I went to ST. Louis from Puerto Rico on Sept. 30 and it was hotter in St. Louis when I got there. Then the winter was much colder in St. Louis than in Conn. where my son lives. What is going on?

I am not complaining since I wanted to pass some time in colder weather and to enjoy the snow but this climate thing is crazy. Do you think it is just global warning or is the climate going totally out of whack? If it snows in Puerto Rico, I will be really worried.

I don't see a reason why any calendar should be on a different year than any other calandar. With a world connected by the internet it's downright backwards. The world needs a new calendar which connects everything.

I will name this new calandar the Sparkloomian Calendar. Today is 01-01-01 and at this exact moment, the Sparkloomian time is now 00:01.01

Matt's rectangular patio measures 9 feet by 12 feet. He wants to increase the patio's dimensions so its area will be twice the area it is now. He plans to increase both the length and the width by the same amount, x. Find x?

Note: i found the area for the original patio =108 and doubled that = 216 but then i divided 216 by 108 and got 2 doesnt really seem right. Help

1. A gun is fired vertically into a 2.00 kg block of wood at rest directly above it. If the bullet has a mass of 0.021 kg and a speed of 250 m/s, how high will the block rise into the air after the bullet becomes embedded in it?
2. A 1700 kg car moving south at 14.5 m/s collides with a 2500 kg car moving north. The cars stick together and move as a unit after the collision at a velocity of 5.46 m/s north. Find velocity of the 2500 kg car before the collision.
3. A moving object has a kinetic energy of 200 J and a momentum with a magnitude of 33 kg*m/s. Determine the mass and speed of the object.
4. A 68.3 kg student stands in the middle of a frozen pond having a radius of 5 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty he throws his 2.8 kg physics book horizontally toward the north shore at a speed of 6 m/s. How long does it take him to reach the south shore in seconds?

For a research grant, I need a reputable information source that provides the number of children who die each year from life-threatening/life-limiting illnesses (or at least children who are diagnosed with these conditions). I have found some statistics from the Organ Procurement and Transplantation Network, cancer websites, etc., but I'm still looking for more. Any suggestions on where I can look? I also have access to scholarly journal databases (i.e., PubMed, PsycInfo) if you know of any article references. Thanks!

please help me... I need to find the limit (as x --> 0+) of ln (x) / x; using L'hopital's rule if possible. However, as L'Hopital's rule requires a 0/0 or inf/inf solution and for the limits to be differentiable, and i'm coming up w/ -inf/0 as the original limit...I'm lost.

Thanks for any help you can offer me.

I am a beginner, so i don't know how to do much on it yet.

I have a graph made on the calculator that i am having problems at getting all of the graph to fit on the screen, even when i have zoomed out.

If someone could explain that to me and/or window dimension, x and y scale, and square zoom.
