Study Notes
Velocity Problems Formula
- Velocity is calculated using two formulas based on units:
- For feet per second: Height (H) = velocity (v) x Time (T) - 16 x (T squared)
- For meters per second: Height (h) = velocity (v) x Time (T) - 4.9 x (T squared)
Quadratic Formula
- Used for solving quadratic equations, applicable across algebra topics.
- Formula: x = -b ± (√b² - 4ac) ÷ 2a
Standard Quadratic Form
- This form is crucial for identifying and applying the quadratic formula.
- Standard form: ax² + bx + c = 0, where a, b, and c are constants, and a ≠ 0.
Quadratic Vertex Form
- Represents a quadratic function, useful for graphing and identifying vertex properties.
- Formula: y = a(x-h)² + k
- The value of 'a' determines the direction of the parabola:
- If a > 0, the parabola opens upwards and has a minimum vertex.
