Each month, College of w88 online sports betting alumni have the opportunity to test their skills and solve a current w88 online sports betting student exam question. These questions are posed in the monthly College of w88 online sports betting newsletter, Discovery Monthly. The very first w88 online sports betting Question of the Month was featured in the 2022 alumni magazine Discovery. The question, provided by mathematics professor Charlie Nazemian, was pulled from a Math 181 exam.

A particle is moving along the curve whose equation is: xy3/1+y2= 8/5
Assume that the x-coordinate is increasing at the rate of 6 feet/sec when the particle is at the point (1, 2). At what rate is y-coordinate changing at that instant, and is it rising or falling?
Solution
This is a related rate problem.
- Given dx/dt = 6 ft/sec, when x =1 and y = 2.
- We take implicit differentiation from both of: (xy3)/(1+y2) = 8/5
- 5xy3 = 8 + 8y2
- 5[(dx/dt)y3 + 3xy2(dy/dt)] = 0 + 16y(dy/dt)
- After simplifications and substitutions for dx/dt = 6 , x = 1 and y = 2, we can solve for dy/dt.
- Answer:dy/dt = -60/7 ft/sec, the negative answer means that it is falling at that moment.
