<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:
it is C)15x - 175 < 10
Step-by-step explanation:
Answer:
= 6/5 or 1 1/5 or 1.20
Step-by-step explanation:
= 1/2(12÷3)3/5
= 1/2 (4) 3/5
= 2 x 3/5
= 6/5

So we know that point-slope form is as follows:
The points (
and 
correspond to the point given and m is representing the slope. So we plug in what the question gives us:
<------ Point-slope form
Now we can take this form and simplify to give us the slop-intercept form:
<----- Slope-intercept form
Jar 1 : 16 red, 4 blue....total = 20
P(blue) = 4/20 reduces to 1/5
jar 2 : 75 white,25 blue...total = 100
P(blue) = 25/100 reduces to 1/4
P(blue,blue) = 1/5 * 1/4 = 1/20 or 0.05 or 5%
