Semester Exam Review Part 2

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is given by the formula: P = 2(length + width).

Front

If the length of a rectangle is 6 inches more than its width, how can we express this relationship mathematically?

Back

Let width = w. Then, length = w + 6.

Front

How do you calculate the area of a rectangle?

Back

The area (A) of a rectangle is calculated using the formula: A = length × width.

Front

What is the definition of exponential growth?

Back

Exponential growth occurs when the growth rate of a value is proportional to its current value, leading to a rapid increase.

Front

What is the definition of exponential decay?

Back

Exponential decay occurs when a quantity decreases at a rate proportional to its current value, leading to a rapid decrease.

Front

What does the ordered pair (5, 20) represent in the context of Stan and Fran's apple picking?

Back

It represents that each of the cousins will have filled 20 baskets of apples in 5 hours.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables that can be solved together.

Front

How do you set up a system of equations based on a word problem?

Back

Identify the variables, translate the problem into equations based on relationships and totals, and ensure the equations represent the scenario accurately.

Front

What is the difference between linear increasing and linear decreasing functions?

Back

Linear increasing functions have a positive slope, indicating growth, while linear decreasing functions have a negative slope, indicating decline.

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable.
