How can you determine if a set of ordered pairs represents a function?

Back

Check if any x-values are repeated; if they are, it is not a function.

Front

What is the formula for the volume of a sphere?

Back

V = (4/3)πr³, where r is the radius.

Front

What is the formula for the total surface area of a cylinder?

Back

SA = 2πr(h + r), where r is the radius and h is the height.

Front

What is lateral surface area?

Back

Lateral surface area is the area of the sides of a 3D shape, excluding the top and bottom.

Front

What is the formula for lateral surface area of a cylinder?

Back

LSA = 2πrh, where r is the radius and h is the height.

Front

What is simple interest?

Back

Simple interest is calculated using the formula I = Prt, where P is the principal, r is the rate, and t is the time.

Front

What is compound interest?

Back

Compound interest is calculated on the initial principal and also on the accumulated interest from previous periods.

Front

What is the difference between total surface area and lateral surface area?

Back

Total surface area includes all surfaces, while lateral surface area only includes the sides.

Front

What does the variable 'r' represent in the formulas for cylinders and spheres?

Back

The variable 'r' represents the radius of the base of the cylinder or sphere.
