So long story short, I have a friend who wants me to help her learn how to factor cubic polynomials. Normally I would just fess up and say I don't remember but it's something I'd like to review myself and lessons online aren't the clearest. Here's one of the questions: 2x3+3x2-8x+3 I...

So a more appropriate conclusion would be that the rays are more concentrated when they are closer to the plant?

I'm doing a report for biology about the relation betweem light intensity and photosynthetic rate. My results showed that as light intensity decreases, so does oxygen production. I said in my discussion that light rays that must travel longer distances will lose energy and appear dimmer than...

I have 3 homework questions that I need help with: Q1 X-rays having an energy of 543 keV undergo Compton scattering from a target. The resulting Compton shift is 3.83x1E-13 m. Find the energy of the recoiling electron. (units: keV) Q2 Find the maximum fractional energy loss for a 0.491...

so using that, how would I go about solving this problem?

Those don't ring a bell. How would I go about doing one of these?

Homework Statement Vector A has a magnitude of 8.00 units and makes an angle of 45.0° with the positive x axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x axis. Using graphical methods, find (a) the vector sum A + B and (b) the vector difference A - B...
