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 =

Imagine a new pasture with grass growing on it. every day after the seeds have germinated, the number of blades of grass in the pasture triples. after 18 days, the entire pasture is completely covered in grass. how many days did it take for the pasture to be one-third covered in grass?

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
