Answer:
The constant of proportionality for the group of boxes is: 25
Step-by-step explanation:
Proportion means that change in one quantity causes change in other quantity. Direct variation means that increase in one quantity causes increase in the other quantity.
Let l be the length and v be the volume
Then according to given statement
V∝l
Removing the proportionality symbol introduces a constant in the equation
![V = kl](https://tex.z-dn.net/?f=V%20%3D%20kl)
Putting V = 325 and l = 13
![325 =k(13)\\k = \frac{325}{13}\\k = 25](https://tex.z-dn.net/?f=325%20%3Dk%2813%29%5C%5Ck%20%3D%20%5Cfrac%7B325%7D%7B13%7D%5C%5Ck%20%3D%2025)
Hence,
The constant of proportionality for the group of boxes is: 25
5x-3x^2/2x^4 =x(5-3x) / 2x.(x^3), simplified by x, we have <span>5-3x/2x^3, (x≠0)
</span>so the answer is <span>C.5-3x/2x^3, (x≠0)</span>
