First period we reviewed for our test by doing some problems in groups. Question 1 as shown in the slides introduced some words that i have never heard of. First of all there were the words Perigee and Apogree;

Perigee means the closest point to something.

Apogree means the furthest point from something.

The first question asked "How does it take for the spaceship to go around the earth."

- To answer this you are trying to find the period or (B)

- The next question was "What are the distances at the Perigree and the Apogree?"

To find the distance for the Perigree you take D-A or 550-450 = 100

To find the distance for the Apogree you take D+A or 550+450 = 1000

Question 2 is explained in the slides posted from today.

__Period 2__

We did our per-test.

The test is on Wednesday people and we start our final unit tomorrow.

The next scribe is Jowell.
