- 1What is the correct terminology for the angles below and what is their relationship?Alternate angles - they are equal
- 2What is the correct terminology for these angles and what is their relationship?Corresponding angles - they are equal
- 3What is the correct terminology for the angles below and what is their relationship?Supplementary/Co-interior/Allied angles - they add up to 180°
- 4What is the correct terminology for these angles and what is their relationship?Vertically opposite angles - they are equal
- 5How do you find the volume of a prism?Volume = Area of cross-section x height
- 6How do you find the sum of the interior angles of a polygon?Sum of interior angles = (n - 2) x 180°
n = no. of sides
- 7What is the sum of one interior angle and its exterior angle?180°
- 8What is the sum of exterior angles?360°
(To find one do 360 ÷ no. of sides)
- 9How do you calculate frequency density?Frequency density = Frequency ÷ class width
- 10When drawing a cumulative frequency diagram, which values should you plot with?Upper class boundaries (x) and cumulative frequency (y)
- 11What does congruent mean?Same shape and same size - identical in form
- 12What does similar mean?Having corresponding sides proportional and corresponding angles equal (same shape, different size)
- 13How do you calculate the area of a sector?
- 14How would you calculate arc length?
- 15Which equation would you write down to describe 'y is proportional to x'y = kx
- 16Which equation would you write down to represent 'y varies directly proportional to the square of x'
- 17Which equation would you write down for 'y is indirectly proportional to the cube root of x'?
- 18If I'm working out the area of a similar shape, what do I need to remember to do with the scale factor?Square it
- 19If I'm finding the volume of a similar shape, what do I need to remember to do with the scale factor?Cube it
- 20How do I calculate interquartile range?UQ - LQ
- 21If I'm increasing something by 8%, what would I multiply by?1.08
- 22If I'm decreasing something by 5%, what would I multiply by?0.95
- 23If I multiply something by 1.025, what have I increased it by?2.5%
- 24What calculation would you carry out if you wanted to work out how much money you would have in the bank if you saved £100 for 5 years at an interest rate of 0.2%?
- 25Which of these graphs show direct proportion?I and II (directly proportionate graphs always go through (0,0)
- 26Which of these graphs show indirect proportion?IV only
(reciprocal graph of the form y = k/x)
- 27What type of graph is this?Quadratic
- 28Does the graph below have a maximum or minimum turning point and how do you know?Maximum because the coefficient of x^2 is negative
- 29Differentiate
- 30What do you get when you differentiate displacement?Velocity
- 31What do you get when you differentiate velocity?Acceleration
- 32If asked to ESTIMATE the gradient of a point on a curve, what should you do first?Draw a tangent
- 33If asked to find the gradient of a point on a curve, what should you do?Differentiate and then substitute the x-value in
- 34If asked to find which point on a curve has a specific gradient, what should you do? Eg:Differentiate, put this equal to the given gradient and solve to find x coordinate (then find y coordinate)
- 35What is the gradient (dy/dx) at a max or min turning point equal to?0
- 36If a turning point of a quadratic graph is at (3, -4), what is the equation of the axis of symmetry?
- 37How do you calculate the gradient of the line on which (x1, y1) and (x2, y2) lie?
- 38Gradients of parallel lines are......Equal
- 39Gradient of perpendicular lines multiply to make...- 1
