4ac

=(-5)² - 4 × 1 × 3

=25-12=13

D> 0,

so it has real roots.

x=- b ± √D/2a

- 5 ± √13/2

Correct choice [A] and [C].

Given AB is tangent to circle C at point B, what is the circumference of circle C?

faltersainse [42]

Given:

Given that AB is a tangent to circle C.

The length of AB is (2r -1)

The length of AC is (r + 1) + r

The length of BC is r.

We need to determine the circumference of the circle C.

Value of r:

The value of r can be determined using the Pythagorean theorem.

Thus, we have;

$AC^2=AB^2+BC^2$

Substituting the values, we have;

$[(r+1)+r]^2=(2r-1)^2+r^2$

Simplifying, we have;

$(2r+1)^2=(2r-1)^2+r^2$

Expanding the terms, we get;

$4r^2+4r+1=4r^2-4r+1+r^2$

$4r^2+4r+1=5r^2-4r+1$

Simplifying the values, we have;

$4r=-4r+r^2$

Adding both sides of the equation by 4r, we get;

$8r=r^2$

$0=r^2-8r$

$0=r(r-8)$

Thus, $r=0 \ or \ r=8$

Since, the radius of the circle cannot be 0.

Hence, the radius of the circle is 8.

Circumference of the circle:

The circumference of the circle can be determined using the formula,

$C=2 \pi r$

Substituting r = 8, we get;

$C=2 \pi (8)$

$C=16 \pi$

Thus, the circumference of the circle is 16π

Hence, Option A is the correct answer.
