Hey this is one question ive been struggling with in calc, if anyone could help that would be great thanks

Use a linear approximation to estimate the number sqrt(9.05)

A particle is moving along the curve y=sqrt(x). As the particle passes through the point (4,2), it's x-coordinate increases at a rate of 3cm/s. How fast is the distance from the particle to the origin...
