< We know that the rope is 3 pieces long. To make this into an equation, let's just write x + y + z = 150.
Assuming "y" is our second piece, we can tell y = 2x, because it is two times the size of the first piece, which is "x". We also know "z" (our third piece): z = 30.
We can try inputting all the things we know now. x + (2x) + 30 = 150. From here, we can find that x = 40. Since y is our second piece, y = 2x, so 2 x (40) = 80. The second piece would be 80 feet long. >

Answer:
The revenue function
R(x) = - 2x² +490x +2500
Step-by-step explanation:
<u><em>Explanation:-</em></u>
The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x
The price p in dollars that the company can charge for the product is given by p(x) = x + 5
Revenue = price × demand
Revenue = p(x) × d(x)
Revenue = (x+5) ×(500-2x)
Revenue = x(500-2x)+5(500-2x)
Revenue = 500x - 2x² + 2500- 10x
Revenue = - 2x² +490x +2500
