Answer:

The equation for the circle is (x-0)^2+(y+3)^2=25

Step-by-step explanation:

The radius is half the diameter.  To find the length of the diameter we need to calculate the distance that (3,1) is to (-3,-7) which is sqrt(6^2+8^2)=10 .

The radius is therefore 10/2=5.

We also need the center of the circle (the midpoint of a diameter is the center of a circle).  So we just need to average the x's and y's to find the midpoint between (3,1) and (-3,-7) which is (0,-3).

The equation for the circle is (x-0)^2+(y+3)^2=25

I just plugged my info into (x-h)^2+(y-k)^2=r^2

where (h,k) is center and r is radius

Answer:

C

Step-by-step explanation:

The best way to solve this is to transfer -217 to the other side. So add 217 to both sides

0 ≤ 7 + 217 - 28v                   Combine

0 ≤ 224 - 28v                        Now add 28v to both sides

28v ≤ 224                             Divide by 28

28v/28≤224/28

v ≤ 8

You should have 2 questions on your mind.

  1. Why go to all the trouble of putting things on the opposite sides?
  2. What is the answer

1. You so all that trouble so that you don't have to switch the < to >. As long as you have the letter and its coefficient > 0, then you are going to be right.

2. The is v is less than or equal to 8.  That's C
