DO The diagram shows a building and a man.
The man is of normal height.
The man and the building are drawn to the same scale.
(b) Write down an estimate for the height of the building.
In metres

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

Katie wants to collect over 100 seashells. she already has 34 seashells in her collection. each day, she finds 12 more seashells on the beach. katie can use fractions of days to find seashells. write an inequality to determine the number of days, dd, it will take katie to collect over 100 seashells.

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2
