If we are concern only with the velocity of the particle along the x-axis, then, this implies that the velocity along the y-axis is hypothetically = 0ms^-1
∴ v = (vx=0,vy)
vy = 0ms^-1
vy = (dr/dt)y = 0ms^-1
ry→ = (2ct^2 -dt^3)j
dr/dt = 4ct - 3dt^2
4ct - 3dt^2 = 0
4c = 3dt
t = 4c/3d
$90 because you take the discounted price then divide it by .40 (40%)
Answer:
I believe your answer is 264. The bike cost $264.
Step-by-step explanation:
C. 4 and 6. 6*4=24, 4/6=2/3 (width is 2/3 the length).
C. can be used to solve it
other way is: p/100 *80 = 23
0.8p = 23
p = 23/0.8 = 28.75
