Answer:
-35-18x
Step-by-step explanation:
just calculate the difference
-35-20x+2x
-35-18x
It will be
(4,000) divided by (the value of 4 in the number you left out).
As the fellow above said, the particle does make a U-turn at the vertex, and we can find that out by getting the derivative of s(t) and zeroing it out to get the point of the horizontal tangent.
Bearing in mind that ds/dt is really v(t) or the velocity equation, so when we zero out the ds/dt, is the same as saying the velocity went to 0, since it got zeroed out, and then the particle goes over the vertex and changes direction.

the negative acceleration value, simply means a decreasing rate of change, so, it means the particle is slowing down and possibly coming to a stop before changing direction again.
Answer: Suppose we have four ants, initially at rest, at the four corners of a square centered at the origin. They start walking clockwise, each ant walking directly toward the one in front of him. Suppose also that each ant walks with unit velocity, derive a differential equation that describes the trajectories.
Answer:
Step-by-step explanation:
i say 3 :I
cuz theres 3 dots spreed out and it said to connect the dots by starting off one and connect the others so i think its 3
