In 816,148 6 is in the thousandth. 148 is closer to zero than 1000. it rounds down. so rounding to the closest thousandth gets 816,000.
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.
