Let A = (3, 4), B = (0, −5), and C = (4, −3). a) Find equations for the perpendicular bisectors of segments AB and BC, and coordinates for their common point K.

b) Calculate lengths KA, KB, and KC.

c) Why is K also on the perpendicular bisector of segment CA?

d) A circle centered at K can be drawn so that it goes through all three vertices of triangle ABC. Explain. This is why K is called the circumcenter of the triangle. In general, how do you locate the circumcenter of a triangle?

D

Step-by-step explanation:

So we know that the shelf is 9 and 3/4 inches long.

Each move is 3/8 wide.

Thus, to find the number of movies to would fit, divide 9 3/4 and 3/8.

First, convert 9 3/4 into an improper fraction:

So, divide:

Keep, change, flip:

Multiply straight across:

Simplify:

So, our answer is D
