Answer:

See answers and explanations

Step-by-step explanation:

A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0

B) Since the discriminant is 0, this means the equation only has one root.

C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)

The volume of cone B will be 6 cubic units.

<h3>What is the volume of the cone?</h3>

Let h be the height of the cone and A be the base area of the cone.

Then the volume of the cone will be

Volume = (1/3) × A × h

Consider cone A and cone B.

The bases of the cones are congruent.

The height of cone A is 4 times larger than the height of cone B.

$\rm h_a = 4h_b$

The volume of cone A is 24.

24 = (1/3) Ahₐ

Then the volume of the cone B will be

$\rm V = (1/3)Ah_b$

Simplify the expression, then the volume will be

V = 1/4 x (1/3)Ahₐ

V = 1/4 x 24

V = 6 cubic units

The volume of cone B will be 6 cubic units.

More about the volume of the cone link is given below.

What is the value of b2 - 4ac for the following equation? 5x2 + 7x = 6

shtirl [24]

B²-4ac?

5x²+7x-6 = 0 
the form is ax²+bx+c = 0 

a=5, b=7, c=-6 

The discriminant D = b²-4ac 
= 7² - 4(5)(-6) = 49 + 120 
= 169
