What is a geometric sequence?

Back

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

Front

How do you find the nth term of a geometric sequence?

Back

The nth term of a geometric sequence can be found using the formula a_n = a_1 * r^(n-1), where a_1 is the first term and r is the common ratio.

Front

What is the common ratio in a geometric sequence?

Back

The common ratio is the factor by which each term of a geometric sequence is multiplied to get the next term.

Front

What is the value of 9^(-1/2)?

Back

The value of 9^(-1/2) is 1/3.

Front

What does it mean to solve a system of equations?

Back

Solving a system of equations means finding the values of the variables that satisfy all equations in the system simultaneously.

Front

What is the solution to the system of equations: 5x + 2y = -6 and -2x - 2y = -6?

Back

The solution to the system is (-4, 7).

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.

Front

How can you represent a problem involving classes and credits with a system of equations?

Back

You can represent it with equations that relate the number of classes to the total credits and the total number of classes.

Front

What does the equation f + h = 11 represent in the context of classes?

Back

This equation represents the total number of classes the student needs to take, where f is the number of 4-credit classes and h is the number of 3-credit classes.

Front

What does the equation 4f + 3h = 40 represent?

Back

This equation represents the total number of credits the student needs to earn, where f is the number of 4-credit classes and h is the number of 3-credit classes.
