Diagram shows part of the curve y=27-x^2. PQRS is a rectangle. Length of OQ is t units.
Question 1
y = 27-x²
R
I units
The diagram shows part of the curve y = 27 – x. The points P and S lie on this curve. The points Q
and R lie on the x-axis and PORS is a rectangle. The length of OQ is t units.
(i) Find the length of PQ in terms of t and hence show that the area, A square units, of PQRS is given
by
A = 54t – 2t ³.
(ii) Given thatt can vary, find the value of t for which A has a stationary value.
(iii) Find this stationary value of A and determine its nature.
