Homework Statement A population of 500 bacteria is introduced into a culture and grows in number according to the equation P(t)=500(1+(4t/(50+t2), where t is measured in hours. Find P'(2), an interpret the results. Homework Equations The Attempt at a Solution I used the product...

387.3. I think I actually understand it now. because the LCMS will show the mass +1 and then the bond with water was broken, which caused the weight to be 18 less than what we expected.?

Homework Statement Our assignment was to determine the structure, or sub-structure of our mass observed in the LCMS result. The number we got was 369.3. I am not really sure what to do with this at all. She gave us the structure of cholesterol, but I'm not sure where to add things on...

Homework Statement Place the following in order of decreasing magnitude of lattice energy. KF, MgS, RbI I'm not really sure how to do this without looking up the lattice energy values with each. And I don't think that is what our teacher wants us to do

Homework Statement Determine the electron geometry and molecular geometry or the underlined carbon in CH3CN. A) tetrahedral/tetrahedral B) linear/trigonal planar C) trigonal planar/bent D)linear/linear E)trigonal planar/trigonal planar I'm not really sure how to structure this...

oh yeah the chain rule! i definitely need to remember that! thanks!

oh, ok so it's right. I did that problem six times because I thought I was doing it wrong haha thank you! and also thank you for correcting me on the terms! :)

Homework Statement Use the definition of a derivitive to find f'(x). f(x)=1/(1-4X) Homework Equations Lim as h approaches 0 [f(x+h)-f(x)]/h The Attempt at a Solution I know that the answer is supposed to be -1/(1-4X)2 but I keep getting 4/(1-4X)2. This is what I have done so far (I...
