Front

What is the distance formula used to calculate the distance between two points (x1, y1) and (x2, y2) on a coordinate grid?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What does the slope of a linear function represent?

Back

The slope represents the rate of change of the function, indicating how much y changes for a unit change in x.

Front

What is the formula for the area of a circle?

Back

Area = πr², where r is the radius of the circle.

Front

How do you find the midpoint of a line segment with endpoints (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

What is an exponential decay function?

Back

An exponential decay function is a mathematical function that describes a quantity decreasing at a rate proportional to its current value, often modeled as y = a(1 - r)ⁿ.

Front

What is the quadratic formula used to find the roots of a quadratic equation ax² + bx + c = 0?

Back

Roots = (-b ± √(b² - 4ac)) / (2a)

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

How do you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph of the relation at more than one point, it is not a function.

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height of the cylinder.
