Front

What is the difference of squares formula?

Back

a^2 - b^2 = (a + b)(a - b)

Front

How do you find the perimeter of a triangle given its vertices?

Back

Use the distance formula to find the lengths of each side and sum them up.

Front

What is the formula for speed in relation to distance and time?

Back

Speed = Distance / Time

Front

How do you determine the equation of a line of best fit from a data set?

Back

Use linear regression to find the line that minimizes the distance to all points.

Front

What is standard deviation?

Back

A measure of the amount of variation or dispersion in a set of values.

Front

What is the formula for standard deviation?

Back

σ = √(Σ(x - μ)² / N) where μ is the mean and N is the number of data points.

Front

What does it mean for two variables to be inversely proportional?

Back

As one variable increases, the other decreases such that their product is constant.

Front

What is the quadratic formula?

Back

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

Front

How do you factor a quadratic expression?

Back

Look for two numbers that multiply to ac and add to b in ax² + bx + c.

Front

What is the distance formula?

Back

d = √((x2 - x1)² + (y2 - y1)²) for points (x1, y1) and (x2, y2).
