Given: f(x)=2x^2-x+1 g(x)=2 sin x h(x)=3^x Determine: a) f(g(x)) b) (h^-1 o f)(x) c) g(f(h(x)))) Please show steps, thank you very much.

A water heater is fueled by the combustion of propane as described by the following reaction: C3H8(g) + 5 O2(g) --> 3 CO2(g) + 4 H2O(l) a) Determine how much heat is released if 11.2 moles of propane are burned at 298 K and at a constant pressure of 1.00...

The most prominent line in the atomic spectrum of mercury occurs at a wavelength of 253.652 nm. What is the energy of 0.625 moles of photons associated with the most prominent line? Express answer in kJ. ANS: 295 kJ Please explain.. Thank you so much!

Oh your right! Now I see that, thanks so much!

2sin(2(3^x)^2 - 3^x + 1) 2sin(2(3^2x) - 3^x + 1) ??

Why would x=0?? And how are they equal??

The question ask for the value(s) of X

Where did you get the x+2 from?

Oh no problem :) and thank you so much for answering!

Got it, thank youu!

Thanks!
