Inscribed Angle Theorem - correct answer The measure of an inscribed angle is half the measure of its intercepted arc exponential growth and decay - correct answer y=ab^x - b1 = growth - 0b1 = decay discriminant - correct answer d = b²-4ac - d0 = no real solutions - d=0 = one real solution - d0 = 2 real solutions equation of a circle - correct answer (x-h)²+(y-k)²=r² - (h, k) is the center - r is the radius finding the vertex in factored form - correct answer h=s+t/2 - h = x-coordinate of vertex - s = x-coordinate of first x-intercept SOLVE FOR T solutions in a systems of equations - correct answer Ax+By=C Dx+Ey=F - (A/D)=(B/E)≠(C/F) = NO SOLUTION - (A/D)≠(B/E) = 1 SOLUTION - (A/D)=(B/E)=(C/F) = INFINATELY MANY SOLUTIONS measured angles - correct answer the measured angle of the arc is the same as the internal angle of the arc solutions/equations of a graph - correct answer 1- find where the line intersects the x-axis 2- put the zeros in standard form 3- Identify the power by looking at the behavior. If the line goes through the x-axis than the power is odd. If the line bounces the power is even. expected population equation - correct answer = proportion x total vertex form - correct answer y=a(x-h)^2+k - (h, k) is the vertex of the parabola - if a is positive it is a minimum if a is negative it is a maximum imaginary numbers - correct answer i = √-1 i^2 = -1 i^3 = -i i^4 = 1 complimentary angles - correct answer angles that add up to 90 degrees area of an arc - correct answer (πr^2)(degree measure of center of arc/360) circumference of an arc - correct answer 2πr* (degree measure center of arc/360) exponent rules - correct answer a^-n = 1/a^n a^m/n=n√a^m degrees to radians - correct answer multiply by pi/180 radians to degrees - correct answer multiply by 180/pi Distance Formula - correct answer d = √[( x₂ - x₁)² + (y₂ - y₁)²] growth formula - correct answer y=a(1+r)^t decay formula - correct answer y=a(1-r)^t Exterior Angle Theorem - correct answer The measure of an exterior angle of a triangle is equal to the sum of the measures of the two nonadjacent interior angles. types of transitions - correct answer - causation: thus, consequently, therefore, because - contradiction: but/yet, however, nevertheless - additional info: likewise, also, as well - supporting info: for instance, indeed, as a matter of fact - sequence: next, later which vs. that - correct answer "which" is used to introduce nonessential clauses (adds information to a sentence but is not necessary to make meaning), and "that" is used to introduce essential clauses. who vs. whom - correct answer whom follows a preposition like him or her. who follows a subject like he or she. miscellaneous grammar - correct answer avoid punctuation before or after prepositions(at, on, of, to) comma usage - correct answer - listing three or more items - extra information (nonessential) - names and titles, is it essential or no - before a quotation if the word before is "said" or "say" semicolon usage - correct answer 1. closely connected independent clauses that are not connected with a coordinating conjunction a. She is outside; we are inside. 2. between independent clauses linked with a transitional word a. I think we can agree on this; however, I am not sure about my friends. 3. items in a series that has internal punctuation a. I have visited Miami, Florida; Austin, Texas; and Orlando, Florida. colon usage - correct answer 1. after an independent clause to make a list 2. explanations or to give a quote 3. after the greeting in a formal letter, tho show hours and minutes, or to separate a title and subtitle apostrophe usage - correct answer 1. Singular nouns: David's car, a book's theme, my brother's board game 2. Plural nouns: the scissors' handle, boy's basketball 3. Plural nouns with -s: Men's department, the people's adenture 2 or more subjects - correct answer - both singular='s after last noun - both plural=each s' - one singular and one plural= 's and s' modifiers - correct answer Words that describe a noun that can include adjectives, verbs and nouns themselves - keep it close to the noun
