The marginal cost of producing the xth box of CDs is given by 9 − x/(x^2 + 1)^2. The total cost to produce 2 boxes is $1,200. Find the total cost function C(x). I'm getting 9x-(1/(x^2 - 1))+1181.9 but i guess its wrong
how would you solve these two equations. ln x + ln(x+1)=1 ln(x+5) = ln(x-1) - ln(x+1)

How many equivalence points would be visible for a solution of 1.0M sulfurous acid titration. Is it just two because in H2SO3 there are two H+ ions?
I have everything right but the last question asking how many cases per week The consumer demand equation for tissues is given by q = (97 − p)^2, where p is the price per case of tissues and q is the demand in weekly sales. (a) Determine the price elasticity of demand E ...

Oh, ok well i came out with a pH of 5.22. pH = pKa + log A/HA. I came up with .15M as A and .05 as HA. So 4.74+log(3)= 5.22.
what is the resultig pH if 0.005 mol of NaOH is added to 100.0mL of buffer containing 0.010 mol acetic acid (CH3COOH,pKa = 4.74)and 0.010 mol sodium acetate (NaCH3COO)? (Assume the final volume is 100 mL) So i worked it out, i just need to double check the pH. Let me know what...
