Homework Statement find dy/dx if x=1/1 + t and y = t2/1 + t Homework Equations dy/dx = (dy/dt) / (dx/dt) The Attempt at a Solution dx/dt = 1 * (1 + t )^-1 dx/dt = -1/ (1 +t)^2 dy/dt = t^2 * (1 +t)^-1 dy/dt = -2t/(1+ t)^2 therfore dy/dx = -2t/(1 + t)^2 / -1/(1 +...

Need help A system contains two components A & B. The system will function so long as either A or B functions. The probability that A functions is 0.95, the probability that B functions is 0.90, & the probability both function is 0.88. What is the probability that the system functions.
