## Explain the positioning of the roots of the polynomial on its graph with respect to the discriminant and the sign of the discriminant.

The solutions of the quadratic equation Ax^2+Bx+C=0 are called roots and are given by a famous equation called the Quadratic Formula . In the quadratic formula, the terms B^2-4AC underneath the radical have a special name: the Discriminant .
Discuss the relationship between the discriminant of a quadratic polynomial and the quantity of real roots it possesses. Explain the positioning of the roots of the polynomial on its graph with respect to the discriminant and the sign of the discriminant.

## For this math-based discussion, follow the steps below.

Linear Extrapolation
Last week you were introduced to graphing linear functions. One common use of linear equations is linear extrapolation, where you take real data to make a linear equation, and then use it to make predictions.
For this math-based discussion, follow the steps below. Type all math in the discussion using the Blackboard Math Editor. Make sure you are giving details and explaining each step in your post.
Research the sales or revenue for a company and write 2 ordered pairs in the form (year, dollars).
Find the slope between those two points and interpret what it means in context for the company you chose.
Use Point-Slope Form to write the equation of the line between these points.
Use your equation to predict future sales or revenue, and discuss whether you think your prediction will be accurate and why/why not

## All mathematical steps must be formatted using the equation editor.

Your donut shop has perfected a method for the perfect glazed icing by slowly mixing whole milk to confectioner’s sugar while exposed to low heat. Your mixing tank starts with 10 fluid ounces of milk and 10 ounces of sugar. You continue adding sugar at a rate of 10 ounces per minute and milk at 1 ounce per minute, as depicted by the two equations below:
﻿S equals 10 plus 10 t﻿
﻿M equals 10 plus 1 t﻿
Where S represents the number of ounces of sugar, M represents the ounces of milk, and t represents the time in minutes. The ideal icing will have a ratio of 8 ounces of sugar per ounce of milk.
Assessment Instructions
Show and explain all steps in your responses to the following parts of the assignment. All mathematical steps must be formatted using the equation editor.
Part 1: Create a rational equation to represent the concentration (C) in ounces of sugar per ounce of milk.
Part 2: Find the domain of the concentration equation.
Part 3: Will we ever encounter a time where the rational equation is undefined? Explain your reasoning.
Part 4: Calculate the concentration after five minutes.
Part 5: How long does it take to reach a concentration of 8 ounces of sugar per ounce of milk?

## Analyze the statement made by the scarecrow.

In the 1939 movie The Wizard of Oz, upon being presented with a Th.D. (Doctor of Thinkology), the Scarecrow proudly exclaims, “The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side.” Analyze the statement made by the Scarecrow. Present your analysis and give a complete description of the triangles that satisfy the statement.
Find another example of math being used in:
Movies, television, popular culture, art, music and harmonics, scientific research papers, newspapers or magazine articles, nature and natural phenomena, voting, national security, manufacturing, logistics, transportation, healthcare, business, economics, or some noteworthy or pivotal historical moment.
Research and explain whether or not the math was used correctly.
