Any Help Will be Appreciated. Thanks.

Talia is holding the garden hose at ground level and pointing it obliquely so that it sprays water in a parabolic path 2 meters high and 8 meters long. Find, using g= 10m/s^2, the initial speed and angle of elevation, and the time each droplet of water is in the air. Where is the latus rectum of...

Thnx Drongoski. This question is from Cambridge 3Unit textbook, from development section. Cambridge 3Unit sometime has 4Unit stuff in it.

The velocity of a particle is proportional to its displacement. When t=0, x=2, and when t=10, x=4. Find the displacement time function, and find the displacement when t=25. The answer is 2^1/10t+1. and the answer to second part is 8 underroot 2.

Yes, when i solve the equation i get stuffed up answer. I am doin something stupid.

I used x=c+acos(nt+e). And i still dont get the right answer

The rise and fall in sea level due to tides can be modelled by a SHM. On a certain day channel is 10m deep at 9 AM when it is low tide, and 16M deep at 4PM when it is high tide. If a ship needs 12M of water to sail down a channel safely, at wat times between 9AM and 9PM can the ship pass...

f(x) = 1-sinx/cosx. Find f'(x). I used the Quotient rule, but cant get right answer. The right answer is -1/1+sinx . Any help would be appreciated. Here is my attempt: = cosx.cosx-(1-sinx).-sinx/(cosx)^2 = -cos^2x + sinx(1-Sinx)/(cosx)^2 I dunno wat to do after this

Our teacher told us that Shawshank Redemption, is really popular text and is very common. :confused:
