Guys can you help me with this????
A trough L metres long has a cross-section in the shape of an isosceles triangle with base length 2a metres and height b metres. Water leaks from the trough at a constant rate of c m^3/min. Find the rate at which the water level is falling when the depth of...
Yusss, Thank you so much, I thought we can use 1600 as the initial value XD.
I got another question from the same kind.
