<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

Mr. Stack and Coach Pugh are racing down the highway. Coach Pugh is going five miles more an hour than twice Mr. Stack's speed.

ahrayia [7]

Answer:

Step-by-step explanation:

2(Mr stack's speed) = Coach Pugh's speed - 5mph

Mr stack's speed = (105mph - 5mph)/2

Mr stack's speed = 100mph/2

Mr stack's speed = 50mph

Liliana wants to write an equivalent expression for n + 3 minus 5 n + 6. Which of her attempts uses the algebraic properties cor

torisob [31]

Answer:

Option A.

Step-by-step explanation:

The given equation is

$n+3-5n+6$

Liliana wants to write an equivalent expression.

It can be written as

$n+(3-5n)+6$

Using commutative property, we get

$n-5n+3+6$ $[\because A+B=B+A]$

Using associative property, we get

$(n-5n)+(3+6)$ $[\because A+(B+C)=(A+B)+C]$

Using distributive property, we get

$(1-5)n+(3+6)$ $[\because An+Bn=(A+B)n]$

Using addition property, we get

$-4n+9$

Therefore, the correct option is A.
