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:[…]
Growth Problems: For LINEAR GROWTH, y always changes by the same amount when x changes by the same amount. Example: Each successive year, $100 is added to the value of the account. For EXPONENTIAL GROWTH, y increases by more and more as x increases by the same amount. Examples: A stock doubles in value every[…]
Seminal = Found work/first important work of an author, painter, etc… Implicit = Not directly stated Tacit = Not directly stated Explicit = Directly stated Commission (v) = To authorize or give an order Commence = To begin Surly = Rude/unfriendly Abysmal = Terrible Empirical = Evidence based Heuristics = Guess and check, trial and[…]
– Water exists in 3 states: Solid/ice, liquid/drinking water, gas/water vapor. Melting point = freezing point. They both describe the same transition of matter – liquid to solid is freezing and solid to liquid is melting. Freezing point of water — 32 F and 0 C at 1 atm of pressure Boiling point of water[…]
– Viscosity: the consistency of a fluid High viscosity: thicker, slower flowing liquid Low viscosity: thinner, faster flowing liquid – The basics of data science: The independent variable (X) affects the dependent variable (Y). If you measure the effect of tutoring hours (X) on ACT score (Y), tutoring hours is independent variable and the ACT[…]
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.
Did you know? The SAT Math section focuses on 3 areas of math: Heart of Algebra, Problem Solving and Data Analysis, and Passport to Advanced Math. It’s important to know the following conversions: inches to feet-divide by 12 feet to inches-multiply by 12 minutes to hours-divide by 60 hours to minutes-multiply by 60 minutes to[…]
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[…]
