Triangle Inequality Theorem The sum of the lengths of any two sides of a triangle is greater than the length of the third side. Third Side Rule The length of any one side of a triangle must be less than the sum of the other two sides, and greater than the difference between the other two sides. Slope Formula m = (y2 - y1) / (x2 - x1) Point Sloe Equation (y-y1) = m(x-x1) Slope-Intercept Form y=mx+b, where m is the slope and b is the y-intercept of the line. Special Right Triangles 45-45-90 triangle sides = x and x & hypotenuse = square root of 2 times x 30-60-90 triangle sides = x and square root of 3 times x & hypotenuse = 2x Meters in a foot 1m = 3.28 ft Percent Change Formula Percent Change =(final value−initial value)/initial value×100 Precedent Model. The prefix pre- means "before" the word root cede means "to go" and the suffix -ent means "something that" so it is an event or action that comes before another even or action. A model comes first and is used as a plan to make something else. Innocuous Bland. Means "harmless or inoffensive." For example this kind of substance is not harmful. Equivocate Be evasive.

For example, good waiters and waitresses: they care about keeping their customers happy. Aptitude Capacity to learn. means "natural ability or tendency."

The word root jeu or jocks means "play, game, or joke" and the word root partir means "to divide." A divide game is a game of chance that involves great risk, so to be in danger (of losing). Volume of a Cylinder V=πr²h Combustion Reaction a chemical reaction that occurs when a substance reacts with oxygen, releasing energy in the form of heat and light. A hydrocarbon reacts with O2 to produce CO2 and H2O Friction A force that opposes motion between two surfaces that are in contact Isotopes Atoms of the same element that have the same number of protons but different numbers of neutrons Outer Core of Earth Primarily made up of iron and nickel, is composed of a very hot liquid that flows around the center Which planet or its closest to the Earth? Venus Characteristics of a mineral Naturally occurring, solids, have a crystalline structure, have a single chemical compound Law of Sines a/sinA = b/sinB = c/sinC Quarts in Gallon 4 quarts = 1 gallon Tepid Mild. Lukewarm, unenthusiastic, or subdued. Appropriate Hijack. As a verb it is To take over, claim, or hijack a thing as one's own for example ideas. Indelible Permanent. Cannot be removed or forgotten. Passive Unassertive. This demeanor would be compliant, unassertive, or without effort. Belligerent Antagonistic. Unyielding, confrontational, combative. Pythagorean Theorem a²+b²=c² Surface Area of Cylinder 2πrh+2πr² pertroleum products Kerosene, unleaded gas, diesel fuel, sulfur covalent bond A chemical bond that involves sharing a pair of electrons between atoms in a molecule. Also called molecular bond. Halogens most reactive group of nonmetals Momentum the quantity of motion of a moving body, measured as a product of its mass and velocity. Mass Measure of an objects resistance to acceleration when a net force is applied. Radioactive isotopes are used for... To identify structural defects, to diagnose disease, to treat cancer, as a source of electricity.
