How aerospace engineers use the quadratic equation?
The quadratic equation is used to find the intercepts of a function (F(x)=x^(2*n), n being an even number) along its primary axis (typically the x axis). Many equations follow this form. The information given by the quadratic equation depends on what your function is pertaining to. If say you have a velocity vs time graph, when the function crosses the xaxis your particle has changed from a positive velocity to a negative velocity. This information can be useful to determine the accompanying behavior of your position. The quadratic equation is simply a tool to find intercepts of a function.

Slope Formula-Formula used to find the rate of change of a line. (Show on board) 135. Slope-Intercept Form-A linear equation written in the form y=mx+b where m is the slope and b is the y-intercept of the equation's graph. (show on board) 136. Solution-A number or ordered pair of numbers that make an equation or an inequality true 137. Solve-To find the value of the variable(s) of an equation or inequality. 138. Sphere-A solid formed by all points in space that are the same distance from a fixed point called the center. 139. Square Root-Also called a radical. When trying to fine what number squared gives you the number inside this symbol. (show symbol on board) 140. Stem-and-Leaf Plots-A data display that helps you see how data values are distributed. Each data value is separated into the last digit and the remaining digits. 141. Straight Angle-An angle whose measure is exactly 180 degrees. 142. Substitution-A property that allows you to replace terms of equal value for one another. Example: putting 4 in for x. 143. Sum-The result when two or more numbers are added. 144. Supplementary Angles-Two angles whose measures have a sum of 180 degrees. 145. Surface Area-The sum of the areas of the outside surfaces of a solid. 146. Terminating Decimal-A decimal that has a final digit that stops and does not repeat. 147. Theoretical Probability-The probability of an event when all outcomes are equally likely. What is supposed to happen when playing the game. 148. Transformation-A movement of a figure in a plane that is done by a reflection, rotation, translation, or dilation. 149. Translation-A transformation that slides each point of a figure the same distance in the same direction. 150. Trapezoid-A quadrilateral with exactly one pair of opposite side parallel. 151. Trinomial-A polynomial with three terms. 152. Unit Rate-A rate that has a denominator of 1 unit. 153. Upper Quartile (Quartile 3)-The median of the upper half of an ordered data set 154. Variable-A letter that is used to represent one or more numbers. 155. Vertex-The common endpoint of the two rays that form an angle. Where the endpoints of polygons meet. 156. Vertical Angles-A pair of opposite angles formed when two lines meet at a common point. 157. Vertical-A line or direction that is parallel to the y-axis and goes from top to bottom/up and down (north to south) 158. Volume-The amount of space a solid contains in terms of cubic units. Amount of space inside the object. 159. Whole Numbers-The set of numbers 0,1,2,3….. Also called the Natural numbers including 0. 160. X-Axis-The horizontal axis in a coordinate plane. 161. X-Coordinate-The first number in an ordered pair representing a point in a coordinate plane. 162. X-Intercept-The x-coordinate of a point where the graph crosses the xaxis when y=0. 163. Y-Axis-The vertical axis in a coordinate plane.
