Precal homework I need help

    precal homework I need help plz

    1. The problem statement, all variables and given/known data



    2. Relevant equations


    1.T(t)=4t/(t^2+1)+98.6
    find T,t

    2.P(x)=1500/(x^2-6x+10)

    3. The attempt at a solution

    1.4t/t^2+1=98.6
    sub t=2
    4t/2(2)+1=98.6
    T=8/5+98.6
    1.6+98.2=100.2
    not sure how to find t

    I dont know how to even attempt question 2

    I'm not even sure what you are supposed to be doing either. Why don't you supply a complete problem statement?

    For one thing, this makes no sense. There t can be anything with a corresponding value for T.

    This is a function. What are you supposed to do with it?

    This is true if the original equation were 4t/(t^2+1)+98.6= 197.2 or if you meant to write
    T(t)= 4t/(t^2+ 1)+ 98.6. But you did not write either of those.

    Why?

    ??? You just declared that it was "2"! I have no idea what you are even trying to do.

    That's probably because there is NO "question 2". An equation is not a question. Go back and read the problems again and find out exactly what you are asked to do. Do not just look at the equations, read the instructions. Once again, an equation is not a question nor a problem. You have to be asked a question about the equation or told to do something with it.
