The Hong Kong Certificate of Education Examination (HKCEE) is a significant milestone for students in Hong Kong, marking the end of their secondary education. In 2010, the HKCEE maths paper 2 exam presented challenges for many students. This article aims to provide a detailed solution to the HKCEE 2010 maths paper 2, helping students understand the concepts and techniques required to excel in the exam.
HKCEE 2010 Maths Paper 2 Solution: A Comprehensive Guide**
The HKCEE 2010 maths paper 2 exam consisted of 40 multiple-choice questions, testing students’ knowledge in various areas of mathematics, including algebra, geometry, trigonometry, and statistics. The paper was designed to assess students’ problem-solving skills, critical thinking, and mathematical concepts.
Let’s take a closer look at some of the questions and their solutions:
In the figure, $ \(O\) \( is the center of the circle and \) \(ngle AOB = 120^ rc\) \(. Find \) \(ngle ACB\) $. Step 1: Recall that the angle subtended by an arc at the center of the circle is twice the angle subtended by the same arc at any point on the circumference. Step 2: Since $ \(ngle AOB = 120^ rc\) \(, \) \(ngle ACB = rac{1}{2} imes 120^ rc = 60^ rc\) $. Section C: Statistics and Probability
Solve the equation $ \(x^2 + 5x - 6 = 0\) $.
