hmmm in short, the sign is like an opening with a corner > or <, and the value where the opening is, is the greater one, the value towards the corner, is the lesser one.
a > b <--- a is greater than b
b < a <--- a is greater than b
a ⩾ b <-- a is greater than or equals to b
b ⩽ a <--- a is greater than or equals to b
then again, you can also read it as
a > b <--- b is lesser than a.
b < a <--- b is lesser than a.
Circumference formula is C= 2 * pi * r
C=188.5 (pi 60)
ANSWER
EXPLANATION
The given equation is:
We integrate with respect to t to get,
The initial condition is y(0)=20
We apply the initial condition to get,
This implies that;
Or
In this big ol' word problem, this is just an instance of basic multiplication/division.
If it takes it 1 hour for 3 meters...
12 ÷ 3 = 4.
It would take 4 hours for the water level to change to 12 meters.
