Front

What is the formula for the area of a sector of a circle?

Back

Area = (θ/360) * πr², where θ is the angle in degrees and r is the radius.

Front

What is the standard form of a quadratic function?

Back

f(x) = ax² + bx + c, where a, b, and c are constants.

Front

What does it mean for a polynomial to have distinct zeros?

Back

It means that the polynomial crosses the x-axis at different points.

Front

What is the vertex form of a quadratic function?

Back

f(x) = a(x - h)² + k, where (h, k) is the vertex.

Front

How do you find the zeros of a quadratic function?

Back

Set f(x) = 0 and solve for x using factoring, completing the square, or the quadratic formula.

Front

What is the quadratic formula?

Back

x = (-b ± √(b² - 4ac)) / (2a) for the equation ax² + bx + c = 0.
