<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:
Graphs represent the mathematical connections or interrelationships between the different set of the data whereas the charts represent the diagrams where one can find the depicted information or the data. As mentioned earlier all type of graphs are charts, but on the flip side, not all charts are graphs.
Step-by-step explanation:
I got this from the site called graphs vs charts i hope that is helps
Well first, we have to find the y intercept. So plug in your coordinates.
-2 = 4 (3) + b
Simplify
-2 = 12 + b
now, let's put like terms together.
-14 = b
b= -14
Hope I could help!
1 kg = 1000 g
1 cg = (1/100) g
2.4 kg
2.4 * 1000 g
2400 g
2400/100 cg
24 cg
Answer:
-1
Step-by-step explanation:
The y-intercept can be found when x=0, so find f(x) when x=0. So the first step is to evaluate (2/3)^0, which is 1. According to the equation this is multiplied by -1, so the y-intercept is -1. You can also use a graphing calculator (or Desmos) so you can see a physical representation of it. Hope this helps! :)
