Answer:
8
Step-by-step explanation:
RT=10 it is on number A
XY=18 it is on number B
YZ=12 it is on number C
So, I think that no D 8 is in last so that is the answer.
Answer:
Step-by-step explanation:
Given that at time t, the position of a body moving along the s-axis is sequalsnegative t cubed plus 15 t squared minus 72 t m
i.e. 
Velocity is nothing but s'(t) = derivative of s
and acceleration is s"(t) = derivative of v(t)

a) v(t) =0 when t = 4 or 6
b) 
a(t) =0 when t =5
c) Distance travelled by the body from 0 to 5 would be

i.e. 110 miles (distance cannot be negative)
