Answer:
x = 2.
Step-by-step explanation:
I am taking this to mean
2^3 * x^3 = (2 + x)^3
8x^3 = (2 + x)(4 + 4x + x^2)
8x^3 = 8 + 8x + 2x^2 + 4x + 4x^2 + x^3
7x^3 - 6x^2 - 12x - 8 = 0
7(2)^3 - 6(2)^2 - 12(2) - 8
= 56 - 24 - 24 - 8 = 0
x = 2.
This is the only real root.
Answer:
the pile has a height H = 15.09 ft
Step-by-step explanation:
The volume of a cone V is
V= 1/3*π*H*R²
where H= height , R=radius
if the diameter D=2*R is 3 times its height
D=3*H → 2*R=3*H → R=3/2*H
then
V= 1/3*π*H*R² = 1/3*π*H*(3/2*H)² = 1/3*π*H*9/4*H² = 1/12*π*H³
V= 1/12*π*H³
if the volume is V=900 ft³ , then solving for H
V= 1/12*π*H³
H = ∛(12*V/π) = ∛(12*900 ft³/π) = 15.09 ft
H = 15.09 ft
then the pile has a height H = 15.09 ft
Amy's weight = 55 kg also Amy's velocity = 3 m/sec. And Jenny's weight = 40 kg Jenny's velocity = -5 m/sec. their final mass = 55+40 = 95 kg is their final velocity that we want to find out.
Ect. but in conclusion the answer is 7/19 m/sec.
I hope this is correct >w< if it's not I am really sorry I mist up.
I=P*R*T
I - Interest
P - Principal (how much you invest) - $1025
Rate - Interest rate - 6.5% = . 065
T - Time - 5 years
I = 1025*.065*5
The interest is $333.13 (333.125 rounded)
The ending balance is interest+principal
$333.13+$1025=$1358.13
Ending Balance = $1,358.13
