Homework Help Overview

The original poster presents two precalculus problems involving functions. The first function, T(t), relates temperature to time, while the second function, P(x), appears to be a rational function. The poster expresses uncertainty in both problems, particularly in determining the variable t for the first function and the nature of the second function.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants question the clarity of the problem statements and the original poster's approach to solving the equations. There is a request for a complete problem statement to better understand the tasks at hand. Some participants express confusion regarding the assumptions made about the variables and the lack of explicit questions associated with the equations.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the problem statements and the original poster's attempts. There is no consensus yet, as participants are exploring the implications of the equations and questioning the original poster's interpretations.

Contextual Notes

There is a noted lack of complete problem statements, which is affecting the ability to provide guidance. Participants emphasize the importance of understanding what is being asked in relation to the equations presented.

precal homework I need help please

Homework Statement





Homework Equations




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

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

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 don't 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?
 


Yes, please provide a complete statement of the problem.

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

2.P(x)=1500/(x^2-6x+10)
This is a function. What are you supposed to do with it?

The Attempt at a Solution



1.4t/t^2+1=98.6
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.

sub t=2
Why?

4t/2(2)+1=98.6
T=8/5+98.6
1.6+98.2=100.2
not sure how to find t
? You just declared that it was "2"! I have no idea what you are even trying to do.

I don't know how to even attempt question 2
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.
