The integral (with upper limit 3 and lower limit 0) of |x^2 -4| dx.

Notice that there are absolute value signs around the (x^2 - 4).

You are shelving books in a library. You lift a book from the floor to the top shelf. The KE of the book on the floor was 0, & the KE of the book on the top shelf is 0, so there is no change in KE. Yet you did some work in lifting the book. Is the work-Kinetic energy theorem violated?

& LAST question (some assistance please)

- A ball is throw straight up into the air. At what position is the KE a maximum? At what position is the gravitiational potential energy a maximum?

I'm not too smart when it comes to electric know how so maybe someone out there can help me out.

My breaker never tripped until I got an electric heater. I ran that thing for a few hours and while my computer on the same outlit went to sleep. Then I woke my computer up to use...pop... there went the lights.

The breaker has a 10 and it is powering my whole office. I guess that means this breaker is for 10 amps max?

The electrical heater is pulling 12.5 amps per the specs using 1500 watts on the heater so I guess thats why it's popping???
Too many amps???

Do I get an electrician to take out the 10 amp breaker and put in a 15 or 20 amp instead???

if you draw the diagram it will make it easier to see

BDA and BCA are right angles and AB is the bisector
so angle A will be split into two angles 1 and 2

Here is the problem:
(x+2)/3 + (x-5)/4 = 3.5

I'm not asking for a solution, just a bit of help for the beginning. I cannot remember how to deal with the (x+2)/3. I know that I have to multiply it, but I can't remember what I do once I multiply it. Say I were to multiply it by 6.. do I then write it out as (6x+3)/2 ? See this is the part where I get confused. I don't remember if I just multiply it straight across and come out with (6x+12)/18 or what I had in the first place. I hope you all can understand what I'm trying to ask assistance for; it's a bit hard to explain something that I do not fully understand myself. Thanks in advance. :)
