Answer:
m = - 2
Step-by-step explanation:
First coordinate : ( -2 , 9 )
Second coordinate : ( 1 , 3 )
Formulae : m=(y2-y1)/(x2-x1)
Substituting,
m = ( 3 - 9 ) / ( 1 + 2 )
m = - 6 / 3
m = - 2

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
