I understand it has made modern life easier, but some biochemical pathways are so complex that you cannot treat one problem without causing another.

I have been having terrible reception (pixeling, channels not coming in at all, my voice sounding robotic on the phone or people can't hear me at all) w/my digital cable/phone, and Comcast has told me it's due to "solar flares", occuring because of the fall solstice, which is due to end today. Is this true or are they coming up with more lame excuses? I can't find any "fall solstice" when I search for it. I have had a Comast worker at my house 3 times in 2 weeks and they tell me everything is just fine. DON'T EVEN GET ME STARTED ON COMCAST!!!!! I have heard everything from it must be a fluke to it's squirrels chewing the lines and now that it's solar flares. I am getting extremely frustrated and I'm planning on heading out there tomorrow to give them a piece of my mind.

I asked this question before but I think it was unclear.
I mean show how like this, a case I understand:

i*√9 = √(-1)*√9 = √((-1)*9) = √(-9)

Start from the left, and go to get the result on the right. Here's my attempt, following the above:

i*√(9*i) = √(-1)*√(9*i) = √((-1)*(9*i)) = √(-9*i)

But this is wrong, somehow I should end up with -√(-9*i) but I don't see how. What is the missing step. Thanks.

is have this equation:
(-2x^3 + 7x^2 + 22x - 48) / (2x^2 - 4x - 16)

in order to find the horiz. asymptote, you need the dominant terms in the numerator and denominator, right?
so wouldnt they be -2x^3 and 2x^2??? is this right?
what are the horizontal asymptotes? are there any??

A soda glass has the shape of the surface generated by revolving the graph of y=6 x^2 on [0,1] about the y-axis. Soda is extracted from the glass through a straw at the rate of 1/2 cubic inch per second. How fast is the soda level in the glass dropping when the level is 3 inches? (Answer should be implicitly in units of inches per second. Do not put units in your answer. Also your answer should be positive, since we are asking for the rate at which the level DROPS rather than rises.)

if you could talk me through it or give me hints about it that'd be great. the thing that really throws me off is where it says it has the "shape of the surface"..?????

Suppose that a population of adults is surveyed to number the measure the number of hours per week spent on home computers. In the survery, the number of hours is normally distibuted with a mean of 7 hours and a standard deviation of 1 hour.

Find the % of adults that spend more than 4.9 hours on a home computer per week.

If 150 adults are randomley selected, about how many would you expect to say they spen less than 5.4 hours per week on a home computer?
