Is it possible For dogs to be gray

Yes, it is possible for dogs to be grey

Explanation:

Whippets are gray and they are a type of dog

Like humans, dogs tend to go gray as part of their natural aging process.

Explanation: Just like us, humans, dogs tend to go gray as part of their natural aging process. And just like us, as dogs get older, the pigment cells responsible for color (specifically, melanin) stop being produced; this causes the strands to come out at a lighter shade, like gray or white.

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
