1 Front Side of Flash Card..two integers 41 lies between… *to find an answer… Back Side of Flash Card Choose a perfect square SMALLER and BIGGER than 41 The square root of both #s is the answer

2 Front Side of Flash Card Decimal to Percent Percent to Decimal Back Side of Flash Card D P : move decimal 2 spaces RIGHT P D : move decimal 2 spaces LEFT

3 Front Side of Flash Card Probability of multiple coin flips Back Side of Flash Card Multiply probabilities each coin flip

4 Front Side of Flash Card Increase by a scale factor # Back Side of Flash Card Means you multiply original value by factor #

5 Front Side of Flash Card Parallel Slopes Perpendicular Slopes Back Side of Flash Card Both lines have the same slope. Both slopes are the OPPOSITE RECIPROCAL of each other

6 Front Side of Flash Card What is the best test- taking strategy? Back Side of Flash Card TAKE YOUR TIME, GO SLOWLY, AND DONT OVER-THINK THE PROBLEM!!1!

7 Front Side of Flash Card Calculating % commission of a price (total commission) Back Side of Flash Card Convert % to decimal Multiply that by the price

8 Front Side of Flash Card Properties of parallelograms Back Side of Flash Card 2 parallel sides with the same length 2 other sides that have the same length (usually at an angle)

9 Front Side of Flash Card Calculating the y-intercept Back Side of Flash Card Plug in 0 for x and then solve for y. Answer: ( 0, )

10 Front Side of Flash Card What is the equation of a line when given point and slope? Back Side of Flash Card Use the point-slope formula: Plug in values and solve for y.

11 Front Side of Flash Card Graph y=x^2 Back Side of Flash Card x^2 is a parabola facing upwards Positive coefficient

12 Front Side of Flash Card Graph y = -x^2 Back Side of Flash Card -x^2 is a parabola facing downwards Negative coefficient

13 Front Side of Flash Card Graph y = -x^3 Cubic Function Back Side of Flash Card S-shaped graph Looks like negative slope

14 Front Side of Flash Card Graph y = x^3 Cubic Function Back Side of Flash Card S-shaped graph Looks like positive slope

15 Front Side of Flash Card …vehicle traveling at a certain speed… …distance against the wind, and greater distance with the wind… Back Side of Flash Card Use rt=d formula Wind will be added and subtracted from original speed

16 Front Side of Flash Card Polygon Similarity Back Side of Flash Card Polygons need to have the same angles Segment lengths must be in proportion to each other

17 Front Side of Flash Card Polygon Congruence Back Side of Flash Card Polygons need to have the same angles Segment lengths need to be the same

18 Front Side of Flash Card Calc. missing length of a triangle: Back Side of Flash Card Pythagorean Theorem Triangle needs to have 90* box Hypotenuse (c) opposite 90* box

19 Front Side of Flash Card Solving SYSTEMS of linear equations Back Side of Flash Card Plug in x and y values to both equations. Correct answer when both sides equal 5 = 5

20 Front Side of Flash Card Negative exponents… what do you do?? Back Side of Flash Card Reciprocal the number Make the exponent positive Simplify

21 Front Side of Flash Card Order of Operations Back Side of Flash Card Follow PEMDAS Simplify MD and AS from left right

22 Front Side of Flash Card Adding multiple fractions Back Side of Flash Card Make common denominators first Add fractions and simplify

23 Front Side of Flash Card Positive slopes and correlations Negative slopes and correlations Back Side of Flash Card Positive Right side facing upwards Negative Right side facing downwards

24 Front Side of Flash Card Multiplying same base exponents Back Side of Flash Card Add exponents

25 Front Side of Flash Card Dividing same base exponents Back Side of Flash Card Subtract exponents Upstairs guy minus downstairs guy Reciprocal any negative exponents

26 Front Side of Flash Card Exponents outside the parenthesis Back Side of Flash Card Exponents multiply Coefficients and some variables have an invisible 1 exp.

27 Front Side of Flash Card Mean Back Side of Flash Card Average Add up all data points and divide by # of points

28 Front Side of Flash Card Median Back Side of Flash Card Line up all data points (smallest to largest) Pick the guy in the middle (find the mean if there are 2 in the middle)

29 Front Side of Flash Card Mode Modal Back Side of Flash Card # in a data set that you see most often {1, 2, 2, 3, 2} mode=2

30 Front Side of Flash Card Absolute value equation Back Side of Flash Card Should have 2 answers { #, # }

31 Front Side of Flash Card Dependent events Back Side of Flash Card Something can only happen if something else happens

32 Front Side of Flash Card Independent events Back Side of Flash Card Something happening has no effect on something else happening

33 Front Side of Flash Card Sci. Standard Notat. Back Side of Flash Card Positive Exponent: MOVE DECIMAL RIGHT Negative Exponent: MOVE DECIMAL LEFT

34 Front Side of Flash Card Standard Sci. Notat. Back Side of Flash Card Little number (decimal): MOVE DECIMAL RIGHT Big number (#>1): MOVE DECIMAL LEFT Only 1 digit up front!

35 Front Side of Flash Card Area Formulas Back Side of Flash Card Include all of your geometry flash cards.
