Front

How do you calculate the density of an object?

Back

Density is calculated using the formula: Density = Mass / Volume. For a cube, Volume = side length^3.

Front

What is the midline of a trigonometric function?

Back

The midline is the horizontal line that runs through the middle of the wave, representing the average value of the function.

Front

What is amplitude in a trigonometric function?

Back

Amplitude is the maximum distance from the midline to the peak (or trough) of the wave.

Front

What is the period of a trigonometric function?

Back

The period is the distance (or angle) over which the function completes one full cycle.

Front

How do you find the measure of an arc in a circle?

Back

The measure of an arc can be found using the central angle that subtends the arc. The measure of the arc is equal to the measure of the central angle.

Front

What is the formula for solving exponential equations?

Back

Front

What is the significance of the x-intercept in a function?

Back

The x-intercept is the point where the graph of the function crosses the x-axis, indicating the value of x when the function equals zero.

Front

What does it mean for a function to be continuous?

Back

A function is continuous if there are no breaks, jumps, or holes in its graph.

Front

What is the difference between a rational and an irrational number?

Back

A rational number can be expressed as a fraction of two integers, while an irrational number cannot be expressed as a simple fraction.
