Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.

Describe the 2 algebraic methods you can use to find the zeros of the function f(t)=-16t^2+400.

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
