Math 150 – Fall 2015: Quiz 3 – Sections 1C, 1D, & 1E
Group Worksheet (5 pts):
Yes or No Section Number(5 pts):
(circle yes if this is the worksheet your group would like to be graded)
If this is NOT the group worksheet, print your name here:
(-10 pts if you don’t turn in an individual worksheet with your name in this blank)
For BOTH group and individual worksheets, print the names of all members of the group who attended lab
and contributed to the worksheet here (10 pts):
Directions: You may not use your class notes, book, calculator, cell phone, any electronic devices, etc.
Your grade will be determined by your final answer and the work to justify it. You must show all your work
to receive credit. Your group should turn in one group worksheet, and each individual should turn in their
own worksheet. Only the group worksheet will count as part of your grade.
1. (5 pts) Write the equation of a circle with center C(−2, 4) and radius 5 in standard form.
Standard Form:
2. Find the distance between A(−5, −4) and B(6, 3), and then find the midpoint of the line segment that
connects them. (You must simplify any radicals!)
(5 pts) Distance:
(5 pts) Midpoint:
3. Convert the equation to the standard form of a circle. Then find the center, radius, domain, and range.
3x2 + 3y 2 − 5x + 6y − 4 = 0
(12 pts) Standard Form:
(2 pts) Center:
(2 pts) Radius:
(2 pts)Domain:
(2 pts) Range:
4. (15 pts) If the distance between A(2, y) and B(7, 1) is 13 units, find all possible values for y.
5. (15 pts) If (−2, 4) and (2, 0) are endpoints of a diameter of a circle, write the equation for the circle in
standard form. (Hint: Find the center and radius).
