Aparticle travels along the x-axis such that its position at time t is given by the function x(t)=2t^2+t. what is the average speed of this particle over the interval 2 ≤ t ≤ 10?

a) 4

b) 25

c) 32

d) 200

. you!

Solve for x i'll try to attach the files bc it's not letting me for some reason

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)

Ming says that 0.24 > 1/4 because 0.24= 2/4. which best explains mings error
