4. Bill travels 400 m east in 20 seconds and then travels 300 m north in 20 seconds. a) What is the total distance traveled?
b) What is the total displacement?
c) What was his average speed?
d) What was his average velocity?
What is the answer

Explanation:

Given that,

Bill travels 400 m east in 20 seconds and then travels 300 m north in 20 seconds.

(a) Total distance = 400 + 300 = 700 m

(b) Total distance =

(c) His average speed,

(d) His average velocity,

Hence, this is the required solution.

whichever one it is, it's definitely not one that you included on the list you provided.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
