The kinetics of the catalytic decomposition of NH3 into N2 and H2 on a hot tungsten filament at 1100 °C was investigated by Kunsman. He measured the times (t1/2) required for half of NH3 to decompose at different initial NH3 pressures, as shown below: P (...

log(base 2)csc(x) = log(base 4)csc(4x^2) I tried doing the log(base a)b = logb/loga but I can't get past that because I'm not sure what to do after that. How do I set it up so I get like cscx=? or something so I'm able to solve for multiple values of x? t...

log(base 2)cotx - 2log(base 4)csc2x = log(base 2)cosx the answer should be x = pi/3, 5pi/3 not sure how to work it out though, any help? I tried canceling the bases but that led to a dead end.

Is this sentence below correct grammatically ? Thanks! Throughout the story a couple of crucial events take place, but we shouldn’t merely focus on these occurrences themselves, but rather on Edie’s assessment of them.

What punctuation is correct for this sentence? Comma or Semi-Colon? But these weren’t simply mashed; they were formed delicately by my mother’s hands But these weren’t simply mashed, they were formed delicately by my mother’s hands

Is this a complete sentence? Or should the comma be replaced by a semi-colon? Surely there are certain situations in which appropriate attire is necessary, so should we as women give in to that standard?

Preterite vs. Imperfect I'm just trying to clarify the differences. For example: 1. The food was delicious-imperfect? 2. The house was very big-imperfect? 3. The bump on his head was a tumor-imperfect? Are these right? or should they be preterite?

Well the original problem was the following but I worked it out to what I put here before: log(base 2)cotx - 2log(base 4)csc2x = log(base 2)cosx I switched the cosx and the csc2x and used properties of logs to get log(base 2)cscx, but maybe I'm wrong in d...

It's csc 2x, and I got it down to this before but I don't know if I can use your hint from there or if I should start from square one: log(base 2)csc(x) = log(base 4)csc(4x^2) Would that become the following? log(base 2)csc(x) = 2log(base2)csc(4x^2)
