A factory that makes statuettes is trying to maximize its income. Their two primary products are the Liberty and Colossus statuettes. Each Liberty requires 36 minutes of machine time to rough cut the shape and 60 minutes of artist time to finish the details. The Colossus requires 48 minutes on the machines and 30 minutes with the artist's hand. The factory is limited each day to 432 minutes of machine time and 600 minutes of artist time. Both use 22 kilograms of stone, and the factory has 242 kilograms of stone available per day. If each Liberty brings in a profit of ninety-six dollars, and each Colossus brings in ninety-one dollars, how many statuettes of each type should the factory make each day?

What are the most important things to consider when identifying a model to fit a set of data? Be sure to list as many characteristics as you can, but don't be afraid to share any thoughts, ideas, or uncertainties you may have about a particular model. If you're unsure about something, just ask some clarifying questions to help you get a better idea of what the model's key features are. Your post must have a minimum of 5 sentences.

Descartes' Rule of signs Use Descartes' Rule positive and how of Signs to determine how many negative real zeros of the polynomial can have. Then determine the possible total number of real zeros.

P(x) = x^3 - x^2 - x - 3

P(x) = 2x^3 - x^2 + 4x -7

P(x) = 2x^6 + 5x^4 - x^3 -5x -1

P(x) = x^4 + x^3 + x^2 + x + 12

P(x) = x^5 + 4x^3 - x^2 + 6x

P(x) = x^8 - x^5 + x^4 - x^3 + x^2 - x + 1
