Colons can be used to separate 2 full sentences. Unlike a semicolon, a colon can or cannot be for 2 full sentences. Colons are commonly used for lists, definitions, and explanations. These sentences are properly punctuated. He achieved great feats: finishing college at eighteen, learning new topics, and making many friends. The ACT is a standardized test:[…]

Line n passes through (12,4) and (-6,10). Line s is perpendicular to line n and passes through (-3,9). Find the equation of line n.
Both the SAT & ACT Math sections involve the manipulation of equations and solving linear systems. Percent change formula [(new-old)/old]*100 When you raise an exponent to another power you multiply the 2 exponents When you multiply the bases you add the exponents — For linear functions start with slope. Solve for slope then set up[…]
Mastery of parabolas is essential for math on the ACT and SAT. For parabolas vertex is (h,k) y=a(x-h)^2 + k y=ax^2+bx+c form vertex x= -b/2a
Definitions for Chemistry Labs: – Solution = liquid mixture – Titrant = solution of a known concentration. Use a burette to put the titrant into a solution (in a beaker). – Solute = minor component that is uniformly distributed in the solvent – Solvent = major component that contains the solute – Precipitate = insoluble[…]
A circuit is a complete path that electricity flows through. There is a source of electricity (battery). Conductors are the materials that allow electric current to pass through them easily. Conductors like the positive and negative ends of a battery. In a closed circuit, the electricity flows without any interruptions. Ohm’s Law: Voltage (V); Current[…]
Types of Electronic Bonds 1. Covalent bonds – 2 or more elements share electrons (ex: H2O) 2. Ionic bonds – strongest bonding. One element takes an electron from another molecule (ex: NaCl) 3. Hydrogen bonds – weakest form of bonding. Hydrogen atom interacts with an electronegative atom like nitrogen, oxygen, or fluorine
