Find the discriminant and the number of real roots for this equation.

4x2 + 12x + 9 = 0

A. -144; one real root

B. -144; no real roots

C. 0; one real root

D. 0; two real roots

Answers

Discriminant and the number of real roots for this equation are 0, one real root.

What is discriminant?

Discriminant of a polynomial in math is a function of the coefficients of the polynomial.

The discriminant of a quadratic equation ax2 + bx + c = 0 is in terms of its coefficients a, b, and c. i.e.,

Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]

Given equation

[tex]4x^{2} +12x+9 = 0[/tex]

Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]

= [tex]\sqrt{12^{2}-4(4)(9) }[/tex]

= [tex]\sqrt{144-144}[/tex]

D = 0

Therefore, number of real roots is one.

Hence, discriminant and the number of real roots for this equation are 0, one real root.

Hey there!

The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent. The Isosceles Triangle Theorem states that the perpendicular bisector of the base of an isosceles triangle is also the angle bisector of the vertex angle.

Group of answer choices

A) to replace damaged and dying cells

B) to keep the cell membrane functioning

C) to release energy into the environment

D) to get rid of wastes and take in nutrients

Answers

Answer:

C, to realease energy into the environment

Step-by-step explanation:

Hope this helps :)

The reason is  to release energy into the environment.

the correct option is (C)

What is cell?

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions

As, Exchange of substances between a cell and its environment is mediated through osmosis, active transport and diffusion.

Osmosis is the process of diffusion of molecules from the region of higher concentration to the lower concentration through a semipermeable membrane. The cells absorb water by the process of endosmosis from its surrounding and water exits by the process of exosmosis.

Cells need to move water, materials for energy, waste materials, and other molecules across the cell membrane to help maintain homeostasis.

Also, to release energy into the environment.
