1. For y = x(5 - x) on 0 <= x <= 5, what is the exact area enclosed by the curve and the x-axis?
ChoicesThe area is the integral from 0 to 5 of x(5 - x). This is [5x² / 2 - x³ / 3] from 0 to 5 = 125 / 2 - 125 / 3 = 125 / 6.
Use Skill Align for HSC Year 12 Mathematics Advanced practice questions and exercise questions after the relevant topic has been taught. Students can start with the pathway demo, then practise by topic and mode.
HSC Year 12 Mathematics Advanced includes 21 practice skills across Functions and graphs, Calculus and applications, Statistics and probability, and Sequences and modelling.
A practice skill is a focused topic or question type designed to help students practise one curriculum-aligned concept with instant feedback and explanations. Skill Align uses practice skills to organise questions by year level, subject, strand, and curriculum focus.
These sample questions are visible on the page before login. They show HSC Year 12 Mathematics Advanced calculus, functions, modelling, probability, and statistics explanations before opening the demo.
The area is the integral from 0 to 5 of x(5 - x). This is [5x² / 2 - x³ / 3] from 0 to 5 = 125 / 2 - 125 / 3 = 125 / 6.
The input x - 3 must equal 2, so x = 5. The output becomes 5 - 2(-1) = 7, so the corresponding stationary point is (5, 7).
For a logistic model, growth is greatest at half the limiting value, so N = 50. Solve 100 / (1 + 9e^(-0.3t)) = 50 to get 9e^(-0.3t) = 1, hence t = (10 ln 9) / 3 hours.
The total unscaled area is the integral from 0 to 4 of 4x - x², which is 32 / 3. The unscaled area from 2 to 4 is 16 / 3, so P(X > 2) = (16 / 3) / (32 / 3) = 1 / 2.
The probabilities place 52 one standard deviation below the mean and 68 one standard deviation above it. The mean is the midpoint (52 + 68) / 2 = 60, and the standard deviation is 68 - 60 = 8.
Differentiate to get f'(x) = 3x² - 8x + 1. At x = 3, f'(3) = 27 - 24 + 1 = 4.
HSC Year 12 Mathematics Advanced practice should make calculus, functions, modelling, probability, and statistics testable without losing the worked method. These examples preview that graph-backed style before the no-login Mathematics Advanced demo.
Mathematics Advanced practice sits inside NSW Year 12 HSC Mathematics course structures, with Year 11 Preliminary context available through the full curriculum coverage, with Skill Align keeping the route focused on the selected maths pathway.
Senior practice is organised by pathway, unit, topic, and mode so students can revise targeted areas rather than sitting a full-paper workflow every time. Skill Align treats practice questions and exercise questions as the same learning workflow: students answer curriculum-aligned questions, review explanations, and move between exercise mode and test mode.
Start with the public sample questions to check the question style, then use the curriculum coverage page to choose a topic that matches the student's current classwork.
These examples are not the full topic list. Use the curriculum coverage page for the complete mapped pathway.
NSW students studying Mathematics Advanced.
Yes. Public sample pages let visitors preview curated Skill Align questions without creating a saved student test record.
No. Skill Align is designed for structured practice after students have learned topics at school or with a teacher.
Yes. Families may search for either wording; Skill Align uses one curriculum-aligned practice page for both practice questions and exercise questions.
Public samples are free before sign-in. Regular full subject access requires the relevant monthly Practice Plan items, managed through a parent account with a separate student login. Exam packs are separate one-off PDF purchases.
