Miss Joplin is planning the resources for a maths lesson. She needs...
• 1 ruler per pupil plus 4 spare
. 5 pieces of dotty paper per pupil
. 5 pieces of card per pupil plus 6 spare.
Write down formulae for the number of rulers (r)
and the amount of dotty paper (d) and card (c).
Use p for the number of pupils.
d =
(6)
There are 21 pupils in the class. How many of
each item does Miss Joplin need?
d =
C в

Fredrick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin

Given: hf || jk; hg ? jg prove: fhg ? kjg to prove that the triangles are congruent by asa, which statement and reason could be used as part of the proof? fgh ? kgj because vertical angles are congruent. jkg ? hfg because vertical angles are congruent. fhg ? jkg because right angles are congruent. hfg ? kjg because alternate interior angles are congruent.

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
