Asteel beam can be cut to different lengths for a project. assuming the weight of a steel beam is proportional to its length, what information would you need to know to write an equation that represents this relationship? (10 ! )

the weight of the steel beam and steel beam length

let y be weight and x be length of it

y=ax

where a is the constant

we can find it if we have two sets of values of y and x

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
