For this velocity-time graph in which time interval is the object moving toward the reference point? a. 7 to 11 s b. 0 to 6 s c. 11 to 20 s d. 6 to 7 s

D. 6 to 7 s

Explanation:

When object is moving away from its reference point then its motion is known as positive motion

And when object moves towards the reference point then its motion is termed as negative motion because here the distance with respect to reference point is decreasing with time

so by the graph we can say that

object velocity is positive between

t = 0 to t = 6 s and t = 12 to t = 20 s

so in above interval of time it is moving away

while during time interval of t = 6 s to t = 7 s the motion its velocity is negative and hence it will move towards reference point

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

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.
