Answer:
37.5%
Step-by-step explanation:
3/8=37.5%
Hope this helps! :)
<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:
c = 2
Step-by-step explanation:
6 = 6c-6
+6 +6
12 = 6c
12 / 6 = 2
If x is the number of miles to g then
x <= 26 .2 - 10
x <= 16.2
