Answer:
no
Step-by-step explanation:
You can simplify them both.
3x+12=12 and 3x + 3 =4
make them both so they equal 0
3x=0 and 3x-1=0
no, theyre not equal since when they both equal 0, they are not the same equation
When you have a negative variable you can divide each side by the - but remember to flip your sign...
so the first one is correct
I believe it is not a tight trying because as I was taught, A+B=C & C-A=B which does not work out in this case.
We are given with the following given
dV/dt = 35 m3/min
h = (3/2)D
What is asked is
dr/dt at t = 7 min
The volume of a cone is
V = (1/3)πr²h
From the given
h = (3/2)D
since D = 2r
h = 3r
Subsituting
V = πr³
At t = 7 min, the volume is
V = 35(7)
V = 245
and the radius is
245 = πr³
r = 4.27
Differentiating the volume
dV/dt = 3πr² dr/dt
From the given
dV/dt = 35
Subsituting
35 = 3πr² dr/dt
So,
dr/dt = 0.20 m/s
and
dh/dt = 0.60 m/s
