Answer:
Step-by-step explanation:
Given two parametric equations
and
, the first derivative can be found using the following equation:

In this problem,
and
. Finding the derivative of each of these functions with respect to
gives us the following:


Because
, that means the function is a vertical line and has an infinite first derivative.
Given,
Side = 7 cm
We know that,
Volume of a cube = side³
So, volume of Harry's cube
= (7 cm)³
= 343 cm³
Answer:
this is too old
