A particle is moving along the curve y=22x+1−−−−−√y=22x+1. As the particle passes through the point (4,6)(4,6), its xx-coordinat
e increases at a rate of 44 units per second. Find the rate of change of the distance from the particle to the origin at this instant?
1 answer:
Answer:
the rate of change of the distance from the particle to the origin at this instant = 3.33unit/secs
Step-by-step explanation:
The approach to solve the question involves , concept of rate of change in differentiation, implicit differentiation and appropriate substitution were made to get the rate of change of distance.
The steps are as shown in the attached file.
