You need to prepare for your meeting with the BeeSwaks executives by writing and graphing functions so thatyou can compare the volumes and resulting production costs of each candle. The BeeSwaks executives want tosee detailed support for the calculations done by their production staff, so you should come armed with labeledgraphs and worked-out equations to support them. 1) Use your equations from Lesson 1 for the Brick candle and the Egyptian candle to create a graph of twopolynomial functions so that you can compare volumes for different values of x. Compare the volumes. ( my equations, figured out in Lesson 1 below) Brick candle equation- V= x^3-x^2 Eqyptian candle equation- V= 7x^2 2) Use the graph from Question 1 to identify where the volumes are equal. Confirm this value by writing andsolving an equation that describes the difference between the volumes of the candle types. 3) . The same wax will be used to make each candle, and it costs 3/4 of 1¢ per cubic centimeter. Write…

Please answer with a neat presentation, so that it's easy to read. Also, if you can show your work so that I can see how to do the current and future problems like this. Thank you.
The Ruler Postulate suggests that there are many ways to assign coordinates to a line. The Fahrenheit and Celsius temperature scales on a thermometer indicate two such ways of assigning coordinates. A Fahrenheit temperature of 32° corresponds to a Celsius temperature of 0°. The formula, or rule, for converting a Fahrenheit temperature F into a Celsius temperature C is C = -(F 32). a.What Celsius temperatures correspond to Fahrenheit tem- peratures of 212° and 98.6°? b.Solve the equation above for F to obtain a rule for converting Celsius temperamrcs to Fahrenheit temperatures. c.What Fahrenheit temperatures correspond to Celsius tem- peratures of - 40° and 2000°?
