Exam-Style Questions.Problems adapted from questions set for previous Mathematics exams. |
1. | GCSE Higher |
The diagram shows part of the graph \(y=x^2-3x+6\).
(a) By drawing a suitable straight line, use your graph to find estimates for the solutions of \(x^2 - 4x + 2 = 0\) to one decimal place.
(b) A is the point (2,4). Calculate an estimate for the gradient of the graph at the point A.
2. | IGCSE Extended |
(a) Show that the equation \(\frac{3}{x+1}+\frac{3x-9}{2}=1\) can be simplified to \(3x^2-8x-5=0\).
(b) Solve the equation \(3x^2-8x-5=0\) showing all of your working and giving answers to three significant figures.
(c) The total surface area of a cone with radius \(x\) and slant height \(8x\) is equal to the area of a circle with radius r. Show that \(r = 3x\).
[The curved surface area, \(A\), of a cone with radius \(r\) and slant height \(l\) is \(A=\pi rl\).]
3. | GCSE Higher |
In the diagram below, which is not drawn to scale, all dimensions are in centimetres and all angles are multiples of 90o. If the shaded area is 698cm2, work out the value of \(x\).
4. | GCSE Higher |
Given that:
$$ x^2 : (5x + 3) = 1 : 3 $$find the possible values of \(x\).
5. | GCSE Higher |
Given that \(x^2 – 8x + 3 = (x – a)^2 – b\) for all values of x,
(a) find the value of a and the value of b.
(b) Hence write down the coordinates of the turning point on the graph of \(y = x^2 – 8x + 3\)
6. | GCSE Higher |
The area of triangle ABC (not drawn to scale) is
$$ \frac{35 \sqrt{3}}{4} m^2$$If AB = \(x+2\) metres and AC = \(2x+1 \) metres, find the value of \(x\).
7. | GCSE Higher |
If \(y = 5x^4 + 3x^2\) and \(x=\sqrt{w+2}\), find \(w\) when \(y = 12\) showing each step of your working.
If you would like space on the right of the question to write out the solution try this Thinning Feature. It will collapse the text into the left half of your screen but large diagrams will remain unchanged.
