Answer:
6+6=12 cm
4+4=8 cm
6+6= 12 cm
Add all together and it equals 32
Step-by-step explanation:
<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
The answer is 20 y=9 times that and y= 9 times that also u subtract and then u get 20.
<h2>$650</h2>
Step-by-step explanation:
The principal amount recieves a simple interest every year. The simple interest rate is given as 
.
It is given that the total amount after 20 years is $812.50
Here 
is the principal amount, 
is the interest rate, 
is the time period.
∴ Samson had $650 when he opened the account.
