Combo 1 Readiness Standards up to Compound Interest

Front

What is compound interest?

Back

Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It is calculated using the formula A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount, r is the annual interest rate, n is the number of times that interest is compounded per year, and t is the number of years.

How do you determine if a relation is a function?

Back

A relation is a function if every input (x-value) has exactly one output (y-value). This can be checked using the vertical line test on a graph.

Front

What is the slope of a line?

Back

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

If a carpenter earns $250 per day, how much will he earn in 5 days?

Back

$1250 (calculated as 250 * 5).

Front

What does it mean for y to be a function of x?

Back

It means that for every value of x, there is exactly one corresponding value of y.

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional grid.

Front

How can you find the average rate of change from a graph?

Back

The average rate of change can be found by selecting two points on the graph, calculating the change in y (rise) and the change in x (run), and then dividing the rise by the run.

Front

What is the formula for calculating simple interest?

Back

Simple interest is calculated using the formula I = PRT, where I is the interest, P is the principal amount, R is the rate of interest per year, and T is the time in years.

Front

What does it mean if a graph does not represent y as a function of x?

Back

It means that there are at least two different y-values for the same x-value in the graph.

Front

What is the relationship between the number of books sold and time in a scatter plot?

Back

The relationship can be analyzed by looking for patterns or trends in the data points plotted over time.
