Solve: cos(2x-180) - sin(x-90)=0 my work: cos2xcos180 + sin2xsin180= sinxcos90 - sin90cosx -cos2x - sin2x= cosx -cos^2x + sin^2x -2sinxcosx=cosx I'm stuck here. I tried subtracting cosx from both sides and making sin^2x into 1- cos^2x, but I still can't seem to solve ...

How do I solve this? My work has led me to a dead end. tan(45-x) + cot(45-x) =4 my work: (tan45 - tanx)/(1+ tan45tanx) + (cot45 - cotx)/(1 + cot45cotx) = 4 (1-tanx)/(1+tanx) + (1-cotx)/(1+cotx) = 4 Then I found a common denominator, giving me this: (2-2cotxtanx)/(1+cotx+tanx+...

Does my work here look right? 3. One mole of an ideal gas expands adiabatically into a vacuum. Calculate q, delta-e, w, and delta-H for the process. q= 0 [adiabatic] w= -Pext(V2-V1) w= 0 delta-e = w + q delta-e = 0 + 0 = 0 delta-h= delta-e + P(delta V) delta-h= 0 + 0 = 0 does ...

suppose that the gas tank of a car holds 12 gallons and that the car uses 1/ 20 of a gallon per mile .let x be the nuber of miles the car has gone since the tank was filled? (1/20x)= 12 so now get x by itslef! (1/20x)/ (1/20)= 12/(1/20) x= 240! yeah I am good! that is good! ...

97x+1/4=4 okay well minus 4 from 1/4 wich gives you?? 97x= 15/4 now get x by itself by dividing 97 by 15/4 wow! 1). Subtract 1/4 from both sides 97x+1/4-1/4=4-1/4 97x=31/4 (3.75) 2). Devide both sides by 97 97x/97=3.75/97 <-or 3.75 devided by 97 x=?
