The scatter plot shows the length of a spring (in inches) when a stretch force (in pounds) is applied. The equation represents t
he linear model for this data.
y = 0.73x + 1
What does the number 0.73 in the equation mean in this context?
a The spring has no stretch when a force of 0.73 pound is applied.
b The spring will stretch 0.73 inch for every pound of force applied.
c The spring stretches a distance of 1 inch when a force of 0.73 pound is applied.
d The spring stretches at a rate of 0.73 pound per inch.
e The spring has a length of 0.73 inch when no force is applied.
y = 0.73x + 1
What does the number 0.73 in the equation mean in this context?

Answer:
The value is
Step-by-step explanation:
From the question we are told that
The area of the rectangular pen is
The cost of material used to make one side is
The cost of material used to make the other sides is
Now , the fence to be build around the rectangular pen has four sides, the first opposite sides are equal, let assume each of the to be x yard and the other opposite sides are also equal as well let assume of the to be y yard
So the cost is mathematically represented as
=>
=>
Now the area of the fence is mathematically represented as
=>
=>
=>
Now differentiating
At minimum
So
Now substituting for x in the equation above to obtain minimum cost
