Limits-Factored?
Thank you. I understand that it's because of the (3-x) on bottom that makes it negative?
Limits-Factored?
lim as x approaches 3+ x^2+x-6/18-3x-x^2 I factored it into (x+3)(x-2)/(6+x)(3-x)
Inequalities
Two is greater than five? That's what I do not understand.. Thank you
Inequalities
solve (x-3)/(x+1) > 5 I get x < -2 every time, but it doesnt work when I plug it back in. (I plugged in -5)
Rational vs. Irrational
Okay thank you.
Rational vs. Irrational
Is 3.05313131313131313131313131... irrational or rational? Thanks.
Domain- Interval Notation
Thank you!
Domain- Interval Notation
Domain of g(x) g(x)= sqrt(3-(sqrt(25-x^2)) I got -5, -4, 4, and 5. I wrote it like [-5, -4] U [4, 5] I don't think that's right?
Chemistry
I'm working on a problem dealing with calculating the heat of vaporization for vapor pressures problem. By substituting the problems values into the Clausuis-Clapeyron equation I get: .642= (2.28x10-5) x Delta H vap (J/mol) However, from this point I don't know how to ...
Math
Same kind of problem. How to rearrange to put an equation in quadratic form. Example I'm given is 49.7= 2x^2 / (1.00-x)(2.00-x) which should come out to .920x^2 -3.0x + 2.0 but I can't figure out exactly how to get to there, especially how to get the x squared number.
