Homework Help Overview

The discussion revolves around solving for the variable B in a mathematical equation involving A. The original poster expresses difficulty in matching their solution with a provided answer from a textbook.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants question the definition of variable A and the necessity of having two equations to solve for two variables. There is also a suggestion to reconsider the interpretation of the textbook answer.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem and questioning the assumptions made about the variables involved. Some guidance has been offered regarding manipulating the equation, but no consensus has been reached.

Contextual Notes

There is a mention of a parent equation that may provide additional context, but it is unclear how it relates to the original equation. The original poster has only provided one equation, which may limit the ability to solve for B definitively.

HI, i can't solve this equation. I am solving for B the answer in the book does not match mine. PLZ help.


(1.5999A)^2= B^2 + A^2

the answer in the book is 1.247

What is A? You need two equations to solve for two variables.
 
thats all i have. the parent equation was

.0251A=.0157sqrtB^2 + A^2
 
Are you absolutely sure the answer in the book isn't "1.247A"? :wink:

Anyway, just subtract A^2 from both sides and take a square root to get that answer.
