Answer in the attachment.
A is the correct answer 3 terms and a degree of 9:)
You do 27 divided by 90 27/90=0.3 and then move the decimal two places which would give you 30%
<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
<h2>
Answer:The graph of
is the graph of
compressed vertically.</h2>
Step-by-step explanation:
Given that 
and 
is always positive because 
is always positive.
is always positive because 
is always positive.
So,both are always positive.
So,there is no flipping over x-axis.
In ,the height of a point at 
is 
In ,the height of a point at is 
So,height of any point has less height in than
So,the graph of is the graph of compressed vertically.
