the value of P(7), given P(x) = negative4(x minus 15)2 + 2 is 1721.
The problem above can be solved using the ideal of polynomial.
<h3>What is a Polynomial?</h3>
Polynomials are mathematical expressions whereby the highest degree of their unknown is 2 and above.
Given:
- P(x) = negative4(x minus 15)2 + 2
Expand the expression
- P(x) = -4(x²-30x+225)+2
- P(x) = -4x²+120x+900+2
- P(x) = -4x²+120x+902
To find P(7), we subtitute 7 as the value of x in the expression above
- P(7) = -4(7²)+120(7)+909
- P(7) = -28+840+909
- P(7) = 1721
Hence, the value of P(7), given P(x) = negative4(x minus 15)2 + 2 is 1721.

The concentrations of the species at equilibrium is obtained from the ICE table.
<h3>What is equilibrium constant?</h3>
The equilibrium constant shows the extent to which a reactant has been converted into products. A large equilibrium constant means that most of the reactants are converted into products The question is incomplete as the details as missing.
However, for a hypothethical reaction; nA + mB ⇄ xC + zD, the equilibrium constant is obtained from; K = [C]^x [D]^z/[A]^n [B]^m. The concentrations of the species at equilibrium is obtained from the ICE table.

Explanation:
autonomic- role in your physical responses in situations of stress
the autonomic nervous system is divided into two systems: sympathetic and parasympathetic. SNS (sympathetic) is responsible for your fight-or-flight: it signals your adrenal glands to release the hormones epinephrine (adreneline) and cortisol (endocrine system). these two hormones trigger many reactions of autonomic nerves (dilated blood vessels, faster heartbeat, etc). SNS is a pretty sudden response which triggers your reactions and controls fight-or-flight. (im pretty sure i mean this is what i remember sorry if this didnt help)
