9th Grade Placement Test Review Cheat Sheet
- Master the Quadratic Formula - Think of it as your algebraic detective tool: plug in a, b, and c into x = (-b ± √(b² - 4ac)) / 2a and reveal the hidden solutions of any quadratic mystery! This formula works every time for ax² + bx + c = 0. Albert.io reference sheet
- Understand Slope and Slope-Intercept Form - Picture slope (m) as the steepness of a rollercoaster track: m = (y₂ - y) / (x₂ - x). Then use y = mx + b to pinpoint where your ride starts on the y-axis and how it's angled. Agrade Ahead blog
- Learn the Midpoint Formula - This is your geometry GPS: the midpoint between (x, y) and (x₂, y₂) is simply ((x + x₂)/2, (y + y₂)/2). It's like finding the perfect halfway house between two coordinate points! Agrade Ahead blog
- Grasp the Pythagorean Theorem - In any right triangle, a² + b² = c² unlocks the length of the hypotenuse (c) when you know the other two sides. Think of it as the triangle's secret code for side lengths! Albert.io reference sheet
- Familiarize Yourself with Area and Circumference of a Circle - Calculate area with A = πr² to see how much space is inside, and use C = 2πr to measure the outer edge. Circles never felt so simple! Albert.io reference sheet
- Understand Arithmetic Sequences - These are number staircases with a constant difference (d) between steps. To find the nth stair, use aₙ = a + (n - 1)d and climb with confidence! Albert.io reference sheet
- Learn Geometric Sequences - Each term multiplies by a fixed ratio (r), like shooting up or shrinking fast. Discover any term with aₙ = a · r^(n - 1) and watch the pattern unfold! Albert.io reference sheet
- Master Exponential Growth and Decay - Model wild population booms or slow radioactive decay with A = A₀e^(kt), where A₀ is your starting amount, k is the growth/decay rate, and t is time. Science and math unite! Albert.io reference sheet
- Understand Radians and Degrees - Switch between rad (180/π°) and degrees (π/180 rad) to ace trigonometry. Whether you're spinning circles or solving sine waves, conversions are key! Albert.io reference sheet
- Familiarize Yourself with Volume Formulas - From V = πr²h for cylinders to V = (4/3)πr³ for spheres, these equations tell you how much space an object occupies. Perfect for all your 3D shape adventures! Albert.io reference sheet
