Ive just moved to Vincent, CA (an unincorporated area in Los Angeles county) but my zip code is 91722 (part of City of Covina). I ve contacted the neighboring cities police departments (Covina, West Covina, Azusa, Irwindale) but they all responded that they are not responsible for my area.

Does it mean that I am screwed if I needed to contact the police for non-emergency assistance?

Hi guys

My new house has an avocado tree in the back yard. But I do not know how old it is. Anyone care to give an estimate? Thanks

Hey everyone, I'm running in to a problem.

I am trying to backup my Iphone to my computer and every time the phone keeps restarting half way through the process. Before it restarts it freezes with the "storage almost full" message on the screen, then a couple minute later it reboots itself.

I have about ~300mb free memory on the phone. I can't free up memory because they are all from photos I synced to the device and an attempt at unsycing would still cause my phone to reboot.

The specific problem I have is as follows:

The joint-density function is f(x,y)=1/(x^2y^2) and U=XY V=X/Y

Find the marginal pdf's of U and V.

So first I found the joint pdf of U and V 1/(2u^2v). I know the formula to find the marginal pdf's but how can I find the limits of integration?

Hi everyone, have you guys ever encountered the situation above and the package is still delivered?

I bought something from Amazon and the USPS # they gave did not check out. I would like some suggestion before I contact the seller, USPS, or Amazon Customer Service.

Thank you.

I am planning visit the Stanford Campus around 12/23-12/25.

I tried calling their office but they are closed for the holidays.

Thanks.

A disk of radius 26.0 cm is free to turn about an axle perpendicular to it through its center. It has very thin but strong string wrapped around its rim, and the string is attached to a ball that is pulled tangentially away from the rim of the disk. The pull increases in magnitude and produces an acceleration of the ball that obeys the equation a(t) = At , where t is in seconds and A is a constant. The cylinder starts from rest, and at the end of the third second, the ball's acceleration is 1.6 m/s^2.

Find the angular acceleration function of the disk with respect to time. Given A=0.5333m/s^2

I know the equation loss of P=I^2*(resistance/mile)*miles.

I want it to print at the user specified miles as well as in increments of -10 miles until 50 miles. (i.e. if user enters 70 it will print power loss a 70, 60, 50 miles ) .

Thanks

I tried substituting 5x+pi/4 for the Taylor series for Sine, but it seemed to be a dead end. Can some one help me for this problem? Thanks

I saw this on the no-no section in the DMV hand book, the penalty is $160.

My friend recommended me to this place he called the Costco Outlet. He does not know the actual name nor does he remember the address. All he said is that there is one in Azusa and it sells Costco products at half price. Thanks

My friend accidentally drove on to the Bus Way near the Union Station because he claimed that there was no signs indicating that it was a toll road. He is afraid that he will have to pay the fines. When he called the Fastrak hotline they weren't able to provide him with any information. Can anyone who have experience this give me some information? Thanks.

Here's a question in my book I know the answers but I don't know how to solve it:

A child weighting 320N want to use a pulley to reach an apple in the tree. He tied a chair weighing 160N to one end of the pulley rope and sits on it. He pulls on the rope's other end until the spring scale he attached reads 250N.

a.) What's the magnitude and direction of acceleration of the system.

b.) What's the force excreted on the child by the chair.

The answers are 0.408m/s^2 upwards and 83.3N respectively.

Enlightened Physics Scholars please help! Thank you

I live in Southern California hot and dry weather. Recently in my cupboard I found a half jar of oats, it has probably been sitting there for 7~8 years. I opened the jar and it smelled strongly of earth (dry mud or dirt) is that normal and safe to eat?

Just a simple Mechanics question I couldn't do:

A particle travelling at 1.5 m/s in water decelerates. The acceleration (a) is proportional to the velocity (v) of the particle and is modeled by a= -3v^2. Find the time (t) when the velocity of the particle is cut in half.

Thanks to anyone who can answer this.

Recently I discovered a problem: anytime when I try to safely eject my flash drive, the computer shows an error message stating that the drive is in use. My anti-virus software identified the program using the flash drive is Realplayer Downloading Manager. However I never opened that program nor does it show in the Task Manager so I don't know how to terminate it. Does anyone else have this problem and know a solution to this? Thanks.

I was stumped by my parent's question as we were driving up the I-5 from LA to SF. These trees are short maybe 5 feet tall and trimmed to look like pine tree. Anyone living in those are can identify them? ( I know it's not much to go on ). Thanks

Can some one please show me how to solve these 2 problems:

1. (i + j) x (i + k)

2. (i + j + k) x (3i + 4j -2k)

Thanks.

For the past 2 days everytime I try to shut down my computer an error message appears. The Message state that an application fails to startup and I should press ok to terminate it, after clicking ok the computer shuts down normally.

The message never specify what's the error nor what is the application that has the error so I really don't know where to start looking. I didn't download or install anything in the past few days nor visit any suspicious websites and I regularly check my computer for viruses.

I hope to solve this problem before any major problem happen to my computer.

Has anyone encountered such problems? Or have any possible solution to this? I don't want to take the computer to a repair shop if this is just a problem that I can solve. Thanks.
