when a cylindrical tank is filled with water at a rate of 3 cubic meters per minute what does dh/dt equal

meters per minute

Step-by-step explanation:

Volume of a cylinder is given by the formula,

V = πr²h

Where r = radius of the cylindrical tank

h = height of the tank

Water is filling in this tank = 3 cubic meters per second

Derivative of volume will show the change in volume of the water in the tank.

By putting in the expression,

[Since 'r' is a constant]

Therefore, rate of increase in height of the water level will be represented by,

meters per minute

idk do it yourself or ask somebody idk stop going online asking for

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
