T(x, y) = (x - 5, y - 6) since you are trying to translate back to the original point and therefor should do the reverse set of translations

At a certain point in time, each dimension of a cube of ice is 30 cm and is decreasing at the rate of 2 cm/hr. How fast is the i

Marta_Voda [28]

Recall that for a cube, all dimensions, length, width and height, are the same in value.

so, if say length = width = height = x, then the volume of the cube is V = x³, therefore

$\bf V=x^3\implies \cfrac{dV}{dt}=\stackrel{chain~rule}{3x^2\cfrac{dx}{dt}}\quad 
\begin{cases}
x=30\\
\frac{dx}{dt}=\stackrel{cm/hr}{2}
\end{cases}\implies \cfrac{dV}{dt}=3(30)^2(2)
\\\\\\
\cfrac{dV}{dt}=5400$
