Plus these six:
1. Write the equation for a circle of radius 9 whose center is at (-4,3)
2. Find two points on this circle by inputing values for either x or y and solving for the other unknown
3. Write the equation of a circle whose radius is the square root of 8 and center is at (2,-2)
4. Find the distance between (3,-2) and (7,-7). Craw a graph and use pythagorean theorem
5. Write the equation if (3,-2) were the center of the circle and (7,-7) were a point on the circles circumference.
6. Find the equation of a circle that has its center at (-1,4) and passes through the point (4-9)

Study Group Assignment for Chapter 2

Chapter Test / p. 78-79 / 1-20

Also the following:

21. Write the formula of a circle whose center is at (2, 3) and whose radius is 2.5 .

22. Find the y-intercepts of the equation the circle you gave above.

23. Suppose an earthquake was felt in Florida and the S-waves, traveling at 4km/sec, arrived 123 secs after the P-waves, traveling at 7.5km/sec. How far away would the readings indicate the epicenter or cause of the tremors was?

24. Write the formula for the circle which has a center at (-3, 5) and contains the point (2, -7).

25. Find two more points that would reside on this circle by setting to x = 4 .

Don't forget to bring individually your completed work and one registration form per group to the test for credit.
