I did respond....you never posted what you thought the answers were.......
Nickolas....if you cannot get ANY of these......or at least TRY, after all of your postings and all of the answers given to you, you are in a course that is too advanced for you....you may need to back down a couple of course levels and re-tool before taking on this level.
Just add the fxns together x^3 - x + x^3 + 2x^2 -10 =.............. I think YOU can do THAT !
F rate 1 lb / 20 min
T rate 1 lb /30 min
3 / (1/20 + 1/30) = 36 minutes
You submitted 'If ........... when b = 3' Something is missing in the ........ position ....soemthing like ' a = 45'
Convention dictates the 'i' = iitial 'f' = final in a lot of chemical, physics etc equations
The ΔH is a positive change in endothermic reactions, and negative in heat-releasing exothermic processes.
ΔH is change in enthalpy = Hf-Hi For this to be NEGATIVE Hi must be greater than Hf so 'C'
If you 'read' the graph from L to R....which sections are going downward?
[-8,-4] [0,8]
a^2 = k/b^3 I think you left some info out...... when b=3 what is the given value of 'a' ?
(x^2-16) / (x^2-6x+8) =
(x-4)(x+4) / ( x -4)(x-2) (x cannnot equal 4)
The numerator and denominator (x-4)'s cancel and you are left with:
(x+4) /(x-2) x cannot equl 4 or 2
