Express your answer as a polynomial in standard form.

f(x)= −3x+6

g(x)= x2−x+5

Find: g(f(x))


  • Substitute: Replace every x in g(x) with (-3x + 6).
  • Setup: g(f(x)) = (-3x + 6)2 - (-3x + 6) + 5
  • Expand: (-3x + 6)2 = 9x2 - 36x + 36
  • Distribute: -(-3x + 6) = 3x - 6
  • Combine: 9x2 - 36x + 36 + 3x - 6 + 5
  • Simplify: 9x2 - 33x + 35

An engine cylinder’s volume is 0.75 L and the air-fuel mixture inside it is 1.00 atm. Calculate the pressure of the gas in the cylinder after the piston compresses the mix to 0.075 L.

(Double Points: Name the gas law being used) 


(P2 = 10 atm)

P1: (1.00 atm)

V1: (0.75 L)

V2 (Final Volume): (0.075 L)

Formula:
P2 = (P1)(V1) / (V2)


(*Boyle's Law)





Boyle's Law: (P1V1 = P2V2)

. Breaking down the CCC Definition of Sacrament: (1) define all bolded words, and (2) explain what each phrase means. 

  1. “Sacraments are efficacious signs of grace"

  2. “instituted by Christ, entrusted to the Church”

  1. “The visible rites by which the sacraments are celebrated signify and make present the graces proper to each sacrament.”

  1. “They bear fruit in those who receive them with the required dispositions.”



1. efficacious: does what it means to do, makes an effect

    grace: relationship, not something you get

*(Sacraments actually give you a relationship with Jesus)*

2. instituted: Rooted/Founded in what Jesus did in His earthly life

   entrusted: Administer/manage the sacraments, define specific matter and form

3.  visible rites: ritual (thing I do)

  the graces proper to each sacrament: sacramental grace- makes       holier in a particular way

4. receive: God is working and I am participating in His work; If God is working the amount of grace, does not depend on you. 

   required dispositions: The amount of grace I receive, does depend on me; more open/faith.

Balance these equations:

1. 1 Ca(OH)2(s) + 2 HCl(aq) ---> 1CaCl2(aq) + 2H2O(l)

2. 2 Ag2O(s) ---> 4 Ag(s) + 1 O2(g)

  • 1 Ca(OH)2(s) + 2 HCl(aq) ---> 1 CaCl2(aq)+ 2 H2O(l)
  • 2 Ag2O(s) ---> 4 Ag(s)+ 1 O2(g)

Explain the principle of Double Effect, including naming the four requirements an act must meet for Double Effect to apply.

Double Effect is when there is an infinite number of unintended consequences of any action. You are only morally responsible for consequences you intend/will. It is used to determine whether an action is morally permissible when it has both a good effect and a foreseeable bad effect. 

The 4 requirements: 

1. The object is good or neutral

2. You intend the good effect, not the bad one 

3. The good/bad effect happens at the same time

4. The good effect is equal/greater to the bad effect
