A 3x3 matrix has a characteristic polynomial of degree 3. If all the elements of the matrix are real, then the polynomial has up to 3 distinct complex roots. If one of these roots is complex (in particular, has a non-zero imaginary part), then a second root would be that first root's complex conjugate. Then the remaining root has to be real.
Answer:
Step-by-step explanation:
Most tracks are 400 meters around, as measured in Lane 1; that's just a bit less than one-quarter of a mile. Here are some other measurements that it's helpful to know: 100 meters: the length of one straightaway. 800 meters: roughly ½ mile or 2 laps around the track
good luck, hope this helped
82,300 because you need to round it to the 100 place
