Pls answer quick the following is the question

Before 2006, while Pluto was still considered a planet, people used this saying to remember

the nine planet names: “My very excellent mother just sent us nine pizzas.”

Come up with a new sentence to help remember the eight planet names, in order

Mother's Visit Evoked My Junior Sister's Unseen Nicenes

Explanation:

Mother's  - M - stands for Mercury

Visit          - V - Stands for Venus

Evoked     - E - Stands for Earth

My             - M - stands for Mars

Junior         -J - stands for Jupiter

Sister's       -S- Stands for Saturn

Unseen      -U - stands for Uranus

Niceness   - S- stands for Neptune

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.
