Unit 2 Linear and Exponential EOC Review

Front

What is the formula for exponential decay?

Back

The formula for exponential decay is V = P(1 - r)^t, where V is the final value, P is the initial value, r is the decay rate, and t is the time.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).

Front

What is the relationship between the slopes of parallel lines?

Back

The slopes of parallel lines are identical.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

How do you calculate the value of an investment after a certain number of years with a fixed percentage decrease?

Back

Use the formula V = P(1 - r)^t, where P is the initial value, r is the rate of decrease, and t is the number of years.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90 degrees).

Front

What is the slope of the line y = 2x - 7?

Back

The slope of the line y = 2x - 7 is 2.

Front

If a line has a slope of 2, what is the slope of a line perpendicular to it?

Back

The slope of a line perpendicular to a line with slope 2 is -1/2.

Front

What is the simplified form of 14d⁷e² - 11d⁷e²?

Back

The simplified form is 3d⁷e².
