First I would like to say thank you all who have helped myself and others on here. I was able to get through Exam 1 with a 78% which I will take considering math is my weakest subject and I'm taking Calc I online.
This week it is Related Rates which I'm taking nice and slow. With that, here is problem number 1.
1) A particle on the x-axis is moving to the right at 2 units per second. At a certain instant it is at the point (5,0). How rapidly is the distance between the particle and the point (0,9) on the y-axis changing at that point?
I drew my X-Y graph and marked points (0,9) and (5,0). I labeled X= distance and Y=time. The problem gives me dx/dt=2 units/sec.
The basic relationship looks like it should be a right triangle/Pythagorean Theorem.
So that is about where I am at because I know the next step is to sub the information into the equation but it's suppose to use implicit differentiation which I thought requires an unknown Y value...but it looks like I know the sides of the triangle A ^2+ B^2 but need C^2.
What am I missing?
