What was the intensity of the earthquake in Chile?

• 630,957.34

According to scientists what happened to the Earth during this earthquake?

• According to scientists the earthquake ripped the Earth at 2 miles per hour, and moved an entire town.

Physics

1. We threw two objects from the height of three feet and timed from when they left our hand until they hit the ground.

2. -16(.78)^2 + v(.78) + 3 = h

    -16(.93)^2 + v(.93) + 3 = h

3. Velocity for bag: 8.6 ft per second. for circle ring: 11.6 ft per second

4.  -16t^2 + 8.6t + 3 = h

     -16t^2 + 11.6t + 3 = h

5. At .27 seconds the bag reached it's maximum height. At .36 seconds the circle ring reached it's maximum height.
6. The bags maximum height was 4.2 feet. The maximum height of the circle ring was 5.1 feet.
    Using both equations find the vertex. The "x" is the time when it hits it's maximum, and the "y" is the maximum height

Data shows that the users have been going up the same rate over the past five years, it is a positive correlation. It it important to be able to analyze  regression because if you couldn't you wouldn't be able to understand a lot of information. If you couldn't understand how to analyze it you also wouldn't be able  to make any data of your own. We use it in everyday life. In real life situations usually the slope is something like how much more money you will get per year and such.

Defining a Function

A function is when you  depend on one variable to get another one. Functions are used in the real world in situations such as passwords. It's important to understand how functions work because it is a very big part of math today.

I'm in algebra two and we're making our own number game that turns out to be an algebraic equation. The answer you get should always turn out the same no matter which one you start with.


My Game:

1. Pick a number

2. Add 4

3. Multiply by 2

4. Subtract 6

5. Divide by 2

6. Subtract Original






Solution: Should always end with the number 1.
