The graph of y = x 2x 3 is shown on the axes below.
Draw the graph of y = 5 on the same axes.
Use your graph to find:
the values of x when x 2x 3 = 5
For each example:
1. Write down the mean and standard deviation.
2. What is the information about (what do you think)?

A room is in the shape of a cuboid. Its floor measures 7.2 m by 9.6 m and its height is 3.5 m.
Calculate the length of AC.
Calculate the length of AG.
Calculate the angle that AG makes with the floor.
AC = 7.2 + 9.6
AC = 12 m
