Math
ah, thanks... i'm only taking "liberal arts math", so have only done a little bit of calculus. how did you get this part? H(.2559) = appr 319.7 H(.744) = appr 312.7

Math
H(t) = 0.013t^2 + 0.81t + 316 + 3.5 sin 2πt Ah, the formula should have an exponent!

Math
The formula should actually be: H(t) = 0.013t2 + 0.81t + 316 + 3.5 sin 2πt

Math
Could someone explain how to find which months during the year the maximum/minimum points occur for this problem occurs? I think it's around May and Oct, but I don't get how to determine that on the graph The National Oceanic and Atmospheric Administration (NOAA) has b...

Math
how did you determine the maximum and the minimum?

Math
NOTE - the formula should be: H(t) = 0.013t^2 + 0.81t + 316 + 3.5 sin 2πt

Math
Could someone explain how to solve this math problem? I've graphed it, but I'm not sure how to solve the rest of the questions. The National Oceanic and Atmospheric Administration (NOAA) has been measuring atmospheric carbon dioxide concentations (in parts per million)...

Math
Could someone explain what each part of this formula represents? H(t) = 0.058t^2 + 0.41t + 516 + 2.5 sin(2π)(t)

chemistry
What percentage of the Ba2+ in solution is precipitated as BaCO3(s) if equal volumes of 2.4*10^-3 M Na2CO3(s) and 1.1*10^-3M BaCl2(aq) are mixed
