Answer:
:)
Step-by-step explanation:
I have no idea in the slightest
<span>the particle's initial position is at t=0, x = 0 - 0 + 4 = 4m
velocity is rate of change of displacement = dx/dt = d(t^3 - 9t^2 +4)/dt
= 3t^2 - 18t
acceleration is rate of change of velocity = d(3t^2 -18t)/dt
= 6t - 18
</span><span>the particle is stationary when velocity = 0, so 3t^2 - 18t =0
</span>3t*(t - 6) = 0
t = 0 or t = 6s
acceleration = 6t - 18 = 0
t = 3s
at t = 3s, velocity = 3(3^2) -18*3 = -27m/s
displacement = 3^3 - 9*3^2 +4 = -50m
Answer:
The P-Value is 0.009999
Step-by-step explanation:
we have 5 categories
df=5-1=4
With alpha = 1%, the critical Chi-square value is 13.277
The P-value is define as the shows the degree of inconsistency of our data set with hypothesis.
using a significant level of 0.01,
The P-Value is 0.009999. The result is significant at p <0.01
