Could you show me how to do these math systems and show your work so i understand how to do them. 1) 3x+2y+4z=19 2x-y+z=3 6x+7y-z=17 2) 5x+8y+6z=14 2x+5y+z=12 -3x+6y-12z=20 3) x^2+2xy-2y^2=-11 x^2+xy-2y^2=-9
In Problems 1 to 5 we will work through example of QFTM for M = 6. Problem 1: What is w? You can use e, pi, and M in your response. Please do not subtitute 6 for M. Specify the probability amplitudes. You should use w to denote w, but please fully simplify your answer such tha...
a) impulse = Force * time of interaction i = 950N *.0044s = 4.18N-s don't know how to do B
THANK YOU SO MUCH! :D
The problem is 3x^2 - 26 + 35 (We have to factor it!) So, I did the problem, but I'm not sure how to write the final answer. This is what my problem looks like so far: 3x^2 - 26 + 35 (3x^2-21x)-(5x+35) 3x(x-7)-5(x+7) and this is where I have the problem. I know I need to p...
A sports car moving at constant speed travels 120 m in 5.1 s. If it then brakes and comes to a stop in 4.0 s, what is its acceleration? Express the answer in terms of g's, where g = 9.80 m/s2. (Take the positive direction to be the direction of travel.)
Calculate the equilibrium constant at 25 C for CH4 + 2 H2O --> CO2 + 4H2 given: delta G for CH4 = -50.81 H2O = -228.6 CO2 = -394.4 H2 = 0
