or d… The second mark is dependent on gaining the first mark
3. All M marks are follow through.
All A marks are ‘correct answer only’ (cao.), unless shown, for example, as A1 ft to indicate that previous wrong working is to be followed through. After a misread however, the subsequent A marks affected are treated as A ft, but answers that don’t logically make sense e.g. if an answer given for a probability is >1 or <0, should never be awarded A marks.
4. For misreading which does not alter the character of a question or materially simplify it, deduct two from any A or B marks gained, in that part of the question affected.
5. Where a candidate has made multiple responses and indicates which response they wish to submit, examiners should mark this response. If there are several attempts at a question which have not been crossed out, examiners should mark the final answer which is the answer that is the most complete.
6. Ignore wrong working or incorrect statements following a correct answer.
7. Mark schemes will firstly show the solution judged to be the most common response expected from candidates. Where appropriate, alternative answers are provided in the notes. If examiners are not sure if an answer is acceptable, they will check the mark scheme to see if an alternative answer is given for the method used. If no such alternative answer is provided but deemed to be valid, examiners must escalate the response to a senior examiner to review.

Time: 2 hours 8MA0/01You must have:Mathematical Formulae and Statistical Tables, calculator
Candidates may use any calculator permitted by Pearson regulations. Calculators must not have the facility for algebraic manipulation, differentiation and integration, or have retrievable mathematical formulae stored in them.
Instructions• Use black ink or ball-point pen.• If pencil is used for diagrams/sketches/graphs it must be dark (HB or B). • Fill in the boxes at the top of this page with your name, centre number and candidate number.• Answer all the questions and ensure that your answers to parts of questions are clearly labelled.• Answer the questions in the spaces provided – there may be more space than you need.• You should show sufficient working to make your methods clear. Answers without working may not gain full credit.• Answers should be given to three significant figures unless otherwise stated.
Information• A booklet ‘Mathematical Formulae and Statistical Tables’ is provided.• There are 17 questions in this question paper. The total mark for this paper is 100. • The marks for each question are shown in brackets – use this as a guide as to how much time to spend on each question.
Advice• Read each question carefully before you start to answer it.• Try to answer every question.• Check your answers if you have time at the end.• If you change your mind about an answer, cross it out and put your new answer and any working underneath.

12. A student was asked to give the exact solution to the equation
22x + 4 − 9(2x) = 0
The student’s attempt is shown below:
22x + 4 − 9(2x) = 0
22x + 24 − 9(2x) = 0
Let 2x = y
y2 − 9y + 8 = 0
(y − 8)(y − 1) = 0
y = 8 or y = 1
So x = 3 or x = 0
(a) Identify the two errors made by the student.(2)
(b) Find the exact solution to the equation.(2)

12. A student was asked to give the exact solution to the equation
22x + 4 − 9(2x) = 0
The student’s attempt is shown below:
22x + 4 − 9(2x) = 0
22x + 24 − 9(2x) = 0
Let 2x = y
y2 − 9y + 8 = 0
(y − 8)(y − 1) = 0
y = 8 or y = 1
So x = 3 or x = 0
(a) Identify the two errors made by the student.(2)
(b) Find the exact solution to the equation.(2)

Figure 4 shows the plan view of the design for a swimming pool.
The shape of this pool ABCDEA consists of a rectangular section ABDE joined to a semicircular section BCD as shown in Figure 4.
Given that AE = 2 x metres, ED = y metres and the area of the pool is 250 m2,
(a) show that the perimeter, P metres, of the pool is given by
25022πxP x
x= + +
(4)
(b) Explain why 0 500
< <x� (2)
(c) Find the minimum perimeter of the pool, giving your answer to 3 significant figures.(4)

Paper 1: Pure Mathematics Mark Scheme
Question Scheme Marks AOs
1
Way 1
Uses y = mx + c with both (3, 1) and (4, 2) and attempt to find m or c M1 1.1b
m = 3 A1 1.1b
c = 10 so y = 3x + 10 o.e. A1 1.1b
(3) Or
Way 2
Uses 1 2 1
1 2 1
y y y yx x x x
with both (3, 1) and (4, 2) M1 1.1b
Gradient simplified to 3 (may be implied) A1 1.1b
y = 3x + 10 o.e. A1 1.1b
(3) Or
Way 3
Uses ax + by + k = 0 and substitutes both x = 3 when y = 1 and x = 4 when y = 2 with attempt to solve to find a, b or k in terms of one of them
M1 1.1b
Obtains a = 3b, k = 10b or 3k = 10a A1 1.1b
Obtains a = 3, b = 1, k = 10 Or writes 3x + y – 10 = 0 o.e.
A1 1.1b
(3)
(7 marks)
Notes:
M1: Need correct use of the given coordinates A1: Need fractions simplified to 3 (in ways 1 and 2) A1: Need constants combined accurately
N.B. Answer left in the form (y – 1) = – 3(x – 3) or (y – (– 2)) = – 3(x – 4) is awarded M1A1A0 as answers should be simplified by constants being collected
Note that a correct answer implies all three marks in this question
