    Why is this a single replacement reaction

    the equation from my textbook: 2k+2H2O yields 2KOH+H2 why? I thought that such reactions are when one element swaps with another but in this case, there is an extra H2

    Testing What score do I have on this AP Calc AB practice Exam?

    I've been self studying AP Calc AB over this past month, and I just took a practice AP Exam. It is the first AP Calc AB test in the princeton review's ap calc book 2010 edition. I got 31/45 on the MC and roughly 50% of the FRQ's correct. Could someone estimate what I got between 1-5? Thanks!

    Integral with multiple answers

    The question is ∫3cos25x dx. I tried to solve it 2 ways and got two different answers. Method A. ∫3cos25x dx =3∫cos25x dx u=5x 3∫cos2u (1/5)du/dx dx The 2 dx cancel out leaving 3∫cos2u (1/5)du= 3/5 ∫cos2u du= 3/5 ∫(1/2 + 1/2 cos 2u) du= 3/5( (1/2x)+∫1/2 cos 2u du)= 3/5( (1/2x)+1/2∫ cos 2u du)=...

    Is Calc 1 at CC enough to prep me for BC Calc?

    Here is the situation: I'm a junior taking Precalc right now and I hope to take AP Calc BC next year. My guidance counselor told me that the AP Calc BC curriculum at our school is laid out so that it picks up right after where Calc AB lefts off, so AP Calc AB is an absolute prereq to take BC at...
