Math 3 201: Circle Equations
Unit 2 covers an algebraic look at a topic called conic sections. These are the shapes that you can
make by intersecting a cone with a plane. The picture below shows the four shapes we are going to
be discussing in thi
Math 3 110: Two-variable System of Equations
The rest of the week we will be practicing solving systems of equations with two variables. I will guide
you through the first one, and then you can try some on your own.

Math 3 108: Matrix Inversion
Over the course of a year, a state trooper issued a total of 385 citations for warnings and speeding
tickets. Of these, there were 31 more warnings than speeding tickets. How many warnings and how
Math 3 107: Matrix Multiplication
Yesterday, we investigated the multiplication of a matrix with a real number (or scalar). But
what happens when we multiply two matrices?
To begin, we must understand an algebraic operation used in mathematics cal

Your flower garden is now entering its third year of existence, and thanks to your improved gardening
Math 3 103: Matrix Addition
Work individually on the following problem (#1 6), then compare your answers with your neighborhood.
Last year, you planted a flower garden in your front yard consisting of 5 rose bushes, 36 sunflowers, and
Math 3 101: Introduction to Matrices
Unit 1 is devoted to studying the use of matrices (the plural form of the word matrix). To begin, we
must understand that a matrix is a special type of array. Arrays are very important in todays world
Math 3 112: Three-variable System of Equations
Now, we will be moving on to larger systems of equations, and learning how to solve these systems
using our calculators. Remember, as long as we start with the matrix equation CV = R, we showed that

AN OKEFENOKEE FOOD WEB Learning Task:
Recent weather conditions have caused a dramatic increase in the insect population of the
Okefenokee Swamp area. The insects are annoying to people and animals and health officials
Math 3 121: Vertex-Edge Graphs
MM3A7. Students will understand and apply matrix representations of vertex-edge graphs.
A vertex-edge graph is a collection of points (vertices) and line segments (edges) arranged to
portray how information is connec
Math 3 119: Linear Programming
MM3A6. Students will solve linear programming problems in two variables.
Now that we understand the concepts of graphing inequalities, we can move forward to linear
programming. Linear programming is the process of m
Math 3 117: Graphing Systems of Inequalities
Yesterday, we learned how to graph linear inequalities. The general information we learned (whether
the boundary is dashed or solid, and whether to shade above or below the boundary) applies regardless
Math 3 116: Graphing Linear Inequalities
Weve been working a lot with systems of linear equations. Our solutions to these systems
represented the only pair of values that satisfied both of the equations in the system. For
example, remember our ini

Tonight, with the stress of Engsbergs quiz hanging over you, sleep comes slower than usual.
Eventually, after much tossing and turning, you fall into a fitful rest. When you awake, you are
startled to find yourself curled up on
Math 3 202: Completing the Square
Perfect square an integer that is the product of a different integer with itself. Example: 64 is a perfect
square because it is equal to 8 times 8.
We will need to understand the definition of a perfect square bec
Math 3 308: Solving Exponential Equations Part 1
One area we have not covered yet in our review of exponential functions is solving exponential
equations. Understanding how to solve exponential equations can help you later in life if you plan to

Math 3 301: Review of Exponential Properties
Weve spent the last month discussing polynomial functions, in which the variable was raised to an
exponent. In the next unit, we will start by reviewing exponential functions, where the variable is
