Let h=height of water
Let r=radius of water surface
r/h=16/8 =2, so r=2h.
The volume of water is:
v=(1/3)×π×r²×h
=(1/3)×π×(2h)²×h
=4/3πh³
dv/dh=4πh^2
By chain rule:
dv/dt=dv/dh×dh/dt
but
dv/dt=4
thus:
4=(4πh)×dh/dt
dh/dt=4/(4πh²)
when h=6cm we have:
dh/dt=4/(4π6²)
=0.00884 cm³/min
Answer:
x>9
Step-by-step explanation:
4/9 divided by 2/3 divided by 5/6 = 4/5
when you divided by two fractions, you can flip the denominator and numerator and then mutiply
Answer:
Option 1
Step-by-step explanation:
f(x) = Asin(Bx) + C
C = 4
B = 4
A = 8-4 = 4
f(x) = 4sin(4x) + 4
X>32<18
a number is less than <18 X is greater >32
