1. Gradient y2-y1/x2-x1 2. Length of a line sqrt((x2-x1)^2+(y2-y1)^2) 3. Midpoint (x1+x2/2, y1+y2/2) 4. How do you know if two lines are perpendic- ular? When you multiply the gra- dients together they should equal -1. The general rule is perpendicular = -1/m. Or you could use Pythagoras to show there is a right angle 5. How do you know if two lines are parallel? The gradients should be the same 6. What should you always remember when finding the square roots? The answer cou...

Given: line DE is the perpendicular bisector of line HJ Which statement is true? Correct Answer Line DE (weird sign) Line HJ Given:Line DE is the perpendicular bisector of line HJ Correct Answer FALSE Given: Line CD is the perpendicular bisector of line IK Which statement is true? Correct Answer IJ is congruent to JK Find the center of the circle that you can circumscribe about the triangle. Correct Answer (-1, -1) The point of concurrency of the angle bisectors of a triangle is ca...

Quadratic Formula Domain The set of possible inputs for a function. Range The set of possible outputs of a function. Discriminant b² - 4ac > 0 then two distinct real roots. b² - 4ac = 0 then one repeated real root. b² - 4ac < 0 then a quadratic function has no real roots. Types of Lines for Regions If y < f(x) or y > f(x) then the curve y = f(x) is not included in the region, and is represented by a dotted line. If y ≤ f(x) or y ≥ f(x) ...

Aquifer - answer-underground geologic unit that is saturated with water which contains sufficient permeability to yield the water to wells. Unconfined aquifer - answer-Water surface is at atmospheric pressures. Confined aquifer - answer-Aquifer that is confined by an impermeable material, such as clay or shale, resulting in the aquifer being under pressure. Permeability - answer-A measure of the ability to transmit fluids based on the material within the aquifer. Transmissivity - ans...

1.1 Permutation Groups Suppose a set G is closed under an operation ∗. That is, suppose a ∗ b ∈ G for all a, b ∈ G. Then ∗ is called a binary operation on G. We will use the notation (G, ∗) to represent the set G with this operation. Suppose (G, ∗) also satisfies the following three properties. 1. (a ∗ b) ∗ c = a ∗ (b ∗ c) for all a, b, c ∈ G. 2. There exists an identity element e ∈ G for which e ∗ a = a ∗ e = a for all a ∈ G. 3. For each a ∈ G, there ex...
