To calculate the starting point of lane 2 for which the lengths of two lanes will be equal.
Answer to Problem 38E
Therefore the starting point of lane 2 is
Explanation of Solution
Given information:
The equation for lane 1is
The equation for lane 2 is
The starting point for the lane 1 is at the negative x -intercepts
Formula used:
If a smooth curve begins at
Calculation :
Consider the starting point of lane 2 be
Arrange the equation of lane 1 in standard form
Therefore end point of lane 2 is
Arrange the equation of lane 2 in standard form
Therefore end point of lane 2 is
Equation for the length of lane 1
Equation for the length of lane 2
Since these two lengths are equal
The value of abscissa at
Put the value in the equation of lane 2 to get the value of ordinate of
Therefore the starting point of lane 2 is
